Abstract
We reported four cases of infection after total knee arthroplasty (TKA) which required the removal of implants. Three cases were osteoarthritis and one was rheumatoid arthritis. Two cases were staphyloccocus aureus, one case was staphyloccocus epidermidis and one case was MRSA on culture of joint fluid. The therapy after removal of implants was a primary revision TKA, a secondary revision TKA and two arthrodesis with insertion of cement beads containing antibiotics or continuous irrigation.
In all cases the infection was controlled. Revision TKAs had good fixation without loosening and sinking. Complete fusions were obtained by arthrodesis.
We recommended that in treat infected TKA the degree of infection, variety of the bacteria and complication had to be investigated sufficiently and planned the therapy after removal of implants.
