ABSTRACT
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.
