BACKGROUND Since the in vivo morphometric data on the menisci of the knee joint of Indian subjects are scarce, we hereby studied the width and thickness of the menisci using Magnetic Resonance Imaging (MRI) to establish standard dimensions of the normal medial and lateral meniscus as an aid to orthopaedic surgery. METHODS Eighty menisci from 40 knee joints were analysed in each of three regio...

A conventional description of the effect of meniscus friction is based on the concept of the dynamic contact angle u, which depends on the meniscus velocity V according to the Tanner law, u}V. However, recent high-resolution experiments on spontaneous uptake of wetting fluids by capillaries have questioned the universality of the Tanner law. We analyze a mechanism underlying the phenomenologica...

Not so long ago, the accepted treatment for meniscal tears was removal of the entire meniscus. Today, orthopedic surgeons are doing everything possible to save the meniscus, especially in young patients, in order to decrease the chance of the patient developing arthritis. This article discusses 2 techniques for treating a torn meniscus: repair and transplantation. It also describes those patien...

OBJECTIVE Studies on the biology of the human meniscus cell are scarce. The objective of our studies was to assess survival/proliferation of human meniscus cells in different culture conditions and to characterize the extracellular matrix (ECM) produced by these cells in these artificial environments. The composition of this ECM offers a variable to define the distinct meniscus cell phenotype. ...

BACKGROUND Meniscectomy will lead to articular cartilage degeneration in the long term. Therefore, the authors developed an implant to replace the native meniscus. HYPOTHESIS The porous polymer meniscus implant develops into a neomeniscus and protects the cartilage from degeneration. STUDY DESIGN Controlled laboratory study. METHODS In a dog model, a porous polymer scaffold with optimal p...

This study aimed to quantify the biomechanical properties of murine meniscus surface. Atomic forcemicroscopy (AFM)-based nanoindentation was performed on the central region, proximal side of meniscifrom 6to 24-week old male C57BL/6 mice using microspherical tips(RtipE5 mm) in PBS. A unique,linear correlation between indentation depth, D, and response force, F, was found on menis...

OBJECTIVE Evaluation of the biomechanical interaction between meniscus and cartilage in medial compartment knee osteoarthritis. METHODS The finite element method was used to simulate knee joint contact mechanics. Three knee models were created on the basis of knee geometry from the Open Knee project. We reduced the thickness of medial cartilages in the intact knee model by approximately 50% t...

Experimental work in animals (Walmsley and Bruce 1938) has shown that the menisci of the knee joint can regenerate after surgical removal. There have been several reports of regenerated cartilages in the human knee joint (Mandl 1929, M#{246}ller 1930, Fisher 1936, Bruce and Walmsley 1937). Smillie (1944) described the characteristics of the regenerated meniscus. It is in general appearance simi...

Background: Meniscus tissue is highly susceptible to injury and tears. As these are intrasynovial and lack cellularity, their healing potential is less. Any knowledge to the factors affecting the meniscal healing can help surgeons in treating meniscal injuries. Hypothesis: Patient age is a predictor of the healing of meniscus tissue. Study Design: Prospective study. Methods: Gross and histologi...

A prospective study to determine the accuracy of computed tomography (CT) for the diagnosis of dislocation of the temporomandibular joint (TMJ) meniscus was made by performing both CT and contrast arthrography on 18 joints suspected of meniscus dislocation. Arthrography rather than surgery was chosen as the quality standard for comparing CT findings, as not all patients undergoing the studies u...
