BACKGROUND: Hip pain remains a challenge given the multiple factors that can cause damage to the articular cartilage, such as traumatic injury, metabolic damage, and morphologic variations such as femoroacetabular impingement (FAI) and that can contribute to progression of osteoarthritis. However, a direct relationship between patient characteristics, the extent of acetabular chondral damage, and topologic characteristics of chondral lesions has not been established. PURPOSE: To compare the grade of acetabular chondral damage, measured in terms of acetabular labrum articular disruption (ALAD) classification, to the size and position of the chondral lesions, matching patients' demographic factors such as age and body mass index (BMI). STUDY DESIGN: Cross-sectional study; Level of evidence, 3. METHODS: This study included all hip arthroscopies performed by the corresponding author from August 7, 2008, to November 19, 2014, in which acetabular chondral lesions were intraoperatively identified and measured in terms of ALAD grade, clockface location, and size. Bivariate analyses and multiple logistic regression were used to identify the demographic factors, characteristics of the acetabular chondral lesion, and other anatomic characteristics that were related to the ALAD grade of the acetabular chondral lesion. RESULTS: Acetabular chondral lesions were measured in 1502 patients during the study period. Multivariate analysis showed that higher ALAD grade of acetabular chondral damage was significantly related to male sex, more advanced age, the area of the acetabular chondral lesion, anterior extension of the acetabular chondral lesion within the anterosuperior quadrant, labral detachment from the acetabular cartilage, and posterior extension of the labral tear. CONCLUSION: Higher grades of acetabular chondral damage were related to male sex, increased age, height, weight, BMI, and the size of the lesion. Chondral lesions were generally found in the anterosuperior region of the acetabulum, consistent with labral lesions and the weightbearing area of the acetabulum.
