摘要：Knee osteoarthritis represents one of the most frequent conditions in the elderly population. This condition affects the whole joint, having an important impact on the patient’s quality of life. In this study, we evaluate the effect that medical rehabilitation treatment has on ligament instability in patients with knee osteoarthritis. Material and method: we evaluate, using specific tests, the anterior, posterior, lateral and medial stability in patients that undergo rehabilitation treatment. Evaluations were done initially, at 6 months after the first admission and at 12 months after the first admission. We compare the results in order to evaluate the impact the complex therapies that are applied have. Results: in all cases, except posterior instability, there is a good effect in lowering the percentage of patients with positive tests after the first round of rehabilitation treatment. At six month after the second round of rehabilitation treatment (12-month evaluation) the results show a slight, non-statistically significant improvement over the 6-month evaluation.
