    Summary
    This summary is machine-generated.

    Increased patellar uptake on bone scans, often called a "hot" patella, is common. This study identifies various causes, including osteoarthritis and fractures, highlighting the need for clinical correlation.

    Area of Science:

    • Radiology
    • Nuclear Medicine
    • Orthopedics

    Background:

    • Bone scintigraphy is a common imaging modality.
    • Increased radiotracer uptake in the patella is a frequent finding.
    • Etiologies for increased patellar uptake are not well-established.

    Observation:

    • A review of 100 bone scans was conducted.
    • The incidence of bilateral "hot" patellae was found to be 15% in this cohort.
    • Various potential causes were identified.

    Findings:

    • Osteoarthritic degenerative disease was the most common etiology (35%).
    • Other identified causes include fracture, metastatic disease, bursitis, Paget's disease, and osteomyelitis.
    • A significant percentage of "hot" patellae have identifiable underlying pathologies.

    Implications:

    • Increased patellar uptake on bone scans warrants thorough investigation.
    • Clinical history, physical examination, and radiography are crucial for accurate diagnosis.
    • Understanding these etiologies improves diagnostic accuracy in nuclear medicine and orthopedics.
