Lengthening of Hamstring Tendons in Knee Flexion Contractures
Contractures of joints are usual sequelae of hemophilic arthropathy. These contractures result from a combination of recurrent hemarthroses which cause fibroblastic proliferation of the capsule, progressive arthropathy, and extraarticular intramuscular bleeding episodes leading to fibrosis. Hypertrophied synovium promotes fibrillation and erosion of articular cartilage. Progressive fibrosis of synovium leads to pain, spasm, and shortening of muscles, resulting in joint contractures and restriction of joint motion .
