Age-related changes in the body can significantly contribute to lameness, primarily through conditions like osteoarthritis and general musculoskeletal decline. Osteoarthritis, the most common form of arthritis, affects nearly one-third of people over 65 and involves the deterioration of joint cartilage, leading to pain and reduced mobility. Additionally, age-related bone changes, such as decreased density and increased brittleness, can increase the risk of fractures and slow down the healing process, further contributing to lameness.
How Do Age-Related Changes Cause Lameness?
Several age-related changes in the body can lead to lameness:
- Osteoarthritis: As we age, the articular cartilage that cushions our joints deteriorates, leading to pain and inflammation. This condition, known as osteoarthritis, is a primary cause of lameness in older adults.
- Muscle Weakness: Muscle strength and mass decline with age, reducing support for joints and increasing the risk of instability and injury.
- Bone Density Loss: Bones become less dense and more brittle with age, making them more susceptible to fractures that can cause lameness.
- Reduced Joint Stability: Ligaments and tendons lose elasticity, leading to decreased joint stability and a higher risk of injuries like tears.
- Arteriosclerosis: Hardening of the arteries can reduce blood flow, impairing muscle function and healing, which can exacerbate lameness.
What Is the Role of Osteoarthritis in Causing Lameness?
Osteoarthritis (degenerative joint disease) is a major contributor to lameness in older adults. It is characterized by:
- Cartilage Deterioration: The breakdown of cartilage leads to painful bone-on-bone contact within the joints.
- Joint Pain and Inflammation: Prolonged activity can cause deep, aching pain in the affected joints.
- Crepitus: Crackling noises in the joints during motion are common, indicating cartilage damage.
- Bone Spurs: Enlargement of bony processes (osteophytes) around the joints can further restrict movement and cause pain.
How Does Bone Density Affect Lameness?
Age-related bone density loss, or osteoporosis, significantly increases the risk of fractures, which can lead to lameness. The bone of elderly persons is known to be less dense and more brittle; it tends, therefore, to fracture more easily. It also heals with greater difficulty.

What are the early signs of osteoarthritis?
Early signs of osteoarthritis include joint pain after activity, stiffness, and reduced range of motion. Some individuals may also experience crepitus, a crackling sound, when moving the affected joint.
How can I prevent lameness as I age?
While not all age-related changes are preventable, you can reduce your risk of lameness by maintaining a healthy weight, engaging in regular exercise, and avoiding activities that put excessive stress on your joints. Additionally, a balanced diet and avoiding smoking can promote overall musculoskeletal health.
What treatments are available for age-related lameness?
Treatments for age-related lameness vary depending on the cause and severity. Options include exercise, weight loss, nonsteroidal anti-inflammatory drugs, steroids, and total joint replacement surgery.
Understanding the age-related changes that contribute to lameness can help you take proactive steps to maintain your mobility and quality of life as you age.
