Hip

A popular bearing surface from the 1990s to the mid-2000s, published literature estimated more than 1 million metal-on-metal total hip arthroplasties were performed since the design’s introduction, with 80% remaining in situ. However, metal-on-metal hip implant use decreased 10 years after its peak due to revisions related to adverse reaction to metal debris, infection and aseptic loosening.

For high-level athletes with bilateral femoroacetabular impingement and labral tears, staged bilateral hip arthroscopy performed 4 to six weeks apart is a safe and effective treatment option, according to a study by researchers in the department of orthopedics at Mayo Clinic Arizona.
