Introduction

  • Wash hands (and don PPE if needed)
  • Introduce yourself (name and role)
  • Confirm patient’s name and DOB
  • Explain what the examination involves
  • Gain consent to continue
  • Ask if patient in any pain before continuing

General Inspection

Clinical Signs

  • Body habitus
  • Scars
  • Obvious swelling
  • Varus or valgus deformity

Objects and Equipment

  • Walking aids
  • Prescriptions

Gait

Walk to the end of the room and turn back

  • Gait cycle and ROM
  • Limping
  • Leg length
  • Turning

Look

Closer inspection of the leg

  • Deformity
  • Wasting
  • Asymmetry
  • Swelling
  • Scars

Feel

Temperature

  • Feel the skin temperature of both legs at the same time with back of hand

Joint lines

  • Palpate for tenderness along the joint line and patella
  • Feel behind the knee for popliteal (Baker’s) cyst

Patella Tap

  • Assess for effusion by performing patella tap

Move

Passive movement

  • Ask the patient to actively extend and flex the joint to maximum and establish RoM and if there is any pain
  • Then ask the patient to relax and passively move the joint with one hand on the patella to feel for crepitus

Fixed flexion deformities

  • Place hand under knee and ask patient to straighten this leg to check for any fixed flexion deformity

Hyperextension

  • Hold the ankle and raise the leg. If hyperextension, the knee will droop

Ligament stability

  • Check for ACL and PCL stability by sitting on foot and pulling forwards and backwards - not trying to illicit pain but looking for physical movement of the joint
  • Test MCL and LCL by trying to move leg in both directions with the other hand acting as a pivot

Special Tests

Meniscus injuries

  • McMurray’s test - half flex and internally rotate the leg to test the lateral meniscus

ACL Injury

  • Lachman’s Test - stabilise the femur with one hand and gently pull the tibia anterior and posteriorly

To Complete the Exam

  • Explain to the patient that the examination is now finished.
