Foot Arthritis
What is Foot Arthritis?
Foot arthritis is degeneration of the foot joints causing pain, swelling and stiffness.
Causes of Foot Arthritis
Foot arthritis is often due to previous injury or long-term deformity.
The foot can also be affected by:
- primary osteoarthritis
- rheumatoid arthritis
- sero-negative inflammatory arthritis
- crystal arthropathy (gout/pseudo-gout)
- haemophilic arthropathy
- Charcot neuroarthropathy.
Foot arthritis is common.
Which Foot Joints are Commonly Affected by Arthritis?
The foot joints most commonly affected by arthritis are the:
- joint at the base of the big toe (1st metatarsophalangeal/MTP)
- midfoot joints (tarsometatarsal and naviculocuneiform)
- hindfoot joints (subtalar, talonavicular and calcaneocuboid).
Please see Foot - Anatomy and Imaging
for more information on where these are.
Symptoms of Foot Arthritis
Symptoms of foot arthritis vary in severity but often get worse over time. They include:
- pain is usually with/after activity. Pain also present at night suggests severe arthritis.
- swelling
- stiffness
- altered foot shape.
Diagnosis of Foot Arthritis
The diagnosis of foot arthritis is made following:
- medical history
- physical examination
- weight-bearing X-rays of the foot.
Other investigations (CT, MRI, etc) may be needed if X-rays do not fully explain the pain or if surgery is planned.
Treatment of Foot Arthritis
Non-surgical treatment
Non-surgical treatment is always important and involves:
- pain relief and occasional anti-inflammatory medications
- activity modification and weight loss
- orthotics (insoles) and braces
- supportive +/- rocker sole shoes.
Cortisone injections do not cure foot arthritis but are used for temporary relief of symptoms prior to holidays and other events. They should not be repeated more than twice unless in unusual situations.
Surgical treatment of foot arthritis
Surgery is only recommended when non-surgical treatment has not controlled pain or deformity, and activity is significantly impaired.
Big toe arthritis
can be treated by "clean-out", 1st MTP fusion
and in selected cases only, the Cartiva 1st MTP joint implant.
Midfoot and hindfoot arthritis
- there are two surgical options:
- "clean-out" - removal of large spurs and inflammation
- fusion - permanently stiffening arthritic joints together with plates, screws and staples.
- There are no joint replacements available for the midfoot and hindfoot joints.
Please see Big Toe (1st MTP) Fusion
and Midfoot and Hindfoot Fusion
under the TREATMENTS menu for more information.
