PURPOSE: To evaluate whether different suture materials in meniscal repair may harm cartilage. METHODS: A preloaded linear friction testing setup including porcine knees with porcine cartilage, porcine meniscus, and different suture materials (braided nonabsorbable, absorbable monofilament) was used. Five groups with different tribological pairs were tested: cartilage on meniscus (control), cartilage on cartilage (control No. 2), and cartilage on different meniscus sutures (3 groups)...

The aim of the current study was to investigate the construction of the bone bridge and tibial plateau under arthroscopy during meniscal allograft transplantation, in order to simplify and enhance the accuracy of bone bridge fixation intraoperatively. A traction line passed through the attachment of the anterior and posterior horns of the superior meniscus to the bone bridge was used to pull the bone bridge into the knee joint cavity and fix the anteroposterior horns of the meniscus. At the junction of the body of the meniscus and the posterior and anterior horns of the meniscus, a traction line was created at the anterior and posterior 1/3 of the meniscus to pull and fix the meniscus...

BACKGROUND: Historically, radial meniscal tears were treated with partial or near-total meniscectomy, which usually resulted in poor outcomes. Radial meniscal tears function similar to a total meniscectomy and are challenging to treat. Repair of radial meniscal tears should be performed to prevent joint deterioration and the need for salvage procedures in the future. PURPOSE/HYPOTHESIS: The purpose was to compare 3 repair techniques for radial tears of the medial meniscus: the 2-tunnel, hybrid, and hybrid tunnel techniques...

The current understanding of the biomechanical role of the meniscus, in conjunction with the increasing efforts to achieve its preservation within the orthopaedic community during treatment of meniscal lesions, has prompted the development of different meniscal repair techniques. The outside-in technique is recommended for anterior horn and middle-segment meniscal tears and has been recognized as a low-cost procedure with a low incidence of complications. Diverse modifications of this technique have been published over the past decade...

Damage to the meniscal hoop structure results in loss of biomechanical function, which potentially leads to the extrusion of the meniscus from the weight bearing area. However, there have been no established, effective treatments for such injuries. The purpose of this study was to investigate the applicability of cell-seeded nanofibrous scaffolds to repair the damaged meniscal hoop structure along with the prevention of subsequent cartilage degeneration using a rabbit model. Meniscal radial defects (5 mm width) in the medial meniscus were treated by wrapping and suturing with either an aligned electrospun nanofibrous scaffold alone or a scaffold combined with a tissue engineered construct (TEC) derived from synovial mesenchymal stem cells (MSCs), with the scaffold fiber direction matching that of the meniscal circumferential fibers...

BACKGROUND: The effect of lateral meniscal posterior root tear and repair-commonly seen in clinical practice in the setting of anterior cruciate ligament (ACL) reconstruction-is not known. PURPOSE/HYPOTHESIS: This study evaluated the effect of tear and repair of the lateral meniscal posterior root on the biomechanics of the ACL-reconstructed knee. It was hypothesized that anterior tibial translation would increase under anterior loading and simulated pivot-shift loading with the root tear of the posterior lateral meniscus, while repair of the root tear would reduce it close to the noninjured state...

Horizontal meniscal tears are often treated by partial meniscectomy. Some clinical studies have shown successful repair. The purpose of this study was to show that axial loading causes less horizontal displacement in partial than in total horizontal lesions and that suture of those lesions prevents horizontal displacement. Forty menisci were tested : sutured partial horizontal lesions (ten), sutured total horizontal lesions (ten) and matched unsutured control groups (ten each). Samples were put in a custom made fixation device...

Meniscus allograft transplantation (MAT) has yielded excellent long-term functional outcomes when performed in properly indicated patients. When evaluating a patient for potential MAT, it is imperative to evaluate past medical history and past surgical procedures. The ideal MAT candidate is a chronologically and physiologically young patient (<50 years) with symptomatic meniscal deficiency. Existing pathology in the knee needs to be carefully considered and issues such as malalignment, cartilage defects, and/or ligamentous instability may require a staged or concomitant procedure...

Management of intrasubstance horizontal cleavage meniscal lesions of microtraumatic origin remains poorly defined in young patients. For grade 2 lesions resistant to conservative measures, the standard technique is debridement of the intrasubstance tear and open suture repair via a posteromedial approach. The objective of this Technical Note is to propose an arthroscopic alternative to this open technique, using an arthroscopic additional posteromedial portal. This technique facilitates an approach to the lesion via its peripheral portion without creating an iatrogenic lesion of the free edge of the meniscus, which is located in the white zone and thus exhibits limited vascularity...

Objective The etiology of osteochondritis dissecans (OCD) is still uncertain. Recently, it has been hypothesized that instability of the anterior horn of the meniscus is an important cause for the development of a nontraumatic OCD in adolescents with good results after surgical stabilization. This case series aims to evaluate the treatment results after meniscus stabilization in adults with nontraumatic OCD. Design Ten patients with magnetic resonance imaging (MRI)-confirmed OCD of the knee joint, meniscal instability, and closed epiphyseal plates were enrolled in this study...

Treatment of symptomatic meniscal tears continues to evolve as we improve our understanding of the biomechanical role of the meniscus and its long-term importance to the health of the knee joint. Suture repair of meniscal tears is challenging and continues to rise as we aim to preserve meniscal tissue. Outside-in meniscal suture techniques may involve using expensive equipment that is not readily available for immediate use in most operating rooms. Aware of the different techniques available, the authors describe a fast and reproducible technique that does not require the use of specific material or equipment...

In recent years there has been increased attention on preserving the menisci because they perform vital roles in maintaining knee joint homeostasis. The anterolateral (AL) meniscal root is particularly vulnerable during anterior cruciate ligament reconstruction. When the AL root is iatrogenically injured, it is imperative that it is repaired in a timely fashion to prevent early-onset osteoarthritis. In this article we outline our knotless suture anchor repair for AL root tears.

INTRODUCTION: Radial meniscus tears are seen in young patients, especially with anterior cruciate ligament ruptures. Repair of complete radial meniscus tear is necessary for the meniscus functions. The most important factor for success of the meniscus repair is primary stability, but it is still unknown which technique is ideal repair technique. AIM: We developed a new suture technique named Horizontal Butterfly (HB). In this novel technique the contact between meniscal tissue and suture is more than Horizontal Loop (HL) that routinely used today...

BACKGROUND: Previous studies have reported various healing rates (0%-100%) as evaluated by second-look arthroscopy after repair of medial meniscal root tears (MMRTs). Such variable results might provoke suspicion of the necessity for repair. Furthermore, the effect of meniscal healing on the clinical outcomes has not been reported. PURPOSE: To more precisely determine the healing rate of MMRTs repaired through the transseptal portal, which could provide objective visualization of the healed meniscus, and to identify the effect of meniscal healing on the clinical and radiological outcomes...
