About this study

Official title: Investigation of the Effect of Foam Rolling After Total Knee Arthroplasty on Pain, Range of Motion, Muscle Strength, Proprioception, Kinesiophobia, Gait, Balance, and Functional Level

The aim of this study is to investigate the effects of foam rolling in patients who have undergone total knee arthroplasty on pain, knee mobility, leg muscle strength, the ability to sense joint position, fear of movement, walking, balance, and the ability to perform daily activities.

A total of 26 patients, with 13 patients in each group, will be included in the study. Participants will be randomly assigned to two groups. One group will receive the routine rehabilitation program, while the other group will receive foam rolling in addition to the routine rehabilitation program.

Foam rolling and rehabilitation exercises will be taught at the Dokuz Eylül University Orthopedics and Traumatology Outpatient Clinic, and you will be asked to perform these exercises at home. The foam rolling group will perform foam rolling 6 days per week, 2 sets per day, with 3 repetitions of 60 seconds each. The control group will not perform foam rolling and will follow the routine rehabilitation program.

The standard rehabilitation program will consist of strengthening exercises in different directions for the entire leg, range-of-motion exercises, stretching exercises, and walking exercises. You will be asked to perform the exercises for 3 sets of 10 repetitions per day.

The assessments in the study will be performed at the second postoperative week (test 1), sixth postoperative week (test 2), and fourteenth postoperative week (test 3). These time points are also times when you would normally visit your doctor for routine follow-up; therefore, you will not be expected to make any additional hospital visits for the study.

The study will continue for 1 year, and each patient will be followed for 14 weeks.

Pain will be assessed using a single-question questionnaire. Walking, functional level, and leg muscle strength will be assessed using short performance tests involving sitting-to-standing and walking activities, as well as a questionnaire. Knee joint range of motion and proprioception will be assessed by measuring the angles of your knee using a ruler-like plastic device. Fear of movement will be assessed using a short questionnaire.

All assessments will take no more than 20 minutes. The results will be determined by examining whether there are differences in these measurements between the different assessment time points.

Read the detailed description

The aim of this study is to investigate the effects of foam rolling after total knee arthroplasty on pain, range of motion, muscle strength, proprioception, kinesiophobia, gait, balance, and functional level.

All patients will receive education regarding postoperative pain management, exercises, foam rolling, and the rehabilitation program to be implemented. Both the rehabilitation exercises and foam rolling will be taught to the patients by physiotherapists in the outpatient clinic and performed by the patients at home as part of their home program. The foam rolling intervention group will perform foam rolling for 4 weeks starting from the second postoperative week, 3 days per week, 1 set per day, with 3 repetitions of 60 seconds each. The control group will not perform foam rolling and will follow the standard home exercise program.

The standard home exercise program will consist of lower-extremity range-of-motion exercises, isometric exercises, stretching exercises for the knee joint, and straight leg raise exercises in different directions. Patients will be instructed to perform these exercises for 3 sets of 10 repetitions per day. In addition, patients will be encouraged to mobilize both indoors and outdoors.

Outcome assessments will be performed at the second postoperative week (test 1), sixth postoperative week (test 2), and fourteenth postoperative week (test 3).

Demographic and clinical characteristics, including age, gender, height, body weight, and body mass index, will be recorded on the data collection form. Clinical assessments will include pain level, range of motion, muscle strength, proprioception, kinesiophobia, gait, balance, and functional level. Maximum isometric muscle strength will be assessed only at the fourteenth postoperative week (test 3).

Pain will be assessed using the Visual Analog Scale (VAS). The maximum isometric muscle strength of the quadriceps femoris and hamstring muscles will be assessed using manual muscle testing and a hand-held dynamometer. Range of motion will be assessed using a plastic manual goniometer. Knee joint proprioception will be assessed using the active joint repositioning test at target angles of 30° and 60° of knee flexion. The Hospital for Special Surgery (HSS) Knee Score will be used to evaluate knee arthroplasty outcomes. Kinesiophobia will be assessed using the self-reported Tampa Scale for Kinesiophobia. The Timed Up and Go Test and the Five-Times Sit-to-Stand Test will be used to assess lower-extremity function, functional mobility, gait, and balance.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Foam rolling after total knee arthroplastyOther

    The foam rolling intervention will be performed for 4 weeks starting from the second postoperative week, 3 days per week, 1 set per day, with 3 repetitions of 60 seconds each.

  • Standard home exercise program after total knee arthroplastyOther

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Change from baseline at week 14 in knee pain

    Pain will be assessed using the 10-cm Visual Analog Scale (VAS), scored from 0 (no pain) to 10 (unbearable pain).

    Measured: From enrollment to the end of the 14-week period

  2. Change from baseline at week 14 in knee range of motion

    Knee range of motion will be measured using a 30-cm transparent plastic manual goniometer.

    Measured: From enrollment to the end of the 14-week period

Secondary outcomes (6)
  1. Change from baseline at week 14 in muscle strength

    Maximum isometric strength of the quadriceps femoris and hamstring muscles will be measured using a hand-held dynamometer and muscle strength will also be assessed using manual muscle testing.

    Measured: From enrollment to the end of the 14-week period

  2. Change from baseline at week 14 in knee joint proprioception

    Knee proprioception will be assessed using the active joint repositioning test at 30° and 60° knee flexion, with the absolute difference between the target and reproduced angles recorded.

    Measured: From enrollment to the end of the 14-week period

  3. Change from baseline at week 14 in kinesiophobia

    Kinesiophobia will be assessed using the 17-item Turkish version of the Tampa Scale for Kinesiophobia. Each item will be scored using a 4-point Likert scale ranging from 1 to 4.

    Measured: From enrollment to the end of the 14-week period

  4. Change from baseline at week 14 in Timed Up and Go Test performance

    Gait, balance, and functional mobility will be assessed using the Timed Up and Go Test. The patient will be asked to stand up from a chair, walk 3 meters, turn around, and sit back down. The completion time will be recorded in seconds.

    Measured: From enrollment to the end of the 14-week period

  5. Change from baseline at week 14 in Five Times Sit-to-Stand Test performance

    Lower-extremity strength, balance, and functional level will be assessed using the Five Times Sit-to-Stand Test. The patient will be asked to stand up and sit down five times as quickly and safely as possible, and the completion time will be recorded in seconds.

    Measured: From enrollment to the end of the 14-week period

  6. Change from baseline at week 14 in Hospital for Special Surgery Knee Score

    Knee function will be assessed using the Hospital for Special Surgery Knee Score. The Hospital for Special Surgery (HSS) Knee Score will be rated on a 0-100-point scale, with scores of ≥85 indicating excellent, 70-84 good, 60-69 moderate, and ≤59 poor knee function.

    Measured: From enrollment to the end of the 14-week period
