It depends on your age and activity level. The best reports on standard metal plastic hip replacement indicate that in patients with average age 70 , 95% last 10-15 years. With these same implants , patients age 40-60 , the implants survivorship drops to 70-80% over 8 years. Metal hip surface replacement shows 96% survivorship at 7 years in patients age 40-60. Studies of ceramic-ceramic , metal crosslinked polyethylene and small bearing total hip replacements show approximately 95-98% survivorship in young patients as well.
