The Lindemann operation, originally performed in 1950 as a
reconstructive procedure for the anterior cruciate ligament, was performed
in the knees of eight patients suffering from rotatory instability.
Although the instability persisted, as shown by roentgenographic and
clinical examination, treatment with the tendon transfer appears to have
provided dynamic stabilization. Seven of the eight patients so treated were
subjectively improved, and they returned to sports or activities which they
had not been able to perform prior to surgery.
