Profound Properties of Protein-Rich, Platelet-Rich Plasma Matrices as Novel, Multi-Purpose Biological Platforms in Tissue Repair, Regeneration, and Wound Healing. Int J Mol Sci 2024; 25:7914. [PMID: 39063156 PMCID: PMC11277244 DOI: 10.3390/ijms25147914] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/26/2024] [Revised: 07/07/2024] [Accepted: 07/17/2024] [Indexed: 07/28/2024] Open
Abstract
Autologous platelet-rich plasma (PRP) preparations are prepared at the point of care. Centrifugation cellular density separation sequesters a fresh unit of blood into three main fractions: a platelet-poor plasma (PPP) fraction, a stratum rich in platelets (platelet concentrate), and variable leukocyte bioformulation and erythrocyte fractions. The employment of autologous platelet concentrates facilitates the biological potential to accelerate and support numerous cellular activities that can lead to tissue repair, tissue regeneration, wound healing, and, ultimately, functional and structural repair. Normally, after PRP preparation, the PPP fraction is discarded. One of the less well-known but equally important features of PPP is that particular growth factors (GFs) are not abundantly present in PRP, as they reside outside of the platelet alpha granules. Precisely, insulin-like growth factor-1 (IGF-1) and hepatocyte growth factor (HGF) are mainly present in the PPP fraction. In addition to their roles as angiogenesis activators, these plasma-based GFs are also known to inhibit inflammation and fibrosis, and they promote keratinocyte migration and support tissue repair and wound healing. Additionally, PPP is known for the presence of exosomes and other macrovesicles, exerting cell-cell communication and cell signaling. Newly developed ultrafiltration technologies incorporate PPP processing methods by eliminating, in a fast and efficient manner, plasma water, cytokines, molecules, and plasma proteins with a molecular mass (weight) less than the pore size of the fibers. Consequently, a viable and viscous protein concentrate of functional total proteins, like fibrinogen, albumin, and alpha-2-macroglobulin is created. Consolidating a small volume of high platelet concentrate with a small volume of highly concentrated protein-rich PPP creates a protein-rich, platelet-rich plasma (PR-PRP) biological preparation. After the activation of proteins, mainly fibrinogen, the PR-PRP matrix retains and facilitates interactions between invading resident cells, like macrophages, fibroblast, and mesenchymal stem cells (MSCs), as well as the embedded concentrated PRP cells and molecules. The administered PR-PRP biologic will ultimately undergo fibrinolysis, leading to a sustained release of concentrated cells and molecules that have been retained in the PR-PRP matrix until the matrix is dissolved. We will discuss the unique biological and tissue reparative and regenerative properties of the PR-PRP matrix.

Abstract
PURPOSE To evaluate and synthesize the available literature related to platelet-rich plasma (PRP) treatment of knee pathologies and to provide recommendations to inform future research in the field. METHODS PubMed, CINAHL, and Scopus databases were queried on October 6, 2023. All identified citations were collated and uploaded into Covidence for screening and data extraction. Studies were included if they were human studies published in English with adult cohorts that received PRP as a procedural injection or surgical augmentation for knee pathologies with patient-reported outcome measures (PROMs) and level of evidence Levels I-IV. RESULTS Our search yielded 2,615 studies, of which 155 studies from 2006 to 2023 met the inclusion criteria. Median follow-up was 9 months (±11.2 months). Most studies (75.5%) characterized the leukocyte content of PRP, although most studies (86%) did not use a comprehensive classification scheme. In addition, most studies were from Asia (50%) and Europe (32%) and were from a single center (96%). In terms of treatment, 74% of studies examined PRP as a procedural injection, whereas 26% examined PRP as an augmentation. Most studies (68%) examined treatment of knee osteoarthritis. Many studies (83%) documented significant improvements in PROMs, including 93% of Level III/IV evidence studies and 72% of Level I/II evidence studies, although most studies (70%) failed to include minimal clinically important difference values. The visual analog scale was the most-used PROM (58% of studies), whereas the Short Form Health Survey 36-item was the least-used PROM (5% of studies). CONCLUSIONS Most published investigations of knee PRP are performed in Asia, investigate procedural injection for osteoarthritis, and show significant outcome improvements. In addition, this review highlights the need for better classification of PRP formulations. LEVEL OF EVIDENCE Level IV, scoping Review of level I-IV studies.

Abstract
Background Modified Broström-Gould (MBG) surgery is frequently used for chronic lateral ankle instability (CLAI). However, conventional postoperative management (CPOM) due to prolonged immobilization may have adverse effects on tendons, ligaments, and joints, causing stiffness. This prospective, randomized controlled trial aimed to determine outcomes among patients randomized to receive CPOM plus ultrasonography-guided triple injections of leukocyte-rich platelet-rich plasma (LR-PRP) compared to patients who receive only CPOM after MBG surgery. Methods The present study included 40 patients with symptomatic CLAI who were candidates for the MBG surgery. The patients were randomized into 2 groups of 20, the control and PRP groups. In the PRP group, patients were injected with 3 doses of LR-PRP solution using ultrasonographic guidance. In the first injection, 2 mL of LR-PRP was injected near the injury site, and in the second and third injections, 4 mL of LR-PRP was injected in the tibiotalar joint. All patients received a short leg splint for 2 weeks, followed by 4 weeks in a walking boot. The primary outcome measure was the visual analog scale (VAS), and the secondary outcome measures were the American Orthopaedic Foot & Ankle Society (AOFAS) ankle-hindfoot scale and ankle total range of motion (total ROM). The assessment was performed at baseline and 3 and 6 months after surgery. Results The mean VAS and AOFAS scores improved significantly in both groups 6 months after surgery (P < .001). However, the PRP group did not significantly improve in VAS or AOFAS scores compared with the control group. No clinically significant difference was observed between the 2 groups regarding the total ROM scores at month 3. Conclusion The application of LR-PRP after MBG surgery did not show any superior clinical or functional improvement over CPOM. Level of Evidence Level II, prospective randomized trial.

Effectiveness of intradiscal platelet rich plasma for discogenic low back pain without Modic changes: A randomized controlled trial. INTERVENTIONAL PAIN MEDICINE 2022; 1:100011. [PMID: 39238810 PMCID: PMC11373021 DOI: 10.1016/j.inpm.2022.100011] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 11/17/2021] [Revised: 01/11/2022] [Accepted: 01/11/2022] [Indexed: 09/07/2024]
Abstract
Objective To determine if autologous platelet-rich plasma (PRP) injection into a degenerative intervertebral disc, without Modic changes on magnetic resonance imaging (MRI), improve pain and function. Design Prospective, randomized controlled study. Setting Outpatient spine practice (Stichting Rugpoli, Netherlands). Participants Adults with chronic low back pain referred to Stichting Rugpoli, according to the Dutch General Practitioners Guidelines, unresponsive to conservative treatment, without Modic changes on MRI. Methods Provocation discography was performed to confirm the suspected disc was the source of pain. Participants were randomized to receive 1.0 cc intradiscal PRP (intervention) or 1.0 cc Saline with 0.2g Kefzol (control). Data on pain (Numeric Rating Scale), physical function (Roland Morris Disabilty Questionnaire, RMDQ), and participants' general perceived health (SF-12) were collected at 1 week, 4 weeks, 2 months, 6 months, 9 months and 1 year. A repeated-measures analysis (mixed model) was used for comparing the outcomes of the groups. Results Of the initial 98 (49 intervention, 49 control) patients randomized, 89 (91%) (44 intervention, 45 control) with complete outcome data were analyzed. Groups were balanced at baseline. After twelve months no differences between groups were found in the average pain (improved 21/44 in intervention vs 16/45 in control, p = 0.244), the disability scores (RMDQ minimal 3 points improvement 22/44 in intervention vs 24/45 in control, p = 0.753) and the SF-12 (mean difference physical health -1.19, 95% CI -5.39 to 2.99, p = 0.721, and mental health -0.34, 95% CI -3.99 to 3.29, p = 0.834). One serious adverse event occurred (spondylodiscitis) after intervention. Conclusion Participants who received intradiscal PRP showed no significant improvement in pain or functionality compared to the control group at 1 year follow up.

