Choosing Your Implant: Cemented, Tricompartmental, and Posterior Stabilized

Cemented, posterior-stabilized, tricompartmental implants have yielded excellent relief of pain and are applicable to almost all clinical situations. The complications and revision rates after routine patellar resurfacing are less than those seen without such resurfacing. Cine fluoroscopic studies have shown that they restore a more normal kinematic pattern than do posterior cruciate ligament–retaining implants and have a low rate of radiographic and/or clinical loosening when followed up through 15 years after surgery. Latest posterior stabilized designs can allow a higher degree of flexion than seen in any other combination of implant designs. It is for all these reasons that the author feels that this method of performing a knee arthroplasty is the gold standard.
