Aim To investigate the potential role of a novel electrostimulation device in augmenting the femoral vein venous blood flow following total knee replacement surgery. Material and methods A total of 30 consecutive patients undergoing total knee replacement were allocated to receive either peroneal nerve electrostimulation plus low molecular weight heparin and below-knee compression stockings (Group 1, electrostimulation group, n = 15, mean age: 63.40 ± 5.91 years, male: female ratio 9:6) or low molecular weight heparin and below-knee compression stockings alone (Group 2, control group, n = 15, mean age: 63.86 ± 7.47 years, male: female ratio 8:7). Electrostimulation was performed for 1 h in every 4 h after the operation. Peak blood velocity in the femoral vein was evaluated with Duplex ultrasonongraphy in supine position. Presence of leg edema and calf diameter was also taken into consideration as outcome measures, which were recorded both before surgery and at the time of discharge from hospital. Results Postoperative peak blood flow velocity in the femoral vein was significantly higher in electrostimulation group compared to control group (17.46 ± 2.86 cm/s vs. 13.84 ± 3.58 cm/s, p < 0.02). Electrostimulation group achieved a significant increase in peak blood flow velocity in the femoral vein after the operation (mean increase 67.48 ± 17.38%, p < 0.001). Conclusion Electrostimulation of the common peroneal nerve enhanced venous flow in the lower limb and may potentially be of use as a supplementary technique in deep venous prophylaxis following lower limb orthopedic operations.

A comparative analysis of the dynamics of lower limb vein angioscopy parameters in case of orthostasis between male patients (age 30–50 years) with arterial hypertension (test group – 60 people) and normal arterial pressure (control group – 27 people) was made. Orthostatic sample in all examined patients was characterized by a reliable increase in the diameter and area of vein section at a decrease in blood flow rate. However, in patients with hypertension the increase in the area of vein section was significantly less than in the control group. In orthostasis, the drop in blood flow rate in the total femoral vein was lower in men with hypertension than in men in the control group. In the great saphenous vein, a larger decrease in blood flow velocity was recorded than in the control group. In hypertension, no increase in the number of refluxes was recorded in orthostasis. Thus, hypertension in men is characterized by altered reaction of venous blood flow to orthostasis in both deep and saphenous veins.

Abstract Background During pregnancy, a number of changes affecting venous blood flow occur in the circulatory system, such as reduced vein wall tension or increased exposure to collagen fibers. These factors may cause blood stagnation, swelling of the legs, or endothelial damage and consequently lead to development of venous disease. Objectives The aim of this study is to evaluate the effect of special footwear designed to improve blood circulation in the feet on venous blood flow changes observed during advancing phases of pregnancy. Methods Thirty healthy pregnant women participated in this study at 25, 30, and 35 weeks of gestation. Participants were allocated at random to an experimental group (n = 15) which was provided with the special footwear, or a control group (n = 15). At each data collection session, Doppler measurements of peak systolic blood flow velocity and cross-sectional area of the right popliteal vein were performed using a MySonoU6 ultrasound machine with a linear transducer (Samsung Medison). The differences were compared using Cohen’s d test to calculate effect size. Results With advancing phases of pregnancy, peak systolic velocity in the popliteal vein decreased significantly in the control group, whereas it increased significantly in the experimental group. No significant change in cross-sectional area was observed in any of the groups. Conclusions Findings in the experimental group demonstrated that wearing the footwear tested may prevent venous blood velocity from reducing during advanced phases of pregnancy. Nevertheless, there is a need for further investigation of the beneficial effect on venous flow of the footwear tested and its application.

This study aims to determine the effect of counseling on quality of life and self-care agency for patients who are scheduled for total knee replacement (TKR). The study has a quantitative and quasi-experimental design with a control group. The patients in the control group ( n = 40) received routine care. Face-to-face and telephone counseling was offered to individuals in the intervention group ( n = 39). The data was collected at face-to-face interviews by using a patient characteristics form, Quality of Life Scale, and Self-Care Agency Scale. The scores for quality of life and self-care agency in the 6th to 8th and 14th to 16th weeks after surgery were very significantly higher in the intervention group than in the control group ( p < .001). This study shows that counseling given by the nurse increases the quality of life and self-care agency of patients undergoing TKR.

