This review summarizes published literature that reports on clinical studies and/or randomized controlled trials from 1989 to end 2009 regarding the clinical performance history of several designs / brands of an all-polyethylene (AP) Tibial component used as part of a primary cemented Total Knee System implanted using established Total Knee Arthroplasty procedures. From the mid 1970’s knee systems for replacement of knees diagnosed with osteoarthritis, rheumatoid (inflammatory) arthritis, osteonecrosis, avascular necrosis and other degenerative joint conditions used a plastic tibial component articulating on a chrome cobalt femoral component. Resurfacing of the patella if required also used a plastic artificial patella button attached surgically with PMMA bone cement. Projections of increase in TKA of +600% increase in annual surgeries over the next 15 years has focused significant interest in reconsideration of using this style tibial component in the growing elderly population.
