[Rehabilitation guidelines after total knee arthroplasty].

Rehabilitation programs after total knee arthroplasty vary as much as do the surgical procedures employed. The postoperative range of motion of the knee is considered to be one of the primary indicators of the success of arthroplasty surgery. Protocols focusing on improving range of motion have been widely investigated: the end result does not seem to depend on using specific devices or exercises. There are no prospective randomized clinical trials evaluating the differences in outcome after total knee arthroplasty between patients following different rehabilitation programs. What are the needs of the patient after this surgery? Rehabilitation should focus on physical and functional limitations, and guidance of the patient during this process is important. The patient follows an individual program comprising a sensorimotor progression in weight-bearing positions to allow for improved functional knee stabilization. In knee osteoarthritis, and also after total knee arthroplasty, the neuromuscular system undergoes various adaptations during gait and other activities. Because of this, rehabilitation should not attempt to achieve hypothetical norms, but to help the patient in the motor learning process of acquiring improved motion patterns and stabilization strategies.
