the balanSScer
The balanSScer suggests the optimal knee-balance for each individual patient, visualized into a real-time “stress-strain curve”.
A curve representing the individual’s tension of the ligaments so each surgeon can reproduce the original knee balance…
“no averages, no one-size-fits-all approach”
The Need for Optimal Balance Control
The Need for Optimal Balance Control
Soft tissue balance is the critical determinant of successful outcomes in total knee arthroplasty.
Accurate intra-operative measurement of collateral ligament strain is essential.
20% of patients report dissatisfaction due to persistent pain, stiffness, or instability.
Mechanical Alignment for Total Knee Arthroplasty, It is the End of an Era.
Making the best possible surgical decision for a patient involves combining scientific evidence with clinical experience and understanding patient’s expectations.
Surgical Sensors aims to reproduce normal ligament laxities and knee biomechanics.
Avoid Ligament Releases During Total Knee Arthroplasty (TKA). Objective feedback during surgery, reduces the need for ligament releases.

Optimal Measurement and Knowledge Gain
Optimal Measurement and Knowledge Gain
Optimal position of the replaced knee is reliant on correct tension of the soft tissue envelope. Matching the implant’s constraint level with the patient’s native ligament properties is crucial. Over-constraining the knee may cause stiffness, while under-constraining can result in instability.
The balanSScer with the smart screwdriver measures the tibiofemoral gaps under controlled distraction and provides correct assessments of ligament tension. In the past, soft tissue balancing in TKA was performed subjectively, based on the surgeon’s unquantified assessment = feel and eyeballing!
Sensor-Balanced Total Knee Arthroplasties: A Paradigm Shift
Sensor-Balanced Total Knee Arthroplasties: A Paradigm Shift
Surgical Sensors evaluates the properties of the soft tissue envelope by measuring the stiffness transition point on a stress/strain curve. The balanSScer determines the optimal position Δl when the force required to transition from laxity to stiffness therefore reflecting precise ligament pre-tension and balance. Stress-strain analysis offer valuable tool to address the limitations of subjective assessments, improving soft tissue balance and patient outcomes.
The technology is the subject of European patent application EP 24207376.5, titled "Surgical tool system with a smart screwdriver", filed by Surgical Sensors bv.
