Re-revision surgery for re-recurrent valgus deformity after revision total knee arthroplasty in a patient with a severe valgus deformity: A case report
cqvip:BACKGROUND A recurrent valgus deformity was a common complication after total knee arthroplasty(TKA)in patients with valgus deformity.However,re-revision surgery for re-recurrent valgus deformity after revision TKA in patients with valgus deformity before primary TKA was uncommon.CASE SUMMARY We reported a 72-year-old female patient with two recurrent valgus deformities after TKA for a valgus knee deformity who underwent two revision surgeries to rectify the deformity.In the re-revision surgery,bone defects were successfully reconstructed by the augments and cement in combination with screws and a sleeve.An appropriate neutral alignment of the lower limb was restored by the perfect femoral entry point and the long diaphyseal cementless stem.Adequate fixation of the metaphysis and diaphysis of the femur was obtained by the sleeve and long diaphyseal cementless stem.The patient was pain-free and deformityfree for 2.5 years.CONCLUSION The management of bone defects,the choice of the stem and the femoral entry point were of vital importance in the revision or re-revision TKA for a recurrent valgus deformity.
