drew9017,
It sounds like you have developed traumatic arthritis after your significant ankle injury.
You will need to discuss your treatment options with your surgeon. It appears that you do perform a lot of hard manual labor (working 65 hours a week and doing a lot of climbing). As such, you are probably not a candidate for a total ankle replacement (TAR). Currently, TAR are only recommended for sedentary patients, as they are still not very durable.
Usually, for patients who do a lot of manual type of labor and are still young, yet have uncontrollable pain after significant joint injury, it is recommended that the patient have the ankle fused (called an arthrodesis). This will usually reduce the pain, but it also takes away all motion at the ankle joint.
Again, you need to discuss all of your options with your surgeon. Good luck.
