The unfitting things I see are that with the ankle they are going to implant using cadaver. With this, I have not and will never be able to run again according to the surgeon. It is a stage IV ocd of the talus. Bike testing would be out of the questions due to the BP meds I am on have calcium beta blockers keeping me from Ergo testing. Also, with the sleep apnea, I had a UPPP and tonsillectomy to try and help with the apnea but still CPAP is required even post surgery. I would love to stay my 20 but at this point, AF members must be fit for duty even worldwide qualified, even for a Personnelist like me. Even with the fitness program, this could place my AF AD career in jeopardy. At this point, my only hope is that if they do decide to cut me loose, it would be by med retirement but not until after my ankle surgery.
Before getting rated for anything, you need to be found unfit due to one or more conditions.
Sleep apnea is notoriously hard to get rated on, but I think it is possible depending on the facts. Use of CPAP, if unfitting, nets a rating of 50%.
For your ankle, here is the rating criteria:
5056 Ankle replacement (prosthesis).
Prosthetic replacement of ankle joint:
For 1 year following implantation of prosthesis 100
With chronic residuals consisting of severe painful motion
or weakness 40
With intermediate degrees of residual weakness, pain or
limitation of motion rate by analogy to 5270 or 5271.
Minimum rating 20
Note (1): The 100 pct rating for 1 year following implantation of prosthesis will commence after initial grant of the 1-month total rating assigned under § 4.30 following hospital discharge.
