Abstract

Introduction

Patients with patellofemoral instability with trochlear dysplasia may be treated with trochlear osteotomy.

Case presentation

We present a patient with patellofemoral instability treated with trochlear osteotomy. The procedure resulted in nonunion with painful bony impingement and isolated patellofemoral osteoarthritis. Patellofemoral arthroplasty was performed.

Conclusion

Patellofemoral arthroplasty may be considered a salvage procedure for failed surgical treatment for trochlear dysplasia.
