Hip dysplasia is one of the most common causes of hip pain in athletes in the Asian population.1 Athletes with hip dysplasia typically present with groin and lateral hip pain, which is associated with intra-articular pathologies, including labral tear and cartilage damage. Numerous studies have demonstrated that the anterosuperior and superolateral shallow acetabulum can cause repetitive overloading, resulting in labral tearing, cartilage damage, and sometimes rim stress fracture, which predispose them to osteoarthritis. In addition, many patients with hip dysplasia also present with groin and lateral hip pain that can result from chronic fatigue overload of the periarticular musculotendon structures, including the gluteus maximus, Ilio Tibial (IT) band, rectus femoris, and ilopsoas tendon snapping issues. Hip dysplasia has been better defined as being closely linked with hypermobile sports activities such as rhythmic gymnastics, figure skating, and ballet.2 Another study has shown that throwing athletes (baseball players) also have hip dysplasia in 7.9% and borderline hip dysplasia in 15.9%.3 Recent studies have emerged indicating that cam deformities often coexist with developmental dysplasia of hip (DDH).4
Advances in Adult Dysplasia

The term ‘hip dysplasia’ includes a wide variety of pathomorphologic disorders that usually occur due to a delay in the growth and development of the hip, and mainly the acetabulum. The pathologic disorder is a dynamic and mechanical process that would result in insufficient coverage of the head by the acetabulum and joint instability [1].
Hip dysplasia is not uncommon but frequently overlooked: a cross-sectional study based on radiographic examination of 1,870 adults

We investigated whether or not the hip dysplasia was detected during radiographic examination in standard care. To our knowledge, this has not been previously studied. Our results suggest that a vast majority of hip dysplasia cases may be overlooked by Swedish radiologists. Underreading error has been shown to be among the most common of radiological errors, and delayed diagnosis due to radiological errors is most frequent in the musculoskeletal section (Kim and Mansfield 2014). In the current aspect, underreading of hip dysplasia may be reduced by education and raised awareness of the diagnosis among radiologists. Another important factor is for the referring clinician to ask for signs of dysplasia in relevant cases, i.e., awareness of the diagnosis needs to be increased amongst general practitioners and orthopedic surgeons as well.
The effects of locomotor training in children with spinal cord injury: a systematic review

LT has the potential to decrease secondary complications that result from SCI in childhood. The majority of children in a review study completed by Schottler et al. (2012) demonstrated that children with SCI developed scoliosis if they had a complete injury. Hip dysplasia also occurred in 57% children. Bracing and seating are typical adaptations used for children, but these interventions may not be sufficient.51 Increased upright mobility, including LT, can potentially decrease these complications. Research has shown that individuals who ambulate are less likely to develop hip dysplasia or more severe scoliotic curves, reducing secondary impairments that occur in children following SCI.52
Correspondence: Isometric hip strength impairments in patients with hip dysplasia are improved but not normalized 1 year after periacetabular osteotomy: a cohort study of 82 patients

Second, 89 patients with bilateral hip dysplasia were recruited in this study. However, inclusion of bilateral hip dysplasia patients may also lead to bias. Previous studies showed that the hip muscle strength of the contralateral hip joint in patients with unilateral femoroacetabular impingement syndrome (Malloy et al. 2019) or hip osteoarthritis (Arokoski et al. 2002, Diamond et al. 2016) will also be affected. We firmly believe that this condition can also occur in patients with hip dysplasia. However, side differences of hip muscle strength between affected and contralateral leg were not analyzed bilaterally in patients affected with hip dysplasia.
