Abstract:
Approximately 2, 000 patients in Sweden currently require active follow-up due to metal-on-metal (MoM) hip implants. These patients are at risk of complications such as elevated metal ion levels and adverse local tissue reactions (e g pseudotumors) (Fig 1). Identified risk factors include female sex, suboptimal implant selection, and, in resurfacing arthroplasties, the use of smaller femoral heads (.
