Demographics, imaging, treatment, and clinical follow-up data were retrospectively collected. Patients ultimately managed without surgery were rare and excluded. Patients with &gt;1 year of clinical follow-up or those who responded to prospective patient outreach for PRO collection were investigated for clinical outcomes, utilizing the Achilles Tendon Total Rupture Score (ATRS), Foot and Ankle Outcome Score (FAOS), Tegner Activity Scale (TAS), and questions about reinjury and RTS.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>\n                      Of the 38 patients identified, 24 (63%; mean age, 18.9 years; range, 10.4-22.8 years; 42% male) were analyzed for clinical outcomes. A total of 22 patients (92%) had complete tears, 2 had partial tears. Twenty patients (83%) returned questionnaires at a median 6.3 years (IQR, 3.4-9.7 years) while the other 4 patients were seen in clinic at a median of 1.2 years (IQR, 1.0-1.8 years) following injury. The median postoperative ATRS score was 96 (IQR, 82-100) and median TAS score was 6 (IQR, 4-8). Median FAOS scores were excellent for symptoms (91), pain (100), activities of daily living (100), and sports (98) and good for quality of life (88). The 6-month RTS probability was 47% (95% CI, 19%-66%) and at 12 months was 95%. The median time to RTS for partial tears was 5.6 months versus 6.6 months for complete tears (\n                      <jats:italic toggle=\"yes\">P<\/jats:italic>\n                      = .05).
