Diseased Joints

Components of the diseased joint cycle1

Degenerative joint disease (DJD) starts with an inflamed joint, which results in mild pain, swelling, and disruption to the balanced 'wear and repair' cycle.

Inflamed synovial membrane allows unwanted cells to pass into the synovial (joint) fluid. These cells release destructive enzymes break down the lubricant and barrier function.

Destructive enzymes attack the synovial fluid and cartilage causing damage.

Eroded articular cartilage
Healthy cartilage is critical to the performance of the joint. Eroded cartilage loses its ability to evenly distribute the forces of movement into the subchondral bone, allowing injury to occur. It contains no sensory nerves or blood vessels, so it has a limited ability to repair itself.

Damaged subchondral bone
Subchondral bone does contain sensory nerves and blood vessels. When damage occurs, it can be an additional source of joint pain.

Signs of degenerative joint disease.2

Swelling due to excess joint fluid and inflammation

Lameness which can preclude comfort and athleticism

Decreased range of motion

Stiffness when emerging from the stall or starting work

Deformation caused by bony changes

Crepitus—the popping, grinding, and crackling sound and sensation in an affected joint.


Start treatment early.

The onset and progression of degenerative joint disease results in the loss of cartilage components, so early intervention is important. Once a diagnosis is made, develop a treatment plan focused on inhibiting the destructive processes of DJD in the beginning stages - before mobility is compromised. Adequan® I.M. is proven to work in multiple ways to maintain joint function.3,4
