[Biomechanical aspects of human joints].
The value of biomechanical studies of human joints is illustrated. The investigation of stiffness of joints has suggested that subjective stiffness is more likely to be related to limitation of movement of a joint than to increased physical stiffness. A knee analyser has been constructed to measure ligamentous and meniscal damage. Ligament replacement has been successfully achieved in the pig and in man by using a woven polyester tube. The load-bearing function of the menisci has been clearly demonstrated, explaining a relationship found in studies of parachutists and physical education teachers between meniscectomy and osteoarthrosis of the knee. The biomechanical reasons for a partial meniscectomy in the treatment of a bucket-handle tear have been shown. Support for the Leeds biomechanical hypothesis for the development of osteoarthrosis has been provided from mechanical studies of cartilage at the patello-femoral joint and at the ankle.
