Aims Many surgeons choose to perform total knee arthroplasty (TKA) surgery with the aid of a tourniquet. A tourniquet is a device that fits around the leg and restricts blood flow to the limb. There is a need to understand whether tourniquets are safe, and if they benefit, or harm, patients. The aim of this study was to determine the benefits and harms of tourniquet use in TKA surgery. Methods We searched MEDLINE, EMBASE, Cochrane Central Register of Controlled trials, and trial registries up to 26 March 2020. We included randomized controlled trials (RCTs), comparing TKA with a tourniquet versus without a tourniquet. Outcomes included: pain, function, serious adverse events (SAEs), blood loss, implant stability, duration of surgery, and length of hospital stay. Results We included 41 RCTs with 2,819 participants. SAEs were significantly more common in the tourniquet group (53/901 vs 26/898, tourniquet vs no tourniquet respectively) (risk ratio 1.73 (95% confidence interval (CI) 1.10 to 2.73). The mean pain score on the first postoperative day was 1.25 points higher (95% CI 0.32 to 2.19) in the tourniquet group. Overall blood loss did not differ between groups (mean difference 8.61 ml; 95% CI -83.76 to 100.97). The mean length of hospital stay was 0.34 days longer in the group that had surgery with a tourniquet (95% CI 0.03 to 0.64) and the mean duration of surgery was 3.7 minutes shorter (95% CI -5.53 to -1.87). Conclusion TKA with a tourniquet is associated with an increased risk of SAEs, pain, and a marginally longer hospital stay. The only finding in favour of tourniquet use was a shorter time in theatre. The results make it difficult to justify the routine use of a tourniquet in TKA surgery.

AbstractThe study aimed to investigate the effects of postoperative position of knee on blood loss and functional recovery after total knee arthroplasty (TKA). We enrolled patients who underwent TKA from 2017 to 2019 in our department with osteoarthritis of the knee in this prospective and randomized study. The patients were randomly allocated to flexion or extension group. In the flexion group, the affected leg was elevated by 30 degrees at the hip and the knee was flexed by 30-degree, postoperatively, while in the extension group, the affected knee was fully extended postoperatively. Patients' data related to postoperative blood loss, Hospital for Special Surgery scores, pain intensity, usage of analgesic drugs, circumference of knee, and range of motion (ROM) of knee were recorded to assess the influence of postoperative leg position on clinical outcomes. Although the transfusion rate was similar between the two groups (p > 0.05), other parameters related to blood loss (including total blood loss, hidden blood loss, usage of analgesic drugs, and postoperative circumference of knee) were significantly lower in the flexion group than those in the extension group (p < 0.05). After 6 weeks and 6 months of rehabilitation, patients gained a similar ROM in the affected knee in both groups (p > 0.05). The length of hospital stay and medical expenses were similar in both groups. Incidence of wound infection and other complications was also similar in both groups (p > 0.05). Elevation of the hip by knee flexion of 30 degrees is an effective and simple method to reduce blood loss after TKA, and contributes to reduction of the dosage of analgesic drugs in the early postoperative period. The routine application of the present protocol also did not increase medical costs and length of hospital stay after TKA.

Abstract Background: The effectiveness of total knee arthroplasty for recovering ambulation and balance function has not been investigated in detail. The present study aimed to measure functional changes in the lower limb before and after TKA by measuring ambulation function with the 3 meters Timed Up and Go test and balance function using one-leg standing time.Methods: The study included 137 patients (116 women and 21 men) with osteoarthritis of the knee who underwent primary total knee arthroplasty. The mean age of the patients was 74.4 years. The mean postoperative hospital stay for rehabilitation was 23.9 days. The Timed Up and Go test and standing time were performed preoperatively, 2 weeks postoperatively, at discharge, and 3, 6, and 12 months postoperatively. These results from these 6 measurements were also compared using one-way analysis of variance. We also separated the patients into 3 groups by the length of hospital stay: 3 weeks or less (early discharge group), 3 to 4 weeks (standard discharge group), and over 4 weeks (late discharge group). The Timed Up and Go test and standing time among the 3 groups were evaluated at 6 measurement points.Results: Ambulation and balance function were significantly improved at 3 months after surgery. However, ambulation and balance function did not improve further from 3 months to 6 months postoperatively or from 6 months to 1 year postoperatively. Ambulation function in the early and standard discharge group were significantly lower than those in the late discharge group at all measurement points. Balance function in the early and standard discharge groups were significantly longer than those in the late discharge group preoperatively.Conclusions: Total knee arthroplasty is useful for restoring lower limb function, as both ambulation and balance function were significantly improved 3 months after surgery. Although a longer hospital stay with rehabilitation not always affected ambulation and balance function, preoperative ambulation and balance function may predict the length of hospital stay after surgery. No further improvement in ambulation or balance was recognized beyond 3 months, suggesting that further rehabilitation after hospital discharge is needed.

