The pathogenesis and treatment of anterolateral rotatory instability

This is a report of a surgical technique to secure improved posterior restraining power and to tighten the fibular collateral ligament to a greater degree than the iliotibial band transfer alone. The early results from this lateral repair are superior to those previously reported utilizing the iliotibial band transfer alone. This corroborates Kennedy's observation that the iliotibial band transfer alone may not possess adequate strength for severe forms of lateral tibial plateau subluxation. Reinsertion of the biceps as described above appears to provide requisite additional strength without jeopardizing the iliotibial tract.
