Surgical treatment should be considered when the medial synovial plica covers part of the anterior aspect of the medial femoral condyle or ruptures, or when pain persists over a long period, thus reducing the potential for cartilage damage.Ĭartilage damage Impingement Medial femoral condyle Medial plica syndrome. The shape of the medial synovial plica and the duration between symptom onset and surgery were associated with cartilage damage. It can happen over time to people who run, ride a. Postoperative results were significantly better in the mild than in the severe group (P = 0.0017). One of the four folds, the medial plica, sometimes gets irritated from an injury or if you overuse your knee. The duration from onset to surgery was significantly longer in the severe than in the mild group (29.0 vs. Patellar ballottement tended to be more common in the severe than in the mild group (P = 0.059). The shapes of the medial synovial plica were types C and D of the Sakakibara classification in the severe group, and types A, B, and C in the mild group. Local findings, period from onset to surgery, arthroscopic findings, and postoperative results were compared in the two groups. They are found at the medial, superior and inferior margins of the patella 3 and may be asymptomatic in some individuals. Clinical Context Plicae are synovial tissue folds which are embryological in origin but may persist in some individuals. Subjects were divided into those with severe cartilage damage, defined as International Cartilage Research Society (ICRS) stage 2 or higher, and those with mild cartilage damage, defined as ICRS stage 1 or lower. Provocation of pain is indicative of an inflamed medial patellar plica. The study subjects included 44 patients with 57 knees arthroscopically diagnosed with medial plica syndrome. Occasionally, the medial patella plica can become thickened and trapped between the patella and the femur, causing painful clicking and locking. This study was designed to evaluate the characteristics of patients with medial plica syndrome and associated cartilage damage.
