Platelet Rich Plasma and Hyaluronic Acid Blend for the Treatment of Osteoarthritis: Rheological and Biological Evaluation - Fig 1

(A) Viscosity curves of the pure viscosupplements. The graph represents the viscosity as a function of the shear rate. For all specimens the typical shear-thinning behavior of HA is observed. SN displays viscosity one order of magnitude lower than the other specimens. (B) Mechanical spectra of the pure viscosupplements. The graph represents the shear storage modulus G' (triangles) and the shear loss modulus G" (circle) as a function of the angular frequency.
