Effect of Pre-Surgery Strength Training on Function and Satisfaction After Total Knee Replacement in Adults Aged 50 to 80

What this Trial Is About

Knee osteoarthritis is a common condition often treated first with non-surgical methods such as exercise. Despite advances in surgery, about 20% of patients who undergo total knee replacement remain dissatisfied with their results. This trial aims to see if doing strength training before surgery can improve leg strength and reduce dissatisfaction after the operation. Participants will be randomly assigned to one of two groups one group will do maximal leg press strength training three times a week at about 85% of their maximum effort for eight weeks before surgery, and the other will receive usual care without the added training. This setup allows researchers to compare the effects of pre-surgery strength training against standard treatment. Throughout the study, leg strength will be measured at multiple points including before surgery, one week before surgery, three weeks after surgery, and up to 12 months post-surgery. The study will also assess patient satisfaction after surgery, along with voluntary muscle activation, knee function, walking speed, chair rising ability, and balance. These evaluations will help determine if pre-surgery training improves recovery and satisfaction over time.
