MAKO Total Knee Artroplasty

Active, not recruiting
Conditions
Osteoarthritis, Knee
Interventions
Device: FocusMotion knee brace
Device: Fitbit tracking device
Device: FocusMotion app
Registration Number
NCT05744895
Lead Sponsor
Washington University School of Medicine
Brief Summary

The purpose of this study is to determine the early clinical and radiographic outcomes of robotically assisted total knee arthroplasty with the MAKO surgical robot using the Triathlon knee system. Results of this study will be compared to those of a previously published cohort of patients from this institution who underwent TKA using non-robotic, manual instruments.

MAKO TKA patients will be given Fitbits and the Focus Motion Knee Brace to capture the data listed in attachment section. The results of this data will be compared to the control group to see if there is or there is not a difference in clinical outcomes with patients receiving Total knee surgery using the MAKO surgical robot versus those who got Total knee surgery without the MAKO robot.

Detailed Description

Research objectives:

The purpose of this study is to determine the early clinical and radiographic outcomes of robotically assisted total knee arthroplasty with the MAKO surgical robot using the Triathlon knee system. Mean weekly VAS pain score during the first 4 weeks is the primary end point. Results of this study will be compared to prospective cohort of patients in the IRB study 201805014 from this institution who underwent TKA using non-robotic, manual instruments

Primary Hypothesis: Patients receiving robotic TKA will have better early recovery, including lower mean weekly VAS pain score for the first 4 weeks postoperatively and higher functional outcome scores, than the manual TKA historical cohort.

Secondary Hypothesis:

Patients receiving robotic TKA will have more accurate component position and alignment than the manual TKA historical cohort.

Potential Contribution: This study would give us a better understanding of the clinical and radiographic outcomes of patients receiving robotic TKA versus manual TKA. It will identify potential advantages and disadvantages of robotic TKA using the MAKO surgical robot.

Primary Outcome Measures
NameTimeMethod
Early recovery4 weeks

To determine if Robotic-arm assisted TKA (RA-TKA) allows for earlier recovery than manual TKA (MI-TKA). This will be measured by weekly VAS pain score.

\[Time Frame: 1 day- post op\]

Secondary Outcome Measures
NameTimeMethod
Post op EOS measurements for alignment1 year

To determine if Robotic-arm assisted TKA (RA-TKA) allows for more accurate component placement than manual TKA (MI-TKA). units of measurement will be inches.
