Biomechanics of total knee replacement

Abstract

A critical review of widely used knee arthroplasty devices was presented by classifying them under the titles of hemi-arthroplasty devices, hinged prosthetic devices, duo-compartmental devices and uni-compartmental devices. This classification was followed by delineation of set of design criteria for total knee prosthesis to meet the principal goals of the knee arthroplasty. A report on the comparison of a geometric knee prosthesis with the natural knee was presented and it was concluded that during surgery the rotational alignment of the geometric prosthesis is much more critical than the translational alignment.
