Leg Pain
Published in Benjamin Apichai, Chinese Medicine for Lower Body Pain, 2021
The ankle is supported by many ligaments; the lateral ligament complex is a key structure because most ankle sprains are located at the lateral side. The anterior talofibular ligament (ATFL) connects the talus with the fibula.The calcaneofibular ligament (CFL) connects the fibula with the calcaneus.24The posterior talofibular ligament (PTFL) originates from the malleolar fossa and inserts almost horizontally into the posterolateral talus.25

The peroneal tendons are identified and dissected off the peroneal tubercle avoiding their laceration (Figure 2.15c). The tendons are freed from the anterior calcaneum, using a periosteal elevator and retracted anterosuperiorly within the sheath. The calcaneofibular ligament is then identified and peeled off the calcaneum. Then anterior end of calcaneum is exposed by working anteriorly over the calcaneum and releasing the bifurcate ligament.
The Anatomy of Joints Related to Function

A number of morphological features are directed toward resisting posterior shear forces. One is the shape of the trochlear surface of the talus, which is wider anteriorly than it is behind (Fig. 9A). This helps to prevent the mortise riding forward upon the talus during the stance phase, and this mechanism clearly also depends upon the integrity of the inferior tibiofibular syndesmosis and the posterior fibers of the collateral ligaments (including the posteriorly directed calcaneofibular ligament). Additionally, the socket of the mortise is deepened posteriorly by the downward extension of the tibial shaft (the “posterior malleolus”) and the inferior transverse tibiofibular ligament (Fig. 23A).
Finite element analysis of shank and ankle with different boot collar heights in parachuting landing on inversion ground surface

Chenyu Luo, Tianyun Jiang, Shan Tian, Jie Yao, Yubo Fan
The peak stresses of tibia, fibula, as well as cartilage of ankle joint and subtalar joint were analyzed. The medium collar boots would induce lower peak stress at tibia than the other two cases, while the collar height would not obviously influence the peak stress of fibula. Besides, medium and high collar boots would protect cartilages better compared to low collar boots through reducing peak stress of both ankle joint cartilage and subtalar joint cartilage. Furthermore, the peak forces of lateral ankle ligaments were also analyzed. The lateral ankle ligaments included anterior talofibular ligament, calcaneofibular ligament and posterior talofibular ligament. When landing on inversion ground surface, the ankle performed inversion motion in this simulation, and lateral ankle ligaments would be under damage risk, especially anterior talofibular ligament (Yu et al. 2016). The lateral ankle ligaments were protected best with medium collar boots.
Factors influencing return to play following conservatively treated ankle sprain: a systematic review

Inclusion criteria were articles assessing factors that may influence RTP following conservatively treated acute ankle sprain; Any grade of ankle sprain; new and recurrent; athletes practicing any sport activity at any level; any age range; both male and female patients and full text articles published in English from inception until May 2018. Ankle sprain in this review is defined as a traumatic injury that occurred to one or more of lateral ankle ligaments: anterior talofibular ligament, posterior talofibular ligament and calcaneofibular ligament. All types of study designs were considered to be included in this review. Articles were excluded if they did not include time to return to play (TTRTP) as an outcome measure at follow-up assessment and if they included participants following ankle surgery. In this review TTRTP is defined as number of days from injury until an athlete is back to sport activity. Animal and cadaver studies were also excluded.
Lateral ankle anatomical variants predisposing to peroneal tendon impingement

SPR plays an important role in stabilizing the peroneal tendons in the RMG, as a fibrous covering band which extends from the lateral malleolus posteriorly and inferiorly to be inserted at the lateral aspect of the calcaneus. The fibers of the IPR are continuous in front with those of the cruciate crural ligament; behind they are attached to the lateral surface of the calcaneus; some of the fibers are fixed to the peroneal trochlea, forming a septum between the tendons of the Peroneus longus and brevis. Also, the calcaneofibular ligament provides additional stability to the peroneal tendons in the RMG. The OP is a small sesamoid bone located inside the PLT, close to the cuboid. It is seen in 5–26% of the population and is bilateral in 60% of them. Painful os peroneum syndrome (POPS) is a term coined by Sobel et al. which results from a spectrum of conditions, including OP fracture or a diastasis of multipartite OP. These aforementioned OP abnormalities could result in or facilitate PL tendon tear or tenosynovitis, and POPS is frequently missed as a causative factor (Fig. 1).6,7
