Vermeijden HD, Yang XA, van der List JP, et al. - This study was undertaken to investigate failure rates and patient-reported outcomes measures following arthroscopic primary anterior cruciate ligament (ACL) repair of proximal tears in different age groups. Researchers retrospectively examined the first 113 consecutive patients treated with a repair at a minimum of 2 years between 2008 and 2017. The ipsilateral reinjury or reoperation, and contralateral injury rates were the primary outcomes, and Lysholm, modified Cincinnati, Single Assessment Numeric Evaluation, International Knee Documentation Committee subjective, pain, and satisfaction scores were considered as secondary outcomes. In patients aged 21 or younger (37.0%), the failure rate of primary repair of proximal ACL tears is high and this should be taken into account when discussing repair in this patient group. The data exhibited that repair may be an excellent treatment with low failure (3.5%) and complication rates (1.2%) and good subjective scores in patients older than 21.
