[Hip and knee replacement and sport].
BACKGROUND
Knee or hip arthroplasty in the sportsman raise many problems including the possibility or to come back to sports activities, and the implants longevity. Unicompartimental prosthesis of the knee is a relatively preserving surgery whose results in the long run in particular for the sporting subject can be for some authors sometimes disappointing. Total knee arthroplasty remains more invasive but with functional results always compatible with some sports activities. The functional result depends much on the postoperative, plurifactorial flexion. Concerning the hip, the sportsman, more active and younger than the average population suffering from osteoarthritis suffer statically more of osteoarthritis. The contribution of the total hip prostheses without cement, anatomical even custom, and of the new couples of friction seems to allow a better longevity. In addition, the contribution of the mini-invasive techniques and the computer-assisted surgery seem techniques with a promising future.


METHODS
We present our experience with the unicompartimental arthroplasty, the postoperative flexion in the total knee prostheses and in the hip arthroplasty for the younger patient and the relations between these interventions and sports.


RESULTS
Many authors studied the possibilities of sporting recovery (standard of sport and level of practice). The majority of the activities can be taken again, by excluding the sports of team, of ball and the jogging. The contribution of the mini-invasive techniques seems to allow a faster recovery and the uncemented hip prostheses give good long-term results in the young and active patient.
