Abstract
BACKGROUND Total knee replacements (TKRs) are successful operations that utilities several operative techniques including cruciate retaining (CR) and posterior stabilising (PS) prostheses. To date, neither approach has proved superior. Techniques and implants are under constant evolution and new trials are published. The purpose of this meta-analysis is to determine the current risks and benefits of these two approaches so that an up-to-date clinical recommendation can be given as to which approach if any is superior. METHODS We searched PubMed, Cochrane, Embase, Scopus, EBCSO, and Google Scholar. Risk of bias was assessed based on the Cochrane risk of bias criteria. Meta-analysisusing the random effects model was performed by the STATA software and results were displayed on forest plots. Sensitivity analysis was performed for possible causes of heterogeneity. RESULTS From 1164 studies, 15 eligible trials were included. Meta-analysis showed that the CR approach had significantly lower Range of Motion and HSS scores. There was no significant difference in KSS, OKS, VAS, or WOMAC scores. Blood loss was significantly less in the CR group. However, there was no significant difference in total complications or revisions. Sensitivity analysis did not reveal any differences in the results. CONCLUSION Despite inherent limitations, this updated meta-analysis suggests that both CR and PS approaches continue to be equivocal in terms of clinical outcomes. Both patients and surgeons can be confident in selecting either approach. LEVEL OF EVIDENCE Level I. SYSTEMATIC REVIEW REGISTRATION the protocol of this systematic review has been registered on PROSPERO. REGISTRATION NUMBER CRD42023391435.

Comparison of the effect of open-box versus closed-box prostheses on blood loss following total knee arthroplasty: a meta-analysis. Ann Med Surg (Lond) 2024; 86:1021-1028. [PMID: 38333267 PMCID: PMC10849461 DOI: 10.1097/ms9.0000000000001657] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/22/2023] [Accepted: 12/11/2023] [Indexed: 02/10/2024] Open
Abstract
Purpose Postoperative blood loss is a common complication following total knee arthroplasty (TKA). The authors aimed to analyze the significance of open versus closed-box prostheses in reducing blood loss after TKA. Methods PubMed, Cochrane, Scopus, and Web of Science were searched. Observational studies and clinical trials comparing the effect of open-box versus closed-box prostheses on blood loss following TKA were included. The primary outcome was total blood loss following TKA. Secondary outcomes included average transfused units and total operation time. Continuous data were represented as mean difference (MD) and CI, while dichotomous data were presented as odds ratio (OR) and CI. RevMan software version 5.4 was used to conduct the analysis. Results Four studies with a total number of 687 patients were included. The pooled analysis showed a statistically significant association between closed-box and decreased total blood loss following TKA compared with open-box (MD=173.19, 95% CI=88.77-257.61, P value <0.0001). Similar findings were reported in unilateral TKA (MD=190.63, 95% CI=70.91-310.35, P value=0.002), and bilateral TKA (MD=160.79, 95% CI=61.70-359.86, P value=0.001). There was no significant difference between open and closed-box regarding average transfused units (MD=0.02, 95% CI=-0.07-0.11, P value=0.68), blood transfusion rate (OR=1.38, 95% CI=0.85-2.26, P value=0.20), length of stay (MD=0.06, 95% CI=-0.27 to 0.38, P value=0.74), and total operation time (MD=1.08, 95% CI=-4.62 to 6.79, P value=0.71). Conclusion Closed-box reduces the total blood loss following unilateral and bilateral TKA. More studies are warranted to explore the benefits of Closed-box in patients with high bleeding susceptibility.

