I have now done about 185 resurfacings for AVN cases over a 5 year period with many patients crossing the 4 yrs mark. It is interesting to note there has not been a collapse or fracture neck of femur even in a single patient.
It is wrong to think that the AVN continues forever in the femoral head. AVN is a one time event in which a strikingly similar sector of necrosis occurs in most femoral heads ( anteo supero lateral part) due to blockage of presumably the same vessel in all patients. This sets off a series of changes which are is marked by sectoral collapse. This is primary collapse of AVN and most patients are likely to develop it. Any kind of core decompression / bone grafting is a surgical attempt at preventing /postponing this event. These joint salvage procedures ( according to literature) achieves their
