Background
Hip osteoarthritis (OA) remains a major source of morbidity, and identifying modifiable or predictive anatomical risk factors is key for early intervention. This systematic review evaluated radiographic characteristics linked to the development and progression of hip OA.
Methods
A comprehensive review of literature was conducted to identify radiographic features associated with hip OA. Factors such as acetabular coverage and cam morphology were among the primary anatomic markers analyzed.
Key Findings
- Acetabular under-coverage and cam-type femoroacetabular impingement (FAI) were strongly associated with OA onset and progression.
- These radiographic abnormalities often precede clinical symptoms and can guide early intervention strategies.
- Other contributors included joint space narrowing, osteophyte formation, and femoral head asphericity.
Conclusions
Certain radiographic parameters, particularly acetabular under-coverage and cam deformity, are reliable predictors of future OA. Early recognition via standard imaging can allow providers to implement targeted interventions aimed at preserving joint health.
What Does This Mean for Providers?
Clinicians should routinely evaluate for acetabular under-coverage and cam morphology in at-risk populations, especially younger, active patients. Early identification enables preventative strategies or timely surgical consultation to potentially delay OA progression and improve long-term outcomes.
