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

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.

Who can participate

Healthy volunteers accepted: No

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

age 55 +, living in or near the city of Oslo (up to appox 2 hours commute), sceduled for primary knee arthroplasty, able to walk independently with or without walking aids, understand and speak Norwegian sufficently to take instructions and respond to questionnaires

Exclusion criteria

Other reasons than osteoarthritis for knee arthroplasty, revision due to infection or failure, arthroplasty in the same or other limb during the 12 months time period, severe neurological or ohter types of disease that affects walking (e.g MS; parkinsonism, hemiplegiea)

Treatment and study plan

Physical function

Other

Observe walking speed, both maximal and self-selected, over a 12-months period after knee arthroplasty

Primary outcomes

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

    Time frame: Baseline, 3 months and 12 months after surgery

    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.

Secondary outcomes

  1. Sit-to-stand

    Time frame: Baseline, 3 months and 12 months after surgery

    Lower extremity strength will be measured by 30 sec sit to stand. Number of standing up in 30 seconds will be counted and recorded

  2. One legged stance

    Time frame: Baseline, 3 months and 12 months after surgery

    Balance will be measured by one legged stance. The participant will perform the test by standing on one leg and the other in 90 degrees flexion of the hip and knee, hands on hips. The test will be performed twice, with the non-affected leg to be tested first. The best of the two scores for each leg will be recorded.

  3. Knee specific function and pain

    Time frame: Baseline and 12 months

    Pain and function in the knee will be measured by the patient reported form KOOS which includes 42 questions evaluating pain and function in different activities in daily life the last week.

  4. EQ5D- Health-related quality of life

    Time frame: Baseline and 12 months after surgery

    Measures self-reported health-related quality of life.

Other outcomes

  1. Physical activity

    Time frame: Baseline and 12 months after surgery

    To measure physical activity UCLA activity score will be applied. UCLA is a simple scale from 1 to 10 where the participant mark the level that suits their level of activity best. 1 is the lowest, 10 the highest score.
