[Osteoarthrosis of the knee joint, a predictable consequence of meniscectomy in patients with angular deformity of the knee (author's transl)].
The load-bearing function of the menisci is now well established. Meniscectomy increases the load per unit area in the operated femorotibial compartment; this may result into accelerated wear and osteoarthrosis. This is even more likely to occur if meniscectomy is performed on a knee-joint which presents with a mechanical imbalance secondary to angular deformity in the frontal plane. Often, in such cases, the meniscus only displays secondary, degenerative changes, which do not justify meniscectomy. Through a better knowledge of the load-bearing function of the menisci and a more thorough clinical and roentgenological preoperative study in painful knees, undue meniscectomy could be avoided in a number of cases and the frequence of iatrogenic postmeniscectomy osteoarthrosis of the knee-joint could be reduced.
