NCT04240769

Brief Summary

The goal of this study is to utilize physical activity monitoring to determine the trajectory of normal recovery as it relates to a patient's ability to get up and get moving. From this work, we hope to be able to define the range in patients' physical activity following knee replacement surgery, and thus, give clinicians a tool and the methodology to identify patients whose recovery is not progressing as quickly as expected. Data from physical activity monitors will allow the research team to identify how active patients are, how vigorous that activity is, and how well that activity correlates with standard and commonly used patient questionnaires.

Outcome Measures

Primary Outcomes (1)

  • Change in physical activity

    The primary outcome measure will physical activity, as extracted from analysis of raw accelerometer data from the activity monitor. Several variables will be extracted from the raw data, including average acceleration vector (Euclidean norm minus one), bouts of physical activity and percentage of active and sedentary time.

    Physical activity will be evaluated for 7 days at approximately 2 weeks before surgery, for 6 continuous weeks immediately postoperatively and (for a subset of participants) for 7 continuous days at 6 months postoperatively.

Secondary Outcomes (4)

  • Change in Oxford Knee Score

    Pre-operative (baseline), 6 weeks, 6 months

  • Change in EQ-5D-5L

    Pre-operative (baseline), 6 weeks, 6 months

  • Change in University of California, Los Angeles (UCLA) Activity Score

    Pre-operative (baseline), 6 weeks, 6 months

  • Change in International Physical Activity Questionnaire Questionnaire - Short Form

    Pre-operative (baseline), 6 weeks, 6 months

Study Arms (1)

Knee Arthroplasty Patient

Patients undergoing primary total or unicompartmental knee arthroplasty for treatment of end-stage osteoarthritis.

Device: Total or Partial Knee Arthroplasty

Interventions

Reconstruction of part or all of the native articulation at the knee joint via implant.

Also known as: Knee Replacement
Knee Arthroplasty Patient

Eligibility Criteria

Age18 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)
Sampling MethodNon-Probability Sample
Study Population

Participants will be patients undergoing primary total or unicompartmental knee arthroplasty for treatment of end-stage osteoarthritis.

You may qualify if:

  • Participant is willing and able to give informed consent for participation in the study.
  • Male or Female, aged 18 years or above.
  • Diagnosed with required late stage osteoarthritis, undergoing knee arthroplasty in the next 3 months.
  • In Investigator's opinion, is able and willing to comply with all trial requirements.

You may not qualify if:

  • Any other significant disease or disorder which, in the opinion of the Investigator, may either put the participants at risk because of participation in the study, or may influence the result of the study, or the participant's ability to participate in the study.
  • Participants who are enrolled in another research study involving an investigational product or methodology that could alter physical activity.
  • Participants are undergoing a revision arthroplasty surgery on the operative knee
