Incidence of Posteromedial Meniscocapsular Separation and the Biomechanical Implications on the Anterior Cruciate Ligament.

Purpose: To report the incidence of posterior medial meniscocapsular junction (PMCJ) separation in patients with anterior cruciate ligament (ACL) injury and to evaluate its biomechanical effect on the ACL.

Methods: Three hundred thirty-seven consecutive patients undergoing isolated primary ACL reconstruction were retrospectively analyzed for PMCJ lesion. Forty-four patients were identified with PMCJ lesion and studied.

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

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.

Lateral Patellofemoral Ligament: An Anatomic Study.

Background: Medial instability of the patellofemoral joint is a rare but known phenomenon that may result from an incompetent lateral patellofemoral ligament (LPFL). Surgical reconstruction of the LPFL has been described. However, anatomic details of the ligament have not been the subject of scrutiny.

Comparison of Time to Recurrence of Instability After Open and Arthroscopic Bankart Repair Techniques.

Background: The results of open and arthroscopic instability repairs have been shown to be equivalent in recent literature.

Purpose: To compare the time to recurrence (TTR) of instability and disease-specific outcome measures in patients undergoing open and arthroscopic Bankart repair.

Study Design: Cohort study; Level of evidence, 3.
