Joint surgery is a medical procedure aimed at repairing or replacing damaged joints, which can result from conditions like arthritis, injury, or wear and tear. Common types of joint surgery include knee replacement, hip replacement, and shoulder surgery. These procedures can help relieve pain, improve mobility, and enhance the overall quality of life for patients. During joint surgery, a surgeon may remove damaged tissue, realign bones, or implant artificial joints made of materials like metal or plastic. Recovery times vary depending on the type of surgery and the patient's health, but rehabilitation often includes physical therapy to restore strength and function to the joint.
