| Year | Author | Patients | Duration | Gait parameter |
|
| 2013 | Lind et al. [68] | 11 male patients with medial OA | Before 12 months and after medial OWHTO | (1) Mean maximum varus angle during stance was reduced from 13.5° to 5.4°(normal 6.8°)
(2) Walking speed increased significantly postoperatively.
(3) Maximum knee flexion increased significantly
(4) Stride length increased from 1.37 m preoperatively to 1.48 m postoperatively
(5) The mean radiological mechanical alignment was changed (pre-op: 172°, post-op: 180°) |
|
| 2015 | Leitch et al. [70] | 14 patients with varus alignment and OA | Before 6 and 12 months after OWHTO | (1) Speed increased after surgery.
(2) The peak external rotation angle was increased after surgery |
|
| 2015 | Marriott et al. [71] | 33 patients with varus | Before 2 and 5 years after ACL reconstruction and HTO | (1) The means of valgus, flexion, and internal rotation angle increased by 7.79°, 3.80°, and 7.07°, respectively, with 5 years
(2) The means of extension and external rotation angle decreased by 2.14° and 5.88°, respectively, with 5 years |
|
| 2017 | Da Silva et al. [72] | 21 patients with OWHTO compared to the control group (16) | Short-term results of HTO of 6 months | (1) No significant changes in stride length and speed were observed in the post-op period
(2) The foot external rotation angle decreased significantly in the axial plane (25.5°–11.5°)
(3) Knee varus angle significantly reduced in the coronal plane (pre-op: 11.6°; post-op: 4.3°) |
|
| 2017 | Morin et al. [10] | 21 HTO patients | Preoperatively and at 1 year postoperatively | (1) The preoperative median of 7° varus (1–11°) was corrected to 3° valgus (0–6°)
(2) Time-distance gait parameters, such as step width and walking speed, did not change 1 year after surgery
(3) The patients’ subjective perception of their walking ability improved |
