Outcome Measures
Primary Outcomes (2)
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
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.
up to 13 months
Secondary Outcomes (2)
Quadriceps angle in degree
up to 13 months
Inclination of proximal tibial plateau in degree
up to 13 months
Study Arms (1)
Medial Opening-Wedge Osteotomy
EXPERIMENTALMedial Opening-Wedge Osteotomy (MOWO) is an approach for the correction of malalignment of the knee
Interventions
Retro-Tubercle Opening-Wedge High Tibial Osteotomy (ROWHTO) is among the latest approaches for the treatment of varus deformity of knee.
Eligibility Criteria
You may qualify if:
- symptomatic varus deformity of the knee with 2 or more degrees of anatomical axis varus without ligament injury
You may not qualify if:
- fractures through compartments of the knee or the patella
- osteoarthritis other than in the medial compartment
- degrees or more extension lag
- tibial malrotation
