BACKGROUND Meniscal allograft transplantation has become a viable surgical alternative for a select group of patients with deficient or irreparable menisci. Subjective results are encouraging; long-term success, durability, and safety of allograft meniscal transplantation are uncertain. PURPOSES To evaluate a novel hydrogel meniscal replacement implant in an ovine model and assess chondroprot...

Purpose The purpose of this study was to examine the incidence of lateral meniscal tears associated with lateral tibial plateau fractures and report the clinical outcomes of meniscal treatment with internal fixation of fractures. Materials and Methods All lateral tibial plateau fractures (Schatzker types II and III) in skeletally mature patients treated operatively at our institution between ...

Meniscal tears are the most common knee injuries and have a poor ability of healing. In the last few decades, several techniques have been increasingly used to optimize meniscal healing. Current research efforts of tissue engineering try to combine cell-based therapy, growth factors, gene therapy, and reabsorbable scaffolds to promote healing of meniscal defects. Preliminary studies did not all...

The bucket-handle meniscal tear is a specific type of meniscal injuries which has specific signs on MRI. An attached fragment displaced away from the meniscus with any type of tear causes bucket-handle tear of the meniscus. Magnetic resonance imaging (MRI) is the most commonly used diagnostic tool for meniscal injuries. We present a case of free medial meniscal fragment which mimics the disloca...

The rationale for meniscal repair is based on the importance of the meniscus in overall knee function and stability as well as the inferior results seen with meniscectomy. The high success rate usually seen with arthroscopic meniscal repair has made it the treatment of choice for peripheral meniscal tears. This study reviewed the records of patients who have failed meniscal repair surgery to ga...

Objective The primary objective of this study was to evaluate the mechanical properties of the Smith & Nephew ULTRA FAST-FIXTM Meniscal Repair System in a bovine meniscal model. The results were compared with the clinically successful FAST-FIX Meniscal Repair System. Compared to the FAST-FIX device, cyclic testing showed that meniscal repair using the ULTRA FAST-FIX device resulted in a signifi...

AIM The aim of this study was to assess whether significant meniscal extrusion of more than 3 mm or of even lesser degrees of extrusion could be considered significant. We also aimed to determine the morphology of tears that are most likely to be associated with significant extrusion. Study design and material. The study was done retrospectively on a group of 202 patients (157 males and 45 fema...

INTRODUCTION Interleukin-1 (IL-1) and tumor necrosis factor-α (TNF-α) are up-regulated in injured and osteoarthritic knee joints. IL-1 and TNF-α inhibit integrative meniscal repair; however, the mechanisms by which this inhibition occurs are not fully understood. Transforming growth factor-β1 (TGF-β1) increases meniscal cell proliferation and accumulation, and enhances integrative meniscal repa...

Meniscal tears are commonly associated with anterior cruciate ligament (ACL) injuries. A deficient medial meniscus results in knee instability and could lead to higher stress forces on the ACL reconstruction. Comparison of results in meniscectomy and meniscal repairs revealed worse clinical outcomes in meniscectomy, but higher re-operation rates in meniscal repairs. Our aim was to review the re...

introduction: scintigraphy has been considered as a useful tool in the assessment of meniscal tears. our objective was to assess the accuracy of single photon emission tomography (spect), using mri as the gold standard, in the diagnosis of meniscal tears. materials and methods: between january 2003 and february 2005, 45 patients were studied with spect and mri. results: the respective sensitivi...
