Conclusions

Recent reports with up to 10-year clinical follow-up have demonstrated that cementless total knee arthroplasty can yield excellent results in young, active patients when sound implant design principles and surgical techniques are followed. intimate apposition of the prosthesis to host bone is achieved with instrumentation that allows precise bone resection, and by the routine application of morselized autogenous bone chips to the cut surfaces. Revision of cementless total knee components without porous-coated pegs, keels, or stems has proven to be bone-sparing, which is an important consideration in the younger patient who may outlive their prosthesis. The authors believe that cementless fixation is a superior alternative to cemented fixation for primary total knee arthroplasty in younger patients with higher functional demands and good bone stock.
