Load bearing analysis has been performed in cadaver knees after different types of inner meniscus resection in extension and in 30 degrees and 60 degrees flexion. Contact areas, mean and maximum pressure differences and load flow changes were measured in the medial and lateral compartment of the knee. The investigation led to following findings: After posterior meniscal tear the resection of the tear with marginal smoothing is followed by a minimum of parameter deviation. ⋯ At the medial site a decrease of the load bearing area and the pressure can be registered. In contrast to that there is an increase of these parameters at the lateral site. Consecutive osteoarthritis after medial meniscectomy is therefore interpreted not as a result of increased pressure but of a floating load bearing.
