Table 2 Comparison of relevant parameters before and after the modified CWHTO in patients with tibia vara

From: Osteotomy at the distal third of tibial tuberosity with LCP L-buttress plate for correction of tibia vara

Characteristic Before After p value
Femorotibial angle (range) 186.2° ± 5.1° (179° to 209°) 173.3° ± 2.0° (170° to 178°) <0.001
Paina 2.35 ± 1.6 0.56 ± 1.0 <0.001
Posterior tibial slope (range) 5.9° ± 2.4° (0° to 11°) 2.8° ± 1.9° (−3° to 7°) <0.001
Insall-Salvati index (range) 1.03 ± 0.13 (0.8 to 1.3) 1.02 ± 0.14 (0.8 to 1.3) 0.161
  1. Data are presented as means ± SD and were recorded at baseline (before) and at the last follow-up (after) for n = 75 operated knees in n = 46 patients. Patients were followed up after plate removal for 15–46 months. aPain was assessed by the VAS pain score.
