Total Hip Arthroplasty Using the McKee & Watson-Farrar Prosthesis:A Prospective Follow-up Study of 327 Arthroplasties

Metal-on-Metal Total Hip Joint Replacement: A Minimum Follow-Up of Five Years

“…The McKee-Farrar (33) metal-on-metal prosthesis had led to early failures due to design deficiencies. Short to medium-term results with the use of this pros- thesis showed a rate of loosening from 7.4% to 16% (25,26). A high long-term failure rate was noted by August et al (34) who showed a survivorship of 50% at 18.7 years and 27.5% at 20 years.…”

“…Initially, metal-on-metal articulations were investigated simultaneously with the metal-on-polyethylene by McKee and Watson-Farrar (23) but were discarded because of poor results: loosening of the acetabular socket due to design deficiencies and infection (24)(25)(26). Weber et al (27) reintroduced the concept of metal-on-metal articulation by developing Metasul ® articulation in 1988 (Sulzer, Winterthur, Metal-on-metal total hip joint replacement: a minimum follow-up of five years Switzerland).…”

Acetabular Cups in 60 mm Metal-on-Metal Bearings Subjected to Dynamic Edge-Loading with 70° Peak-Inclination in 10-Million Cycle Simulator Study

“…Pioneering THA designs of the 1960-1970 era incorporated metal-on-polyethylene (MPE) and metal-on-metal (MOM) bearings, the latter using mainly cobalt-chrome alloys (as-cast CoCr). History shows that the 1st generation MOM bearings encountered many failures, considered multifactorial due to limited knowledge in design, instrumentation, and bone-fixation concepts [1][2][3][4][5][6]. In some cases, adverse CoCr wear produced severe biological reactions around the hip joints [3,7].…”
