Total knee replacement (TKR) surgery has been around for decades, and generally speaking, results are very good. In fact, 90% of folks can expect up to a 20-year success rate. The most common reason for a knee replacement is to resolve advanced arthritis.
But what if advanced arthritis isn’t the true cause of your knee problem? Do you really need a knee replacement?
Only 15% of patients with evidence of knee osteoarthritis (OA) actually have symptoms. That means the other 85% don’t have any pain at all. These results are consistent for other joints as well. Signs of degenerating joints, bone spurs, and even meniscus tears all occur normally as you age. While some of the time these things can be the cause of your knee pain – more often than not it’s something else – or a combination of things – that are fully responsible for your joint pain or dysfunction.
Evidence of knee OA shouldn’t be the only factor determining your decision of major knee surgery.
Here are three important things to consider before deciding if a total knee replacement is right for you.
This is one of the most important factors to consider before undergoing major knee surgery. The X-ray might say you’ve got “bone on bone” arthritis and terrible OA – but if your knee pain is fairly tolerable – and you can still do most activities you love – why take the risk of major surgery when you could wait?
Even though knee replacement surgeries are quite common and successful – there are still risks and complications. The most common risk is infection. But you could also end up with blood clots, problems with anesthesia, or an ill-fitting prosthesis that doesn’t function right. Not only that, but people tend to underestimate the 6-12 month recovery that comes afterwards.
If your knee pain is severe and intolerable, and you’ve already tried physical therapy, then you’re probably a good candidate for knee replacement, and the potential risks are likely worth the reward for you. But if your pain isn’t that bad yet, it might be a good idea to wait, and get a second opinion.
There could be other reasons for your knee pain beyond arthritis. If those factors get addressed, you might find you don’t need surgery at all.
In a recent study by Rosedale, et. al (published in the Journal of Manual and Manipulative Therapy), it was found that over 40% of patients with isolated extremity pain, who did not believe their pain could be originating from their spine, responded to spinal intervention.
What does that mean in plain English? It means that you can have knee pain coming from your lower back and not even know it. Severe knee OA doesn’t come out of nowhere. It gradually progresses over time. But when you have knee pain that comes on for no reason, has good days and bad days, and especially if you have knee pain and back pain at the same time – you must get your spine evaluated before undergoing any type of intervention for your knee.
Luckily most surgeons consider knee replacement as a last resort. But if your spine is causing your knee pain and you miss it – you’ll end up down the path of failed knee treatment after failed knee treatment. Then suddenly it will seem as if you’re at your last resort, especially if you’re over 50 and have (normal) evidence of knee OA on your X-ray.
Always get your spine checked by a mechanical pain expert when your knee hurts. It will help you avoid years of mis-guided knee treatment, and could save you from an unnecessary knee replacement.
Typically, with severe or advanced OA of the knee, you’re going to have pretty restricted mobility. And any efforts to improve that mobility will be minimally effective and likely make your knee worse. But if your knee is not consistently stiff, only seems to get tight in certain situations, or perhaps it feels better after you stretch and mobilize it – you may want to think twice before getting it replaced.
That’s because sometimes mobility restrictions in your knee can be caused by something other than arthritis – like a small tear in your tissue that gets “caught” in your joint. If you know how to move your knee joint in just the right way – you can actually remove this restriction. Not only will your knee move normally again, but your pain will go away too.
This is really hard to figure out on your own. It even gets missed by a lot of medical professionals if they aren’t expertly trained in diagnosing mechanical pain. And it definitely doesn’t get picked up by an X-ray or MRI.
If your knee is not terribly stiff 100% of the time, and you’re tolerating most of your favorite activities – the best thing to do is get a second opinion from a trained mechanical pain expert. Because what you might be missing is highly specialized and specific mobility treatment for your knee.
Once your knee mobility is fully and properly restored, you might find you no longer need a knee replacement, or at the very least can put it off another 10 years.
To be clear, I’m not saying you shouldn’t get a knee replacement. I’m saying there’s a chance you don’t need one and it’s important to explore that. I’ve seen so many cases over the course of my career where people didn’t need a knee replacement – but got one because the X-ray or MRI “said so” – and then continued to suffer for years afterwards.
