  • Title: Outcomes of Arthroscopic Management of Trochanteric Bursitis in Patients With Femoroacetabular Impingement: A Comparison of Two Matched Patient Groups.
    Author: Vap AR, Mitchell JJ, Briggs KK, McNamara SC, Philippon MJ.
    Journal: Arthroscopy; 2018 May; 34(5):1455-1460. PubMed ID: 29395556.
    Abstract:
    PURPOSE: To determine the prevalence of chronic trochanteric bursitis (TB) in patient being treated for femoroacetabular impingement (FAI) and determine the effectiveness of arthroscopic bursectomy and iliotibial band lengthening (AB-ITB-L) at the time of hip arthroscopy for FAI. METHODS: Patients diagnosed with primary FAI and chronic TB were included in the study. Patients were included if they underwent hip arthroscopy with labral repair, femoral and/or acetabular osteoplasty, and AB-ITB-L. Patients were matched by age and gender to patients without chronic TB. RESULTS: The prevalence of chronic TB with FAI was 7% (90/1,278). Females were 5.3 times more likely to have TB compared with males (95% confidence interval: 3.2-8.7). Patients more than 30 years of age were 2.5 times more likely to have TB (95% confidence interval: 1.48-4.4). Of the 90 patients diagnosed with TB, 72 (54 female, 18 male) with an average age of 36.7 years underwent AB-ITB-L at the time of their index hip arthroscopy for FAI. All 72 patients had associated intra-articular pathology consisting of a combined cam and pincer pathology. The TB (average follow-up = 42 ± 9.9 months) and non-TB group (average follow-up = 42 ± 9.1 months) both had significant improvement from preoperative to postoperative scores for Hip Outcome Score Activities Daily Living, Hip Outcome Score Sport, Modified Harris Hip Score, Western Ontario and McMaster Universities Arthritis Index, Short Form (SF)-12 Physical Component score, and SF-12 Mental Component Score. There was no significant difference between the 2 groups in postoperative patient reported outcome scores. CONCLUSIONS: The occurrence of chronic TB in the FAI population, which did not adequately respond to nonoperative management, for a single surgeon high volume hip arthroscopy practice was 7%, and was more commonly seen in women older than 30 years. Patients who undergo concomitant AB-ITB-L for chronic TB report excellent pain relief, and have equivalent results and outcome scores that are not inferior when compared with patients with primary FAI without chronic TB. LEVEL OF EVIDENCE: Level III, retrospective matched case control study.
