Patient characteristics cannot predict the long-term effect of an intra-articular bupivacaine and corticosteroid injection in patients with femoroacetabular impingement: A retrospective cohort study

BackgroundTo evaluate predictors for effect of an intra-articular (IA) bupivacaine and corticosteroid injection in patients with femoroacetabular impingement syndrome (FAIS).MethodsAll between 18 50 years old FAIS who received 2016 2019 were eligible this retrospective study. Two groups made, the non-arthroscopy group (patients whom conservative treatment physiotherapy IA was sufficient) arthroscopy needed because failed). Multiple regression analysis performed to analyse predict arthroscopic intervention based on sex, age, body mass index, duration complaints, alpha angle abnormal bone morphology.ResultsIn total 103 included; 46 57 group. The had similar baseline characteristics. A 37 (36%) 3 months or longer from injection; 31 (54%) versus 6 (13%) (P < 0.001). Male sex seems have negative influence injection. None variables could significantly if a patient would undergo (F(7,103) = 8.54, p 0.3, R2 0.11). not be predicted (p 0.1; 0.13).ConclusionThere are no characteristics that benefit need within 1 year after Only male
