How long does a knee dislocation take to heal?

Hello doctor,

My right knee was injured while playing basketball a year ago. The knee was dislocated to the side but realigned automatically. It was swollen for over a week. A year later, I can walk, bend my knee, and perform jumps and squats without pain when the knee is straight. However, when I fully bend my knee, I experience pain on the back side of the right knee. Additionally, sudden twists during physical activities cause pain. I have been doing light exercises, but there has been no improvement. Despite the persistent pain, I prefer to avoid surgery if possible.

Please advise me on what steps I should take.
