Buddy,
I had my left hip resurfaced by Dr. Bose in Chennai in March of 2007. I was a serious athlete earlier in life, playing college basketball and a lot of tennis. I had not played any tennis 3 years prior to the surgery because I just could not move well and the pain was too great.
I am happy to say I am beating guys I was not beating several years prior to the surgery and, in fact, am beating guys I had never beaten previously. But I will say I was much more patient and careful during my recovery than some I have read here. I did not even try to play tennis or anything else that would impact the joint for the first year. I took it very slowly, pretty much only swimming.
At no point, though, did I have any pain that would have prevented me from attempting to play earlier. I just felt this is something that I want to last me for the rest of my life so I wanted to ease into it and make sure all the muscles were healed and the cup was fused and secure.
Knock on wood, couldn't be happier. No problem with lateral movement or any other type of movement.
Good luck, Bill
