Abstract
Background Previous studies have demonstrated the efficacy of bone wax in reducing blood loss in various orthopedic surgeries. However, the effect of bone wax on total hip arthroplasty (THA) remains unclear. The objective of this study was to assess the efficacy of bone wax in THA. Methods We enrolled 104 patients in this randomized controlled trial. These patients were randomized (1:1) to either the bone wax or control group. The primary outcome was total blood loss after THA. The secondary outcomes included serum hemoglobin (Hb) level, change in Hb level, lower limb diameters on the first and third postoperative day (POD), range of motion at discharge, length of postoperative hospital stay, and adverse events. Results Patients in the bone wax group had significantly lower total blood loss on PODs 1 and 3 (p < 0.05). Moreover, patients in the bone wax group performed better in terms of postoperative serum Hb level, change in Hb level on PODs 1 and 3, and length of postoperative hospital stay (all p < 0.05). Patients in the bone wax group did not experience any bone wax-related adverse events. Conclusion Bone wax administration in THA significantly reduced perioperative blood loss. Therefore, bone wax is promising for optimizing blood-conserving management protocols in THA. Clinical trial registration [https://clinicaltrials.gov/], identifier [ChiCTR2100043868].

Effect of an intensive functional rehabilitation program on the recovery of activities of daily living after total knee arthroplasty: A multicenter, randomized, controlled trial. J Orthop Sci 2020; 25:285-290. [PMID: 31182258 DOI: 10.1016/j.jos.2019.04.009] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/26/2018] [Revised: 03/27/2019] [Accepted: 04/24/2019] [Indexed: 10/26/2022]
Abstract
BACKGROUND Postoperative exercise is effective for improving activities of daily living (ADL) in patients undergoing total knee arthroplasty (TKA), and exercise has been included in standard care after surgery provided in Japan. However, it is unknown whether standard care has room to develop for improving ADL. The goal of this study was to investigate the effect of an intensive functional rehabilitation (IFR) program in addition to standard care on the recovery of ADL following surgery. METHODS A total of 104 inpatients with knee osteoarthritis undergoing TKA were randomly assigned to either the experimental or the control group. The experimental group (n = 57) were given standard care and participated in the IFR program immediately after surgery (e.g., stand up and sit down, strengthen the knee extensor muscle, climbing onto a platform, and walking laterally). The control group (n = 47) were given standard care only. Primary outcomes were the score of Functional Independence Measure (FIM) and the Barthel Index (BI) at 2 weeks postoperatively. Matching using the propensity score was performed to control the influence of the patient characteristic on the outcome. RESULTS As a result of matching, 42 patients were extracted. The averages (standard deviation) of the FIM motor score were 79.0 (10.8) for the experimental group and 80.5 (9.4) for the control group. The BI scores were 88.1 (13.3) for the experimental group and 91.0 (10.1) for the control group. The experimental and control groups did not show significant intergroup differences in either score. CONCLUSIONS Our study shows that as compared to standard care, IFR program for 2 weeks in addition to standard care after surgery did not significantly improve ADL in patients undergoing TKA.

Thromb Res 2020; 188:39-43. [PMID: 32045773 DOI: 10.1016/j.thromres.2020.02.001] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/22/2019] [Revised: 12/02/2019] [Accepted: 02/03/2020] [Indexed: 02/02/2023]
Abstract
BACKGROUND Total knee arthroplasty (TKA) has been considered as an effective choice for end-stage osteoarthritis or rheumatic arthritis. Tranexamic acid (TXA) has been widely used to prevent excessive blood loss perioperatively. Similarly, hemocoagulase atrox can significantly diminish blood loss and transfusion requirements in surgeries, however, it was rarely used in TKA. The purpose of this study is to identify whether hemocoagulase atrox is equal to TXA in reducing blood loss and transfusion rates following TKA, and compare clinical outcomes and complications between the two groups. METHODS 74 patients were randomized to receive TXA (1.5 g intra-articular combined with 1.5 g intravenous), or hemocoagulase atrox (1 U intra-articular combined with 1 U intravenous). The primary outcome was total blood loss. The secondary outcomes included reduction of hemoglobin concentration, clinical outcomes, blood coagulation values, thromboembolic complications, and transfusion rates. RESULTS The mean total blood loss was 431.7 mL in the TXA group compared with 644.6 mL in the hemocoagulase atrox group, with statistical significance (P < 0.05). There were significant differences in reduction of hemoglobin level (P < 0.05). The rate of deep vein thrombosis (DVT) in patients given TXA was higher than those given hemocoagulase atrox, however, there were no significant differences. No transfusions were required in either group, and no significant differences were found in the length of hospital stay and clinical outcomes. CONCLUSIONS Although the blood loss was significantly greater in the hemocoagulase atrox group, no transfusions were required and no significant differences were observed for any other outcomes measured. Meanwhile, the rate of DVT in the hemocoagulase atrox group tends to be lower than those in TXA group. We concluded that hemocoagulase atrox was not superior to TXA in reducing perioperative blood loss. Further studies are warranted to evaluate if hemocoagulase atrox use could improve perioperative blood loss in patients with high thrombotic risk undergoing TKA.

Abstract
Background The accelerometer-based navigation (ABN) system is an emerging navigation system for total knee arthroplasty (TKA). This study aimed to determine whether the ABN system could improve the accuracy of mechanical alignment, component positioning, and short-term clinical outcomes for TKA when compared to conventional instruments (CON). Methods A total of 204 patients were selected and divided into two groups (CON: 135, ABN: 69) after applying the inclusion and exclusion criteria. Then, 1:1 propensity score matching was performed for age, gender, body mass index, hip-knee-ankle angle (HKA), Knee Society Score (KSS), Western Ontario and McMaster Universities (WOMAC) score, and follow-up times. A total of 82 consecutive patients (82 knees) underwent total knee arthroplasty using ABN (n = 41) or CON (n = 41) were enrolled in this study. The postoperative HKA, frontal femoral component (FFC) angle, frontal tibial component (FTC) angle, lateral femoral flexion (LFF) angle, and lateral tibial component (LTC) angle were compared between the two groups to evaluate mechanical alignment and component positioning. Additional clinical parameters, including haemoglobin reduction, the KSS, and the WOMAC score, were assessed at the final follow-up (the mean follow-up period was 20.9 months in the CON group and 21.2 months in the ABN group). Results The ABN group had a significantly improved mean absolute deviation of HKA (P = 0.033), FFC (P = 0.004), FTC (P = 0.017), LFF (P = 0.023), and LTC (P = 0.031) compared to those of the CON group. The numbers of FFCs and LTCs within 3° were significantly different (P = 0.021, P = 0.023, respectively) between the two groups. However, no differences in the numbers of FTCs within 3° (P = 0.166) and LFF within 3° (P = 0.556) were found. The ABN group had a significantly higher KS function score (P = 0.032), and the pain and stiffness scores were significantly different (P = 0.034, P = 0.020, respectively) between the two groups. Moreover, the ABN system could reduce hidden blood loss postoperatively. However, no difference was found in the KS knee score and the total WOMAC score between the two groups. Conclusion This study demonstrates that ABN system improved TKA mechanical alignment and component positioning and decreased the hidden blood loss postoperatively compared to conventional instruments. However, no significant differences were found in short-term clinical outcomes between ABN and conventional instruments at the final follow-up. However, whether this system contributes to revision rates and long-term clinical outcomes requires further study.

