Outcomes and subjective assessment of rotation-plasty in patients with proximal femoral focal deficiency.

This study presents outcomes of rotation-plasty for unilateral proximal femoral focal deficiency in the adolescent population. The function, timing of knee fusion, and complications were presented as well as patients' assessment of their function and appearance. Eight patients, aged 8.37 years (range: 3-16 years) during surgery, were evaluated. The mean follow-up duration was 9.25 years (range: 6-12 years). At follow-up, all the patients were pain free and able to ambulate outdoors. Complications included derotation of the foot in five patients, necessitating a re-rotation osteotomy in two. All patients accepted their appearance, considering the rotation-plasty beneficial for their functional status.
