Who can and who can’t kneel after knee replacement

For some people, there may be no choice, they will need a knee replacement. One of the problems encountered after knee replacement is the patient’s inability to kneel. What makes this problem so frustrating for some, as we will see in the research below, is that there does not seem to be a consistent reason why people who should be able to kneel after knee replacement cannot.

Now if you are exploring a knee replacement, we typically find that people who can can still bend their knees, are able to put weight on their knee in a kneeling position, and are able to lift themselves up from bed, out of a car, or from a low position, are realistically good candidates for our non-surgical treatments. However, each individual varies and this is not to say this would be characteristic of everyone. You can contact us below and we can help assesses what is happening in your case.

Now if you already had a knee replacement and are running into kneeling challenges, let’s cover some research and clinical observations.

Our patient Jeannette had issues with spinal stenosis and problems post knee replacement.

Jeannette describes a foot tingling problem. She cannot sit down and relax at the end of the day, it is uncomfortable for her to put her feet up or down because it is tingling. She had a nerve conduction study that shows an injury to her peroneal nerve. The peroneal nerve branches out from the sciatic nerve. As it provides sensation to the front and sides of the legs and to the top of the feet, damage to this nerve would result in burning and tingling or numbness sensation in these areas. Further damage to this nerve would also cause loss of control in the muscles in the leg that help you point your toes upward. This can lead to walking problems and possibly foot drop, the inability to lift the front of the foot or ankle. Knee and hip replacement are leading culprits in the cause of peroneal nerve injury.

In Jeannette’s case she had two knee replacement surgeries in that knee. After the first knee replacement surgery the implant started to protrude away from the limb. The knee replacement became loose. The second surgery to fix the first one occurred in 2015.

It was determined after examination that Jeannette’s knee ligaments were loose. Her knee was hypermobile and unstable. This was causing pressure on her peroneal nerve. Knee ligament damage and weakness is also a complication of knee replacement surgery and is discussed further below.

The ability to kneel goes beyond religious observance. It is the ability to get up after a fall. It is the ability to care for one-self. It is the ability to preserve the other knee that is not bad enough to get replaced.

For many people, the ability to kneel goes far beyond religious observance. In many patients we see, who had knee replacement, or are exploring their options, little information is given or was given in regard to their the ability or later to find out, inability to kneel. This became, or became crucial when they realized the ability to kneel, is the ability to get up after a fall and put pressure on the bent knee and their ability to go about their daily chores.

We hear things like this. The grandmother

I had the knee replacement. I was told that I could not kneel anymore, if I had to kneel, I had to put a lot of padding down on the ground. I like to clean, I like to get on the floor and scrub. My washer and dryer are front loaders, before I had the knee pain I would sometimes find it easier to kneel rather than bend over. I have grandkids, I like getting on the floor with them to play.

I was told that the hardware from the knee replacement may make kneeling painful. I was reassured that I would not damage the hardware if I knelt but I should use the padding. So I got my husband to help me and I tried to start practicing kneeling at home. I put a lot of pads down, it was uncomfortable, but the real problem was I had no idea how to get up. My “good knee,” the knee that did not need the knee replacement or was not that far gone enough to get one, and my new knee, because of muscle atrophy following the surgery, were neither strong enough to get me up again. I was on the ground, I could not get up by myself.

We hear things like this. The home improvement construction guy

I had to get the knee replacement. I was very aggressive in my rehab as I had to get back to work.  I came back sooner than I should have and was lucky that it did not set me back. My problem is that I am over compensating now and “my good knee,” is deteriorating.

Let’s stress again that many people have great results with their knee replacement. They do not have problems with kneeling or other complication. This are people we do not typically see in our office. We see the people for whom expectation of what their knee replacement could and could not do for them was not met.

For more information on getting back to work please see our article: How fast can I return to work after knee replacement? 15 to 30% of patients do not return to work 

It’s not my knee replacement that is the problem, it is my other knee.

Expanding on the “other knee,” problem

In Australia, doctors at the University of Wollongong, examining why patients who should be able to kneel after knee replacement, did not kneel, wrote in the Journal of orthopaedics and traumatology (1), about the problems of the other, non-replaced knee.

Here is what they found:

Maybe it is not in your knee but in your head. Nerve pain versus in your head pain

We have been helping people with a lot of musculoskeletal difficulties for 27 years. The number of people who have been in our office because they were constantly told that their problems were not in their joints but in the head were vast. Many times we find the problems are not in the patient’s head but are actually in the joints.

This concept that a patient is having difficulty kneeling because they have a fear of kneeling or rather a fear of the pain kneeling may cause them is not a new idea but it is the subject of a lot of current research. A study from March 2019 published in the medical journal Knee (2) from doctors in the United Kingdom asked the question, Why do patients not kneel after total knee replacement? Is neuropathic pain a contributing factor?

Here are the summary points of this research:

The findings:


“Kneeling ability varies greatly post-knee replacement, and is multifactorial. Greater pain is a contributing factor to the inability to kneel postoperatively, but this appears to be nociceptive rather than neuropathic in nature.”

