The total mean value of patients self-assessment of pain (on a 0–100 visual analogous scale; VAS) statistically significantly decreased from baseline (0), before the first intra-articular HA-injections, until 4 weeks after 5 weekly treatments (****p<0.0001).

7. Fig. 6
The mean joint capsule distension of all joints markedly decreased from baseline (0) until 4 weeks of weekly ultrasound-guided intra-articular HA-therapy (****p<0.0001).

8. Fig. 7
The mean PDUS-score before initiation of HA treatment (0) was statistically significantly higher than that after therapy (****p<0.0001).
