What is the primary purpose of joint replacement surgery?

The primary purpose of joint replacement surgery is to relieve pain and restore joint function. This type of surgery is typically performed when a joint has been severely damaged or worn out due to conditions such as osteoarthritis, rheumatoid arthritis, or injury. The procedure involves removing the damaged joint surfaces and replacing them with artificial components, thereby reducing pain associated with movement and significantly improving the patient's ability to perform daily activities.

While physical therapy can aid in improving mobility post-surgery, it is a supportive measure following the operation, not the primary purpose of joint replacement itself. Diagnosing joint diseases typically involves imaging studies or other diagnostic tests, not surgical intervention. Additionally, while strengthening surrounding muscles may be an important aspect of rehabilitation after surgery, it is not the main goal of joint replacement. The focus of the surgery is on alleviating pain and restoring normal joint function, allowing patients to return to their desired activities and enhance their quality of life.
