Stiff knee replacement

Bandaged knee after total knee replacement

So you finally decided to have your arthritic knee replaced. You got through the surgery just fine. As expected, you had some surgical pain, but almost immediately you realized that your arthritic pain was gone. Awesome! Things seemed to be going very nicely, and now you are home...

Your knee may begin feeling tight and warm. This is normal and expected. Healing occurs in part through an inflammatory process. Inflammation shows up as swelling, warmth, and pain. You have been told to stretch, but may be questioning this recommendation now. You may be concerned that because it hurts you could be damaging yourself or your new knee. This is a very common concern. Please resist the urge to stop stretching.

The knee is a complex joint. There several moving parts and potential spaces (otherwise known as tissue planes). During total knee replacement these parts are moved around , the tissue planes are opened. I think it makes sense to patients when they have some pain after surgery. But as the wound is healing on the outside, why does it feel like things are getting worse on the inside?

As the healing process proceeds, the tissue planes that have been opened begin sticking together. Gradually adhesions, or scar tissue, may form between these planes preventing them from gliding properly. Initially this scar tissue is weak, but it will get stronger every day. For this reason, there is some urgency to regain range of motion as soon as possible. This is because after about 6 weeks or so from surgery this scar tissue becomes strong enough that a patient is unlikely to be able to stretch it out any more. The range of motion you have achieved at this point will be how far your knee will move permanently...without additional intervention.

To better understand knee range of motion lets begin with a couple of definitions. Flexion of the knee means bending. When you sit in a chair and your feet are flat on the floor, your knee is bent, or flexed. Extension of the knee means straightened. When you stand up and your knee is straight it is extended.

Now lets discuss these tissue planes a bit.

Tissue layers that must glide following total knee replacement

Tissue layers in the knee that must be stretched following total knee replacement.

The skin must be able to slide over the kneecap (patella). The body achieves this by only loosely attaching the skin to the patella. This loose connective tissue allows motion to occur. Under abnormal conditions, fluid can collect here and create swelling. A potential space such as this is referred to as a bursa. The loose connective tissue found here is called bursal tissue. The specific space, or tissue plane, between the skin and the kneecap is called the pre-patellar bursa. It is shown in purple in my sketch.

The kneecap (patella) is embedded within the tendon that attaches your thigh muscles (quadriceps) to your shin bone (tibia). A tendon is the tissue that attaches muscle to bone. The quadriceps tendon must be able to slide relative to the thigh bone (femur). The area above the patella shown in my sketch as orange is called the supra-patellar pouch.

If either of these tissue planes sticks together, the knee will not be able to bend completely.

In the back of the knee there is a sheet of tissue called the posterior capsule. This is green in my sketch. This tissue is irritated during surgery and will gradually tighten as it heals. If this is allowed to happen, the knee will not fully extend.

So, how do you prevent a stiff total knee? It is not by walking around a lot. It is not by cycling the knee back and forth a lot. It is by gently and progressively stretching. Even though it hurts. The longer you are from surgery, the longer these stretching sessions must be because the scar tissue becomes stronger each day. Gentle progressive stretching works by taking advantage of the viscoelastic nature of biologic tissues.

My basic recommendations:

Extension: Place your heel on something. Make sure your toes are pointing straight up. Leave your knee completely unsupported. Gradually relax your muscles to allow gravity to pull your knee straight. You can assist by trying to gently force the back of your knee down. Maintain this stretch for as long as you can. Longer is better. Try to measure the duration of stretch in minutes as opposed to seconds.
Flexion: Progressively bend your knee. It is very important to relax your quadriceps muscle while doing so. You can use your other leg to help. Place your good foot in front of your ankle and pull back attempting to bend the knees together. Again, do this slowly but progressively. Hold the endpoint for as long as you can. Although it will hurt, do your very best to relax your body. Measure the duration of stretch in minutes as opposed to seconds.
You do not need to repeatedly swing your knee back and forth from full extension to full flexion. In my experience, all of the mid-range range of motion done will not help increase end range of motion, and could actually cause swelling and inflammation which will slow down your progress. It is much better to slowly and progressively focus on one motion at a time.

Future posts will further develop these concepts.

