Purpose: Core decompression is a surgical option since the 1960s for hip osteonecrosis treatment. This technique promotes bone repair by reducing intramedullary pressure, but this is not often enough to stop the progression of necrosis. The aim of this study was to associate core decompression with the regenerative stimulus provided by platelet-rich plasma (PRP) and compare our results with other regenerative techniques. Methods: Femoral head osteonecrosis was prospectively evaluated in 30 hips (22 patients, 15–60 years) treated by core decompression and PRP graft. Patients presented monolateral or bilateral osteonecrosis in stage I–IIA–IIB according to Arlet and Ficat classification. The outcome was assessed by changes in Harris Hip Score (HHS) and the need for total hip replacement (THA). Results: The mean preoperative HHS was 64 points, at two years from surgery was roughly 84 points. Sixteen of 30 hips showed osteonecrosis progression of the femoral head and were converted to THA. At the five year follow-up, the survival rate was 100% for patients at stage I, 67% for stage IIA, and 0% for stage IIB and was 68% and 32% for idiopathic and secondary osteonecrosis, respectively. Conclusion: Core decompression combined with PRP could be indicated as a treatment for the I and IIA stages of osteonecrosis, as it significantly reduces joint pain and delays THA. This procedure should be avoided in AVNFH related to cortisone therapy because only a few benefits have been proven. It also has the advantage of being technically simple, minimally invasive, and free from complications.

Abstract

Purpose: Core decompression is a surgical option since the 1960s for hip osteonecrosis treatment. This technique promotes bone repair by reducing intramedullary pressure, but this is not often enough to stop the progression of necrosis. The aim of this study was to associate core decompression with the regenerative stimulus provided by platelet-rich plasma (PRP) and compare our results with other regenerative techniques. Methods: Femoral head osteonecrosis was prospectively evaluated in 30 hips (22 patients, 15–60 years) treated by core decompression and PRP graft. Patients presented monolateral or bilateral osteonecrosis in stage I–IIA–IIB according to Arlet and Ficat classification. The outcome was assessed by changes in Harris Hip Score (HHS) and the need for total hip replacement (THA). Results: The mean preoperative HHS was 64 points, at two years from surgery was roughly 84 points. Sixteen of 30 hips showed osteonecrosis progression of the femoral head and were converted to THA. At the five year follow-up, the survival rate was 100% for patients at stage I, 67% for stage IIA, and 0% for stage IIB and was 68% and 32% for idiopathic and secondary osteonecrosis, respectively. Conclusion: Core decompression combined with PRP could be indicated as a treatment for the I and IIA stages of osteonecrosis, as it significantly reduces joint pain and delays THA. This procedure should be avoided in AVNFH related to cortisone therapy because only a few benefits have been proven. It also has the advantage of being technically simple, minimally invasive, and free from complications.