Abstract
One of the most severe effects of coronavirus disease 2019 (COVID-19) is lung disorders such as acute respiratory distress syndrome. In the absence of effective treatments, it is necessary to search for new therapies and therapeutic targets. Platelets play a fundamental role in respiratory disorders resulting from viral infections, being the first line of defense against viruses and essential in maintaining lung function. The direct application of platelet lysate (PL) obtained from the platelet-rich plasma of healthy donors could help in the improvement of the patient due its anti-inflammatory, immunomodulatory, antifibrotic, and repairing effects. This work evaluates PL nebulization by analyzing its levels of growth factors and its biological activity on lung fibroblast cell cultures, besides describing a scientific basis for its use in this kind of pathology. The data of the work suggest that the molecular levels and biological activity of the PL are maintained after nebulization. Airway administration would allow acting directly on the lung tissue modulating inflammation and stimulating reparative processes on key structures such as the alveolocapillary barrier, improving the disease and sequels. The protocol developed in this work is a first step for the study of nebulized PL both in animal experimentation and in clinical trials.

Perioperative Selective Serotonin Reuptake Inhibitor Use Is Associated With an Increased Risk of Transfusion in Total Hip and Knee Arthroplasty. J Arthroplasty 2019; 34:2898-2902.

Abstract
BACKGROUND Selective serotonin reuptake inhibitors (SSRIs) have been shown in both orthopedic and general surgery literature to be associated with an increased risk of blood loss, and this is thought to occur via diminished platelet serotonin reuptake and subsequent decline in platelet aggregation potential. In this study, we aim at quantifying the effect of treatment with SSRIs on blood loss and transfusion rates following total hip (THA) or total knee arthroplasty (TKA). METHODS THA (4485) and TKA (5584) cases from January 2013 to December 2017 at the investigating institution were queried and analyzed separately from an institutional database. Patients were stratified by utilization of an SSRI at the time of surgery. Patient demographics, baseline coagulopathy, preoperative and postoperative hemoglobin, transfusion, and length of stay were obtained to compare the 2 cohorts. RESULTS The transfusion rate for SSRI users was 3.9% in the TKA group and 8.5% in the THA group. After controlling for age, gender, body mass index, presence of coagulopathy, procedure (THA vs TKA), and SSRI status, SSRI utilization was significantly associated with increased blood loss (P < .004), and logistic regression controlling for the same variables showed SSRI utilization to be predictive of transfusion (odds ratio, 1.476; P < .001). CONCLUSION SSRI utilization was associated with increased perioperative blood loss and predictive of transfusion risk, particularly with THA. This represents an important factor that may be modified in the setting of total joint arthroplasty but further work will be necessary to study potential alternative medications for depression in the perioperative phase.

Abstract
BACKGROUND Stiffness is a common reason for suboptimal clinical outcomes after primary total knee arthroplasty (pTKA). There is a lack of consensus regarding its definition, which is often conflated with its histopathologic subcategory-i.e., arthrofibrosis. There is value in refining the definition of acquired idiopathic stiffness in an effort to select for patients with arthrofibrosis. We conducted a systematic review and meta-analysis to establish a consensus definition of acquired idiopathic stiffness, determine its prevalence after pTKA, and identify potential risk factors for its development. METHODS MEDLINE, Embase, Cochrane Controlled Register of Trials (CENTRAL), and Scopus databases were searched from 2002 to 2017. Studies that included patients with stiffness after pTKA were screened with strict inclusion and exclusion criteria to isolate the subset of patients with acquired idiopathic stiffness unrelated to known extrinsic or surgical causes. Three authors independently assessed study eligibility and risk of bias and collected data. Outcomes of interest were then analyzed according to age, sex, and body mass index (BMI). RESULTS In the 35 included studies (48,873 pTKAs), the mean patient age was 66 years. In 63% of the studies, stiffness was defined as a range of motion of <90° or a flexion contracture of >5° at 6 to 12 weeks postoperatively. The prevalence of acquired idiopathic stiffness after pTKA was 4%, and this did not differ according to age (4%, I = 95%, among patients <65 years old and 5%, I = 96%, among those ≥65 years old; p = 0.238). The prevalence of acquired idiopathic stiffness was significantly lower in males (1%, I = 85%) than females (3%, I = 95%) (p < 0.0001) as well as in patients with a BMI of <30 kg/m (2%, I = 94%) compared with those with a BMI of ≥30 kg/m (5%, I = 97%) (p = 0.027). CONCLUSIONS Contemporary literature supports the following definition for acquired idiopathic stiffness: a range of motion of <90° persisting for >12 weeks after pTKA in patients in the absence of complicating factors including preexisting stiffness. The mean prevalence of acquired idiopathic stiffness after pTKA was 4%; females and obese patients were at increased risk. LEVEL OF EVIDENCE Therapeutic Level IV.

Abstract
Patients who undergo total hip arthroplasty (THA) may experience a large amount of blood loss. The objective of our study is to include randomized controlled trials (RCTs) and compare the clinical outcomes of fibrin sealant (FS) versus placebo after a THA. In October 2015, we searched the following databases: Medline, Embase, PubMed, the Cochrane Controlled Trials Register, Web of Science, the China National Knowledge Infrastructure, the China Wanfang database and Google Scholar. Finally, seven studies that included 679 patients met the inclusion criteria. The meta-analysis indicated that the topical administration of FS was associated with a reduction of the need for transfusion compared to the control group (P = 0.05). And topical FS will reduce total blood loss after THA (P = 0.0003) and blood loss in drainage (P = 0.002). However, there was no significant difference in terms of the intraoperative blood loss (P = 0.62) and the rate of deep venous thrombosis (DVT), fever, pain, anemia, hematoma and oozing. In conclusion, the use of FS in patients who are undergoing THA may reduce perioperative blood loss and attenuate the decrease in Hb. Furthermore, FS do not decrease the intraoperative blood loss without an increase in the risk of postoperative DVT, fever, pain, anemia, hematoma and oozing.

