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

Crepitus causing unsatisfied result to patients after posterior stabilized total knee arthroplasty. Recent retrospective study demonstrated removal of hyperplastic synovium in distal quadriceps caused reduce of crepitus. However, this study has limitation of time gap exist between arms, different in observation time and bias caused by retrospective review. Thus aim of this study is that by randomized trial, verified hyperplastic synovium in distal quadriceps causing crepitus. Target enrolled patients in this study are scheduled to perform both total knee arthroplasty. Experimental group is randomized side (right or left) of knee, and control group is other side of knee. Both arms decided by randomized number table. Crepitus measured after 3mo, 6mo, 1year after surgical treatment
