Abstract
Abstract Background Prior to surgical treatment with hip arthroscopy for femoroacetabular impingement (FAI), intraarticular steroid injections of the hip are often used as a diagnostic and therapeutic modality. Recent literature has demonstrated injection responders and nonresponders demonstrate similar outcomes following hip arthroscopy at both mid- and long-term follow-up. However, factors associated with patient satisfaction following hip arthroscopy specifically in injection non-responders has not previously been reported. Methods All patients undergoing primary hip arthroscopy for the treatment of femoroacetabular impingement syndrome (FAIS) and/or labral tears with history of nonresponse to intraarticular injection treatment (defined as self-reported <50% relief) were included. Patients were divided into 2 groups based on achievement of Patient Acceptable Symptom State (PASS) postoperatively at minimum 6-month follow-up. The groups were compared based on sex, age, BMI as well as preoperative clinical and radiographic factors, such as injection response, lateral center edge angle (LCEA), alpha-angle, and preoperative patient reported outcomes (PROs). Comparisons were made using Fisher’s exact test and Mann-Whitney U-tests, and variables associated with reaching PASS were determined using multivariable logistic regression. Results A total of 37 patients were included comprised of 30 non-responders that met PASS and 7 that did not achieve PASS (81% rate of achieving PASS). Patients that met PASS had significantly higher average BMI (27.1±5.6 vs 21.5±2.4, p < 0.001) and were less likely to be female (56.7% vs 100%, p = 0.038) compared to patients that did not meet PASS. There were no significant difference in preoperative PROs, radiographic measurements, or injection response % between the two groups. In a multivariable regression model in female patients, only increasing BMI was a significant predictor for reaching PASS (odds ratio 1.8, 95% confidence interval [1.1, 2.9], p=0.025). Conclusion A total of 81% of patients undergoing hip arthroscopy who did not respond to preoperative steroid injection still achieved PASS at minimum 6-month follow-up. All patients who did not achieve PASS were female and BMI was the only other preoperative variable associated with achieving PASS. Further research is necessary to better define which patients may still achieve favorable outcomes after hip arthroscopy despite not responding to preoperative injections.
