Hi There,
Although it sounds like you're doing pretty well from the break and time in plaster, it would be a good idea to have a session or 2 from a physio who can advise you on the best exercises for regaining your strength and balance in that leg. You need to lose the limp asap and start working on your balance as well as muscle strength in the calf, front of your ankle, peroneal muscles, and intrinsic foot muscles. A physio can assess you and provide you with some really boring but effective exercises to get you back to full fitness asap.
It's not rocket science but it works!
Cheers,
