And Oxidative Stress

Osteoarthritis (OA) is the most frequently diagnosed joint disorder worldwide with increasing prevalence and crucial impact on the quality of life of affected patients through chronic pain, decreasing mobility and invalidity. Although some risk factors, such as age, obesity and previous joint injury are well established, the exact pathogenesis of OA on a cellular and molecular level remains less understood. Today, the role of nitrosative and oxidative stress has not been investigated conclusively in the pathogenesis of OA yet. Therefore, the objective of this study was to identify biological substances for oxidative and nitrosative stress, which mirror the degenerative processes in an osteoarthritic joint. 69 patients suffering from a diagnosed knee pain participated in this study. Based on the orthopedic diagnosis, patients were classified into an osteoarthritis group (OAG, n=24) or in one of two control groups (meniscopathy, CG1, n=11; anterior cruciate ligament rupture, CG2, n=34). Independently from the study protocol, all patients underwent an invasive surgical intervention which was used to collect samples from the synovial membrane, synovial fluid and human serum. Synovial biopsies were analyzed histopathologically for synovitis (Krenn-Score) and immunohistochemically for detection of end products of oxidative (8-isoprostane F2α) and nitrosative (3-nitrotyrosine) stress. Additionally, the fluid samples were analyzed for 8-isoprostane F2α and 3-nitrotyrosine by competitive ELISA method. The analyzation of inflammation in synovial biopsies revealed a slight synovitis in all three investigated groups. Detectable concentrations of 3-nitrotyrosine were reported in all three investigated groups without showing any significant differences between the synovial biopsies, fluid or human serum. In contrast, significant increased concentrations of 8-isoprostane F2α were detected in OAG compared to both control groups. Furthermore, our data showed a significant correlation between the histopathological synovitis and oxidative stress in OAG (r=0.728, P<0.01). There were no significant differences between the concentrations of 8-isoprostane F2α in synovial fluid and human serum. The findings of the current study support the hypothesis that oxidative and nitrosative stress are components of the multi-factory pathophysiological formation of OA. It seems reasonable that an inflammatory process in the synovial membrane triggers the generation of oxidative and nitrosative acting substances which can lead to a further degradation of the articular cartilage. Based on correlations between the observed degree of inflammation and investigated biomarkers, especially 8-isoprostane F2α seems to be a novel candidate biomarker for OA. However, due to the finding that also both control groups showed increased concentrations of selected biomarkers, future studies have to validate the diagnostic potential of these biomarkers in OA and in related conditions of the knee joint.

AbstractThe authors report a case of popliteal cyst which was detected during the routine dissection of a cadaver in Anatomy Department, Government Medical College, Thrissur, Kerala. The cyst was identified in the right popliteal fossa in a female cadaver arising from the interior of knee joint. It measured 6 cm in length and 3 cm in width. Thick synovial membrane was forming the cyst wall. On deep dissection it was found communicating directly with the synovial lining of knee joint.

Seven healthy mature rabbits were used to study both the surface morphology of the meniscus using both transmission electronmicroscopy (TEM) and scanning electronmicroscopy (SEM) and articular cartilage of the femoral condyle using SEM. Results showed that the membrane covering the meniscus was structurally the extension of synovial membrane of the knee joint capsule. Additionally, the presence of canal-like openings over the membranous surface to the meniscus was noted, which were absent over the articular cartilage surface. Key words: transmission and scanning electronmicroscopy, meniscus, articular cartilage, rabbits

The lipoma arborescent of the knee consists of a benign villonodular proliferation of fat under the synovial membrane. It is a rare entity often secondary to previous trauma. Hoffa's fat is an extrasynovial intracapsular fat pad that which looks like a quadrangular pyramid is in the anterior-inferior compartment of the knee joint. The case of a 44-year-old male patient is presented, professional trainer, who complains of pain and increased volume of the anterolateral region of the right knee. Arborescent lipoma of Hoffa's fat is diagnosed. Key words: lipoma arborescent, Hoffa fat, knee lipoma, benign Hoffa fat tumor
