In this article, we’ll focus on midfoot arthritis, a condition that affects the middle part of the foot and can significantly impact mobility and quality of life. We will explore the causes, symptoms, and available treatment options for managing midfoot arthritis.

What is Midfoot Arthritis?
Midfoot arthritis refers to the inflammation and degeneration of the joints in the middle of the foot, specifically the tarsometatarsal (TMT) joints. These joints play a crucial role in maintaining foot stability and facilitating smooth movements during walking and running. When the TMT joints become damaged or deteriorate over time, it leads to midfoot arthritis.

Causes of Midfoot Arthritis:
Several factors can contribute to the development of midfoot arthritis, including:

Age and wear and tear: As we age, the cartilage in our joints naturally wears down, making them more susceptible to arthritis.
Previous injuries: Trauma, such as fractures or dislocations in the foot, can increase the risk of midfoot arthritis.
Abnormal foot structure: Conditions like flat feet or high arches can place excess stress on the midfoot joints, leading to arthritis.
Rheumatoid arthritis: This autoimmune condition can affect multiple joints in the body, including the midfoot.

Symptoms of Midfoot Arthritis:
Recognizing the symptoms of midfoot arthritis is crucial for early diagnosis and appropriate treatment. Some common signs include:

Pain and stiffness in the midfoot, particularly during weight-bearing activities.
Swelling and tenderness in the middle of the foot.
Limited range of motion, making it difficult to perform activities that involve bending or twisting the foot.
The feeling of instability or a “shifting” sensation in the midfoot.
Changes in foot shape, such as the development of fallen arches or hard, bony bumps on the top of the foot

Treatment Options for Midfoot Arthritis:
While midfoot arthritis is a chronic condition, various treatment options are available to manage symptoms and improve overall foot function. These may include:

Medications: Nonsteroidal anti-inflammatory drugs (NSAIDs) can help reduce pain and inflammation associated with midfoot arthritis. In some cases, corticosteroid injections may be administered to alleviate severe symptoms.
Orthotic devices: Custom-made orthotic shoe inserts or braces can provide support and relieve pressure on the midfoot joints, promoting better alignment and reducing discomfort.
Physical therapy: Targeted exercises and stretches prescribed by a podiatrist or physical therapist can strengthen the muscles around the midfoot, improve flexibility, and enhance overall foot function.
Assistive devices: Using assistive devices like canes, walkers, or shoe modifications can help offload weight from the affected midfoot joints, reducing pain and improving mobility.
Footwear modifications: Wearing appropriate shoes with arch support, and a roomy toe box can help alleviate symptoms and provide comfort for those with midfoot arthritis.
Surgical interventions: In severe cases where conservative measures fail to provide relief, surgical options such as painful spur removal or midfoot arthrodesis (fusion) may be considered to alleviate pain and restore foot function.
