The result of the knee arthroplasty after septic arthritis using the technique of bilocal compression-distraction osteosynthesis according to Ilizarov and osteoplasty with the patella(A case report)
The work deals with a clinical example of treating a female patient with periprosthetic infection in the knee area. The following surgical intervention performed: removal of the left knee implant, necrectomy of the knee bones by resection type (7 cm), draining. Osteosynthesis of the femur and the leg using the Ilizarov device carried out. The characteristic feature of the performed surgery consisted in making resection within normal bone, as well as forming the femur and leg bones of “fossa-sphere” type (a hollow formed in the femoral condyles, and the tibial end fitted to the congruence with the hemisphere). A second course of antibiotic therapy used postoperatively. Wound healing occurred by first intention, fistulas closed. The following delayed surgery performed 1.5 months after the purulent process was stopped in the knee: osteotomy of the left tibia in its lower third in order to fill the defect. The technique of bilocal compression-distraction osteosynthesis in the left femur and leg implemented for 127 days. Fixation with the Ilizarov device lasted for 174 days. A positive result achieved.
