title: Arthroscopic treatment of femoroacetabular impingement in patients older than 60 years.
abstract: BACKGROUND
  The indications of hip arthroscopy increased over the past decade. Although mostly recommended for treatment of femoroacetabular impingement (FAI) in young patients, well-selected older patients (> 60 years old) may benefit from this surgery. However, the role of hip arthroscopy for the management of older patients is controversial. The aim of the study is to evaluate the clinical outcomes of a series of patients aged 60 years and older who underwent hip arthroscopy for FAI at mid-term follow-up.
  
  
  METHODS
  Sixty-year-old patients and older, with a joint space greater than 2 mm, and a grade I and II hip osteoarthrosis (OA) according Tönnis scale were included into the study. Twenty-three patients (28 hips) met the inclusion criteria. The T-Student test was used to detect for differences between variables (p<0.05).
  
  
  RESULTS
  The mean age of the patients was 63.4 years, and the mean follow-up was 4.4 years (2-9 years). We found an improvement in mHHS and VAS score from the baseline to the final follow-up in 87% of patients (p<0.05). Three patients (13%) were submitted to a THA at a mean of 12 months, while the survivorship rate at the final follow-up was 75%. No major complications have been reported.
  
  
  CONCLUSIONS
  Arthroscopic treatment of FAI in patients over 60 years old, with no signs of advanced osteoarthrosis, showed a significant improvement of functional score and pain in most of cases, and it can be consider a reasonable option in well selected patients. Level of evidence: IV case series.
