Current double\u2010bundle anatomical reconstructions of the medial collateral ligament (MCL) increase the level of technical complexity, often resulting in the establishment of numerous bone tunnels and different fixation points with additional hardware. To overcome these limitations, we proposed a novel minimally invasive nonanatomical MCL reconstruction with one tibial tunnel in the metaphysis using Achilles allograft in the MLKI setting.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>In a retrospective study, we enroled 24 patients with MLKIs who underwent a new single\u2010strand short isometric construct (SIC) nonanatomical MCL reconstruction during 2020 and 2021. We fixed an Achilles allograft in one tunnel in the distal femur on the medial epicondyle and one tunnel in the metaphyseal part of the tibia using interference screws at 2\u2009cm below the joint line between the anatomical insertion of the superficial MCL and the posterior oblique ligament. The patients underwent clinical and radiological assessment at the last follow\u2010up, 1\u20132 years after the operation, including valgus stress radiographs, range of motion (ROM), Lysholm and International Knee Documentation Committee (IKDC) scores.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>The mean postoperative IKDC score was 77.8 (range, 50.1\u201386.6). The mean Lysholm score was 84.1\u2009\u00b1\u200911.9 (range, 96\u201359). The medial knee widening difference (i.e., mean side\u2010to\u2010side difference under valgus stress x\u2010ray) was measured to be 1.2\u2009mm on average. Only two patients (8%) had ROM limitation of 20\u00b0 in knee flexion, one of which had surgery failure. Results showed a significant statistical difference between the patients' outcomes according to the number of involved ligaments.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>This novel SIC\u2010like technique with a single tibial metaphyseal tunnel demonstrated satisfactory patient\u2010reported outcome measures, valgus stress radiographs, ROM and a low rate of knee stiffness and graft failure. While the number of injured ligaments in MLKI patients significantly influenced the outcomes, the results remained acceptable across all patients.<\/jats:p><\/jats:sec><jats:sec><jats:title>Level of
