Acute Anterior Dislocation in a Total Knee Arthroplasty Patient With a History of Sarcoma Resection.

ABSTRACT: Dislocation after total knee arthroplasty (TKA) is a rare complication, and few cases of anterior dislocation have been reported. Furthermore, there are no reports of early postoperative dislocation. A 72-year-old woman who had previously undergone resection of the posterior thigh muscle group for liposarcoma of the thigh underwent TKA for knee osteoarthritis. However, anterior dislocation was observed at 1 week postoperatively. We considered that the cause of the early anterior dislocation was previous resection of the posterior soft tissues of the knee joint. This case is a rare report of early anterior postoperative dislocation after TKA.
