Aggravating a Pre-Existing Condition in Arizona Work Comp

I had an interesting case today where the insurance carrier's doctor is saying that my client's need for a total knee replacement is not related to his 1985 industrial injury because he had a prior non-industrial injury in 1974.  His argument is that, since there were already degenerative changes in the knee at the time of the 1985 injury, he would have needed the total knee eventually regardless of whether he had the industrial injury. 

This is actually a very common issue in Arizona Workers (Workmans) Compensation claims - where a worker has a pre-existing non-industrial degenerative condition that is aggravated or exacerbated by an industrial injury.  It is generally accepted that, if the subsequent work injury causes a permanent aggravation of the underlying condition, or speeds up the need for care for the degenerative condition, it is the workers comp carrier's responsibility.  Although there is not a specific test for this, the industrial injury has to be at least a "substantial contributing factor" in adding to the need for the treatment - "substantial", however, is ill defined and can mean at least a minimal factor in causing the need for the treatment. 

Bottom line:  a pre-existing condition can either be temporarily aggravated or permanently aggravated by an on the job injury and be covered under workers compensation.  This usually has to be established by medical testimony from your doctor.

  1. I am almost done with my carpal tunnel compensability case. After 3 hearings the ICA judge is allowing me, per my request, to submit a closing statement memorandum by May 31.
    My witnesses have generally corroborated my evidence with testimony that I was not typing much at all outside of work, and that the onset of heavy work requirements paralleling the onset of my CTS.
    My physician (a board certified chiropractic rehab specialist) testified that causality by heavy repetitive typing due to work "was easy to see."
    The defense's hired IME, board-certified hand surgeon testified that to a reasonable medical probability my CTS was not related to work. He cited 5 studies in the past 10 years that say CTS is "related" to various risk factors, of which I have several (diabetes, female gender, 40+ age, 32 BMI, pre-existing CTS in 2005 from heavy typing at work but not claimed as a work comp injury at the time).
    Do I have a chance at winning my caae with so many risk factors although the ONLY time I experienced CTS symptoms was when typing for work (office or home)?
    URGENT!
