The evolution of patellofemoral prosthetic design in total knee arthroplasty: how far have we come?

[摘要] Total knee arthroplasty (TKA) is generally described as a successful, cost-effective treatment for patients with end-stage arthritis of the knee,1–3 and it certainly is for 80% of patients.4,5 Since the innovations of the early 1970s, considerable advances have been made in terms of component design, peri-operative care, alignment strategies, surgical approaches, and, more recently, the use of advanced technologies such as computer navigation and robotic-assisted surgery to improve patient outcomes.6–11 The patellofemoral part of TKA, however, has a history of neglect despite the patellofemoral articulation being an important aspect of TKA that has a profound impact on outcome and may be a composite indicator for the overall success of the procedure.12 During this review, we will outline the evolution of design of the patellofemoral part of TKA and highlight the areas in much need of further research.
