Arthroscopic Transosseous Repair of a Medial Meniscal Posterior-Root Tear.

JBJS Essent Surg Tech 2021 Oct-Dec;11(4). Epub 2021 Oct 7.

Department of Orthopedic Surgery, University of Minnesota, Minneapolis, Minnesota.

Meniscal root tears are soft-tissue and/or osseous injuries characterized by an avulsion of, or tear within 1 cm of, the native meniscal insertion. These injuries account for 10% to 21% of all meniscal tears, affecting nearly 100,000 patients annually. Medial meniscal posterior-root tears (MMPRTs) expose the tibiofemoral joint to supraphysiologic contact pressure, decreased contact area, and altered knee kinematics similar to a total meniscectomy.

A Biomechanical Comparison of the LaPrade Technique Versus a Novel Technique for Reconstruction of Medial-Sided Knee Injuries.

Am J Sports Med 2022 Jul 23;50(8):2083-2092. Epub 2022 May 23.

Department of Orthopaedics & Rehabilitation, University of New Mexico, Albuquerque, New Mexico, USA.

Background: Medial-sided knee injuries can lead to symptomatic valgus laxity or anteromedial rotatory instability and may require surgery, particularly in the setting of cruciate tears and tibial-sided medial collateral ligament (MCL) avulsions. The LaPrade (LP) technique utilizes 2 free grafts to reconstruct the superficial MCL (sMCL) and the posterior oblique ligament (POL). An alternative MCL reconstruction devised by the senior author comprises an anatomic single-bundle reconstruction using a free graft to reconstruct the sMCL with advancement and imbrication of the posteromedial capsule/POL (MCL anatomic reconstruction with capsular imbrication [MARCI] technique).