I fx my Patella wired and screwed together 6 weeks ago. Currently passive flexion 90, active around 55-60 lots of pain. My surgeon said I should be at 90 plus by now. He said he has done all he can for now He said come back in 8 weeks. Should I get a second opinion? Can I do more. Currently CPM 6 hours a day PT once a day for 1 hour, ambulating as much as possible.

I would also like to see 90 degrees of flexion at the 6 week mark after open reduction internal fixation of a patella fracture. This is not always the case-for a variety of reasons.

First of all- don’t worry- you will make progress for many months yet to come- with the appropriate exercises.

A couple of your comments are consistent with those I hear from patients with a stiff knee- “I’m doing a lot of walking”, and “I’m using continuous passive motion for many hours.” Unfortunately, neither of these things will make a stiff knee loosen up.

Another thing I hear quite often is - I am doing xxxx strengthening exercises all the time.”

Walking simply does not require much knee range of motion. While it is good for many other reasons, it will not help you to regain knee range of motion. The benefits of walking include improvement in bone density, improvement in muscle tone and strength, reduction in risk for deep venous thrombosis (DVT), otherwise know as blood clots. So it isn’t inappropriate to walk when your surgeon allows you to.

Continuous passive motion (CPM) is a machine that gently pushes a joint back and forth, but doesn’t force endpoints very much. These machines were utilized extensively in the past, and for certain conditions can be quite helpful. I have abandoned their use after knee replacements as the majority of my patients are usually up, out of bed, ranging their knees through a 90 degree arc, waking up and down the hall and stairs and are back home within 24-48 hours of admission. These devices were great when hospital stays were 5-7 days or more and patients spent most of the time laying in bed. Using a modern multimodality pain control regimen including regional anesthesia and intra-articular local anesthetics I found CPM was holding patients back.

Strengthening is great for muscle development and is important, but this is only effective after range of motion is restored. Strengthening will not cause joint range of motion to improve.

Getting back to your question- improvement in joint range of motion requires stretching. I have found sustained stretching (holding the endpoint for many minutes as opposed to a few seconds) is much more effective for a postoperatively stiff joint than the 10-15 second stretches most therapists suggest.

As long as your surgeon has allowed you to progress your range of motion without limits at this time, I would recommend stretching for a cumulative minimum of 1 hour each day, with no days off, and for a minimum of 10-15 minutes each session. Only a single maneuver is required: when trying to regain flexion, flex the knee until it stops, try to use your thigh muscles (hamstrings) to bend it more, and apply additional flexion force manually by gently pulling your ankle toward your buttocks. Simply hold this stretch for as long as possible.

Another method is to lie on your back on a sofa. Let your legs hand over the arm. Slide your butt to one end of the couch- right against the arm of the couch. Your hip should be flexed to 90 degrees. This should allow your knee to be dangling in the air. Relax in this position and gravity will be pulling down on your knee. Stay in this position for as long as possible. If desired- wear a boot or use an ankle weight to apply additional flexion force.

Remember- cycling your knee back and forth will not result in improved motion- sustained endpoint stretching will.

In this blog are articles on the viscoelastic nature of biological tissues as well as articles supporting this sustained stretching technique- which is also very helpful for adhesive capsulitis (frozen shoulder).

You are spending lots of time and effort attempting to rehabilitate. Just refocus your efforts toward more effective techniques and I think you will see progress.

I hope this information is helpful.

1 yr po, 90° bend, surgeon said it's functional?

Christopher Gorczynski, MD link

11/26/2018 05:55:22 pm

@ jacqueline davey 90 degrees is marginally functional in my opinion. I would expect you to have difficulty going up and down stairs normally, and to have difficulty standing up from a low chair using your affected knee. If it is otherwise pain-free and trustworthy, you may decide to leave it along. If, however, you do find it functionally limiting, you would be a candidate for arthroscopic lysis of adhesions with a manipulation under anesthesia. This is very likely to help you regain a truly functional range of motion if you work diligently on maintaining the range of motion your surgeon gets. It is worth discussing this with your surgeon if you are not satisfied with your level of function.