Better Flexion but Unaffected Satisfaction After Treatment With Posterior Stabilized Versus Cruciate Retaining Total Knee Arthroplasty - 2-year Results of a Prospective, Randomized Trial. J Arthroplasty 2024; 39:368-373. [PMID: 37598783 DOI: 10.1016/j.arth.2023.08.044] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/14/2023] [Revised: 08/09/2023] [Accepted: 08/11/2023] [Indexed: 08/22/2023] Open
Abstract
BACKGROUND Both the cruciate-retaining (CR) and posterior-stabilized (PS) implant systems are commonplace in modern total knee arthroplasty (TKA) practice. However, there is controversy regarding functional outcomes and survivorship. The aim of the underlying study was to evaluate differences between CR and PS TKA regarding knee function, patient-reported outcome measures (PROMs) as well as complication rates. METHODS 140 patients with knee osteoarthritis scheduled for an unconstrained TKA were enrolled in a prospective, randomized study. Patients received either a CR or PS implant. Range of motion and PROMs (Oxford Knee Score, Knee Society Score, European Quality of Life 5 Dimensions 3 Level, University of California Los Angeles Activity scale and subjective satisfaction) were assessed prior to, 3 months, 1 and 2 years after surgery. RESULTS We found minor differences between treatment groups regarding demographic factors. Within the PS group duration of surgery was longer (mean PS 81.4 min vs CR 76.0 min, P = .006). We observed better flexion (median PS 120.0° vs CR 115°, P = .017) and an overall better range of motion (median PS 120.0° vs CR 115.0°, P = .008) for the PS group. PROMs did not differ between groups. At 2-year follow-up there were no revisions in either cohort. Five patients needed reoperations. Three patients needed manipulation under anesthesia, 2 in the CR and one in the PS group. CONCLUSION While PS TKA achieved a better flexion capability, PROMs were similar in CR and PS TKA. The CR implant design continues to be a reliable option for patients with an intact posterior cruciate ligament.

[PMID: 37510685 PMCID: PMC10380423 DOI: 10.3390/jcm12144570] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/07/2023] [Revised: 07/06/2023] [Accepted: 07/07/2023] [Indexed: 07/30/2023] Open
Abstract
The transfusion rate in staged bilateral total knee arthroplasty (TKA) remains high despite the application of blood management techniques. The potential of robotic arm-assisted TKA (R-TKA) in reducing the transfusion rate in staged bilateral surgery has not yet been investigated. Therefore, we aimed to evaluate the effectiveness of R-TKA on transfusion reduction compared with conventional TKA (C-TKA) in staged bilateral surgery. This retrospective study involved two groups of patients who underwent 1-week interval staged bilateral TKA-the C-TKA group and the R-TKA group-using MAKO SmartRobotics (Stryker, Kalamazoo, MI, USA). Each group comprised 53 patients after propensity score matching and was compared in terms of nadir hemoglobin (Hb) level and transfusion rate after each stage of surgery. Both groups showed no significant differences in the propensity-matched variables of age, sex, body mass index, American Society of Anesthesiologists physical status score, and preoperative Hb level. The R-TKA group showed a significantly higher nadir Hb level than the C-TKA group after the second TKA (p = 0.002). The transfusion rate was not significantly different between the two groups after the first TKA (p = 0.558). However, the R-TKA group showed a significantly lower transfusion rate in the TKA (p = 0.030) and overall period (p = 0.023) than the C-TKA group. Patients who undergo staged bilateral R-TKA have lower transfusion rate than those who undergo C-TKA. R-TKA may be effective in minimizing unnecessary allogeneic transfusions in staged bilateral surgery.

Abstract
PURPOSE This study aimed to conduct a systematic review of the recent research output to present more evidence of the current clinical applications of wearable sensors to determine the change and the recovery in gait function pre- and post-total knee arthroplasty (TKA). METHODS A systematic search of the PubMed, ScienceDirect, and Scopus databases was conducted in October 2022. Inclusion criteria consisted of applying acceleration wearable sensors for pre- and post-arthroplasty assessment of the gait cycle. Studies reporting gait analysis using wearable sensors in patients with knee osteoarthritis at any time after total or partial knee arthroplasty (KA) were also included. Each included study was assessed using the Joanna Briggs Institute Critical Appraisal Tool for Quasi-Experimental studies. RESULTS Twelve articles were finally considered. The extracted data included essential characteristics of participants, KA studies and their characteristics, sensor technology characteristics and the clinical protocols, gait parameter changes, and various clinical outcome scores at different follow up times after KA. Postoperative examinations were performed from 5 days to 1 year after KA. Clinical outcome scores and gait variables for all patient groups, with or without postoperative rehabilitation, showed various recovery profiles. A variety of wireless sensor devices for gait analysis were recorded. Also, different types of KA were found in the studies. CONCLUSIONS The study's findings showed that acceleration-based gait analysis has notable clinical use in monitoring patients after KA. This application provides objective information on the functional outcome beyond the use of clinical outcome scores. More extensive prospective studies are required to investigate gait function further with the help of wearable sensors in patients with knee osteoarthritis.

