Patient was debrided 3 times. 22 cultures were colected intra-operative, all negative, without use of antibiotics. CRP, ESR and blood count were normal (collected 5 times). The knee is without signs of inflammation. Incisions are healed, but with continuos joint effusion. X-ray shows well cemented and positioned scorpio knee arthroplasty.
