When you extend, or straighten, your knee beyond a straight line, itâs called hyperextension, which can injure the knee and other parts of your body. Itâs quite common among yoga students at all levels, and certain asanas can exacerbate the condition if you repeatedly do them incorrectly.
There are also several large tendons that cross the back of the knee and normally help prevent hyperextension: the hamstring tendons coming down from the back of the thigh and the gastrocnemius tendons coming up from the calf.ut in many joints, ligaments and tendons play a major role in preventing excessive motion; if those tissues become too loose, the joint can move in ways that cause damage or set the stage for injury. A joint with such laxity is said to be hypermobile, and the knee is particularly vulnerable to this problem.
