Total knee arthroplasty (TKA) is a common procedure designed at alleviating pain and restoring function in patients with advanced osteoarthritis.

Despite this procedure being established, studies report a 5-20% dissatisfaction rate. Anterior knee pain being one of the major causes of dissatisfaction is thought to be related to abnormal soft tissue tensions following TKA.

A team of researchers at the University of Sydney is tackling the challenge of designing a minimally invasive instrumentation capable of assessing the tension in soft tissue structures and thus equipping orthopaedic surgeons with tools necessary to optimise TKA procedure and reduce post procedural pain.