Abstract
PURPOSE The aim of the present study was to assess the efficacy of a thrombin-based topical haemostatic in reducing blood requirements after total knee replacement (TKR) revision surgery. METHODS This prospective, randomized, controlled study was designed to evaluate the haemostatic efficacy and safety of a thrombin-based topical haemostatic (Floseal) versus standard treatment in patients receiving total knee revision arthroplasty. The decrease in haemoglobin values postsurgery and the blood units transfused were recorded. The decision to transfuse was made by a surgeon blinded to the patient's group allocation. RESULTS Forty-eight patients were enroled in the study; twenty-four patients each were randomized to the treatment and control groups, respectively. The median decrease in haemoglobin concentration on the first postoperative day was 2.2 g/dL in the treatment group and 2.7 g/dL in the control group. A significant reduction in units of blood transfused was also observed in the treatment group compared with the control group [1.1 ± 1.13 (range 0-4) vs. 1.9 ± 1.41 (range 0-5) blood units; P = 0.04]. No major treatment-related adverse events were recorded in the study. CONCLUSIONS This study shows that a thrombin-based topical haemostatic reduces the need for blood transfusion in TKR revision surgery. CLINICAL RELEVANCE A thrombin-based topical haemostatic agent can be an appropriate solution to enhance haemostasis and vessel sealing at the operative site in TKR revision surgery, in order to reduce the need for blood transfusion after surgery.

Abstract
Background After total knee replacement, overall blood loss is often underestimated, although it exceeds the visible blood loss caused by bleeding into the tissues or into the joint. The use of fibrin sealants during surgery has been suggested to reduce perioperative blood loss and transfusion rates and may be beneficial for patient recovery and the postoperative function of the joint. Methods/Design This will be a single-centre, single-blinded, randomised controlled trial with a parallel design, for which 68 patients undergoing total knee replacement will be recruited and followed up at 3, 6 and 12 months; 34 will be control patients who will receive the standard orthopaedic surgery treatment (electrocoagulation), and the other 34 will receive the same treatment plus 5 ml EVICEL™ applied during surgery and used according to the manufacturer’s instructions. The primary objective is to test the null hypothesis that the effect of EVICEL™ for controlling haemostasis and reducing postoperative blood loss in patients undergoing total knee replacement is not superior to the use of electrocoagulation alone. The secondary objective is to show that EVICEL™ reduces the need for transfusion, increases range of motion, improves clinical outcome and wound healing, and reduces the need for analgesics. The tertiary objective is to show that EVICEL™ reduces the costs of total knee replacement treatment. Discussion So far, studies on the effect of fibrin sealants in total knee replacement have delivered inconsistent and ambivalent results, indicating that there is still a need for high-evidence studies as proposed in the presented study protocol. Trial registration German registration number DRKS00007564; date of registration: 26 November 2014.

Abstract
PURPOSE Fibrin sealant (FS) comprises a mixture of fibrinogen and thrombin that controls bleeding, reduces blood transfusions, improves tissue healing and shortens postoperative recovery time after various surgical procedures. However, no single study has been large enough to definitively determine whether fibrin sealant is safe and effective. We report a meta-analysis of randomized controlled trials (RCTs) evaluating the efficacy and safety of fibrin sealant in total knee arthroplasty. METHODS Articles published before August, 2012 were identified from PubMed, Embase, The Cochrane Library and other internet databases. Relevant journals and the recommendations of expert panels were also searched manually. We included only high-quality RCTs. Two independent reviewers searched and assessed the literature. Relevant data were analysed using RevMan 5.0. RESULTS Seven RCTs met the inclusion criteria. Use of fibrin sealant significantly reduced haemoglobin decline mean difference (MD = -0.72), 95 % confidence interval [95 % CI (-0.83, -0.62), p < 0.00001], postoperative drainage volume [MD = -354.53, 95 % CI (-482.43, -226.63), p < 0.00001], the proportion of patients requiring blood transfusion risk differences [RD = -0.27, 95 % CI (-0.45, -0.08), p = 0.006] and the incidence of wound haematoma [RD = -0.11, 95 % CI (-0.22, -0.00), p = 0.04]. There were no significant differences in deep vein thrombosis, pulmonary embolism, infection rate or other complications between groups. CONCLUSIONS Use of fibrin sealant in total knee arthroplasty was effective and safe, reduced haemoglobin decline, postoperative drainage volume, incidence of haematoma and need for blood transfusion, and did not increase the risk of complications. Due to the limited quality of the evidence currently available, more high-quality RCTs are required. LEVEL OF EVIDENCE II.

Abstract
BACKGROUND Fibrin sealant is frequently used in knee surgery as an adjuvant method for reducing postoperative bleeding, however, there is no consensus regarding the efficacy of fibrin sealant. HYPOTHESIS Fibrin sealant achieves better efficacy in terms of blood loss control, transfusion rate and units in knee surgery compared with controls. METHODS A search of the Cochrane Collaboration (2013 Issue 09), Embase (1974-2013.09), PubMed (1966-2013.09) and Chinese databases (up to 2013.09) were conducted. The Cochrane Collaboration's tool was used to assess for bias and data were analyzed by RevMan 5.29 software. RESULTS This study included nine RCTs and four prospective comparative trials with a total of 1299 patients. Compared to the control, fibrin sealant achieved a decrease in hemoglobin reduction [MD=1.14, 95% CI (0.61-1.67)], transfusion rate [OR=0.36, 95% CI (0.25-0.51)], transfusion units [MD=0.47, 95% CI (0.24-0.71)], hospital stay [MD=2.22, 95% CI (0.56-3.88)] and the incidence of complications [OR=0.56, 95% CI (0.38-0.83)]. And it also reduced total blood loss, while there was no significant difference [MD=155.83, 95% CI (-525.02-213.15)]. CONCLUSION Patients undergoing knee surgery would benefit from high-dose fibrin sealant with reduced transfusion rate and unit, hospital stay and complications, while they might benefit little from it in total blood loss. However, the effects of a low-dose of fibrin in knee surgery remain inconclusive.

Abstract
This study was designed to assess the use of platelet-rich plasma (PRP) during primary total knee arthroplasty (TKA). The authors hypothesized that this would result in less blood loss and greater hemoglobin and hematocrit levels at discharge and would potentially decrease the length of hospital stay. Leukocyte rich PRP was used during the procedure and at wound closure. Two surgeons performed all procedures in a similar fashion. Two different TKA implants were used. Each surgeon used the same implant throughout the study. A limited medial parapatellar approach was used and drains were used at closure. No tranexamic acid preparations were used. Continuous passive motion machines were used in all patients during their hospital stay. A total of 102 consecutive TKAs were performed. The study group (n=46) consecutively received the PRP injections during the TKA, whereas the control group (n=47) did not. Hemoglobin and hematocrit levels were obtained pre- and postoperatively. Estimated blood loss was recorded during surgery, and the auto-collection reinfusion drain system output was measured. The length of hospital stay was collected and recorded. The study showed that hemoglobin and hematocrit levels were not different when comparing study and control groups. Age and sex differences were insignificant. Finally, no statistical difference was seen for the estimated blood loss and hospital stay between the 2 groups. Platelet-rich plasma use during TKA does not decrease hospital stay or reduce estimated blood loss in the perioperative period.

