INTRODUCTION: Quadriceps strength after arthroscopic knee procedures is frequently diminished several years postoperation. Blood flow restriction (BFR) training uses partial venous occlusion while performing submaximal exercise to induce muscle hypertrophy and strength improvements. The purpose of this study was to evaluate BFR as a postoperative therapeutic intervention after knee arthroscopy. METHODS: A randomized controlled pilot study comparing physical therapy with and without BFR after knee arthroscopy was conducted...

Pre-test probability scoring and blood tests for deep venous thrombosis (DVT) assessment are sensitive but not specific leading to increased demands on radiology services. 385 patients presenting to an Emergency Department with suspected DVT were studied to explore our actual work up of patients with possible DVT relating to risk stratification, further investigation and follow up. Of the 205 patients with an initially negative scan, 36 (17.6%) were brought for review to the Emergency Department Consultant clinic...

Varicose vein disease is characterized by tenacious tendency to recur. Measures recommended to prevent recurrences (flush ligation at the saphenofemoral junction, removal of incompetent great saphenous vein in the thigh, and insertion of mechanical barriers in the fossa ovalis) did not succeed in preventing recurrence. Reflux recurrence is triggered by the hemodynamic phenomenon called hemodynamic paradox. Abolition of saphenous reflux removes the hemodynamic disturbance of any degree of severity but at the same time it releases the pathological process leading to recurrent reflux...

Introduction Venous thromboembolism (VTE) is a potentially fatal complication of hip arthroplasty and knee arthroplasty. The National Institute for Health and Care Excellence recommend rivaroxaban for VTE prevention. Amid concerns over bleeding complications, the modified thromboprophylaxis policy of Chelsea and Westminster Hospital (CWH; London, UK) advises enoxaparin given after surgery in the inpatient setting followed by rivaroxaban upon hospital discharge. This retrospective study investigated the efficacy and safety of rivaroxaban in this novel, modified venous-prophylaxis regimen in a surgical orthopaedic cohort at CWH...

PURPOSE: To compare the use of topical tranexamic acid (TXA) with postoperative autologous transfusion (PAT) in terms of blood loss, need for allogeneic blood transfusion, and cost-effectiveness. METHODS: Records of 25 men and 125 women (mean age, 67 years) who underwent primary unilateral total knee arthroplasty (TKA) and were randomised to the PAT group (n=50), topical TXA group (n=50), or routine drainage group (control) [n=50] were reviewed. Pre- and post-operative haemoglobin level, total postoperative drainage volume, and the need for allogeneic blood transfusion were recorded...

BACKGROUND: Controversy continues regarding the use of powerful anticoagulants for venous thromboembolism prophylaxis in patients undergoing total knee arthroplasty (TKA). To comply with institution-mandated guidelines and pressure from hospitalist intent on complying with conventionally recommended anticoagulation guidelines, we singularly changed our chemoprophylaxis practice from using aspirin to Lovenox and noted that transfusion rates increased substantially. METHODS: A retrospective case review was performed to evaluate transfusion requirement differences in primary TKA patients receiving Lovenox (unilateral TKA: n = 135, bilateral TKA: n = 44) or aspirin (unilateral TKA: n = 153, bilateral TKA: n = 45) for venous thromboembolism prophylaxis...

BACKGROUND: The use of autologous superficial femoral veins (SFV) as an arterial or venous substitute represents a valuable technique in modern vascular surgery with versatile indications. The SFV autografts exhibit excellent control of infection and durable long-term results in terms of graft patency in prosthetic or arterial infections. In cases of elective use of the SFV, duplex ultrasound evaluation of the deep leg vein system should be implemented to confirm the patency of the profunda femoris vein...

