Total-Condylar Knee Arthroplasty

Chitranjan S. Ranawat This book describes the principles and tech This can be explained by the fact that knee niques of knee arthroplasty, with contri arthroplasty requires implantation of the butions by multiple authors. Most of the ex knee joint into the correct mechanical axis perience has been gained with the use of of the leg with soft tissue balance to provide total-condylar knee arthroplasty by the vari stability. The patellofemoral joint replace ous contributors. Other types of knee ment and its alignment in relation to the mechanical axis of the body are important implants discussed are unicondylar and pos for stability and fixation of the patella. In terior cruciate-preserving prostheses. For revision surgery, the Total-Condylar III the past 4 years the importance of thickness prosthesis is described. Controversial topics of high density polyethylene, bone prepara such as preservation of the posterior cruciate tion, and cement penetration into the can ligament, unicompartmental replacement cellous bone to achieve an optimal bone-ce arthroplasty, metal-backed component, po ment composite for a durable arthroplasty rous ingrowth, and patellofemoral joint re has been clarified. These modifications have placement are discussed at length. Compli improved the technique and quality of fixa cations of the operation are also included. tion of knee arthroplasty to such a level that The total-condylar knee, both because of it is safe to predict that knee arthroplasty design and surgical technique, has been the will be more durable than hip arthroplasty preferred implant for knee arthroplasty in as presently done [1].
