Facteurs prédictifs de la qualité du contrôle postural et de sa compensation dans les pathologies traumatiques et dégénératives du genou

Abstract : The knee can suffer damage from either traumatic or degenerative pathology. Anterior cruciate ligament (ACL) injuries frequently occur, especially in activities that including rotational stresses. Degeneration of the articular cartilage of the knee can subsequently result in osteoarthritis. The aim of this study was to analyze the predictive factors of postural control and recovery in traumatic injuries and also in degenerative pathologies of the knee. The effects of an innovative rehabilitation protocol combining reduced conventional rehabilitation with aquatic rehabilitation were compared with conventional rehabilitation defined by the National French Health Authority on the kinetics of recovery of proprioceptive skills and functional improvement. Postural control and motor control using clinical tests were quantified in 67 patients with ACL surgery before and up to six months after surgery. The effects of meteorological parameters on postural control and pain in knee osteoarthritis were evaluated in 113 patients, using posturography and also a pain scale. Six months after knee ligament surgery, both groups attained the same quality of postural control. However, patients who followed the innovative protocol made more used of proprioceptive inputs compared to the group who underwent conventional rehabilitation who made more use of a compensation mechanism. In patients following the innovative protocol proprioception was improved two months after surgery compared to before surgery. Muscle strength was higher in patients who followed the innovative rehabilitation protocol at one, two and six months after surgery. One month after surgery, the walking distance traveled was higher in patients who underwent innovative rehabilitation than in patients who had undergone conventional rehabilitation. In patients with knee osteoarthritis, degradation of postural control was observed when atmospheric pressure and maximum humidity decreased during the morning and when atmospheric pressure decreased during the entire day. Increased pain was correlated with increased temperature in the morning and with increased temperature and humidity during the entire day. The environment in which evolves the subject (aquatic, climatic) thus has an influence on postural control performance. A better management in post-ligamentoplasty rehabilitation of the knee would reduce the need for compensation using the contralateral limb, by better use of somesthesia. This could prevent the occurrence of osteoarthritis and a contralateral ACL injury, which would also reduce costs to the society and health care
