Femoral trochlear dysplasia is characterized by abnormal growth and development of the anterior knee joint.1 In this condition the lateral condyle of the distal femur is blunted, resulting in a shallow or absent femoral trochlear groove.2 This blunting is often associated with a small and hypoplastic patella with flattened articular facets.1,2 Trochlear dysplasia often leads to abnormal patellar tracking and can result in subluxation or recurrent dislocations of the patella. Multiple surgical methods of realignment have been described to treat trochlear dysplasia. However, there is scant literature regarding the late complications of untreated dysplasia and its treatment. We present a patient with patellofemoral dysplasia who required a total knee arthroplasty for severe degenerative joint disease.
