In-vitro evaluation of a force-sensing device for ligament balancing in TKA

Hannes Bleuler, Thomas Maeder, Denis Crottet

Component loosening and instability are common causes of dysfunction after Total Knee Arthroplasty (TKA) and it is generally assumed that such complications are due to tibio-femoral misalignment or ligamentous imbalance. During the surgery, the ligamentous ...
