This study evaluates the outcomes of combined Anterolateral Ligament (ALL) and Anterior Cruciate Ligament (ACL) reconstruction in patients with ACL deficiency. A total of 12 patients underwent arthroscopic surgery using the modified Lemaire technique for ALL reconstruction. Preoperative and postoperative assessments showed significant improvements in Lysholm scores, indicating enhanced knee function. The study also monitored pivot shift tests, which demonstrated effective stabilization post-surgery. Complications were minimal, suggesting the procedure's safety. The authors advocate for the combined approach to address knee instability effectively. The findings support the role of ALL reconstruction in conjunction with ACL surgery. The study contributes to the understanding of knee joint mechanics and rehabilitation. Future research is recommended to further explore long-term outcomes. Overall, the combined reconstruction shows promise for improving patient quality of life.
