Patellar Clunk Syndrome: A Systematic Review of Risk Factors and Treatment
Risk factors for developing PCS include implant design, implant type, retained patella, patellar thickness, and higher postoperative flexion. Other risk factors were not supported by multiple studies. Arthroscopic treatment has strong evidence for improving functional outcomes in patients with symptomatic PCS.
