Joint innervation in joint injury.

When considering joint innervation, it is important to appreciate that the joint receptors and the muscle tendon units about the joint interact in a complimentary manner forming a single afferent system. This system remains complex, and its overall function is still relatively unclear. Although the role of joint afferents can not be explicitly described, it is important to appreciate that alterations in joint innervation caused by athletic trauma can occur and can markedly affect joint function.
