Deformity correction
Osteotomy for knee arthritis before & after — Dr. Donghoon (DALRI)
Once surgery and the full recovery period are complete, what changes is: Preserves the native knee — no implant joint · Addresses pain and leg shape together
Before: what is recorded
Before surgery the team documents the starting point of everyone considering osteotomy for knee arthritis — Medial compartment arthritis with bowleg alignment in younger patients · Patients wanting to postpone total knee replacement — 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.
- 02Weight-bearing is increased progressively to instruction until union is complete.
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
How long does the correction last?
It depends on the existing wear, body weight and activity. The goal is pain relief and deferring replacement by years; suitability is assessed individually.
When are the results of osteotomy for knee arthritis visible?
Day of surgery: the bone is cut and realigned to the pre-planned angle, with the axis confirmed on intra-operative imaging. Weight-bearing is increased progressively to instruction until union is complete.
How is the before and after of osteotomy for knee arthritis 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 osteotomy for knee arthritis 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. The 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.
