Paper 20: The Outcome of Arthroscopic Treatment for Cam Type Femoroacetabular Impingement in Adolescents


      Arthroscopic femoral osteochondroplasty was performed in 34 consecutive patients under the age of 18 years with excellent outcome and no significant complications.



      Hip arthroscopy has become an established procedure in adults with well published results. These techniques have been extended to the teenage population, but the literature remains limited in regards to indications, efficacy, outcomes and complications specific to the paediatric population.


      The purpose of this study was to report the short-term outcome of the arthroscopic treatment of cam-type femoroacetabular impingement (FAI) in the adolescent population.

      Study Design

      multi-center prospective longitudinal case series.


      From 2008-2009, 34 consecutive patients who were 18 years or younger at the date of operation (41 hips) had arthroscopic hip surgery for treatment of cam-type FAI and associated lesions by use of the lateral decubitus position by two surgeons.
      Data was collected prospectively including the modified Harris Hip Score (MHHS), Nonarthritic Hip Score (NAHS), satisfaction survey and complications. Mean followup was 14 months (range 1-2 years)


      All hips were available for review. The mean age of patients was 15.7 years with the most common sport activity being AFL, netball and rugby. All patients had cam-type impingement, with the most common associated lesions being acetabular rim lesions (82.9%) and pincer impingement (22%). The labrum underwent debridement in 31.7% of cases, and was repaired in 17.1%. The MHHS and NAHS improved in all patients postoperatively, 77.39 to 94.15 and 76.34 to 93.18 respectively. 78.1% were able to return to full sporting activity and 88.2% were satisfied 30 with the operation.
      There were no complications.


      Using hip arthroscopy to treat cam-type impingement and associated lesions in the adolescent population, we observed high satisfaction levels, return to sports, and significant improvement in postoperative hip scores (MHHS and NAHS). There were no complications related to operating on the cam lesion in the presence of open proximal femoral growth plates.
