Outcome Measures

Primary Outcomes (15)

  • Knee Injury and Osteoarthritis Outcome Score

    KOOS Scores range from 0 to 100 with a score of 0 indicating the worst possible knee symptoms and 100 indicating no knee symptoms

    pre-operatively

  • Knee Injury and Osteoarthritis Outcome Score

    KOOS Scores range from 0 to 100 with a score of 0 indicating the worst possible knee symptoms and 100 indicating no knee symptoms

    6 weeks post-operatively

  • Knee Injury and Osteoarthritis Outcome Score

    KOOS Scores range from 0 to 100 with a score of 0 indicating the worst possible knee symptoms and 100 indicating no knee symptoms

    3 months post-operatively

  • Force generated by operative extremity - walking

    Distribution of maximum force between implanted and non- implanted leg during walking

    pre-operatively

    pre-operatively

  • Force generated by operative extremity - walking up stairs

    Distribution of maximum force between implanted and non- implanted leg during walking up stairs

    6 weeks post-operatively

  • Force generated by operative extremity - walking up stairs

    Distribution of maximum force between implanted and non- implanted leg during walking up stairs

Eligibility Criteria

Age18 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Subjects who have been appropriately designated for treatment with a primary total knee arthroplasty
  • Subjects who are willing to participate and are willing to sign the Informed Consent/HIPPA documents.

You may not qualify if:

  • Subjects who are unsuitable candidates for the two types of knee implants under investigation.
  • Subjects with significant deformities or arthritis that might affect the procedural decision making, expected outcomes and functions are total knee arthroplasty.
  • Subjects with significant comorbidities that might be at an increased risk of post-operative complications.
  • Subjects who are unwilling to sign Informed Consent/HIPAA documents.
  • Subjects who cannot perform the required activities after the surgery.

Masking Details
The patient will be randomized to one of 2 treatment arms using a random number generator. The care provider will not be blinded as he will be implanting the device and following the patients' progress in clinic postoperatively, including radiographs which will show the implants. He will be blinded, however, to the results of the KOOS score and the data derived from the force plate analysis. The research assistants performing those assessments will be blinded to which treatment arm the patient belongs to.
