Scar tissue after knee replacement

Hello all, I had a TKR of my left knee 4 months ago. I am stuck at about 95 degrees flexion. I have very sharp pain behind the knee when trying to bend past that. The MRI shows a very swollen Popiteal muscle, but my doctor says this is unusual and isn't quite sure what is causing this sharp pain. I was taken out of p.t. and just resumed it again. The pain sometimes is on the outer side of the knee as well. Has anyone experienced this sharp pain behind the Knee? This is really prohibiting the ability to bend the stupid knee! I have crazy tightness across the knee as well. I'm guessing scar tissue is the cause? Unfortunately, I have a bad ankle/foot on the opposite side too, it makes walking a challenge. I knew the recovery would be harder due to my limitations, I'm just frustrated, upset and hoping for a positive turn around. This site is great, the info I've read from everyone is so helpful. So, anyone with this behind the knee pain PLEASE...id love any info you have. Thank you

Hello. I am new to the forum and i still 2 yrs later experience sharp behind the knee and the outer part of my knee as well. Hasn't gotten better nor has it gotten worse since surgery. I've done 3 stints of rehab and now starting number 4. I have no idea what's wrong nor does the 3 surgeons I've had look at it for different opinions. I am not ready for a revision but they said its an option. Quite frustrated at this point.

Hi, I'm having the same problem as you have, just went for a CT scan. Pain behind my knee everytime I stand up. I have to wait before I can put my full weight on my leg so I can walk, than I limp for a while and than I can finally walk "normal". This is also why I had a very hard time in PT when they pushed my leg to get it to bend, the pain was unbearable. So what have they done for you? Hoping your answer will give light to my same problem.

You might want to look into the possibility of a bakers cyst behind the knee. I developed one and had to massage and keep pushing on it to get rid of it or make it smaller. Painful to push on it but can dissolve over time with massaging.
