Tricon-M uncemented total knee arthroplasty. A review of 96 knees followed for longer than 2 years.
Ninety-six uncemented total knee arthroplasties done using the Tricon-M prosthesis were followed for longer than 2 years. The implant has a multilevel porous surface to facilitate biologic ingrowth and flanged polyethylene pegs for immediate fixation. Each patient was matched for age, body habitus, and diagnosis to a patient with a cemented total knee arthroplasty. There was no statistical difference between the matched pairs as related to pain, eventual range of motion, stability, or patient satisfaction; the uncemented group did as well clinically as the cemented group. Subsidence of the tibial component was noted in cases of obese patients taking systemic corticosteroids and in whom there was inadequate coverage of the cut tibial plateau surface. The mean 2-year Hospital for Special Surgery rating score was 81 in the osteoarthritis group and 83 in the rheumatoid arthritis group.