Abstract
BACKGROUND This systematic review aimed to present and critically appraise the available information on the efficacy of platelet rich plasma (PRP) in equine and human orthopedic therapeutics and to verify the influence of study design and methodology on the assumption of PRP's efficacy. We searched Medline, PubMed, Embase, Bireme and Google Scholar without restrictions until July 2013. Randomized trials, human cohort clinical studies or case series with a control group on the use of PRP in tendons, ligaments or articular lesions were included. Equine clinical studies on the same topics were included independently of their design. Experimental studies relevant to the clarification of PRP's effects and mechanisms of action in tissues of interest, conducted in any animal species, were selected. RESULTS This review included 123 studies. PRP's beneficial effects were observed in 46.7% of the clinical studies, while the absence of positive effects was observed in 43.3%. Among experimental studies, 73% yielded positive results, and 7.9% yielded negative results. The most frequent flaws in the clinical trials' designs were the lack of a true placebo group, poor product characterization, insufficient blinding, small sampling, short follow-up periods, and adoption of poor outcome measures. The methods employed for PRP preparation and administration and the selected outcome measures varied greatly. Poor study design was a common feature of equine clinical trials. From studies in which PRP had beneficial effects, 67.8% had an overall high risk of bias. From the studies in which PRP failed to exhibit beneficial effects, 67.8% had an overall low risk of bias. CONCLUSIONS Most experimental studies revealed positive effects of PRP. Although the majority of equine clinical studies yielded positive results, the human clinical trials' results failed to corroborate these findings. In both species, beneficial results were more frequently observed in studies with a high risk of bias. The use of PRP in musculoskeletal lesions, although safe and promising, has still not shown strong evidence in clinical scenarios.

Abstract
BACKGROUND Platelet rich plasma (PRP) is a blood derivative concentrate of platelets, fibrin and growth factors obtained through withdrawal and centrifugation of autologous blood and use for its inherent hemostatic and adhesive properties to promote wound healing. Hip arthroplasty is often associated with significant perioperative complications including blood loss necessitating blood transfusions, which can lead to multiple adverse reactions, infection transmission, and longer hospital stay. MATERIALS AND METHODS We conducted this retrospective comparative study to determine whether the use of PRP can reduce the bleeding complications in hip replacement surgeries and therefore decrease analgesic requirements and shorten the hospital stay. RESULTS Sixty patients had consecutive hip replacement surgeries. The study group (n=23) received PRP applications while the control group (n=37) were operated without PRP applications. Postoperative drop of hemoglobin, number of red blood cell (RBC) transfusions, analgesic requirements, and duration of hospital stay were recorded. There was no significant difference in the drop of hemoglobin preoperatively and postoperatively comparing study and control groups (P=0.75). There was no difference in transfusion requirements between the two groups (P=0.16) but there was trend toward less transfusion in the PRP-treated group. There were also no statistical differences in analgesic use (P=0.83) and lengths of hospitalization (P=0.68) between the two groups. CONCLUSION We concluded that there is no clinical efficacy in using PRP in hip replacement surgeries. We recommend a larger prospective study be conducted to determine its clinical utility as an optimization strategy to improve outcome after hip arthroplasty.

Abstract
OBJECTIVES Blood loss reduction in total knee arthroplasty (TKA) contributes to the prevention of morbidity and mortality and in the management of health care costs. Fibrin haemostatic sealant have controversial effectiveness in reducing postoperative blood loss and transfusion requirements. Our study evaluated the medical and economic benefits of this treatment with the assumption that it decreases the frequency of blood transfusion after TKA. METHODS AND PATIENTS Our single-center and randomized study included 60 patients pose unilateral primary TKA for osteoarthritis. Distribution was done in 2 groups of 30 patients each. Group 1 patients treated with a dose of 5 mL Evicel®, compared to untreated group 2. Were collected the number of patients transfused. The treatment cost was compared to the sealant cost. RESULTS Results are not statistically significant. Two patients were transfused in group 1 and 3 in group 2 (P=0.64). The treatment cost for 30 patients is 13,500 €, for a savings of cells packed at 187 €, an additional cost of 13,313 € in group 1. CONCLUSION The use of fibrin haemostatic sealant in TKA did not induce a significant difference in terms of blood or transfusion savings, with a significant cost. We do not recommend its routine use in TKA.

Abstract
INTRODUCTION Blood transfusion is often required in total knee replacement (TKR); several methods of blood preservation are commonly used but the ideal solution is to reduce the blood loss during and after surgery. Aim of the study was to evaluate the hemostatic efficacy and safety of intravenous use of tranexamic acid in patients receiving TKR (cemented). MATERIALS AND METHODS Forty-five patients after TKR receive treatment with tranexamic acid (TXA, treatment group), and 45 were managed with fibrin tissue adhesive (control group). Hemoglobin values decrease and transfusions in both groups were recorded. Statistical analysis was performed with Student t test and χ (2) test. A statistical model was elaborated to evaluate together all variables and to underline what data can increase transfusions need. RESULTS A significant reduction was detected in hemoglobin values in the first 3 days after surgery in the treatment group. The difference in all cases was significant. When tranexamic acid was administered, the need for transfusions was lower (difference statistically significant). No major adverse events were recorded in our series. The use of autologous blood preparation before surgery led to a higher transfusion rate. CONCLUSION Tranexamic acid reduced blood loss in TKR and significantly reduced the blood transfusion need also when compared to fibrin tissue adhesive. The use of tranexamic acid is safe and in future may avoid preparation of autologous blood unit before surgery with a decrease of cost and medical figures involved.

Abstract
INTRODUCTION Reducing allogeneic blood transfusions remains a challenge in total knee arthroplasty. Patients with preoperative anemia have a particularly high risk for perioperative blood transfusions. MATERIALS AND METHODS 176 anemic patients (Hb < 13.5 g/dl) undergoing total knee replacement were prospectively evaluated to compare the effect of a perioperative cell saver (26 patients), intraoperative fibrin sealants (5 ml Evicel, Johnson & Johnson Wound Management, Ethicon, Somerville, NJ) (45 patients), preoperative autologous blood donation (PABD) (21 patients), the combination of fibrin sealants and preoperative autologous blood donation (44) and no intervention (40 patients) on perioperative blood loss and transfusion requirements. RESULTS All protocols resulted in significant reduction of allogeneic blood transfusions. Transfusion rates were similar with the use of PABD (19%), Evicel (18%), and cell saver (19%), all significantly lower than the control group (38 %, p < 0.05). Combining Evicel with PABD resulted in significantly higher wastage of autologous units (p < 0.05) with no significant reduction in allogeneic transfusion rate (14%). The use of fibrin sealant resulted in a significant reduction of blood loss compared to the PABD group (603 vs. 810 ml, p < 0.005) as well as the control group (603 vs. 822 ml, p < 0.005). CONCLUSIONS While PABD proved to be the most cost-effective treatment option in anemic patients, fibrin sealants and cell saver show similar reduction in allogeneic transfusion rates compared to controls. The combination of fibrin sealants and PABD is not cost-effective and increases the number of wasted units.

