Management of Lateral Femoral Condyle Non-union with Autogenous Bone Graft in CAS Total Knee Arthroplasty.

Introduction: Neglected distal femur fractures often present with significant uncontained bone defects of the lateral femoral condyle (LFC) leading to a valgus deformity and lateral compartment arthritis.

Case Report: Bone defect can be managed with the help of autogenous bone graft harvested from a distal femur cut and shaped in the form of an augment. The objective of using bone graft along with the primary femur was to restore bone stock in a young patient and prevent the use of an augment with a revision femur and intramedullary rod.

Conclusion: The use of computer navigation helped in getting accurate components and overall alignment thus facilitating compression at the bone graft site and early union.
