Abstract: BACKGROUND: Of ankle sprains and ankle ligament injuries, nearly 85% involved the lateral collateral ligaments, and the mechanism of injury was ankle varus during plantar flexion. Between 20% and 40% of patients with acute lateral ankle sprains develop persistent pain and chronic lateral ankle instability, resulting in excessive translation and rotation of the talus, accelerated cartilage wear and joint degeneration. Key words: ankle lateral collateral ligament, ankle joint, finite element, biomechanics, anterior talofibular ligament, calcaneofibular ligament |
