Area of Science:

  • Orthopedics
  • Sports Medicine
  • Radiology

Background:

  • Anterior knee pain is a frequent complaint among athletes of all ages, with diverse and interconnected causes.
  • Overuse and repetitive minor trauma are key factors in developing lesions in the Hoffa's fat pad, extensor mechanism, and cartilage.
  • The complex anatomy and biomechanics of the patellofemoral joint contribute to unspecific symptoms and diagnostic challenges.

Purpose of the Study:

  • To elucidate the role of imaging techniques in diagnosing the causes of anterior knee pain in athletes.
  • To improve the understanding and management of anterior knee injuries through precise diagnostic evaluation.
  • To highlight how advanced imaging can identify specific pathologies contributing to anterior knee pain.

Main Methods:

  • Review of diagnostic capabilities of various imaging modalities, including Ultrasound (US), Magnetic Resonance (MR), Computed Tomography (CT), and plain films.
  • Emphasis on MR's ability to diagnose superficial tendon injuries and rule out intra-articular derangements.
  • Discussion of CT and MR kinematic studies for evaluating patellofemoral malalignment and maltracking.

Main Results:

  • Imaging techniques like US and MR are effective for diagnosing superficial tendon pathologies and intra-articular issues.
  • MR imaging provides distinct features for identifying prior patellar dislocations.
  • While plain films and CT assess malalignment, advanced CT and MR kinematic studies show promise for understanding maltracking.

Conclusions:

  • Imaging plays a crucial role in precisely identifying the origin of anterior knee pain in athletes.
  • Accurate diagnosis through imaging enhances the understanding and improves the management strategies for knee injuries.
  • Further research into kinematic imaging studies is needed to fully understand patellofemoral maltracking.
