Hi there ... I'm about 5 years late to this party!
@BionicButt, I haven't read your cerclage wire blog yet but will do so. I had a THR on my right side in Aug 2019. My femur suffered a slight fracture in the process and so the surgeon wired the bone. I had a difficult recovery, in part I'm sure because of the fracture (tho the surgeon said it shouldn't impact my recovery) and in part - I believe - because of the wire. For well over a year, I had bursitis - which I never had prior to the surgery, and a painful iliopsoas tendon (groin area) which prevented me from lifting my leg comfortably. Putting on socks, crossing my legs, getting in the car all required that I physically lift up my leg with my arms! I also could not do the one leg standing balance yoga pose, same as you! It felt like my leg would break and collapse if I tried to raise the other leg too much.
I saw PT's, acupunturists, I rested, I stretched, I tried everything. I went to HSS in NYC and the hip specialist suggested I have surgery to separate the iliopsoas tendon from the hip joint. Another surgeon also suggested the same. They said that while they couldn't see it in imaging, perhaps the tendon was being irritated by the new cup. Big problem though: if I did the surgery, I would trade pain for weakness. Which I already had and did not want more! So I decided to try one thing I hadn't tried - water therapy. First I started swimming, then I started Aqua Fit classes. It took awhile, but the iliopsoas pain subsided significantly. In the water, I was able to work and build strength in weakened areas in a way that i was unable to do on land. Even though there was much improvement in the iliopsoas, I still - 5 yrs later - am having issues that make it difficult to turn in bed, get up off the floor, lift and raise my leg sideways (such as standing sideways by a picnic table and trying to left the leg over the bench to sit). I also still feel discomfort in the actual joint sometimes when I walk and cannot do that standing leg pose.
So in my mind, I have to at least consider that it's the wire causing the problems. My left hip is now ready for a replacement surgery, and my surgeon is going to remove the wire from my right replacement at the same time.
I am hoping and praying that I have the same outcome that you described. I literally started crying when I read how much you improved afterwards!! It would be a dream for me to be rid of this discomfort and the limitations it is imposing on me. I'm hoping to have the surgery this April. Thank you so much for sharing your experience. It has given me great hope!!
