The goal of this clinical trial is to learn if vitamin D supplementation affects postoperative rehabilitation in osteoarthritis patients who underwent joint arthroplasty. The main questions it aims to answer are:
Does oral vitamin D supplementation for a period of time after joint arthroplasty affect the postoperative recovery speed in patients who have vitamin D deficiency? Does oral vitamin D supplementation after joint arthroplasty affect the long-term recovery of joint functions in patients who have vitamin D deficiency?
Participants will:
Take vitamin D oral supplement every day for 3 months. Visit the clinic in 1, 3, 6, 12 months after joint replacement surgery for checkups and tests.
Vitamin D deficiency (blood 25-hydroxyvitamin D value < 20ng/ml);
Meeting the diagnostic criteria for hip or knee osteoarthritis;
Planning to undergo hip or knee arthroplasty after clinical assessment;

Knee joint function
Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC). Pain ranging from 0 to 20 points; stiffness, 0 to 8 points; and physical function, 0 to 68 points. Higher scores represent worse pain, stiffness, and functional limitations.
Hip joint function
Harris Hip Score. The maximum score possible is 100. Results can be interpreted with the following: \<70 = poor result; 70-80 = fair, 80-90 = good, and 90-100 = excellent.
Muscle strength
