Autograft versus allograft tenodesis for chronic ankle instability: a single-center retrospective comparative study

J Comp Eff Res. 2021 Jan;10(1):5-11. doi: 10.2217/cer-2020-0070. Epub 2020 Dec 23.


Aim: To compare the outcomes of patients who underwent autograft tenodesis with those who underwent allograft tenodesis for the treatment of chronic mechanical ankle instability. Patients & methods: Ten patients who underwent allograft lateral tenodesis were compared with 15 patients who underwent lateral tenodesis using a split peroneus brevis tendon. Patients were followed up after an average time of 10.5 years. Results: No statistically significant differences concerning American Orthopaedic Foot and Ankle Society and Karlsson-Peterson scores were reported (p = n.s.). A reduced average radiographic anterior talar translation was observed in the autograft group compared with the allograft group (1.4 and 4.0 mm respectively, p < 0.001). Conclusion: Both surgical techniques significantly improved subjective and objective outcomes in patients suffering from chronic ankle instability compared with pre-operatory status. Autograft stabilization provided reduced post-operative anterior talar translation compared with allograft tenodesis.
