The strength of the menisci of the knee as it relates to their fine structure
TLDR
The orientation of collagen fibres of the menisci of the knee has been demonstrated by polarised light microscopy and the tensile strength of theMeniscus is similar to that of articular cartilage.Abstract:
1. The orientation of collagen fibres of the menisci of the knee has been demonstrated by polarised light microscopy. 2. As might be supposed from its fibre structure, the ultimate tensile strength of the meniscal tissue is dependent upon the axis of loading. 3. The tensile strength of the meniscus is similar to that of articular cartilage.read more

Material properties and structure-function relationships in the menisci.
TL;DR: The menisci serve several important biomechanical functions in the knee: distribute stresses over a broad area of articular cartilage, absorb shocks during dynamic loading, and probably assist in joint lubrication.

TL;DR: Some principles which might guide the design of knee prostheses are deduced and it is shown that current designs transgress some of these principles.

TL;DR: This study highlights the importance of an intact and functioning meniscus in patients with symptomatic knee OA, since the findings demonstrate that loss of this function has important consequences for cartilage loss.

Karola Messner,Jizong Gao +1 more
TL;DR: There is no proof that replacement of the meniscus with an allograft can reestablish some of the important meniscal functions, and thereby prevent or reduce the development of osteoarthrosis which is common after meniscectomy.
Journal ArticleDOI
Homologous meniscus transplantation. Experimental and clinical results.
TL;DR: The increase in severe ligament injuries of the knee has led to consideration of the need for meniscal transplantation in reconstructive operations for chronic rotational instability, and both types of transplanted menisci, lyophilised and deep frozen, decreased in size.

Knee joint changes after meniscectomy
TL;DR: It seems likely that narrowing of the joint space will predispose to early degenerative changes, but a connection between these appearances and later osteoarthritis is not yet established and is too indefinite to justify clinical deductions.

The pattern of ageing of the articular cartilage of the elbow joint
J. W. Goodfellow,Peter Bullough +1 more
TL;DR: Evidence is presented that the almost inevitable degeneration of the radio-humeral joint in old age is related to the combination of rotation and hinge movements that occur at that joint.

The significance of the fine structure of articular cartilage
Peter Bullough,John Goodfellow +1 more
TL;DR: The fine structure of articular cartilage, as demonstrated by polarised light microscopy and electron microscopy, is related to the gross anatomy and to the naked eye changes of chondromalacia and fibrillation.

Tensile Properties of Articular Cartilage
TL;DR: Electron microscopy studies show that the collagen fibres near the articular surface are predominantly parallel to the surface; viewed perpendicularly to thesurface, they also show a dominant orientation which varies systematically over the whole joint surface.
