BACKGROUND A high degree of meniscal body extrusion on knee magnetic resonance imaging has been shown to be strongly associated with development of knee osteoarthritis. However, very little is known about meniscal position in the asymptomatic knee and its natural history. Hence our objective was to study meniscal body position and its change over 4 years in asymptomatic adults. METHODS Cohort...

The fibrocartilagenous knee menisci are situated between the femoral condyles and tibia plateau and are primarily anchored to the tibia by means of four attachments at the anterior and posterior horns. Strong fixation of meniscal attachments to the tibial plateau provide resistance to extruding forces of the meniscal body, allowing the menisci to assist in load transmission from the femur to th...

Recently, studies have emphasized the importance of anatomical placement of the lateral meniscal allograft to decrease postoperative extrusion. However, it is infeasible to identify the exact rotation of the allograft during transplantation. We present a patient who underwent a lateral meniscal transplantation using a wire for correct positioning of the allograft. The use of a wire intraoperati...

INTRODUCTION Meniscal tears are common debilitating injuries that can have dramatic consequences especially for young athletes. Healing of meniscal tears following surgical repair is essentially only feasible for tears within the peripheral, vascular, zone. By comparison, tears that occur within the inner, avascular, zone do not heal and most commonly are treated by excision. This in turn great...

From 1988 to 1990, eighty operations on eighty knees of seventy-nine patients with a clinical diagnosis of meniscal tear was entered into a prospective study. The clinical diagnosis was correct in 76% of patients. Excellent or good results were achieved in 90% of knees which had only meniscal lesions but dropped to 70.5% when other intraarticular pathologies coexisted with the meniscal lesions....

Once described as a muscle remnant, and therefore treated with disrespect, the meniscus is now known to be a vital structure within the knee. Minimal partial meniscectomy performed arthroscopically, or meniscal repair when practical, have become the standard treatments. In spite of the advancements in understanding meniscal function and its preservation, much remains to be studied. In the futur...

The meniscus plays a vital role in knee biomechanics, and its physical absence or functional incompetence (e.g., irreparable root or radial tear) leads to unacceptably high rates of joint degeneration in affected populations. Meniscal allograft transplantation has been used successfully to treat patients with postmeniscectomy syndrome, and there is early laboratory and radiographic evidence hin...

Background Meniscal and chondral lesions are commonly associated with anterior cruciate ligament (ACL) tears, and these lesions may play a role in patient outcomes after ACL reconstruction. Purpose To determine the effects of the presence and location of meniscal and chondral lesions at the time of ACL reconstruction on patient-reported outcomes at a minimum 2-year follow-up. Study Design C...

Meniscal cartilage tears are common and predispose to osteoarthritis (OA). Most occur in the avascular portion of the meniscus where current repair techniques usually fail. We described previously the use of undifferentiated autologous mesenchymal stem cells (MSCs) seeded onto a collagen scaffold (MSC/collagen-scaffold) to integrate meniscal tissues in vitro. Our objective was to translate this...

Meniscal injury in the dog is most commonly associated with cranial cruciate ligament (CrCL) insufficiency. The reported incidence varies from 33.2% to 77 %. In a recent study reporting a series of 1000 dogs treated for CrCL insufficiency, 33.2% of dogs presented with a meniscal tear diagnosed at the time of the first surgery. The sex distribution was 39.7% neutered males, 32.2% neutered female...
