abstract = {Background: An anterior cruciate ligament (ACL) graft rupture or a primary ACL injury in the contralateral knee is one of the greatest concerns of patients following primary anterior cruciate ligament reconstruction (ACLR). Our study describes the epidemiology and presence of concomitant meniscal injuries of patients with a graft rupture following primary ACLR or a primary rupture of the contralateral ACL following primary ACLR of the ipsilateral knee.
Methods: We reviewed the medical records of 42 patients who underwent a second ACLR. ACLR was performed using the ipsilateral semitendinosus and gracilis autograft. Variables extracted included the presence of concomitant MM and LM injuries intra-operatively, the patients’ level of intensity of sport (light, moderate, strenuous), duration of rehabilitation and mechanism of injury (contact, non-contact).
Results: Twenty-four (57.1%) patients had graft rupture of a previously reconstructed ACL of which 20 (83.3%) were male and 18 (42.9%) patients had a primary ACL tear of the contralateral knee following ACLR of the ipsilateral knee of which 18 (100%) were male. Patient who sustained a graft rupture were younger (29.5 vs. 31.9 years), had a higher body mass index (BMI) (26.42 vs. 25.10 kg/m2) and had a longer time before re-injury (6.18 vs. 4.94 years). Concomitant meniscal injury rates were comparable in both groups and the medial meniscus was injured more often.
Conclusions: This study describes the demographics of 2nd ACL injuries in the Asian population. Additional studies that investigate the differences in knee anatomy of Asians and Caucasians and their impact on ACL injuries should be performed.},
