Intervention model description: Participants will undergo, in a previously randomized manner, two surgical techniques for reconstruction of the anterior cruciate ligament of the knee. The two techniques differ in the preparation of the graft. Group 1: ACL reconstruction surgery with the conventional technique or, Group 2: Conventional reconstruction surgery of the Anterior Cruciate Ligament + Reconstruction of the Anterolateral Ligament of the knee. The literature indicates that both techniques have good results, but the differences during the rehabilitation process are still unknown. Both groups will be evaluated and reevaluated in the same way. Also, both groups will undergo the same rehabilitation protocol with manual therapy, physical resources (heat, cold, electrotherapy), kinesiotherapy, and isokinetic exercises.
Primary purpose: TREATMENT

Brief summary: The objetive is compare knee joint stability, functional capacity, postural control, activation, and muscle strength of patients undergoing conventional Anterior Cruciate Ligament Reconstruction or the conventional Anterior Cruciate Ligament Reconstruction + Anterolateral Ligament Reconstruction technique of the knee, and rehabilitation for up to nine months. This project aims to include patients with ACL injuries already treated at the Knee Outpatient Clinic of the Hospital das Clínicas da UEL (HC-UEL), coordinated by the orthopedic physician Dr. Lucas da Fonseca Borghi, who has his master's degree related to this research project. Twenty patients between 18 and 50 years old, of both sexes, sedentary and/or active and/or athletes, diagnosed with unilateral injury of the Anterior Cruciate Ligament will be included. These patients will be evaluated, submitted to ACL surgery (conservative) or associated with ALL reconstruction and undergo rehabilitation with physiotherapy in conjunction with the extension project Sports Physiotherapy from Theory to Practice - Phase III (PROEX-UEL No 02675), coordinated by Prof. Dr. Christiane S. Guerino Macedo - advisor of this research. Expected results: It is expected that the group undergoing ACL + ALL reconstruction will present better knee joint stability, functional capacity, postural control, activation and muscle strength.
