There is limited information in the literature regarding these rare presentations, with even less information regarding clinical outcomes. Using propensity\u2010score matching, the purpose of this study was to compare the outcomes of MLKIs with and without patellar tendon ruptures and to investigate the overall predictors of these outcomes.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>Twelve patients who underwent surgical repair for combined MLKI and patellar tendon rupture from 2011 to 2020 with minimum 1\u2010year follow\u2010up data were identified from two separate institutions. Patients were propensity\u2010score matched with a 1:1 ratio with controls based on age, body mass index (BMI), gender, and time from surgery.

The average follow\u2010up was 5.5\u2009\u00b1\u20092.6 years. There were no differences in Schenck Classification injury patterns. There were significant differences found across IKDC (Patellar Tendon mean: 53.1\u2009\u00b1\u200924.3, MLKI mean 79.3\u2009\u00b1\u200919.6, <jats:italic>P<\/jats:italic>\u2009&lt;\u20090.001) and Lysholm scores (Patellar Tendon mean: 63.6\u2009\u00b1\u200922.3, MLKI mean 86.3\u2009\u00b1\u200910.7, P\u2009&lt;\u20090.001) between the two, illustrating poorer outcomes for patients with concomitant patellar tendon ruptures.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>In the setting of MLKI, patients who have a concomitant patellar tendon rupture have worse functional outcomes compared to those without.