Thank you so much for this advice. I am 3 weeks post op tkr and nearly bought a small pedal machine last night and also went for a longish walk. Woke up this morning feeling very stiff then found your article. Also holding the knee bend for minutes rather than seconds has given me a breakthrough in my recovery.

11/5/2018 08:43:16 pm

Glad to hear that extended stretching is helping you. Consistency (no days off) and long duration, progressive stretching definitely seems to be the most effective, and least irritating method to rehabilitate total knee replacements.

Thank you for this really helpful information. I'm finding the more lengthy stretches are making all the difference and I've stopped being quite so scared of splitting the scar when pushing further with the knee bends. The exercise involving hanging my knees over the side arm of the sofa is really helping get rid of the deep ache from where the tourniquet was positioned during surgery. Why is that?

11/5/2018 08:44:08 pm

I am pleased to hear that extended the duration of stretching is helping you to make progress with your total knee rehabilitation. Stretching over the arm of the sofa allows your muscles to relax during the stretch. Because the tourniquet creates mild trauma to your thigh muscles, allowing them to relax while they are being stretched is probably why you find this helpful. All too often I hear about physical therapy sessions that sound like torture sessions, or strength contests. Gentle, progressive, long duration stretching makes this process much less unpleasant. Thank you for the comment, and keep up the good work!

Dr. Gorczynski,
I’m 13 weeks out from my TKR. The best I can remember (lots of meds) I have had a tight band running just below my patella (front only) and another on the outside edge running at at 45 degree angle. They are tight and like a rubber band (I’m assuming it’s scar tissue).
Do you think that will that go away over time? I’m out of official PT but ride my recumbent bike daily and do strengthening and stretching exercises.
Now that the swelling has gone away and most of the pain I am very active outdoors and can do most everything I could before except get on my knee.
My last flexion measurement was 102. I’m not giving up though and am shooting for 120 hoping for at least 110.
I have lost a lot of weight prior to and after surgery and plan on keeping that off.
Thank you for taking my question about the band issue. I hsve not seen that addressed anywhere.

11/26/2018 05:36:51 pm

This does sound like some scar tissue. To gain more range of motion at this point, you really need to focus on prolonged stretching exercises, maintaining stretches for 30 minutes or longer, multiple times per day if possible, and every day. Since scar tissue tends to contract over time, it is normal to feel the need to work at range of motions exercises sometimes for many months.

11/27/2018 08:30:17 am

Thank you for your reply. I’m clear on your advice for stretching a minimum of 1 hr several times a day if possible.
My question is is it ok to to keep riding my recumbent bike and do strengthening exercises along with these sustained stretches?
8/7/18 was my surgery date. My surgeon has released me and will not see me again unless I make an appointment. He said after 6 weeks he would not do a manipulation. We did not discuss removal of scar tissue. Should I seek further advice (2nd opinion) for removal of scar tissue OR rely totally on these stretching exercises? Thank you

11/16/2018 02:18:56 am

Dr. Gorczynski, I’m sorry but I did want to add, when I exercise ( bike, stretching etc ) the band tightens a lot right afterwards. After a good nights rest it relaxes to its normal tightness which is tight enough it’s very aggravating and in a way dehabilitating.. Thank you

11/27/2018 09:05:28 pm

It is definitely ok to continue riding the recumbent bike as well as progressive strengthening exercises. A simple manipulation is unlikely to be very effective beyond 6-8 weeks maximum. I recommend that you continue doing exactly what you have been doing. Particularly working for long periods on regaining deep flexion. I have seen patients gradually improve their range of motion for up to an entire year from surgery. Persistence and patience will usually pay off. Ice and anti-inflammatory meds will assist you. If, at a year from surgery, you have not regained a range of motion that is acceptable to you, you could consider undergoing arthroscopic lysis of adhesions and manipulation. But, this is not something I would encourage you to do at this point because there is an excellent chance you will correct this on your own.

I am 6 weeks post knee replacement. I achieved 115 deg. range of motion at 10 days post op. I now have 121 deg. ROM but don't seem to be progressing beyond that. I have been relatively pain free but my knee is very stiff. I am very flexible and do extensive stretching 5 times a week. I will begin stretching daily per your advice. I will begin holding my stretches longer.
I am not understanding why I seem to be stiffer and more uncomfortable than a week ago. I am using ankle weights on both legs for 2 exercises..1 1/2 lbs.weights each. The weight is causing lower shin minor bruising on my knee replacement leg. I ride my recumbent bike 30 minutes with resistance each exercise session to warm up before stretching.

