Correlation of Single Assessment Numerical Evaluation Score for Sport and Activities of Daily Living to Modified Harris Hip Score and Hip Outcome Score in Patients Undergoing Arthroscopic Hip Surgery.
BACKGROUND
The Single Assessment Numerical Evaluation (SANE) is a single-question outcome score that has been shown to be a reliable measure of outcomes for shoulder and knee injuries but has not been compared with other validated outcome scores in hip pathology managed arthroscopically.


PURPOSE
To correlate SANE Activities of Daily Living (ADL) and Sport subscales with the modified Harris Hip Score (mHHS) and Hip Outcome Score (HOS) ADL and Sport subscales before and after arthroscopic hip surgery.


STUDY DESIGN
Cohort study (diagnosis); Level of evidence, 3.


METHODS
A retrospective review of a prospectively filled database of patients undergoing arthroscopic hip surgery by a single surgeon was conducted. Inclusion criteria included patients scheduled for arthroscopic hip surgery for femoroacetabular impingement, labral tear, or gluteus medius tear. Exclusion criteria included previous surgery to the hip. Outcome scores, including the mHHS, HOS ADL and Sport, and SANE ADL and Sport, were measured preoperatively and postoperatively at 3 months, 1 year, and then annually. Pearson correlation coefficients between preoperative SANE ADL and Sport and the mHHS, HOS ADL, and HOS Sport were calculated. Pearson correlation coefficients between postoperative SANE ADL and Sport and the mHHS, HOS ADL, and HOS Sport were also calculated.


RESULTS
Eighty-five patients (mean age, 37.9 years; range, 14-66 years; 57 females, 28 males) underwent arthroscopic hip surgery for assorted pathology. Mean follow-up was 8 months (range, 3-64 months). Based on the Pearson correlation coefficient, preoperative SANE ADL and Sport had a moderate correlation with the mHHS (r = 0.66; 95% CI, 0.47-0.79; P < .0001; r = 0.54; 95% CI, 0.31-0.71; P < .0001, respectively). Preoperative SANE ADL and Sport had a moderate correlation with HOS ADL (r = 0.60; 95% CI, 0.39-0.75; P < .0001) and HOS Sport (r = 0.65; 95% CI, 0.45-0.79; P < .0001). Postoperative SANE ADL and Sport had a strong correlation with the mHHS (r = 0.69; 95% CI, 0.50-0.82; P < .0001; r = 0.78; 95% CI, 0.61-0.88; P < .0001). Postoperative SANE ADL and Sport had a strong correlation with HOS ADL (r = 0.79; 95% CI, 0.65-0.88; P < .0001) and HOS Sport (r = 0.88; 95% CI, 0.78-0.94; P < .0001).


CONCLUSION
This study showed a significant correlation between SANE and mHHS in patients undergoing arthroscopic hip surgery both pre- and postoperatively. SANE ADL and Sport had a strong correlation with HOS ADL and Sport preoperatively and short-term postoperatively. SANE scores are more highly correlated with traditional subjective outcome measures during the short-term postoperative period than they are preoperatively. The SANE score provides an efficient method of assessing outcomes after hip arthroscopy.
