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.
