Knee trauma

Thi My Anh Tran, Beng Ghee Lim, Rohan Sheehy, Patricia L Robertson
INTRODUCTION: Common peroneal nerve (CPN) injury occurs in 10-40% of patients following knee dislocation. Is magnetic resonance imaging (MRI) using routine knee protocols able to adequately evaluate CPN injury and predict long-term outcome? METHODS: Trauma patients presenting for knee MRI at a single public hospital, between July 2007 and May 2017, were retrospectively identified using radiology and orthopaedic databases. Medical records were retrieved for clinical scores...

BACKGROUND: As the population ages, the developing world industrializes, and more urban centers emerge, the burden of orthopedic trauma will steadily increase. SIGN Fracture Care International has developed a unique intramedullary device for fixation of hip fractures in low-resource settings lacking fluoroscopy. The purpose of this study is to report the safety profile and complication rate for a consecutive series of hip fracture patients managed using this implant. METHODS: We conducted a retrospective analysis of the first 170 patients treated with the SIGN Hip Construct (SHC) from 2009 to 2014 using the SIGN Online Surgical Database (SOSD)...

The aim of this study was to assess the safety and efficacy of percutaneous low-energy osteotomy and casting in treatment of pathological coronal knee deformities in children equal or younger than 6 years. A prospective nonrandomized case series study was conducted. A total of 62 (109 limbs) patients with pathological coronal knee deformities were treated by percutaneous low-energy osteotomy and casting and observed over 3-10 years. The pathological nature was variable (rickets, Blount disease, dysplasia, after trauma, or after infection)...

Synovial plicae are thickenings of the synovial knee membrane; they are very frequent and often asymptomatic. However, they can become symptomatic due to idiopathic or secondary causes, as trauma and inflammation of the synovial tissue. Currently, synovial plicae are classified as infrapatellar, mediopatellar and suprapatellar. The prevalence of the mediopatellar plica over the other forms of plicae varies between 18% and 60%. The most reported symptom of the mediopatellar plica is pain located medial to the patella above the joint line...

INTRODUCTION: Three-dimensional (3D) surgical planning and patient-specific implants are becoming increasingly popular in orthopedics and trauma surgery. In contrast to the established and standardized alignment assessment on two-dimensional (2D) long standing radiographs (LSRs) there is neither a standardized nor a validated protocol for the analysis of 3D bone models of the lower limb. This study aimed to create a prerequisite for pre-operative planning. METHODS: According to 2D analysis and after meticulous research, 24 landmarks were defined on 3D bone models obtained from computed axial tomography (CT) scans for a 3D alignment assessment...

OBJECTIVE: Symptomatic distal interlocking screws in retrograde femoral nailing are common due the difficulties of imaging the trapezoidal femur. Screws appearing to have appropriate length on imaging may possibly be prominent, creating symptoms. Screw trajectory may influence the degree of this radiographic error. We hypothesize that external rotation of screw trajectory will increase measurement error of screw length. DESIGN: Retrospective. SETTING: Urban Level I Tertiary Trauma Center...

Cardiac rupture by blunt chest trauma is commonly seen after motor vehicle accidents and falls; however, it is rarely caused by a blow to the chest. We herein report an autopsy case of a high school boy who sustained severe right ventricular rupture by only one knee kick to the chest during a quarrel. He was hospitalized and developed cardiopulmonary arrest. Emergency surgery was performed, but the patient died. The autopsy revealed no external severe trauma or deformation, but the side wall of the right ventricle contained a large V-shaped laceration...

Venous thromboembolism (VTE) is a potentially fatal disease. Important risk factors of a provoked VTE are trauma, surgery or immobilization. Especially, patients who undergo hip and knee replacements are at high risk for postoperative VTE. We aimed to compare in-hospital VTE burden and other outcomes after upper and lower extremity endoprosthetic surgeries in Germany. The nationwide German inpatient sample of the years 2005-2015 was used for data analysis. Patients who underwent endoprosthetic joint/bone replacements of the extremities (OPS codes 5-820, 5-822, 5-824 and 5-826) were further stratified in those operated on lower (OPS codes 5-820, 5-822 and 5-826) or upper extremity (OPS code 5-824) joints...

This review examines risks that accompany child and adolescent participation in downhill skiing. Falls and non-collision events were the most common mechanism of injury, but significant data implicate head injuries, blunt abdominal trauma, and spinal trauma as the leading causes of morbidity and mortality in this population. School-aged children and youth (7-14 years) are more likely to sustain an injury, compared to children (0-6 years) and older teenagers (15-17 years). Knee injuries were the most common injury, reported as 10...

Diagnosis in prosthetic joint infections is challenging as symptoms are variable, and currently most of the diagnostic tests are non-specific. Normal inflammatory reactions after orthopedic prosthetic surgery may generate false positives, as these tests have high sensitivity but low specificity. Thus, specific tests, as alpha defensin, are needed to distinguish bacterial infections from reactions to surgical trauma. The aim of this study was to determine the sensitivity and specificity of several diagnostic tools for detecting bacterial infection in prostheses...

With average life expectancy and the rising prevalence of obesity, osteoarthritis (OA) is creating an increasingly large financial and physical burden on the U.S. population today. As the body ages and experiences trauma, articular cartilage surfaces in joints are gradually worn away, leading to OA. Traditionally, treatment options have included lifestyle modifications, pain management, and corticosteroid injections, with joint replacement reserved for those who have exhausted nonsurgical measures. More recently, hyaluronic acid, micronized dehydrated human amniotic/chorionic membrane tissue, and platelet-rich plasma (PRP) injections have started to gain traction...

BACKGROUND: Patellofemoral pain is one of the most common forms of knee arthralgia in adolescent females. Unlike in adults, in whom the etiology of patellofemoral pain is considered to be multifactorial (eg, altered bone shape and musculoskeletal dynamics), the etiology of adolescent patellofemoral pain has been historically attributed to overuse. Although it is highly plausible that adolescent patellofemoral pain results from excessive maltracking, as suggested by recent research, an increase in patellar, relative to femoral, size could also contribute to patellofemoral pain through altered cartilage stresses/strains, resulting in overloading of the subchondral bone...

BACKGROUND: In mass casualty incidents (MCI), death usually occurs within the first few hours and thus early transfer to a trauma centre can be crucial in selected cases. However, most triage systems designed to prioritize the transfer to hospital of these patients do not assess the need for surgery, in part due to inconclusive evidence regarding the value of such an assessment. Therefore, the aim of the present study was to evaluate the capacity of a new triage system-the Prehospital Advanced Triage Method (META)-to identify victims who could benefit from urgent surgical assessment in case of MCI...

CONTEXT: Knee arthroplasty surgery is significant trauma, leading to an activated immune system causing inflammation and oxidative stress. Many current biomarkers are invasive, costly, and often slow to analyse, limiting their use for rapid inflammatory measurements. OBJECTIVES: We have examined the use of urinary neopterin and total neopterin in knee arthroplasty patients to non-invasively measure oxidative stress and inflammation from immune system activation...

The term "idiopathic calcifying tenosynovitis" (ICT) refers to a clinically and radiologically defined syndrome of pain and tendinous calcifications, most often involving the shoulder joint. A distinctive subset of ICT cases, termed "tenosynovitis with psammomatous calcifications" (TPC), occurs in the distal extremities and shows characteristic morphology, in particular psammomatous calcifications. As only 14 cases have been reported to date, TPC remains poorly recognized by both pathologists and clinicians...
