Hi there, how are you?
I would like to say I am sorry to hear you were misdiagnosed on your hip surgery, but I must say you look beautiful for your age; you would never know you were 50, so WELL DONE on taking good care of yourself

.
I spoke to someone some years ago, who was actually the first person in Britain to have a partial hip replacement, which was required after an accident on holiday about 3 years earlier.
His very lengthy scar wasn't nice to look at, but he was in out and done within 3 days and at the time, I saw him training again about 4 days after getting out of hospital and he was doing things like leg extensions, which don't target the hip flexors, but could have still been a slight risk of possible stitch rupturing and he didn't seem to intimate any stipulations about what he should and shouldn't do, as far as I recall.
Regarding the prohibited movements / exercises you were advised against, what exact reasoning was used? Damage to the new hip and / or surrounding tissues and / or potential damage to stitching, or something else and were such advised prohibitions deemed temporary or permanent?