Abstract
» Bilateral total knee arthroplasty (BTKA) is an effective surgical treatment for bilateral knee arthritis and can be performed as a simultaneous surgery under a single anesthetic setting or as staged surgeries on separate days. » Appropriate patient selection is important for simultaneous BTKA with several factors coming into consideration such as age, comorbidities, work status, and home support, among others. » While simultaneous BTKA is safe when performed on appropriately selected patients, current evidence suggests that the risk of complications after simultaneous BTKA remains higher than for staged BTKA. » When staged surgery is preferred, current evidence indicates that complication risks are minimized if the 2 knees are staged at least 3 months apart. » Simultaneous BTKA is the economically advantageous treatment option relative to staged BTKA, primarily because of shorter total operative time and total hospital stay.

Abstract
OBJECTIVES The aim of this study was to compare the smartphone- based gait analysis data of patients who underwent total knee arthroplasty (TKA) and unicompartmental knee arthroplasty (UKA). PATIENTS AND METHODS Between January 2016 and April 2019, a total of 51 patients (3 males, 48 females; mean age: 60.92 years; range, 51 to 70 years) who were operated with UKA or TKA in our clinic were retrospectively analyzed. The patients were divided into two groups according to the type of procedure as the UKA group (n=17) and unilateral TKA group (n=34). Gait analysis was made via a smartphone application (Gait Analyzer software version 0.9.95.0) with data acquired from the accelerometer of the smartphone. This analysis was performed using data collected from the Acceleration Sensor LSM6DSO into the Samsung Galaxy Note 10 Plus phone. Gait velocity, step time, step length, cadence, step time symmetry, step length symmetry, and vertical COM (vert-COM) parameters were measured. RESULTS There were no statistically significant differences between the groups in respect of age, sex, body mass index, operated side, and follow-up duration. Compared to the TKA group, the UKA patients showed a better gait pattern in gait velocity (p=0.03), step time symmetry (p=0.005), and step length symmetry (p=0.024). No significant difference was detected in step time (p=0.807), step length (p=0.302), cadence (p=0.727) and vert-COM parameters (p=0.608). CONCLUSION The gait of UKA patients is closer to the physiological pattern with a better gait velocity, step time symmetry, and step length symmetry than TKA patients. The surgical treatment option of UKA for knee medial compartment osteoarthritis leads to a better gait pattern than TKA.

Abstract
PURPOSE Concerning the ongoing debate on the effects of continuing aspirin therapy on blood loss in knee arthroplasty, we conducted a retrospective investigation to test the hypothesis that continuation of aspirin prior total knee arthroplasty (TKA) will not cause more blood loss. METHODS From a database of patients who underwent unilateral TKA between 2011 and 2016, we identified two groups: the aspirin group (patients continued aspirin during perioperative period) and the nonaspirin group (patients had no current or recent history of aspirin usage). We extracted and compared patient demographic information, comorbidity index, baseline serum hemoglobin (Hb), and creatinine level between the two groups. We also compared our primary outcomes, including the total blood loss, transfusion requirement, and length of hospitalization between the two groups. A multivariate logistic regression for analyzing the risk factors of requiring transfusion was performed. RESULTS We found that apart from preoperative serum creatinine level, there was no difference in the baseline Hb level, perioperative change in Hb, total blood loss, or length of hospitalization between the two groups. The percentage of transfusion utilization was also comparable between the two groups. Our regression analysis shows that the risk of requiring transfusion after TKA is not significantly associated with patients taking aspirin therapy before operation. CONCLUSION Patients who underwent TKA with continuation of low-dose aspirin did not result in more blood loss. Current blood loss management has provided sufficient reduction of blood loss to accommodate aspirin therapy perioperatively. We suggest that it is safe to continue aspirin prior to TKA.

