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.
Findings showed significant differences from baseline scores to scores at 6 weeks following TKA for the PRT group which had better outcomes for the 30-second chair stand test, the TUG, normalized knee extensor muscle strength and normalized knee extensor muscle strength. Investigators noted patient-reported outcomes were not significantly different between patients who underwent intervention and those in the control group.