Abstract
BACKGROUND The use of tranexamic acid (TXA) has been proved to be effective in reducing blood loss and transfusion requirements after primary total knee arthroplasty (TKA). However, the evidence for its use in revision surgery is scant. We assessed the safety and efficacy of topical TXA in revision TKA. METHODS We retrospectively compared 76 revision TKA patients who received topical TXA (3 g before tourniquet deflation) "study group" with a historic control group of 205 revision TKA patients in which TXA was not used. Each group was further stratified into subgroups according to the type of revision. All patients were followed for a minimum of 6 weeks. Blood loss, transfusion requirements, changes in hemoglobin-hematocrit levels, Knee Society Score, and complications were recorded. RESULTS The mean estimated blood loss, hemoglobin drop, and transfusion rate were significantly lower in the study group than in the control group (P = .008, P < .001, P < .001, respectively). Hidden blood loss was similar between the 2 groups (P = .12). Six weeks postoperatively, the improvement in the knee-specific Knee Society Score was significantly higher in the study group than in the control group (P < .001). No significant differences were found in thromboembolic complications between the 2 groups (P = .92). In the subgroup analysis, when both components (femur and tibia) were revised, the relative risk of transfusion was significantly lower with the use of TXA (relative risk 0.227, confidence interval 0.0593-0.860, P = .004). CONCLUSION Topical TXA in revision TKA is safe and effective in reducing blood loss and transfusions. This effect is enhanced when both components are revised. Additionally, the use of TXA may improve early outcomes.

Abstract
Objective The aim of this study was to assess the effect of topical tranexamic acid on blood loss and transfusion rates in acetabular fracture surgery. Methods The medical records of 61 patients who underwent open reduction and internal fixation for acetabular fracture between 2012 and 2015 were retrospectively reviewed. The patients were divided into two groups: Group I consisted of 31 patients (19 men and 12 women, mean age: 52 ± 19 years) who received intraoperatively a topical tranexamic acid solution of 3 g and Group 2 consisted of 30 control patients (17 men and 13 women, mean age: 48 ± 24 years) who received only 0.9% saline solution. The groups were compared based on their intraoperative blood loss, Postoperative drain output at 24 and 48 h, and postoperative hemoglobin levels, and transfusion rates. Results The mean intraoperative blood loss was 410 ± 100 ml in Group 1, compared to 570 ml ± 160 ml of the control group (p < 0.05). The postoperative drain output after 24 h was 210 ± 70 ml in Group 1 compared to 330 ± 90 ml of the control group (p < 0.05). The drain output at 48 h was (50 ± 20 ml) in group 1 compared to 90 ± 40 ml of the control group (p < 0.05). The transfusion rate was significantly low group 1 (42%) than the control group (97%). Hemoglobin drop was again significantly less in tranexamic acid group (2.1 ± 1.1) than the control group (3.2 ± 1.3). The nadir postoperative hemoglobin was higher in the Group 1 (10.4 ± 1.5) than the control group (9.2 ± 1.3). Conclusion Topical administration of tranexamic acid reduces intraoperative and postoperative blood loss in acetabular fracture surgery, decreasing transfusion rates.

Abstract
BACKGROUND Previous studies have confirmed that, compared with intravenous and intra-articular formulations, oral tranexamic acid (TXA) provides equivalent reduction in blood loss, at a substantially reduced cost and greater ease of administration. However, the optimal oral dosage regimen to achieve maximum blood-loss reduction remains unclear. The aim of this study was to assess the efficacy of a regimen of multiple doses of oral TXA on blood loss in primary total hip arthroplasty. METHODS In this randomized controlled trial, 200 patients were randomized to 1 of 4 interventions. Group A received a single dose of 2.0 g of TXA orally at 2 hours preoperatively. In addition to this same preoperative dose, Group B received 1.0 g of TXA orally at 3 hours postoperatively, Group C received 1.0 g of TXA orally at 3 and 9 hours postoperatively, and Group D received 1.0 g of TXA orally at 3, 9, and 15 hours postoperatively. All patients received a 1.0-g topical dose of TXA. The primary outcome was total blood loss. Secondary outcomes included hemoglobin reduction, transfusion rate, thromboembolic complications, and adverse events. RESULTS The mean total blood loss (and standard deviation) was significantly less in Groups B, C, and D (792.2 ± 293.0, 630.8 ± 229.9, and 553.0 ± 186.1 mL, respectively) than in Group A (983.6 ± 286.7 mL) (p < 0.001). Moreover, Groups C and D had a lower mean reduction in hemoglobin than did Groups A and B. However, no differences were identified between Groups C and D for blood loss and hemoglobin reduction. Additionally, no differences were observed among the groups regarding thromboembolic complications and transfusions. CONCLUSIONS The multiple postoperative doses of oral TXA further reduced blood loss compared with a single preoperative bolus. The regimen of a preoperative dose and 3 postoperative doses of oral TXA produced maximum effective reduction of blood loss in total hip arthroplasty. LEVEL OF EVIDENCE Therapeutic Level I.