Comment: If kneeling is an important part of your life, you should discuss your ability to do so with your doctors before you being any treatment.

60-80% of patients reporting difficulty kneeling or an inability to kneel

How big a problem is this? In one study 60-80% of patients reporting difficulty kneeling or an inability to kneel

Also from the United Kingdom, researchers at the University of Bristol wrote in their July 2019 study published in the journal EFORT open reviews,(3)

People should be able to kneel after knee replacement – why aren’t they? Research: It has nothing to do with the knee replacement

Let’s look at a January 2019 study in the Journal of Knee Surgery. (4) It comes from  the Department of Orthopaedic Surgery, The Johns Hopkins University.

Here are the summary points:

When a patient says “I just can’t kneel.”

Let’s look at another study looking for answers, here we have doctors at the University of Bristol  in the United Kingdom publishing in the journal Disability and rehabilitation, April 2019 (5)


So can we do anything about it? When it is a problem of the other knee?

Clearly knee weakness and instability in the “other knee,” will present problems in kneeling. If your knee is not bad enough for another knee replacement and you would like to explore other options please consider a review of the following information:

The evidence for Prolotherapy Injections for knee osteoarthritis

In this article, we will update new information and discuss Prolotherapy knee osteoarthritis injections. The knee is the most common joint treated with Prolotherapy at Caring Medical. We use a comprehensive Prolotherapy approach that stimulates the natural repair of connective tissue.

  • Prolotherapy research shows significant improvement in selected patients with knee osteoarthritis.
  • Treating the whole knee joint as opposed to selective parts of the knee is more effective in alleviating knee pain and healing the damage.

The path to knee replacement is inevitable unless you address the knee as a whole and not a problem of only bone on bone

Platelet Rich Plasma for Knee Osteoarthritis When it works When it will not work and When is it better than other treatments

In this article, we are updating research and clinical observations in the use of Platelet Rich Plasma Therapy (PRP) for the treatment of knee osteoarthritis. We will also explain why PRP may not work and how getting a single PRP injection is NOT PRP Therapy and will usually lead to unsatisfying long-term results.

He or she may have made a curious recommendation to you. Platelet Rich Plasma Therapy injection. You ask, what is that? It is then explained that your blood is going to be used as an injection to try to repair and regenerate your damaged knee tissue, mainly your cartilage.

How does it work?  You ask. You then learn that there are healing platelets in the blood that when concentrated and injected back into your knee may provide you with pain relief by way of regenerating, repairing and replacing damaged knee tissue.

In this brief video, Dr. Hauser demonstrates PRP to the supportive ligaments of the knee. PRP injections have the blood-red color. He is also demonstrating Prolotherapy injections to support the PRP injections. The Prolotherapy injections are clear in color. Prolotherapy is an injection of a simple sugar, dextrose. Dozens of research studies have documented Prolotherapy’s effectiveness in treating chronic joint pain.

So can we do anything about it? When it is a problem of the knee replacement knee

Can we help you with your continued knee pain after knee replacement surgery? In this article Problems after knee replacement Finding help for post-replacement pain we will explore the problems identifying the source of knee pain after knee replacement and how identifying and treating soft tissue damage may be the answer to pain after knee replacement.

In this video, Ross Hauser, MD explains the problems of post-knee replacement joint instability and how Prolotherapy injections can repair damaged and weakened ligaments and that will tighten the knee. This treatment does not address problems of hardware malalignment that our patient Jeannette described in the video above. 

Summary of this video:

The patient in this video came into our office for low back pain. I did a “straight leg raise test,” in this patient to help determine if his back pain was coming from a herniated disc. During the test I noticed a clicking sound coming from his knee. The patient had a knee replacement. It is very common for us to see patients after knee replacement who have these clicking sounds which coming from knee instability. This is not an instability from hardware failure. The hardware may be perfectly placed in the knee. It is instability from the outer knee where the surviving ligaments are. I believe that this is why up to one-third of patients continue to have pain after knee replacement.

Dr. Hauser performs an ultrasound scan of the patient’s knee. A small, gentle stress on the knee reveals hypermobility. This is the from the ligaments’ inability to hold the whole knee joint in place. Prolotherapy can be very successful in helping patients who had a knee replacement and still have knee pain. The treatment tightens the whole joint capsule.

In this video David N. Woznica, MD discusses what we see in patients who come in with knee pain in the knee that they had replaced.

Many of the patients that we see with knee pain after knee replacement have pain on the outside of the knee. This is where the ligaments and the tendons are. Most often these connective tissue are damaged and under constant strain. This causes the the knee to wobble, unstable, and cause hypermobility. This pulls and tugs at the ligaments and tendons which causes the patient a lot of pain.

Some patients have nerve irritations, such as Jeannette did in the above video. This nerve irritation can be below or above the knee or along the kneecap. We would treat these problems with nerve release therapy.
