title: Improved functional outcome with no decrease in hip strength 2 years following Ganz periacetabular osteotomies for adolescent hip dysplasia.
abstract: To analyze outcomes of adolescents treated with a periacetabular osteotomies (PAO) with a minimum of 2 years of follow-up. Patients undergoing a PAO for adolescent hip dysplasia were analyzed preoperatively, 1 and 2 years postoperatively. In 32 dysplastic hips significant improvement was seen in all radiographic parameters. Gait speed, hip flexion pull-off power, and hip abductor moment impulse were unchanged postoperatively, whereas strength was maintained in 85% (abduction) and 95% (flexion). The Harris Hip Score increased from 67.1 to 77.9 to 81.3 at 1 and 2 years, respectively. Ganz PAO is effective in correcting dysplasia in adolescents radiographically and functionally.
