Abstract
Abstract Purpose To evaluate the impact of symptom duration on predicting intra-articular cartilage damage in patients undergoing primary hip arthroscopy. Methods Data were prospectively collected for all patients who underwent primary hip arthroscopy for femoroacetabular impingement (FAI) between February 2008 and October 2022. Exclusion criteria included prior revision arthroscopy, Tönnis grade ≥2, LCEA less than 25°, or a history of acute injury. Symptom duration was defined as the time in months since the onset of pain to the date of surgery. Acetabular cartilage severity was assessed intraoperatively during the diagnostic portion of the procedure and classified using the Outerbridge grading system, with grades 3–4 classified as severe. Univariate and multivariate regression analyses were performed to evaluate associations between relevant demographic variables and severe intra-articular pathology. Results A total of 2602 patients were included in the study with a mean age of 37.1 ± 14.6, mean BMI of 26.1 ± 5.36, and mean symptom duration of 24.0 ± 33.0 months. 36.0% of the cohort were male. Univariate analysis showed significant (p<0.05) associations between higher grade acetabular cartilage damage and longer symptom duration, higher BMI, older age, male sex, and lower Beighton’s score, while smoking status and sports participation were not. Multivariate logistic regression analyses demonstrated significant associations between severe acetabular chondral pathology and longer symptom duration (OR 2.01 95% CI 1.003-4.33 p=0.04), older age (OR 2.97, 95% CI 2.38-3.70, p<0.0001), higher body mass index (BMI) (OR 1.28, 95% CI 1.11–1.47; p<0.001), male sex (OR 4.56, 95% CI 3.52–5.91; p<0.0001), and elite sports participation (OR 1.64, 95% CI 1.09–2.47; p=0.02). Conclusions Longer symptom duration was associated with severe acetabular cartilage damage in patients undergoing primary hip arthroscopy, in addition to established demographic and clinical risk factors including older age, higher BMI, and male sex. These findings suggest that delayed presentation may be associated with more advanced intra-articular pathology at the time of surgery, and earlier diagnosis may enable treatment before severe acetabular cartilage damage occurs.
