Repairs were augmented with a PUUR matrix. Factors evaluated included date of full weightbearing, patient satisfaction, Visual Analog Scale (VAS) pain score, strength, and ankle motion. The Wilcoxon signed-rank test was used to compare baseline and final follow-up VAS scores.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>A total of 18 cases were included in the study. The mean patient age was 54.61 \u00b1 8.25 (40-75) years with a mean follow-up of 163.61 \u00b1 57.81 (92-314) days. Patient satisfaction was obtained on 15 of 18 patients, with 14 patients satisfied with their outcome. Mean VAS for pain significantly decreased from 6.19 \u00b1 1.97 (2.5-9) to 0.83 \u00b1 1.54 (0-5) postoperatively, which was statistically significant (P &lt; .01).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>Achilles tendon augmentation with the PUUR matrix is a viable option in the treatment of IAT.
