Unconstrained total knee arthroplasty in significant valgus deformity: a modified surgical technique to balance the knee and avoid instability

Purpose Correction of valgus deformity in total knee arthroplasty (TKA) is technically challenging and has produced variable results. A modified surgical technique involving adapting the distal femoral cut with minimal soft tissue release is proposed. The authors hypothesise that using this technique would result in satisfactory radiological and functional outcome.
