hi your find its the reverse bone shaving is done to help get rid of differences in the joint to help it work smoother. perhaps you do need it redone to ease your pain along with some weight loss. good luck
could osteoarthritis localized to a hip be caused by having had bone shaved from that joint 16 years ago? . the shards of bone shaved from my right hip were used in conjunction with titanium for an l5-s1 spinal fusion. yes i am overweight and progressively so as my hip continues to cause excruciating pain especially when moving.
