Surgery to remove synovium in the quadriceps tendon to reduce knee crepitus after total knee replacement

Official title: Partial Synovectomy in Articular Side of Quadriceps Tendon Reduces Crepitus After Posterior Stabilized Total Knee Arthroplasty : a Randomized, Controlled Trial

Run by Gangnam Severance Hospital · NCT06129214 · Data updated 2026-11-12

This study is testing if removing a part of the tissue around the quadriceps tendon can help reduce the annoying popping or crackling sound in the knee after total knee replacement surgery.

Is this trial a fit for you?

Likely a good fit

Ideal candidates for this study are patients scheduled for total knee arthroplasty who do not require patella resurfacing.

Probably not a fit

Patients with significant radiological or physiological variance between knees or those who experience unexpected complications may not benefit from this study.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This clinical trial aims to evaluate the effectiveness of partial synovectomy in the distal quadriceps tendon to reduce crepitus in patients undergoing total knee arthroplasty. Participants will be randomly assigned to either an experimental group, which will undergo synovium removal, or a control group, which will not. The study will measure crepitus levels at 3 months, 6 months, and 1 year post-surgery using various scoring systems. Radiologic and physiological evaluations will be conducted prior to surgery to ensure comparability between the two groups.

Why it matters

Potential benefit: If successful, this approach could significantly improve patient satisfaction and outcomes following total knee arthroplasty by reducing crepitus.

How similar studies have gone: While similar approaches have been explored, this specific randomized trial design focusing on synovium removal in the quadriceps tendon is relatively novel.
