Development of a Malaligned Patella Testing Model
ثبت نشده
چکیده
INTRODUCTION Wear and fracture of patellar components has been reported in the literature as a failure mode for both cemented and press fit patellar components [1-5]. Malalignment of the patellar components can cause higher contact stresses, which can lead to excessive wear, delamination, and/or fracture of the component. Therefore, in vitro testing of the patella in a clinically relevant malaligned condition is necessary demonstrate adequate performance of the patellar component and to assesses the endurance of its fixation features under severe loading conditions. As a result, the purpose of this study was to develop an in vitro malaligned patella test model using a knee joint simulator.

The influence of malalignment and ageing following sterilisation by gamma irradiation in an inert atmosphere on the wear of ultra-high-molecular-weight polyethylene in patellofemoral replacements
Complications of patellofemoral arthroplasty often occur soon after implantation and, as well as other factors, can be due to the design of the implant or its surgical positioning. A number of studies have previously considered the wear of ultra-high-molecular-weight polyethylene patellae following suboptimal implantation; however, studies have primarily been carried out under a limited number ...
متن کاملTesting the reproductive benefits of aggregation: the limpet Patella vulgata shows no evidence of synchrony in gonad development
Group living is ubiquitous, yet causal explanations are not fully tested. Evidence for a reduction in predation risk is clear, and there is support for reduction of risk from the abiotic environment. Potential reproductive benefits are less well understood, especially for non-lekking, externally fertilising animals which form medium-term aggregations. We used Patella vulgata to test the model t...
متن کاملGiant cell tumor of patella: A case report and review of literature
Objective: Patella is a sesamoid bone which develops in the quadriceps tendon. It is an uncommon site for neoplasms. The most common primary tumors which involve patella are benign. These include chondroblastoma, giant cell tumor (GCT) and aneurysmal bone cyst. Malignant lesions are less common in patella. These encompass metastasis, osteosarcoma and hemangioendothelioma. The most common compla...
متن کاملChondroblastoma of the patella treated with curettage and bone graft: a case report
Abstract Patella is a relative uncommon site for chondroblastoma. Most of cases of chondroblastoma in patella reported in literature are treated with patellectomy. We treated a large chondroblastic lesion in patella of an 18- year-old male with curettage, burring & bone graft and the result was satisfactory after 3 years post operation.

In recent years, several research activities have been conducted to develop knowledge in analysis, design and optimization of compressor anti-surge control system. Since the anti-surge control testing on a full-scale compressor is limited to possible consequences of failure, and also the experimental facility can be expensive to set up control strategies and logic, design process often involves...
