Anatomic Repair of Posteromedial Meniscocapsular Separation Using an All-Inside Technique

Abstract Separation of the posteromedial meniscocapsular junction (PMC) is a unique injury seen in patients with disruption of the anterior cruciate ligament. PMC tears may go unrecognized despite preoperative magnetic resonance imaging and diagnostic arthroscopy of the medial compartment. Unrepaired lesions may lead to persistent laxity of the knee after anterior cruciate ligament reconstruction. Inside-out repair techniques risk iatrogenic injury to the articular cartilage during needle passage and require dissection of the posteromedial knee for suture retrieval. Previous all-inside techniques have required specialized implants and repaired PMC lesions with direct visualization of the tear. The presented all-inside technique is an easily reproducible, cost-effective means to anatomically repair separation of the PMC. The technique provides the surgeon direct visualization and full arthroscopic access to the lesion, making repair technically easy and efficient.
