Total hip and knee replacement are surgical procedures that are performed to replace damaged hip or knee joints with artificial prosthetic joints. These procedures are typically recommended for individuals who have severe joint pain, stiffness, and decreased mobility due to osteoarthritis, rheumatoid arthritis, or other joint conditions. Both total hip and knee replacement surgeries are major procedures and require a significant amount of recovery time. Patients are typically required to undergo physical therapy and rehabilitation to regain strength, flexibility, and range of motion. Pain management, blood clot prevention, and infection prevention are also important parts of the recovery process. Patients may need to use assistive devices such as crutches or walkers for a period of time after surgery.