Abstract
BACKGROUND Total knee arthroplasty (TKA) is associated with blood loss and an increased risk of transfusion. Guidelines for antifibrinolytic drug tranexamic acid (TXA) treatment in TKA patients are available. We evaluated the effects of anticoagulant pharmacist intervention on perioperative blood conservation treatment in TKA patients. METHODS In a retrospective, observational experimental study, patients admitted for TKA were allocated into the control or pharmacist intervention group. In the intervention phase, multiple interventions of TXA treatment based on guidelines were implemented. The primary endpoint was blood loss. Other outcome included postoperative haemoglobin and haematocrit levels, allogeneic blood transfusion, cost savings and safety. RESULTS A total of 177 patients were included (88 and 89 in the control and intervention group, respectively). In the intervention group, 24.72% orders of TXA dosage, 20.22% orders of drug choice, 26.97% orders of TXA timing and 30.34% orders of TXA administration manner were adjusted. Eighty-nine (100%) patients received blood conservation therapy compared with 21 (23.86%) patients in the control group (P < 0.001). Total blood loss was 1133.31 ± 627.08 mL in the control group compared with 604.34 ± 459.09 mL in the intervention group (P < 0.001). Postoperative drops in haemoglobin and haematocrit in the control group were greater than in the intervention group (P < 0.001). The rate of allogeneic blood transfusion was 40.91% in the control group compared with 21.35% in the intervention group (P = 0.01). Pharmacist intervention was conducted to cost savings resulting from reduced transfusion, but with comparable safety profile. CONCLUSIONS Anticoagulant pharmacist intervention on blood conservation treatment of TKA patients leads to favourable clinical and economic outcome.

Abstract
BACKGROUND To investigate the clinical effectiveness of intravenous (IV) and topical tranexamic acid (TXA) in patients undergoing total knee arthroplasty (TKA) by comparing safety, efficacy and patient-reported outcomes. METHODS In this prospective single-blind clinical trial, 64 patients were randomized into two groups (n = 32 each). The Intravenous Group was administered TXA 10 mg/kg IV (Reyong, Shandong, China) 10 min prior to tourniquet deflation. In the Topical Group, 1.0 g TXA diluted in 50 ml of normal saline was injected into the surgical site, which was bathed in the solution for at least 5 min prior to tourniquet deflation. Outcomes included changes in hemoglobin levels, intra-operative, post-operative, and total blood loss, number of transfusions and number of transfused units, patient-reported postoperative Visual Analog Scale (VAS) score for knee pain, and complications. RESULTS There were no significant differences in intra-operative blood loss, post-operative blood loss, total blood loss, or post-operative decrease in hemoglobin in the Intravenous Group versus the Topical Group. The number of transfused red blood cell units was significantly greater and-post-operative VAS score was significantly lower in the Intravenous Group. There were no differences in post-operative thromboembolic complications between groups. CONCLUSIONS Topical TXA is not inferior to IV administration in reducing perioperative blood loss in primary TKA. However, the influence of injection volume of locally applied TXA on post-operative knee pain warrants further investigation.

Abstract
BACKGROUND Primary total hip arthroplasty (THA) and conversion THA may result in substantial blood loss, sometimes necessitating transfusion. Despite the complexities of the latter, both are grouped in the same category for quality assessment and reimbursement. This study's purpose was to compare both blood loss and transfusion risk in primary and conversion THA and identify their associated predictors. METHODS A total of 1616 patients who underwent primary and conversion THA at a single hospital from 2009-2013 were reviewed (primary THA = 1575; conversion THA = 41). Demographics, comorbidities, and perioperative data were collected from electronic records. Blood loss was calculated using a validated method. Transfusion triggers were based on standardized criteria. Separate multivariable regression models for blood loss and transfusion were performed. RESULTS Conversion THA patients were younger (P = .002), had lower age-adjusted Charlson scores (P = .006), longer surgeries (P < .001), higher blood loss (P < .001), and more transfusions (P < .001). Primary and conversion THA groups were different in terms of surgical approach (P < .001), anesthesia type (P = .002), and venous thromboembolism prophylaxis (P = .01). Compared to primary THA, conversion THA had an average 478.9 mL higher blood loss (P = .003) and increased adjusted odds ratio of 3.2 (P = .019) for transfusion. CONCLUSION Conversion THA leads to higher blood loss and transfusion compared with primary THA. These differences were quantified in the present study and showed consistent results between the 2 metrics. The differences between these procedures should be addressed during quality assurance because conversion THA is associated with higher resource utilization, which is important in the allocation of resources and tiered reimbursement strategies.

Abstract
Background: A combined intravenous and intra-articular regimen is one of the most effective administration routes of tranexamic acid (TXA) to reduce perioperative blood loss in unilateral total knee arthroplasty. However, there have been few reports regarding use of the combined regimen for patients undergoing simultaneous bilateral total knee arthroplasty, in which blood-management strategy is more challenging. Methods: We compared perioperative blood loss in 30 consecutive patients undergoing simultaneous bilateral total knee arthroplasty who received both 1,000 mg of TXA intravenously and 1,000 mg of intra-articular TXA in each knee (combined TXA group) with that in a consecutive series of 51 patients who only received 1,000 mg of TXA intravenously (intravenous TXA group). Additional intravenous TXA was administered 6 hours after the initial administration in both groups. Except for the intraoperative TXA administration regimen, an identical perioperative blood-management strategy was applied to both groups; this consisted of transfusion of 800 or 400 mL of predeposited autologous blood except for patients with a preoperative hemoglobin level of <11.0 g/dL, who received 4 units of allogenic blood. All surgical procedures were performed with spinal anesthesia and without use of a pneumatic tourniquet. Perioperative blood loss was calculated using the blood volume and change in hemoglobin level from the preoperative measurement to postoperative day 3. Results: There was significantly less perioperative blood loss in the combined TXA group compared with the intravenous TXA group (mean and standard deviation, 1,201 ± 347 versus 1,638 ± 400 mL, respectively; mean difference, 437 mL; 95% confidence interval, 263 to 613 mL; p < 0.0001). No patient in the combined TXA group and 1 patient (2%) in the intravenous TXA group required additional allogenic blood transfusion. No thrombotic events occurred in either group. Conclusions: In a nonrandomized comparison, combined intra-articular and intravenous TXA significantly reduced the calculated perioperative blood loss in simultaneous bilateral total knee arthroplasty compared with that found in patients treated only with intravenous TXA. Level of Evidence: Therapeutic Level III. See Instructions for Authors for a complete description of levels of evidence.

