A Randomised RSA Study of Peri-Apatite HA coating of a Knee Prosthesis

摘要

Abstract: Fifty knees scheduled for a total knee prosthesis were randomized in two groups. Both groups had a noncemented fixation of the porous-coated implants but one group received a prosthesis with ceramic coating on the porous surface of the implant. The knees were evaluated with RSA technique regarding micromotion the first two years. There were less micromotion in the coated group. The results indicate that the technique for ceramic coating here studied provides a safe and stable fixation of the implants.
