Knee Plical Pathology and Impingement Syndromes

Area of Science:

• Orthopedics
• Radiology
• Sports Medicine

Background:

• Impingement syndromes of the knee arise from anatomical variations or biomechanical issues.
• Painful symptoms in patients are often linked to specific imaging findings.
• Understanding these conditions is crucial for effective patient management.

Purpose of the Study:

• To discuss MR imaging findings in knee impingement syndromes.
• To highlight the role of imaging in explaining patient symptoms and guiding management.
• To review common knee impingement conditions and their imaging features.

Main Methods:

• Review of MR imaging findings in various knee impingement syndromes.
• Discussion of relevant embryology and anatomical variations of synovial plicae.
• Presentation of common knee impingement conditions, including iliotibial band fraction syndrome, Hoffa fat pad impingement, and suprapatellar/quadriceps fat pad impingement.

Main Results:

• MR imaging can reveal characteristic findings associated with synovial plica syndrome and other knee impingements.
• Anatomical variations of synovial plicae can predispose individuals to symptomatic impingement.
• Common impingement syndromes like IT band syndrome and fat pad impingements have distinct MR imaging appearances.

Conclusions:

• MR imaging is essential for diagnosing knee impingement syndromes by correlating findings with patient symptoms.
• Knowledge of embryology and anatomy aids in identifying predisposing factors for impingement.
• Comprehensive review of common impingement syndromes provides a basis for accurate diagnosis and management.
