The Early Arthritic Lateral Compartment: Can Osteotomy Really Restore My Patient's Function?

Video Transcription

Video Summary

This presentation discusses distal femoral osteotomy (DFO) for lateral compartment osteoarthritis due to distal femur malalignment. DFO can effectively offload lateral compartment forces when the mechanical axis passes through the lateral compartment and distal femoral deformity is present. However, it's contraindicated if malalignment is absent, if deformity lies elsewhere (e.g., proximal tibia), or if rotational deformity exists. Overcorrection risks joint line obliquity and increased shear forces. Proper patient selection and angle measurement are crucial. Medial and lateral surgical approaches have pros and cons, with no clear difference in outcomes. DFO can complement meniscal or osteochondral treatments for lateral compartment pathology.
