Functional Recovery After Total Knee Arthroplasty

This observational study aims to understand how people recover after total knee replacement surgery (total knee arthroplasty or TKA). Researchers are comparing recovery between those who have robotic-assisted TKA and those who have manual TKA (without robotic assistance). They also want to see if there are differences in recovery for revision surgeries (when a previous knee replacement needs to be redone). The study will look at how well you can move and your own feelings about your recovery. You might be able to join if you are between 40 and 90 years old, are a candidate for TKA, and can speak English and understand study instructions. Success in this study means understanding if one type of surgery leads to better or faster functional recovery. The current recruitment status is unclear.

Study design
This is an observational study with a planned enrollment of 30 participants. It compares recovery after robotic-assisted versus manual total knee arthroplasty.
What's involved
You will answer questionnaires and undergo physical therapy tests before your surgery and at 2 weeks, 6 weeks, 3 months, 6 months, and 1 year after surgery.
Compensation
Not stated in the trial record.
Follow-up
Participants will be followed for 1 year after their surgery.

What this trial measures

  • Timed Up and Go (TUG)anytime pre-operatively (baseline) and 2 weeks, 6 weeks, 3 months, 6 months, and 1 year post surgery

    TUG requires the patient to sit in a chair, stand, walk to a line 3m away, turn, walk back to the chair, and sit again

  • 4m and 10m Walking Speed Testanytime pre-operatively (baseline) and 2 weeks, 6 weeks, 3 months, 6 months, and 1 year post surgery
  • 2-minute Walkanytime pre-operatively (baseline) and 2 weeks, 6 weeks, 3 months, 6 months, and 1 year post surgery
  • Stair Climb Testanytime pre-operatively (baseline) and 2 weeks, 6 weeks, 3 months, 6 months, and 1 year post surgery
  • Y Balance Testanytime pre-operatively (baseline) and 2 weeks, 6 weeks, 3 months, 6 months, and 1 year post surgery

    The YBT requires the person to balance on one leg whilst simultaneously reaching as far as possible with the other leg in three separate directions: anterior, posterolateral, and posteromedial
