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 [...]
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 [...]
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 [...]
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 [...]
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 [...]
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 [...]
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 [...]
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, [...]
Biomechanical Comparison of 3 Novel Repair Techniques for Radial Tears of the Medial Meniscus
2019 AJSM Complete radial tears of the medial meniscus have been functionally described as being similar to a total meniscectomy, and they represent a challenging problem to treat. Without treatment, radial tears of the medial meniscus can lead [...]
The Role of Meniscal Tears in Spontaneous Osteonecrosis of the Knee
2017 AJSM Osteonecrosis of the knee is a debilitating disease that can progress to end-stage osteoarthritis. Spontaneous osteonecrosis of the knee (SONK or SPONK) is 1 of 3 categories that are used to substratify osteonecrosis, the other 2 [...]
Current Concepts Review: Meniscal Repair
The meniscus was once considered a functionless remnant of muscle that should be removed in its entirety at any sign of abnormality. Its role in load distribution, knee stability, and arthritis prevention has since been well established. The [...]

The purpose of this review was to summarize recent advances in the diagnosis and treatment of meniscus root tears. Over the past decade, meniscal root tears have become increasingly recognized as a significant source of pain and disability. [...]
Two-Tunnel Transtibial Repair of Radial Meniscus Tears Produces Comparable Results to Inside-Out Repair of Vertical Meniscus Tears
2017 AJSM Complete radial meniscus tears constitute a unique subset of meniscus injuries, resulting in disruption of the circumferential fibers and compromising their ability to with-stand hoop stresses. This results in decreased contact area and increased tibiofemoral contact [...]
