Methods of combining the correction of deformities of the knee with the use of the total condylar prosthesis. Study of post-operative stability.

(1) Our Total Condylar knee prosthesis can be adapted to cases of severe deformity, either varus or valgus, and to flexion contracture. (2) The technique of mobilization and sliding of the capsulo-ligamentous structures on the contracted side is necessary in cases with severe deformity. (3) After mobilization of the contracted structures it is necessary, before sectioning the bone, to distract the joint in flexion as well as extension in order to achieve stability both in the sagittal and frontal planes. (4) Despite the removal of the cruciate ligaments and capsulo-ligamentous slide, no significant residual instability was found in either plane.
