In this retrospective study authors present the cases treated with allograft transplantation for ligament reconstruction in chronic ankle instability.


From January 1999 to December 2016, 72 patients were operated , including 29 women and 43 men, aged between 22 and 47 (average 29.5). Of the 72 patients treated, 61 were evaluated in the follow up (12 months-12 years, with an average of 59 months) with clinical and radiographic evaluation, AFASS score (American Foot and Ankle Society Scoring System) and grading according to Good et al.


There were no cases of transplant infection or rejection. Based on the criteria of Good et al., the results were excellent or good in the 57 patients operated with semitendinosus or frozen fresh gracil, sufficient in the 3 transplant cases of freeze-dried semitendinosus and 1 case of bad result.


Transplantation with allograft in chronic ankle instability represents an "innovative" technique that has achieved good results even in young patients with sporting needs.
