Total knee prosthesis. Evolution of the principles and technique and initial results obtained with the total-condylar...

The principles and details of the surgical technique for the insertion of total knee prostheses are presented, in particular the methods of dealing with the soft tissues, the correction of deformities, and the sequence and details of making the bone sections. The authors deal in detail with the technical characteristics of their modification of the Total-Condylar prosthesis "with posterior stability" and discuss its advantages over the traditional design. The main advantages are increased range of movement and better functional capacity, stability, and distribution of load on the tibial component. No disadvantages have yet been encountered, so the authors recommend the use of this prosthesis in all cases, rather than only in selected cases.
