Total knee arthroplasty has been performed even for severe valgus knee. All ligaments around knee must be balanced to obtain good clinical results. Especially medial collateral ligament plays a role as a stabilizer. For severe valgus knee, however, deep medial collateral ligament (dMCL) located closely to the articulating tibial surface [Fig. 1] can be damaged by bone resection in standard tibial osteotomy which may leads to progress valgus deformity. There are no report of dMCL preserved total knee arthroplasty for sever valgus knee. Thus it was evaluated the clinical outcomes of total knee arthroplasty for severe valgus knees using dMCL preservation technique.Background