Background. The aim of this study was to compare outcomes in patients who received intravenous tranexamic acid just before and after total knee arthroplasty with or without drains and to analyze whether there is any difference in terms of blood loss. Material and methods. This is a retrospective analysis of prospectively collected data of patients undergoing unilateral total knee arthroplasty. Between March 2017 and March 2019, 97 knees of 94 consecutive patients with osteoarthritis were divided into two groups (Group 1, with drain; and 2, without drain). Drainage group (53 knees; average age, 66,1±7,0 years; male, 10; female, 43) and a drainless group (44 knees; average age, 63,7± 7,5 years; male, 4; female, 40). All patients received systemic tranexamic acid (in 100 mL saline infusion iv in 30 minutes prior to the tourniquet inflation and 3 hours after the operation). Blood loss, allogeneic blood transfusion rates, complications such as swelling of the cruris, infection (deep or superficial), thromboembolic incidents (Deep venous thrombosis or pulmoner thromboembolism) and length of hospital stay were assessed postoperatively. Results. There was no difference in demographic parameters, body mass index, side ofsurgery, ASA score and anesthesia type between 2 groups. The preoperative Hb levels were comparable but on the postoperative day one, Hb level was lower in the drain group (p=0,017). Total blood loss (TBL) and allogeneic transfusion rates were lower in the drainless group, although did not differ significantly between the two groups [TBL: 1360,9±502,5 / 646,1-2641,6 (1251,6) mL in the Group 1, 1205,6±505,0 / 396,6-2521,0 (1157,5) mL in Group 2 (p=0,134); Transfusion rates: 11 out of 53 cases (%20,8) in group 1 and 5 out of 44 cases (%11,4) in group 2]. The infection rate and length of hospital stay were lower in the drainless group. But there were no statistical difference was found in terms of complications and length of hospital stay between 2 groups. Conclusions. 1. Performing Total Knee Arthroplasty with preoperative and postoperative ivtranexamic acid and without drain decreased postoperative reduction in Hb level on the day after surgery in the current study. 2. But blood loss and blood transfusion rates when compared to patients with drain, no significant difference was found. 3. Drain use in knee replacements does not offer an advantage over drainless TKAs regarding the findings of our study. 4. Future studies with longer follow-up are needed in our opinion.

AbstractHyponatremia is a risk factor for adverse surgical outcomes, but limited information is available on the prognosis of hyponatremic patients who undergo total knee arthroplasty (TKA). The purpose of this investigation was to compare the incidence of major morbidity (MM), 30-day readmission, 30-day reoperation, and length of hospital stay (LOS) between normonatremic and hypontremic TKA patients.The American College of Surgeons National Surgical Quality Improvement Program database was used to identify all primary TKA procedures. Hyponatremia was defined as <135 mEq/L and normonatremia as 135 to 145 mEq/L; hypernatremic patients (>145 mEq/L) were excluded. Multivariable logistic regression was used to determine the association between hyponatremia and outcomes after adjusting for demographics and comorbidities. An α level of 0.002 was used and calculated using the Bonferroni correction. Our final analysis included 88,103 patients of which 3,763 were hyponatremic and 84,340 were normonatremic preoperatively. In our multivariable models, hyponatremic patients did not have significantly higher odds of experiencing an MM (odds ratio [OR]: 1.05; 99% confidence interval [CI] 0.93–1.19) or readmission (OR: 1.12; 99% CI: 1–1.24). However, patients with hyponatremia did experience significantly greater odds for reoperation (OR: 1.24; 99% CI: 1.05–1.46) and longer hospital stay (OR: 1.15; 99% CI: 1.09–1.21). We found that hyponatremic patients undergoing TKA had increased odds of reoperation and prolonged hospital stay. Preoperative hyponatremia may be a modifiable risk factor for adverse outcomes in patients undergoing TKA, and additional prospective studies are warranted to determine whether preoperative correction of hyponatremia can prevent complications.

Purpose: There is no consensus on the optimum timing of administration of tranexamic acid (TA) in bilateral total knee arthroplasty (TKA). We aimed to determine whether the timing of administration of single-dose intravenous TA (either given preoperatively or intraoperatively) has a significant effect on blood loss reduction. Methods: We compared two cohorts of patients with end-stage arthritis of knees who underwent bilateral TKA and were given single-dose intravenous TA (1 g or 15 mg/kg) at different times during surgery. The retrospective cohort group consisting of 40 patients (preoperative (PO) group) received TA before the skin incision. The prospective cohort consisting of 40 patients (intraoperative (IO) group) received TA 10 min before deflating the tourniquet on the first knee. Primary outcome measures were mean hemoglobin difference, A (between PO and day 1 postoperative hemoglobin), mean hemoglobin difference, B (between PO and lowest postoperative hemoglobin), and rate of allogeneic blood transfusion. Secondary measure was drain blood loss. Results: Both cohorts were well matched with respect to age, gender, duration of surgery, and length of hospital stay. The hemoglobin drop in the IO group was significantly lesser than the PO group on the first postoperative day (2 vs. 2.9 g/dL, p < 0.001). Although statistically insignificant, the patients in the IO group received less allogenic transfusion of packed cell units than in the PO group (11/40, 27.5% vs. 14/40, 35% ). Mean hemoglobin difference, B, and secondary drain loss were comparable in both groups. Conclusion: Single-dose intravenous TA given before the start of surgery is as effective as a dose given during arthroplasty of the first knee in reducing blood loss in bilateral TKA.
