I've had core decompression on my left knee for avn found on the MRI scan. I think i have stage 3 osteonecrosis. Im looking fir guidance on recovery. Its been a week since surgery now, no weightbearing for 6 weeks, its horrendously frustrating and i have no pain. I need to know about recovery, physio etc. it's in a brace, is this operation really that major, wheelchair for 6 weeks? When can I start physio? I just can't find anything or anyone who had this op to give me some help? Im a scuba diver and desperate to get back in the water asap. Hope you can please?
