A close friend of mine of almost 40 years (60 year old retired fireman) from my gym was in terrible excruciating hip pain for many years and walked with a terrible limp. He had both hips replaced at the same time last year the week before Christmas. He was back in the gym with a cane the week after New Years pain free and working out lightly. We were all amazed. A week later - he came with a cane but didn't use it much. By the end of January, no cane but with a slight limp and worked out normally. By the end of February, couldn't detect any limp. Today, he does squats with 225lb for 12-15 reps, and rides the bike for hours. It was a miracle! He opted for the surgical technique that didn't involve cutting through the muscle so his recovery was very quick.
No one should fear hip surgery - it's the easiest surgical procedure to recover from - so I was told by a retired orthopedic surgeon friend whom I work out with.
