Nevertheless, contemporary diagnostic tools have significant limitations in predicting severity of disease preoperatively.<\/jats:p>\n                  <jats:p>Hypothesis: Clinical characteristics and radiographic parameters correlate with and predict intra-articular disease patterns in patients undergoing hip arthroscopy.<\/jats:p>\n                  <jats:p>Study Design: Cohort study; Level of evidence, 3.<\/jats:p>\n                  <jats:p>Methods: In sum, 355 hips in 338 patients undergoing hip arthroscopy by a single surgeon were retrospectively reviewed. Clinical characteristics and radiographic findings (on anteroposterior pelvis and frog lateral radiographs) of mild dysplasia, cam, and pincer-type femoroacetabular impingement were compared with intraoperative labral and chondral disease patterns.<\/jats:p>\n                  <jats:p>Results: Labral tears were present in 90.1% of hips, and acetabular cartilage lesions were present in 67.3%, including 41.7% with grade 3 or 4 chondromalacia. Multivariate logistic regression analysis found male sex, older age (&lt;30, 30-50, &gt;50 years old), T\u00f6nnis osteoarthritis grade, and alpha angle &gt;50\u00b0 on frog lateral radiograph to be independently associated with increased risk of grade 3 or 4 acetabular chondromalacia (all P &lt; .001). Insidious onset of pain (in contrast to acute onset) was independently associated with the presence of acetabular chondromalacia ( P = .002). Cam-type femoroacetabular impingement (alpha angle &gt;50\u00b0) was strongly associated with more severe labral disease ( P &lt; .001). Findings of acetabular dysplasia and pincer femoroacetabular impingement did not remain significantly associated with acetabular chondral disease in the multivariate analysis.<\/jats:p>\n                  <jats:p>Conclusion: Several clinical and radiographic characteristics\u2014most notably, male sex, older age, T\u00f6nnis grade, and elevated alpha angle\u2014are associated with more severe intra-articular hip disease. The recognition of these associations between clinical and radiographic characteristics and hip disease patterns is important for patient selection, surgical planning, and patient counseling.<\/jats:p>","DOI":"10.1177\/0363546510384787","type":"journal-article","created":{"date-parts":[[2010,11,24]],"date-time":"2010-11-24T00:02:00Z","timestamp":1290556920000},"page":"296-303","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":124,"title":["Clinical
