Figure 1. Association Between Metallopeptidease- 3 (MMP-3) at the Initial Presentation and External Knee Adduction Moment Limb Symmetry Index (KAM-LSI).

Greater plasma MMP-3 concentrations at the initial presentation exam (Y-axis) was associated with lesser KAM (X-axis) at the six-month follow-up exam (r=− 0.64; P= 0.01; partial r=− 0.54; P= 0.03).
