Tibial compression test in the canine stifle: technique
6-year-old Rottweiler, 48 kg, with a 2-week right hindlimb lameness and mild stifle effusion. He is very tense and the cranial drawer cannot be assessed while awake.
Which statement about the tibial compression test is correct?
chevron_right Show answer and explanation
A. It is performed with the stifle in full flexion and the tarsus fully extended
It is the reverse for the tarsus: it must be flexed to tension the gastrocnemius. The stifle is held in slight flexion, at an angle similar to the standing angle.
B. A negative result rules out cranial cruciate ligament rupture
Muscle guarding, chronic periarticular fibrosis or a partial rupture can give a negative test. If suspicion is high, repeat it under sedation.
C. A positive result mainly indicates a meniscal injury
It detects cranial tibial instability due to cruciate insufficiency. A click during the manoeuvre may suggest a meniscal injury, but that is not what defines the test.
D. With the stifle slightly flexed, the tarsus is flexed while the index finger on the tibial tuberosity detects its cranial movement
Correct. Flexing the tarsus tensions the gastrocnemius and mimics weight bearing: if the cruciate is not functional, the tibia moves cranially and you feel it at the tuberosity.
lightbulb Key takeaway
Combine drawer and tibial compression with other signs: effusion, medial thickening ("medial buttress"), pain on hyperextension and muscle atrophy. In large or tense dogs, sedation greatly increases sensitivity, and in partial ruptures the drawer may appear only with the stifle flexed.
