Table 3 Postoperative radiographic and computed tomography data. Presented as mean (confidence intervals) or number (%)

From: Should sagittal osteotomy line be parallel to tibial posterior slope in high tibial osteotomy?

Variable Mean (95% confidence intervals)
Change in TPS (°) 0.9 (0.4 to 1.3)
Coronal osteotomy plane angle (°) 16.6 (15.5 to 17.7)
Sagittal osteotomy plane angle (°) 6.2 (4.4 to 8.1)
Positive / negative value (knees) 64 (78%) / 18 (22%)
Coronal opening gap angle (°) 13.7 (13.0 to 14.5)
Sagittal opening gap angle (°) −0.7 (−1.4 to 0)
Positive / negative value (Knees) 40 (49%) / 42 (51%)
  1. Sagittal osteotomy plane angle with an anterior-widening proximal tibial fragment is showed as a positive value
  2. Sagittal opening gap angle with an anterior-opening gap is showed as a positive value
  3. TPS tibial posterior slope
