Total Knee Arthroplasty in Patients with Familial Patellar Absentia Syndrome: A 40-Year Update: A Case Report.
Overview
abstract
CASE: Isolated patella absentia is an extremely rare phenomenon, with only a few published cases and even fewer follow-up reports. Nearly 40 years after the initial presentation of 2 brothers with bilateral congenital absence of the patella and the publication of a case report, we report the clinical and radiographic findings of their subsequent tibiofemoral osteoarthritis, which was treated with bilateral total knee arthroplasty. CONCLUSION: Understanding the biomechanical complications associated with congenital absence of the patella as it relates to a stable knee is vital; in the case of degenerative changes, total knee arthroplasty appears to provide a long-term solution for these patients.
