Preface, that I'm a PT who works in outpatient orthopedics. Think about the anterior hip replacement. Less in the way of precautions, easier recovery. Only use an ortho who has done a ton of them though, it seems to be a little more technical of a surgery. I haven't seen much success with PRP or stem cell yet, but haven't had to many of them as patients. If you have little to no cartilage, not much you can do but the THR.
