In reply to david morse: I broke my ankle in an ice climbing fall 16 years ago. The talus was punched up throught the joint, snapping the bottom off the tibia and crushing the joint surface. After a bone graft to rebuild the surface and pins and a plate inserted, the bone healed fine (but is much thicker than it used to be).
My problem is that the cartiledge was damaged so I now have arthritis and may well need fusion soon.
I have been able to climb since the accident although I didn't winter climbing for 2 years, however the joint carried on improving for about 3 years before stabilising for another 4 or 5 and then deteriorating since then.
The climbing itself isn't the problem, but walking in/out, especially long days in winter or the Alps, likewise it stiffens up terribly the next day.
I find trekking poles help, as does wearing approach shoes rather than boots (when possible) as well as taking lots of ibuprofen, but there are issues with stomach ulcers with their long term use.
I also had a steroid injection last year which made a huge improvement but it only lasted 2 months and as you can only have a limited number of them I can't have another.
If you have cartiledge/arthritis problems hyalgon injections (also called ostenil) may help. It contains a substance found naturally in the synovial fluid of cartiledges. You need 3 to 5 injections initially and then a top up every 6 months or so. I believe its only NICE accredited for knees but I know some consultants use it in ankles although you may have to go private and that would be about £150 to £200 per injection.
Unfortunately by the time I heard about hyalgon the consultant said it was too late for me as there wasn't enough cartiledge left to inject into. However you are younger and your injury is more recent so I'd check it out while time is on your side.
Personally I'm putting off fusion as long as possible as I'm concerned about the long term knock on effects on my knee, hip and back caused by walking with a limp, plus general hassle like not being able to use the accelerator properly while driving etc. Until they can regrow cartiledge tissue (stem cells perhaps?) all treatments are just buying time.
