Histological Evaluation Of Articular Cartilage Damage Following Radiofrequency Chondroplasty

Histopomorphic Evaluation of Radiofrequency Mediated Débridement Chondroplasty

The use of radiofrequency devices has become widespread for surgical ablation procedures. When ablation devices have been deployed in treatment settings requiring tissue preservation like débridement chondroplasty, adoption has been limited due to the collateral damage caused by these devices in healthy tissue surrounding the treatment site. Ex vivo radiofrequency mediated débridement chondropl...

Biomechanical and histological evaluation of hydrogel implants in articular cartilage.

We evaluated the mechanical behavior of the repaired surfaces of defective articular cartilage in the intercondylar region of the rat femur after a hydrogel graft implant. The results were compared to those for the adjacent normal articular cartilage and for control surfaces where the defects remained empty. Hydrogel synthesized by blending poly(2-hydroxyethyl methacrylate) and poly(methyl meth...

Complex and elementary histological scoring systems for articular cartilage repair.

The repair of articular cartilage defects is increasingly moving into the focus of experimental and clinical investigations. Histological analysis is the gold standard for a valid and objective evaluation of cartilaginous repair tissue and predominantly relies on the use of established scoring systems. In the past three decades, numerous elementary and complex scoring systems have been describe...

Electrokinetic evaluation of human articular cartilage

Causes of mechanically induced collagen damage in articular cartilage.

Osteoarthritis (OA) is a multifactorial disease, associated with articular cartilage degeneration and eventually joint destruction. The phases of the disease have been described in detail, and mechanical factors play an important role in the initiation of OA, but many questions remain about its etiology. Swelling of cartilage, one of the earliest signs of damage, is proportional to the amount o...
