Abstract
In cementless joint arthroplasty, the first goal is the stabilization of the prosthetic components, due to bone ingrowth. In the past, to achieve the best fixation, the orthopaedic surgeons used osteoconductive materials (HA, TriCa-Ph).
To accelerate the fixation process, we have developed an osteoinductive procedure with growth factors. A product born from cancellous bone (BMP’s), bone marrow (stem cells) and plateled-rich plasma (growth factors) is applicated to the tridimensional fixation surface (spongiosametall) of the prosthesis. Since June 2003, we have treated 15 arthroplasties with this procedure (11 THA, 4 TKA).
The average duration of clinical follow-up was 6 month (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 exams were good. DEXA and RSA evaluations are in course.
In our opinion, the OSTEOKIN system is one of the most valuable growth factors system, to use always in arthroplasty surgery.
