[Knee pain: choosing the right imaging]

Area of Science:

• Orthopedics and Sports Medicine
• Diagnostic Imaging
• Primary Care Medicine

Context:

• Gonalgia, or knee pain, is a common reason for primary care consultations.
• Effective diagnosis requires a systematic clinical approach before advanced imaging.
• Appropriate utilization of diagnostic tools is crucial for efficient patient management.

Purpose:

• To outline the diagnostic pathway for gonalgia in primary care settings.
• To emphasize the importance of clinical assessment in knee pain diagnosis.
• To guide the selection of appropriate imaging modalities for knee pathologies.

Summary:

• The diagnostic process for gonalgia primarily involves a thorough clinical evaluation, including detailed medical history and physical examination.
• Initial imaging, such as knee joint X-rays, is common but not always necessary, particularly after minor trauma.
• Advanced imaging like MRI and CT scans are reserved for specific diagnostic questions, while echography is typically used for extra-articular conditions and joint aspiration guidance.

Impact:

• Facilitates more accurate and timely diagnosis of knee pain conditions.
• Optimizes the use of healthcare resources by guiding appropriate imaging test selection.
• Improves patient outcomes through evidence-based diagnostic strategies in primary care.
