Final answer:
The Patellar apprehension test is the most suitable for assessing patellofemoral dysfunction. It identifies discomfort or apprehension as the patella is moved, which is indicative of instability or previous dislocation.
Step-by-step explanation:
The best test to assess patellofemoral dysfunction is the Patellar apprehension test (Option C). This clinical test is designed to evaluate discomfort or potential subluxation of the patella. During the test, the examiner gently pushes the patella laterally while the knee is in extension. A positive test is indicated by the patient expressing apprehension or discomfort, suggesting instability or prior dislocation of the patella. This is in contrast to:
- Lachman test, which is used to assess the integrity of the anterior cruciate ligament (ACL).
- McMurray test, which is used to evaluate meniscal tears.
- Ober's test, which is used to assess tightness of the iliotibial band.
Therefore, to evaluate patellofemoral dysfunction, the Patellar apprehension test is the most appropriate choice from the options provided.
