I am sorry you are still struggling, but really, a cane at 3 months is not so unusual when there are complications of THR. But the continuing pain sounds like it is a concern to you, as it would be for me.

I have had 5 (not a typo!) hip replacement surgeries, the first 2 at age 55 and the next 3 at age 62 - the first round were not followed by PT, and I never did get a proper gait or full strength. When the implants failed and had to be replaced, the new surgeon was appalled that I had not had PT in the past, and sent me to a very good rehab team.

I did land and water therapy (I too had problems with weight-bearing for some time) and gait training. I had limped for so many years before the surgery, and again after the first round, that I needed a lot of help. Altogether, I spent over 3 months in twice a week therapy, and continued on my own for another 6 months. Needless to say, my results in round two were far superior to the first time. Now, some 7 years later, most days I walk at a brisk pace for an hour a day, or dance for 2 hours pain-free and (until Covid-19) was able to keep up with my 2 young grandsons all day.

If you can find a safe way/place to do PT, I strongly recommend you press your surgeon to refer you for therapy once the femur is healed - my friend had a similar complication back in November, and had to wait 12 weeks to begin therapy. She is still having therapy twice weekly and progressing well. She too has arthritis, and found an upright walker (like this: https://www.healthproductsforyou.com/ar-up-walker-walking-aid-upright-walker.html) was the solution to getting about with less pain.

As @naturegirl5 says, you must be assertive on your own behalf, because you are the one who has to live with the results. Good luck
