Our indications and selection criteria for surgery were similar to those published in the literature and included non-inflammatory osteoarthritis, symptoms limited to only one compartment, intact anterior cruciate ligament, range of motion of 90° or more, no flexion contracture >5°, no more than a 15° angular deformity [3, 4, 5].
Angular malreduction was defined as more than 5° of angular deformity in either the coronal or sagittal plane [10, 18].
Malalignment was defined as any angular deformity of more than 5 degrees in the frontal plane or more than 10 degrees in the sagittal plane, unless otherwise mentioned in the article.
Although valgus angulation is reported to be the most frequent angular deformity [10], varus angulation was more common in our group of patients.
In osteoarthritis, the tibio-femoral joint space narrowing is often unsymmetrical, leading to angular deformity of the lower extremity, more commonly of varus type.
For a successful UKA, strict indications have been suggested, including an age of more than 60 years, low activity demand, no obesity, flexion contracture of less than 5 degrees, limited angular deformity, intact anterior cruciate ligaments, no OA in the contralateral compartment, and no patellofemoral pain (Kozinn and Scott 1989).
His face has grown more angular.

The magnitude of angular deformity is measured as 22° (A).
