The most common injury to the lateral femoral condyle is an osteochondral fracture combined with a patellar dislocation.
Typically, the condyle will fracture (and the patella may dislocate) as a result of severe impaction from activities such as downhill skiing and parachuting.
[1] Open reduction and internal fixation surgery is typically used to repair an osteochondral fracture.
For a AO Type B1[2][circular reference] partial articular fracture of the lateral condyle, interfragmentary lag screws are used to secure the bone back together.
