Anterior knee pain is one of the most common causes of persistent problems after implantation of a total knee replacement. It can occur in patients with or without patellar resurfacing. As a result of the surgical procedure itself many changes can occur which may affect the delicate interplay of the joint partners in the patello-femoral joint. Functional(More)
Lateral ankle sprains are common musculoskeletal injuries. The objective of this study was to perform a systematic literature review of the last 10 years regarding evidence for the treatment and prevention of lateral ankle sprains. Pubmed central, Google scholar. Meta-analysis, prospective randomized trials, English language articles. Surgical and(More)
PURPOSE In this study we evaluated the ability of inducing activation of the enzyme indoleamine 2,3-dioxygenase (IDO) for the development of a new adjuvant therapy of osteosarcomas. The pathway that has described in the literature states that IDO activity is elevated by IFN-gamma. This mechanism is important because the increased IDO activation induces an(More)
BACKGROUND Osteosarcomas are primary malignant tumors of bone or soft parts arising from bone-forming mesenchymal cells. Despite dramatic therapeutic advances, namely neo-adjuvant and adjuvant chemotherapy, progress is at a plateau. Cytokine-mediated gene therapy might represent a further advance in the therapy of the osteosarcoma. MATERIALS AND METHODS(More)
OBJECTIVE Vertebral metastases are quiet common and may result in vertebral collapse, spinal instability, and progressive neurological compromise. An anterior approach is the accepted method for decompression and stabilization by vertebral replacement. There is still need for discussion regarding the material of the replacement device. Here, the authors(More)
It has been previously shown that exercise programs for patellofemoral pain syndrome (PFPS) can be supported by medially directed taping. Evidence supporting the use of patellar braces is limited because previous studies have been low quality. The aim of this study is to compare the outcomes of patients with PFPS after treatment with a medially directed(More)
There is a lack of consensus regarding biomechanical effects of unloader braces for the treatment of medial osteoarthritis (OA) of the knee. The purpose of this study was to perform a systematic review of studies examining the biomechanical effect of unloader braces. A systematic search for articles about the biomechanical effect of unloader braces was(More)
Neurilemomas are benign tumours arising from peripheral nerves with a Schwann cell sheath. They are normally painless and slowly growing, rarely causing motor disturbances. Neurilemomas are most common in the cranial nerves, in the trunk, the upper and lower extremities, but may appear anywhere. Especially rare are neurilemomas of the lateral peroneal(More)
BACKGROUND Patellofemoral pain syndrome (PFPS) is a frequent cause of anterior knee pain predominantly affecting young female patients who do not have significant chondral damage. Development of PFPS is probably multifactorial, involving various knee, hip, and foot kinematic factors. Biomechanical studies have described patellar maltracking and dynamic(More)
The patellofemoral pain syndrome (PFPS) is a possible cause for anterior knee pain, which predominantly affects young female patients without any structural changes such as increased Q-angle or significant chondral damage. This literature review has shown that PFPS development is probably multifactorial with various functional disorders of the lower(More)
