Brief summary

Background: The PediLoc® Locking Cannulated Blade Plate System, originally designed for proximal femoral osteotomies, has also been used for multidimensional deformity correction of the distal femur. This study describes the surgical technique and retrospectively analyses consolidation rates of distal femoral osteotomies using this system, comparing them to distal femoral osteotomies using the DePuy Synthes® 90°LCP Pediatric Condylar Plate. Materials and methods: A retrospective review was conducted for patients who underwent distal femoral osteotomy with the PediLoc® Blade Plate (Blade Plate) and the DePuy Synthes® 90°LCP Pediatric Condylar Plate (90°LCP-PCP) at the University Children's Hospital Zurich (2020-2024). Consolidation rates were assessed using Reborn-, Rust-, and modified Rust-scores at 6 weeks, 3 months, and 6 months postoperatively and compared using an unpaired t-test. Geometric planes of osteotomy were analysed, and a stepwise correction technique was described.
