“…Therefore, any inter-structure rheological effects can be assumed to be equal and opposite. Soft tissue imbalance has been defined in both extension and 90" of flexion as the geomeuy of the resultant trapezoid [16]. Soft tissue balance quantified in these terms should be quoted in conjunction with the angle of the femoral and tibia1 cuts, to allow the absolute comparison between patients.…”

The measurement of soft tissue imbalance during total knee replacement has long been discussed. The main problem with its assessment was the datum point for in measurement.Surgical instrumentation in the past has assumed that the soft tissues of the knee joint act in a way similar to a mesh work of connecting elastic strings. This is incorrect, however, since the soft tissues have viscoelastic properties with non-linear load-elongation curves. Therefore, surgical instrumentation has been designed to measure soft tissue imbalance at the time of surgey, assuming that the soft tissue structures are viscoelastic. Some sample results of the system in use are presented, showing that soft tissue imbalance can be drastically reduced surgically once the correct design for its measurement has been achieved.

“…Several studies which investigated soft tissue balancing in TKA, quantifying gap kinematics between the femur and the tibia using a tensor device, have been published [3,12,22,25,28]. However, gap kinematics using a tensor device in UKA has not been well reported.…”

“…The second generation of tensor devices which were quantitatively applied and objective with the measurement under fixed torque or load were commercially available [16][17][18][19][20] or individually developed or modified [21][22][23][24]. Using the tensor, the following parameters can be calculated from the values: joint component gap (joint center gap) and varus ligament balance (varus angle) (Fig 2).…”
