High tibia osteotomy for early medial knee arthritis is a surgical intervention that shifts the mechanical axis from the medial to the lateral side of the knee joint, thereby unloading the medial early degenerative knee compartment by shifting the force/area from the medial compartment to the lateral outer 1/3 of the knee joint.
Patient suitable for osteotomy include:
- ≤ 60 – 65 years
- ≤ Grade I or II unicompartmental osteoarthritis
- Range of motion ≥ 90º
- Flexion deformity of <15º
- Mechanical axis deviation <15º
This intervention is also an augment to address knee instability
Ideal for the relatively young active individual with early medial knee arthritis that meets the osteotomy criteria (Feeley B T et al)
