Maximal and Self-selected Walkingspeed After Knee Arthroplasty - a Prospective Cohort Study

NCT06847113 | Recruiting

• 1 other identifier: 764176
• Study Type: observational
• Target: 130
• Locations: 1 country
• Sites: 1

Brief Summary

The purpose of this prospective study is to explore whether maximal and self-selected walking speed in individuals with knee arthroplasty is a useful and applicable clinical measure that can provide new insights into physical function after prosthetic surgery. We will examine the progression of walking speed and other measures of physical function, and investigate if walking speed can predict postoperative function. Individuals over 55 years, scheduled for knee arthroplasty will be invited to participate. Standardized functional tests such as walking speed, sit to stand and one legged stance along with patient reported outcomes will be assessed preoperatively, three months and 12 months after surgery. The study may provide useful knowledge that can be aplied clinically in the assessment and follow-up of this patient group.

Conditions

Knee Arthroplasty, Total

Outcome Measures

Primary Outcomes (1)

• Change from baseline to 3 and 12 months in means in maximal and self-selected walking speed walikgn

  Walking speed will be measured by 10 meter self-selected and maximal walking speed, respectively. Participant will perform two repetitions of self-selected walking speed, followed by two repetitions of maximal walking speed. Mean, measured by meters per seconds, will be calculated onboth of the two different walking speeds.

  Baseline, 3 months and 12 months after surgery

Secondary Outcomes (4)

• Sit-to-stand

  Baseline, 3 months and 12 months after surgery

• One legged stance

  Baseline, 3 months and 12 months after surgery

• Knee specific function and pain

  Baseline and 12 months

• EQ5D- Health-related quality of life

  Baseline and 12 months after surgery

Other Outcomes (1)

• Physical activity

  Baseline and 12 months after surgery
