A Modified Osteotomy for Anteromedialization of the Tibial Tubercle
نویسندگان
چکیده
Tibial tubercle osteotomy is a common treatment option for a number of patellofemoral joint disorders including chondromalacia, "anterior knee pain" syndromes, patellofemoral arthritis, and patellar instability. Tibial tubercle osteotomy can modify tracking and/or patellofemoral contact forces to effect the unloading of chondral defects of the patella or trochlea, correct multiplanar suboptimal alignment, and be used in conjunction with soft-tissue stabilization procedures for instability. The purpose of this Technical Note is to describe, in detail, a modified osteotomy for anteromedialization of the tibial tubercle. The technique combines the concepts of Elmslie-Trillat and Fulkerson and modifies their techniques to produce an osteotomy that decreases lateral patellar pressure and centers the patella correctly in the trochlear groove.

Osteotomy of the Tibial Tubercle for Anteromedialization
Patellofemoral instability is a common cause of anterior knee pain, especially in younger and more active patients. Treatment of instability varies considerably depending on the patient's symptoms as well as the cause of the instability. Lateral instability has a particularly broad spectrum of treatment algorithms including patellar taping, arthroscopy, lateral release, medial patellofemoral li...

realign the knee extensor mechanism. Proximally, Insall realignment or variations with imbrication of the vastus medialis obliquis (VMO) and medial patellar retinaculum, combined with a lateral release, have been used extensively to improve patellar tracking. Distal realignment, in which the tibial tubercle is typically moved medially to improve patellar alignment, is the other common approach ...

The tibial tubercle (interchangeable with tuberosity) is the most distal anchor of the extensor mechanism and can serve as a tool in altering patellofemoral (PF) mechanics. Known collectively as distal realignment procedures, osteotomies of the tibial tubercle are a useful method to treat a variety of PF conditions by allowing coronal, axial, and sagittal plane adjustments of the patellofemoral...

Despite the fact that common surgical techniques for the treatment of genu varum usually correct the malalignment in the affected knee, these methods have significant complications and cause problems in the long term. Retro-tubercle opening-wedge high tibial osteotomy is among the newer techniques for the treatment of genu varum. The goal of this study was to compare the results of retro-tuberc...
