Cruciate ligament of the knee lies between tibia intercondylar eminence and femoral condyle nest, presents hinged appearance and has both the function of biomechanics and proprioception, which is processed using mechanoreceptors in the tibial and femoral ligament attachment point. Mechanoreceptors could be divided into 4 groups: Ruffini ending, Pacinian body, Golgi tendon ending, and free nerve ending. The amount of mechanoreceptors of the cruciate ligament after acute injury will change in line with the duration of injury: the longer the time lasts, the less the receptors will be. But some hold the opposite view and consider that the receptors do not have evident atrophy and decline. Due to inflammation in the progression of osteoarthritis, cruciate ligament will gradually degenerate, and knee proprioception will abate as well. However, whether the amount of mechanoreceptors are associated with osteoarthritis progression and severity of the situation is not clear. The number of the damaged cruciate ligamen
