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.
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.

The proportion of patellar length (in mm)to the patellar tendon length (in mm)
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
Time frame: up to 13 months
The proportion of patellar articular surface length (in mm)to the patella-tibial plateau distance (in mm)
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.
Time frame: up to 13 months
Quadriceps angle in degree
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.
Time frame: up to 13 months
Inclination of proximal tibial plateau in degree
The angle between articular surface and lateral longitudinal axis of tibia.
Time frame: up to 13 months
