| Outline of Final Research Achievements |
Joint instability, such as abnormalities of mechanical stress, secondary to ACL injury is the most significant risk factors for osteoarthritis (OA).This study aimed to assess whether joint instability of knee following ligament injury is an independent risk factor for osteoarthritis of the knee joint.We hypothesized that providing biomechanical control following ACL injury may result in the inhibition of cartilage degradation in the articular cartilage.
In result, an important contribution of our study was in identifying factors that may delay progression of OA. Joint instability appears to contribute to the progression of articular cartilage degeneration independent of intra-articular conditions, and mechanical factors are independent risk factors for OA. Further studies are required to assess the relationship between the chemical and mechanical responses to injury in the pathogenesis of osteoarthritis.
