Very far off with what's available today. Unlike hips, total knees do not easily dislocate (come out of joint). So there is less concern about that happening in the middle of a strenuous activity. However, it is known that total knees do NOT last forever. They are little machines that will take care of you longer , if you take care of them!
How do total knees gradually fail? Well, they are actually cemented into the bone. And just like cracks form in the sidewalk over years after extremes of weather, cracks can occur in cement inside your knee. This is more likely if you "beat your knee up" on a regular basis. This is why it is not recommended that one chooses running for daily exercise after a knee replacement. The constant repetitive "jarring" could lead to cement cracks and eventual loosening of the implant. Most suggested is letting patients to play tennis (doubles is safer), ski, play golf, bike ride, swim, and do similar sports. Bike riding, Yoga and swimming are the best exercises. The stresses of impact, grinding and torquing is a sure formula for early failure. Thus, as things stand (and for any forseeable future), knee replacement must coincide with retirement from the NFL
