Percutaneous scalpel tenotomy is frequently performed as part of congenital talipes equinovarus (CTEV) to correct the equinus deformity. The use of a scalpel is associated with complications such as neurovascular bundle damage and pseudoaneurysms. In the literature, a percutaneous large-bore needle has been found to be a safer alternative to a scalpel for performing tenotomies. The goal of this study was to conduct a systematic review and report a single-center case series on the use of percutaneous needle tenotomy in the treatment of CTEV. A Preferred Reporting Items of Systematic Review and Meta-analysis (PRISMA)-compliant literature search was conducted to identify studies describing the use of a percutaneous needle tenotomy in the treatment of idiopathic CTEV. A retrospective case series of patients with idiopathic CTEV treated with percutaneous needle tenotomy over a seven-year period from a single center were also conducted. The patients' demographics, the location of the clubfoot, and the Pirani score were all recorded. An analysis of descriptive statistics was carried out. Continuous data were expressed as mean and SD, whereas categorical variables were expressed as absolute numbers and percentages (%). The systematic review included eight papers with a total of 1026 feet and a mean age of 10.4 weeks (SD 5.9). There were 47 (0.04%) complications across all studies, with a pooled success rate of 95%. Eleven patients (16 feet) were included in the single-center case study. The patients' initial Pirani score was 4.8 (SD 1.5), with a final score of 0. (SD 0). Four complications occurred in the patient's cohort - one minor bleeding and three recurrences as a result of poor compliance with the post-tenotomy foot abduction brace. In conclusion, the percutaneous Achilles tenotomy of a CTEV foot with a large bore needle is a safe and effective alternative.
