The aim of this study was to assess the safety and efficacy of percutaneous low-energy osteotomy and casting in treatment of pathological coronal knee deformities in children equal or younger than 6 years. A prospective nonrandomized case series study was conducted. A total of 62 (109 limbs) patients with pathological coronal knee deformities were treated by percutaneous low-energy osteotomy and casting and observed over 3–10 years. The pathological nature was variable (rickets, Blount disease, dysplasia, after trauma, or after infection). The average age at the time of surgery was 4.5 years (range: 3–6 years). Clinical and radiological outcomes were evaluated annually and at the end of follow-up period. There was a statistically significant improvement of the clinical appearance and the radiological parameters regarding mechanical axis deviation and tibiofemoral angle at the end of follow-up period. The total complication rate was 6.4%, with only four limbs with overcorrection and three limbs with recurrence. Percutaneous osteotomy is a simple, safe, and effective option in the treatment of children with coronal knee deformities equal or younger than 6 years.
