Using Intraoperative Sensing Technology to Evaluate Revision Total Knee Arthroplasty

January 3, 2025 updated by: Orthosensor, Inc.
This study will attempt to draw relationships between the soft-tissue related complications contributing to early TKA revision and the loading and positional patterns from intraoperative tibial trial sensors. The data from the sensors may enable the surgeon to address such soft-tissue abnormalities that may otherwise be unknown during traditional total knee revision procedures. The utilization of sensors should in theory, help diagnose the potential causes attributing to soft-tissue imbalance and may lead to a decreased need for an all component revision. Furthermore, the economic implications from converting a total revision to a partial revision could have a profound effect to the patient and healthcare provider such as decreased rehabilitation regimes and opportunity for cost savings. Eligible revision patients who agree to participate will be followed for a period of 12 months following the revision procedure. Patient reported outcomes measures (PROM) such as the 2011 Knee Society Score (KSS) and the Veterans Rand 12-Item Health Survey (VR-12) will be collected at baseline (pre-operatively) and at 6 weeks, 6 months and 12 months post-procedure. All outcomes will be scored to observe changes from baseline at 12-months. Cost-analyses of sensor-assisted revision TKA will be performed to include OR costs, facility and physician fees, as well as payments to post-acute collaborators such as SNFs, rehab hospitals, PT and home care providers. A quantitative analysis of commercial payer claims / usage data (e.g., CMS Medpar data) will be used to examine costs associated with traditional revision TKA procedures.

Cohorts and Interventions

Group / Cohort
Intervention / Treatment
Partial Revision
A "partial" revision will be indicated when only the tibial liner is changed or only the tibial liner with the tibial tray or only the tibial liner with the femoral component.
Procedure: VERASENSE
Sensor-Assisted Revision TKA
Other Names:
  • Sensor-Assisted TKA
Total Revision
A "total" revision will be indicated when all components are completely removed and replaced (tibial tray, femoral component and tibial liner).
Procedure: VERASENSE
Sensor-Assisted Revision TKA
Other Names:
  • Sensor-Assisted TKA

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Cause of Early TKA Revision
Time Frame: 12-months
The objective is to evaluate and link the possible causes of early TKA revision procedures using intraoperative sensors in effort to understand why knees fail in addition to examining the economic implications to the patient and hospital.
12-months

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Veterans Rand 12-Item Health Survey
Time Frame: Change from Baseline at 12-months
This survey is primarily used to measure health related quality of life, to estimate disease burden and to evaluate disease-specific impact on general and selected populations. The items on the questionnaire correspond to eight principal health domains including general health perceptions, physical functioning, role limitations due to physical and emotional problems, bodily pain, energy-fatigue , social functioning and mental health
Change from Baseline at 12-months
Knee Society Score
Time Frame: 12 months
This survey is subdivided into a knee score that rates only the knee joint itself and a functional score that rates the patient's ability to walk and climb stairs. Patient expectations as well as patient satisfaction are also evaluated.
12 months