Any ideas about why my knee stiffness is worsening? Thank you for your help.

1/4/2019 11:51:02 am

A 121 degree arc of motion is excellent, and should be sufficient for all reasonable activities following total knee replacement. It is possible to regain even more motion, but this takes a great deal of work and is not a guarantee of better function. Scar tissue tends to thicken and contract over time. This could be why you are feeling a bit stiffer. Thankfully, this process does not last forever. I would expect this feeling of increasing stiffness to end over the next couple of months. Simply continue gentle, long duration stretching to maintain (or slightly improve) your already excellent range of motion. As for the 1.5 pound weights, if they are causing irritation, I would discontinue them. Simply walking, riding your resistance bike with low resistance, and time will help you to regain function. Gradually add double leg squats, then consider single leg squats, holding something to help with balance.

Sorry I forgot to mention on my previous post that I am a 68 year old woman in excellent health.

1/4/2019 01:55:09 pm

Dr., thank you very much for your encouraging reply. You have saved me worry and second guessing my progress. Very much appreciated!.
I am not sure if any of your patients cannot tolerate narcotics Since childhood I have been deathly allergic to all narcotics. I was naturally very concerned about pain after my knee replacement. I religiously did leg/knee strengthening exercises and stretches for 6 weeks prior to my surgery. I had a block during the surgery and was fully awake. I have had very little pain....just stiffness. I take Celebrex and tylenol for pain. I have not really needed anything else. I also used an ice therapy machine for 2 weeks after the surgery. My second knee replacement is February 25.
Cathleen

1/4/2019 02:29:08 pm

I do have patients that either don't want or don't tolerate narcotic medications and are similarly able to rehabilitate their total knee replacement using only ice, tylenol, and NSAIDS. The regional anesthetic block we use definitely makes a big difference for the first 20+ hours or so. Best of luck on your second knee replacement! The nice thing is that after this....you have no more knees to work on....

Dr., I'm only 5 days post op from my TKR surgery and have yet to have my follow-up appt. with my surgeon or my first PT session. I'd been improving daily... less pain and discomfort... easier to walk and stretch. I've been doing my exercises religiously and then suddenly today my swelling and stiffness increased. It actually feels like I have an invisible ace bandage stretched around my knee! I've continued with my stretching exercises and am actually even holding a stretch longer... but this stiffness continues. Is this temporary or should I be concerned about some longer lasting effect? Thank you so much for your reply.

1/14/2019 09:46:28 pm

Your experience is not unique. It is common for patients to feel that recovery is quite easy for the first few days following surgery and then feel that their progress becomes much more difficult. This is so common, in fact, that we tell our patients to expect the second week to be less pleasant than the first.

There is an inflammatory cascade that happens when your body is traumatized. Surgery causes injury to the body. This injury induces an inflammatory cascade. It takes your body a while to mount this inflammatory response. In general, I would expect this inflammatory cascade to peak around 10-14 days postoperatively.

Additionally, as your body begins to heal, tissue planes begin trying to "stick together." This early scar tissue makes stretching more challenging.

It is crucial not to discontinue stretching during this time. The mistake is to let the pain suggest you are doing something inappropriate. You only have a few weeks to regain a functional range of motion, and each day that goes by allows the scar tissue to become more robust. This means that delaying stretching only makes subsequent stretching attempts more difficult.

Do your very best to relax mentally and physically during stretching sessions. While you do not need to use high forces during stretching, it is usually better to extend the duration of stretching and to add multiple sessions throughout the day. Additionally, the use of ice can help reduce some pain and inflammation. If your surgeon allows it, anti-inflammatory pills can also be helpful during this time.

Once you have achieved a functional knee range of motion, and the inflammatory phase of the healing process is behind you, your knee will feel better and better, and should ultimately become pain-free.

