Early Rehabilitation After Total Hip Replacement

The purpose of this study is to determine whether supervised progressive resistance training is effective in the early phase after Total Hip Replacement. The investigators hypothesise that 10 weeks of supervised, progressive resistance training immediately after discharge will lead to increased functional performance, muscle strength and muscle power compared to standard rehabilitation consisting of home-based exercise.

About this study

After total hip replacement (THR) surgery there is a documented deficit in muscle strength and functional performance. There is a lack of evidence concerning the effectiveness of postoperative physiotherapy and training, however a few small studies have shown promising effect of resistance training.

The present study will provide new and important knowledge concerning the effect of different rehabilitation strategies after THR. This might lead to a change in the rehabilitation regimes and faster and better recovery after THR surgery.

Who can participate

Healthy volunteers accepted: No

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

Inclusion criteria

  • Total hip replacement for osteoarthrosis
  • Living within 30 km from the hospital
  • Motivated to attend training 2 times/week in 10 weeks
  • Reduced functional ability measured as: HOOS score < 67
  • written informed consent

Exclusion criteria

  • Comorbidities such as cancer, neuromuscular diseases, heart diseases etc.
  • Cognitive impairment
  • Body mass index > 35
  • Resurfacing prosthesis
  • Scheduled additional prosthetic surgery in lower extremity within 6 months

Treatment and study plan

Supervised progressive resistance training

Other

Resistance training 2 times/week initiated within the first week after total hip replacement. The training is supervised by physiotherapists and individually progressed.

Control Group

Other

Standard rehabilitation consisting of home-based exercises with 2 postoperative instructions by a physiotherapist.

Primary outcomes

  1. Leg extension power

    Time frame: 10 weeks postoperative

    The power in leg extension is measured using the Nottingham leg extension power rig. Data is provided in watt and adjusted for bodyweight (watt/kg)

Secondary outcomes

  1. Walking speed

    Time frame: 4 weeks postoperative

    Maximal walking speed measured over 20 m.

  2. Sit-to-stand

    Time frame: 10 weeks postoperative

    The maximal number of rises from a chair within 30 seconds

  3. Stair test

    Time frame: 10 weeks postoperative

    The time taken to ascend 18 steps as fast as possible

  4. Hip Osteoarthritis Outcome Score (HOOS)

    Time frame: 6 months postoperative

    Questionnaire. A disease-specific patient reported outcome measure of function, pain, sport/recreation and quality of life related to the hip.

  5. Walking speed

    Time frame: 10 weeks

    Maximal walking speed measured over 20 m.

  6. Walking speed

    Time frame: 6 months postoperative

    Maximal walking speed measured over 20 m.

  7. Leg extension power

    Time frame: 6 months postoperative

    The power in leg extension is measured using the Nottingham leg extension power rig. Data is provided in watt and adjusted for bodyweight (watt/kg)

  8. Sit-to-stand

    Time frame: 6 months postoperative

    The maximal number of rises from a chair within 30 seconds

  9. Stair test

    Time frame: 6 months postoperative

    The time taken to ascend 18 steps as fast as possible

  10. Hip Osteoarthritis Outcome Score (HOOS)

    Time frame: 2 weeks postoperative

    Questionnaire. A disease-specific patient reported outcome measure of function, pain, sport/recreation and quality of life related to the hip.

  11. Hip Osteoarthritis Outcome Score (HOOS)

    Time frame: 4 weeks postoperative

    Questionnaire. A disease-specific patient reported outcome measure of function, pain, sport/recreation and quality of life related to the hip.

  12. Hip Osteoarthritis Outcome Score (HOOS)

    Time frame: 6 weeks postoperative

    Questionnaire. A disease-specific patient reported outcome measure of function, pain, sport/recreation and quality of life related to the hip.

  13. Isometric muscle strength

    Time frame: 4 weeks postoperative

    Test of isometric muscle strength in hip abduction and hip flexion using hand-held dynamometry

  14. Isometric muscle strength

    Time frame: 10 weeks postoperative

    Test of isometric muscle strength in hip abduction and hip flexion using hand-held dynamometry

  15. Isometric muscle strength

    Time frame: 6 months postoperative

    Test of isometric muscle strength in hip abduction and hip flexion using hand-held dynamometry

  16. Gait quality

    Time frame: 10 weeks postoperative

    Instrumented gait analysis using a combined accelerometer and gyro-sensor in 20 meter walk test and stair climb test. The purpose is to measure asymmetry between limps during walking and stair climbing and compare the two groups according to these variables. This outcome measure is performed on a subgroup of participants (n=26, 13 in each group)

  17. Gait quality

    Time frame: 6 months postoperative

    Instrumented gait analysis using a combined accelerometer and gyro-sensor in 20 meter walk test and stair climb test. The purpose is to measure asymmetry between limps during walking and stair climbing and compare the two groups according to these variables. This outcome measure is performed on a subgroup of participants (n=26, 13 in each group)

  18. Hip Osteoarthritis Outcome Score (HOOS)

    Time frame: 10 weeks postoperative

    Questionnaire. A disease-specific patient reported outcome measure of function, pain, sport/recreation and quality of life related to the hip.

  19. Hip Osteoarthritis Outcome Score (HOOS)

    Time frame: 1 year postoperative

    Questionnaire. A disease-specific patient reported outcome measure of function, pain, sport/recreation and quality of life related to the hip.
