项目摘要

PROJECT SUMMARY/ABSTRACT This urgent competitive revision responds to NIAMS Notice of Special Interest (NOSI) NOT-AR-23-015. The parent study (NIAMS R01 AR077452) aims to develop novel quantitative MRI techniques (accelerated MR T1ρ and T2 mapping) to evaluate cartilage compositional changes and early degeneration in patients after anterior cruciate ligament reconstruction (ACLR), a population at high risk of developing post-traumatic osteoarthritis (PTOA). In this study, we aim to explore the mechanisms in musculoskeletal (MSK) pain and identify novel imaging (knee and brain) markers for pain after ACL injury and surgery, and at early PTOA. The proposed study will significantly expand the scope of the parent study from only focusing on structural changes (‘disease’) to one evaluating patient symptoms (‘illness’, in particular pain) in OA. With a novel multi-modal approach that includes advanced knee and brain MRI, our group will, for the first time, investigate central neural system (CNS) alterations in pain post orthopaedic injury/surgery, and in early PTOA. The study outcomes will provide critical preliminary data to formulate specific hypotheses for MSK pain, and will develop novel imaging techniques that can be utilized for future large-scale studies of pain mechanisms following orthopaedic injury/surgery and in OA/PTOA, an under-investigated area with pressing clinical needs. As such, the proposed study is aligned with the NOSI Goal A: Generate supporting evidence towards a future innovative study or new scientific direction in pain research in musculoskeletal diseases, in the areas of interest of novel pain imaging technologies. OA affects 30+ million people in the US and 300+ million people worldwide. It presents tremendous health and socioeconomic burdens with health care costs and work loss. Pain is the major factor that significantly impairs quality of life, leads to disability, and prompts patients for clinical visits and eventually total joint arthroplasty for OA. Opioid prescriptions for severe OA/PTOA pain and pain after orthopaedic injury are common, which constitutes a significant contribution to the national opioid crisis due to its high prevalence. A better understanding of the mechanisms of post-injury/surgery and OA/PTOA pains and identifying biomarkers that are associated with or predict MSK pain, the gap the proposed study aims to fill, will provide useful guidance on developing novel therapeutic targets for pain relief in OA and other MSK disorders. The proposed study presents a significant and timely expansion of the parent study. It will leverage the resources from the parent study and provide a unique opportunity to investigate relationship between joint structural damages, CNS alternations, and pain in a novel early OA model (PTOA, after orthopaedic injury and surgery). The study outcomes will provide valuable insights to MSK pain mechanisms, help identify new treatment targets for pain relief in this huge patient population, and eventually help with providing scientific solutions to battle against the ever- increasing opioid epidemic in the US.

项目总结/摘要本紧急竞争性修订是对NIAMS特别关注通知（NOSI）NOT-AR-23-015的回应。的母研究（NIAMS R 01 AR 077452）旨在开发新型定量MRI技术（加速MR T1ρ 和T2映射），以评估患者在前路手术后的软骨成分变化和早期退变。交叉韧带重建（ACLR），创伤后骨关节炎高危人群（PTOA）。在这项研究中，我们的目的是探索肌肉骨骼（MSK）疼痛的机制，并确定新的 ACL损伤和手术后以及PTOA早期的疼痛成像（膝关节和脑）标记物。拟议研究将显著扩大母研究的范围，从仅关注结构变化（“疾病”）评估OA患者症状（“疾病”，特别是疼痛）的方法。采用新颖的多模式方法，包括先进的膝关节和脑MRI，我们的团队将首次研究中枢神经系统（CNS）骨科损伤/手术后疼痛和PTOA早期的变化。研究结果将提供关键的初步数据，制定具体的假设MSK疼痛，并将开发新的成像技术，可用于未来骨科损伤/手术后疼痛机制的大规模研究， OA/PTOA，一个研究不足的领域，具有迫切的临床需求。因此，拟议的研究符合 NOSI目标A：为未来的创新研究或新的科学方向提供支持证据，在肌肉骨骼疾病的疼痛研究，在新的疼痛成像技术感兴趣的领域。 OA影响美国3000多万人和全球3亿多人。它代表着巨大的健康，社会经济负担与医疗保健成本和工作损失。疼痛是显著损害生活质量，导致残疾，并促使患者进行临床访视，最终进行全关节置换术， OA。阿片类药物处方用于严重OA/PTOA疼痛和骨科损伤后疼痛很常见，由于其高流行率，对全国类阿片危机作出了重大贡献。更好的了解损伤后/手术和OA/PTOA疼痛的机制，并确定与MSK疼痛相关或预测MSK疼痛，所提出的研究旨在填补的差距，将提供有用的指导，开发用于缓解OA和其他MSK疾病疼痛的新治疗靶点。拟议的研究提出对母研究进行了重大而及时的扩展。它将利用母研究的资源，提供了一个独特的机会，调查关节结构损伤，中枢神经系统的变化，一种新型早期OA模型（PTOA，骨科损伤和手术后）中的疼痛。研究结果将提供有价值的见解MSK疼痛机制，帮助确定新的治疗目标，缓解疼痛，庞大的患者群体，并最终帮助提供科学的解决方案，以对抗不断- 阿片类药物在美国日益流行。
