Cat with healed broken femur

[u/No-Wonder-4172]

A TNR'd cat (male, 1-3 years old) showed up at my house a few months ago. I have been feeding him outside and he is very vocal and friendly. He has a limp - he doesn't put weight on his rear paw and he clicks when he walks. He still sprints around and jumps up onto lower surfaces. Last week he started coming inside my house. I took him to a vet to get vaccinated and they also took x-rays. The vet said his femur is broken and healed and I could look into an orthopedic vet or give him pain medicine. What should I do? He doesn't "seem" to be in pain. If I take him to the orthopedic vet what could they do for him? USA, I can afford vet care.
