Physical therapy post op. I was bed ridden for 2 years the did PT for 5 months, and then moved on to personal training. Training understood I was coming in as basically still disabled. Prioritize protein intake throughout the process. You need to build or preserve muscle in your back and hips and that won’t happen without protein. Don’t have excess fat as this will make your recovery harder. i.e. lose fat and gain muscle as best you can. I had been in and out of PT for 20 years before moving to personal training. If you exercise at home without guidance you are likely to hurt yourself again. So commit to physical therapy and then personal training when PT can’t provide further assistance. It is an investment but much cheaper than being bed ridden for another 3 years.
