Circumferential Meniscal Reconstruction Using the Semitendinosus Tendon for a Medial Meniscal Posterior Root Tear.

This article describes a surgical technique that addresses the limitations of existing approaches in managing meniscal extrusion after medial meniscal posterior root tear repair. Although traditional methods such as pullout repair and suture anchor repair are highly effective, they often struggle to adequately prevent meniscal extrusion, leading to suboptimal meniscal function restoration. Our method, which uses the semitendinosus tendon for circumferential joint capsule reinforcement, significantly reduces meniscal extrusion and enhances knee stability in patients with medial meniscal posterior root tears. Preliminary results suggest that this technique is superior to conventional methods in terms of preventing meniscal extrusion and restoring knee function.
