Remobilization causes site‐specific cyst formation in immobilization‐induced knee cartilage degeneration in an immobilized rat model
An understanding of the articular cartilage degenerative process is necessary for the prevention and treatment of joint disease. The present study aimed to examine how long-term immobilization-induced cartilage degeneration is aggravated by remobilization. Sixty 8-week-old male Wistar rats were used in this study. The unilateral knee joint was immobilized using an external fixator for 8 weeks. ...
متن کاملNew herbal composition (OA-F2) protects cartilage degeneration in a rat model of collagenase induced osteoarthritis
BACKGROUND Prevalence of osteoarthritis (OA) is on rise on the global scale. At present there are no satisfactory pharmacological agents for treating OA. Our previous study showed that Sida cordifolia L. and Zingiber officinale Rosc. had protective effect on cartilage. Here, we describe the effect of OA-F2, a herbal formulation prepared using combination of these two plants in alleviating OA as...
متن کاملPathways of load-induced cartilage damage causing cartilage degeneration in the knee after meniscectomy.
Results of both clinical and animal studies show that meniscectomy often leads to osteoarthritic degenerative changes in articular cartilage. It is generally assumed that this process of cartilage degeneration is due to changes in mechanical loading after meniscectomy. It is, however, not known why and where this cartilage degeneration starts. Load induced cartilage damage is characterized as e...
متن کاملIntra-articular collagenase injection increases range of motion in a rat knee flexion contracture model
Objectives A knee joint contracture, a loss in passive range of motion (ROM), can be caused by prolonged immobility. In a rat knee immobilization flexion contracture model, the posterior capsule was shown to contribute to an irreversible limitation in ROM, and collagen pathways were identified as differentially expressed over the development of a contracture. Collagenases purified from Clostrid...
متن کاملEffect of pregnancy on joint contracture in the rat knee.
As there is evidence that ligamentous laxity is affected by the female hormones, we hypothesized that hormonal changes occurring during pregnancy could have a therapeutic role in preventing the development of a joint contracture. Knee joint contractures were created in pregnant and nonpregnant rats. After 2 wk of immobilization, the degree of contracture was measured with structural properties ...
