The aim of the study was to assess the effectiveness of an ultrasound guided intra-articular hip injection of a single dose of high-weight hyaluronic acid (HA) combined with complex balneal and kinetic therapy in the treatment of hip osteoarthritis.
This was a single site, prospective, open-label, investigator-initiated study. Sixty patients were enrolled and received complex balneal and physical kinetic treatment during 12 days, combined with one intra-articular ultrasound guided injection, at the end of treatment.
The study was conducted between June 2016 and December 2017 in Balneal and Rehabilitation Sanatorium Techirghiol. Clinical evaluations were performed at baseline using VAS scale and Harris Hip Score(HHS). After one month and 6 months patients were called and asked about the symptoms. One year after the injection, the patients returned to the clinic to perform a follow-up and final visit through the VAS scale and Harris Hip Score (HHS).
The mean values of VAS recorded at baseline was 6.79, (2.15 std.dev).The mean values of VAS recorded one month after treatment was 2.10, (1.88 std.dev). The mean values of VAS recorded six month after treatment was 1.51,(1.98 std.dev).The values of Harris Score 1 were between 20 și 91, with mean values 62.72 and standard deviation 16.22. No adverse effects were registered.
