Kocher Criteria In 1999, Mininder S. Kocher, a pediatric orthopedic surgery fellow at Harvard, developed an interest in determining if there were certain variables of a child's presentation that would allow for a more accurate differentiation of these two diseases Background: The early diagnosis of pediatric septic arthritis is paramount to the prevention of long-term sequela. The purpose of this study is to investigate if the commonly used criteria developed by Kocher and colleagues for hip septic arthritis can be used for screening children with suspected septic knee Kocher criteria can help to differentiate between spetic arthritis and transient synovitis in a case of non-traumatic painful hip in a child The Kocher criteria can be applied to all pediatric patients with an acutely irritable hip for whom SA and TS are in the differential diagnosis. Next Steps A thorough history and physical examination should be obtained for all pediatric patients who present with an acutely irritable hip
The Kocher Criteria for Septic Arthritis distinguishes septic arthritis from transient synovitis in a child with an inflamed hip. Determine risk of septic arthritis in a child with an inflamed hip or product information in the various section in the website does not constitute an endorsement or approval by Pediatric Oncall of the quality or. They are known as the Kocher criteria,for Dr. Mininder S. Kocher, associate di-rector of sports medicine at Children'sHospital Boston. He was first author ofthe study that introduced the criteriaand an associated evidence-based, pre-dictive algorithm Interestingly, the Kocher criteria does not include CRP as at the time of the study, Boston Children's Hospital could only test CRP weekly so only about 40% of the participants of the validation study had a documented CRP. Today, it is common to use CRP in addition to serum WBC and ESR when working up a patient for septic arthritis Application of the Kocher criteria, when all four criteria were filled, resulted in an 80% positive-predictive value (PPV) (Table 1). An elevated CRP (2.0mg/dL) and inability to bear weight together resulted in a PPV of 78%. With a CRP threshold of 3.0mg/dL and inability to bear weight, the PPV was 81% (Table 2) The Kocher criteria for septic arthritis has proved its specificity in diagnosing or ruling out SA for the extreme scores. About the study The original study was conducted by Kocher et al. on a cohort of patients evaluated at a major tertiary-care children's hospital between 1979 and 1996
Septic Arthritis: Kocher's Criteria. In 1999, Kocher et al published retrospective data from cases that presented to their facility from 1979-1996 due to acutely irritable hip. Through a logistic regression analysis of 168 patients, they devised a probability algorithm to help differentiate between septic arthritis and toxic synovitis The Kocher score was retrospectively derived by Kocher et al. in 1999 as a way to help clinicians differentiate between septic arthritis and transient tenosynovitis in pediatric patients with inflamed hips. The original study included 282 patients of which 82 were eventually diagnosed with septic arthritis based on joint fluid analysis Kocher Criteria. The Kocher criteria, a previously validated clinical prediction rule used for the initial evaluation of patients with irritable hip, includes the following 4 predictors: inability to bear weight on the affected limb, presence of fever (documented temperature ≥38.5°C), peripheral WBC count ≥12 000 cells per mm 3, and ESR. The Kocher criteria are a tool useful in the differentiation of septic arthritis from transient synovitis in the child with a painful hip. They are named for Mininder S. Kocher, an orthopaedic surgeon at Boston Children's Hospital and Professor of Orthopaedic Surgery at Harvard Medical School Key Words: MRI, osteomyelitis, septic arthritis, children, ultrasound, Kocher criteria (J Pediatr Orthop 2017;37:e114-e119) The Kocher criteria are established clinical parameters, which include fever (temperatureZ38.51C), inability to bear weight, white blood cell (WBC) count >12.0 109cells/L, and erythrocyte sedimentation rat