Abstract
OBJECTIVE A systematic review of randomized controlled trials was conducted to examine the efficacy of fibrin sealants for the reduction of postoperative blood loss and allogeneic red blood cell transfusion in total knee arthroplasty (TKA). METHODS Studies published through May 2013 were identified from PubMed, Embase, the Cochrane library, ScienceDirect, and other databases. Two independent reviewers assessed the quality of methodology using the Grade of Recommendations Assessment, Development and Evaluation approach and extracted data from literature. The mean difference (MD) of blood loss, hemoglobin loss, and risk ratios (RR) of transfusion rate and adverse events in the fibrin-treated and placebo groups were pooled throughout the study. The relevant data were analyzed using Stata 11.0 software. RESULTS Eight studies were included in the review, with a total sample size of 558 patients. The drainage blood loss [MD = -354.02 mL, 95% confidence interval (CI) (-500.87 to -207.18); P < 0.05], reduction in calculated total blood loss [MD = -402.12, 95% CI (-599.16 to -205.08); P < 0.05], hemoglobin loss [MD = -0.86 g/dL, 95% CI (-1.10 g/dL to -0.61 g/dL); P < 0.05], and transfusion rate [RR = 0.62, 95% CI (0.45-0.86); P < 0.05] were all significantly reduced following treatment with fibrin sealants. There were no significant differences in the incidence of adverse events [RR = 0.69, 95% CI (0.32-1.59); P > 0.05] among the study groups. CONCLUSIONS The results of the present meta-analysis suggest that fibrin sealants for patients undergoing TKA may reduce blood loss and maintain higher hemoglobin levels, particularly when fibrin sealants are used at higher dosage. Furthermore, fibrin sealants do not increase the risk of postoperative deep vein thrombosis, superficial infection, pulmonary embolism, and hematoma. Further evaluation is required to confirm our findings before fibrin sealants can be used in patients undergoing TKA. LEVEL OF EVIDENCE II.

Abstract
BACKGROUND Platelet rich plasma has been promoted as a biologic agent to enhance tissue healing. As a concentration of autologous growth factors, it has gained increased use in musculoskeletal applications. METHODS The purpose of this study was to evaluate the effect of intra-operative PRP on patient-reported outcomes 2 years after ACL reconstruction with tibialis anterior allograft. Fifty patients who underwent allograft ACL reconstruction with intra-operative application of PRP to the graft were matched with 50 allograft ACL -reconstructions without PRP use. The same surgeon performed all procedures with identical technique. Two year patient-reported outcomes including KOOS, IKDC, and Marx activity scores were obtained. Effusions in the immediate post-operative period, post-operative complications, and any subsequent procedures were also recorded. RESULTS There was no difference between the groups with respect to additional surgeries or complications in the first 2 years after reconstruction. Decreased effusions at 10±4 days were noted in the PRP group, but this difference disappeared by 8±4 weeks. No differences in patient-reported outcomes were noted in the 58 patients with two-year outcome data. CONCLUSION The study demonstrated that although PRP application in tibialis allograft ACL reconstructions appeared safe; clinical benefit was minor and short-term. No differences in patient-reported outcomes or number of additional surgeries at 2 years were noted. LEVEL OF EVIDENCE Level III - retrospective comparative study.

Abstract
Autologous platelet rich plasma preparations, commonly referred to as platelet gel, have been reported to have benefits when used in total knee replacement of less blood loss and better motion, with few reported complications. This retrospective review of 268 consecutive primary total knee arthroplasty cases compares postsurgical range of motion at 2, 8, and 12 weeks, knee manipulation rates, change in hemoglobin, and complications between one group receiving a platelet gel preparation (135 cases), and an equivalent group receiving no platelet gel preparation (133 control cases). No difference was found between groups in manipulation rates, knee range of motion, or changes in hemoglobin (P > 0.05). The use of platelet gel in this study did not have a significant effect on hemoglobin at 72 hours postoperatively, knee range of motion, or manipulation rates up to 3 months post-op in this patient cohort.

Abstract
BACKGROUND AND PURPOSE Blood loss after total knee arthroplasty (TKA) may lead to anemia, blood transfusions, and increased total costs. Also, bleeding into the periarticular tissue may cause swelling and a reduction in quadriceps strength, thus impairing early functional recovery. In this randomized, double-blind, placebo-controlled study, we analyzed the possible effect of fibrin sealant on blood loss and early functional recovery in a fast-track setting. METHODS 24 consecutive patients undergoing bilateral simultaneous TKA were included. 10 mL of fibrin sealant (Evicel) was sprayed onto one knee whereas the contralateral knee had saline. Drain output, the primary outcome, was measured from knee drains removed exactly 24 h after surgery. Secondary outcomes (knee swelling, pain, strength of knee extension, and range of movement (ROM)) were evaluated up to 21 days after surgery. RESULTS The drain output in knees treated with fibrin sealant and placebo was similar (582 mL and 576 mL, respectively). Likewise, no statistically significant differences were found between groups regarding swelling, pain, strength of knee extension, and ROM. INTERPRETATION Fibrin sealant as a local hemostatic in TKA showed no benefit in reducing drain output or in facilitating early functional recovery when used with a tourniquet, tranexamic acid, and a femoral bone plug.

Abstract
Objective: To develop and test a decision-support tool for prioritizing new competing Health Technologies (HTs) after their assessment using the mini-HTA approach.Methods:A two layer value/risk tool was developed based on the mini-HTA. The first layer included 12 mini-HTA variables classified in two dimensions, namely value (safety, clinical benefit, patient impact, cost-effectiveness, quality of the evidence, innovativeness) and risk (staff, space and process of care impacts, incremental costs, net cost, investment effort). Weights given to these variables were obtained from a survey among decision-makers (at National/Regional level and hospital settings). A second layer included results from mini-HTA (scored as higher, equal or lower), which compares the performance of the new HT (in terms of the abovementioned 12 variables) with the available comparator. An algorithm combining the first (weights) and second (scores) layers was developed to obtain an overall score for each HT, which was then plotted in a value/risk matrix. The tool was tested using results from the mini-HTAs for three new HTs (Surgical Robot, Platelet Rich Plasma, Deep Brain Stimulation).Results: No significant differences among decision-makers were observed as regards the weights given to the 12 variables, therefore, the median aggregate weights from decision-makers were introduced in the first layer. The dot plot resulting from the mini-HTA presented good power to visually discriminate between the assessed HTs.Conclusion: The decision-support tool developed here makes possible a robust and straightforward comparison of different competing HTs. This facilitates hospital decision-makers deliberations on the prioritization of competing investments under fixed budgets.

