Closed-wedge tibial osteotomy: Conventional technique versus a new system of compression-dynamic fixation

Two groups of patients treated with different techniques of closed wedge tibal osteotomy were analyzed. Twenty-eight patients underwent the conventional technique and 31 patients underwent a closed-wedge osteotomy using a new osteotomy cutting jig and compression-dynamic fixation. The groups were comparable with respect to age, gender, and deformity. Using the conventional technique, only 68% of knees had an optimal postoperative femororbital angle between 167degrees and 175degrees, compared to 88% using the new device (P = .02). High tibial osteotomy with an osteotomy jig provides a more accurate correction of deformity than the conventional technique.
