%X OBJECTIVE: To comprehensively assess the clinical efficacy of the anterolateral thigh flap in lower limb reconstruction (LLR) surgeries and explore its application value via a meta-analysis.
METHODS: Published articles on the efficacy of anterolateral thigh flap in LLR were retrieved in English databases such as PubMed, Web of Science, Embase, and The Cochrane Library, which were searched from their inception to November 2023. The search terms included "anterolateral thigh flaps", "lower extremity", "free muscle" and "reconstruction". Subsequently, data extraction of eligible studies was carried out, and data analysis was conducted using RevMan 5.3 software.
RESULTS: The final selection comprised 12 appropriate studies, encompassing a total of 577 patients. Meta-analysis demonstrated that negligible differences existed in the length of hospital stay among patients treated with different types of flaps (mean difference (MD) =-0.10, 95% confidence interval (CI) =-0.400.20, P>0.05). Additionally, the occurrence of complications differed slightly (Risk difference (RD) =-0.02, 95% CI=-0.090.05, P>0.05). The incidence of secondary surgeries also demonstrated non-significant differences (RD=-0.04, 95% CI=-0.11-0.04, P>0.05). Nevertheless, patients who underwent anterolateral thigh flap transplantation exhibited a drastic decrease in donor site morbidity (Odds ratio (OR) =0.22, 95% CI=0.10-0.49, P<0.05).
CONCLUSIONS: The clinical efficacy of the anterolateral thigh flap in LLR surgeries shows no significant differences in hospital stay, complication rates, or the need for secondary surgeries compared to other flaps. However, using anterolateral thigh flap in LLR significantly reduces donor site morbidity.
