Comparison of Clinical and Radiological Outcomes between Calibratable Patient-Specific Instrumentation and Conventional Operation for Medial Open-Wedge High Tibial Osteotomy: A Randomized Controlled Trial

<div>Simulation of the surgical procedures. (a) Installation of the PSI before the osteotomy. (b) Biplanar osteotomy with the aid of the osteotomy guide. (c, d) Calibration after the osteotomy. (e, f) Installation of the plate fixator under the guidance of the positioning wedge block. (PSI: patient-specific instrumentation. PTSA: posterior tibial slope angle.).</div>
