Lab Studies:
Due to the swelling, we obtained an in-office ultrasound which showed a significant effusion in the suprapatellar pouch. <a href="CaseStudyImages/CS5CS4CS3CS2Aspirati-651.jpg" title="Case Photo #5" data-lity><b>Case Photo #5</b></a> We aspirated 48cc of clear, straw colored, non-purulent fluid. This fluid was collected and sent for culture, which remained in the lab for 3 weeks without the growth of any organisms.
Other Studies:
In-office X-rays were obtained which showed well preserved joint spaces, normal bony alignment, and no fractures or masses seen.

<br>MRI was obtained two weeks after initial aspiration and conservative treatment, due to reaccumulating fluid and additional pain. MRI showed a large joint effusion with a 3.8cm x 2.4cm x 2.5cm mass-like lesion that indented the posterior-superior margin of Hoffas fat pad and extended posterior to the lower pole of the patella. <a href="CaseStudyImages/CS6CS5CS4CS3CS2Aspir-651.jpg" title="Case Photo #6" data-lity><b>Case Photo #6</b></a> <a href="CaseStudyImages/CS7CS6CS5CS4CS3CS2As-651.jpg" title="Case Photo #7" data-lity><b>Case Photo #7</b></a> <a href="CaseStudyImages/CS8CS7CS6CS5CS4CS3CS-651.jpg" title="Case Photo #8" data-lity><b>Case Photo #8</b></a>
