  1. *P < 0.05 versus Lumbar group, #P < 0.05 versus Hip group, §P < 0.05 versus Knee group, P < 0.05 versus Foot & Ankle group,
  2. GLFD-25 25-Question Geriatric Locomotive Function Scale; LS locomotive syndrome; SD standard deviation
  3. A GLFS-25 score of ≥16 and ≥ 7 were classified as LS stages 2 and 1, respectively
  4. LS improvement was defined as the postoperative downgrade of LS grade in each of the tests
  5. When the preoperative LS grade was zero in the rare cases, the improvement was defined as the postoperative improved measurements of the tests
