a. Pre-operative radiograph of a patient with multiple bilateral patellar subluxations and recurrent right patellar dislocations interfering with participation in competitive basketball. Anatomic lateral distal femoral angles (aLDFA) indicate bilateral excessive genu valgum. Bilateral medial distal femoral hemiepiphyseodesis was performed with plate-screw constructs. b. At the time of hardware removal, both knees were symptom-free and the patient had returned to competitive basketball. The aLDFA corrected to normal bilaterally. c. At near 30 months post-op, the patient remained symptom-free in the left knee and had experienced only 1 recurrent dislocation of the right patella, even with full participation in competitive basketball. The aLDFA rebounded since the time of hardware removal, but remains normal bilaterally.
