What are the current scientific principles guiding selection of materials, devices, and procedures for total hip joint replacement?
Most THR’s are performed on patients with arthritis of the hip. Before considering such patients for THR, a comprehensive medical program should be undertaken. Current therapeutic modalities for hip arthritis should consist of a carefully coordinated, multidisciplinary effort. Factors affecting therapeutic decisions include precise diagnosis, stage and extent of arthritis, pathogenesis of symptoms (inflammatory or mechanically induced), and the age and expectations of the patient. Short- and long-term goals include relief of pain and stiffness and restoration (or maintenance) of function. General therapeutic approaches to arthritis of the hip include patient and family education, proper rest and protective devices (canes, crutches, walkers), elimination of suspected aggravating factors (obesity, over-exercise), utilization of accepted physical therapy programs designed to relieve pain, maintenance and restoration of joint motion and muscle strength, and advice to patients regarding aid
