Purpose: A metaanalysis was performed to assess the outcomes following surgical intervention for medial knee plica.Materials and Methods: A literature search of Medline, EMBASE, CINAHL and Cochrane CENTRAL was performed using relevant key words. The primary outcome was patientreported postoperative scores of “good” and “excellent”. Metaanalyses were performed using a random effects model. Results: The literature search identified 731 articles. After removing duplicates and those not meeting the inclusion criteria, 12 articles reporting on a total of 643 knees were included for analysis, and of these, 7 articles including 235 knees were used for metaanalysis. The overall rate of good and excellent outcomes following surgery was estimated at 84.2% (95% confidence interval [CI], 72.8–91.4). In those cases that had nonsurgical therapy prior to surgery, the rate of good and excellent outcomes of surgery was estimated at 76.1% (95% CI, 60.1–87).Conclusions: Arthroscopic surgical management of symptomatic medial knee plica results in favourable outcomes. Our results suggest that arthroscopic surgical excision should be considered as a treatment modality in patients with pathological medial plica disease of the knee either as a firstline treatment or when symptoms have not responded to nonsurgical interventions.Level of Evidence: IV