Abstract
Purpose Postoperative hemoglobin (Hb) determination remains an essential parameter for quantifying blood loss following total knee replacement (TKR) surgery and guiding transfusion practice. In this study we aimed to ascertain the optimal timing for Hb determination postoperatively and assess its relationship to serum hematocrit (Hct). Materials and Methods This was a retrospective cohort analysis of 61 consecutive patients undergoing preoperative, day 1 and day 2 Hb and Hct concentration determination following TKR surgery. This was a single centre study in the United Kingdom. Results The mean fall in Hb concentration at day 1 was 2.9 g/dL in comparison to 3.3 g/dL at day 2. This indicated a significant difference of 0.39 g/dL (p=0.023). A total of 5 patients required blood transfusions following day 2 Hb determination. Postoperative Hct values varied in close relation with the Hb concentration with no significant differences demonstrated. Our study reveals a significant change between day 1 and day 2 Hb concentrations following TKR surgery, with no significant differing information provided through Hct determination. Conclusions Our results support the use of delayed routine testing at day 2 following surgery as it is likely to more accurately reflect ongoing hidden blood loss into the joint cavity and within soft tissue planes.

Abstract
Background Autologous blood transfusion drainage (ABTD) has been used for many years to reduce blood loss in total knee arthroplasty (TKA). We evaluate the current evidence concerning the efficiency and safety of ABTD used in TKA compared with conventional suction drainage (CSD). Methods We performed a systematic literature search of the PubMed, Embase, Cochrane Library and four Chinese databases. All randomized controlled trials (RCTs) that compared the effects of ABTD versus CSD in TKA were included in the meta-analysis. Results Sixteen RCTs involving 1534 patients who compared the effects of ABTD versus CSD were included. Five of the RCTs were performed in Asia, ten in Europe, and one in North America. Patients in the ABTD group had a lower blood transfusion rate (OR: 0.25 [0.13, 0.47]; Z = 4.27, P < 0.0001) and fewer units transfused per patient (WMD: −0.68 [−0.98, −0.39]; Z = 4. 52, P < 0.00001) than did patients in the CSD group. Wound complications, deep vein thrombosis, febrile complications, post-operative hemoglobin days 5–8, drainage volume, and length of hospital stay did not differ significantly between the two types of drainage systems. Conclusion This meta-analysis suggests that ABTD is a safe and effective method that yields a lower blood transfusion rate and fewer units transfused per patient in TKA compared with CSD.

Abstract
Background The purpose of this study was to compare 2 blood management interventions, tranexamic acid (TXA) and bipolar sealer system (BSS) used independently or in combination with a control group during primary total knee arthroplasty (TKA). Methods A total of 127 TKA patients were enrolled and randomized into 4 groups: Intravenous TXA plus the BSS (N = 29, group 1); TXA only (N = 29, group 2); BSS only (N = 31, group 3); and intravenous normal saline as a control group (N = 32, group 4). Results Changes in hemoglobin from baseline to postoperative follow-up were significantly lower among patients who received TXA plus BSS and those receiving TXA only when compared with the control. BSS only did not differ significantly when compared to the control group. In addition, TXA plus BSS was as efficacious as TXA only in preserving postoperative hemoglobin. Conclusions In other terms, using bipolar sealer did not add to the effect of TXA in reducing the postoperative hemoglobin drop in primary TKA.

Abstract
Background and Objectives. The null hypothesis of this study was that TA has no effect on postsurgical bleeding in patients undergoing TKA. Methods. This study was a double-blind randomized trial. In the first group (T) patients received 500 mg of intravenous Tranexamic acid (TA) twice (once preoperatively and once 3 hours postoperatively) and in the second group (P) they received slow infusion of normal saline as placebo. The primary outcome of the study was the level of Hb 48 hours after surgery. Results. Hb levels 48 hours after surgery as the primary outcome were 10.92 ± 0.97 and 10.23 ± 0.98 (g/dL) in groups T and P, respectively, and the difference was statistically significant (P = 0.001). Statistically significant differences were also observed in Hb levels 6 and 24 hours after surgery, the drain output 48 hours after surgery, and the number of units of packed cells transfused between study groups (P < 0.05). There was no significant difference in duration of hospitalization between the study groups (P = n.s.). Conclusions. The low dose perioperative intravenous TA significantly reduces blood loss, requirement for blood transfusion, and drain output in patients undergoing TKA. However, duration of hospitalization did not change significantly.

Abstract
The goal of the clinical use of a bipolar blood-sealing system is to reduce perioperative blood loss in total joint arthroplasty (TJA). This study was performed to determine whether a bipolar sealer is safe and effective in TJA and whether there are any advantages over monopolar sealers. The authors searched electronic databases and reference lists of relevant articles; retrieved all published randomized, controlled trials concerning the subject; and then performed a meta-analysis. Nine clinical trials involving 871 patients were included. The results of the meta-analysis indicate that using a bipolar sealer in TJA could reduce total measured blood loss, intraoperative blood loss, and operative time, which was especially observed in revision TJA for infection and primary total knee arthroplasty without tourniquet use. However, there was no significant difference between the 2 groups in terms of calculated blood loss, hemoglobin decrease, transfusion requirements, length of stay, and complications. The results of the comparison between bipolar and monopolar sealers used in TJA indicate that the routine use of a bipolar sealer for TJA may be of limited benefit except in revision TJA and primary total knee arthroplasty without tourniquet use. In the future, more high-quality randomized, controlled trials are needed to provide robust evidence and confirm the best option.

Abstract
PURPOSE Blood loss can be substantial and will influence morbidity and mortality after total knee arthroplasty. This study evaluated whether patient-specific instruments (PSI) can reduce blood loss because the intramedullary canal is not opened during the procedure and whether hidden blood loss can be reduced by its use. METHODS Seventy-five patients operated with the Signature PSI technique were compared with a matched group operated with conventional instruments. Maximal drop in haemoglobin (Hb) and hematocrit (HTC) level were compared at day 2 and day 4. Transfusions were noted. Clinical outcomes like range of motion and knee society scores were studied as secondary outcomes. RESULTS No statistically significant difference for calculated blood loss, maximal drop in Hb or HTC and transfusions were found. No clinical differences in range of motion or knee society scores were observed. CONCLUSIONS The use of PSI-assisted total knee arthroplasty (TKA) did not result in less blood loss compared with conventional minimally invasive TKA with tourniquet. No reduction in hidden blood loss was observed either. According to this study, the argument of reduced transfusion cost should not be used in cost-effectiveness calculations of PSI-assisted TKA.

