The lateral side of the ankle has three supporting ligaments: the anterior talofibular ligament (ATFL), the posterior talofibular ligament (PTFL) and the calcaneofibular ligament(CFL). The three ligaments are together called the Lateral Collateral Ligament Complex.

The function of the ATFL is to resist inversion and plantar flexion of the ankle joint. Injury to the ATFL usually occurs when the athlete's center of gravity is shifted over the lateral border of the weight-bearing leg, causing the ankle to roll inward at a high velocity.

1) The anterior talofibular ligament (ATFL), which connects the talus (ankle bone) to the fibula (outer leg bone) on the outside of the ankle. 2) The calcaneal fibular ligament (CFL), which connects the fibula (outer leg bone) to the calcaneus (heel bone)

Feb 28, 2025 · Ankle sprains involve an injury to the ATFL and CFL and are the most common reason for missed athletic participation. Treatment usually includes a period of immobilization followed by physical therapy. Only when nonoperative treatment fails is …

The three ligaments that make up the lateral collateral complex are the anterior talofibular ligament (ATFL), the calcaneofibular ligament (CFL) and the posterior talofibular (PTFL), and they are typically injured in this order during an inversion sprain.

For the lateral ankle ligament complex, the most frequently damaged ligament is the Anterior Talofibular ligament (ATFL). The mechanism of sprain injury of the ATFL and Calcaneofibular Ligament (CFL) is when a plantarflexed foot is forcefully inverted.

May 23, 2023 · Ankle sprains most commonly involve injury to the anterior talofibular ligament (ATFL) and/or the calcaneofibular ligament (CFL). Ankle sprains vary depending on the mechanism of injury (high- versus low-energy injuries), position of the foot, and rotational force on the joint and stabilizing ligamentous structures.

May 23, 2023 · The PTFL originates on the posterior border of the fibula and inserts on the posterolateral tubercle of the talus and runs perpendicular to the longitudinal axis of the tibia. Of the three ligaments (ATFL, CFL, and PTFL) only the CFL ligament is …

The PTFL fibers are interconnected with ligaments such as the ATFL and CFL. In our study, we found that the inferior fascia of the ATFL is connected to the PTFL in 10 cases (66.67%). Furthermore, the PTFL ligament was linked to the CFL ligament in nine (60%) ankles.

The main ligaments of concern are the anterior talofibular ligament (ATFL), the calcaneofibular ligament (CFL), and the anterior tibiofibular ligament (also called the anterior inferior tibiofibular ligament or AITFL). The AITFL is the anterior component of the syndesmosis complex (Figure 2).
