Study Arms (1)

Hip Dysplasia group

Subjects who have undergone a periacetabular osteotomy (PAO) for hip dysplasia within the last 1-5 years.

Other: Testing of physical capacity

Interventions

This cross-sectional study will involve evaluation of physical capacity by assessment of: 1. Gait function 2. Muscle activity during walking 3. Endurance during walking 4. Hip muscle strength 5. Hip range of motion 6. Hip and muscle-tendon-related groin pain 7. Hip and groin related patient-reported outcome measures (PROMs)

Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64)
Sampling MethodNon-Probability Sample
Study Population

Subjects who have undergone a periacetabular osteotomy (PAO) for hip dysplasia within the last 1-5 years. Subjects will be recruited through social media from two specific closed-member facebook groups for patients with hip dysplasia. Permission for recruiting through social media was granted by The Danish Data Protection Agency along with permission for the handling of personal data (P-2020-261).

You may qualify if:

  • Age 18 to 40 years
  • BMI \< 30
  • Primary diagnosis of ipsilateral or bilateral hip dysplasia
  • Treated with PAO for hip dysplasia unilaterally or bilaterally within 1-5 years

You may not qualify if:

  • Retroverted acetabulum (positive posterior wall sign and ischial spine sign) treated with reversed PAO
  • Total Hip Arthroplasty (THA)
  • Pain management with analgesics or other medication affecting muscle function and perception of pain
  • A need for walking aids to be able to walk freely