Background and Aims: Obesity is an increasing problem in patients after total knee replacement. The aim of this study was to investigate whether a weight loss intervention before primary total knee replacement would improve quality of life, knee function, mobility, and body composition 1 year after surgery. Material and Methods: Patients scheduled for total knee replacement due to osteoarthritis of the knee and obesity were randomized to a control group receiving standard care or to an intervention group receiving 8-week low-energy diet before total knee replacement. Patient-reported quality of life, 6-Min Walk Test, and body composition by dual-energy X-ray absorptiometry were assessed before intervention for the diet group, and within 1 week preoperatively for both groups, and the changes in outcome from baseline to 1 year after total knee replacement were compared between groups. The number of participants was lower than planned, which might introduce a type-2 error and underestimate the trend for a better outcome after weight loss. Results: The analyses are based on a total of 76 patients, 38 in each group. This study showed major improvement in both study groups in quality of life and knee function, though no statistically significant differences between the groups were observed 1 year after total knee replacement. The average weight loss after 8-week preoperative intervention was 10.7 kg and consisted of a 6.7 kg reduction in fat mass. One year after total knee replacement, the participants in the diet group managed to maintain the weight reduction, whereas there was no change in the control group. Conclusion: The results suggest that it is feasible and safe to implement an intensive weight loss program shortly before total knee replacement. The preoperative intervention resulted in a 10% body weight loss, improved body composition, lower cardiovascular risk factors, and sustained s-leptin.

Our aim was to measure the venous blood flow velocity (VBFV) in case of hemiparetic patients, after passive and active thromboembolic methods, as well as the consensual effect in the hemiparetic limb following the active venous exercises in the healthy limb. We examined 215 patients, with the median age of 58.0 (55.0-63.0) years. The VBFV was measured with a HADECO BIDOP ES-100 V II type Doppler ultrasound device, using an 8 MHz head, on the femoral vein at the level of the hip joint. For statistical analysis, SPSS version 22 was used. After passive movement, on the hemiparetic side, compared to the value in resting state, the VBFV significantly (12.6; 11.6-13.5 cm/s; P < .001) increased. Following active venous exercises performed on the healthy side, the VBFV significantly (18.0; 15.6-19.6 cm/s; P < .001) increased compared to the value in resting state. Following the active venous exercises performed on the healthy side, the VBFV measured on the hemiparetic side (consensual effect) was significantly (15.1 [14.1-16.5] cm/s; P < .001) higher than the value on the hemiparetic side in resting state. Active and passive mechanical thromboprophylaxis methods can be effective. Movements of the healthy limb significantly increase the VBFV in the inactive limb, and patients can perform it themselves several times a day.

Background: Recently, new methods have emerged that encourage voluntary participation by allowing patients to perform tasks, including exercises or treatments, in a virtual reality (VR) environment. Aim: This study aimed to examine the effects of full immersion virtual reality training on balance and knee function in patients who had undergone total knee replacement. Design: Single blind randomized controlled trial. Setting: Department of Physical Therapy in a rehabilitation center. Population: A total of 30 elderly patients ([Formula: see text]65 years old) who had undergone total knee replacement. Methods: Participants were randomly allocated to an experimental group ([Formula: see text]) and a control group ([Formula: see text]). The experimental group received with a continuous passive motion machine, exercise therapy, and a full immersion VR training program; the control group received only with a continuous passive motion machine and exercise therapy. Biorescue was used to test static and dynamic balance ability, and the Timed Up and Go and Western Ontario and McMaster Universities tests were used to assess knee function. Paired [Formula: see text]-tests were used to examine differences by time in each group, and independent [Formula: see text]-tests were used to examine differences between the groups. Results: In terms of within-group differences by time, both the experimental group and the control group showed significant changes in the anterior, and posterior limits of stability in both sides; static balance; and knee function. In the between-groups comparison, among static balance tests, there was a significant difference in center of mass path length in the standing position with eyes open ([Formula: see text]); among dynamic balance tests, there were significant differences in left, right, anterior, and posterior limits of stability ([Formula: see text]). Conclusions: VR training produced better early balance ability and knee function than what was seen in the control group. We believe that VR training in initial post-operative rehabilitation of total knee replacement patients may increase the rate of recovery. Clinical Rehabilitation Impact: VR exercise programs are effective in early rehabilitation after total knee replacement, and have clinical value as inexpensive methods that can promote active participation.

