Clinical Outcomes and Accuracy of Patient-Specific Instrumentation for Corrective High Tibial and Distal Femoral Osteotomy.

This study found that patients who underwent corrective HTO or DFO using 3D PSI had significant improvements in PROs; there was good accuracy of coronal correction with 88% of patients falling within 10% of the planned final mMTWr and moderate accuracy with 67% of patients falling within 3° of the planned final PTS. These findings demonstrate that osteotomy utilizing 3D PSI can lead to clinically meaningful improvements in patient function with high accuracy of planned correction.
