Stifle: cranial drawer test

Contributor(s): Neil Burton

Introduction

  • To assess stifle joint instability by attempting to subluxate the tibia cranially with respect to the femur.

Uses

Disadvantages

  • Normal joint laxity in the young dog may be confused with a pathologically unstable joint.
  • Inward rotation of the tibia may be misinterpreted as a positive cranial draw movement - a normal finding in a healthy joint; inward rotation is increased in a cruciate deficient joint.
  • Chronically affected joints, or joints with partial rupture of cranial cruciate ligament, will have much less draw/no draw movement.
  • Ruptures of caudolateral band will remain undetected (craniomedial band stabilizes joint).
  • Acute ruptures producing severe joint effusion will have reduced draw motion.
