Our knees play an important role in so many of our physical activities. The knees provide stable support for our bodies, and they also allow our legs to bend and straighten. Both flexibility and stability are needed to stand, walk, run, crouch, jump, and turn.
The knee is a complex joint and it’s susceptible to injury during many sporting activities. If any of the structures within the knee are injured, you can experience pain and swelling, and the knee may not be able to function properly.
