walking with and without orthosis. The gait speed also showed no change. Rest pain showed a tendency towards reduction, but the initial value and the value 4 weeks after treatment did not differ. Stress pain reduced significantly after 4 weeks. The Likert scale showed an improvement in almost all patients but in one patient after a 4-week a worsening. A later arthroscopy showed a pronounced chondrocalcinosis in this certain patient, which explains the deterioration in this case. In the questionnaire KOOS all items showed significant differences. All items improved significantly. Conclusions: In summary, it can be stated that the orthosis significantly improved the subjective well-being of the patients after 4 weeks. Especially the reduction of stress pain shows the positive effect of the orthosis in patients with medial knee arthrosis. Improvement in many questionnaires items (pain, function, activities of daily living) were seen after 4 weeks of using the orthosis.
