The knee anterior cruciate ligament which connects the femur to the tibia is often torn during sudden twisting motions resulting in knee instability with surgery being an effective treatment where the torn ligament is replaced with a graft. This study provides qualitative stress information on a restored knee which has been repaired using a novel device. This device has been designed to reduce graft damage and to minimize post-surgery complications. The device as well as the intact knee have been modelled in 3D and studied using finite elements to assess the mechanical behaviour of the device under different loads. Results are evaluated and compared to equivalent published works. They showed that high stresses appear where tendons wrap around objects like the securing pin of the knee ligament repair device, while the highest stresses are away from the repair device components indicating that the device design does not affect the graft. Developed stresses were within the tendon elastic range, and load case direction does not affect significantly the developed stresses on the circumference of tendons in the most stressed region.
