BACKGROUND Our study aimed to investigate whether geometrical features (size, shape, or alignment parameters) of the femoral condyle affect the morphology of the trochlear groove. METHODS Computed tomography models of 195 femurs (97 and 98 knees from male and female subjects, respectively) were reconstructed into three-dimensional models and categorised into four types of trochlear groove mor...

The clinical diagnosis of femoral trochlear dysplasia primarily relies on imaging. In the past, plain imaging was the major source of diagnosis. The present study investigated the application of magnetic resonance imaging (MRI) in the objective assessment of severe femoral trochlear dysplasia. A retrospective analysis was performed on knee MRIs from 30 normal subjects (30 knees) and 59 patients...

To prevent patella infera in open wedge high tibial osteotomy, a new operation technique was developed. Instead of a proximal tibial tuberosity osteotomy, a distal osteotomy was performed and the tuberosity was fixed with one screw to the tibia. Initial experience in 17 patients was evaluated and compared with results of 20 patients with open wedge high tibial osteotomy with proximal tuberosity...

OBJECTIVE To assess signalment, outcomes, and complications for dogs surgically treated for medial patellar luxation (MPL) with a combination of lateral retinacular imbrication and tibial crest transposition procedures without femoral trochlear groove deepening techniques, and to determine whether osteoarthritis progressed in these patients during the 8-week period following surgery. DESIGN R...

OBJECTIVES To evaluate morphological parameters of the femur, tibia, and patella in Toy Poodles with medial patellar luxation (MPL) using three-dimensional (3D) computed tomography (CT) and to compare these parameters between radiography and CT. METHODS Thirty-five hindlimbs of Toy Poodles were divided into normal and grade 2 and 4 MPL groups. The anatomical and mechanical lateral proximal fe...

The influence of the tibial tuberosity conformation on cranial cruciate ligament (CrCl) rupture was evaluated and the size of the tibial tuberosity of healthy dogs (group H) was compared with dogs with CrCl rupture (group R) and dogs treated by tibial tuberosity advancement (TTA) (group T). The medio-lateral radiographs of 219 stifle joints were evaluated. Relative tibial tuberosity width (rTTW...

Introduction: Intramedullary nailing has been used frequently for the treatment of tibial diaphyseal fractures. Chronic anterior knee pain has been considered the most frequent post-operative complication of this technique. We investigated the relationship between anterior knee pain and position of nail tip in proximal tibia. Methods: 103 patients were selected among patients who underwent inte...

IntroductionLateral retinacular release, tibial tuberosity elevation, and tibial tuberosity elevation with medial transposition are commonly done at our institution in patients who have failed conservative therapy for patellofemoral pain syndrome. Our clinical results reflect the findings of multiple authors and are not always satisfactory. Usually, the retropatellar surface is referenced in bi...

BACKGROUND Medial patellofemoral ligament (MPFL) reconstruction has become one of the most common and widely used procedures to regain stability among patients with recurrent lateral patellar dislocation. While recent studies demonstrated low recurrence rates, improved patient-reported outcome measures, and a high rate of return to sports, limited literature explored its effectiveness as an iso...

Background: Recurrent patellar dislocation (RPD) and habitual (HPD) in flexion are frequently encountered children adolescents. Purpose: To compare the radiological features of RPD HPD Study Design: Cross-sectional study; Level evidence, 3. Methods: Imaging data were collected from patients aged 9 to 15 years who received surgical treatment for or at a single institution between June 2015 Septe...
