NCT02265523

Brief Summary

The purpose of this investigation is to examine the effect of, and improve patient compliance and motivation following total knee arthroplasty; to determine the efficacy of two post-surgical exercise programs on knee pain, function, range of motion, strength, and swelling (girth); and to establish a panel of biomarkers that will allow: a) early identification of patients at risk (i.e. unable to complete post-operative treatment) and; b) predict the likelihood of a successful treatment outcome post-surgically.

Outcome Measures

Primary Outcomes (2)

  • Knee pain/functional status/swelling/ROM/strength

    Knee pain will be measured using the visual analog scale (VAS), and functional status will be measured using the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC). Knee swelling will be measured via girth measures taken 15 cm superior to the superior pole of the patella; at the supra and infrapatellar regions; and 15 cm inferior to the inferior pole of patella, and flexion and extension ROM will be measured in degrees using a goniometer. The mean of three trials of resisted isometric knee flexor and extensor strength will be measured in lbs of force using a Lafayette Manual Muscle Tester.

    All will be measured pre-operatively (baseline measure), and at day 2 post-operatively, upon discharge (anywhere from day 5-14 post-operatively), and 12 weeks post-operatively to observe changes from the baseline measure.

  • Blood markers of inflammation/nutritional status/thrombogenesis risk

    Plasma and serum will be isolated from whole blood samples and various assays will be completed to detect markers indicative of inflammation, poor nutritional status, and increased risk of thromboembolic events.

    All will be measured pre-operatively (baseline measure), at day 2 post-operatively, and upon discharge (anywhere from day 5-14 post-operatively) to observe changes from the baseline measure.

Secondary Outcomes (2)

  • Participant motivation.

    Questionnaire will be completed pre-operatively, at day 2 post-operatively, upon discharge (anywhere from 5-14 days post-operatively), and 12 weeks post-operatively.

  • Patient compliance.

    Questionnaire will be completed pre-operatively, at day 2 post-operatively, upon discharge (anywhere from 5-14 days post-operatively), and 12 weeks post-operatively.

Other Outcomes (1)

  • Adverse events.

    Will be completed from pre-operative to 12 weeks post-operatively as they arise.

Study Arms (2)

Standard Post-op Exercise Group

NO INTERVENTION

The standard post-operative exercises are already currently recommended to patients. Briefly, they include deep breathing and coughing, ankle pumping, buttock contractions, and static quadriceps strengthening. These are performed on a daily basis , 2-3 times per day, 30 repetitions.

Viscus Group

EXPERIMENTAL

The Viscus (intervention) group will complete the standard post-operative exercises and will also have access to a Viscus V1.5 cycle ergometer 24 hours per day in their recovery room to use at their leisure.

Other: Cycle ergometer

Interventions

The Viscus V1.5 is a kinetic flywheel cycle ergometer that will allow participants' pedal revolutions to be tracked as well as time of use.
