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...

  Abstract   Background: The purpose of this study was to evaluate the significance of the Q   angle with respect to the patella position. We assess the correlation between the Q angles (calculated by clinical exam) in different positions and CT indices (with more   impression on TTTG).   Method: Atotal number of 68 knee joints of 50 cases entered the study. Clinical   examination was used to m...

Background: There are a number of different factors that are thought to play a role in patellar instability, including injuries to the medial patellofemoral ligament (MPFL), trochlear dysplasia, patella alta, and an increased tibial tuberosity-trochlear groove (TT-TG) distance. Objective: To use MRI to assess injury patterns to the MPFL, trochlear dysplasia, patellar height, and TT-TG distance ...

Objectives: Patellofemoral dislocation, the most severe presentation on spectrum of patellar instability, is common in adolescent populations. Trochlear dysplasia an integral component disorder, and procedures aimed at correcting instability by addressing this are often necessary. A theoretical risk injury to distal femoral physis exists these surgeries. At our institution, a thick-flap sulcus ...
