Abstract :
Background: Osteoarthritis (OA) is a highly prevalent chronic degenerative joint disease with different risk factors, which need to
be investigated in order to perform more appropriate interventions in earlier phases of Osteoarthritis.
Objectives: Therefore, the aim of this study was to determine the correlation between hip morphology and hip Osteoarthritis.
Methods: This cross-sectional study was conducted on patients aged 15 to 60 years old with hip problems, diagnosed with hip Osteoarthritis,
comparedwith healthy individuals as the controlgroup. Thenradiographic parameters, such as alpha angle, acetabular
angle of sharp (AA), lateral center-edge angle (LCEA), femoral neck-shaft angle (FNA), coxa profunda, acetabular protrusio, crossover
sign, posterior wall sign, and the ischial sign were measured by pelvic (AP) X-ray, using PACS systems in both groups.
Results: This study found that alpha angle and AA were significantly greater in OA patients as compared to healthy individuals
(P < 0.001). Furthermore, LCEA was significantly greater in the Osteoarthritis group on the left side as compared to the control
group (38.938.43 versus 36.814.74, P = 0.042) yet LCEA on the right side and total amount were not different between the two
groups (P>0.05). By grouping studied angles, it was found that the frequency of alpha angle > 55°, AA > 38°, and LCEA > 40° were
significantly higher in theOAgroup as compared to the control group (P< 0.05). Furthermore, the researchers observed that the frequency
of acetabular protrusio (P = 0.013) and posterior wall sign were significantly higher in the OA group as compared to healthy
individuals (P < 0.05).
Conclusions: The current results showed that the higher Body Mass Index (BMI), greater alpha and acetabular angles, sharp, lateral
center-edge angle center-edge angle, the higher rate of a posterior wall sign, and acetabular protrusio increased the risk of OA, which
support that these structural changes are major contributors to OA development.
