BACKGROUND Habitual patellar dislocation is not common in clinical practice, but it has a deep impact on the patient's lifestyle and movement. There has been no large case-control study on habitual patellar dislocation, and the management of it is still controversial. The aim of this study was to observe the efficacy of the modified Fulkerson procedure on patients with habitual patellar disloca...

We evaluated the outcome in a series of patients with recurrent patellar dislocation who had either medial transfer of the tibial tuberosity and lateral release or an isolated lateral release as the primary treatment. The decision to use one or other procedure was based on a pre-operative distance between the tibial tuberosity to the trochlear groove (TTTG) of less than 10 mm to include the tib...

Purpose: To compare various values in computed tomography (CT) scanning between patella dislocation patients and health controls, to define the difference between the two groups, and to determine the rate of patellofemoral anatomical deformities in patients, providing relevant evidence for the appropriate treatment. Method: 100 health controls and 100 patients with patella dislocation from 2005...

To the Editor: I read with interest the paper by Sillanpàà et al. [1] entitled ‘‘Ligament Reconstruction Versus Distal Realignment for Patellar Dislocation’’ published in the June 2008 issue. I congratulate the authors on their study, for the longterm followup and for the comparative study with distal realignment. However, I ask for clarification of two issues. First, what are the indications f...

OBJECTIVE Patellofemoral instability is common and affects a predominantly young age group. Chondral injury occurs in up to 95%, and includes osteochondral fractures and loose bodies acutely and secondary degenerative changes in recurrent cases. Biomechanical abnormalities, such as trochlear dysplasia, patella alta, and increased tibial tuberosity-trochlear groove distance, predispose to both r...

Abstract The aim of this study was to report patellar groove replacement in a 6-year-old domestic short hair cat with chronic unilateral pelvic limb lameness and severe femoro-patellar osteoarthritis due medial luxation. This is case report. Computed tomographic scan the affected revealed marked periarticular osteophytosis, trochlear ridge erosion, flattening femoral trochlea, ectopic pseudo-tr...
