Authors:

Robert F. LaPrade​, Edward R. Floyd, Gregory B. Carlson, Gilbert Moatshe, Jorge Chahla, Jill K. Monson

Abstract:

In this review article, the authors describe the most current knowledge surrounding meniscal root tears with a primary focus on diagnosis, management, and implications for the health of the knee joint. Historically overlooked or treated with meniscectomy, meniscal root […]

The Posterolateral Corner: Explanations and Outcomes


Authors:

Robert F. LaPrade, Edward R. Floyd, Gregory B. Carlson, Gilbert Moatshe, Jorge Chahla, Jill Monson

Abstract:

In this review, we examine the current understanding of posterolateral corner (PLC) injuries and treatment methods. We discuss the anatomy of the major structures of the PLC and the biomechanics of how these structures function together as a unit. The […]

Anterior Cruciate Ligament Reconstruction Failure and Revision Surgery: Current Concepts


Authors:

Santiago Pache, Juan Del Castillo, MD, Gilbert Moatshe, MD, Robert F LaPrade, MD

Abstract:

Anterior cruciate ligament reconstruction (ACLR) is one of the most commonly performed procedures in orthopaedic sports medicine. Despite developments in understanding the anatomy and biomechanics of the knee joint, a fairly large subset of patients has ACLR […]

Peripheral Stabilization Suture to Address Meniscal Extrusion in a Revision Meniscal Root Repair: Surgical Technique and Rehabilitation Protocol


Authors:

Robert S. Dean B.S, Nicholas N. DePhillipo M.S., A.T.C., O.T.C., Jill K. Monson P.T., O.C.S, Robert F. LaPrade, M.D., Ph.D.

Abstract:

Meniscal root tears are an increasingly recognized condition. These tears can cause the meniscus to become extruded outside the joint, which can diminish the biomechanical functionality of the meniscus. Anatomic repair of the meniscal root […]

Technique for Treatment of Subchondral Compression Fracture of the Lateral Femoral Condyle Associated With ACL Tear


Abstract:

Excessive knee pivoting that causes a complete anterior cruciate ligament (ACL) tear may result in a subchondral compression fracture on the lateral femoral condyle after impacting the lateral tibial condyle. Because this mechanism is similar to the humeral head that has an impact on the glenoid during an anterior shoulder dislocation, such an osteochondral […]

Medial Meniscus Root Repair in Patients With Open Physes


Abstract:

Meniscal root tears have become increasingly recognized in the past decade. Lateral meniscus root tears typically occur in active, younger patients who sustain acute anterior cruciate ligament tears. Conversely, medial meniscus root tears typically occur in isolation and affect middle-aged patients. However, recent reports have described the incidence of meniscal root tears occurring in […]
