Abstract
The aseptic loosening of the acetabular cup is a frequently complication in THA.
The most important problem in the revision surgery is the bone loss that complicates the surgical procedures and thus the success of the implant in the long term.
The homologous and heterologous bone grafts often represent the most widely used solution either in the morselized form, as a filler, or as structural graft with mechanical function.
These tissues, however, have biological limitations and lose most of osteogenic and osteoinductive capacity;all this leads to the use of growth factors such autologous platelet rich plasma(P.R.P.). At the Institute of Orthopaedic and Traumatology Clinic of Catania between September 2004 and December 2012 were undergoing surgery for acetabular hip revision 26 patients; in 18 cases the PRP has been associated with homologous bone, while in 6 cases with equine bone.
At a mean follow-up of 5 years(range 9–4 ys) the clinical and radiographic results were good in 23 cases, while, in 3 cases there has been an unsatisfactory result. We have not proved significant differences between the two groups of patients treated with homologous or equine bone.
To further assess the real effectiveness will have to be carried out randomized studies on a large scale and precisely determine protocols for application and provide clear guidelines.
