We have reviewed 25 total knee prosthesis (Endo-Model type, Waldemar-Link) performedin 23 patients with an age average of 69,5 years-old and a average follow-up of 32 months.The clinical assessment applied was the AAOS protocol including the parameters of: pain, ability to goup and down the stairs, to need of sticks, flexion and extension of the joint, before and after the operation.In the radiological study we have evaluated the correct alignment of the components in twoplanes A-P and L, and the periprosthetic lucencies. The results obtained have been satisfying in all thepatients with a diminution of the pain and better function of the joint. No deep infection was observedand the flexion was better in prosthesis with anterior deviation of the femoral rod in the lateral plane.
