Displaced Bucket-handle Meniscus Tear After Total Knee Arthroplasty: A Case Report

A 71-year-old woman presented with acute onset left knee pain and decreased range of motion (ROM) 1.5 years after total knee arthroplasty (TKA) at an outside institution. She underwent arthroscopic lysis of adhesions and manipulation under anesthesia. Intraoperatively, a displaced bucket-handle tear of the lateral meniscus was encountered and excised. At 12-month follow-up, clinical outcomes and ROM were markedly improved. The persistence of meniscus tissue after TKA is rare and should be considered as a possibility for pain and decreased ROM after TKA. This case highlights the value of meticulous removal of meniscus tissue during primary arthroplasty.
