Joint replacement systems are medical devices designed to replace damaged or worn-out joints in the body, commonly in the knees, hips, and shoulders. These systems typically consist of artificial components made from materials like metal, plastic, or ceramic, which mimic the function of natural joints. The goal is to relieve pain, restore mobility, and improve the quality of life for patients suffering from conditions such as arthritis or joint injuries. The procedure for joint replacement involves surgically removing the damaged joint and inserting the replacement components. Rehabilitation and physical therapy are often necessary afterward to help patients regain strength and movement. Advances in technology have led to more effective and durable joint replacement systems, enhancing patient outcomes and satisfaction.
