I'm a 77 year old male with recent arthroscopic surgery on my left knee, a month ago. My right knee has a ruptured ACL which is inoperable since it does cause pain and knee stabiltiy is OK. That occurred in 1992. In early 2023 I slipped off the bottom rung of a step ladder and suffered 3 line fractures (inoperable) in my pelvis, a stress fracture in one or more lower vertebrae, and more damage to my back including 2 sets of vertebrae bone on bone, some scoliosis now, and 3 other sets of vertebrae with protruding discs in the range of 3 mm protrusion. I have a left hip replacement circa 2016 that is beginning to cause aches during walking, making me think it may need repair. The chief ortho surgeon at Hoag Orthopedic Institute says my right hip is bone on bone but will not replace it because I have no pain radiating from it, although they admit the joint is significantly deteriorating (osteoarthritis).
