Description

The mechanisms causing ACL injuries in typical indoor sports are to date not known, although several hypotheses exist. A major problem is to find an objective way to perform the analyses, and so far a common method has been simply looking on videotapes of the injuries. Although much insight can be gained this way, it is hard to determine a good estimate of the involved joint motions, and even more so when it comes to the involved forces.

 

The purpose of this study is therefore to obtain estimates of the involved kinematics and kinetics involved in serious knee injuries in European team handball in order to describe injury mechanisms. Videos of ACL injury situations have been collected retrospectively and prospectively. At present we have about 35 videos in our archive. These videos are digitised, and treated and used as input for the model based image-matching method described in study 1. Based on these variables, a classification and description of the injury situations will be performed. These motion patterns will also have the potential to be used as input for forward dynamics simulations.

If we can reliably establish good estimates of the involved dynamics of the non-contact ACL injury situations, the potential for developing prevention strategies will be considerably improved. Together with the (probably more accurate) estimates of the involved dynamics in non-injury situations (study 2) and possibly forward simulations, we will hopefully take a step towards identifying the external (the effect of whole body motion, footwear-shoe interface, or other equipment) and internal causes (mechanical properties of the joint structures, etc.) of non-contact ACL injuries.
