Thank you all for sharing your stories. I'm also considering a spacer replacement surgery. I can sit and rattle my knee side to side very easily with little effort and with a great deal of sideways movement, clicking, and knocking sounds. I had total knee replacement (TKR with mobile bearing unit) on my left knee at age 46 in 2018, which included a lateral release during the procedure, a shaving of tissue on the lateral side of the knee in order to put the patella back in place. Prior to TKR this knee had several arthroscopic procedures as well as one ACL reconstruction over many years. There has been a great deal of lateral movement (float, play) in the joint ever since the TKR, along with associated pain and swelling. Range of motion is full for a TKR with extension reaching to 0 degrees, yet pain at flexion endpoint, which is probably common with TKR. I am naturally very flexible. All X-rays and nuclear bone scans look beautiful. If anyone has had similar issues, I would greatly appreciate your feedback, especially concerning the consideration for spacer replacement. Thank you.
