The medial patellar plica syndrome.

A retrospective review of all patients diagnosed at arthroscopy as having a medial patellar plica with no other intraarticular pathology was conducted. Characteristic clinical findings, including pseudolocking, were identified. The clinical response of 68 patients (78 knees) to shelf resection was noted at 3 and 6 months. The 6-month review demonstrated 60% to be totally relieved of their preoperative pain and 31% with occasional discomfort, but capable of full activities. Three patients were graded with poor results (4%) due to limitations in their work and sports, and four patients were lost to followup. The overall good and excellent results totalled 91%. No surgical complications, infections, or wound dehiscences were noted.
