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.
