With improved manufacturing and machining of total joint arthroplasty components, mechanical failure is likely to be reduced in vivo in modern total knee replacement. Although rare, there are clearly certain components and clinical situations that may result in higher risk of component (femoral and tibial) fracture, hinge knee prosthesis fracture, tibial post fracture in posterior-stabilized total knee arthroplasty, as well as polyethylene dislocation. With continued adherence to arthroplasty principles of soft-tissue balancing, joint line restoration, and subsequent placement of the device in the optimal position mechanical complications may be minimized.