The Effect of Prosthesis Design on Blood Loss in Simultaneous Bilateral Total Knee Arthroplasty: Closed-Box versus Open-Box Prosthesis. Clin Orthop Surg 2019; 11:409-415. [PMID: 31788163 PMCID: PMC6867911 DOI: 10.4055/cios.2019.11.4.409] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/23/2018] [Accepted: 03/25/2019] [Indexed: 01/13/2023] Open
Abstract
Background Various pre- and perioperative risk factors have been reported in association with blood loss in knee arthroplasty. However, the effect of the uncovered cancellous surface on blood loss in simultaneous bilateral total knee arthroplasty (SBTKA) by different prosthetic designs is not well elucidated. Therefore, this study aimed to compare the blood loss and transfusion rate between different knee prostheses in SBTKA and to identify risk factors that influence blood loss and transfusion after SBTKA. Methods Demographic and perioperative data of patients who underwent SBTKA using either a closed-box or an open-box femoral component of posterior-stabilized fixed-bearing (PS FB) knee system were retrospectively reviewed. The calculated blood loss (CBL) and blood transfusion rate were compared by using Student t-test and confirmed with multivariate regression analysis. Results There was no significant difference in preoperative parameters between 54 closed-box and 56 open-box PS FB TKAs. The CBL of the closed-box TKA group was 135.23 mL less (95% confidence interval [CI], −215.30 to −55.16; p = 0.001) than that of the open-box TKA group. However, the blood transfusion rates of the closed- and open-box TKA groups were not significantly different (24.1% and 38.5%, p = 0.11). For each additional minute of total operative time, 3.75 mL (95% CI, 1.75 to 5.76; p < 0.001) of blood loss was anticipated. For each additional mg/dL of preoperative hemoglobin, 71% (p < 0.001) reduction of blood transfusion probability was predicted. Conclusions The use of closed- and open-box knee prostheses resulted in a significant difference in blood loss in SBTKA. Prolonged operative time also significantly increased CBL. Therefore, strategies to control the bleeding surface and shorten operative duration may be considered if blood loss is of special concern. The preoperative hemoglobin was the only factor that affects the probability of blood transfusion in SBTKA.

Blood loss reduction: effect of different knee prosthesis designs and use of tranexamic acid-a randomized controlled trial. EUROPEAN JOURNAL OF ORTHOPAEDIC SURGERY AND TRAUMATOLOGY 2019; 29:1519-1524. [PMID: 31119383 DOI: 10.1007/s00590-019-02450-2] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/25/2018] [Accepted: 05/17/2019] [Indexed: 01/16/2023]
Abstract
PURPOSE In regard to blood loss in total knee arthroplasty (TKA), the effect of either knee prosthesis designs or bone preparation is still unclear. While the benefit of using tranexamic acid (TXA) is well demonstrated, our study aims to determine the effect of different knee prosthesis designs uses and efficacy of blood loss reduction by different routes of TXA administration. METHODS The 228 patients undergone primary TKA were randomized to determine between open-box and closed-box prosthesis. Among each group, a second randomization was applied to categorize the patients into (1) no use of TXA (No-TXA), (2) intra-articular TXA use (IA-TXA) and (3) intravenous TXA use (IV-TXA). The calculated blood loss (CBL), drain volume (DV) and an average number of units of blood transfused (ANUBT) were blindly evaluated. RESULTS The open-box TKA had 85.60 and 63.29 ml (p = 0.02 and p < 0.01) more CBL and DV compared to closed-box TKA. The IA-TXA and IV-TXA significantly reduced CBL by 190.75 and 162.01 ml (p < 0.01 and p < 0.01) and reduced DV by 129.07 and 61.04 ml (p < 0.01 and p = 0.01), respectively, when compared to No-TXA. Patients who received IA and IV-TXA had ANUBT of 0.21 and 0.23 unit, which was significantly lower than 0.42 unit of No-TXA group (p = 0.03). CONCLUSIONS Use of the different prosthesis designs could significantly affect CBL and DV following TKA. However, the use of either design resulted in a comparable ANUBT. Regardless of prosthetic type, either IA- or IV-TXA could significantly reduce the CBL and ANUBT when compared to No-TXA.

Abstract
AIM A meta-analysis comparing the outcomes of patients undergoing cruciate retaining (CR) versus posterior stabilized (PS) in primary total knee arthroplasty was performed. The outcomes of interest were the Knee Society Rating System, clinical (KSCS) and functional (KSFS) subscales, joint range of motion (ROM), surgical duration and further complications (anterior knee pain, instability and revision rate). MATERIALS AND METHODS The search was conducted in July 2018, accessing the following databases: Cochrane Systematic Reviews, Scopus, PubMed, EMBASE, CINAHL, AMED and Google Scholar. We included only clinical trials level of evidence I and II. During the statistical analysis, we excluded all the studies that affect negatively the I2 test, in order to achieve more reliable results. For the methodological quality assessment we referred to the PEDro score. The risk of publication's bias was evaluated by the funnel plots across all the comparisons. RESULTS The PEDro score reported a good methodological quality assessment. The funnel plot detected a very low risk of publication's bias. We included in this study 36 articles, counting a total of 4052 patients and 4884 procedures. The mean follow-up term for both groups was 3.39 years. The ROM resulted in an overall estimate effect of 2.18° in favor of the PS group. The overall WOMAC showed a result in favor of the PS group. The overall estimate effect of the KSCS was 0.02% higher in the CR group. The KSFS showed an overall estimate effect of 2.09% in favor of the PS group. Concerning the surgical duration, the estimate effect resulted in 6.87 min shorter in the CR group. No differences were reported across the two groups regarding anterior knee pain, knee joint instability or revision rate. CONCLUSION Both the prosthetic implants provided to be a safety and feasible solution to treat end-stage knee joint degeneration. The PS implants reported improvements in the knee range of motion and a prolongation of the surgical time. No clinically relevant dissimilarities concerning the analyzed scores were evidenced. No statistically significant relevant differences in complications were detected.

