In 2020 The Mayo ended up putting in a larger spacer which tighten up the joint. It mostly resolved my “mid flexion laxity” issue. Just recently (2023), I had a left hip replacement. My left side is in total alignment now, and I’m doing PT now to get back to my active lifestyle. My best advice is to “never give up” and seek out the most experienced Ortho surgeons in the country. IMO, they will see you if you are persistent.
