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.

Am J Sports Med 2022 Jun 20;50(7):1815-1822. Epub 2022 May 20.

Department of Orthopaedic Surgery, The Princess Grace Hospital, London, UK.

Background: A "Stener-like" lesion of the knee is defined as a distal avulsion of the superficial medial collateral ligament (sMCL) with interposition of the pes anserinus between the ligament and its tibial insertion-a displacement impeding anatomic healing. Because of the scarcity of these injuries, the literature is limited to case reports and small case series.

Purpose: To assess the effect of surgical repair of acute Stener-like lesions of the sMCL on the following outcomes: return to preinjury level of sporting function; time to return to preinjury level of sporting function; functional performance; injury recurrence; and any other complications.

Tibial Avulsion with Intra-Articular Entrapment of Medial Collateral Ligament with Posterior Cruciate Ligament Tear with Posterior Root Medial Meniscus Tear: A Case Report of an Unusual Injury Triad.

J Orthop Case Rep 2021 Aug;11(8):28-32

Department of Orthopaedics, Dr. DY Patil Medical College and Hospital, Pune. Maharashtra, India.

Introduction: The medial collateral ligament (MCL) is the most commonly injured ligament of the knee joint; however, its displacement into the medial knee compartment is rare. Traumatic posterior root of medial meniscus (PRMM) tears are commonly found in high-grade injuries involving anterior cruciate ligament (ACL) or posterior cruciate ligament (PCL) tears along with MCL tears. Diagnosis of these injuries can be made by a preoperative magnetic resonance imaging (MRI), but they can be missed at times due to severe soft-tissue swelling in the acute phase. Read More
