Deformity correction
Rotational deformity (in-toeing & out-toeing) before & after — Dr. Donghoon (DALRI)
Once surgery and the full recovery period are complete, what changes is: CT torsion measurement first, so the correction angle is exact · Correctable together with angular deformity in one SADO operation
Before: what is recorded
Before surgery the team documents the starting point of everyone considering rotational deformity (in-toeing & out-toeing) — Visible in-toeing or out-toeing gait · Patients whose legs still look unnatural after angular correction — together with radiographs, alignment measurements and the patient's own goal, so there is a fixed baseline to compare against.
How the change is measured
Deformity is quantified in degrees on standing full-leg weight-bearing radiographs, comparing the mechanical axis before and after surgery along with knee or ankle gap and rotational profile. The goal is an axis that passes back through the centre of the knee.
Timeline from surgery to normal life
- 01Day of surgery: the bone is cut and realigned to the pre-planned angle, with the axis confirmed on intra-operative imaging.
- 02Similar to other realignment surgery, with no cast when internal fixation is used.
Limits and what cannot be guaranteed
- 01Bone lengthening is major surgery. Outcome and recovery time depend on bone quality, age, weight and how disciplined the patient is with rehabilitation, so identical results cannot be guaranteed.
- 02Results differ from person to person: bone-forming speed, age, weight, medical history and rehabilitation discipline all change both the timeline and the numbers achieved.
- 03The figures on this page are the general ranges the hospital publishes — not a guarantee and not an individual diagnosis. Only your own imaging can set your expected range.
- 04This site does not publish individual patient photographs. Ask the hospital directly at your consultation if you want to see comparison images or case radiographs.
Frequently asked questions
Why doesn't a normal X-ray show torsion?
A plain X-ray is a two-dimensional frontal image, so it shows angular deformity only. Torsion must be measured on CT or 3D imaging, which the institute uses alongside EOS for surgical planning.
When are the results of rotational deformity (in-toeing & out-toeing) visible?
Day of surgery: the bone is cut and realigned to the pre-planned angle, with the axis confirmed on intra-operative imaging. Similar to other realignment surgery, with no cast when internal fixation is used.
How is the before and after of rotational deformity (in-toeing & out-toeing) measured?
Deformity is quantified in degrees on standing full-leg weight-bearing radiographs, comparing the mechanical axis before and after surgery along with knee or ankle gap and rotational profile. The goal is an axis that passes back through the centre of the knee.
Is the result of rotational deformity (in-toeing & out-toeing) permanent, and what cannot be guaranteed?
Bone lengthening is major surgery. Outcome and recovery time depend on bone quality, age, weight and how disciplined the patient is with rehabilitation, so identical results cannot be guaranteed. Results differ from person to person: bone-forming speed, age, weight, medical history and rehabilitation discipline all change both the timeline and the numbers achieved.
