Once radiographic healing is attained and you are walking and have progressed with the physical therapy then I would porbably let you back (im a foot and ankle surgeon/podiatrist). The issue with bad bi malleolar (tib/fib) fracture doslocations like yours is that normal day to day jumping forces and landings are not going to be detremential once the bones have healed.. You are just as likely to repeat the injury with another bad landing. Waiting longer will make no difference in that regard. What I see as more the issue is how strong and stable your lateral ankle is as running out landings will expose you to possible sprains. Obviosuly everyone is different but if you healed as expected I would say returning in 12 weeks or so is reasonable. And yes, you will unfortuntely be dealing with post traumatic arthritis in the next 10-20 years so keep your weight down and stay as active as possible. I see so many people that stop moving once the ankle becomes sore and gain weight as the years progress, causing even more pain. Good luck healing up and getting back to jumping!!
