Abstract
In cementless joint arthroplasty, the first goal is stabilisation of the prosthetic components, due to bone ingrowth. In the past, to achieve the best fixation, orthopaedic surgeons used osteoconductive materials (HA, TriCa-Ph). To accelerate the fixation process, we have developed an osteoinductive procedure with growth factors. A product created from cancellous bone (BMP’s), bone marrow (stem cells) and platelet-rich plasma (growth factors) is applied to the tri-dimensional fixation surface (spongiosametal) of the prosthesis. Since June 2003, we have treated 15 arthroplasties with this procedure (11 THA, four TKA). The average duration of clinical follow-up was 6 months (range from 2 to 9 months). In case of THA, the average Harris Hip Score was 96 (Range from 91 to 100). In case of TKA, the average of HSS scoring was 90 (range from 85 to 100). The radiographic examinations were good. DEXA and RSA evaluations are underway.