Abstract
Fast-track hip and knee arthroplasty aims at giving the patients the best available treatment at all times, being a dynamic entity. Fast-track combines evidence-based, clinical features with organizational optimization including a revision of traditions resulting in a streamlined pathway from admission till discharge – and beyond. The goal is to reduce morbidity, mortality and functional convalescence with an earlier achievement of functional milestones including functional discharge criteria with subsequent reduced length of stay and high patient satisfaction. Outcomes are traditionally measured as length of stay; safety aspects in the form of morbidity/mortality; patient satisfaction; and – as a secondary parameter – economic savings. Optimization of the clinical aspects include focusing on analgesia; DVT-prophylaxis; mobilization; care principles including functional discharge criteria; patient-characteristics to predict outcome; and traditions which may be barriers in optimizing outcomes. Patients should be informed and motivated to be active participants and their expectations should be modulated in order to improve satisfaction. Also, organizational aspects need to be analyzed and optimized. New logistical approaches should be implemented; the ward ideally (re)structured to only admit arthroplasties; the staff educated to have a uniform approach; extensive preoperative information given including discharge criteria and intended length of stay. This thesis includes 9 papers on clinical and organizational aspects of fast-track hip and knee arthroplasty (I–IX). A detailed description of the fast-track set-up and its components is provided. Major results include identification of patient characteristics to predict length of stay and satisfaction with different aspects of the hospital stay (I); how to optimize analgesia by using a compression bandage in total knee arthroplasty (II); the clinical and organizational set-up facilitating or acting as barriers for early discharge (III); safety aspects following fast-track in the form of few readmissions in general (IV) and few thromboembolic complications in particular (V); feasibility studies showing excellent outcomes following fast-track bilateral simultaneous total knee arthroplasty (VI) and non-septic revision knee arthroplasty (VII); how acute pain relief in total hip arthroplasty is not enhanced by the use of local infiltration analgesia when multi-modal opioid-sparing analgesia is given (VIII); and a detailed description of which clinical and organizational factors detain patients in hospital following fast-track hip and knee arthroplasty (IX). Economic savings following fast-track hip and knee arthroplasty is also documented in studies, reviews, metaanalyses and Cochrane reviews – including the present fast-track (ANORAK). In conclusion, the published results (I–IX) provide substantial, important new knowledge on clinical and organizational aspects of fast-track hip and knee arthroplasty – with concomitant documented high degrees of safety (morbidity/mortality) and patient satisfaction. Future research strategies are multiple and include both research strategies as efforts to implement the fast-track methodology on a wider basis. Research areas include improvements in pain treatment, blood saving strategies, fluid plans, reduction of complications, avoidance of tourniquet and concomitant blood loss, improved early functional recovery and muscle strengthening. Also, improvements in information and motivation of the patients, preoperative identification of patients needing special attention and detailed economic studies of fast- track are warranted.

Abstract
A prospective, randomised controlled trial compared the effects of two medications intended to reduce blood loss from total knee arthroplasty. Patients were randomised to one of the following three treatment groups: 10mg/kg tranexamic acid at given at induction of anaesthesia, 10 ml of fibrin spray administered topically during surgery, or to a control group receiving neither treatment. Sixty six patients underwent elective cemented total knee arthroplasty; computer navigation was used in all cases. There was no significant difference in blood loss between the tranexamic acid and fibrin spray groups (p=0.181). There was no significant difference in blood loss between the tranexamic acid and fibrin spray groups(p=0.181). The fibrin spray led to a significant reduction in blood loss compared to control (p=0.007). The effect of tranexamic acid did not reach significance (p=0.173). We conclude that fibrin spray was effective in reducing blood loss but that with a study of this power, we were unable to detect an effect of tranexamic acid in cemented navigated total knee replacement at the dose used.

Abstract
BACKGROUND Total knee arthroplasty is associated with a significant postoperative blood loss even without any form of perioperative anticoagulation. METHODS The potential role of QUIXIL(®), a fibrin sealant used in orthopaedic surgery to control blood loss and avoid blood transfusions in patients undergoing total knee arthroplasty was evaluated in a prospective randomized trial with twenty-four patients diagnosed with primary osteoarthritis of the knee. RESULTS Results showed that application of 2 ml QUIXIL(®) adds costs to treatment without reducing the number of transfused red blood cell counts and postoperative haemoglobin loss. However, significant lower levels of postoperative fluid loss (P = 0.026) was detected in QUIXIL(®) treated patients. CONCLUSION Regarding cost effectiveness and benefit no indication for the use of 2 ml QUIXIL(®) fibrin sealant in standard knee arthroplasty could be proofed statistically.

Abstract
Bleeding after total knee arthroplasty increases the risk of pain, delayed rehabilitation, blood transfusion, and transfusion-associated complications. The authors compared pre- and postoperative decreases in hemoglobin as a surrogate for blood loss in consecutive patients treated at a single institution by the same surgeon (J.L.C.) using conventional hemostatic methods (electrocautery, suturing, or manual compression) or a gelatin and thrombin-based hemostatic matrix during total knee arthroplasty. Data were collected retrospectively by chart review. The population comprised 165 controls and 184 patients treated with hemostatic matrix. Median age was 66 years (range, 28-89 years); 66% were women. The arithmetic mean ± SD for the maximal postoperative decrease in hemoglobin was 3.18 ± 0.94 g/dL for controls and 2.19 ± 0.83 g/dL for the hemostatic matrix group. Least squares means estimates of the group difference (controls-hemostatic matrix) in the maximal decrease in hemoglobin was 0.96 g/dL (95% confidence interval, 0.77-1.14 mg/dL; P<.0001). Statistically significant covariate effects were observed for preoperative hemoglobin level (P<.0001) and body mass index (P=.0029). Transfusions were infrequent in both groups. The frequency of acceptable range of motion was high (control, 88%; hemostatic matrix, 84%). In both groups, overall mean tourniquet time was approximately 1 hour, and the most common length of stay was 3 to 5 days. No serious complications related to the hemostatic agent were observed. These data demonstrate that the use of a flowable hemostatic matrix results in less reduction in hemoglobin than the use of conventional hemostatic methods in patient undergoing total knee arthroplasty.

Abstract
Background Blood transfusion is often required in total knee replacement; various methods of blood preservation have been studied. The best solution is to reduce the loss of blood during and after surgery. Materials and methods We designed this study to evaluate the hemostatic efficacy and safety of fibrin tissue adhesive (Quixil) in patients receiving total knee arthroplasty [low contact stress (LCS, DePuy, Warsaw, IN, US) cementless total knee replacement (TKR)] with a prospective, randomized, standard treatment controlled study. Thirty-five patients were randomized to receive treatment with fibrin tissue adhesive (treatment group), and 35 were randomized to be managed with postoperative blood recovery and reinfusion (control group). Blood loss in suction drain, decrease in hemoglobin values, and transfusions were recorded. Results A significant reduction in apparent total blood loss was detected in the treatment group compared with the control group. There was also a lower decrease in hemoglobin level, although this difference was not significant. When fibrin tissue adhesive was administered, the need for transfusions was lower. No major adverse events were recorded in our series. Conclusions Fibrin tissue adhesive reduced blood loss in TKR and seemed to significantly reduce the need for blood transfusion. Fibrin tissue adhesive can be an appropriate solution to enhance hemostasis and vessel sealing at the operative site in TKR, in order to reduce blood loss after surgery and the risk of complications.

