Arthroscopy for Labral Tears in Patients with Developmental Dysplasia of the Hip: A Cautionary Note
Section snippets
Patient Population
This study from 2 institutions identified all patients with morphologic abnormality of the hip who had undergone hip arthroscopy for the repair and/or excision of the labrum. The cohort consists of 34 patients (36 hips), 22 women and 12 men, with a mean age of 34 years (range, 19-51 years) at the time of arthroscopy. All surgeries were performed at university-affiliated institutions where detailed electronic data are collected in a prospective manner. The clinical and radiographic records of
Results
Radiographic evaluation confirmed the presence of morphologic abnormalities of the hip in all cases, with DDH in 30 hips and acetabular retroversion in 6 hips. Femoroacetabular impingement (due to an underlying abnormal morphology of the acetabulum and/or femoral head) was present in 7 hips. Magnetic resonance arthrogram confirmed the presence of labral tears and/or degeneration in all cases.
All patients were followed clinically and radiologically for at least 1 year after arthroscopy. No
Discussion
Developmental dysplasia of the hip is a relatively common condition that, depending on the geographic location, can be seen in up to 80% of patients with end-stage arthritis of the hip [9]. Because of decreased surface area of contact and increased joint reaction forces, patients with dysplasia ultimately develop arthritis of the hip and seek hip arthroplasty. Patients with DDH may also come to the attention of orthopedic surgeons because of the presence of labral pathologies and/or chondral
