Summary
Patellar tendinopathy (PT) is an overuse injury associated with loading activities, and popular among basketball and volleyball players. Although altered biomechanical characteristics during landing has been suggested as one of the risk factors for the development of PT, previous evidence failed to show the link between the sagittal plane biomechanics of the hip and knee joint and PT; and little was known about the frontal and horizontal plane biomechanics in athletes with PT. While other factors such as motor control or muscle activation also have not been explored fully. The purpose of this study is to compare hip motor control and biomechanical characteristics of the hip and knee joint during landing in athletes with and without symptomatic PT.
