Background: The influence of femoral torsion on clinically significant outcome improvement after hip arthroscopy for femoroacetabular impingement syndrome (FAIS) has not been well-studied. Purpose: To quantify femoral torsion in FAIS patients using magnetic resonance imaging (MRI) and explore the relationship between femoral torsion and clinically significant outcome improvement after hip arthroscopy. Study Design: Cohort study; Level of evidence, 3. Methods: Included were patients who underwent hip arthroscopy for FAIS between January 2012 and August 2018 and had 2-year follow-up and preoperative MRI scans containing transcondylar slices of the knee. Participants were categorized as having severe retrotorsion (SR; <0°), normal torsion (NT; 0°-25°), and severe antetorsion (SA; >25°) as measured on MRI. Patient-reported outcomes (PROs) included the Hip Outcome Score–Activities of Daily Living, Hip Outcome Score–Sports Subscale, modified Harris Hip Score, 12-item International Hip Outcome Tool (iHOT-12), and visual analog scale (VAS) for pain and satisfaction. Achievement of Patient Acceptable Symptom State (PASS) and substantial clinical benefit (SCB) were analyzed among cohorts. Results: Included were 183 patients (SR, n = 13; NT, n = 154; SA, n = 16) with a mean age, body mass index, and femoral torsion of 30.6 ± 12.1 years, 24.0 ± 4.4 kg/m2, and 12.55° ± 9.58°, respectively. The mean torsion was –4.5° ± 2.6° for the SR, 12.1° ± 6.8° for the NT, and 31.0° ± 3.6° for the SA group. There were between-group differences in the proportion of patients who achieved PASS and SCB on the iHOT-12, pain VAS, and any PRO ( P < .05). Post hoc analysis indicated that the SA group achieved lower rates of PASS and SCB on the iHOT-12 and pain VAS, and lower rates of PASS on any PRO versus the SR group ( P < .05); the SR group achieved higher rates of PASS and SCB on pain VAS scores versus the NT group ( P = .003). Conclusion: The orientation and severity of femoral torsion during hip arthroscopy influenced the propensity for clinically significant outcome improvement. Specifically, patients with femoral retrotorsion and femoral antetorsion had higher and lower rates of clinically significant outcome improvement, respectively.

Objectives: Patient satisfaction is being increasingly reported in orthopaedic sports medicine and the field of hip preservation surgery. The Visual Analog Scale (VAS) for Satisfaction is most commonly utilized. Currently there is limited understanding for what should be considered as clinically important improvement on the VAS Satisfaction. The purpose of this study is to 1) define Substantial Clinical Benefit (SCB), Patient Acceptable Symptomatic State (PASS), and Minimal Clinically Important Difference (MCID) for the VAS Satisfaction in patients undergoing hip arthroscopy for femoroacetabular impingement syndrome (FAIS), and 2) identify preoperative predictors of achieving each outcome end-point. Methods: Data from consecutive patients who underwent primary hip arthroscopy between November 2014 and January 2017 were collected and analyzed. Baseline data and postoperative patient-reported outcome (PRO) scores were recorded at 2-years postoperatively. In order to quantify clinical significance of outcome achievement on the VAS Satisfaction we calculated MCID, PASS and SCB for this outcome measure. A multivariate logistic regression analysis was used to identify preoperative predictors of achieving SCB, PASS, and MCID satisfaction. Results: A total of 335 patients were included in the final analysis, with an average age and body mass index (BMI) of 32.8(SD+12.4) years and 25.2(SD+5.3) respectively. The values on the VAS satisfaction were identified to represent MCID, PASS and SCB respectively: 12.3, 80.9 and 89.7. The rates of achieving clinically significant improvement on the VAS Satisfaction was 97.1%, 68.1% and 56.9% for MCID, PASS and SCB respectively. A larger preoperative alpha angle was predictive for achieving SCB (OR:1.076; p =0.046), while lower BMI (OR:0.955; p =0.047) and larger preoperative alpha angle (OR:1.12; p-value=0.025) were predictors for achieving PASS. Conclusions: This study identifies scores on the VAS Satisfaction that can be used to define clinically significant outcome after arthroscopic treatment of FAIS. Specifically, an improvement of 12.3 points is a clinically important improvement in satisfaction, while an absolute score above 89.7 represents the upper threshold of Satisfaction performance. Almost all patients (97.1%) demonstrated a clinically important improvement in satisfaction. Additionally, there are both modifiable and non-modifiable factors that predict achieving a clinically significant level of post-operative satisfaction on the VAS Satisfaction.
