Propionibacterium acnes has been described as an infrequent cause of periprosthetic joint infections, including those occurring at the knee [6-8], and has been found to be the most common etiologic agent in shoulder septic arthritis following rotator cuff repair [9] and arthroplasty [10]. However, P. acnes has only been described as an etiologic agent in native knee infection in a handful of ca...

BACKGROUND Septic arthritis is an infrequent disease although very important due to the possibility of disastrous outcomes if treatment is not adequately established. Adequate information concerning the epidemiology of septic arthritis is still lacking due to the uncommon nature of the disease as well as the struggle to establish a correct case-definition. OBJECTIVE To epidemiologically chara...

The causes of knee pain in patients with cancer with are different from those without cancer, and the purpose of this study was to evaluate these differences. Thirty-six patients with cancer who had knee pain who had undergone 1 or more modalities of treatment, including chemotherapy, radiotherapy, and bone marrow transplant, for a primary diagnosis of cancer were compared with a cohort of 40 p...

Pediatric septic arthritis is uncommon and has been traditionally treated by joint aspiration or open arthrotomy. There are some reports about arthroscopic surgery in pediatric septic arthritis of the knee, hip, and shoulder. However, there is no report for the case of elbow. We report a case of pediatric septic arthritis of elbow treated with arthroscopically with good clinical condition at 3-...

A 47-year-old patient presented with a chylous knee effusion and traumatic infected skin lacerations. The diagnosis of septic arthritis was considered because of purulent looking joint fluid, spuriously high synovial fluid white cell count, and signs of acute knee synovitis. Synovial fluid lipid analysis showed increased total lipids due to high concentration of neutral lipids, mainly triglycer...

We present a case of adult onset Still's disease (AOSD) that was misdiagnosed as septic arthritis of the shoulder and knee. A forty-nine-year-old woman was admitted for pain in the left knee. The patient's medical history showed that she had undergone arthroscopic irrigation twice and an open debridement under the diagnosis of septic shoulder at another hospital. The laboratory and joint fluid ...

Septic arthritis associated with extra-articular abscess is rare. We report on 2 non-rheumatic patients with septic arthritis of the knee associated with calf abscess. Magnetic resonance imaging showed a distinct leakage pathway from the knee joint in each patient. One was a ruptured popliteal cyst (posteromedial). Another was a pathologic popliteus hiatus (posterolateral). These patients under...

Septic arthritis is the most rapidly destructive joint disease, but its early diagnosis remains challenging; delayed or inadequate treatment, even by expert physicians, can lead to irreversible joint destruction. Between 25% and 50% of patients develop irreversible loss of joint function, which is especially concerning in elderly patients. To understand the factors influencing the outcome of se...

BACKGROUND Septic arthritis after arthroscopic anterior cruciate ligament reconstruction is a rare complication. In the literature, several different managements are proposed. HYPOTHESIS The graft can be retained during treatment of a septic arthritis after anterior cruciate ligament reconstruction. STUDY DESIGN Case series; Level of evidence, 4. METHODS A retrospective analysis of knee j...

Parvimonas micra is a rare pathogen for septic arthritis and is known for its subacute onset. We report a case of acute arthritis of the knee caused by P. micra and pseudogout. Initially, calcium pyrophosphate crystals were found in the knee, which were successfully treated with a steroid injection. Only anaerobic cultures became positive. A 16S rRNA PCR-analysis was necessary to identify P. mi...
