The human body has more than 20 different ligaments, according to the University of Arkansas for Medical Sciences. They are found in the back, upper limbs, lower limbs, chest, abdomen, pelvis, head and neck.
One of the most well-known ligaments is the anterior cruciate ligament. The ACL connects the thigh bone to the tibia, which is found in the calf. The American Academy of Orthopaedic Surgeons estimates that approximately 200,000 ACL injuries happen each year.
