Background. Bone cement spacers are widely used in two-stage revision surgeries for periprosthetic joint infection (PJI) after total knee arthroplasty. Current spacer design results in insufficient release of drugs; therefore, current spacers have low efficacy. In this study, we explored a set of alternative articular spacer using 3D printing technology. This novel spacer will increase effectiveness of revision surgery for PJI. Methods. The spacer was designed using CAD software and constructed on site using 3D-printed silicone mold during debridement surgery. We carried out a retrospective study among patients undergoing treatment using traditional static and new articular spacers. Infection control rate, bone loss, difficulty of revision surgery, knee joint range of motion, function evaluation, and subjective satisfaction of the patients in the two groups were compared. Results. Forty-two patients undergoing knee revision surgery between Jan 2014 and Nov 2019 were included in this study. Twenty-two patients were treated with static antibiotic cement spacers, whereas the other twenty patients were with treated with 3D printing-assisted antibiotic loaded articulating spacers. Patients in the articular group showed significantly lower bone loss on the femur site and tibial site compared with patients in the static group. In addition, patients in the articular group showed significantly less operation time, intraoperative blood loss, and improved knee function and patient overall satisfaction compared with patients in the static group. Conclusions. The 3D printing-assisted articular spacer provides satisfactory range of motion during the interim period, prevents bone loss, facilitates second-stage reimplantation and postoperative rehabilitation, and results in low reinfection and complication rates.

Background. This study evaluates 15 years’ results of the implantation of autoclaved femoral and tibial prosthesis components together with a new same brand polyethylene insert which were used as a temporary articulating spacer in patients with periprosthetic infection of total knee arthroplasty (TKA) in a two-stage reimplantation procedure in 6 patients.  Material and methods. The femoral and tibial prostheses of 6 patients with deep chronic periprosthetic infection of TKA who underwent elective two-stage exchange arthroplasty were autoclaved and reinserted with a new polyethylene insert of the same brand and bone cement mixed with tecoplanin in 2004. Results. Four patients were followed for 15 years. They were all female and between 47-70 years old. The infectious agent was meticillin-resistant Staphylococcus aureus (MRSA) in 3 and coagulase negative Staphy­lococcus in one patient. Patients were invited for second stage reimplantation, but they refused to undergo the second stage. Three of them had their second stage reimplantation after 15, 13 and 10 years while one patient was reinfected after 5 years, in 2009, and arthrodesis was performed. They were all happy with the result and infection free at last follow-up.  Conclusions. 1. Regarding the results of our patients, reinsertion of autoclaved femoral and tibial prostheses together with a new same brand polyethylene insert with teicoplanin loaded bone cement can be used cautiously in the management of periprosthetic deep infection of TKA. 2. That is because patients might not want the second stage reimplantation. 3. We believe that the refusal of patients to undergo the surgery shows that the single-stage treatment is effective.

Introduction. Today, knee arthroplasty is one of the most common surgical procedures. Infection after endoprosthetics is the most dangerous complication in patients who have undergone total knee arthroplasty, which negatively affects the prognosis. Most cases of infection develop within the first 2 years after surgery, and the frequency is 1.5%, and after that it decreases to 0.5%. Material and Method. When a study group of 31 patients (22 female, 9 male) who were diagnosed with infected knee prosthesis and underwent two-stage revision knee prosthesis as a treatment method; the mean age of all patients (31 patients) was 68.78 years. In our study by using the American knee association scoring system; preoperative knee scores of 31 patients who underwent two-stage revision surgery were 35.43 ± 7.14, while this parameter was found to be 83.27 ± 8.89 postoperatively (p <0.01). Conclusion. We believe that two-stage revision surgery is an effective method in the treatment of infection that develops after primary total knee arthroplasty application. Restoration of the joint line in accordance with the anatomical structure will positively affect the clinical results, and the use of a long stem to increase the stability of the prosthesis is appropriate for successful results, especially in the cases with bone defects. Key words: Total Knee Arthroplasty, Two-Stage Revision Surgery, Infected Knee Prosthesis.
