Synovial Fluid and Serum Neutrophil-to-Lymphocyte Ratio: Novel Biomarkers for the Diagnosis and Prognosis of Native Septic Arthritis in Adults.

J Bone Joint Surg Am 2022 Jun 20. Epub 2022 Jun 20.

Department of Orthopaedic Surgery, Brigham and Women's Hospital, Harvard Medical School, Boston, Massachusetts.

Background: Septic arthritis (SA) is a musculoskeletal emergency for which prompt diagnosis and treatment are critical. However, traditional diagnostic criteria of a synovial fluid (SF) white blood-cell count (WBC) of >50,000 cells/mm3 or >90% polymorphonuclear leukocytes (%PMN) are not particularly sensitive or specific for the diagnosis of SA. Furthermore, prognostic markers are lacking. Read More

Scurvy: a rare cause of haemarthrosis.

BMJ Case Rep 2022 Mar 7;15(3). Epub 2022 Mar 7.

Department of Internal Medicine, UT Southwestern Medical Center, Dallas, Texas, USA

A male in his 60s with a history of previously treated locally advanced head and neck cancer presented to the emergency department with atraumatic left knee pain and upper and lower extremity ecchymoses that had been present for 3 weeks. His initial laboratory results showed a normocytic anaemia, normal platelet count, slightly abnormal coagulation studies and normal inflammatory markers. Arthrocentesis of the left knee revealed haemarthrosis, and additional laboratory workup found an undetectable serum vitamin C (ascorbic acid) level consistent with scurvy. Read More

Recent Antibiotic Treatment Impacts Serum and Synovial Laboratory Values in Early Periprosthetic Joint Infection Workup.

J Arthroplasty 2022 06 22;37(6S):S286-S290. Epub 2022 Feb 22.

Department of Orthopedic Surgery, Mayo Clinic, Rochester, Minnesota.

Background: Accurately detecting early postoperative periprosthetic joint infection (PJI) following total hip arthroplasty (THA) and total knee arthroplasty (TKA) remains challenging. The purpose of our study was to determine the impact of antibiotics given prior to laboratory evaluation on the reliability of serologic and synovial fluid tests to identify PJI in the early postoperative period.

Methods: We identified 49,861 primary total hip arthroplasties and total knee arthroplasties performed between 2000 and 2019. Read More

Foot Ankle Surg 2022 Feb 18. Epub 2022 Feb 18.

Schön Klinik München Harlaching - FIFA Medical Centre, 81547 Munich, Germany.

Background: There is little valid data available on managing infected total ankle arthroplasty (TAA).

Methods: A single-center, retrospective evaluation from 20 patients with PJI (periprosthetic joint infection) of the ankle compared the bacteria isolated by preoperative arthrocentesis and intraoperative cultures to the pathogens of knee PJI. Long-term failure rates of irrigation and debridement (I&D) and polyethylene exchange, revision arthroplasty, and arthrodesis were analyzed. Read More

Randomized Controlled Study of a Training Program for Knee and Shoulder Arthrocentesis on Procedural Simulators with Assessment on Cadavers.

ACR Open Rheumatol 2022 Apr 6;4(4):312-321. Epub 2022 Jan 6.

University of Caen Normandy, Caen, France.

Objective: The study objective was to assess the efficacy of simulators in improving the competence of students in performing a knee and shoulder arthrocentesis on cadavers and to determine the minimum number of simulator training procedures needed to achieve competence in arthrocentesis.

Methods: Two groups of 15 medical students were each trained to perform a single joint arthrocentesis ("knee group" and "shoulder group") on a simulator to serve as a control for the other. The two groups received the same theoretical training (anatomy, arthrocentesis techniques, ultrasound, and hybrid simulation). Read More

Enhanced arthrocentesis of the effusive knee with pneumatic compression.

Int J Rheum Dis 2022 Mar 4;25(3):303-310. Epub 2022 Jan 4.

Department of Internal Medicine, Division of Rheumatology, University of New Mexico Health Sciences Center, Albuquerque, New Mexico, USA.

Aim: Complete arthrocentesis of the effusive knee ameliorates patient pain, reduces intra-articular and intraosseous pressure, removes inflammatory cytokines, and has been shown to substantially improve the therapeutic outcomes of intra-articular injections. However, conventional arthrocentesis incompletely decompresses the knee, leaving considerable residual synovial fluid in the intra-articular space. The present study determined whether external pneumatic circumferential compression of the effusive knee permitted more successful arthrocentesis and complete joint decompression. Read More

Intra-articular venous malformations of the knee: a diagnostic challenge.

Pediatr Rheumatol Online J 2021 Oct 13;19(1):153. Epub 2021 Oct 13.

UOSD Reumatologia e Immunologia Pediatrica, Ospedale Vito Fazzi, Lecce, Italy.

Background: Intra-articular venous malformations (IAVM) are rare benign vascular anomalies that usually affect young patients and most common locate in the knee. The terminology of these lesions is still ill-defined, as they are often termed in the literature as synovial hemangiomas. Early diagnosis can be difficult, because they usually present with nonspecific clinical manifestations that are similar those of other rheumatic diseases, especially juvenile idiopathic arthritis (JIA).

Pharmacoepidemiol Drug Saf 2021 09 5;30(9):1184-1191. Epub 2021 Jul 5.

Division of Infectious Diseases, Department of Medicine, Perelman School of Medicine, University of Pennsylvania, Philadelphia, Pennsylvania, USA.

Purpose: To determine the positive predictive values (PPVs) of ICD-9, ICD-10, and current procedural terminology (CPT)-based diagnostic coding algorithms to identify prosthetic joint infection (PJI) following knee arthroplasty (TKA) within the United States Veterans Health Administration.

Methods: We identified patients with: (1) hospital discharge ICD-9 or ICD-10 diagnosis of PJI, (2) ICD-9, ICD-10, or CPT procedure code for TKA prior to PJI diagnosis, (3) CPT code for knee X-ray within ±90 days of the PJI diagnosis, and (4) at least 1 CPT code for arthrocentesis, arthrotomy, blood culture, or microbiologic procedure within ±90 days of the PJI diagnosis date. Separate samples of patients identified with the ICD-9 and ICD-10-based PJI diagnoses were obtained, stratified by TKA procedure volume at each medical center. Read More
