Editorial Commentary : Weighing Complexity Against Anatomy—Preoperative Patellofemoral Parameters Should Drive the Choice Between Ascending and Descending Tibial Tubercle Osteotomy in Medial Open‐Wedge High Tibial Osteotomy

Abstract

Medial open‐wedge high tibial osteotomy is an established treatment for medial compartment osteoarthritis in the varus knee. The conventional ascending tibial tubercle technique can lower patellar height and increase the tibial tuberosity‐trochlear groove distance, raising concerns for secondary patellofemoral disorders. The descending tibial tubercle technique uses a distal cut to preserve the tubercle's relationship to the trochlea and appears to maintain the Caton‐Deschamps index and tibial tuberosity‐trochlear groove. However, this comes at the cost of greater technical complexity and additional fixation requirements. Rather than declaring one approach universally superior, the choice between ascending tibial tubercle‐ and descending tibial tubercle‐open‐wedge high tibial osteotomy should be individualized based on preoperative patellar height and tibial tuberosity‐trochlear groove distance. The added complexity of the descending technique is best reserved for patients in whom the ascending approach would create aberrant patellofemoral anatomy.
