Clinical Trial Summary

The purpose of this trial is to define knee joint pathomechanics (KJPM) in the first 2 years after ACL reconstruction (ACLR) and relate these KJPM with changes in articular cartilage morphology and quality.


Clinical Trial Description

This research project is a longitudinal prospective study. The investigators aim to define the KJPM longitudinally in the first 2 years following ACLR. The investigators relate these KJPM, combined with the cumulative mechanical exposure, to changes in articular cartilage/joint surface morphology and quality. To investigate the loading pattern on the knee joint, daily activities like walking, running and climbing stairs will be performed by the participants. The overall goal of this research project is to investigate whether KJPM are related with early cartilage degeneration. This is a first major step towards reducing the risk for post-ACLR onset of Post-Traumatic Knee Osteoarthritis (PTOA). Two work packages (WP) can be separated, that each have a separate aim: WP1: The first aim of this WP (WP1.A) is to profile longitudinal changes in knee contact forces (KCFs) and knee contact pressure (KCP) distribution of the articular cartilage in the first 2 years following ACLR. Second, in WP1.B, the investigators will identify multivariate proxies of KCFs (and KCP) to improve clinical translation (for example by facilitating the development of prognostic tools for verifying KJPM in real life). WP2: the second aim is to establish the relationship between KJPM at different time points following ACLR and (changes in) articular cartilage morphology and quality (WP2.A). Furthermore, the investigators will compare the biomechanical profile of "fast PTOA progressors" with "fast non-traumatic early osteoarthritis progressors" (WP2.B). ;
