The meniscus is a fibrocartilaginous tissue uniquely adapted to enable load transmission in the knee. Although the meniscus was once considered a useless remnant of joint formation, removal of all or part of the meniscus initiates osteoarthritis. Surgical repair methods focus on fragment stabilization or biologic enhancement of healing. An alternative approach based on tissue-engineering princi...

Isolated popliteomeniscal fascicle tears are often unrecognized and misdiagnosed. Patients typically have vague symptoms and often-normal magnetic resonance imaging and physical examination findings. Isolated injuries are often misdiagnosed and mistreated, leading to delayed surgical treatment. Unrecognized tears can lead to continued disability, lateral meniscus tears, and chondral lesions. Ap...

BACKGROUND Longitudinal meniscus tears are commonly encountered in clinical practice. Meniscus repair devices have been previously tested and presented; however, prior studies have not evaluated repair construct designs head to head. This study compared a new-generation meniscus repair device, SpeedCinch, with a similar established device, Fast-Fix 360, and a parallel repair construct to a cros...

Introduction Meniscal tears are prevalent and poor intrinsic healing (especially in avascular zones) directs clinical treatment towards partial removal rather than repair. However, removal alters joint biomechanics and can lead to early osteoarthritis. As there are limited restorative strategies (e.g. replacement using allografts), methods to foster repair by promoting cell growth, extracellula...

INTRODUCTION The surgical repair of traumatic tears of the meniscus may enhance tissue remodeling, help to maintain the stability of the knee joint, and prevent osteoarthritic changes. After repair of the experimentally lacerated meniscus, treatment by intra-articular injections of hyaluronan (HA) has been shown to enhance meniscal remodeling [2]. HA treatment also appears to slow the degenerat...

To evaluate the operation skill and curative effect of Fast-fix system used in the arthroscopic meniscal repair. [Methods] A retrospective analysis was done in 32 patients who received in the arthroscopic meniscal repair by Fast-fix system. Among them , 12 were left knee, 20 were right knee, 9 were medial meniscus, and 23 were lateral meniscus. [Result] Average follow-up was 2 years and 6 month...

We report here on a new arthroscopic direct repair technique for a radial tear of the posterior root of the medial meniscus (PRMM) using a posterior trans-septal portal. Radial tears of the PRMM are commonly observed in the elderly population of Korea and Japan, and the life style of these people requires squatting and kneeling down in daily life. A radial tear of the PRMM results in the loss o...

Understanding the structure and function of the meniscus is critical to understanding its role in overall knee joint function. Injury to, or removal of, meniscal tissue may be associated with articular cartilage wear, knee instability, and, ultimately, the progression of osteoarthritis. While every effort is made for preserving and/or repairing damaged meniscal tissue, in some cases, the menisc...
