Decreased joint space, increased time from symptom onset to arthroscopy, male gender and larger alpha angles associated with femoroacetabular impingement were linked with grade IV chondral defects in patients undergoing hip arthroscopy, according to results.
Researchers identified 1,097 adult patients who underwent hip arthroscopy for pain between June 2006 and June 2010. Patients had no prior hip surgery. Researchers used preoperative radiographs, patient demographic characteristics and operative details to identify risk factors for cartilage defects.
Results showed 28% of hips had grade IV chondral defects. Researchers observed isolated chondral lesions more frequently on the acetabulum vs. the femoral head, and defects of the acetabulum were anterosuperior in 94.7% of cases compared with posterolateral in 5.3% of cases. Patients were eight-times more likely to have a grade IV lesions if they had less than 2 mm of joint space on preoperative radiographs vs. more than 2 mm of joint space, according to results. Researchers also found grade IV lesions were more commonly seen among men, older patients, patients with hips with significantly larger alpha angles and patients who had a longer duration of symptoms. – by Casey Tingle
