Knee HOPS


History

HISTORY

  • We estimate that the proper diagnosis can be achieved in 80 - 85% of cases from a properly performed history alone. (Univeristy of Minnesota Sports Medicine)

  • How

    • What sport

    • Contact v. non-contact

      • Non-contact think ACL

      • Valgus force think MCL

      • Varus force think LCL

      • Rotational force think meniscus or ACL


Knee hops

  • Did it feel like it gave out

  • Did you hear or feel a “pop”

  • Chronic v. acute onset

  • Functional limitations

    • Locks think meniscus

    • Pain with deep knee bends or stairs think meniscus


Observation

OBSERVATION

  • It is important to observe the symptomatic knee for any deformities, abnormal alignment, surgical scars, lacerations, discoloration and swelling.

  • Observe the gait

    • Unable to extend knee fully when walking think ACL

    • Knee locked when walking think meniscus


Knee hops

  • Swelling

    • Intraarticular: swelling inside the joint (capsule) will result in the loss of the normal contour of the extensor mechanism. May see a “fluid wave” think meniscus, ACL or PCL


Knee hops

  • Extraarticular: swelling oustide of the joint. Localized swelling and a traumatic etiology can indicate either a localized hematoma or a localized joint injury.

    • Medial aspect of knee think MCL

    • Lateral aspect of knee think LCL

    • Anterior aspect think bursitis, tendonitis

    • Tibial tuberosity think Osgood-Schlatters

    • Posterior aspect think Baker’s


Palpation

PALPATION

  • Bony

    • Head of fibula – think LCL

    • Tibial tuberosity –think Osgood Schatter’s

    • Joint line/tibial plateau- think meniscus

    • Patella – inferior pole think Lars-Johansen


Knee hops

  • Muscular

    • Quadriceps and quadriceps tendon

    • Hamstrings and tendons

    • Origin of gastrocnemius

  • Ligaments

    • MCL on medial side

    • LCL on lateral side

    • Cannot palpate ACL or PCL


Special tests

Special Tests

  • ROM– active,passive and resistive knee flexion and extension

  • Patellar grind test-- chondromalaysia
