All participants will undergo all arthroscopic ATFL repair surgery.

The patients undergo surgery with spinal block, general anesthesia, or a combination of both. During the diagnostic arthroscopy, the anterior compartment is examined with a 4 mm 30-degree camera, and lateral ankle instability is diagnosed arthroscopically

Pedobarographic analysis involves the completion of the platform, pressure sensors, software, and computer installation for gait analysis.

In dynamic analysis, the patient takes a step on the platform at a regular walking speed, with arms relaxed at the sides of the body, following a natural gait. In static analysis, measurements are taken while the patient remains stationary on the platform with arms in a free position next to the body. Five measurements are separately recorded for both feet during the step, heel strike, and toe lift phases. These measurements capture the highest pressures on the back of the foot, the middle part of the foot, the inner, middle, lateral side of the front of the foot, and the toes.

The plantar pressure distribution obtained from the measurement is divided into desired areas (masks). The pressure, force, and pressure-time integral corresponding to each area are then used to determine how and for how long these areas are exposed to pressure.

The hindfoot score comprises nine questions that assess pain, function, and alignment. Within the survey, one question pertains to pain, seven questions address function, and one question relates to alignment. The pain section is appraised on a scale of 40 points, the function section on 50 points, and the alignment section on 10 points, summing up to a total of 100 points. A higher score indicates better functionality.
