Abstract

Introduction:

• Posterior-stabilized (PS) TKA that sacrifice the cruciate ligaments improves pain and function in patients with advanced osteoarthritis.
• Patellar crepitus appears to be due to a spectrum of peripatellar fibrosynovial formations and is usually encountered after PS-TKA, which uniquely has an intercondylar box to accept the tibial post.
• Symptoms of patellar crepitus occur most commonly during terminal knee extension and occur usually from 3 to 9 months after PS-TKA, and in some cases, this phenomenon is symptomatic enough to warrant an arthroscopic procedure or open arthrotomy.
• The development of patellar crepitus after PS-TKA appears related to many factors such as femoral component design, surgical errors, increased postoperative knee flexion, and postoperative patellar baja, which are also responsible for patellar clunk syndrome.
