Objectives

The approach in total knee arthroplasty (TKA) with severe valgus deformity is controversial. The lateral parapatellar approach has been proposed for several years, but surgical technique of this approach was unusual and difficult. Therefore, we have consistently been selected medial parapatellar approach (MPP) for all cases. In this study, we investigated the short term results of TKA for severe valgus deformity with MPP about clinical and radiographic assessment.

Methods

Seven knees in seven cases of severe valgus knees with stand femorotibial angle (FTA) less than 160 degrees were enrolled. Osteoarthritis were 6 cases, hemophilic arthropathy was 1 case and no rheumatoid arthritis case. There were 6 female and 1 male, and mean age was 63.6 years (41–75 years). Duration of follow up ranged 3 months to 22.5 months, with mean of 10.9 months. We compared alignment on standing radiograph, range of motion (ROM), the Japanese Orthopaedic Association (the JOA) score for osteoarthritic knee pre/postoperatively, and examined post operative complication retrospectively.
