Gonarthritis

The study is designed as a prospective, observational, mid-term, multi-center follow-up study. It is planned to include 150 patients from 4 different study centres in Germany.

This study aims to investigate the effects of fatigue induced by isokinetic exercise on passive and active joint position sense in postmenopausal women diagnosed with knee osteoarthritis (gonarthrosis). A healthy control group matched for age and sex will also be included for comparative analysis. Participants will undergo proprioceptive assessments before and after an isokinetic fatigue protocol. We hypothesize that (1) fatigue will impair both passive and active joint position sense in patients with gonarthrosis, (2) active joint position sense will be more affected than passive sense, and (3) the deterioration in proprioception will be greater in the gonarthrosis group compared to healthy controls.
