[Arthroscopic treatment of acetabular labrum lesions: a series of 12 patients with a 4-year follow-up]. / Traitement arthroscopique des lésions du labrum acétabulaire. A propos de 12 patients avec un recul moyen de 4 ans.

PURPOSE OF THE STUDY: The aim of this work was to report our experience with arthroscopy for the treatment of acetabular labral lesions and identify prognostic factors determining mid- and long-term outcome. MATERIAL AND METHODS: Between August 1991 and December 1997, 12 patients (ten women, two men, mean age 39 years, age range 25-61 years) underwent arthroscopic treatment of an acetabular labrum lesion. All were reviewed at a mean 4 years follow-up (18 months-8 years). Half of the patients (n =6) had a history of hip surgery: two femoral osteotomies and one acetabular bone block for congenital hip dislocation, two high-energy traumas and one traumatic dislocation. Clinical manifestations including pain (n =12), a sensation of a snag (n =10), or blockage (n =8) had developed over a mean 15 months (2-24 months). Standard x-rays evidenced early signs of degenerative disease in four cases and acetabular dysplasia in four (5 degrees
