Abstract:
Objective To report our early experience for treatment of infected total knee arthroplasty (TKA) using antibiotic-loaded articulating cement spacer. Methods From June 2004 to April 2005, 5 patients with periprosthetic knee infection were treated with 2-stage reimplantation protocol. The study group included 1 male and 4 females, with average age of 67 years(range, 57-75 years). The initial procedure consisted of thorough debridement, removal of prosthesis and implantation of antibiotic-loaded articulating cement spacer. The postoperative course consisted of graduated knee motion and partial weight-bearing activity. Each patient received a 6-week course of organism-sensitive antibiotic therapy. The high restricted total knee prosthesis was reimplanted after infection controlled. Results 3 patients had a basic diagnosis of rheumatoid arthritis and two of them took steroid for a long time. The other two patients suffered from osteoarthritis before primary TKA were both with diabetes. Sinuses were emerged in all of 5 patients and blockage phenomenon was found in two of them. There were no cases of fracture, dislocation, or instability associated with articulating cement spacer. The average time between the two stages was 15 weeks. All 5 patients were able to ambulate with assistance and flex the knee without difficulty in the interval before reimplantation. The average knee flexion was 95? and the average knee society score(KSS) was 81 points. A mean ten months follow-up was evaluated after reimplantation. There were no recurrence, or new infections after reimplantation. Conclusion Infection after a TKA can be successfully managed with an antibiotic-loaded articulating cement spacer and knee motion can be preserved in the interval prior to implantation. The end result is effective treatment of infection and facilitation of reimplantation.
