Leg power, pelvic movement and physical activity after periacetabular osteotomy. A prospective cohort study.
Purpose To investigate changes in leg power, pelvic movement and patient-reported outcome in patients with hip dysplasia one year after periacetabular osteotomy. Â Â Â Â Â Â Â Â Methods Forty-one patients (7 males) with a mean age of 28.8 years scheduled for periacetabular osteotomy were tested before surgery, and 4 and 12 months after. Leg power, pelvic range of motion and the Hip and Groin Outcome Score (HAGOS) was collected.Results One year after surgery, power in the operated leg had improved (p=0.004) and there was no significant difference between power in the operated leg and contralateral leg (p=0.22). In the frontal plane, pelvic range of motion decreased significant during stair-climbing and stepping down. The same pattern was seen in the sagittal plane but the changes were non-significant. All subscales on the HAGOS improved significantly over time (p<0.001).Conclusion Leg power and pelvic range of motion in patients with symptomatic hip dysplasia improved 12 months after periacetabular