BACKGROUND: Venous thromboembolism (VTE) including deep vein thrombosis (DVT) and pulmonary embolism (PE) frequently occurs in patients undergoing total knee arthroplasty (TKA). This study aimed to evaluate the efficacy of dielectric blood coagulometry (DBCM) as a new technique for predicting postoperative VTE. METHODS: Thirty patients undergoing TKA were enrolled. DVT was diagnosed by ultrasonography preoperatively and on the fourth or fifth postoperative day. Enhanced computed tomography (CT) was performed to detect PE on the fourth postoperative day...

BACKGROUND: The optimal technique to detect venous reflux requires a patient to be standing with weight on one leg while the other leg is scanned for superficial venous reflux (standing position [SP] technique). This represents a significant hardship for a subset of patients who are unable to stand and adequately maintain their balance. This study examines the predictability of identifying venous reflux using a reverse Trendelenburg 60° (RT-60) when compared with the SP in the great saphenous vein (GSV) and small saphenous vein (SSV)...

BACKGROUND: The purpose of this study was to compare the complications and mortality between bilateral simultaneous total knee arthroplasty (BTKA-Simultaneous) and bilateral staged TKA (BTK-Staged) while adjusting for differences in patient, surgeon, and hospital characteristics. METHODS: An integrated health care system total joint registry was used to compare patients undergoing BTKA-Simultaneous to BTKA-Staged. For outcomes related to revision and infection, the sample included 11,118 patients, and for outcomes of death, acute myocardial infarction, stroke, and venous thromboembolism, a subsample of 7991 patients with comorbidity data was selected...

BACKGROUND: Venous thromboembolism (VTE) is a known complication of total knee arthroplasty (TKA). In addition, obesity has been implicated as a risk factor and justification for chemoprophylaxis for VTE. We wanted to review the prevalence of VTE among our patients and evaluate the incidence rates of VTE among nonobese and obese patients. METHODS: We reviewed 894 patients who underwent elective unilateral total knee arthroplasty by a single surgeon from March 2003 to November 2014 in our center...

The purpose of this study was to compare and evaluate the event of VTE (Venous Thromboembolism Event) after total artificial joint replacement between two groups diagnosed with either musculoskeletal tumors or osteoarthritis (OA) of the knee. From 2004 to 2014, a total of 1,402 patients (308 in tumor group, 1,094 in OA group) were involved in this study. The rate of asymptomatic DVT (Deep vein thrombosis) was significantly higher in tumor group when compared with OA group. Though both the incidence of symptomatic DVT and PE (Pulmonary embolism) were slightly higher in tumor group, no significant difference was detected...

BACKGROUND: Guidelines from the Japanese Circulation Society recommend prophylaxis with anticoagulation plus intermittent pneumatic compression or graduated compression stockings (GCS) among patients at the highest risk for developing venous thromboembolism (VTE). However, the benefits of concomitant GCS use for patients undergoing total knee arthroplasty (TKA) and receiving anticoagulation remain unknown. In this study, the efficacy of GCS plus anticoagulation compared with anticoagulation alone was evaluated among patients undergoing TKA...

BACKGROUND: The optimal dosage and timing of tranexamic acid (TXA) in total knee arthroplasty (TKA) are undetermined. The purpose of this study was to explore the effect of multiple boluses of intravenous TXA on hidden blood loss (HBL), inflammatory response, and knee function after primary TKA without tourniquet. METHODS: A total of 151 patients were randomly divided into 3 groups to receive single bolus of 20 mg/kg IV-TXA before skin incision (group A), or another bolus of 10 mg/kg IV-TXA 3 hours later (group B), or another 2 boluses of 10 mg/kg IV-TXA 3 hours and 6 hours later (group C)...

OBJECTIVES: Venous aneurysms are uncommon. They can involve both superficial and deep venous systems. We hereby present a unique case of gastrocnemius venous aneurysm developed after compressive knee trauma. REPORT: A large venous aneurysm in the left popliteal fossa was detected by chance in a 44-year-old woman one month after a compressive trauma to the posterior surface of the knee. Magnetic resonance-imaging of the same knee had documented normal venous anatomy one year earlier...
