Well, in realistic times, if the knee becomes worse, you won't be fully unable to work. Maybe only for short period of time, while your knee replacement heals though. As that is what would be next if it got worse. It wont disable you from working the rest of your life.

Bad Boy is correct, having a bad knee should not keep you from working.

I worked after my injury until I had the meniscus surgery 5 months later, then I returned to work with restrictions after the surgery.

With a knee replacement most people reach MMI at 1 year after surgery and are released to return to work with restrictions.

Bummer, that is very correct. If I only had an injury to my knee, and then had the Knee replacement done, I would have been able to return to my job, which was Classified Very heavy Work Duty functions. Even though there are restrictions, I would have been able to Compensate for them.
