Acetabular dysplasia and the risk of developing hip osteoarthritis within 4-8 years: An individual participant data meta-analysis of 18,807 hips from the World COACH consortium.

Objective: To study the association between various radiographic definitions of acetabular dysplasia (AD) and incident radiographic hip osteoarthritis (RHOA), and to analyze in subgroups.

Methods: Hips free of RHOA at baseline and with follow-up within 4-8 years were drawn from the World COACH consortium. The Wiberg center edge angle (WCEA), acetabular depth width ratio (ADR), and the modified acetabular index (mAI) were calculated.

Metabolic syndrome is associated with poorer outcomes in people with osteoarthritis participating in a rehabilitation program: an observational study.

Purpose: To determine the prevalence of metabolic syndrome and explore its association with clinical outcomes (pain, quality of life, and physical function) in adults participating in an education and exercise program (GLA:D).

Methods: An observational study of adults with hip and/or knee osteoarthritis who participated in GLA:D between 2019 and 2022. Metabolic syndrome status was determined through self-report.

Relationship Between Hip and Groin Pain and Hip Range of Motion in Amateur Soccer and Australian Rules Football Players.

Background: The relationship between hip/groin pain and hip range of motion (ROM) is unclear.

Purpose: To explore the relationship between hip/groin pain and hip joint ROM and examine the influence of sex and cam morphology on this relationship.

Study Design: Cross-sectional study; Level of evidence, 3.

Muscle Fat and Volume Differences in People With Hip-Related Pain Compared With Controls: A Machine Learning Approach.

Background: Hip-related pain (HRP) affects young to middle-aged active adults and impacts physical activity, finances and quality of life. HRP includes conditions like femoroacetabular impingement syndrome and labral tears. Lateral hip muscle dysfunction and atrophy in HRP are more pronounced in advanced hip pathology, with limited evidence in younger populations.

Reliability and agreement of manual and automated morphological radiographic hip measurements.

Objective: To determine the reliability and agreement of manual and automated morphological measurements, and agreement in morphological diagnoses.

Methods: Thirty pelvic radiographs were randomly selected from the World COACH consortium. Manual and automated measurements of acetabular depth-width ratio (ADR), modified acetabular index (mAI), alpha angle (AA), Wiberg center edge angle (WCEA), lateral center edge angle (LCEA), extrusion index (EI), neck-shaft angle (NSA), and triangular index ratio (TIR) were performed.
