I had double knee replacements April 2017!! Best decision ever!! I was nervous & scared however I got through it without any problems, until recently! This past summer I finally felt comfortable squatting, yes something I've not done since at least 2 years "before" my surgery! I have not however been able or rather comfortable with kneeling yet. I just can't not because I'm not supposed to but because it bothers me to put complete weight. Again not because of anything wrong it's me, at least that's what surgeon says. Ok getting. back to reason for my post. I have been squatting alot lately working out in yard. For the last 2 weeks my left knee hurts same way it did when I tore my meniscus. I've read here that with TKR I don't need to worry about meniscus tears anymore!!?? So...does anyone have any ideas as to what or why this is happening? I know one thing it's definitely from squatting!! Any opinion is appreciated. Thank you in advance!!

    Two ideas...

    1. The flexion angle of your knee may be too great. PTs want to get you to at least +120. Even going into the 130's is OK. The problem starts at +140 as you are now in "athlete's range". For Yoga enthusiasts, sitting on your heels is a flexion of +161. No PT or doc I've ever talked to feels comfortable with anything beyond 140. The reason is that all my research has not been able to discover the flexion limits of the devices. Yes, there are new ones that are supposed to give you higher flexion but there are no long-term tests to prove their reliability to 25 years as the previous generation of implants. You would need to ask your doc for the manufacturer and model of YOUR device and then call them to find out its limits.

    2. Kneeling down is a very long-term issue that may or may not resolve. The pain comes from the nerves that were affected during surgery and not the knee itself. You must always use a 3" to 4" foam pad indoors and a set of padded knee pads for outside work. Never have your knee in direct contact with very hard surfaces such as tile, hard wood flooring, concrete and more. Old time TKRers say they still have the nerve pain on contact with hard surfaces years and years down the road, Probably nothing that anyone can do about it permanently.
