title: Medium term outcome of the LCS cementless posterior cruciate retaining total knee replacements. Follow up and survivorship study of 35 operated knees.
abstract: Mobile bearing knee replacement has been designed to provide an effective prosthetic tool for improving long-term survivorship. Although, its potential long-term superiority has not been proven, an alarming possibility of its early mechanical failure has been previously reported. In the present study on 27 patients with 35 replaced knees due to osteoarthritis, 97.1% of a 5-year survivorship of LCS mobile bearing cementless total knee prosthesis is reported. This high survival rate, with a satisfactory functional outcome at middle term follow-up has been achieved by following an optimal technique of implantation. Therefore, in the middle term this mobile bearing design of total knee replacement is no less effective than the conventional fixed bearing designs.
