Abstract

Soft tissue balancing in total knee replacement (TKR) is paramount to obtain optimal stability of the joint, improve kinematics, produce equal load on each side of the prosthetic components and decrease component wear [1]. Whilst the role of computer navigation is well established as the most accurate means of obtaining desired coronal and sagittal alignment, its role in soft tissue balancing is more recent. The use of navigation data allows the surgeon to recognise imbalance including midflexion instability, excessive tightness in flexion, failure to resolve flexion contractures and persisting pathological recurvatum. Navigation derived information allows the surgeon a real time assessment of stability throughout the flexion arc and importantly these objective measurements enable the surgeon to address the abnormalities and confirm resolution before the patient leaves the operating room
