OBJECTIVE Open reduction and internal fixation of posterolateral tibial plateau fractures. INDICATIONS Tibial plateau fractures involving the posterolateral quadrant. CONTRAINDICATIONS Critical soft-tissue conditions. Tibial plateau fractures which do not involve the posterolateral quadrant. SURGICAL TECHNIQUE 90 degrees side positioning on the(More)
INTRODUCTION Patellar dislocation is a common knee injury with mainly lateral dislocations, leading to ruptures of the medial patellofemoral ligament in most of the cases. Even though several prognostic factors for patellofemoral instability have been identified so far, the appropriate therapy for patients with patellar dislocation remains a controversial(More)
UNLABELLED An isopropanolic extract (iCR) from the rhizomes of Cimicifuga racemosa (black cohosh) is used an alternative in the treatment of menopausal symptoms, and animal studies suggest positive skeletal effects. iCR stimulated osteoblastic OPG protein secretion by 3- to 5-fold as early as 12 h without affecting RANKL expression. The iCR effect,(More)
Knowledge of the basic mechanisms controlling osteogenesis and adipogenesis might provide new insights into the prevention of osteoporosis and age-related osteopenia. With the help of magnetic cell sorting and fluorescence activated cell sorting (FACS), osteoblastic subpopulations of mesenchymal progenitor cells were characterized. Alkaline phosphatase (AP)(More)
Raloxifene reduces bone loss and prevents vertebral fractures in postmenopausal women. Its skeletal effects are mediated by estrogen receptors (ER) and their modulation of paracrine osteoblastic factors. Receptor activator of nuclear factor-kappa B ligand is essential for osteoclasts and enhances bone resorption, whereas osteoprotegerin (OPG) neutralizes(More)
AIM The diagnosis and treatment of patellar dislocation is very complex. The aim of this study is to give an overview of the biomechanics of the patellofemoral joint and to point out the latest developments in diagnosis and treatment of patellar dislocation. METHOD The authors electronically searched Medline, Cochrane and Embase for studies on the(More)
As more children and adolescents are involved in sporting activities, the number of injuries to immature knees rises. We will focus on three entities: ruptures of the anterior cruciate ligament, patellar dislocation, and meniscal injuries. There is a trend in recent literature toward early reconstruction of the anterior cruciate ligament in children and(More)
Most dislocations of the patella occur during sports activities. The entities instability, maltracking and loss of tracking should be defined by patient history, clinical examination and radiological evaluation including magnetic resonance imaging (MRI). Based on these criteria a new classification of patella dislocations (5 types) was established which(More)
The aim of the study was to examine whether a rupture of the anterior cruciate ligament (ACL) in patients with open growth plates should be treated by surgery or conservatively. An electronic search was performed in MEDLINE, the Cochrane controlled trial register, Embase, and Medpilot. Ten studies including 154 patients were analyzed regarding conservative(More)
Minimally invasive and arthroscopic procedures have become an integral part of orthopedics and arthroscopy of the knee in particular has extensively evolved during recent years. Therefore, the purpose of this article is to show the indications and possibilities and also the limitations of arthroscopy-assisted fracture fixation of the knee joint. Based on(More)
