As a member of the 70+ crowd, I have had lots of friends undergo knee/hip replacements. The hip surgeries seem to go the best. I think it is important to manage expectations. Most are glad they had the surgeries as they are in less pain, have more mobility, etc. But no one came close to returning to their baseline, pre-arthiritis.The recovery period can stretch out for 1+ year. And for whatever reason, many folks who have had once such surgery seem to soon need another-on the opposite hip/knee, etc. In other words, it can start to feel endless. I hate to be negative, I am sure there are many unqualified successes as my sample size is small.
