This study is intended as a review of 3Tesla (T) magnetic resonance (MR) imaging of the triangular fibrocartilage complex (TFCC). The recent advances in MR imaging, which includes high field strength magnets, multi-channel coils, and isotropic 3-dimensional (3D) sequences have enabled the visualization of precise TFCC anatomy with high spatial and contrast resolution. In addition to the routine...

Introduction The bony insertion of the anterior cruciate ligament (ACL) is comprised of four distinct zones: ligamentous tissue, noncalcified fibrocartilage, calcified fibrocartilage, and bone. This “enthesis” is responsible for effectively transmitting the forces from the elastic ligament to the stiff bone. Despite its well organized structure, the enthesis has limited vascularity and thereby ...

The lack of a fibrocartilage layer between graft and bone remains the leading cause of graft failure after anterior cruciate ligament (ACL) reconstruction. The objective of this study was to develop a gene-modified silk cable-reinforced chondroitin sulfate-hyaluronate acid-silk fibroin (CHS) hybrid scaffold for reconstructing the fibrocartilage layer. The scaffold was fabricated by lyophilizing...

Malunion of distal radius fracture is often complicated with shortening of the radius with disturbed radio- ulnar variance, frequently associated with lesions of triangular fibrocartilage complex and instability of the distal radioulnar joint. Positive ulnar variance may result in wrist pain located in ulnar part of the joint, limited ulnar deviation and forearm rotation with development of deg...

Knee meniscus fibrocartilage is frequently injured, resulting in approximately 1 million procedures annually in the US and Europe. Its near-avascularity contributes heavily to its inability to heal, and places it as a prime candidate for replacement through regenerative medicine. Here, we describe a novel approach to increase extracellular matrix organization, rather than content, in order to a...

The distribution oftype II collagen, considered to be characteristic ofcartilaginous tissues, was determined in various specialized cartilages of the mature pig. The tissues examined were: (1) fibrocartilage of the semilunar meniscus of the knee; (2) elastic cartilage of the external ear; (3) hyaline cartilage of (a) the synoviral joint, (b) the thyroid plate of the larynx, and (c) the nasal se...
