Abstract
Total knees today are performed with the use of standard trials that the surgeon utilises to define appropriate implant rotation, range of motion, and soft tissue balance.
This “feel” based approach is very subjective, and lacks a quantifiable approach to interpret our intra-operative knee assessment.
Sensor-based trials are embedded into the specific knee designed tibial trial, and wirelessly displays data related to the implant's position and ligament tension.
The surgeon can now identify malrotation, soft tissue imbalance, and instability through a full ROM. The surgeon can see dynamic responses to ligament releases, alignment changes, and implant adjustments. As Insall taught us; a TKR is a soft tissue procedure, and a “balanced” knee will demonstrate improved outcomes and greater patient satisfaction. Smart Trials allow us to discuss how our intra-operative techniques affect our patient's outcomes.
This surgery will utilise Smart Trials during a Cruciate Retaining TKR.
