Background: This study was done from January 2014 to July 2016, in 128 patients of knee joint osteoarthritis. We assessed epidemiology of osteoarthritis of knee and various MRI findings.Methods: In all the 128 patients radiographs (anteroposterior) were taken in extended and weight bearing position. Staging of osteoarthritis of knee was done using Kellgren-Lawrence scoring system and then we performed magnetic resonance imaging of the knee. All these patients were then interviewed about their clinical symptoms and osteoarthritis of knee was graded by WOMAC scale.Results: Osteoarthritis has a positive correlation with age, female sex and BMI. However occupation of the patient was not associated with any statistical significance. No association was seen between cartilage defects, bone marrow edema, sub chondral cysts, subchondral sclerosis, Baker’s cysts subluxations of tibia and synovitis with clinical features. The patellofemoral compartment of knee joint mostly contributed to the clinical symptoms of the patients in our study population though not being statistically significant (P >0. 05). In tibiofemoral compartment a statistically significant correlation was seen between most of the MRI findings and KL score, however in patellofemoral compartment this correlation is poor.Conclusions: Clinical findings and plain radiographs are still important in evaluating osteoarthritis of knee, MRI plays an important role in imaging the bony and soft tissues of knee as a whole organ, thereby helping in better management and outcome of the disease. Also MRI plays an important role in depicting early changes of osteoarthtis.
The infrapatellar fat pad of Hoffa is an intracapsular structure which is a common site for inflammatory processes. However, it can also be involved by neoplastic pathologies. We report a case of synovial hemangioma in this location which presented a diagnostic challenge due to unusual clinical presentation. The patient was managed with multiple sessions of ultrasound-guided injection sclerotherapy with partial resolution of the lesion.
Vascular disease is frequent in patients with systemic lupus erythematosus, which can be related to the disease process, or can develop as an accompanying co-morbidity and represents the most frequent cause of death in established disease. However, at times the presentations can be uncommon and subtle, and warrants a thorough examination both clinically and radiologically. We report a case of a young female with photosensitive malar rash, oral ulcers, intermittent fever with joint pains, history of two abortions, and unilateral absent radial and brachial artery pulses on clinical examination. The evaluation revealed positive antinuclear antibody (4+), anti-Smith antibody (2+), direct Coomb's test (2+), and antiphospholipid antibody panel was negative. Color doppler flow imaging of right upper limb (arterial) revealed irregular wall thickening with a narrow lumen and mildly reduced peak systolic volume. Computed tomography aortogram revealed wall thickening and luminal narrowing involving the entire length of the right brachial and radial artery. We report this case for its rarity and unique presentation of medium vessel vasculopathy.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
