A 78-year-old referred to CRIOAc Lyon for recurrent prosthetic joint-infection of the left knee, associated with extensor mechanism disruption and exposure of the prosthetic joint
Exposed prosthetic joint and extensor mechanism disruption due to infection
Functional outcome 6 years after multiple acts of surgery to manage infection and after the placement of a silver knee arthrodesis prosthesis.
A 64-year-old patient, presenting with chronic osteomyelitis caused by P. aeruginosa following a road accident in 1984, was treated by curettage and gentamicin bone substitute

After 2 years, favourable outcome and pain-free walking without local signs of infection
A 48-year-old patient referred to CRIOAc Lyon for a spacer infection, an indirect consequence of a gunshot wound (a spacer is a bone cement used to manage bone loss)
The patient could no longer walk. Due to the destruction of the distal femur by the impact of the bullet, the patient had to undergo bone resection with the implantation of a spacer.

CT scan of patient’s knee affected by spacer infection
Favourable outcome after multiple acts of surgery in response to infection, and after placement of a knee prosthesis.
Two years after, functional outcome can be observed. The patient no longer presents infection and can walk painlessly.
A 71-year-old patient, having presented with a chronic Propionibacterium acnes prosthetic joint-infection of the left hip, required complex implant removal
This patient underwent resection-arthroplasty and was able to walk again without a new prosthesis.

Postoperative x-ray of pelvis
Two years later, functional outcome can be observed. The patient no longer presents infection and can walk painlessly, despite missing hip prosthesis.
