Clinical Outcome of Medial Opening Wedge Osteotomy with T-Locking Plate : Two Years Follow-Up

OBJECTIVE This study was undertaken to determine clinical outcome after medial opening wedge osteotomy with Tlocking plate, with two- year follow up. Twenty-two patients (22 knees) who underwent medial opening wedge osteotomy with T-locking plate (stainless steel 316L, 6 holes) for treatment of varus malalignment of the leg between March 2005 and April 2008 were included in the study. The amount of correction ranged from 7° to 19° (mean, 9.77°). Clinical and radiographic findings were evaluated with VAS and the Lysholm score at sixth, twelfth and twenty- fourth months. Follow-up ranged from 18 to 37 months (mean, 2.1 years). Significant reduction was observed of VAS, from 4 (range: 3.5-5) to almost free of symptoms (1.0 to 0.5) at the twentyfourth month follow-up (P<0.01). Good results were achieved in the Lysholm score (P<0.01). Medial opening wedge osteotomy with T-locking plate is safe and efficient procedure for corrective varus deformity of knee.
