Preoperative Expectations Do Not Correlate With Postoperative iHOT-33 Scores and Patient Satisfaction Following Hip Arthroscopy for the Treatment of Femoroacetabular Impingement Syndrome

Purpose: To examine the correlation between preoperative patient expectation and International Hip Outcome Tool (iHOT-33) score and postoperative satisfaction of patients undergoing hip arthroscopy for the treatment of femoroacetabular impingement syndrome. Methods: Patients scheduled for surgery completed the Hip Preservation Surgery Expectations Survey (HPSES), as well as the preoperative and a minimum 2-year postoperative iHOT-33. Patient demographics that were collected included gender, age, occupation, and body mass index (BMI). At the latest follow-up, patients were evaluated for their subjective satisfaction and postoperative complications. An in-depth analysis was performed to assess the correlation between HPSES, iHOT-33, and patient satisfaction. Results: Sixty-nine patients (62.3% males; mean age: 33.7 +/- 13.1 years; BMI: 23.9 +/- 3.5 kg/m2) were included in this study. The mean HPSES score was 83.8 +/- 16.5. The mean iHOT-33 improved from 31.6 +/- 15.8 preoperatively to 73 +/- 25.9 postoperatively (95% CI = 35.2,47.8; P < .01), and the mean patient satisfaction was 75.9 +/- 26.9. There were no statistically significant differences in mean HPSES score between males and females (95% CI = 79.9,87.8; P = .35) nor between different occupational groups (95% CI = 79.4,87.6, P = .095). No correlation was found between age and HPSES score (r = .036; P =.76). There was a negligible correlation between HPSES score and postoperative iHOT-33 score (r = -.117; P = .34) and patient satisfaction (r = -.042; P = .73). Postoperative iHOT-33 score had a significant high correlation with patient satisfaction (r = .8; P < .001). Conclusion: Preoperative expectations do not correlate with postoperative iHOT-33 scores and patient satisfaction with surgery at 2 years after surgery. Gender and occupation did not differ significantly with regard to preoperative expectations, and there was no correlation between age and HPSES score. Level of Evidence: IV, retrospective case series.
