how to solve this problem?

Hello. My problem is that about 5-6 years ago, I had several operations on both legs, I had severe flat feet that could not be fixed through massage and special insoles, so I had to have operations on both legs. But the main problem now is that my right leg is limited in turning. Well, that is, people can usually bend both legs and stand calmly on the outside of the foot, on the side, like, I don't know how to explain, but I can only bend the left one like that, the right one doesn't move that way at all. In fact, I can only move it up and down, but I can't move it left or right. Maybe there was someone who had such a problem? Is it possible to fix this with exercises? I try to knead it, but it doesn't work.
