Procedure: ACL reconstruction using the Over-The-Top technique

The procedure involves ACL reconstruction using the Over-The-Top technique, with the graft positioned over the lateral femoral condyle to provide anteroposterior and rotational stability.

The graft is secured using either metal staples or suture anchors, according to the assigned fixation technique.

The KT-1000 is a clinical-instrumental test widely used for the standardized assessment of patients undergoing anterior cruciate ligament (ACL) reconstruction. It provides an objective measurement of anterior-posterior knee laxity and is extensively used in both clinical practice and scientific research.

The assessment is performed with the patient in a supine position, with the knee flexed to approximately 30° and supported on a dedicated device. The examiner applies a standardized anterior load to the tibia while stabilizing the femur, and the resulting anterior-posterior displacement is recorded by sensors positioned in contact with the patella and tibial tuberosity.

The measurement does not have a predefined minimum or maximum value. Lower values indicate less anterior laxity and therefore better knee stability, whereas higher values indicate greater anterior laxity and worse knee stability.

For quantitative assessment of the Pivot Shift test, the KiRA sensor is secured to the skin over the anterolateral proximal tibia, specifically at the level of Gerdy's tubercle, using a hypoallergenic strap and an appropriate support to optimize stability. The device, which incorporates a triaxial accelerometer and gyroscope, communicates wirelessly with a dedicated application installed on a tablet, providing real-time quantification of tibial displacement during the clinical maneuver.

KiRA measurements are expressed in millimeters (mm) and represent the magnitude of anterior tibial displacement. There is no predefined minimum or maximum value for this continuous measurement; lower values indicate less tibial displacement and therefore better rotational stability, whereas higher values indicate greater displacement and worse rotational stability.

This is a clinical assessment form completed by the physician following a thorough physical examination of the knee. It includes several clinical tests to assess joint deformities, objective instability, and meniscal injuries. The resulting score determines an objective functional grade, classified from A to D: \*\*A\*\*, normal; \*\*B\*\*, nearly normal; \*\*C\*\*, moderately abnormal; and \*\*D\*\*, severely abnormal.

This is a validated outcome measure that assesses knee function through 8 items designed to evaluate the knee's ability to meet the functional demands of daily activities. It is commonly used to assess surgical outcomes in patients undergoing treatment for knee ligament or meniscal injuries.

The final score is calculated by summing the scores obtained across the individual items, ranging from 0 to 100. Scores are classified as \*\*Excellent (95-100), Good (84-94), Fair (65-83), and Poor (\<64)\*\*.

This is a 10-point unidimensional numerical scale used to assess pain intensity. The patient selects the number that best represents their pain intensity at that specific moment, ranging from 0 (no pain) to 10 (worst possible pain)

This is a 12-item multiple-choice questionnaire that provides two main summary measures: the \*\*Physical Component Summary (PCS)\*\* and the \*\*Mental Component Summary (MCS)\*\*. Together, these scores provide a concise and reliable assessment of the patient's overall health status.

Scores are typically reported on a 0-100 scale, with higher scores indicating better health-related quality of life.

This is a validated, knee-specific outcome measure used to assess symptoms and function in patients with ligament injuries or degenerative knee conditions. It consists of five subscales: \*\*Pain, Other Symptoms, Activities of Daily Living (ADL), Sport and Recreation Function, and Knee-Related Quality of Life (QOL)\*\*, providing a comprehensive assessment of the impact of knee pathology and treatment on joint function and quality of life.

Each subscale is scored from 0 to 100, with higher scores indicating better knee function and fewer symptoms, while lower scores indicate worse outcomes.

The Tegner Activity Scale is a validated measure used to assess the patient's level of physical activity on a scale from \*\*0 to 10\*\*, where 0 represents disability and 10 represents participation in competitive sports at a national or international level, such as football.

It is widely used to assess activity levels in patients with knee disorders. Patients will also be asked how many years they have been physically active in sports and whether any reduction or cessation of sporting activity is related to their knee condition.

Plazo: At least 24 months

To assess the patient's level of satisfaction, patients will be asked the following question: "Are you satisfied with the surgical procedure?" The response will be dichotomous (yes/no)
