Context: The management of multiapical and multidirectional deformities of the proximal tibia is still a challenging task with acute correction. The Taylor spatial frame (TSF) enables gradual correction in all planes. Aims: The study investigated the accuracy of correction for multiplanar proximal tibial deformities which had performed with the preassembled TSF. The complications and functional outcome were investigated. Settings and Design: Retrospectively, we compared the parameters of proximal tibial angles before and after using the preassembled TSF frame technique for correction. We used the mechanical axis deviation (MAD), medial proximal tibial angle (MPTA), posterior proximal tibial angle (PPTA), and tibial rotation as reference parameters for accuracy judgment. The deformities were divided into three main planes, each plane subdivided by two directions of angulations. Subjects and Methods: The study included 15 patients (20 tibiae), who underwent a tibial osteotomy surgery after obtaining informed consent for deformity correction using the TSF (Smith and Nephew, Memphis, TN, USA) between June 2016 and May 2018. Results: The three-plane deformities experienced an accurate correction of MAD. MPTA and PPTA were accurately corrected in patients with coronal and sagittal plane deformities, respectively. Rotational deformities were corrected to a satisfactory degree of accuracy in all cases. TSF correction for multiplanar proximal tibial deformities achieved an excellent result regarding functional outcome. Conclusions: Gradual correction for multiplanar proximal tibial deformities with the TSF is accurate, simple and with few complications.
