Calibrated Tensioner For Total Knee Arthroplasty Gap Balancer, Lauren Henigman, Jaypreet Dhanota, Corey Catuara

Biomedical Engineering

The purpose of this project was to design a device that interfaces with the previously created gap balancer to simultaneously measure the gap between the femur and tibia and measure the tension in the ligaments of the knee. First, we met with Dr. Delagrammaticas to outline the key customer requirements: we wanted the device to be precise, sterilizable, reliable, and compatible with the gap balancer. Based on the customer requirements, we outlined the specifications that would drive our design and testing, which included precision, ease of use, size, and material properties. The design process began by using a morphology to …
