Debris of polyethylene tibial bearings have been recognized as a major cause for the onset of the cascade of biological events leading to osteolysis and loosening of prosthetic components after total knee arthroplasty. Since then, research has been focused on alternative bearing surfaces in order to minimize the amount and rate of polyethylene wear off and, in doing so, increasing the survivorship rate for knee arthroplasties. One such option is to have a mobile tibial bearing allowing more conformity and rotational self-alignment of the components, improving kinetics and kinematics of the prosthesis. The authors present a resumed but throughout and comprehensive review of the rationale, biomechanics fundamentals, indications, pitfalls, outcomes and complications for the use of mobile tibial bearings in total knee replacement. |