Abstract
BACKGROUND The recent emergence of autologous blood concentrates, such as platelet-rich plasma, as a treatment option for patients with orthopaedic injuries has led to an extensive debate about their clinical benefit. We conducted a systematic review and meta-analysis to determine the efficacy of autologous blood concentrates in decreasing pain and improving healing and function in patients with orthopaedic bone and soft-tissue injuries. METHODS We searched MEDLINE and Embase for randomized controlled trials or prospective cohort studies that compared autologous blood concentrates with a control therapy in patients with an orthopaedic injury. We identified additional studies by searching through the bibliographies of eligible studies as well as the archives of orthopaedic conferences and meetings. RESULTS Twenty-three randomized trials and ten prospective cohort studies were identified. There was a lack of consistency in outcome measures across all studies. In six randomized controlled trials (n = 358) and three prospective cohort studies (n = 88), the authors reported visual analog scale (VAS) scores when comparing platelet-rich plasma with a control therapy across injuries to the acromion, rotator cuff, lateral humeral epicondyle, anterior cruciate ligament, patella, tibia, and spine. The use of platelet-rich plasma provided no significant benefit up to (and including) twenty-four months across the randomized trials (standardized mean difference, -0.34; 95% confidence interval [CI], -0.75 to 0.06) or the prospective cohort studies (standardized mean difference, -0.20; 95% CI, -0.64 to 0.23). Both point estimates suggested a small trend favoring platelet-rich plasma, but the associated wide confidence intervals were consistent with nonsignificant effects. CONCLUSIONS The current literature is complicated by a lack of standardization of study protocols, platelet-separation techniques, and outcome measures. As a result, there is uncertainty about the evidence to support the increasing clinical use of platelet-rich plasma and autologous blood concentrates as a treatment modality for orthopaedic bone and soft-tissue injuries.

Abstract
Platelet-rich plasma (PRP) is increasingly used in the management of tendon injury in sports, supposedly accelerating the process of healing, tissue regeneration, and return to play. However, the scientific clinical evidence to support its use is scanty, and more level I studies need to be performed to justify its widespread use.

Abstract
BACKGROUND Platelet-rich plasma (PRP) has been shown to be a general stimulation for repair and 1-year results showed promising success percentages. PURPOSE This trial was undertaken to determine the effectiveness of PRP compared with corticosteroid injections in patients with chronic lateral epicondylitis with a 2-year follow-up. STUDY DESIGN Randomized controlled trial; Level of evidence, 1. METHODS The trial was conducted in 2 Dutch teaching hospitals. One hundred patients with chronic lateral epicondylitis were randomly assigned to a leukocyte-enriched PRP group (n = 51) or the corticosteroid group (n = 49). Randomization and allocation to the trial group were carried out by a central computer system. Patients received either a corticosteroid injection or an autologous platelet concentrate injection through a peppering needling technique. The primary analysis included visual analog scale (VAS) pain scores and Disabilities of the Arm, Shoulder and Hand (DASH) outcome scores. RESULTS The PRP group was more often successfully treated than the corticosteroid group (P < .0001). Success was defined as a reduction of 25% on VAS or DASH scores without a reintervention after 2 years. When baseline VAS and DASH scores were compared with the scores at 2-year follow-up, both groups significantly improved across time (intention-to-treat principle). However, the DASH scores of the corticosteroid group returned to baseline levels, while those of the PRP group significantly improved (as-treated principle). There were no complications related to the use of PRP. CONCLUSION Treatment of patients with chronic lateral epicondylitis with PRP reduces pain and increases function significantly, exceeding the effect of corticosteroid injection even after a follow-up of 2 years. Future decisions for application of PRP for lateral epicondylitis should be confirmed by further follow-up from this trial and should take into account possible costs and harms as well as benefits.

Abstract
PURPOSE Total knee arthroplasty (TKA) is often associated with major postoperative blood loss, postoperative pain, and impaired wound healing. The application of autologous platelet gel (APG), prepared from the buffy coat of a unit of autologous blood, has been advocated to improve haemostasis after surgery, to decrease perioperative blood loss, diminish postoperative pain and to enhance the wound healing process. This randomized controlled pilot study was developed to assess the effects of APG after total knee arthroplasty on blood loss, wound healing, pain, range of motion, and hospital stay. METHOD A prospective, randomized observer blind controlled trial was performed. Forty patients with only osteoarthritis of the knee were scheduled to have a TKA, and they were randomized into two groups. Patients in the treatment group were all treated with the application of autologous platelet gel after the prosthesis was implanted. Patients in the control group were treated with the same protocol but no APG was used. RESULTS Preoperative and postoperative Hb levels showed no significant difference and allogenic blood transfusions were not given in either group. Haematomas were significantly larger in the control group than in the platelet gel group (P = 0.03). The pain score at rest was higher in the control group on the 3rd day (P = 0.04). Wound healing disturbances were seen in four patients in the control group and in no patients in the APG group (n.s.). Range of motion of the knee was similar postoperatively. Hospital stay was 6.2 days in the APG and 7.5 days in the control group (n.s.). CONCLUSION In this prospective randomized pilot study on APG in total knee arthroplasty, differences in favour of the use of platelet gel were found, but these were subjective evaluations, marginal in effect, or did not reach statistical significance. The use of drains might have decreased the concentration of delivered platelets and may have diminished the effect. However, in this study, a statistically significant clinically important effect in favour of platelet gel application was not found. Further studies with larger numbers of patients, and without the use of drains, are warranted to investigate the possible benefits of autologous platelet gel in total knee arthroplasty.

Abstract
Drainage-clamping methods are thought to be effective in reducing blood loss after total knee arthroplasty (TKA). We conducted a systematic review to examine if these methods were effective without increasing the risk of complications. After a comprehensive search, 6 randomized controlled trials involving 603 knees and comparing clamping drainage and the immediate release of the drain after elective TKA were included in this analysis. The results demonstrated that drainage clamping could decrease the volume of drainage, but only clamping for no less than 4 hours could reduce the true blood loss. There was no significant difference between the 2 groups regarding blood transfusion, postoperative range of motion, incidence of thromboembolic events, and wound complications. The current evidence cannot confirm the advantage of clamping drainage after TKA.

Abstract
Arthroscopic acromioplasty, one of the most frequent procedures in shoulder surgery, can promote tissue healing process by the release of growth/angiogenic factors from the acromion. Matrix metalloproteinases MMP-2 and MMP-9 are involved in such process. The purpose of this study was to measure MMP-2 and MMP-9 levels in the articular fluid and in the peripheral blood of patients undergoing arthroscopic acromioplasty in order to better understand the local involvement of such factors in the healing process after surgical procedures. Concentrations of MMP-2 and MMP-9 in the subacromial space and peripheral blood collected shortly after surgery were determined by ELISA. MMP-2 and MMP-9 concentrations were measured in the subacromial fluid of 23 patients. In subacromial fluid, the levels between MMP-2 and MMP-9 did not reach statistical significance (127.15±45.56 vs 149.41±53.61 pg/ml, respectively, p>0.05). Peripheral blood levels of MMP-2 (130.75±47.48 pg/ml) were comparable to the subacromial fluid ones (127.15±45.56 pg/ml) whereas MMP-9 level was higher in the subacromial space (149.41±53.61 pg/ml) than in the peripheral blood (67.61±12.62 pg/ml, p<0.001). This work suggests that the measurement of bone specific MMPs (MMP-2 and MMP-9) can be an useful tool to be monitored in parallel with growth factor levels and other bone turnover markers in order to evaluate the bone remodelling and tissue healing processes. This study suggests that the measurement of bone specific MMPs levels, in particular MMP-9, may evaluate the bone remodelling and healing after arthroscopic shoulder acromioplasty.

