Optimising knee therapies through improved

项目摘要

Our vision is that patients with knee pain receive the right treatment at the right time.In the UK, one third of people aged over 45 have sought treatment for osteoarthritis, and the disease costs the NHS over £5 billion per year. The knee is the most common site for osteoarthritis, with over four million sufferers in England alone. The aging population with expectations of more active lifestyles, coupled with the increasing demand for treatment of younger and more active patients, are challenging the current therapies for knee joint degeneration. There is a major need for effective earlier stage interventions that delay or prevent the requirement for total knee replacement surgery. There are large variations in patients' knees and the way that they function, and it is important that this variation is taken into account when treatments are developed, so that the right treatment can be matched to the right patient. Through this ambitious programme of research we will develop novel testing methods that combine laboratory-based simulation and computer modelling to predict the mechanical performance of new therapies for the knee and enable their design and usage to be optimised. Importantly these tests will take into account the variation in patients' anatomy and knee biomechanics, as well as variations in device design and surgical technique. This will enable different therapies, or different variants of a device, to be matched to different patient groups.The tools will be applied to existing treatments using clinical data to help validate that our model predictions are correct. The outcomes will better define which patients will benefit from a particular intervention and help optimise their usage. We will then apply the methods to new and emerging treatments, including regenerative devices, so that they can be tested and optimised before costly clinical trials take place. We will use these examples as case studies to demonstrate how the new testing methods can optimise the products before they reach the patient, and we will work with industry, standards agencies and regulators to promote the adoption of these methods across the sector. This programme will benefit patients, the NHS and the growing UK industry and science base that are developing new therapies for the knee.

我们的愿景是膝关节疼痛的患者在正确的时间得到正确的治疗。在英国，45岁以上的人中有三分之一寻求骨关节炎的治疗，这种疾病每年花费NHS超过50亿GB。膝关节是骨性关节炎最常见的部位，仅在英格兰就有400多万患者。随着人口老龄化，人们对更活跃的生活方式的期望，再加上对更年轻、更活跃的患者的治疗需求不断增加，正在挑战目前的膝关节退行性变治疗方法。主要需要有效的早期干预措施，以延迟或阻止对全膝关节置换手术的要求。患者的膝盖及其功能有很大的差异，在开发治疗方法时考虑到这种差异是很重要的，这样正确的治疗才能与正确的患者相匹配。通过这一雄心勃勃的研究计划，我们将开发新的测试方法，将基于实验室的模拟和计算机建模相结合，以预测膝关节新疗法的机械性能，并使其设计和使用得到优化。重要的是，这些测试将考虑到患者解剖和膝关节生物力学的差异，以及设备设计和手术技术的差异。这将使不同的疗法或设备的不同变体能够与不同的患者群体相匹配。这些工具将应用于使用临床数据的现有治疗方法，以帮助验证我们的模型预测是正确的。结果将更好地定义哪些患者将从特定的干预中受益，并帮助优化他们的使用。然后，我们将把这些方法应用于新的和新兴的治疗方法，包括再生设备，这样它们就可以在昂贵的临床试验发生之前进行测试和优化。我们将使用这些例子作为案例研究，展示新的测试方法如何在产品到达患者手中之前对其进行优化，我们将与行业、标准机构和监管机构合作，在整个行业推广采用这些方法。这项计划将使患者、英国国民健康保险制度以及正在为膝盖开发新疗法的不断增长的英国工业和科学基础受益。
