Foot Arthritis

  • Ankle Joint The connection between the shin bone (tibia) and the ankle bone (talus).

  • Midfoot Joints: The three joints of the foot involving the heel bone (calcaneus), inner mid-foot bone (navicular), and outer mid-foot bone (cuboid).

  • Great Toe Joint: The joint of the great toe (hallux) and the foot bone (first metatarsal).

Arthritic Joints

  • Osteoarthritis: The most common form, characterised by the gradual wearing away of cartilage, leading to pain, stiffness, and bone-on-bone contact.

  • Rheumatoid Arthritis: An autoimmune condition where the body’s immune system attacks healthy joints, often affecting the same joints on both sides of the body simultaneously.

  • Post-traumatic Arthritis: Develops after an injury such as a fracture or dislocation, potentially arising years after the initial trauma.

  • Gout/Pseudogout Arthritis: Caused by the build-up of uric acid crystals in the joints, leading to pain and inflammation.

Types of Arthritis

  • Age: Natural wear and tear of cartilage as you age.

  • Genetics: Family history of arthritis or joint issues.

  • Previous Injuries: Fractures, dislocations, or severe sprains can lead to post-traumatic arthritis.

  • Obesity: Increased weight puts extra stress on foot joints.

  • Repetitive Stress:Overuse from activities like running or standing for long periods.

  • Autoimmune Conditions: Diseases like rheumatoid arthritis where the immune system attacks healthy joints.

  • Gout: Accumulation of uric acid crystals in the joints.

  • Infections: Joint infections that can cause or exacerbate arthritis.

Causes of Arthritis

The Symptoms

  • Tenderness and pain when touching or moving the joint.

  • Difficulty moving, walking, or bearing weight.

  • Joint stiffness, warmth, and swelling.

  • Increased pain and swelling after periods of rest, such as after sitting or sleeping.

The Diagnosis

  • Medical History: The doctor will inquire about symptoms, previous injuries, family medical history, and the impact on your lifestyle.

  • Physical Examination: The affected area is examined for swelling, pain, and range of motion.

  • Diagnostic Testing: May include X-rays, Ultrasound (US), CT scans, or MRI to determine the extent and specific cause of the arthritis.

Stages of Foot Arthritis:

  • Early Stages: Sharp and intense pain in the affected joints.

  • Later Stages: The pain evolves into a dull ache, spreading across a larger area of the joint.

Foot Arthritis Treatments

Surgical

  • Arthroscopic Surgery: Minimally invasive surgery to clean the joint of foreign tissue or bone spurs.

  • Arthroplasty (Joint Replacement): Replacing the damaged joint with an artificial implant, usually for severe cases.

  • Arthrodesis (Fusion): Permanently stiffening the joint using plates and screws, often for joints already with limited motion.

Non-Surgical

  • Rest: Limiting activity to reduce symptoms.

  • Pain Medication: Over-the-counter options like Paracetamol, Ibuprofen, or NSAIDs.

  • Exercise Training: Physical therapy to strengthen the area and reduce pain.

  • Shoewear Modification and Orthotics: Custom or accommodative footwear and shoe inserts to support the foot.

  • Injection Therapies: Corticosteroids to reduce inflammation.
