Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This is an observational study to understand the effects of soft-tissue balancing on gait, function and rehabilitation potential after sensor-assisted Total Knee Arthroplasty

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The primary objectives of this study are to understand the effects of soft-tissue balancing on Gait, function and rehabilitation potential after sensor-assisted Total Knee Arthroplasty and to correlate Intra-operative subjective feel with OrthoSensor Outputs

Secondary objectives are to quantify and observe pain medication use, swelling, muscle strength and girth, gait efficiency, patient satisfaction, activity levels, functional return (i.e., back to work, resume normal activities) and patient perception of a balanced knee

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Device Arm

A prospective series of 10 patients will receive sensor-guided TKA using the this special Orthosensor™ VERASENSE™ Knee System assisted surgery for optimization of soft tissue balance

Group Type EXPERIMENTAL

Orthosensor™ VERASENSE™ Knee System

Intervention Type DEVICE

A group of patients will receive a total knee arthroplasty using the Orthosensor device

Standard of Care

10 patients will receive standard of care. Prior to cementing final implants, VERASENSE will be utilized with the standard of care group with the surgeon blinded to the data.
