Selvan D, Santini AJA, Davidson JS, et al. - This study was intended to present the medium term survival analysis of an all-polyethylene tibia in a single series cohort of over 1000 knees. The medium term outcome was examined in 1,092 patients with an all-polyethylene tibial component in their total knee replacement. The outcomes of this research demonstrate that an all-polyethylene tibia in a total knee replacement has good outcome data, high patient satisfaction with good survivorship in the medium term, coupled with potential cost-saving advantages.