Abstract
INTRODUCTION Tranexamic acid (TXA) is becoming widely used in orthopedic surgery to reduce blood loss and transfusion requirements, but consensus is lacking regarding the optimal route and dose of administration. The aim of this study was to compare the efficacy and safety of topical and intravenous routes of TXA with routine hemostasis in patients undergoing primary total knee arthroplasty (TKA). MATERIALS AND METHODS We performed a randomized, multicenter, parallel, open-label clinical trial in adult patients undergoing primary TKA. Patients were divided into three groups of 50 patients each: Group 1 received 1 g topical TXA, Group 2 received 2 g intravenous TXA, and Group 3 (control group) had routine hemostasis. The primary outcome was total blood loss. Secondary outcomes were hidden blood loss, blood collected in drains, transfusion rate, number of blood units transfused, adverse events, and mortality. RESULTS One hundred and fifty patients were included. Total blood loss was 1021.57 (481.09) mL in Group 1, 817.54 (324.82) mL in Group 2 and 1415.72 (595.11) mL in Group 3 (control group). Differences in total blood loss between the TXA groups and the control group were clinically and statistically significant (p < 0.001). In an exploratory analysis differences between the two TXA groups were not statistically significant (p = 0.073) Seventeen patients were transfused. Transfusion requirements were significantly higher in Group 3 (p = 0.005). No significant differences were found between groups regarding adverse events. CONCLUSION We found that 1 g of topical TXA and 2 g of intravenous TXA were both safe strategies and more effective than routine hemostasis to reduce blood loss and transfusion requirements after primary TKA.

Abstract
BACKGROUND CONTEXT Length-of-hospital stay (LOS) after lumbar spine surgery (LSS) can be affected by many factors. However, few studies have evaluated predictors of LOS, and all have used limited number of variables as predictors. PURPOSE The purpose of the study was to identify presurgical, surgical, and postsurgical predictors of LOS after LSS. STUDY DESIGN/SETTING Retrospective review of consecutive patients who had LSS at the University of Kansas Hospital from October 2008 to April, 2012. PATIENT SAMPLE Five hundred ninety-three patients underwent LSS consisting of laminotomy, laminectomy, or arthrodesis. DEPENDENT VARIABLE LOS. Multiple presurgical, surgical, and postsurgical variables were extracted from the patients' medical records and considered as possible predictors (independent variables) of LOS. METHODS Potential predictors that were significantly correlated with LOS were used as indicators to construct three latent factors presurgical, surgical, and postsurgical, which were in turn used to predict LOS in a structural equation model. RESULTS The average LOS was 4.01±2.73 days. The presurgical factor was indicated by age (61.97±14.49 years), previous level of function (60.5% were totally independent), previous hemoglobin level (13.70±1.36 mg/dL), and use of assistive devices (60% were assistive device users). The surgical factor was indicated by severity of illness (50.2% had minor disease severity), presence of complications (1.9%), and stay in an intensive care unit (4.0%). The postsurgical factor was indicated by postsurgical walking distance (166.43±175.75 ft), level of assistance during walking (5.18±0.81 out of 7 points), balance scores (6.18±1.82 out of 10 points), and bed mobility and transfer dependency scores (9.81±1.99 out of 14 points). These three latent factors explained 47% of variation in LOS. CONCLUSIONS Postsurgical factors predicted the highest variation in LOS in comparison with presurgical and surgical factors and should be taken into consideration for discharge planning. Postsurgical factors are related to the patient's function, modifiable with rehabilitation, and can be improved to shorten LOS. Inclusion of more reliable and standardized presurgical variables could improve the predictability of the model.

Abstract
The purpose of this study was to compare the efficacy of topical Tranexamic Acid (TXA) versus Intravenous (IV) Tranexamic Acid for reduction of blood loss following primary total knee arthroplasty (TKA). This prospective randomized study involved 89 patients comparing topical administration of 2.0g TXA, versus IV administration of 10mg/kg. There were no differences between the two groups with regard to patient demographics or perioperative function. The primary outcome measure, perioperative change in hemoglobin level, showed a decrease of 3.06 ± 1.02 in the IV group and 3.42 ± 1.07 in the topical group (P = 0.108). There were no statistical differences between the groups in preoperative hemoglobin level, lowest postoperative hemoglobin level, or total drain output. One patient in the topical group required blood transfusion (P = 0.342). Based on our study, topical Tranexamic Acid has similar efficacy to IV Tranexamic Acid for TKA patients.

Abstract
BACKGROUND Systemic tranexamic acid can decrease blood loss and rates of transfusion in patients undergoing total hip arthroplasty (THA). However, the efficacy of topical tranexamic acid in THA has only recently been characterized in a small number of studies. QUESTIONS/PURPOSES The purpose of this study was to compare (1) the greatest hemoglobin decrease after surgery; (2) transfusion rates; and (3) symptomatic thromboembolic events among patients undergoing THA who did and did not receive topical tranexamic acid. METHODS We retrospectively compared 135 patients (154 THAs) who received 10 mL 5% tranexamic acid added in a topical cocktail solution during surgery between January 2009 and July 2011 with 211 patients (234 THAs) who received only the topical cocktail solution (analgesic and antibiotic agent) between January 2005 and December 2008. Contraindications for the use of tranexamic acid included a documented history of a venous thromboembolic event, an allergy to tranexamic acid, thrombophilia, or a high risk of venous thromboembolism based on the guidelines of the American Academy of Orthopaedic Surgeons; the 135 patients who received it during that period represented 99.4% of the patients undergoing THA during that time. We compared changes in Hb, transfusion rates, estimated blood loss, surgical results, and complications between the groups. The transfusion threshold was the same, when the Hb values were < 10 g/dL. Patients were screened for thromboembolic disease if symptoms or signs appeared. RESULTS Hb decreased less in the tranexamic acid group (1.87 ± 1.10 g/dL) than in the control group (2.2 ± 1.36 g/dL; p = 0.01) on the first postoperative day. The frequency of transfusion was lower in patients receiving tranexamic acid (17% as compared with 35% in the control group; p < 0.001). There was only one nonfatal pulmonary embolism in the control group during the study period. CONCLUSIONS Use of topical tranexamic acid in patients undergoing THA reduces postoperative bleeding and decreases blood transfusion rates. No increase in major complications was identified in patients managed with topical tranexamic acid. This retrospective study confirms the results of a smaller randomized trial on the same topic by another group. LEVEL OF EVIDENCE Level III, therapeutic study.

Platelet-rich plasma prevents blood loss and pain and enhances early functional outcome after total knee arthroplasty: a prospective randomised controlled study. INTERNATIONAL ORTHOPAEDICS 2013; 38:387-95.

