USE OF PERONEUS LONGUS AS A GRAFT FOR ANTERIOR CRUCIATE LIGAMENT RECONSTRUCTION: A META-ANALYSIS.

To evaluate the advantages and disadvantages of anterior cruciate ligament reconstruction using the long fibular graft, compared to the hamstrings. This is a systematic review with meta-analysis, analyzing articles published in English and Portuguese between 1980 and 2025, in the databases MEDLINE, PUBMED, COCHRANE, and SCIELO. The variables of interest were: IKDC, Lysholm, AOFAS, sample size, and participants' age. Cochrane's Q test and I2 statistics were used to assess heterogeneity. Significant heterogeneity was identified when p-values were below 0.10, and I2 values were above 25%. Twelve articles were included in the scope of this review. The studies involved 1,212 patients, of whom 72.23% were male, and 18.49% were female. The follow-up time of the patients ranged from six months to five years. No statistically significant differences were found in IKDC and Lysholm of the two samples. There was a small statistical difference in the AOFAS scale. We did not find studies in the literature with sufficient relevance to demonstrate the superiority of long fibular reconstruction as a graft. There are also not enough studies to determine morbidity at the donor site. The use of the long fibular as a graft is promising, but requires caution.
