Use of viscosupplementation for the recovery of active football players complaining of knee pain

Figures & data

Figure 1 Pain VAS, PGA, and Lequesne index scores at baseline, 1 week after the first injection, and at 4, 12, and 24 weeks after the first injection.

Note: All parameters observed were found to be statistically significant when matched with baseline already after 1 week, and the statistical significance was maintained until the end of follow-up (P<0.05 for all parameters).
Abbreviations: PGA, patient’s global assessment; VAS, visual analog scale.

Figure 2 Pain VAS score measured on the day of injections (t0) and at 1 (t1) and 2 (t2) days after each injection.

Abbreviations: VAS, visual analog scale; d, days.