Abstract
PURPOSE The purpose of this study was to determine whether platelet-rich plasma (PRP) might prevent blood loss and postoperative pain and expedite wound healing following total knee arthroplasty (TKA). METHODS Forty consecutive patients with knee arthritis who were matched for age, sex and body mass index (BMI) were randomly allocated to either receive or not receive PRP application over the wound, including capsule, medial and lateral recesses, during TKA. Postoperative haemoglobin, blood loss, blood transfusion, visual analogue scale (VAS) score, wound score, Knee Society Score (KSS) and Western Ontario and McMaster Osteoarthritis Index (WOMAC) score were recorded and evaluated. RESULTS The platelet-rich plasma and control groups comprised 17 and 23 patients, respectively. The PRP group recorded significantly less reduction in haemoglobin and need for blood transfusion (p = 0.00 and p = 0.001, respectively), experienced less pain (p = 0.00) and required fewer narcotics than the control (p = 0.00). There was significant difference in range of motion (ROM) at three months (p = 0.01), no significant difference in wound scores (p = 0.311) and significant difference in KSS and WOMAC scores at 12 weeks (p = 0.00, 0.00). However no significant difference was found at six months. CONCLUSIONS PRP has significant effect in preventing blood loss, postoperative pain and need for narcotics after TKA and has a positive effect on short-term clinical outcome.

Abstract
OBJECTIVES To (1) identify all available rehabilitation impact indices (RIIs) based on their mathematical formula, (2) assess the evidence for independent predictors of each RII and (3) propose a nomenclature system to harmonise the names of RIIs. DESIGN Systematic review. DATA SOURCES PubMed and references in primary articles. STUDY SELECTION First, we identified all available RII through preliminary literature review. Then, various names of the same formula were used to identify studies, limited to articles in English and up to 31 December 2011, including case-control and cohort studies, and controlled interventional trials where RIIs were outcome variable and matching or multivariate analysis was performed. RESULTS The five RIIs identified were (1) absolute functional gain (AFG)/absolute efficacy/total gain, (2) rehabilitation effectiveness (REs)/Montebello Rehabilitation Factor Score (MRFS)/relative functional gain (RFG), (3) rehabilitation efficiency (REy)/length of stay-efficiency (LOS-EFF)/efficiency, (4) relative functional efficiency (RFE)/MRFS efficiency and (5) revised MRFS (MRFS-R). REy/LOS-EFF/efficiency had the most number of supporting studies, followed by REs and AFG. Although evidence for different predictors of RIIs varied according to the RII and study population, there is good evidence that older age, lower prerehabilitation functional status and cognitive impairment are predictive of poorer AFG, REs and REy. CONCLUSIONS 5 RIIs have been developed in the past two decades as composite rehabilitation outcome measures controlling premorbid and prerehabilitation functional status, rate of functional improvement, each with varying levels of evidence for its predictors. To address the issue of multiple names for the same RII, a new nomenclature system is proposed to harmonise the names based on common mathematical formula and a first-named basis.

Abstract
Tranexamic acid (TNA) reduces postoperative blood loss in general and obstetrical surgery but there is limited orthopaedic literature regarding its use in the topical setting. To study the effect of topical TNA after primary total knee arthroplasty (TKA), 101 patients were randomized to topical administration of 2.0g TNA in 75mL of normal saline (50 patients) or placebo (51 patients). Operative technique, drug administration, and venous thromboembolism prophylaxis were standardized. All patients underwent screening ultrasound of the operative extremity. Total blood loss was lower in the TNA group (940.2±327.1mL) than the placebo group (1293.1±532.7mL)(P<0.001), and four patients in the placebo group and none in the TNA group received postoperative transfusion (P=0.118). We recommend administration of topical TNA in primary TKA in healthy patients to decrease perioperative blood loss.

Abstract
PURPOSE Reduction in blood loss during surgery stabilizes hemodynamic status and aids in recovery after total knee arthroplasty (TKA). In this study, the authors examined whether different administration routes of tranexamic acid (TNA) might affect the amount of blood loss after TKA. METHODS A total of 150 patients were prospectively allocated to each of the three groups (intravenous, intra-articular, and placebo group) and underwent unilateral TKA. During closing the operative wound, TNA (1.5 g mixed in 100 cc of saline) was administered intravenously or intra-articularly according to the enrolled group, and an equivalent volume of normal saline was administered into the knee joint cavity and intravenously in the placebo group, respectively. The amount of blood loss and transfusion, and changes in haemoglobin levels were documented accordingly. RESULTS The mean blood loss in the intravenous, intra-articular, and placebo groups were 528 ± 227, 426 ± 197, and 833 ± 412 ml, respectively. About 66 % (intravenous), 80 % (intra-articular), and 6 % (placebo) of each group did not require transfusion for any reason, and the mean amount of transfusion was 273.6, 129.6, and 920.8 ml, respectively. Preoperative haemoglobin values decreased by 1.6 ± 0.8, 1.8 ± 0.8, and 2.0 ± 0.9 mg/dl, respectively. CONCLUSION Compared to intravenous administration, intra-articular administration of TNA seems to be more effective in terms of reducing blood loss and transfusion frequency. TNA may improve the general conditions of patients given TKA by maintaining a hemodynamically stable state, aiding in recovery, and reducing the chance of transfusion-associated side effects and complications.

Abstract
The purpose of this study was to investigate whether unipolar or bipolar hemostasis is more effective in reducing blood loss associated with primary total knee arthroplasty. We randomized 113 consecutive patients undergoing primary total knee arthroplasty into unipolar and bipolar hemostasis treatment groups. The mean postoperative drain output in the unipolar group was 776.5 mL compared with 778.7 mL and was not statistically significant (P = .97). There were no statistically significant differences in postoperative day 1 through 3 hemoglobin level (P = .2-.6) or hematocrit (P = .17-.46) values. The transfusion requirement in the unipolar group was 36% and 40% in the bipolar group (P = .67). Use of bipolar sealer compared with standard unipolar electrocauterization showed no significant difference in postoperative drain output, postoperative hemoglobin level and hematocrit values, or transfusion requirements.

