Recent advances

Large size heads-advantage of large size heads is that the incidence of dislocation is lower and one can squat and sit cross-legged

Alternative bearing surfaces-traditionally the femoral head was metal and the cup was polyethylene, newer technology offers option of ceramic on poly and ceramic on ceramic bearing surfaces this reduces wear and theoretically suppose to increase the life of the artificial joint
