![]() The terms posterior-substituting and posterior-stabilized have been used interchangeably for many years. The surgical technique and clinical results will then be reviewed. This chapter will first address the time line and progression of posterior-substituting components, from the earliest years to the currently available designs. 7Īn understanding of the history behind the current posterior-substituting prostheses on the market, key design concepts, important surgical principles and techniques will aid surgeons in providing well-functioning, durable, total knee replacements. 4, 16, 37 Furthermore, these surgeons believe that it is difficult to balance the PCL appropriately while maintaining its functional integrity and ability to accomplish near-normal femoral rollback. ![]() Today, surgeons that prefer this principle and technique over cruciate retention believe that the anterior and posterior cruciate ligaments (ACL, PCL) are histologically abnormal and therefore compromised in arthritic knees. Posterior cruciate substitution in total knee arthroplasty gathered momentum and popularity as the pioneering surgeons and design teams improved on their prototypes.
