BACKGROUND: Forces acting on the knee are different in contact and non-contact mode of injuries causing anterior cruciate ligament (ACL) tear. Purpose of this study was to determine the effect of mode of injury on the occurrence of meniscal tear and chondral damage in ACL tear. METHOD: 72 athletes with acute ACL injury (<3 months) were enrolled in the study. Depending on the mode of injury, athletes were divided into two groups - group A (non-contact mode of injury) and group B (contact mode of injury). 49/72 athletes had the non-contact mode of injury (group A), and 23/72 athletes had contact mode of injury (group B). Meniscal tear and chondral damage seen at the time of ACL reconstruction surgery was noted. All athletes were assessed at 12 months follow-up for return to sports, Lysholm score, and WOMAC score. RESULTS: In group A, 35/49 (71%) athletes and in group B, 9/23(39%) athletes had meniscal tear (p = 0.009). Medial meniscus was more commonly injured in group A [24/49] as compared to group B (5/23; p = 0.03). Chondral damage was also more commonly seen in group A [26/49] as compared to group B (5/23; p = 0.01). At one-year follow-up, 65% of the athletes from group B returned to sports as compared to 57% of the athletes from group A (p-value = 0.6). WOMAC score in group A and B was 95.5 ± 4.88 and 96 ± 4.39 respectively (p = 0.67). Lysholm score in group A and B was 1.02 ± 1.7 and 0.96 ± 1.2 respectively (p = 0.88). CONCLUSION: Non-contact mode of injury was associated with a higher incidence of meniscal tear and chondral damage. However, the mode of injury does not affect the functional outcome of ACL reconstruction surgery.
