What is Lower Limb Arthritis?
Arthritis is a term for inflammation of the joints. The two most common types that affect the lower limbs are osteoarthritis and rheumatoid arthritis.
- Osteoarthritis (OA): Often referred to as “wear and tear” (but more recently being referred to as “wear and repair”), osteoarthritis occurs when the cartilage that cushions the ends of your bones gradually wears away. This leads to the bones rubbing against each other and/or the development of extra bone around the joint (known as osteophytes), causing pain, swelling, and reduced joint movement. Osteoarthritis frequently affects the hips, knees, ankles, mid-foot, and toe joints..
- Rheumatoid Arthritis (RA): Rheumatoid arthritis is an autoimmune disorder in which the immune system mistakenly attacks the joints, leading to inflammation. This condition can cause significant pain and swelling, particularly in the small joints of the feet and toes, eventually leading to joint deformity if left untreated.
The information below relates more to osteoarthritis, but some of the information is applicable to rheumatoid arthritis.
Symptoms of Lower Limb Arthritis
The symptoms of arthritis in the lower limbs can vary depending on the severity and the specific joints affected. Common symptoms include:
- Pain: Persistent joint pain is often the most noticeable symptom of arthritis. This pain may worsen with activity and improve with rest.
- Stiffness: Joints affected by arthritis can feel stiff, especially in the morning or after periods of inactivity.
- Swelling: Inflammation can cause the affected joints to swell, making them appear larger and feel tender to the touch.
- Reduced Range of Motion: Arthritis can limit the movement of the affected joints, making everyday tasks such as walking or climbing stairs difficult.
Joint Deformity: In more severe cases, the affected joints may become misshapen due to chronic inflammation and damage to the cartilage and bone.
Treatment Options for Lower Limb Arthritis
Although there is no cure for arthritis, various treatment options are available to help manage your symptoms and improve your quality of life. At Health First Foot and Gait Clinic, we tailor treatment plans to your individual needs, which may include a combination of conservative therapies, lifestyle modifications, and, in some cases, surgical interventions.
Causes and Risk Factors
The exact cause of arthritis is not always known, but several factors can increase your risk of developing the condition, particularly in the lower limbs:
- Age: As we age, the risk of developing arthritis increases, with joints experiencing wear and tear over time.
- Genetics: If there’s a family history of arthritis, your chances of developing the condition may be higher, particularly with rheumatoid arthritis.
- Previous Injury: Injuries such as fractures or dislocations can lead to arthritis later in life.
- Obesity: Carrying excess weight places additional stress on the weight-bearing joints in your lower limbs, increasing the risk of osteoarthritis.
Repetitive Strain: Jobs or activities that require repetitive motions or heavy lifting can contribute to the development of arthritis in the lower limbs.
Diagnosing Lower Limb Arthritis
A thorough assessment by our podiatrists is essential to accurately diagnose arthritis in the feet & ankles. During your consultation, we will review your medical history, conduct a physical examination, and may recommend imaging tests such as X-rays or MRIs to assess the extent of joint damage.
- Physical Examination: Our podiatrists will assess the affected joints for signs of swelling, tenderness, and reduced range of motion. We will also evaluate your gait and posture to identify any compensatory movements that may be contributing to your symptoms.
Imaging Tests: X-rays help us visualise the extent of cartilage loss and bone damage, while MRIs provide a more detailed view of the soft tissues, including cartilage and ligaments.
