Hi Ross
I have had 7 hip replacements and 7 dislocations! I know wow
I had a anterior approach done on my left 10 years ago and had no problems with that and recovery was good . The other 6 were on the right and done posterior, although the first was ok I had a bad surgeon and she placed and used wrong sizing etc so when I had a fall off my horse 4/5 years into it it moved and I had lots of pain for a few years until I finally found out I had damaged it and they x rayed the wrong side ! Anyway I then had 2 have a revision 5 years ago which went well but unfortunately I got a infection that took 2 years to find . Always check your blood tests for any signs ( high crp , white blood cells. , and anaemic ) I then went through 2 2 phase surgeries to get rid of infection I kept dislocating and no one really knew why ? Lots of speculation but muscle and tendon damage from infection was a main cause , but sizing of ball and stem and placement is also important.
I am 3 weeks post my last operation in which I had a capsular liner put in to stop it coming out . So far so good
Do your homework and research your surgeon
All the best
