Movement Pattern in Patients With Hip Dysplasia
Movement Pattern in Patients With Hip Dysplasia
The purpose of this study is to examine the movement pattern in patients with hip dysplasia
 preoperative, six and 12 month after minimally invasive approach for Periacetabular osteotomy
 (PAO). Secondary to examine the movement pattern in patients compared to healthy controls and
 historical data.
Congenital hip dysplasia is a disease characterised by pathological changes in the hip joint.
 Hip dysplasia is a normal disease with a prevalence of 4.3% in men and 3.6 in woman.
 Untreated hip dysplasia is a known cause of developing osteoarthritis early in life and
 symptoms as pain, hip instability together with a changed gait pattern are normal.
 Symptomatic hip dysplasia is seen in patients between 15 and 55 years and can be unilateral
 as well as bilateral. Causes of hip dysplasia are described as genetic, mechanic or hormonal.

 Today patients with hip dysplasia are offered a hip conserving surgery before the
 osteoarthritis has developed. In 2003 a minimally invasive approach for periacetabular
 osteotomy (PAO) was introduced at Aarhus University Hospital. An advantage of minimally
 invasive approach compared to the classical Bernese periacetabular osteotomy is minimal
 impact of the soft tissues in the hip region.

 Hip pain and activity limitations highly affect quality of life and physical function. The
 gait distance is reduced and patients have to compensate to relieve the pressure on the hip
 joint. Knowledge about the dynamics of the gait and running pattern in patients with
 dysplasia is important to understand the consequences of the dysplastic hip joint.
 Furthermore knowledge about gait compensations is relevant for the clinicians in the
 management and treatment of patients with hip dysplasia.

 Today, gait and running compensation is unknown after minimally invasive approach The purpose
 of this study is, therefore, to examine the movement pattern in patients with hip dysplasia
 preoperative, six and 12 month after minimally invasive approach for Peri-acetabular
 osteotomy (PAO). Secondary to examine the movement pattern in patients compared to healthy
 controls and historical data.
