Knee Hyperextension After TKR

Posted by brendaem @brendaem, May 18, 2023

Has anyone who has had TKR experienced a problem with backwards hyperextension of the joint? I had TKR in October 2019. My recovery has been complicated by a sacroiliac joint issue with radiculopathy that has responded to injections and LOTS of PT. However, my knee continues to hyperextend. My ortho X-rays are normal, and the surgeon says sometimes it takes a year, 18 months, 2 years to fully recover. It’s been 3.5 years now and they’re telling me that maybe I need different hardware in the knee. Maybe?? I don’t want another surgery based on a maybe! Has anyone else had to deal with this?

Interested in more discussions like this? Go to the Joint Replacements Support Group.

This is the first time I've heard of hyperextension after TKR. Usually it's just the opposite and you have to do exercises to get extension to zero, or very close to it.


I have this. It is scaring me to death. My tkr was 12/2020. I did PT for a full year- 2021. I did 6 months of therapy in 22/23'. Now... back in therapy. Have seen 3 different neurologist and neuromuscular.

Have you had any resolution?
