“…Previous work performed by the authors [51,53] suggested that 25 patients (50 knees) would be required to achieve 90% power to detect a small to moderate effect of tourniquet use on quadriceps strength at 3 weeks postoperatively, the primary variable of this report. Because leg dominance was not formally assessed in this study, it is conceivable that-by chance-the tourniquet could have been applied to the nondominant leg a greater proportion of the time, thus confounding outcomes in favor of the notourniquet group.…”

“…Early postoperative deficits in quadriceps strength may be particularly problematic because there is reason to believe that early strength loss, occurring primarily through deficits in voluntary muscle activation [36], may actually exacerbate long-term weakness [24]. In fact, there is a growing body of research focused on improving TKA rehabilitation specifically to limit early postoperative loss of quadriceps strength [31,53]. Moreover, for patients undergoing TKA, quadriceps strength is one of the most robust predictors of long-term function in tasks such as chair-rise and stairclimbing ability [35,64].…”

“…Therefore, we chose to base our estimate of sample size on our desire to detect a small to medium effect (Cohen's d \ 0.4) on quadriceps strength at our primary endpoint (3 weeks after surgery). Based on our previous work [51,53], we assumed a standard deviation in quadriceps strength of 29.8 Nm at 3 weeks after surgery and estimated that 25 patients (50 knees) would be required to achieve 90% power to detect a small to medium effect (approximately 12 Nm) at this time point. Sample size estimates were performed using Statistical Analysis Software (SAS Institute Inc, Cary, NC, USA).…”

Background Tourniquet use during total knee arthroplasty (TKA) improves visibility and reduces intraoperative blood loss. However, tourniquet use may also have a negative impact on early recovery of muscle strength and lower extremity function after TKA. Questions/purposes The purpose of this study was (1) to determine whether tourniquet use affects recovery of quadriceps strength (primary outcome) during the first 3 postoperative months; and (2) to examine the effects of tourniquet application on secondary outcomes: voluntary quadriceps activation, hamstring strength, unilateral limb balance as well as the effect on operative time and blood loss.Methods Twenty-eight patients (mean age 62 ± 6 years; 16 men) undergoing same-day bilateral TKA (56 lower extremities) were enrolled in a prospective, randomized study. Subjects were randomized to receive a tourniquetassisted knee arthroplasty on one lower extremity while the contralateral limb underwent knee arthroplasty without extended tourniquet use. In the former group, the tourniquet was inflated just before the incision was made and released after cementation; in the latter group, a tourniquet was not used (10 of 28 [36%]) or inflated only during component cementation (18 of 28 [64%]). The choice of no tourniquet or use just during cementation was based on surgeon choice, because some surgeons felt a tourniquet during cementation was necessary to achieve a dry surgical field to maximize cement fixation.

“…All patients were given visual targets from the dynamometer's output and strong verbal encouragement during each trial. Maximal voluntary isometric contractions for all muscle groups were performed twice; however, if maximal torque during the first two trials differed by more than 5%, a third trial was performed, as previously described [18,[46][47][48]. The trial with the highest torque was normalized to body mass (kg) and used for analysis [1].…”

Background Patients undergoing total hip arthroplasty (THA) often are satisfied with the decrease in pain and improvement in function they achieve after surgery. Even so, strength and functional performance deficits persist after recovery, but these remain poorly characterized; knowledge about any ongoing strength or functional deficits may allow therapists to design rehabilitation programs to optimize recovery after THA. Questions/purposes The purposes of this study were to (1) evaluate postoperative muscle strength, function, and quality of life during the first year after THA; and (2) compare strength and function in patients 1 year after THA with a cohort of healthy peers. Methods Twenty-six patients undergoing THA were assessed 1, 3, 6, and 12 months postoperatively, and 19 adults with no hip pathology were tested as a control group. Isometric muscle strength (hip flexors, extensors, abductors, knee extensors, and flexors), functional performance (stair climbing, five times sit-to-stand, timed-up-and-go, 6-minute walk, and single-limb stance tests), and selfreported function (Hip Disability and Osteoarthritis Score, SF-36, and UCLA activity score) were compared. Results One month after THA, patients had 15% less hip flexor and extensor torque, 26% less abductor torque, 14% less knee extensor and flexor torque, and worse performance on the stair climbing, timed-up-and-go, single-limb stance, and 6-minute walk. Compared with healthy adults, patients 12 months after THA had 17% less knee extensor and 23% less knee flexor torque; however, the functional testing (including stair climbing, five times sit-to-stand, and the 6-minute walk) showed no significant differences with the patient numbers available between individuals undergoing THA and healthy control subjects. SF-36 Physical Component Scores, although significantly improved from preoperative levels, were significantly worse than healthy adults 1 year after THA (p \ 0.01).

Early Neuromuscular Electrical Stimulation to Improve Quadriceps Muscle Strength After Total Knee Arthroplasty: A Randomized Controlled Trial

Abstract: The early addition of NMES effectively attenuated loss of quadriceps muscle strength and improved functional performance following TKA. The effects were most pronounced and clinically meaningful within the first month after surgery, but persisted through 1 year after surgery.
