**2. Definition**

Arthroplasty is an orthopedic surgical procedure, where the articular surfaces of a synovial joint are removed, remodeled, or replaced, to restore function and relief pain. It is indicated in cases of advanced joint destruction caused by different etiologies (osteoarthritis, inflammatory arthritis, trauma, tumors, sequelae of osteoarticular infections, neurological injuries, among others), where three factors combine: severe and refractory pain, functional limitation, and poor quality of life.
