Evaluation of Posteriorization Following Pure Distalization Tibial Tubercle Osteotomy

Contemporary TTO-d resulted in the successful correction of patella alta without appreciable posteriorization of the tibial tubercle. These results support the positive clinical outcomes seen with TTO-d, including for chondral lesions, and may reduce concerns about inadvertent posteriorization when performing this procedure. While overdistalization with the formation of patella baja can increase patellofemoral contact pressure beyond native ranges, the current results suggest that restoration of a normal patellar height is unlikely to do so.
