title: Comparative analysis of kinesiotherapy rehabilitation after hip arthroscopy, quantified by harris and vail hip scores: a retrospective study.
abstract: BACKGROUND
  It has been proven that femoroacetabular impingement cases improve following arthroscopic surgery. However, rehabilitation has a major role in the patient's recovery. The protocol used by our institution consists of an evidence-based guideline for the different phases of rehabilitation.
  
  
  OBJECTIVE
  Describe and determine the effectiveness of our institution's kinesiotherapy rehabilitation program during 2011-2016, comparing Harris and Vail Hip Scores scales (HHS and VHS, respectively) at the beginning of each treatment phase.
  
  
  METHODS
  This is an observational, descriptive, longitudinal and retrospective study which, from a total of 684 subjects who underwent surgery, and 103 subjects who followed our institution's rehabilitation program, ultimately uses a sample of 48 subjects for analysis; these subjects were included because they completed the scales on the three occasions determined.
  
  
  RESULTS
  Significant exact differences were found in: multivariate contrasts HHS (F=147.420; p=0.000); VHS (F=82,160; p=0,000). Mauchly's sphericity test: HHS (W=0.722; p=0.001); VHS (W=0.830; p=0.014). The within-subject effect showed significant exact differences in: HHS (F=169.451; p=0.000); VHS (F=115.387; p=0.000).
  
  
  CONCLUSIONS
  Results showed significant exact differences p=0.00. In spite of its limitations, this study provides a guideline for a patient's safe return to daily life activities.
