The ankle joint is an important weight-bearing joint in the human body

and lateral ankle sprains account for more than 75% of ankle injuries. This study mainly analyzed the main causes of lateral ankle injury from the perspectives of anatomical structure and biomechanics and proposed corresponding rehabilitation methods accordingly. It was found that the anterior talofibular ligament and the heel-fibular ligament play the main stabilizing role in ankle plantarflexion

while the posterior talofibular ligament plays a secondary role; the talofibular glide is wide in front and narrow in the back

which will move forward and rotate internally during ankle plantarflexion; the instability of the lateral ankle is related to many factors

among which the limitation of ankle dorsiflexion

heel inversion

imbalance of inner and outer ankle muscle strength

and decreased neuromuscular control are all important factors affecting the stability of the ankle joint. Patients are recommended to use ankle balance and stability training

proprioceptive training and functional ankle rehabilitation using joint release techniques

kinesio tapes and myofascial trigger point acupuncture to enhance the overall strength and stability of the ankle joint.
