Summary
A thorough physical exam of the knee and lower leg is key to diagnosing subtle extensor mechanism disorders. This review covers standing, sitting, and supine patient assessments and imaging techniques for the patellofemoral joint.
Area of Science:
- Orthopedic Surgery
- Sports Medicine
- Biomechanics
Background:
- Extensor mechanism disorders can be subtle and challenging to diagnose.
- A comprehensive evaluation is necessary for accurate diagnosis.
Purpose of the Study:
- To present physical examination techniques for patellofemoral joint disorders.
- To review radiographic methods for evaluating the patellofemoral joint.
Main Methods:
- Detailed description of standing, sitting, and supine physical examinations.
- Review of various radiographic imaging modalities for the patellofemoral joint.
Main Results:
- Physical examination of the entire lower extremity is crucial.
- Specific examination positions aid in detecting subtle disorders.
- Radiographic techniques provide valuable diagnostic information.
Conclusions:
- A systematic physical examination combined with appropriate radiographic imaging is essential for diagnosing extensor mechanism disorders.
- Understanding these diagnostic approaches improves patient care for patellofemoral pain.
