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.
