I am sorry to hear that you have had so many problems following this sports injury
. Fortunately it sounds like you have been able to preserve function for the most part.
It will be important to have continued followup of this injury with your orthopedic doctor
as well as physical therapy. This is because the most common complication of these types of injuries and repairs is stiffness and loss of mobility in the joint (in this case the ankle). Having continued physical therapy can optimize your changes to keep your mobility up. Also, if you develop significant recurring scarring you may need a repeat surgical procedure, which your orthopedic doctor would be able to decide.
In terms of other long term complications over your life, the most likely thing is that you will develop arthritis
in this joint. In fact, pain with standing or pain when in the cold may be early signs of arthritis. Arthritis is common in joints that have been damaged, and there is not much you can do to fix it. However, you can prevent worsening deterioration by stay fit, keeping a healthy weight, and avoiding high impact exercise routines that cause more stress on the joint.
