Taming the Musculoskeletal Exam: İSí, se puede! Ronald H. Labuguen, MD UCSF Department of Family and Community Medicine NP/PA/CNM Professional Practice Conference San Francisco Department of Public Health October 17, 2013 Objectives 1. To learn principles of examining patients with common joint problems 2. To learn common clinical scenarios for common musculoskeletal problems 3. To learn how to approach diagnosis and treatment of common musculoskeletal problems in primary care and urgent care settings Objectives 4. To review elements of the physical examination of the shoulder, elbow, hand/wrist, hip, knee, ankle, and foot 5.

Copyright © 2007 American Academy of Family Physicians Patellofemoral Pain • Overuse/ overloading • Diffuse, aching anterior knee pain • Sometimes caused by patellar malalignment Patellofemoral Pain • Feels like knee “catches” or might “give way” • Worst when – Running – Going up/down stairs – Kneeling, squatting – Getting up after sitting for a while Patellofemoral Pain • Weight bearing stance and gait: – Patellae point to each other – Knock-knees – Foot pronation Patellofemoral Pain • Excessive femoral anteversion (hip internal rotation > external rotation by 30°+) • J sign (patella moves laterally >1 cm near full extension) • Tight hamstrings, quadriceps • Patellar grind test • Patellar apprehension test Lateral patellar tracking ("J" sign). As the knee is extended from 90 degrees flexion (A) to full extension (B), the patella demonstrates an abnormal path, deviating laterally at full extension. Patellar mobility testing. Depicted is medial glide testing performed on the right knee. The patella is grasped in the resting position (A), then translated medially (B). The extent of displacement is described in relation to the width of the patella and measured in quadrants (C). Displacement of less than one quadrant medially indicates tightness of the lateral structures. Displacement of more than three quadrants is considered hypermobile. Patellar tilt test. This test assesses for tightness of the lateral structures. The knee is extended and the patella is grasped between the thumb and forefinger. The medial aspect of the patella is then compressed posteriorly while the lateral aspect is elevated. If the lateral aspect of the patella is fixed and cannot be raised to at least the horizontal position (0 degrees), the test is positive and indicates tight lateral structures. This also can be seen in patients with patellofemoral osteoarthritis. Patellar grind (or inhibition) test. While the patient is in the supine position with the knee extended, the examiner displaces the patella inferiorly into the trochlear groove (pictured). The patient is then asked to contract the quadriceps while the examiner continues to palpate the patella and provides gentle resistance to superior movement of the patella. The test is positive if pain is produced, although comparison to the contralateral knee is needed to interpret the result.

The patient lies down with the unaffected side down and the unaffected hip and knee at a 90degree angle. If the iliotibial band is tight, the patient will have difficulty adducting the leg beyond the midline and may experience pain at the lateral knee (arrows).
