If you feel or hear a meniscal click while manipulating a stifle in a dog with CrCL disease, what would this indicate?

• A. Injury to lateral meniscus
• B. No meniscal injury
• C. Rupture of Cranial cruciate ligament
• D. Injury to medial meniscus

Answer: (D)

A meniscal tear of the medial meniscus is indicated. In a CrCL-deficient stifle, the medial meniscus is tightly attached and becomes caught between the femur and tibia as the joint moves. This catching often produces a distinct click or slippage when you palpate or manipulate the joint. The lateral meniscus is more mobile and less commonly torn in this scenario, so a audible or felt click most commonly points to injury of the medial meniscus.