I am 10 weeks post-op TKA. My flexion has varied of late from 125 to 127 with passive assistance. I have maintained a slight degree of swelling which my PT assures me is not impeding my progress. However, my walking has been consistently sub-par and in the last few days I've developed the that band that so many people have referened. I was very interested in your information about stretching, which my PT hasn't instructed me to do. Since reading your blog, I've been doing prolonged stretching for a couple of days and plan to continue. At times it seems to be helping, but I wonder if I've gotten to this information too late in my recovery and will need more aggressive treatment by my surgeon.

1/17/2019 08:39:12 pm

If you have achieved 127 degrees of flexion and have full extension, you should be in great shape. I would expect an excellent result. At this point I would recommend simply maintaining the range of motion you have achieved, and allow the inflammation to subside gradually as your knee heals. Patience is key. There is no reason for you to be anxious at this point, the hard work is behind you. At this point I would expect your knee to gradually settle down and feel better and better as months go by.

I am a 70 year old female 7 weeks out from TKR. I had my right knee replaced in 2017 and now my left knee Dec 2018. I have that tight band that has been spoken about on here and only 90 flexion so far, it was stuck at 78 for 3 weeks. I’ve just started doing the longer stretches you recommended and already I can feel the difference. I think my Physio will be pleasantly surprised at my progress so far. I was too frightened to “push it” as I thought I would break something. Thank you for your suggestions they do help!
PS... I am only taking Osteo Panadol and Celebrex and have been since my op as I had adverse reactions to all other meds..even though I was on them for the other knee, I must admit I feel better without the stronger ones.

1/25/2019 10:49:30 am

It definitely sounds like you got off to a bit of a slow start. 90 degrees always seems to be a "sticky spot" with regard to range of motion.

If you have not done so already, check out the videos I posted using a yoga band to help stretch beyond 90 degrees of flexion.

At this stage following surgery you will really need to be persistent with long duration stretching to regain functional range of motion.

If you are still stuck around 90 degrees of motion at 7 weeks, I would strongly recommend discussing possible manipulation under anesthesia with your surgeon. This usually helps you get back on track with your range of motion.

The trouble is, most patients are unable to achieve much improvement in range of motion on their own beyond 6-8 weeks from surgery. A manipulation not only rapidly advances this range of motion, but buys the patient a few more weeks to make further gains in motion.

Beyond 8 weeks, if range of motion is inadequate, additional improvement usually requires an invasive procedure (arthroscopic lysis of adhesions prior to manipulation.) This obviously entails additional risk and ideally is avoided.

I had my first total knee replacement on 11/14/18 and the second one in 12/26/18. The first one was a breeze - the second one, not so much. Four weeks post surgery, I am having trouble even reaching 110 range of motion. My incision is healed yet, the sensitivity is nearly unbearable. I can’t tolerate even a light cloth touching it. I do the stretching exercises as recommended and still have therapy twice weekly. At the last visit, the therapist found an area that was extremely sore, to the right and back of my knee. He suggested I have damage to a tendon and recommended self massage. Could this be a barrier to healing?

1/25/2019 10:41:41 am

Every patient has a somewhat different experience when rehabilitating a joint replacement. A subsequent joint replacement can even feel different to the same patient. In my opinion, 110 degrees at 4 weeks is fine. I would recommend continuing to stretch for long periods of time as I recommend elsewhere in this website. The longer the better. I would expect another degree or 2 of improved range of motion for another couple of weeks time. That should allow you to regain at least 120 degrees of motion. This should be more than adequate for all desired activities.

Touching and massaging the knee along with ice should help reduce the hypersensitivity. Anti-inflammatory medication (oral or topical) can also be helpful, but I would discuss this with your surgeon. If there is a point-tender spot that does not improve with time, I recommend discussing this with your surgeon.