(1) Background: Knee osteoarthritis (KOA) and aging are associated with high sarcopenia risk; sarcopenia may further affect outcomes after total knee replacement (TKR). Elastic resistance exercise training (RET) limits muscle attenuation in older adults. We aimed to identify the effects of post-TKR elastic RET on lean mass (LM) and functional outcomes in overweight and obese older women with KOA by using the brief International Classification of Functioning, Disability and Health Core Set for osteoarthritis (Brief-ICF-OA). (2) Methods: Eligible women aged ≥60 years who had received unilateral primary TKR were randomly divided into an experimental group (EG), which received postoperative RET twice weekly for 12 weeks, and a control group (CG), which received standard care. The primary and secondary outcome measures were LM and physical capacity, respectively, and were linked to the Brief-ICF-OA. The assessment time points were 2 weeks prior to surgery (T0) and postoperative at 1 month (T1; before RET) and 4 months (T2; upon completion of RET) of follow-up. An independent t test with an intention-to-treat analysis was conducted to determine the between-group differences in changes of outcome measures at T1 and T2 from T0. (3) Results: Forty patients (age: 70.9 ± 7.3 years) were randomly assigned to the EG (n = 20) or CG (n = 20). At T2, the EG exhibited significantly greater improvements in leg LM (mean difference (MD) = 0.86 kg, p = 0.004) and gait speed (MD = 0.26 m/s, p = 0.005) compared with the CG. Furthermore, the EG generally obtained significantly higher odds ratios than the CG for treatment success for most Brief-ICF-OA categories (all p < 0.001). Conclusions: Early intervention of elastic RET after TKR yielded positive postoperative outcomes based on the Brief-ICF-OA. The findings of this study may facilitate clinical decision-making regarding the optimal post-TKR rehabilitation strategy for older women with KOA.

Objective: To assess the effects of preoperative balance training on the early postoperative balance and functional outcomes after total knee replacement surgery and to test whether an outpatient intervention may be as effective as a domiciliary intervention. Design: This is a three-arm randomized controlled trial. Setting: University hospital. Subjects: Eighty-six individuals were recruited. Seventy-seven were analysed, aged 72.1 (SD 7.6) years, of which 68% were women. Outcome measures: Overall state of balance, as measured with the Berg Balance Scale, and patient-perceived functionality, as measured with the Knee Injury and Osteoarthritis Outcome Score Function in Activities in Daily Living (KOOS-ADL) questionnaire, were the primary outcomes. Secondary assessments targeted knee function, balance and mobility, quality of life, and self-reported outcomes. The primary end-point was six weeks after surgery. Intervention: The hospital group implemented a four-week preoperative outpatient balance-oriented intervention. The home group implemented similar training, but this was domiciliary. The control group was instructed to keep performing their normal activities. Results: Home and hospital groups presented a moderate effect against the control group ( dhospital-control = 0.54; dhome-control = 0.63), both being similarly effective in improving the overall state of balance at six weeks after surgery ( P = 0.013). KOOS-ADL scores showed no between-group differences and a small effect size ( d < 0.5; P = 0.937). Secondary assessments suggested non-significant between-group differences. Conclusion: Preoperative balance training, conducted either as domiciliary or as an outpatient, is an effective approach to enhance early postoperative balance outcome but not the perceived functionality of individuals undergoing total knee replacement.

Surgeries for total knee replacement (TKR) are increasing and in this context there is a need to develop new protocols for management and use of blood transfusion therapy. Autologous blood reduces the need for allogeneic blood transfusion and the aim of the present study was to verify the safety and the clinical efficacy. An observational retrospective study has been conducted on 124 patients, undergoing cemented total knee prosthesis replacement. Observed population was stratified into two groups: the first group received reinfusion of autologous blood collected in the postoperative surgery and the second group did not receive autologous blood reinfusion. Analysis of data shows that patients undergoing autologous blood reinfusion received less homologous blood bags (10.6% versus 30%; p=0.08) and reduced days of hospitalization (7.88 ± 0.7 days versus 8.96 ± 2.47 days for the control group; p=0.03). Microbiological tests were negative in all postoperatively salvaged and reinfused units. Our results emphasize the effectiveness of this procedure and have the characteristics of simplicity, low cost (€97.53 versus €103.79; p<0.01), and easy reproducibility. Use of autologous drainage system postoperatively is a procedure that allows reducing transfusion of homologous blood bags in patients undergoing TKR.
