Modelling a Knee Ligament Repair Device

Ligaments in the knee that connect the femur to the tibia are often torn during a sudden twisting motion, which results in instability in the knee. In such cases ligament repair surgery may be an effective treatment where the ligament involved is replaced with a piece of healthy tendon which is grafted into place to hold the knee joint together. A novel device for use in knee ligament repair surgery has been designed, which aims to reduce damage to the ligament grafts used and to minimize post-surgery complications. To evaluate the efficacy of the design the device has been modeled as it would be subjected to static forces while joining the bones together.
