*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.
