RESUMO

The acute locked knee is an orthopaedic emergency requiring prompt diagnosis and treatment. It can be classified as acute or chronic. The term 'locked knee' refers to a knee that demonstrates fixed flexion or which has a 'block' to complete extension. Some degree of active or passive extension may be achievable, but not full extension. The most frequent causes of a locked knee are a meniscal tear, rupture of the anterior cruciate ligament or loose bodies. Magnetic resonance imaging is the gold standard in diagnostic imaging. Knee arthroscopy is considered the gold standard in management. This article gives an overview of the presentation, assessment and management of the locked knee for core surgical, acute care common stem and emergency medicine trainees.

RESUMO

INTRODUCTION: Knife crime remains an area of public health concern. In order to tackle this problem and reduce its burden, the epidemiology of penetrating knife injuries needs to be understood. The aim of this study is to analyse the pattern of knife injuries at a major trauma centre (MTC) in London. METHODS: An analysis of cases from the prospectively collected Trauma Audit and Research Network database of patients attending the emergency department with violent intentional knife injuries from January 2014 to December 2018 was performed. Registry data were analysed for mechanism of injury, number of stabbings, month/date/time of admission, patient demographics, anatomical pattern of injury, hospital length of stay, intervention, ethnicity, repeat victims and fatality. RESULTS: 1373 penetrating knife injuries activated the major trauma call representing 11.7% of all major trauma alerts. 44% occurred in the 16-25 years age group and 85.6% were male. 67.2% required hospital admission. 14.1% required surgery. 50.3% required intervention from multiple specialities. 39.4% had thoracic injuries and 25.8% abdominal injuries. Fatality rate was 0.9% (n=12). 3.6% were repeat victims. 26.8% were multiple stabbings. 5.2% were deliberate self-harm. 23.2% were of white ethnic background. Injury incidence peaked on a Saturday. A significant peak in injuries occurred between 22:00 and 00:00. CONCLUSION: This study shows an increase in the incidence of knife crime per year. These cases contribute approximately 12% of major trauma calls. Female assaults increased from 8.4% to 14.3%. Approximately 2/3 injuries occur in the thorax and abdomen with high frequencies at weekends and evenings. These facts can help allocate resources more efficiently.

RESUMO

INTRODUCTION: Tibial shaft fractures are common fractures seen in trauma and orthopedic practice today. The majority of these fractures are treated with intramedullary nailing (IMN) which is rapidly becoming a gold standard. The procedure itself is performed by either a suprapatellar approach or infrapatellar approach. Suprapatellar approach is gaining popularity due to relative ease of insertion, decreased associated risk of anterior knee pain, and more accurate reduction. We report a case of heterotopic ossification noted in the knee following IMN of tibia performed using a suprapatellar approach. CASE REPORT: A 27-year-old male, having sustained a left, Gustilo IIIB tibial shaft fracture following a motor vehicle accident, underwent a reamed intramedullary nail fixation performed through a suprapatellar approach. Two months later, he presented with intra-articular heterotopic ossification which was limiting his knee movement. He then underwent arthroscopic removal of the bony fragments which resolved his symptoms. CONCLUSION: An extensive search of literature did not yield any reported incidence of heterotopic ossification associated with IMN performed through a suprapatellar approach. We present this case report to raise awareness that although IMN through a suprapatellar approach is a safe approach, it does have associated risk of heterotopic ossification which needs to be included in the consent process.

RESUMO

BACKGROUND: Chondral delamination with intact articular surface is an under-recognised entity with no previous reports on how it should be managed. The purpose of this article is to increase awareness of this entity and make recommendations for its management. METHODS: We present a small case series of three patients who presented with knee pain and subsequent MRI scans revealed chondral delamination with intact articular surface as the only explanation of symptoms. RESULTS: Two of the lesions were located in the patella and one on the lateral aspect of the medial femoral condyle. All three were treated with bioabsorbable pin fixation. The delaminated area was easily recognised at arthroscopy by its bogginess on probing. All three patients made an excellent recovery and the lesions healed on MRI. CONCLUSION: Chondral delamination with intact articular surface is best managed with bioabsorbable pin fixation so that it can be salvaged in order to optimise patient outcomes and avoid deterioration to a full thickness chondral lesion once the articular surface has separated.

RESUMO

Prevention of extremity war wound infection remains a clinical challenge. Staphylococcus aureus is the most common pathogen in delayed infection. We hypothesised that choice of wound dressings may affect bacterial burden over 7 days reflecting the current practice of delayed primary closure of wounds within this timeframe. A randomised controlled trial of 3 commercially available dressings (Inadine(®) (Johnson & Johnson, NJ, USA), Acticoat(®) (Smith & Nephew, Hull, UK), Activon Tulle (Advancis Medical, Nottingham, UK)) was conducted in a rabbit model of contaminated forelimb muscle injury. A positive control group treated with antibiotics was included. Groups were compared to a saline soaked gauze control. The primary outcome was a statistically significant reduction (p < 0.05) in tissue S. aureus at 7 days post-injury. Secondary outcome measurements included bacteraemias, observational data, whole blood determination, ELISA for plasma biomarkers, PCR array analysis of wound healing gene expression and muscle/lymph node histopathology. Antibiotic, Inadine and Acticoat groups had statistically significant lower bacterial counts (mean 7.13 [95% CI 0.00-96.31]×10(2); 1.66 [0.94-2.58]×10(5); 8.86 [0.00-53.35]×10(4)cfu/g, respectively) and Activon Tulle group had significantly higher counts (2.82 [0.98-5.61]×10(6)cfu/g) than saline soaked gauze control (7.58 [1.65-17.83]×10(5)cfu/g). There were no bacteraemias or significant differences in observational data or whole blood determination. There were no significant differences in muscle/loss or pathology and lymph node cross-sectional area or morphology. There were some significant differences between treatment groups in the plasma cytokines IL-4, TNFα and MCP-1 in comparison to the control. PCR array data demonstrated more general changes in gene expression in the muscle tissue from the Activon Tulle group than the Inadine or Acticoat dressings with a limited number of genes showing significantly altered expression compared to control. This study has demonstrated that both Acticoat(®) and Inadine(®) dressings can reduce the bacteria burden in a heavily contaminated soft tissue wound and so they may offer utility in the clinical setting particularly where surgical treatment is delayed.
