Total knee arthroplasty. Current clinical perspectives.

Cemented total knee arthroplasty (TKA) has evolved to be the gold standard to which other means of fixation should be compared. Though controversy still exists regarding retention or sacrifice of the posterior cruciate ligament, clinical experience and survivorship analysis supports the use of the posterior stabilized prosthesis. Improvements in implant design, surgical technique, bone preparation, and cement technique have made TKA a more predictable procedure. With these advances, infection presently appears to be the main cause of failure in cemented TKA.
