We evaluated and compared the effectiveness of intra-articular injection of hip
joint using hyaluronic acid and steroid in patients with femoroacetabular
impingement (FAI). Thirty patients with FAI clinically and radiologically were
enrolled and underwent hip injection using steroid (TA) or hyaluronic acid (HA)
at 0-weeks with cross-over injection at 2-weeks in patients without clinical
response of decrease of pain intensity less than 2-point. Patients were followed
up to 12-weeks for pain intensity (Numeric rating scale, NRS: 0-10), hip
disability score (HOOS), oral medication and adverse events. In 17 patients
without cross-over, HOOS at 2-weeks was improved significantly in patients with
HA injection (mean increase of HOOS = 13.8 with HA vs. -2.2 with TA, P = 0.031)
without difference of NRS (P = 0.943). In 13 patients with cross-over, NRS was
significantly improved at 2-weeks with first TA injection (mean decrease of NRS=
1.7 with first TA vs. 0.3 with first HA, P = 0.036), without difference of HOOS
(P = 0.431). At 4-weeks, NRS and HOOS were significantly different according to
injection drugs (NRS: 0.9 with TA first and HA later vs. 2.7 with HA first and TA
later, P = 0.001; mean increase of HOOS: 5.3 with TA first and HA later vs. 10.2
with HA first and TA later, P = 0.032). Intra-articular hip injection may be
effective in FAI, with faster effect of pain improvement by TA and more delayed
effect of function improvement by HA.
