Two to five year results of primary ACL reconstruction using doubled tibialis anterior allograft

The aim of the study was to report the 2–5 year results of primary ACL reconstruction with doubled tibialis anterior allograft. Seventy-three patients who underwent primary ACL reconstruction with doubled tibialis anterior allografts with minimum 2 year follow-up were included in the study. Sixty-four patients were available for follow-up. The median age was 27 years (16–55). There were 33 men and 31 women. The median follow-up was 44.5 months (24–55 months). There were two complications, 1 DVT with subsequent PE, and 1 hardware problem. Four patients had failure of their graft, and six patients required repeat arthroscopy. The median Lysholm score was 88 (range 70–95), and the median Tegner activity score was 6.5 (range 3–10). The median IDKC was 92 (range 73–100). According to the IDKC score, 60% of patients were rated as excellent, 27% as good, and 13% as fair. A total of 25 were able to attend the clinical assessment. On KT-1000, 15 (60%) patients had less than 3 mm side-side difference. Eighteen patients (72%) had no pivot shift. ACL reconstruction with allograft tibialis anterior tendon provided good functional results with a low-failure rate at 2–5 years. There was a statistically significant difference in outcome between men and women, with men performing better on the Lysholm and the IDKC scales.
