Advances in Computer Assisted Mosaic Arthroplasty

软骨退变是一种广泛存在的问题，主要发生在膝盖、脚踝和肩部。对于年轻、活跃的患者，早期软骨置换可以大大提高生活质量，可以推迟或消除最终对假体关节置换的需求，从而为加拿大医疗保健系统节省大量资金。马赛克关节成形术是一种将软骨和骨块从关节的非负重区移植到软骨缺损处的外科手术。我们在以前的研究中已经表明，计算机辅助马赛克关节成形术(CAMA)比传统马赛克关节成形术有更好的临床结果。这项拟议的研究将培养四名研究生和三名本科生，将开发计算机算法和用户界面，以在三个领域改进CAMA的交付：

Cartilage degeneration is a widespread problem which occurs predominantly in the knee, ankle, and shoulder. For younger, active patients, early cartilage replacement can result in a much improved quality of life and can delay or eliminate the eventual need for prosthetic joint replacement, with substantial savings to the Canadian healthcare system. Mosaic arthroplasty is a surgical procedure in which plugs of cartilage and bone are transplanted from non-load-bearing areas of the joint to the site of the cartilage defect. We have shown in previous research that computer-assisted mosaic arthroplasty (CAMA) results in better clinical outcomes than conventional mosaic arthroplasty. The proposed research, which will train four graduate and three undergraduate students, will develop computer algorithms and user interfaces to improve the delivery of CAMA in three areas:
