The Effect of Preoperative Exercise on Total Knee Replacement Outcomes

Prehabilitation Before Total Knee Arthroplasty Increases Strength and Function in Older Adults With Severe Osteoarthritis

“…Individuals with knee OA have significantly lower quadriceps strength compared to their nonaffected leg or with healthy age-matched controls (21,24). Various exercise programs designed to improve leg strength and ability to perform functional tasks of individuals before TKA have demonstrated limited success (2,8,27). These investigations assessed functional ability primarily through the measurement of perception and self-report of function (2,8,27).…”

Preoperative Strength Training for Patients Undergoing High Tibial Osteotomy: A Prospective Cohort Study With Historical Controls

“…Previous studies examining preoperative resistance training in patients with knee OA undergoing knee arthroplasty have found limited benefits to postoperative strength, range of motion, selfreport questionnaires, and physical function. 4,15,38 However, the intensity of these programs often did not result in significant changes in strength after the strengthening intervention (ie, prior to the surgery). While Rooks et al 39 did observe significantly increased strength preoperatively after resistance training (20% increased), there were still no significant improvements in outcomes after surgery, when compared to a control group.…”

Rehabilitation and Physical Therapy before and after Total Knee Arthroplasty: A Literature Review and Unanswered Questions

“…The efficacy of preoperative rehabilitation programmes has been clearly related to increased strength of the affected leg, decreased leg strength asymmetry and increased ability in performing functional tasks before TKA. Similarly-and most interestingly-encouraging results have been shown after prehabilitation, in terms of achieving a better quality of life, a faster ROM recovery and shorter time of hospitalisation: also it can improve muscle tropism, which is a positive predictor for postoperative functional recovery [50][51][52][53][54][55][56][57][58][59][60][61]. Neuro muscular electrical stimulation was found to be useful in prehabilitation to expedite a return to normal activities in patients undergoing TKA for knee osteoarthritis.…”

“…The concept of preparing the body for a stressful event, such as surgery, has been named "prehabilitation" [53]. Its efficacy is still under debate: the effects of pre-operative physical therapy and general cardiovascular conditioning exercises on the post-operative functional recovery have been compared with those of no preoperative therapy [54]. Three patient groups were created, each one characterised by different pre-and post-operative protocols; the results showed that, if all groups showed tolerance on their exercise protocols, none showed significant benefits compared with the others.…”
