Comparison of Clinical and Biomechanical Outcomes between Partial Fibulectomy and Drug Conservative Treatment for Medial Knee Osteoarthritis

Figure 4

Changing trend of lower limb alignment and 3D gait outcomes before upper partial fibulectomy and during the 1-year follow-up. (a) Gait speed. (b) Cadence. (c) Walking flexion/extension ROM. (d) Overall peak KAM. (e) HKA angle. Blue denotes a significant difference compared with the preoperative value in the drug group ( denotes ; denotes ). Red denotes a significant difference compared with the preoperative value in the fibulectomy group ( denotes ; denotes ). ROM: range of motion; KAM: knee adduction moment; HKA angle: hip-knee-ankle angle.
