Aspirations Of A Troubled Knee - Page #3
 

Lab Studies:
Due to the swelling, we obtained an in-office ultrasound which showed a significant effusion in the suprapatellar pouch. Case Photo #5 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.

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.
