Modifications of the Fulkerson osteotomy: a pilot study assessment of a novel technique of dynamic intraoperative determination of the adequacy of tubercle transfer.

Medial transfer of the tibial tubercle is commonly implemented to correct patellar alignment in patients with patellar instability. However, the extent of transfer needed is difficult to determine. This article reports a pilot-study experience with a novel technique employing intraoperative femoral nerve stimulation to better determine the distance of tubercle transfer required for proper patellar tracking.
