About the trial

What the trial wants to find out

The primary aim of this study is to investigate the efficacy of 8 weeks of Low-load blood flow restricted exercise (BFRE) compared to receiving standard care only (no preoperative training) before total knee replacement (TKR) on postoperative 30-seconds chair stand test (30s-CST). We hypothesize that 8 weeks of preoperative BFRE will increase chair stand performance 3 months postoperatively. Secondary aims are to investigate the efficacy of 8 weeks of preoperative BFRE compared to receiving standard care only on changes in muscle strength 3 months after TKR and investigate associations to functional capacity and quality of life. Furthermore, it will be investigated if 8 weeks of BFRE induces muscle hypertrophy and increases satellite cell and myonuclei content of the vastus lateralis muscle.

The 2 groups in the trial

  • Group 1 (BFRE)Treatment being tested

    Low-load blood flow restricted exercise 3/weekly for 8 weeks before TKR 10-min warm-up followed by unilateral leg press and unilateral knee extension

    Treatment: Low-load blood flow restricted exercise

  • Group 2 (CON)No study treatment, for comparison

    No training before TKR
