Abstract

Osteoarthritis (OA) is a degenerative disease of the knee joint caused by the formation of cracks within the collagen fibers of the articular cartilage. Current research is directed towards less invasive procedures for treating this degenerative disease using tissue engineering and 3D bioprinting. Therefore, it is crucial to obtain the exact shape of the damaged tissue, reconstruct the original shape of the tissue, and estimate the volume and area resulting from the wear of the contact surfaces. The study used the tibial plateau of a patient with OA that was removed during total knee arthroplasty, and the data was collected using a 3D scanner. After the reconstruction of the tibial plateau, an assessment of the area and volume of wear on the medial condyle of the tibia was performed, along with a FEM analysis of the real and approximate shape of the cartilage tissue. In this way, it is possible to simulate and create a patient-specific 3D model with a reconstructed wear volume, which can be highly attractive for future treatment strategies for cartilage damage or early stages of OA.
膝骨关节炎软骨体积损失的评估——病例研究
骨关节炎(OA)是一种膝关节退行性疾病,由关节软骨的胶原纤维形成裂缝引起。目前的研究方向是利用组织工程和3D生物打印技术治疗这种退行性疾病的侵入性更小的方法。因此,获得损伤组织的准确形状,重建组织的原始形状,并估计接触面磨损产生的体积和面积至关重要。该研究使用了在全膝关节置换术中切除的OA患者的胫骨平台,并使用3D扫描仪收集数据。胫骨平台重建后,对胫骨内侧髁的磨损面积和体积进行评估,并对软骨组织的真实形状和近似形状进行有限元分析。通过这种方式,可以模拟和创建具有重建磨损体积的患者特定3D模型,这对于未来软骨损伤或早期OA的治疗策略具有很高的吸引力。