Abstract
BACKGROUND Anemia is a frequent co-morbidity in the elderly patients undergoing hip or knee surgery and is often associated with poor clinical outcomes. Mild to moderate anemia is often treated with intravenous or oral iron supplementation. However, the efficacy and safety of iron supplementation in treating anemia for the elderly patients undergoing hip or knee surgery remains controversial. METHODS Only prospective, randomized studies that compared iron supplementation with no iron supplementation in the elderly patients undergoing hip or knee surgery were included. Six studies met the inclusion criteria: the target population consisted of patients undergoing hip or knee surgery treated with iron supplementation; the study was a published randomized trial. Each outcome measure tested was assessed for heterogeneity. If significant heterogeneity was present for more than 75%, data from the studies were not combined. If there was no significant heterogeneity (less than 40%), a weighted mean difference (WMD) or combined relative risk was calculated using a fixed effects model, while a random effects model was applied when heterogeneity was within 40% to 75%. RESULTS Our meta-analysis demonstrated the increase of hemoglobin level in patients undergoing hip or knee surgery with iron supplementation. However, no significant difference on the length of hospital stay, morbidity, 1-mo mortality, the infection rate, the rate and volume of allogeneic blood transfusions, and the adverse drug effects was found between the patients with iron treatment and those without. CONCLUSION Our meta-analysis suggested that iron supplementation was safe and effective in treating anemia for the elderly patients undergoing hip or knee surgery.

Abstract
BACKGROUND Topical application of tranexamic acid to bleeding wound surfaces reduces blood loss in patients undergoing some major surgeries, without systemic complications. The objective of the present trial was to assess the efficacy and safety of the topical application of tranexamic acid on postoperative blood loss in patients undergoing primary unilateral total knee arthroplasty with cement. METHODS In a prospective, double-blind, placebo-controlled trial, 124 patients were randomized to receive 1.5 or 3.0 g of tranexamic acid in 100 mL of normal saline solution or an equivalent volume of placebo (normal saline solution) applied into the joint for five minutes at the end of surgery. The primary outcome was blood loss calculated from the difference between the preoperative hemoglobin level and the corresponding lowest postoperative value or hemoglobin level prior to transfusion. The safety outcomes included Doppler ultrasound in all patients and measurement of plasma levels of tranexamic acid one hour after release of the tourniquet. RESULTS Twenty-five patients were withdrawn for various reasons; therefore, ninety-nine patients were included in the intention-to-treat analysis. The postoperative blood loss was reduced in the 1.5 and 3-g tranexamic acid groups (1295 mL [95% confidence interval, 1167 to 1422 mL] and 1208 mL [95% confidence interval, 1078 to 1339 mL], respectively) in comparison with the placebo group (1610 mL [95% confidence interval, 1480 to 1738 mL]) (p < 0.017). The postoperative hemoglobin levels were higher in the 1.5 and 3.0-g tranexamic acid groups (10.0 g/dL [95% confidence interval, 9.5 to 10.4 g/dL] and 10.1 g/dL [95% confidence interval, 9.8 to 10.5 g/dL], respectively) in comparison with the placebo group (8.6 g/dL [95% confidence interval, 8.2 to 9 g/dL]) (p < 0.017). With the numbers studied, there was no difference in the rates of deep-vein thrombosis or pulmonary embolism between the three groups. Minimal systemic absorption of tranexamic acid was observed. CONCLUSIONS At the conclusion of a total knee arthroplasty with cement, topical application of tranexamic acid directly into the surgical wound reduced postoperative bleeding by 20% to 25%, or 300 to 400 mL, resulting in 16% to 17% higher postoperative hemoglobin levels compared with placebo, with no clinically important increase in complications being identified in the treatment groups.

Abstract
PURPOSE To examine the effects of anemia on inpatient rehabilitation outcomes following unilateral and bilateral total knee arthroplasty (TKA). METHOD This was a multicenter, retrospective study from 15 inpatient rehabilitation facilities. Patients (N = 5421) with very low hematocrit (Hct <30%), low Hct (30-36% women, 30-41% men), or normal Hct (>36% women, 41% men) were included. Inpatient rehabilitation occurred following TKA. Functional independence measure (FIM) scores, length of stay (LOS), itemized hospital charges, discharge destination were main outcomes. RESULTS LOS was 13% longer and hospital charges were 12.5-18.0% higher in the very low Hct than remaining groups (p = 0.0001). The FIM score and subscores for walking, stair climbing, bathing, transfers, and dressing changes were comparable for all Hct groups for the overall score. Hct <30% did not correspond to worse outcomes in patients with bilateral surgeries compared with unilateral surgeries; total FIM scores improved 47-53% across all Hct groups, regardless of bilateral surgical status. Discharge to home ranged 92.6-94.7% across all Hct groups (p > 0.05). CONCLUSIONS Rehabilitation teams can expect comparable functional improvements and discharge to home in anemic and non-anemic patients with either unilateral or bilateral surgeries without hematologic correction in the rehabilitation setting, but might need an additional day to accomplish these outcomes.

Abstract
During the last decade there have been significant changes in the perioperative management of total hip replacement patients. This process begins in the preoperative phase. Many patients are much better informed and standardized preoperative patient programs improve patient outcome and optimize the clinical pathways. The techniques in perioperative pain management have also significantly improved. The surgeon should not only rely on the anesthesiologist but should also use the options available during surgery. Postoperative weight bearing is handled in a much more progressive way than previously. In a standard primary hip replacement pain-adapted full weight bearing is possible if there are no patient-specific problems. There has also been a shift in the postoperative capability of performing athletic or recreational activities. In general patients can perform those activities that were performed before the surgery, which also includes, for example downhill skiing.

