PILOT STUDY: Gait and Functional Improvement in Total Knee Arthroplasty With the Use of Verasense for Soft Tissue Balancing: A Randomized, Double-Blind, Controlled Trial

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government. Read our disclaimer for details. Identifier: NCT02290119

Brief Summary:

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 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)
  • Patient perception of a balanced knee

Arm Intervention/treatment
Sham Comparator: Control - Without the use of Verasense
Total Knee Replacement without the use of intraoperative sensors
Procedure: Control - Without the use of Verasense
Patients in this cohort will undergo manual total knee replacement without the use of Verasense

Active Comparator: Sensor-assisted TKR (Verasense)
Total Knee Replacement with the use of intraoperative sensors
Device: Sensor-assisted TKR (Verasense)
Verasense is a single use, disposable device embedded with microelectronics into a standard tibial trial to provide dynamic, intraoperative feedback regarding limb alignment, tibiofermoral position and quantitative pressure at peak contact points in the medial and lateral compartments during total knee replacement surgery. Utilizing sensor-derived data, the surgeon can now evaluate intercompartmental loading throughout the range of motion, and correct for soft-tissue abnormalities while receiving real-time feedback regarding joint balance.

Primary Outcome Measures :
  1. Rehabilitation Potential [ Time Frame: 6 Months ]

Secondary Outcome Measures :
  1. Knee Society Pain and Functional Scoring [ Time Frame: 6 month ]
  2. Forgotten Joint Assessment [ Time Frame: 6 month ]
  3. 3D Gait Analysis [ Time Frame: 6 Month ]
