Answer

Researchers postulate that core decompression improves circulation by decreasing intramedullary pressure and preventing further ischemia and progressive joint destruction. The best results vary from 34-95%, which is significantly better than results of conservative treatment. [30] The best results are obtained when treating patients with early AVN (precollapse). Core decompression is also effective for pain control.
