Study Arms:
- BJI group (Type: None): Patients with an BJI on material (prosthesis or other implant) infected by Staphylococcus aureus\* Patients are follow-up during two years after surgery.~\*Diagnosis of staphylococcus aureus monoinfection realized a posteriori after surgery on bacteriological sample
- Control Group With material (Type: None): Patients with mechanical problems on implanted equipment (control cohort), without infection\* Patient of this group are follow-up until surgery.~\*Diagnosis of staphylococcus aureus monoinfection realized a posteriori after surgery on bacteriological sample
- Group osteomyelitis (Type: None): Patients with chronic osteomyelitis\* Patient of this group are follow-up until surgery.~\*Diagnosis of staphylococcus aureus monoinfection realized a posteriori after surgery on bacteriological sample
- Control Group with cruciate ligament surgery (Type: None): Patients having cruciate ligament surgery Patient of this group are follow-up until surgery.

Based on this trial design, predict the completion outcome and termination type (if applicable).