Abstract
OBJECTIVE The Centers for Medicare and Medicaid Services (CMS) use a diagnostic category (revised in 2004) as one of eight criteria to determine whether a hospital is eligible for payment as an inpatient rehabilitation facility (IRF). Among the 13 specific categories of patients, there are three particular ones involving total knee arthroplasty (TKA) and hip arthroplasty (THA) patients. The purpose of this investigation was to analyze inpatient rehabilitation outcomes in TKA and THA patients, using these CMS criteria. DESIGN A multicenter, retrospective study using a consecutive patient sample from 15 independent inpatient rehabilitation facilities, conducted from January 1, 2002 through March 31, 2006. All patients had either primary or revision TKA or THA and were directly admitted for inpatient rehabilitation postacute care. Patients were 23,274 men and women, separated into three comparison pairs on the basis of CMS eligibility criteria: (1) unilateral or bilateral arthroplasty, (2) age <85 yrs or >or=85 yrs, or (3) body mass index (BMI) <50 or >or=50 kg/m2. All patients underwent a comprehensive rehabilitation program that included physical and occupational therapies for 3 hrs/day. Main outcomes were inpatient rehabilitation length of stay (LOS), functionality as assessed by the FIM instrument, FIM efficiency, hospital charges, and discharge disposition. RESULTS FIM efficiency scores were 8-21% lower in bilateral arthroplasties and patients aged >or=85 yrs, respectively (P < 0.0001). LOS was an average of 33% longer in patients >or=85 yrs than among patients <85 yrs (3.4 days; P < 0.0001). Total charges were 12-30% higher for patients with BMI >or=50 kg/m and >85 yrs than their comparative groups (P < 0.001). Arthroplasty patients <85 yrs were discharged more often to home compared with those >or=85 yrs (P = 0.0001). Patients >or=85 yrs were more likely to be transferred to a skilled nursing facility (7.4%) or back to acute care (3.9%) than those <85 yrs. CONCLUSIONS All arthroplasty patients demonstrated improved physical function after inpatient rehabilitation. Those aged >or=85 yrs demonstrated the lowest efficiency, the greatest cost, and were the least likely to return home.

Abstract
BACKGROUND The administration of tranexamic acid (TA) is associated with a decrease in the number of red blood cell (RBC) units transfused. However, concerns about its safety have hindered its broader use. STUDY DESIGN AND METHODS We evaluated the effect of TA on RBC transfusion and thromboembolic complications in total knee arthroplasty. We retrospectively studied 414 patients, 215 immediately before introducing TA treatment (control group) and after, in 199 patients without history of thromboembolic diseases (TA group). In a subgroup of patients, a lower extremities contrast venography was performed. RESULTS Fifty-four per cent of control group patients were transfused with RBC while only 17.6% of TA group patients received RBCs. In the TA that group, those transfused received less units (2.83 vs. 1.89), showed smaller mean calculated perioperative blood loss and haemoglobin values at discharge were higher compared to control group (10.1 vs. 9.3 g/dl). Thromboembolic complications were diagnosed in 2.8% of the patients in the control group and in 1.5% in the TA group. Asymptomatic distal deep venous thrombosis was found in 54 (14.8%) of TA group patients and 54 (30.1%) of control patients. TA administration reduced the expenditure for RBC transfusion plus the cost of TA from 148.94 to 33.87 euro per patient. CONCLUSION Routine administration of TA during total knee arthroplasty to patients without history of thromboembolic disease is associated with a 67% reduction in RBC transfusions and, in those transfused, with a reduction in the number of units administered. TA treatment was not associated with an increase in thromboembolic complications. Transfusion costs are significantly reduced.

Abstract
OBJECTIVE This multicenter study examined whether inpatient rehabilitation outcomes following total knee arthroplasty (TKA) were influenced by BMI. METHODS AND PROCEDURES This was a retrospective, comparative study conducted using a computerized medical database and medical records derived from TKA patients, at 15 independent rehabilitation hospitals (N = 5,428). Patients were separated into four groups based on BMI: non-obese (BMI < 25 kg/m(2)), overweight (25-29.9 kg/m(2)), moderately obese (30-40 kg/m(2)), severely obese (BMI > or = 40 kg/m(2)). All patients completed an interdisciplinary inpatient rehabilitation program post-TKA. Total and individual functional independence measure (FIM) scores, length of stay (LOS), FIM efficiency scores, itemized hospital charges, and discharge disposition location, were collected. RESULTS The percentage of total FIM change was 7.5% greater by the time of discharge in the non-obese than in the very severely obese (P < 0.05). FIM efficiency was lowest in the severely obese as compared to the remaining groups (3.7 points (pts)/day vs. 4.0-4.3 pts/day; P = 0.044). The change in the motor FIM score from admission to discharge was 6.7-15.6% greater in the non-obese than in the remaining groups (P < 0.05). The changes in cognition FIM, toilet transfer and walking without assistance scores were higher in the non-obese as compared to the severely obese group (P < 0.05). The severely obese group had higher total, physical and occupational therapy and pharmacy charges than the remaining groups (P < 0.05). DISCUSSION An excessive BMI does not prevent gains during inpatient rehabilitation; however, these gains are made less efficiently and at a higher cost than those made when the BMI is low.

Abstract
Compared with conventional total knee arthroplasty, rehabilitation after a minimally invasive procedure is faster. Flexion to 90 degrees is reached in a few days in most patients. Coordination exercises, stair climbing, and mobilisation with one or no crutches are achieved rapidly, and patients can usually return more quickly to their activities of daily living as well as professional and leisure-time activities. This progress is based on new surgical techniques that protect muscles and tendons. To optimize these results, analgaesia protocols and anaesthesia procedures could be improved, and rehabilitation programs should be individualised. Patient education is best started weeks before surgery because a well-motivated patient supports an excellent clinical outcome. New surgical techniques give us the possibility to think about routinely used perioperative procedures and improve them. The aim is to offer a concept of minimally invasive surgical technique and optimized protocols for perioperative anaesthesia, analgaesia, and rehabilitation.

Abstract
OBJECTIVE To examine admission hematocrit (Hct) status on inpatient rehabilitation outcomes after total knee (TKA) and hip arthroplasty (THA). DESIGN This study was a retrospective, exploratory analysis. Patients (n = 400) were stratified by admission hematocrit levels: normal (Hct >or=36-41%, World Health Organization criteria for normal Hct in women and men), low (Hct between the operational 30% cutoff and 36-41%), and very low (Hct <30%). Functional Independence Measure (FIM) scores and specific lower-body FIM motor scores, FIM efficiency, length of stay (LOS), and total hospital charges were analyzed. RESULTS Regardless of arthroplasty joint, all improved total FIM score, motor FIM score, and specific lower-body activity FIM scores (walking, wheelchair, dressing, transfers, stairs) by discharge (all P < 0.05). LOS was 28.9-31% longer in the TKA-very low Hct and THA-very low Hct groups than in the normal Hct groups (P = 0.026). Total hospital charges were 32.6-45.6% higher in the TKA-very low Hct and THA-very low Hct groups than in the normal Hct groups (P < 0.05). Hct was a significant contributor to the variance of linear regression models for LOS and total charges (P < 0.05). CONCLUSIONS Although very low Hct at admission does not impede functional gains, it is related to longer LOS and greater hospital charges. Rehabilitation teams should consider this when preparing plans of care, rehabilitation goals, and plans for discharge.
