초록

Patellar clunk syndrome after total knee arthroplasty is a complication that causes pain and poping or catching of patella. We experienced a case after mobile bearing total knee arthroplasty that medial synovial tissue was impinged between patella and femoral component and intra-articular fibrotic nodule of superior pole of patella was observed. Also, wear of Polyethylene were observed at anterio side. We resolved the patient symptom after excision of fibrotic nodule, synovectomy of medial synovial hypertrophy, and change of polyethylene. We report this case with literature review.
