摘　　要：The gonarthrosis with congenital dislocation of the patella is rare condition. This paper will report about total knee arthroplasty (TKA) for the valgus knee with bilateral congenital dislocation of the patella. A 52-year-old woman presented to our hospital with progressive pain in bilateral knees. Both knee showed severe valgus deformity and lateral dislocation of the patella. Anteroposterior weight-bearing radiographs showed osteoarthritic changes in the lateral compartment with 7 valgus deformity at the right and 15 at the left. A bilateral TKA with cruciate retained components (NAKASHIMA FINE) was performed. Good tracking of the patella was achieved by using a lateral parapatellar approach and vastus medialis plication. There are no normative guidelines of operative procedure about TKA for osteoarthritis of valgus knee with congenital dislocation of the patella. With some referencing to current literature, strategies to good patella tracking are discussed.The gonarthrosis with congenital dislocation of the patella is rare condition.
