Genu Varum
Conditions
Brief summary
The present study was conducted among a group of Iranian patients suffering from varus knee in order to compare advantages and disadvantages of ROWHTO (Retro-Tubercle Opening Wedge High Tibial Osteotomy) technique when compared with previously described approaches of opening-wedge osteotomy.
Detailed description
There are various methods for correcting varus deformity; therefore the best surgical method must be individualized. We concluded that in a varus knee where only correction in the coronal plane without patella infra, changes in Q- angle, tibial plateau inclination is all that is needed, a retro- tubercle medial opening- wedge osteotomy is the preferred approach.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| The proportion of patellar length (in mm)to the patellar tendon length (in mm) | up to 13 months | The length of the patella (in its longest diameter on a lateral x-ray) to the length of the patellar tendon is referred as Insall-Salvati index |
| The proportion of patellar articular surface length (in mm)to the patella-tibial plateau distance (in mm) | up to 13 months | The length of the articular surface of the patella to the distance from the patella to the tibial plateau is referred as Blackburne-Peel index. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Quadriceps angle in degree | up to 13 months | The angle between the quadriceps vector and the line of pull of the patellar tendon from the centre of the patella to the tibial tubercle. |
| Inclination of proximal tibial plateau in degree | up to 13 months | The angle between articular surface and lateral longitudinal axis of tibia. |
