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:
