Genu recurvatum is a deformity in the knee joint, so that the knee bends backwards. In this deformity, excessive extension occurs in the tibiofemoral joint. Genu recurvatum is also called knee hyperextension and back knee. This deformity is more common in women [citation needed] and people with familial ligamentous laxity. [2]
Hypermobility, also known as double-jointedness, describes joints that stretch farther than normal. [2] For example, some hypermobile people can bend their thumbs backwards to their wrists and bend their knee joints backwards, put their leg behind the head or perform other contortionist "tricks".
Frontbending skills such as folding forward at the waist with the legs straight, or placing one or both legs behind the neck or shoulders with the knees bent (called a human knot). Backbending skills such as touching one's head to one's feet, or all the way to the buttocks (called a head-seat), while standing, lying on the floor, or in a handstand.

A patellar dislocation typically occurs when the knee is straight and the lower leg is bent outwards when twisting. [1] [2] Occasionally, it occurs when the knee is bent and the patella is struck directly. [1] Commonly associated sports include soccer, gymnastics, and ice hockey. [2] Dislocations nearly always occur away from the midline. [2]
