Results from this study demonstrated the efficacy and safety of preoperative progressive resistance training for postoperative, objective functional performance and muscle strength improvements in patients who underwent total knee arthroplasty for osteoarthritis.
Researchers performed an assessor-blinded, clinical, randomized controlled trial of 59 patients who were diagnosed with osteoarthritis and scheduled to undergo a unilateral total knee arthroplasty (TKA). Patients were assigned to either a preoperative progressive resistance training (PRT) group or to a control group. Following TKA, all patients underwent PRT. Investigators collected outcome measures at 1 week and 6 weeks preoperatively and at 1 week, 6 weeks and 12 weeks postoperatively which included the 30-second chair stand test, timed up-and-go (TUG), walking tests, knee extensor and flexor muscle strength, and health-related quality of life and pain scores using the KOOS.