Dr. Gorczynski:

I am six weeks out from left TKR. 63yo male in excellent health. 5-11, 158 pounds. I came out of surgery well. PT initiated very aggressive therapy. I was 120 degrees flexion at 2 weeks and 130 degrees at 3 weeks, with less than 1 degree from straight. Still pushing both. PT has had me doing athletic therapies like running up and down stairs, body weight squats, wall sits, static and walking lunges and other drills. I have been riding a stationary bike for 30 minutes and have walked for 40 minutes. I have not used an assistive device since Day 10. However, I have also developed swelling above the kneecap and along the lateral side of the knee. It is always stiff and painful at this point. I have been pushing through it in PT and gym training of my own, which has included low-weight single leg presses. But it is becoming problematic. Feels like a tourniquet across the top of my knee. Very tight. While my gains in PT and gym have continued, I'm actually going backward in daily life. I am taking no meds. Sleep is problematic. Concentration level at work is low because of the pain. I saw my surgeon at 6 weeks and he was thrilled and said the swelling will subside. Implant looks good. But I am worried. The question is: Did I do too much? And what is the cost?

1/25/2019 10:35:38 am

It is very easy to become a bit impatient when rehabilitating after total joint replacement. It is important to understand that the healing process truly takes at least a year(and perhaps even longer) to be complete.

Swelling indicates inflammation. Some inflammation is expected and unavoidable after surgical trauma. Overuse also may cause inflammation.

My recommendation is: maintain your knee range of motion. Reduce the repetitive and higher impact exercises. Let your knee calm down.

As long as your knee range of motion is adequate, time will take care of everything else. When you are feeling better, and a few weeks have elapsed, gentle strengthening can be resumed. I would focus on hip and core strength. It is really too soon to be aggressively strengthening the muscles about your knee.

My sense from your message is that there will be no long-term consequence from the overuse your knee was subjected to. Let it calm down, and then gradually advance activities. Remember, this is a long-term process. Your patience will be rewarded.

Hey Doc,
I had bilateral TKR’s last April. I have good range of motion and am finally walking well. ROM 125 in each. No real pain but stiffness on the knee surface, best described in your diagram as “purple”. I am happy to have straight legs, ability to stand for longer periods of time and to have ROM that allows for me to ride a bike. However stairs are still with discomfort due to this tightness? Scar tissue? How do I expedite or stretch this area? I have tried massage & shock wave therapy. Any ideas?

2/9/2019 08:03:19 pm

The purple in the diagram above represents the tissue plane between the skin/fat in the front of the knee and the kneecap (patella). These tissues must slide relative to each other to allow normal knee flexion. That being said, your 125 degrees of flexion suggests well done rehabilitation, and I doubt your range of motion is interfering with stairs.

The tissues around your entire knee are usually thickened a bit after surgery (permanently) as there is normal scarring expected. Long-term, this generally does not cause any significant discomfort.

Difficulty on stairs, particularly in the front of the knee often suggests hip weakness. Another common complaint associated with this is aching pain in the front of the knee with prolonged flexion (for example in a movie theater or back seat of a car.)

Thankfully, there are a few simple exercises that usually make a tremendous difference. I have an entire blog posting focused on this:

I am 61 yrs young, I had both Osteo knees replaced using Conformis, 6 months ago 8/9/18..Before hand I started exersizing, riding a bike, & swimming to get in better shape before surgery..I had excellent exstension after surgery, everything went well, but my right knee more often that not is super tight at times, feels like a tight band around the knee, and up into my inner area & front of leg..like a pulling..I have continued with exer. 3 x a wk for 30 minutes, & I walk 15 to 30 min. every day on my treadmill as well as 15 min 3x a wk on my bike..Also my scar is darker on this knee..My left knee feels great other than a little stiffness if I sit too long..Can u suggest anything I might try? I also eat healthy to try and improve..I rarely do steps there are none in my home..could that be it? tks so very much!

2/9/2019 07:56:38 pm

From your comment, I presume both knees were done under the same anesthetic. Thus, both scars should have similar appearance. While I would expect continual improvement for up to an entire year or more from surgery, it is strange that your knees feel so different. If this is significantly irritating to you, it is worth discussing this with your surgeon to see if he/she recalls any differences intra-operatively, or if there is any soft tissue balance or range of motion difference between your knees. If your range of motion is not symmetric, I would focus on long duration stretching in an attempt to equalize and maximize your motion bilaterally.

My knee is so stiff and 8 weeks after surgery what can I do to help this. I stretch every day with no relief.

