Objectives: Describing the results ofthe trans-physeal surgical technique on anterior cruciate ligament (ACL) tear and the appearance of eventual complications and setting the index of associated lesions from the initial diagnosis to surgery diagnosis.Methods: Retrospective study of patients under 18 intervened due to ACL injury with trans-physeal surgical technique between June 2010 and June 2018. Results: 39 patients were included, The average age was 14.7 years (9-17). Mean follow-up was 42 months (6-104) and average time until surgery was 10,7 months (1-48). Spearman correlation test associated positively (0.106) the increase in time to surgery and the increase in the number of associated injuries. There was 1 case of physeal bridge (2.5%) with lower limbs lenght discrepancy.Conclusion:Trans-physeal technique obtained good functional results with a low rate of complications at the end of follow-up in our serie. The increase in time to surgery was positively associated with the increase in associated injuries in the injured knee.
