Majority of prior operations were core decompression procedures for avascular necrosis.
Failure rates for reasons other than metallosis are listed for the current study. Post: posterior approach, AL: anterolateral approach, DL: direct lateral approach. COC: ceramic on ceramic, MOXLP: metal on highly cross-linked polyethylene, MOP: metal on polyethylene, MOEP: metal on E-polyethylene, COXLP: ceramic on highly cross-linked polyethylene, MOM: metal on metal.
