  1. *Values are mean ± SD; † P < 0.05; §Elementary or less.
  2. WOMAC scores: pain 0–20, function 0–68, stiffness 0–8; higher scores indicate greater difficulty.
  3. KSS: Knee score 100–0, Functional score 100–0, higher scores indicate better health state.
  4. CES-D10 scores: > 10 indicate depression; Pain VAS: 0–10, better to worse.