2/9/2019 10:03:14 pm

If you are not happy with your range of motion at 8 weeks postoperatively, you could be a candidate for manipulation under anesthesia. I consider this a way to "catch-up" to where you should be at this point. It is important not to delay. I usually perform this when needed at 6 weeks post-op. Much beyond this, the scar tissue has become too robust to make much gain...in this situation an arthroscopic procedure needs to be performed first to cut the scar tissue prior to manipulation. Obviously, an invasive procedure is much less desirable than a simple manipulation. Therefore....call your surgeon this week to discuss manipulation ASAP.

Here is a link to an article I wrote on this topic.

I had right knee replaced jan 15 2018. I have had pain on left side of that knee since. Had arthroscopic sept 7 to break up scar tissue and bend. I was able to bend to 121 after that surgery but with great pain. My pain is worse and range of motion is too. I still go to gym twice a week. It usually takes me a few days to get over my work out which is not that strenuous. I did not have much pain prior to surgery unless I had to walk great distances (shopping, yard work). I have had a nerve block and nerve ablation (very painful). So far no relief. What do I do now? Live in pain with a stiff knee? Not what I planned when I retired. I am 69 and in great physical shape except for the knee. My mental state is suffering too.

2/10/2019 11:47:54 am

A stiff knee can be very frustrating- both to patients and to surgeons. Assuming the knee was properly balanced during surgery, a stiff knee suggests inadequate rehabilitation (stretching) in the early postoperative period. Once stiff, regaining normal motion without pain is very difficult. That is why I suggest the key is to regain full functional range of motion within the first 6 weeks postoperatively.

Once stiff, pain is a common complaint.

It is very important NOT to avoid stretching because of pain.

If your knee range of motion is inadequate for normal desired activities, and your pain level is unacceptable at this point, it is important to ensure your prosthesis is appropriately placed (all angles and rotation are correct), and that there is no evidence of infection.

It is possible (although far from ideal) to undergo revision knee replacement surgery under these circumstances. Clearly this entails risk. Most concerning is the risk of infection. Revision surgery is most predictable if the underlying problem can be clearly identified. If the problem is poorly positioned prosthetic components, this can be fixed. If no cause can be identified, then it is crucial to make up your mind that early rehabilitation will be done differently next time....regardless of pain level.

Long duration stretching is absolutely mandatory.

I would also plan on using a static stretching brace like a JAS (Joint Active System) brace to help facilitate extended progressive stretching.

I have found such braces quite helpful over the years. I would discuss this with your surgeon. In fact, I would obtain one of these (or similar) braces and use it diligently for several months before proceeding surgically. The long periods of time spent at the endpoint of motion will usually allow progressive range of motion improvement. Even if you do not achieve significant gains, you are training your self to endure the discomfort for long period of times and getting in the habit of stretching every day without any days off. This will be very helpful should you eventually decide to undergo revision surgery.

To summarize:

1- Ensure your prosthesis is implanted correctly. A second opinion is always reasonable. Additional imaging is often necessary.

2- Rule out infection.

3- Train your body to endure long duration stretching.

4- Consider the use of static bracing to help stretch for long durations.

5- Stretch every day for months prior to considering surgery.

6- If surgery is ultimately deemed necessary, make sure you stretch adequately immediately and consistently following surgery, every day, until your knee is cool, calm, and functional.

The reason I focus so much on long duration stretching is that your tissues are viscoelastic. That means they will yield to long duration tension.

Early after surgery, no scar tissue has been able to develop. Stiffness at this point is due to the pain and swelling of acute inflammation. Nothing is physically blocking range of motion.

As weeks go by, actual scar tissue devleops between tissue planes and the undersurface of the quadricep tendon scars down to the anterior femur just above the knee. As this occurs, actual physical resistance to motion occurs.

Scar tissue starts out wispy and weak. It is easily stretched. This tissue becomes more robust with time, and ultimately quite rigid. The farther a patient gets from surgery, the more challenging it is to rehabilitate.

I can not emphasize this enough: the time to regain range of motion is immediately after surgery. A functional range of motion needs to be obtained by 6 -8 weeks from surgery. Beyond this time, more aggressive/invasive management is usually necessary.

I am 8 weeks out of total knee replacement. Rangeof motion is 127 . But I am in more pain and tne knee feels stiffer. I stretch every day. What can help this.
