Outcome measures included Visual Analog Scale (VAS) for pain, Tegner Activity Scale (TAS) and return to sport rates, Lysholm score, International Knee Documentation\u00a0Committee subjective knee form (IKDC) as well as Knee Injury and Osteoarthritis Outcome Score (KOOS). Additionally, a standardized clinical examination and an isometric strength evaluation of knee extension and flexion were performed. It was hypothesized that high return to sport rates and good functional outcome would be observed and that the majority of patients would not present with a severe (&gt;\u200920%) knee extension strength deficit when compared to the contralateral side.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      A total of 7 patients (mean age 37.0\u2009\u00b1\u2009SD 13.5\u00a0years; 6 male\/1 female) were available for final assessment at a median follow-up of 17.0 (25\u201375% IQR 16.0\u201377.0) months. Three injuries occurred during ball sports, two injuries occurred during winter sports, and one injury each occurred during a motorcycling and skateboarding accident. The average time between trauma and surgery was 4.7\u2009\u00b1\u20092.6\u00a0days. At follow-up, patients reported little pain (VAS: 0 [0\u20130.4]). Return to sport was possible for all patients 8.9\u2009\u00b1\u20094.0\u00a0months postoperatively at a high level (TAS: 7.0 [6.0\u20137.0]). Five patients (71.4%) returned to the preinjury level of play, and 2 (28.6%) did not return to the preinjury level of play. Patient-reported outcome measures were moderate to good (Lysholm score: 80.4\u2009\u00b1\u200914.5; IKDC: 84.2\u2009\u00b1\u200910.6; KOOS subscales: pain 95.6\u2009\u00b1\u20096.0, symptoms 81.1 [64.9\u201389.1], activities of daily living 98.5 [94.1\u2013100], sport and recreation function 82.9\u2009\u00b1\u200914.1 and knee-related quality of life 75.9\u2009\u00b1\u200916.3). All patients were very satisfied (57.1%) or satisfied (42.9%) with the postoperative result. No postoperative complications were reported. Strength measurements revealed a severe knee extension deficit in 3 patients\u00a0(42.9%), but no significant deficit of isometric knee extension or flexion strength in comparison with the contralateral side was observed overall\u00a0(\n                      <jats:italic>p<\/jats:italic>\n                      &gt; 0.05).\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>Suture tape augmentation in acute PTR repair leads to good functional outcome without major complications.
