Abstract
Objective
To assess if ultrasound (US)-guided viscosupplementation can reduce pain and improve function in elderly patients with cuff tear arthropathy.
Patients and methods
Ninety-three patients aged over 65 with grade 3 or above cuff tear arthropathy were included in this prospective open-label non-randomized trial. Institutional review board approval and informed consent were obtained. Thirty-three patients received intra-articular injections of sodium hyaluronate under US guidance. Sixty patients constituted the control group. Shoulder joint function was assessed with Constant scores (CS) and pain with a visual analogue scale (VAS).
Results
Compared with controls, treated patients reported a significant decrease in symptoms at 1 (mean CS 66 ± 3.1 vs 37 ± 6.9; mean VAS 1.9 ± 1.2 vs 6.9 ± 2.2), 2 (mean CS 65 ± 3.2 vs 35 ± 7.2; mean VAS 1.7 ± 1.2 vs 6.8 ± 2.5), 3 (mean CS 66 ± 3.4 vs 33 6.1; mean VAS 2.3 ± 1.2 vs 6.6 ± 1.9), and 4 (mean CS 62 ± 3.0 vs 34 ± 6.5; mean VAS 3.3 ± 1.4 vs 7.8 ± 3.1) months, p < 0.001. After 5 months there were no differences.
Conclusion
US-guided viscosupplementation is a beneficial therapeutic option in the first months of treatment
