“…Fusions are performed using external fixators [11,22,53], intramedullary nailing [2,3,13,14,28,42,54], or plate and screw fixation [35]. Patients with knee fusions are able to perform strenuous physical tasks, but the loss of motion at the knee makes sitting difficult [25].…”

Background Treatment of chronic periprosthetic joint infections (PJIs) after TKA is limited to fusions, above-theknee amputations (AKAs), revision TKA, and antibiotic suppression and is often based on the patient's medical condition. However, when both fusion and AKA are options, it is important to compare these two procedures with regard to function. Questions/purposes Do patients receiving a knee fusion for PJI after TKA have better function compared to patients receiving an AKA?Methods We retrospectively reviewed patients who were eligible for either fusion or AKA after PJI TKA. Thirtyseven patients underwent a fusion for PJIs after TKA between 1999 and 2010. Nine patients died postoperatively and eight patients were lost to followup, leaving 20 patients. Patients completed a specialized questionnaire about their fusion, and functional capability was assessed by the SF-12. We compared fusions to a previously published group of six patients who underwent AKA for recurrent PJI after TKA.

“…It is unclear whether there is a significant difference in fusion rates between one- or two-stage external fixator because of the variability of selection criteria for knee arthrodesis between studies 23. Some authors suggest that staged external fixator should always be used in an attempt to eradicate multimicrobial or virulent infection where there is extensive bone loss 23. We are also a strong believer of two staged technique especially in patients with moderate to severe bone stock deficiency and 4B type of hosts according to Cierney-Mader classification.…”

Background:Knee arthrodesis may be the only option of treatment in cases of chronic infected total knee arthroplasty (TKA) with concomitant irreparable extensor mechanism disruption, extensive bone loss or severe systemic morbidities. Circular external fixation offers possible progressive adjustment to stimulate the bony fusion and to make corrections in alignment. We evaluated the results of knee arthrodesis with one or two stage circular external fixator for infected TKA.Materials and Methods:16 cases of femoro-tibial fusion were retrospectively evaluated. Male-to-female ratio was 10:6. Mean age of the patients was 62.2 years. Cierney-Mader classification was used for anatomical and physiological evaluation while the bone stock deficiency was classified into mild, moderate and severe. Surgical technique involved either single or two stage arthrodesis using circular external fixator.Results:Union was achieved in 15 patients (93.75%). The mean duration for union (frame application time) in these patients was 28.33 weeks (range 22 to 36 weeks). Analysis showed that in the group with frame application time of less than 28 weeks, the incidence of mild to moderate bone deficiency was 83.33%, while in the frame application time more than 28 weeks group the incidence was 20% (P-value 0.034). Similarly the incidence of Cierney-Mader 4B (Bl, Bs, Bls) was found to be 33.33% in the group of frame application time of less than 28 weeks, while it was 90% in the group with frame application time more than 28 weeks (P-value 0.035).Conclusion:Circular external fixator is a safe and reliable method to achieve knee arthrodesis in cases of deep infection following TKA. Severe bone stock deficiency and Cierney- Mader type B host are likely risk factors for prolonged frame application time. We recommend a two-stage procedure especially when there is compromised host or severe bone loss.

We retrospectively evaluated eight patients who underwent arthrodesis of the knee using cannulated screws. There were six women and two men, with a mean age of 53 years. The indications for arthrodesis were failed total knee arthroplasty, septic arthritis, tuberculosis, and recurrent persistent infection. Solid union was achieved in all patients at a mean of 6.1 months. One patient required autogenous bone graft for delayed union. One suffered skin necrosis which was treated with skin grafting. The mean limb-length discrepancy was 3.1 cm. On a visual analogue scale, the mean pain score improved from 7.9 to 3.3. According to the Knee Injury and Osteoarthritis Outcome score quality of life items, the mean score improved from 38.3 pre-operatively to 76.6 at follow-up. Cannulated screws provide a high rate of union in arthrodesis of the knee with minimal complications, patient convenience, and a simple surgical technique.
