This study reports a technical approach used in the application of computer-assisted navigation for patients undergoing a medial opening wedge proximal tibial osteotomy. Alignment of the limb can be monitored and documented at the beginning, during, and end of surgery. Surgical incisions are 4-6 cm in length and operative time (including the intra-articular arthroscopic procedure and osteotomy) averages 68 minutes, with 12 seconds of total fluoroscopy using a mini C-arm. Follow-up radiographic assessment in the office setting confirms corrections within 2° of the planned correction. Computer-assisted navigation is a valuable adjunct during opening wedge proximal tibial osteotomy as it provides real-time intraoperative information that contributes to and confirms decision-making.
