Preoperative and postoperative function and pain were graded using the Foot and Ankle Ability Measure (FAAM) and a visual analog scale (VAS), respectively. Postoperative imaging was assessed for osteochondral healing and degenerative changes. This included computed tomography (CT) at 6 months from surgery. Data regarding postoperative complications were recorded. All 30 patients that received allograft cartilage ECM for their OLT were evaluated for final follow-up at a mean of 20.2 months.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>Mean FAAM increased from 51.4 preoperatively to 89.3 of 100 at final follow-up. Mean VAS decreased from 8.1 preoperatively to 1.7 of 10 at final follow-up. These differences between preoperative and postoperative function and pain were statistically significant ( P &lt; .05). At 6 months from surgery, 2 patients (6.7%) received CT scans that revealed incomplete chondral formation at their OLT. At 19 months after surgery, a separate patient (3.3%) developed ankle arthritic changes.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion:<\/jats:title>\n                    <jats:p>Treating OLTs with allograft cartilage ECM has not been previously reported.
