Muscle Strength • Compare bilateral muscles – Strength – Symmetry – Equality – Resistance End Feel Think About It!! • The sensation the examiner feels in the joint as it reaches the end of the range of motion of each passive movement • Bone to bone: This is hard, unyielding – normal would be elbow extension. • Soft–tissue approximation: yielding compression that stops further movement – elbow and knee flexion. End Feel • Tissue stretch: hard – springy type of movement with a slight give – toward the end of range of motion – most common type of normal end feel : knee extension and metacarpophalangeal joint extension. Abnormal End Feel • Muscle spasm: invoked by movement with a sudden dramatic arrest of movement often accompanied by pain - sudden hard – “vibrant twang” • Capsular: Similar to tissue stretch but it does not occur where one would expect – range of motion usually reduced.

  • Examination of the Knee
    Examination of the Knee The Examination For every joint of the lower extremity always begin with the patient in standing IN STANDING INSPECTION 1. Cutaneous Structures: Look for Erythema, scarring, bruising, and swelling in the following areas: a. Peripatellar grooves b. Suprapatellar bursa c. Prepatellar bursa d. Infrapatellar tendon e. Anserine bursa f. Popliteal fossa 2. Muscle & Soft Tissue: a. Quadriceps atrophy b. Hamstring atrophy c. Calf atrophy 3. Bones & Alignment: a. Patella position (Alta, Baha, Winking, Frog eyed), b. Varus or Valgus alignment c. Flexion contracture or Genu recurvatum RANGE OF MOTION - ACTIVE Standing is the best opportunity to assess active range of motion of the knee. 1. Ask the patient to squat into a deep knee bend. Both knees should bend symmetrically. 2. Ask the patient to then stand and extend the knee fully – lock the knee. The knee should straighten to 0 degrees of extension. Some people have increased extension referred to as genu recurvatum. GAIT 1. Look for a short stance phase on the affected limb and an awkward gait if a concomitant leg length discrepancy 2. Look for turning on block 3. Screening 1. Walk on the toes 2. Walk on the heels 3. Squat down – Active Range of Motion testing SPECIAL TESTS 1. Leg Length Discrepancy a. Look at patients back for evidence of a functional scoliosis b. Place your hands on the patients Iliac crests looking for inequality which may mean a leg length discrepancy IN SITTING NEUROLOGIC EXAMINATION 1. Test the reflexes a.

    Review Article Physical Examination of Knee Ligament Injuries Abstract Robert D. Bronstein, MD The knee is one of the most commonly injured joints in the body. Joseph C. Schaffer, MD A thorough history and physical examination of the knee facilitates accurate diagnosis of ligament injury. Several examination techniques for the knee ligaments that were developed before advanced imaging remain as accurate or more accurate than these newer imaging modalities. Proper use of these examination techniques requires an understanding of the anatomy and pathophysiology of knee ligament injuries. Advanced imaging can be used to augment a history and examination when necessary, but should not replace a thorough history and physical examination. he knee joint is one of the most injuries because the current injury may Tcommonly injured joints in the be the sequela of a previous injury. body.
