I had some tendonitis in my glute muscles before my THR. I believe they stretched the tendons during the surgery too much and I have a full thickness tear in glute min and tendonitis in glute medius. I did not have a normal recovery and have had pain ever since. I've had a steroid injection in the trochanter area which has alleviated pain and L3-5 ablation in low back that gets rid of the pain going to the hip area. (I have low back issues) I also had 2 sets of PRP injections with growth factors into the pelvis and hip tendons a few months apart and it didn't help. Therapists say doing exercises heal tendons since they don't have a blood supply. I do clams with bands and other exercises to help heal tendons. Nothing helps me. My hip doc said the surgery to attach tendons doesn't work. They don't care, they did their surgery. I was told hip surgeries were easy.