Abstract
Fibrin glue, also known as fibrin sealant, is now established as a haemostatic agent in surgery, but its role in orthopaedic surgery is neither well known nor clearly defined. Although it was originally used over 100 years ago, concerns about transmission of disease meant that it fell from favour. It is also available as a slow-release drug delivery system and as a substrate for cellular growth and tissue engineering. Consequently, it has the potential to be used in a number of ways in orthopaedic surgery. The purpose of this review is to address its use in surgery of the knee in which it appears to offer great promise.

Abstract
The role of wound drainage in total knee arthroplasty (TKA) is controversial. The use of drainage was believed to be effective in decreasing hematoma formation, but it inevitably increases bleeding because the tamponade effect of a closed and undrained wound is eliminated. Clamping the drain tube in the first 4 hours after TKA can temporarily recreate a tamponade effect for bleeding control. Previous studies compared the clamping drainage with the conventional drainage method but not with non-drainage. Some current studies have shown that drainage in TKA is not necessary. Thus, we conducted a study to compare the outcomes between the patients with temporarily clamping drainage and without drainage.One hundred consecutive patients undergoing primary TKA were included. Change of hemoglobin, blood transfusion, use of narcotics, postoperative wound dressing, length of hospital stay, and range of motion were recorded. The drain-clamping group demonstrated more postoperative hemoglobin loss and a longer hospital stay, and gained no benefit compared with the non-drain group. Therefore, we concluded that despite clamping for 4 hours after TKA, the drain was still of no use. We would not recommend using a draining system routinely after TKA.

Abstract
Blood conservation, specifically the avoidance of allogeneic blood transfusion, is becoming an important aspect of preoperative planning and intraoperative decision making in orthopaedic surgery. Knee and hip arthroplasty, as well as certain spine procedures, place patients at risk of significant blood loss. Fibrin sealants are topically applied hemostatic agents that reduce the time required to achieve hemostasis as well as the volume of blood loss. Fibrin sealants may provide additional benefits beyond hemostasis, such as improvements in wound healing and postoperative range of motion as well as lower rates of wound infections.

Abstract
It has recently been postulated that a variety of growth factors may be released from cancellous bone after an acromioplasty. The aim of this study was to demonstrate the presence of growth factors in the subacromial space after acromioplasty. Between October 2006 and March 2007, 23 patients underwent arthroscopic acromioplasty. A sample of at least 3 ml of fluid from the shoulder was obtained 15 min after the end of the procedure. At the same time another sample of 3 ml of the patient's venous blood was obtained as a control. The concentrations of growth factors in the fluids collected were determined using enzyme-linked immunosorbent assay (ELISA). The growth factors assayed were platelet-derived growth factor-AB (PDGF-AB), basic fibroblast growth factor basic (bFGF) and transforming growth factor beta 1 (TGF-beta1). The concentrations of TGF-beta1 (p = 0.0001), PDGF-AB (p = 0.02), and bFGF (p < 0.0001) were significantly higher in the fluid from the subacromial space than in the blood sample. There are high concentrations of several growth factors in the subacromial space after acromioplasty.

Abstract
Objective: The present study was performed in order to evaluate the use of platelet rich plasma associated to bone marrow aspirate, substituting autologous iliac bone graft in medial opening wedge osteotomy (OWHTO). Methods: Twenty-five patients were submitted to tibial opening wedge osteotomy, being divided into two groups. Iliac group: 14 patients submitted to OWHTO, using autologous iliac bone graft to fill the gap. PRP group: 11 patients using platelet rich plasma associated to bone marrow aspirate to fill the gap. We evaluated bleeding (hemoglobin and hematocrit levels) and pain (visual analogic scale-VAS), then we compared the groups regarding these variables. Results: Differences between the groups were not found regarding hemoglobin levels (p=0.820) and hematocrit levels (p=0.323). The groups were not different regarding pain measured with VAS (p=0.538). Conclusion: The use of platelet rich plasma associated to bone marrow aspirate in medial opening wedge osteotomy did not offer advantages over autologous iliac bone graft regarding bleeding and pain.

Abstract
BACKGROUND The platelet gel is made by embedding concentrate platelets within a semisolid (gel) network of polymerized fibrin. It is believed that this blood component will be used more and more in the treatment of several clinical conditions and as an adjunctive material in tissue engineering. Several systems are available to produce platelet-rich plasma (PRP) for topical therapy. Recently, a new system became commercially available, Plateltex. Here we report the technical performance of this system in comparison with the performance of other commercially available systems: PRGF, PRP-Landesber, Curasan, PCCS, Harvest, Vivostat, Regen and Fibrinet. MATERIAL AND METHODS Both the PRP and the gel were prepared according to the manufacturer's directions. The blood samples of 20 donors were used. The yield, the efficiency, and the amount of platelet-derived growth factor AB (PDGF-AB), transforming growth factor beta, vascular endothelial growth factor and fibroblast growth factor were measured in the resulting PRP. The feature of the batroxobin-induced gelation was evaluated. RESULTS The yield, the collection efficiency and the growth factor content of Plateltex were comparable to those of most of the other available systems. The gelation time was not dependent on the fibrinogen concentration; however, it was strongly influenced by the contact surface area of the container where the clotting reaction took place (P < 0.0001). CONCLUSIONS Plateltex provided platelet recovery, collection efficiency and PDGF-AB availability close to those provided by other systems marketed with the same intended use. Batroxobin, the enzyme provided to induce gelation, acts differently from thrombin, which is used by most other systems. Platelets treated with thrombin become activated; they release their growth factors quickly. Furthermore, thrombin-platelet interaction is a physiological mechanism that hastens the clot-retraction rate. On the contrary, platelets treated with batroxobin do not become activated; they are passively entrapped within the fibrin network, and their growth factor release occurs slowly. In these conditions, the clot retraction takes longer to occur. According to these differences between thrombin and batroxobin, it is expected that batroxobin-induced PRP activation will tailor slow release of the platelet content, thus, providing longer in loco availability of trophic factors. In selected clinical conditions, this durable anabolic factor availability might be preferable to quick thrombin-induced growth factor release.

Abstract
BACKGROUND Platelet-leukocyte gel (PLG) is being used during various surgical procedures in an attempt to enhance the healing process. We studied the effects of PLG on postoperative recovery of patients undergoing open subacromial decompression (OSD). METHODS PLG was produced from platelet-leukocyte-rich plasma (P-LRP), prepared from a unit of whole blood. Forty patients were included in the study. Self-assessed evaluations, using the American Shoulder and Elbow Surgeons scoring system of activities of daily living (ADL), joint instability, pain levels, pain medications, and clinical evaluations for range of motion were conducted. RESULTS Platelet and leukocyte counts were significantly increased in the P-LRP compared to baseline counts. Treated patients demonstrated decreased visual analog scales for pain and used significantly less pain medication, had an improved range of motion during passive forward elevation, external rotation, external rotation with arm at 90 degrees abduction, internal rotation, and cross body adduction compared to control patients (p < 0.001). No differences in the instability score were observed between the groups. Furthermore, treated patients performed more ADL (p < 0.05). CONCLUSION In the PLG-treated group, recovery was faster and patients returned earlier to daily activities and also took less pain medication than control subjects.
