Clarke's Sign (Patellar Grind Test) | Rationale & Interpretation

The video tutorial explains the patellar grind test, also known as Clark's sign, used to assess patellofemoral pain syndrome. The test involves positioning the patient supine, applying force to the patella, and instructing the patient to slowly contract their quadriceps. The test is not pleasant and requires careful monitoring for pain. A positive result may indicate patellofemoral pain syndrome or other conditions like chondromalacia patella. The tutorial emphasizes the importance of slow contraction to avoid discomfort.
