Symptomatic medial synovial plica of the knee joint: an underestimated pathology in young patients

Introduction To prospectively evaluate the outcome of arthroscopic resection of a symptomatic medial plica in patients under 30 years with evaluating the influence of sports, knee trauma and plica type. Methods 35 consecutive patients (38 knees), mean age 16.2 ± 4.7 years (9–26 years), 28 females (73.7%) were prospectively included. Patients with any additional surgical procedures or cartilage lesions > ICRS grade I were excluded. The influence of trauma to the knee, level of sport and the morphologic plica type on the outcome was evaluated in addition to standard knee scores before and 20.1 ± 9.3 months (12–44 months) after surgery. Results The Knee Injury and Osteoarthritis Outcome Score improved significantly from 50.2 ± 19.1% (12.5–94.6) to 80.7 ± 15.3% (48.2–100; p
