Yes having surgery is frightening…. Something I think we all dread! Yes you will know for certain when you have to have your surgery as you will have difficulty moving… but where it’s affecting your sleep you should seriously think about doing it sooner than later. I waited too long. My hip would keep “popping out of place” after a seated position and I could no longer lift my leg to work my car pedals properly …. Hence I was very reconditioned going into surgery which I believe affected my recovery post surgery. Also, I had a posterior lateral incision, several muscles/ tendons were cut… I’ve had a long and difficult recovery still( am in PT intermittentingly 3 years later for chronic tendonosis of bilateral hips/ hamstring issues- did have a 1/2 inch leg length discrepancy). I wholeheartedly recommend the anterior approach- A muscle sparing procedure. Obviously it’s a discussion to have with your surgeon. Best of luck to you!
