Joint replacement surgery for osteoarthritis is generally considered when the condition reaches a stage where more conservative treatments—such as analgesic medications, physical therapy, weight reduction, or corticosteroid injections—are insufficient to manage the patient's needs.12

Specifically, surgery is utilized to address the following:

Severe Pain and Function: It is employed to relieve severe pain and improve joint function when the disease has caused significant deterioration.1
Progressive Cases: In younger individuals (such as those in their 30s or 40s) who experience a rapidly progressive course of the disease, particularly in the hip, surgical intervention is often required.2
Structural Failure: When the articular cartilage has worn away and the joint's articulation becomes difficult, replacing the diseased tissue with an artificial joint can restore mobility.12

While procedures like osteotomy may be used to redistribute loads in the hip, joint replacement remains a primary strategy for managing advanced, disabling forms of the disorder.12
