Tranexamic acid (TA) is widely used by orthopedic surgeons to decrease blood loss and the need for transfusion following total hip arthroplasty (THA). Although both intravenous and topical applications are described in the literature, there remains no consensus regarding the optimal regimen, dosage and method of delivery of TA during THA. In addition, concerns still exist regarding the risk of thromboembolic events with intravenous administration. The purpose of this meta-analysis was to compare the efficacy and safety of topical versus intravenous administration of TA in THA...

The aim of our study is to evaluate the clinical and radiologic outcomes in patients with terrible triad injury, who underwent surgical treatment with or without the medial collateral ligament (MCL) repair. Fourteen patients who underwent surgery with a minimum of 12-month follow-up (mean, 17 months) were reviewed. Based on the systematic treatment protocol, radial head fracture, lateral collateral ligament, and coracoid fracture were treated. Subsequently, torn MCL was repaired in 7 patients, whereas in the remaining 7 patients, the MCL was not treated...

There has been great interest in bone marrow aspirate concentrate (BMAC) as a cost effective method in delivering mesenchymal stem cells (MSCs) to aid in the repair and regeneration of cartilage defects. Alongside MSCs, BMAC contains a range of growth factors and cytokines to support cell growth following injury. However, there is paucity of information relating to the basic science underlying BMAC and its exact biological role in supporting the growth and regeneration of chondrocytes. The focus of this review is the basic science underlying BMAC in relation to chondral damage and regeneration...

Increasing emphasis on maintaining a healthy lifestyle has led many individuals to seek advice on exercise from personal trainers. There are few studies to date that evaluate personal trainer education, practice trends, and injuries they have seen while training clients. A survey was distributed to personal trainers using Survey Monkey® (Palo Alto, CA, USA) with 605 personal trainers accessing the survey. An exercise related bachelor's degree was held by 64.2% of survey participants and a certification in personal training by 89...

Hereditary multiple exostosis (HME) is an autosomal dominant disorder characterized by two or more benign growing, cartilage capped tumors of long bones called osteochondromas. If abnormal growth and clinical symptoms of osteochondromas newly appear in adults, malignant transformation of the usually benign growing tumors should be suspected and diagnostic testing should be initiated. Against the background of hypothesized higher malignant transformation of osteochondromas into chondrosarcoma in individuals with shoulder exostoses, we report a case of bilateral scapulothoracic osteochondromas in a patient suffering from HME...

Magnesium-based interference screws may be an alternative in anterior/posterior cruciate ligament reconstruction. The well-known osteoconductive effects of biodegradable magnesium alloys may be useful. It was the purpose of this study to evaluate the biomechanical properties of a magnesium based interference screw and compare it to a standard implant. A MgYREZr-alloy interference screw and a standard implant (Milagro®; De Puy Mitek, Raynham, MA, USA) were used for graft fixation. Specimens were placed into a tensile loading fixation of a servohydraulic testing machine...

We examined our experience and, in particular, complications associated with total hip arthroplasty in obese and morbidly obese patients. We prospectively gathered 50 patients in a matched control series including 25 obese and morbidly obese patients. All patients were operated using the direct lateral approach and standard postoperative protocols. Operating room time, complications, dislocations, blood loss, cup position and clinical parameters using the Harris Hip Score and the Western Ontario and McMaster Universities Arthritis Index results were compared...

In case of patients with spinal cord injury and concomitant acromioclavicular (AC) joint-dislocation the treatment is challenging, as in this special patient group the function of the shoulder joint is critical because patients depend on the upper limb for mobilization and wheelchair-locomotion. Therefore the goal of this study was to examine, if the treatment of chronic AC-joint dislocation using the Weaver-Dunn procedure augmented with a hook-plate in patients with a spinal cord injury makes early postoperative wheelchair mobilization and the wheelchair transfer with full weight-bearing possible...

Knee osteoarthritis is a leading cause of disability around the world. Knee bracing provides a conservative management option for symptom relief. A variety of different bracing types, manufacturers and products are currently available on the market. The goal of this study is to examine the current state of the literature regarding the treatment of knee osteoarthritis with unloader bracing, specifically examining the representation of specific brace types, manufacturers and models within the literature. A scoping review technique was used because of its ability to evaluate research activity within an area of study and identify gaps within the literature...

A common treatment of tibial defects especially after infections is bone transport via external fixation. We compare complications and outcomes of 25 patients treated with a typical Ilizarov frame or a hybrid system for bone reconstruction of the tibia. Average follow up was 5.1 years. Particular interest was paid to the following criteria: injury type, comorbidities, development of osteitis and outcome of the different therapies. The reason for segmental resection was a second or third grade open tibia fractures in 24 cases and in one case an infection after plate osteosynthesis...

Sport specific movements coming along with characteristic plantar pressure distribution and a fatigue of muscles result in an increasing postural sway and therefore lead to a decrease in balance control. Although single soccer specific movements were expatiated with respect to these parameters, no information is available for a complete training session. The objective of the present observational study was to analyze the direct influence of soccer training on postural stability and gait patterns and whether or not these outcomes were altered by age...

Xinning Li, Phillip Williams, Emily J Curry, Jo A Hannafin
Two elite female athletes presented with anterior knee pain with range of motion and reproducible tenderness to palpation. Diagnostic arthroscopy was performed in both cases resulting in excision of a nodular pigmented villonodular synovitis (PVNS) in the first patient and scar tissue in the second patient. Correct diagnosis of anterior knee pain in the elite female athlete can present a challenge to clinicians. Although patellofe-moral pain is the most common diagnosis, other uncommon causes include PVNS and residual scar formation in patients with a history of surgery or trauma...

Dislocation of the hip is a well-described event that occurs in conjunction with high-energy trauma or postoperatively after total hip arthroplasty. Bigelow first described closed treatment of a dislocated hip in 1870, and in the last decade many reduction techniques have been proposed. In this article, we review all described techniques for the reduction of hip dislocation while focusing on physician safety. Furthermore, we introduce a modified technique for the reduction of posterior hip dislocation that allows the physician to adhere to the back safety principles set for by the Occupational Safety and Health Administration...

UNLABELLED: The valgus-impacted (VI) 4-part fractures are a subset of fractures of the proximal humerus with a unique anatomic configuration characterized by a relatively lower incidence of avascular necrosis after operative intervention. We systematically reviewed clinical studies assessing the benefits and harms of least possible fixation techniques (LPFT) for this unique fracture type. Such information would be potentially helpful in developing an evidence-based approach in the management of these complex injuries...
