Early complications: dislocation, infection, nerve injury, DVT/PE. Late complications: aseptic loosening, periprosthetic fracture, heterotopic ossification, osteolysis, implant wear. Dislocation risk factors: posterior approach, malposition, neuromuscular disorders. Nerve injuries: sciatic > femoral; incidence ~1%. Infection: incidence 0.5–2%; requires DAIR or revision.
