Abstract

Some reported bearing fractures are due to entrapment of the bearing between the femoral component and posterior edge of the tibial base plate in unstable meniscal –bearing design TKA. However, so far no cases of bearing fracture has been reported for the rotating platform or anteroposterior gliding designs of mobile bearing TKA. The authors describe two cases of polyethylene stress fracture after primary TKA using a cruciate-retaining floating platform mobile-bearing prosthesis (e.motion-FP, B.Braun-Aesculap, Tuttlingen, Germany), and includes a review of the pertinent literature and a discussion of possible fracture mechanisms.
