Clinical particulars

35-year-old male presented with recurrent periprosthetic infection after complex hinged total knee replacement (TKR), performed 1 year ago, to treat severe post-traumatic knee osteoarthritis. 6 months after the initial procedure, he developed periprosthetic infection.

Change of polyethylene, synovectomy, microorganism specific systemic antibiotics and repetitive arthroscopic lavage of the knee failed to control the infection.

Because of the knee stiffness and the compromised soft tissue condition, a revision TKR was not deemed appropriate so decision was made to treat infection with knee fusion.

Outcome

7 months post-operatively, the infection remained controlled, the bone had consolidated and the patient had returned to daily activities without significant restrictions or symptoms.

2 years post-operatively, no recurrence of infection had occurred.

The mixing of antibiotics with the STIMULAN Kit / STIMULAN Rapid Cure device is considered off-label usage of the medicinal product. To do so is at the professional risk of the surgeon / healthcare professional.
