Patellar clunk syndrome (PCS) is one of the intraarticular mechanical problems that generally occur three to eight months after a total knee arthroplasty (TKA) surgery. The prevalence of PCS was reported as 0-7.5 %, which varies due to the type of implants used.The cause of this clinical syndrome is thought to be the growth of a fibrous nodule on the inferior aspect of the quadriceps tendon near the superior pole of the patella. Early cyst resection with open surgical or arthroscopic procedures provides a dramatic improvement in symptoms.
