Relatively symmetrical, advanced medial compartment osteoarthritis is seen with significant varus alignment to the knees.
2 case question available
Incidental finding of stress fractures of both medial malleoli was detected. The patient had a history of severe varus osteoarthritis of the knees likely contributing to the mechanical stress on the medial malleoli. There were bilateral symmetrical fracture patterns with no history of trauma.
The patient did not have a known history of osteoporosis but a recommendation for assessment would be advisable. Other potential endocrine anomalies that make contribute to stress/insufficiency fractures should also be assessed for.
