Subject-Specific Knee Joint Motion Modeling
| Motivation |
| |
The knee joint is prone to injuries, such as osteoarthritis and torn ligaments, which often restrict its range of motion. To restore normal knee joint motion, complex surgical interventions are needed, whose outcome depends on the surgeons' experience as well as pre-operative planning. Even a slight mistake that happens during the surgery may result in abnormal knee joint motion and accelerate the degenerative process of the knee. Therefore, a subject-specific computational model of the knee joint is used in the pre-operative planning stage to predict possible surgical outcomes for a specific patient. |

| Research Goal |
| |
Our research goal is to develop method for modeling the knee joint motion specific to the subjects.

The knee consists of three main bones: the femur, the patella and the tibia. The following images illustrate various views of the bones.
