I had a double hip replacement about 8 years ago. After completing my Physical Therapy, I was told to avoid undue stress for 6 mos. What does you Doc say? As far as BHB, have a buddy drag your gear into shallow water and don it there. Less stress than walking. I am well past the initial recovery, and I still have some pain in my hips, particularly the left one. I don't let it stop me from diving. Boat dives are easy. I have some difficulty with rough shore entries on Bonaire, but just get my buddy to help me stay balanced.