Abstract
BACKGROUND Controversy continues regarding whether the posterior cruciate ligament should be retained or removed during total knee arthroplasty (TKA) procedure. The objective was to compare the clinical outcomes with a minimum follow-up of 10 years between patients who received contemporary cruciate-retaining or posterior-stabilized primary TKA. METHODS Case-control study of 268 patients who underwent cruciate-retaining TKA vs 211 to posterior-stabilized design, with the same arthroplasty system, and a minimum follow-up of 10 years. Clinical assessment was performed by Knee Society scores, Western Ontario and MacMasters Universities and Short-Form 12 questionnaires, range of motion, and patient satisfaction. RESULTS Successful outcomes were found for both designs. No significant differences in functional scores, range of motion, patient-related scores, or patient satisfaction. Between the 5-year and last postoperative follow-up, there were a significant decrease of all clinical scores in both groups. In addition, complication rate and implant survival were similar between groups. CONCLUSION The superiority of one design over the other was not found. Both designs can be used expecting long-term successful outcomes and high survival. The choice of the design depended on the status of the posterior cruciate ligament and surgeon preference.

Abstract
BACKGROUND Effective blood management strategies are a major determinant of successful outcomes after one-stage bilateral total knee arthroplasty (BTKA). Proper patient selection with preoperative optimization and intra- and postoperative interventions can reduce transfusion risk and associated morbidity in these patients. QUESTIONS/PURPOSES The purpose of this study was to evaluate intraoperative blood management modalities based on three keystone questions: (1) What is the role of the anesthesiologist?, (2) Which are the surgeon-dependent strategies?, and (3) Is there any place for pharmacologic interventions? METHODS We searched the established electronic literature database MEDLINE. After critical appraisal, 94 studies were deemed eligible from which to draw documented evidence. RESULTS A number of blood-conserving methods are currently implemented in patients undergoing one-stage BTKA. Among them, regional anesthesia, tourniquet use, and tourniquet deflation after wound closure, femoral canal sparing or femoral canal plugging, avoidance of drains, and tranexamic acid use were the intraoperative strategies with documented efficacy in blood conservation. CONCLUSION Combined proper intraoperative anesthesiologic, surgical, and pharmacologic interventions reduce blood loss and need for transfusion in BTKA patients. However, contemporary relevant literature is lacking evidence-based guidelines.

The combined use of oral and topical tranexamic acid is a safe, efficient and low-cost method in reducing blood loss and transfusion rates in total knee arthroplasty.

Abstract
AIMS The combined (IV (intravenous) + topical) use of tranexamic acid (TXA) has been shown to be a safe method and more effective than single (IV or topical) application. The optimal administration method of TXA is still being investigated and safety, efficiency and cost are the three main crucial parameters in achieving the best administration method. We aimed to determine whether combined (oral + topical) use of TXA reduced blood loss and transfusion rates more than single (topical) administration in TKA and whether oral + topical use is as safe and efficient as the IV + topical use, in addition to the main advantage of relatively low cost. METHODS In this prospective, randomized study, 100 patients were randomly assigned to either the topical TXA group or the combined (oral + topical) TXA group. There were no significant differences between the groups in age, body mass index or gender. The haemoglobin and haematocrit levels of each patient were recorded preoperatively and on post-operative days 0, 1, 2 and 3. The post-operative suction drainage and blood transfusion volumes were also recorded. RESULTS There were statistically significant differences between the groups in haemoglobin and haematocrit levels on post-operative days 0, 1, 2 and 3 ( p < 0.05) in favour of the combined group. The post-operative drainage amounts ( p = 0.0001), measured blood loss volume ( p = 0.003) and transfusion rates ( p = 0.03) were lower in the combined (oral + topical) group compared to the topical group. CONCLUSIONS Of the different methods of TXA administration, the combined use of oral and topical TXA is a safe, efficient and low-cost method in reducing blood loss and transfusion rates after TKA.

