Congenital Fibular Deficiency: Total Knee Arthroplasty with Extraarticular Deformity: A Case Report

JBJS Case Connect. 2021 Apr 2;11(2). doi: 10.2106/JBJS.CC.20.00590.


Case: A total knee arthroplasty (TKA) was performed on a 35-year-old man with congenital fibular deficiency and a 20° varus and 28° antecurvatum tibial deformity of the left lower limb.

Conclusion: One-stage TKA and correction of the extraarticular deformity by means of intraarticular bone resections and a standard soft tissue release were performed to restore the limb's mechanical axis. Patients with congenital fibular deficiency present a wide range of limb deformities because of bone deficiencies or treatment sequels, which might require a specific surgical technique and small-sized implants to obtain good results during a TKA.
