Accepts Healthy Volunteers
Healthy volunteers are participants who do not have a disease or condition, or related conditions or symptoms
An interventional clinical study is where participants are assigned to receive one or more interventions (or no intervention) so that researchers can evaluate the effects of the interventions on biomedical or health-related outcomes.
An observational clinical study is where participants identified as belonging to study groups are assessed for biomedical or health outcomes.
Searching Both is inclusive of interventional and observational studies.
|Eligible Ages||45 Years and Over|
This trial id was obtained from ClinicalTrials.gov, a service of the U.S. National Institutes of Health, providing information on publicly and privately supported clinical studies of human participants with locations in all 50 States and in 196 countries.
Phase 1: Studies that emphasize safety and how the drug is metabolized and excreted in humans.
Phase 2: Studies that gather preliminary data on effectiveness (whether the drug works in people who have a certain disease or condition) and additional safety data.
Phase 3: Studies that gather more information about safety and effectiveness by studying different populations and different dosages and by using the drug in combination with other drugs.
Phase 4: Studies occurring after FDA has approved a drug for marketing, efficacy, or optimal use.
The sponsor is the organization or person who oversees the clinical study and is responsible for analyzing the study data.

The open-label study aims to enroll up to 75 participants into the conventional guidance arm followed by 75 participants into the stereotactic guidance arm, in sequence. Detailed observational data will be collected during the surgical procedures, and participating patients will be evaluated at prescribed intervals (pre-operatively, and 2,4,6, and 12 months post-operatively) using survey instruments, clinical indicators, and routine radiologic outcomes. Radiologic outcomes will be assessed using standard x-rays that are obtained in the course of normal care for all patients who undergo total knee arthroplasty (TKA). A subset of the first 30 patients enrolled into each treatment arm will, in addition, be asked to voluntarily undergo a computed tomography (CT) scan of the lower extremity (hip, knee, and ankle joints) 8-12 weeks after surgery to measure 3-dimensional accuracy of prosthesis placement and limb alignment. Data collection will include: 1. Demographic and background information (age, sex, height, weight, social (occupation/employment), major comorbidity (broadly classified), smoking) 2. Patient reported outcome measures (Veteran's Rand 12-item Health Survey; 2011 Knee Society Score) 3. Physical Examination (knee range of motion, knee stability) 4. Details of the surgical operation 5. Operating room workflow details, including skin-to-skin surgical time 6. Post-operative disposition 7. Radiologic outcomes 1. Routine pre- and post-operative radiographs will be reviewed for limb alignment and evidence of prosthesis fixation 2. Post-operative CT scans (hip, knee, ankle) will be used to evaluate accuracy of placement of the TKA prosthesis (femoral and tibial components) and accuracy of limb alignment in the coronal, sagittal, and axial planes. The values measured from the post-operative CT scan will be compared to those of the final intra-operative plan; lack of difference between the two will constitute 'accuracy'. 8. Adverse events 9. Patients may optionally participate in an additional clinical follow-up visit at 2 years post-operatively, which will include the patient reported outcome measures, physical, examination, and radiographic examination.
: Conventional guidance
The conventional guidance will undergo TKA surgery with use of the Investigator's usual precision guided technique based on conventional instrumentation (mechanical and simple computer-assisted guidance techniques). For participants of the conventional guidance arm, the Investigator will employ the established technique he currently employs for all routine TKA procedures and would employ if the patient were not a participant in the study.
: Stereotactic guidance
The stereotactic guidance group will undergo their TKA surgery with use of a stereotactic guidance system.
Device: - Stereotactic guidance system