Abstract
INTRODUCTION Posterior-stabilized (PS) and cruciate-retaining (CR) total knee arthroplasties (TKA) are both successfully used for treatment of end-stage osteoarthritis. The choice of constraint depends on knee deformity and stability as well as most importantly surgeon preference. The aim of this study was to compare the amount of blood loss and required transfusions following TKA with the two different designs. MATERIALS AND METHODS In a retrospective approach, 473 patients undergoing TKA were included (240 CR and 233 PS from a single manufacturer). Demographics at base line were comparable between both groups. Blood loss [red blood cell (RBC) loss] was calculated after documentation of pre- and postoperative hematocrit levels at discharge. Transfusion requirements were recorded. Statistical analysis was done using Mann-Whitney U test. RESULTS The calculated blood loss (RBC loss) at discharge was 548 ± 216 ml in the PS group compared with 502 ± 186 ml in the CR group (p = 0.032). There were no differences in the transfusion requirements between both groups (PS 0.41 vs. CR 0.37, p = 0.39). DISCUSSION The blood loss was significantly higher in the PS group. This may be due to the box preparation that exposes more cancellous femoral bone, which may add to postoperative bleeding. The differences remain, however, small, as they did not lead to a significantly higher transfusion rate with PS TKA.

Abstract
AIMS Anesthetic technique affects perioperative outcomes, but less was known in simultaneous bilateral total knee arthroplasty (BTKA). A single center, retrospective analysis was carried out to prove the hypothesis that utilization of regional anesthesia would result in favorable perioperative outcomes. METHODS Medical records of patients admitted for simultaneous BTKA between 2004 and 2013 were analyzed. Two groups, the general anesthesia (GA) and regional anesthesia (RA) group, were identified. Patient preoperative characteristics were compared. Perioperative outcomes measured included blood loss, transfusion requirement, length of hospitalization, operating time, and 30-day perioperative complications. RESULTS A total of 513 patients were identified, 54.6% were performed under GA, and 45.4% under RA. Patient characteristics were similar between the two groups, except that patients operated under GA were younger than those under RA. RA was associated with significantly less perioperative blood loss (981 vs. 1075 mL, p = 0.017) and 30-day complications (6.4 vs. 13.2%, p = 0.016). Systemic and organ specific infections were particularly lower in the RA group (0.4 vs. 3.9%, p = 0.009). Transfusion requirement, length of hospitalization, and operating time were similar between the two groups. After correcting for covariates, RA offered a 92 mL (p = 0.023) reduction in blood loss and 49% less overall complications (p = 0.047), compared to GA. CONCLUSION Patients who underwent simultaneous BTKA under RA had lesser blood loss and lower complication rate than GA. The impact of RA can be further exploited to improve perioperative outcomes of simultaneous BTKA in addition to various other interventions.

Abstract
BACKGROUND AND PURPOSE To retain or to sacrifice the posterior cruciate ligament (PCL) in total knee arthroplasty (TKA) remains a matter of discussion. In this systematic review, we wanted to find differences in functional and clinical outcome between the 2 methods. METHODS We conducted a systematic review and meta-analysis including all randomized controlled trials (RCTs) and quasi-RCTs that have compared PCL retention with PCL sacrifice in TKA with a minimum of 1-year follow-up. Primary outcome was range of motion. Secondary outcomes were knee pain and clinical scoring systems that were preferably validated. Quality of evidence was graded using the GRADE approach. All outcomes available for data pooling were used for meta-analysis. RESULTS 20 studies involving 1,877 patients and 2,347 knees were included. In meta-analysis, the postoperative flexion angle had a mean difference of 2 degrees (95% CI: 0.23-4.0; p = 0.03) and the KSS functional score was 2.4 points higher in favor of PCL sacrifice (95% CI: 0.41-4.3; p = 0.02). There were no statistically significant differences regarding other measured clinical outcomes such as WOMAC, KSS pain, clinical and overall score, HSS score, SF-12, radiolucencies, femoro-tibial angle, and tibial slope. The quality of the studies varied considerably. Risk of bias in most studies was unclear; 5 were judged to have a low risk of bias and 5 to have a high risk of bias. INTERPRETATION We found no clinically relevant differences between retention and sacrifice of the PCL in TKA, in terms of functional and clinical outcomes. The quality of the studies ranged from moderate to low. Based on the current evidence, no recommendation can be made as to whether to retain or to sacrifice the PCL.
