Clinical Outcomes After Concomitant Hip Arthroscopy and Iliotibial Band Lengthening With Trochanteric Bursectomy Compared to a Matched Cohort.

PURPOSE

This study sought to determine the clinical outcomes of patients that underwent hip arthroscopy for femoroacetabular impingement (FAI) and concomitant arthroscopic iliotibial (IT) band lengthening with trochan- teric bursectomy (TB group) as well as a matched cohort of patients undergoing hip arthroscopy for isolated FAI symptoms (NTB group) from baseline to a minimum of 2-year follow-up.

METHODS

Patients who were diagnosed with FAI and symptomatic trochanteric bursitis and who failed con- servative measures and underwent hip arthroscopy and arthroscopic IT band lengthening with trochanteric bur- sectomy were identified. These patients were matched by age, sex, and body mass index (BMI) to a group of patients who underwent surgery for FAI without trochanteric bur- sitis symptoms. Patients were separated into two groups: iliotibial band lengthening with trochanteric bursectomy (TB) and non-trochanteric bursectomy (NTB). The patient reported outcomes (PROs) recorded were the modified Har- ris Hip Score (mHHS) and Non-Arthritic Hips Score (NAHS), which were obtained with a minimum of 2-years follow-up.

RESULTS

Each cohort was composed of 22 patients. The TB cohort was composed of 19 females (86%) with a re- ported mean age of 49.3 ± 11.6 years. The NTB cohort was composed of 19 females (86%) with a reported mean age of 49.0 ± 11.7 years. Both cohorts showed significant improve- ment from baseline in the mHHS and NAHS. There was no significant difference in the mHHS and NAHS between the two groups. There was no significant difference between TB and NTB groups with respect to achieving minimal clinically important difference (MCID), [19 (86%) vs. 20 (91%), p > 0.99] or patient acceptable symptom state (PASS), [13 (59%) vs. 14 (64%), p = 0.76].

CONCLUSIONS

There was no difference in PROs of patients with FAI and trochanteric bursitis who underwent hip ar- throscopy with concomitant arthroscopic IT band lengthen- ing with trochanteric bursectomy compared to patients with isolated FAI who underwent hip arthroscopy.
