Ligament balancing in performing TKA is an upcoming topic to improve the results in TKA. A well balanced knee is working more proper together with the muscular stabilizing structures. Dynamic ligament balancing (DLB)R should give us the opportunity to check the balance of the ligaments at the beginning and the end of the surgery before implanting the definitive prosthesis. It is a platform independent, single-use device, which can be combined with all common types of knee prosthesis. DLBR consists of a set of 10 different sizes of baseplates including a feather of 15 to 20N (A). Connected to a tablet all datas can be shown during surgery and stored for patient security. During the surgery after calibrating the tibial cut is performed first, where it should be 90° to the longitudinal axis respecting the right slope. Measurement before femoral cuts are performed and give an information about the joint angle according to the anatomical and load axis. The femoral cuts can be performed with the original cutting block of every set in extension and flexion. After positioning the femoral trial, testing is repeated and should show a balanced situation over all the ROM. The overall period datas were stored and compared to the subjective feeling of the patients.Introduction
