ABSTRACT: 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.
