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 ...

Aim: Abnormal positioning of the patella, which superior position is defined as patella alta (PA), whereas inferior baja (PB). Most measurements patellar evaluations are time-consuming. In this study, we aimed to examine diagnostic accuracy visual evaluation according physeal line and determine inter- intraobserver agreement in MRI examinations. Material Methods: Knee examinations performed bet...

We reviewed the outcome of 146 Insall-Burstein II total knee replacements carried out in 121 patients over a period of nearly four years in a general orthopaedic unit. At a mean follow-up of ten years, 94 knees in 78 patients were available for review. Six patients (7 knees) were lost to follow-up and 37 (45 knees) had died. The clinical outcome using the scoring system of the Hospital for Spec...

Background The Insall-Burstein posterior-stabilized knee design was first developed in 1978 by adding a central cam mechanism to the articular surface geometry of total condylar prosthesis correct its problems being not “rolling back”. Since then, use (PS) implants arthroplasty (TKA) is becoming increasingly popular. However, one main disadvantages PS designs related amount bone removed during ...

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...

AIM To analyse the clinical symptoms, aetiology and biomechanical aspects related to Sinding-Larsen-Johansson (SLJ) disease. MATERIAL AND METHOD A case control study was conducted, analysing the following variables: age, gender, clinical follow up, side of body with the symptoms, sporting activity, radiological stage, presence of patella alta, presence of short hamstring tendons, and increase...

OBJECTIVE To retrospectively assess the early results of the NexGen Legacy posterior-stabilised total knee prosthesis, which is a newer version of the Insall-Burstein II posterior-stabilised implant. METHODS 48 consecutive elderly patients had 60 NexGen Legacy posterior-stabilised total knees. The mean follow-up duration was 21 months. Clinical evaluation was performed according to the Knee S...
