Biomechanical diagnostics of knee joint condition in sport

This study involved 20 subjects divided in 3 groups (10 healthy subjects, 10 subjects with an ACL deficit). Kinematic and kinetic data were obtained through one-legged vertical jump, a motion which is very common in sport activities such as football. This motion comprises of concentric and eccentric component, meaning a preparation and performing the maximal take-off and finishing or stabilization in the knee joint, i.e. the landing, which is dominated by the work of one leg, the other one having no possible influence. The statistically significant difference between “ healthy” and “ ACL def.” groups is the angle of flexion and extension during take off. This means that the proprioceptive system follows what happens in the knee joint and in the case of a danger, sometimes even unnecessarily, it reduces the range of motions in the joint trying to decrease the load and the risk. This study could provide an insight into the functional status of the knee joint during training and rehabilitation process.
