AI Article Synopsis
- The study compares two surgical methods for repairing the anterior talofibular ligament (ATFL) in lateral ankle sprains: suture tape augmentation (STA) and suture anchor repair (SAR).
- Researchers tested 18 cadaver ankles to evaluate the effectiveness of these methods through biomechanical testing, focusing on load to failure and stiffness.
- Results showed that STA provided significantly better performance in terms of load to failure and stiffness compared to both SAR and the intact ATFL, while SAR demonstrated reliable biomechanical properties close to that of the intact ligament.
Article Abstract
Objectives: Currently, there are various surgical options for the treatment of lateral ankle sprains, and deciding which surgical option to use is a question worth considering. Furthermore, there is a relative scarcity of mechanical research comparing suture anchor repair (SAR) and suture tape augmentation (STA) internal brace for the repair of the anterior talofibular ligament (ATFL). Therefore, this study aimed to compare the efficacy of arthroscopically all-inside ATFL SAR and STA for reconstruction to treat lateral ankle sprains through biomechanical testing.
Methods: Eighteen fresh-frozen cadaver ankles were used for the study and divided into one of three groups: (1) intact ATFL group, (2) arthroscopically reconstructed with suture tape augmentation internal brace of the ATFL (STA group), and (3) arthroscopically repaired ATFL with suture anchors (SAR group). We used custom fixtures to test the specimens for loading to ultimate failure and stiffness.
Results: The mean load to failure of the STA group (311.20 ± 52.56 N) was significantly higher than that of the intact ATFL group (157.37 ± 63.87 N; p = 0.0016) and the SAR group (165.27 ± 66.81 N; p = 0.0025). The mean stiffness of the STA group (30.10 ± 5.10 N/mm) was significantly higher than that of the intact ATFL (14.17 ± 6.35 N/mm; p = 0.0012) and the SAR group (15.15 ± 6.89 N/mm; p = 0.0021). The suture anchor repair withstood failure loads and stiffness similar to the intact ATFL.
Conclusions: In terms of failure load and stiffness, the reconstructive outcome of ATFL reconstruction with STA is markedly superior to that of SAR reconstruction of the ATFL and the intact ATFL. Additionally, the novel technique of the SAR was a reliable technique that offered biomechanical properties similar to intact ATFL.

Background: There are few reports on the intra- and interobserver agreement and parameters for the diagnostic accuracy of ultrasound (US) imaging for chronic lateral ankle instability (LAI). The purpose of this study was to investigate the reliability and validity of US imaging for identifying anterior talofibular ligament (ATFL) remnants in patients with LAI.
Methods: A total of 547 ankles from 406 patients underwent surgery for LAI between 2019 and 2022.

Article Synopsis
- Injury to the deltoid ligament (DL) in conjunction with the lateral collateral ligament of the ankle can lead to complex rotational ankle instability (RAI), highlighting the need to understand how DL rupture affects ankle mechanics.
- A finite element model of the ankle joint was developed, using MRI data, to simulate various ligament injury scenarios and analyze the resulting biomechanical functions, focusing on stress distribution and joint dynamics.
- Results showed that combined ruptures of key ligaments significantly altered stress on cartilage and increased talus rotational angles during both internal and external rotations, suggesting that DL injury notably impacts ankle stability and function.

Objectives: An optimal load and ankle position for stress ultrasound of the injured anterior talofibular ligament (ATFL) are unknown. The objectives of this study were to compare stress ultrasound and ankle kinematics from a 6 degree-of-freedom (6-DOF) robotic testing system as a reference standard for the evaluation of injured ATFL and suggest cut-off values for ultrasound diagnosis.
Methods: Ten fresh-frozen human cadaveric ankles were used.

Article Synopsis
- Chronic ankle instability (CAI) arises from repeated ankle sprains, causing long-term sensorimotor dysfunction, with animal studies indicating that ligament injuries can lead to this condition.
- The study hypothesized that ankle instability from a sprain leads to degeneration of mechanoreceptors, which contributes to sensorimotor dysfunction and CAI development.
- In a laboratory study, Wistar rats with induced ankle instability showed decreased sensorimotor function and reduced mechanoreceptors in the anterior talofibular ligament over time, confirming the hypothesis.
