Leg alignment correction Osteotomy
Conditions
Interventions
In the intervention group a patient-specific cutting guide will be used to
assist positioning and angle of the saw cut, and provide guidance on the degree
of angular correction from the pre-operativ

Design outcomes
Primary
| Measure | Time frame |
|---|---|
| The primary endpoint is the number of outliers defined as > 3 degrees difference between planned and achieved correction angle in frontal plane from 3D CT model. | — |
Secondary
| Measure | Time frame |
|---|---|
| The secondary endpoints will be the difference between planned correction angle (frontal and sagittal) calculated from X-rays and from 3D CT modeling. And the sum of costs of 1 CT-scan, 3D planning and printing, additional surgical costs (sterilization unit) and operative times as recorded in the electronic patient record for using patient-specific cutting guides. | — |
