Development of a Pneumatic Tensioning Device for Gap Measurement during Total Knee Arthroplasty

摘要

BackgroundDespite the importance of soft tissue balancing during total knee arthroplasty (TKA), all estimating techniques are dependent on a surgeon's manual distraction force or subjective feeling based on experience. We developed a new device for dynamic gap balancing, which can offer constant load to the gap between the femur and tibia, using pneumatic pressure during range of motion.
