Total hip arthroplasty with the porous-coated anatomic (PCA) prosthesis: the femoral component

This paper reviews the clinical and roentgenographic results of 228 primary non-cemented porous-coated (PCA) total hip replacements after a follow-up time of at least 2 years. The overall clinical results in the current series were satisfactory with at least 84% excellent and good clinical results at 2 years as well as 5 years postoperatively. Although functional results showed no deterioration with time we remain concerned about the high rate of persisting midthigh pain, the progressive loss of bone in the proximal part of the femur and the further loosening of beads from the femoral component's porous coating.