Kocher criteria for pediatric septic hip The Kocher criteria are useful for distinguishing between septic arthritis and transient synovitis in a child presenting with a painful hip. The criteria are as follows: 1. Non-weight-bearing on affected side 2. ESR > 40 mm/h Kocher et al. published criteria to differentiate between a septic hip and transient synovitis of the hip (see Kocher Criteria). A low WBC or platelet count raises suspicion for leukemia, prompting a peripheral smear. Remember, no pathognomonic lab tests exist to diagnose rheumatic diseases, and even a child who has multiple swolle The Kocher criteria can be used to assist with diagnosis of septic arthritis of the hip. The four criteria are as follows: a history of fever over 38.5 degrees Celsius, an inability to bear weight on the affected extremity, an ESR greater than 40 mm/hr, and WBC greater than 12,000 cells/microliter . The four elements include: Erythrocyte sedimentation rate >40. WBC >12. Non-weight bearing on the affected joint. Fever >38.5 C Kocher Criteria (continued) Caird et al, 2006: Prospective cohort study of 48 patients evaluated between 2000 and 2003 at a major tertiary-care children's hospital presenting with an acutely irritable hip who underwent hip aspiration. 34 children were diagnosed with septic arthritis; 14 children were diagnosed with transient synovitis
The Kocher criteria for predicting septic arthritis gives increasing probability for each of the following criteria met [Kocher et al. J Bone Joint Surg-Am] 2004:86;1629. Non-weight-bearing on affect side; ESR > 40 mm/hr; Fever; WBC >12,000; The Kocher rule is helpful to rule-in higher pre-test probability patients. Fever is probably the best. 1. Martin J.

VAIL, COLO. - Four simple criteria are useful in distinguishing septic arthritis from transient synovitis in a child with an inflamed hip. The criteria are known as the Kocher criteria, for Dr. Mininder S. Kocher, associate director of sports medicine at Children's Hospital Boston, who was first author of the study that introduced the criteria and an associated evidence-based, predictive.
Although first introduced in 1999, more recent studies have validated its continued usefulness in the evaluation of SA. 10,11 Components of the Kocher criteria are: (1) walking or weight-bearing inability, (2) fever greater than 38.5 °C (101.3 °F), (3) ESR greater than 40 mm/hr, and (4) WBC greater than 12,000 cells/L. A point is awarded. The rate of presentation to the emergency department with an atraumatic limp is approximately 1.4 per 1000 in children under the age of 14. It occurs more often in boys than in girls ( 1.7:1) and the median age is 4.4 years. When we consider the potential causes the list is massive . The newer FeverPAIN Score is similar, but the Centor Score has the distinguishes between adolescents and young adults from pre-adolescents—important because. The Kocher criteria have proven to be helpful in making the distinction between these two conditions, and they are reviewed in this article. In addition, imaging studies, especially hip ultrasound, are extremely helpful in the evaluation of the painful hip Kocher criteria for pediatric septic hip. The Kocher criteria are useful for distinguishing between septic arthritis and transient synovitis in a child presenting with a painful hip. The criteria are as follows: 1. Non-weight-bearing on affected side 2. ESR > 40 mm/h

In their original paper in 1999, Dr Kocher et al. performed a retrospective analysis of children who were being evaluated for a septic joint versus transient synovitis over a 15 year period, in a major referral center. They came up with four independent predictors of a septic joint, and calculated the probability of septic arthritis based on the number of features present Kocher Criteria for Septic Arthritis in Children: Septic arthritis should be suspected in children that have a painful joint especially if they do not want to weight bear. Orthopedics uses the Kocher Criteria to determine the probability of whether the joint is infected. Four elements make up the criteria: Erythrocyte Sedimentation Rate >40. The knee is the joint most commonly imaged with MRI in the pediatric population. Common indications include assessment of internal derangement, pain, and further investigation of a radiographic abnormality. Although overlap between pediatric and adult pathology exists, particularly in the group of adolescents who have fused growth plates, there. A clinical scale used to assess pre-test probability of septic arthritis is the Kocher criteria.1. 1) Non-weight bearing on affected side, 2) ESR >40, 3) Fever >38.5 C, 4)WBC count of >12,000. Based on the number of criteria present determines the risk of septic arthritis: 1 out of 4= 3%; 2 out of 4= 40%; 3 out of 4= 93%; 4 out of 4= 99%
