## Overview Meniscal injury is tearing of the medial or lateral meniscus in the stifle. The medial meniscus is more commonly affected. It causes moderate to severe hind-limb lameness, stifle effusion, and pain on flexion. Clicking may be heard. Diagnosis relies on ultrasound, and magnetic resonance imaging provides additional detail. ## Causes Trauma or degenerative tearing, analogous to human knee meniscal injuries. ## Diagnosis Lameness examination, intra-articular analgesia, ultrasound, and sometimes magnetic resonance imaging or arthroscopy. ## Treatment Rest and anti-inflammatories for mild lesions. Arthroscopic debridement for tears that do not respond. Prognosis depends on the extent of the tear and concurrent osteoarthritis. ## Recovery and Prognosis Guarded to fair. Severe tears extending under the femoral condyle have a poorer outlook. ## Prevention None specific.
moderate to severe hind-limb lameness; stifle effusion; pain on flexion; possible clicking; medial meniscus more often affected
