The medial plica of the knee is a thin inward fold of synovium which is quite often found during arthroscopic surgery, especially in adolescents. Its exact presence is a subject of wide discussion, and incidence reports ranging from 21% to even 95%.

The purpose of this study was to evaluate the long-term results of arthroscopic resection of medial plica in adolescents and find the main symptoms in plica syndrome of a successful arthroscopic plica resection.

Material and methods:
Patients with hypertrophic medial plica were divided into 2 main groups, A and B. Group A (n = 26) suffered from pain associated with popping and clicking, catching, pseudo-locking and snapping. Group B (n = 23) suffered from pain only. Functional outcome indices (orthopaedic Tegner, Lysholm, and IKDC scores) were evaluated during this study.

Results and discussion:
Considerably better postoperative results were obtained for the patients of group A (Tegner score 8, Lysholm score 90, IKDC 90) vs. patients of group B (Tegner score 6, Lysholm score 68, IKDC score 68).

Only anteromedial knee pain with popping, clicking, catching, pseudo-locking and snapping should be interpreted as a medial plica syndrome that will benefit from arthroscopic resection.
