Background: the standard arthroscopic ACL (anterior cruciate ligament) reconstruction using different techniques and grafts has been linked with failure rates of nearly 16%. To decrease the need for revision ACL surgeries modified Lemaire's technique has been widely accepted which adds the procedure of tenodesis laterally and reduces the anterolateral laxity. Aim: The present study aimed to evaluate the functional outcome of lateral extraarticular tenodesis with anterior cruciate ligament reconstruction with a modified Lemaire procedure. Methods: The present study assessed 60 subjects who underwent modified Lemaire's procedure with ACL reconstruction at the Institute. The subjects were postoperatively followed at 6 months, 1 year, and 2 years. The parameters assessed were IKDC (International Knee Documentation Committee) scores, Tegner–Lysholm scoring, and pivot shift scores preoperatively and postoperatively. Results: The study results showed that all 60 subjects that underwent modified Lemaire's procedure showed improvement in IKDC scores and Tegner-Lysholm scores and a significant reduction in pivot shift scores was also seen. A statistically significant difference was seen in preop Lysholm scores and 6-month Lysholm scores and at 1 and 2 years Lysholm scores with a p-value of <0.05. Conclusions: The present study concludes that Lemaire's technique is a good technique that results in reduced rates of revision ACL surgeries with an improvement in postoperative IKDC scores and Tegner-Lysholm scores. Modified Lemaire's technique also assesses anterolateral deficiency with a reduction in the prevalence of pivot shift.
