Dogs may need to be anesthetized for a thorough evaluation of the stifle. Injuries to the meniscus are associated with injuries to the cruciates. If a cruciate injury goes untreated, secondary damage to the meniscus occurs in the weeks and months that follow. The end result is a degenerative arthritis and permanent lameness. Anatomy, Structure, and Function 118 The stifle joint is classified as a complex condylar synovial joint owing to the separation of its articular surfaces by intra-articular fibrocartilages—the menisci.

Canine medial and lateral femoral condyles are equally prominent, but the articular surface of the medial femoral condyle projects more cranially than that of the lateral femoral condyle. Dogs are quadruped with digitigrade posture. After hard work, these muscles may become tight and sore. Dogs have disconnected shoulder bones (lacking the collar bone of the human skeleton) that allow a greater stride length for running and leaping. For Practitioners. Alteration in any one of these components often leads to dysfunction as well … Each of these types of tissue serves a different purpose in the body of a dog and is under the control of either the voluntary or involuntary system.
