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 […]

Editorial Commentary: Comparing Medial and Lateral Meniscal Root Tears Is Like Comparing Apples and Oranges


Authors:

Robert F. LaPrade, M.D., Ph.D., Nicholas N. DePhillipo, M.S., A.T.C., O.T.C., and Christopher M. Larson, M.D.

Abstract:

The importance of treating meniscal root tears has been increasingly recognized, and surgeons have to make conscious decisions routinely regarding repair for select patients. The clinical and patient demographic differences between medial and lateral meniscal root tears are important […]

Nonanatomic Placement of Posteromedial Meniscal Root Repairs: A Finite Element Study


Authors

B. Steineman, R. LaPrade, T.L. Haut Donahue

Abstract

Nonanatomic placement of posteromedial meniscal root repairs alters knee mechanics; however, little is known about how the position and magnitude of misplacement affect knee mechanics. Finite element knee models were developed to assess changes in cartilage and meniscus mechanics for anatomic and various nonanatomic repairs with respect to […]

Type II Medial Meniscus Root Repair With Peripheral Release for Addressing Meniscal Extrusion


Abstract

Medial meniscal root tears are often disabling injuries that can occur in isolation during low-velocity, deep
knee flexion maneuvers in middle-aged patients. The most common meniscal root tear pattern is a radial tear near the
root attachment (type II). Root tears are often associated with meniscal extrusion, identified on magnetic resonance
imaging. Relocation of the meniscal root […]

Influence of Medial Meniscus Bucket-Handle Repair in Setting of Anterior Cruciate Ligament Reconstruction on Tibiofemoral Contact Mechanics: A Biomechanical Study


Purpose:

To compare the impact of an inside-out repair versus meniscectomy of a medial meniscus bucket-handle tear in restoring native contact areas and pressures across the tibial plateaus in the setting of an anterior cruciate ligament (ACL) reconstruction (ACLR).

Methods:

Ten fresh-frozen cadaveric knees were tested in 6 knee conditions (1: intact; 2: ACL torn and bucket-handle […]

Clinical Outcomes of Inside-Out Meniscal Repair According to Anatomic Zone of the Meniscal Tear


Background:

There is significant discrepancy in the reported vascularity within the meniscus, and a progressively diminishing blood supply may indicate a differential healing capacity of tears that is dependent on the affected meniscal zone.

Purpose:

To examine the outcomes after inside-out meniscal repair in all 3 meniscal vascularity zones.

Study Design:

Cohort study; Level of evidence, 3.

Methods:

Patients were included […]

Utilization of Transtibial Centralization Suture Best Minimizes Extrusion and Restores Tibiofemoral Contact Mechanics for Anatomic Medial Meniscal Root Repairs in a Cadaveric Model


Background

Although posterior medial meniscal root (PMMR) repairs are often successful, postoperative meniscal extrusion after a root repair has been identified as a potential clinical problem.

Purpose/Hypothesis

The purpose was to quantitatively evaluate the tibiofemoral contact mechanics and extent of meniscal extrusion after a PMMR repair. It was hypothesized that the addition of a centralization suture (into […]

Quantitative and Qualitative Assessment of Posterolateral Meniscal Anatomy: Defining the Popliteal Hiatus, Popliteomeniscal Fascicles, and the Lateral Meniscotibial Ligament


Background:

Surgical treatment of lateral meniscal tears can be challenging due to the greater mobility of the lateral meniscus, thin capsule, and management of the popliteal hiatus. There has been a lack of quantitative assessments of the structural attachments to the posterior horn of the lateral meniscus (PHLM) to guide repairs.

Purpose:

To qualitatively and quantitatively describe […]

Biomechanical Comparison of Vertical Mattress and Cross-stitch Suture Techniques and Single- and Double-Row Configurations for the Treatment of Bucket-Handle Medial Meniscal Tears


Background:

Given the variety of suturing techniques for bucket-handle meniscal repair, it is important to assess which suturing technique best restores native biomechanics.

Purpose/Hypothesis:

To biomechanically compare vertical mattress and cross-stitch suture techniques, in single- and double-row configurations, in their ability to restore native knee kinematics in a bucket-handle medial meniscal tear model. The hypothesis was that […]
