Partial Synovectomy in Articular Side of Quadriceps Tendon Verified to Reduce Crepitus in Retrospective Study

This is a surgical study examining whether performing a partial synovectomy (removing part of the lining tissue) on the inner side of the quadriceps tendon during total knee replacement surgery reduces the clicking or grinding sensation (crepitus) that some patients experience after the operation. **You may be eligible if:** - You are scheduled to have a total knee replacement surgery using a posterior-stabilized (PS) implant design **You may NOT be eligible if:** - You are lost to follow-up or pass away during the study - You have unexpected complications such as infection or a fracture around the implant - You have your kneecap resurfaced (patella resurfacing) during surgery - Your surgery is canceled - You decline to participate - There is significant anatomical variation between your two knees making comparison unreliable Talk to your doctor to see if this trial is right for you.
