[Single-compartment arthroplasty of the knee using the Marmor-Cartier method. Apropos of a series of 100 cases].

100 unicompartmental knee prosthesis type Marmor-Cartier with 86 replacements of the medial compartment have been followed for a period of 5 to 15 years. Contrary to the reaxation osteotomies, a moderate hypocorrection about 3 to 5 degrees has to be respected in unicompartmental knee replacement. The two major complications are degradation of the contralateral compartment due to hypercorrection; and loosening of the tibial plateau due to hypocorrection over 5 degrees or anterior laxity or convex side laxity or misalignment of the prosthetic device. The unicompartmental knee arthroplasty is a trustful surgical procedure as long as precise indications for this method and a rigorous surgical technique are respected.
