Is the knee joint stronger than the elbow joint, and why?
That depends on the integrity of the joint. There are several muscles that play an important role in stabilsing the elbow and the knee (too many to list) Either could be stronGer than the other if the opposing joint is weak and exposed to more stress than the other. Eg If a tennis player has his elbow joint balanced and his knee isnt then his knee would be regarded as weaker and therefore more prone to injury. However if the reverse were true then you would regard the elbow as the weaker joint. The second way to look at it is that if you look at what olmpic lifters and some strongman, they can squat anywhere from 260kg and more. Some powerlifters however can squat over 450kg but they dont get as deep as an olympic lifter. Both exercises stress the knee though. If you look at exercises that work the elbow the bench press would be the exercise that stressess the elbow the most. An example is a powerlifter who can bench press over 400kg with a bench shirt. A shot putter could bench over 2
