Abstrakt:	Background: This study aims to analyze the safety and clinical efficacy of using double posterolateral coaxial portals for endoscopic treatment of posterior ankle impingement syndrome (PAIS), a procedure that has gained popularity in recent times. Methods: Six fresh foot samples were randomly selected to measure the distances of two posterolateral portals to the sural nerve in different positions (plantar flexion 10°, dorsiflexion 30°, and plantar flexion 30°) for safety evaluation. A prospective analysis was conducted on the clinical efficacy of the operative approach for endoscopic management of posterior ankle impingement syndrome, including evaluation of effectiveness and complications. Results: In this study, the mean distances of the first and second portals to the sural nerve were measured in different ankle positions. The distances were found to be 2.26 ± 0.22 cm and 1.59 ± 0.12 cm in the plantar flexion 10° position, 2.21 ± 0.21 cm and 1.55 ± 0.12 cm in the dorsiflexion 30° position, and 2.46 ± 0.29 cm and 1.73 ± 0.19 cm in the plantar flexion 30° position, demonstrating a significant safety margin from the nerve. A total of 38 patients underwent endoscopic treatment for posterior ankle impingement syndrome using double posterolateral coaxial portals between January 2012 and December 2017. This surgical approach provided access to the subtalar joint and posterior ankle region. The patients were followed up for an average of 38.2 months (24-72 months), with a satisfaction rate of 94.7%. There were no reported complications, and significant improvements were observed in both visual analogue scale (VAS) and The American Orthopedic Foot and Ankle Society Score (AOFAS) scores postoperatively. The VAS score decreased from 5.68 to 0.51 (P < 0.001), while the AOFAS score increased from 71.68 to 92.34 (P < 0.001), resulting in an excellent/good rate of 97.3%. Conclusion: The use of double posterolateral coaxial portals in the treatment of posterior ankle impingement syndrome offers several advantages, including improved safety, reduced risk of nerve injury, enhanced visualization of the posterior ankle and subtalar joint, favorable clinical outcomes, and minimal complications. Competing Interests: All surgical procedures were carried out by Rui Li, Yuan-qiang Li,Cheng-song Yuan, Wan Chen and Fang-yuan Wei in this study. The Data measurement of cadaver specimens was performed by Kun-gao He and Xiao-li Gou participated in the patient selection, investigation on the outpatient clinic and radiographic assessments, literature search, and data monitoring.
