INTRODUCTION: Blood loss in Total Joint Arthroplasty can be significant and often under-estimated. This study aims to investigate the safety and efficacy of different routes of tranexamic acid (TXA) administration in reducing blood transfusion after Total Hip Arthroplasty (THA) and Total Knee Arthroplasty (TKA). The secondary aim is to find the safest and most efficacious route and dose of TXA. MATERIAL AND METHODS: PubMed, Embase, Cochrane library, China National Knowledge Infrastructure, and OpenGrey were systemically searched for randomised controlled trials investigating the efficacy and/or safety of TXA for THA and/or TKA...

Varus misalignment of the hip-knee-ankle angle causes greater loads on the medial compartment of the knee and increases the risk of developing knee osteoarthritis. High tibial osteotomy is a surgical method where the load-bearing axis is shifted laterally. The purpose of this study is to define a subject-specific three-dimensional multibody model of the knee to investigate the effect of osteotomy on cartilages and menisci during the stance phase of gait. It is assumed that osteotomy transfers load-bearing to the lateral parts of the knee...

During the fifth century BC in ancient Greece during the eve of orthopaedics, the Hippocratic School of Medicine diagnosed a series of congenital limb deformities. Congenital dislocation of the arm, elbow, wrist, hip, knee, tarsotibial joint, apex leg, as well as talipes valgus (clubfoot), congenital clavicle fractures, and thumb malfunction were all discussed by Hippocrates and his followers. Ancient Greek medico-philosophers, fond of a "perfect" human body, proposed an immediate non-interventional approach, while archaic orthotics and specialized footwear were suggested...

BACKGROUND: Whether prolonged operative time is an independent risk factor for subsequent surgical site infection (SSI) and periprosthetic joint infection (PJI) following total joint arthroplasty (TJA) remains a clinically significant and underexplored issue. The aim of this study is to investigate the association between operative time and the risk of subsequent SSI and PJI in patients undergoing primary TJA. METHODS: We retrospectively reviewed 17,342 primary unilateral total knee arthroplasty and total hip arthroplasty performed at a single institution between 2005 and 2016, with a minimum follow-up of 1 year...

BACKGROUND: Evolving reimbursement models increasingly compel hospitals to assume costs for 90-day readmission after total joint arthroplasty. Although risk assessment tools exist, none currently reach the predictive performance required to accurately identify high-risk patients and modulate perioperative care accordingly. Although unlikely to perform adequately alone, the Elixhauser index is a set of 31 variables that may lend value in a broader model predicting 90-day readmission. METHODS: Elixhauser comorbidities were examined in 10,022 primary unilateral total joint replacements, of which 4535 were hip replacements and 5487 were knee replacements, all performed between June 2013 and January 2018 at a single tertiary referral center...

PURPOSE: This study aimed to investigate the influence of whole-body vibration (WBV) frequency, amplitude and body posture on lower limb muscle activation among people with chronic stroke, and whether the EMG response to vibration stimulus differed between paretic and non-paretic side. The relationship between muscle activation and WBV transmission was examined. METHOD: Thirty-two participants with chronic stroke performed three different exercises on the WBV platform with different vibration conditions (frequency: 20 Hz, 30 Hz, 40 Hz; amplitude:0...

Total number of citations has been considered a proxy for a published study's importance within a given field. However, there are multiple pitfalls to correlating the total number of citations alone with the quality of a study. In this review, the authors aimed to identify the top 100 most-cited studies of hip and knee arthroplasty and then assess study design and quality of reporting. More than half of these studies were level IV evidence, unblinded, not randomized, and not controlled. This underscores the need for higher-quality study design to support practice...

A typical optical based gait analysis laboratory uses expensive stereophotogrammetric motion capture systems. The study aims to propose and validate an affordable gait analysis method using augmented reality (AR) markers with a single action camera. Image processing software calculates the position and orientation of the AR markers. Anatomical landmark calibration is applied on the subject to calibrate each of the anatomical points with respect to their corresponding AR markers. This way, anatomical points are tracked through AR markers using homogeneous coordinate transformations, and the further processing of gait analysis is identical with conventional solutions...

BACKGROUND: The term "floating" is used in orthopedic literature to describe certain patterns of skeletal injuries that share one common character which is disruption and discontinuity of bones above and below a joint. The first time used in orthopedic literature being in late 1970 to describe a type of elbow injury. Later the word was used increasingly and applied to a variety of injuries affecting the knee, shoulder, hip, forearm, hand, and ankle. Currently, there are about 12 different skeletal injuries described as floating...

Optimizing surgical instrumentation may contribute to value-based care, particularly in commonly performed procedures. We report our experience in implementing a perioperative efficiency program in 2 types of orthopedic surgery (primary total-knee arthroplasty, TKA, and total-hip arthroplasty, THA).A comparative before-and-after study with 2 participating surgeons, each performing both THA and TKA, was conducted. Our objective was to evaluate the effect of surgical tray optimization on operating and processing time, cost, and waste associated with preparation, delivery, and staging of sterile surgical instruments...

Ankle and knee injuries are two of the most common injuries. It has been shown that ankle sprains can lead to chronic ankle instability thereby affecting the function of the ankle. Since the lower extremity is a kinetic chain anything that affects the ankle is thought to affect the knee and hip as well. Changes in lower extremity function associated with chronic ankle instability may predispose patients for non-contact ACL injuries. The purpose of this study was to provide a systematic review of the research done on chronic ankle instability (CAI) and lower extremity kinematics during landing tasks...

BACKGROUND: To date, little is known about the characteristics of highly cited studies in hand surgery compared with other orthopaedic subspecialties. We aimed to assess the position of hand surgery within the orthopedic surgery literature. METHODS: We conducted a bibliographic analysis using the Web of Science database to review 1,568 articles published between January 2012 and December 2012 in 4 relevant general orthopedic and 2 hand surgery journals. We used the number of citations within 3 years of publication to measure the impact of each paper...
