The present study involved patients diagnosed with MLKI at our institute from Spring 2006 to February 2021. A total of 71 MLKI cases were provided surgery due to knee instability and disability. For every patient, an arthroscopic diagnostic was performed to ensure that ACL tear and a remnant were present. When the ACL remnant was classified into group 2, 3, or 4 of Nakamae's classification, remnant-preserved single bundle ACL augmentation was performed. Graft selection and the combination of injured ligaments were evaluated. The side-to-side difference under an anterior tibial load of 134\u2009N with an arthrometer and the leg symmetry index at 60\u2009degrees\/s were measured. The present procedure was performed for five cases (male\/female: 4\/1, mean age: 33.6 years). The mean follow-up period was 26.4 months. The combination of torn ligaments was as follows: 3 cases of ACL\u2009+\u2009medial collateral ligament, one case of ACL\u2009+\u2009posterior cruciate ligament, and one case of ACL\u2009+\u2009posterolateral corner. An ACL augmentation graft was performed using an ipsilateral gracilis tendon in 2 cases, a contralateral full semitendinosus tendon in 2 cases, and the ipsilateral distal 1\/2 of the semitendinosus tendon in 1 case. The mean side-to-side difference was 1.07\u2009\u00b1\u20090.4\u2009mm. The mean leg symmetry index was 82.6\u2009\u00b1\u200912.2% in knee extension and 96.3\u2009\u00b1\u20099.9% in knee flexion. Although the present study was a small case series, the remnant-preserved single-bundle ACL augmentation for MLKI surgery provided good clinical outcome and conserved the graft resource. Even in the MLKI case, this technique is one of the useful surgical options. The level of evidence of this study is level IV (case series).<\/jats:p>","DOI":"10.1055\/s-0042-1749603","type":"journal-article","created":{"date-parts":[[2022,6,10]],"date-time":"2022-06-10T23:59:42Z","timestamp":1654905582000},"page":"1095-1101","source":"Crossref","is-referenced-by-count":4,"title":["Remnant-Preserved
