A stiff, painful ankle years after a fracture or a run of sprains. Dorsiflexion goes first, so every step is taken on a stiff ankle - the knee and hip compensate, the calf shortens, and the position sense that would protect the joint went with the sprains years ago.
How common: About 3-6% of adults; unlike the hip and knee, 70-80% of it follows an old fracture or repeated sprains, so it arrives about 14 years earlier in life
What it is
Unlike the hip and knee, ankle arthritis is usually post-traumatic rather than age-related. The great majority of cases follow a fracture or repeated sprains, and the joint wears unevenly because its mechanics were altered by the original injury.
Dorsiflexion is the first range lost, which matters more than it sounds. Almost every step, stair and squat needs the shin to travel forward over the foot; without it the compensations move up the chain to the knee, hip and back, and the calf shortens around the restricted position.
What it feels like
- Stiffness and aching in the ankle, worse in the morning and after rest
- Pain at the front of the ankle at the limit of bending forward
- Difficulty on slopes, stairs and uneven ground
- Swelling after activity
- A history of a fracture or of multiple sprains, often decades earlier
What causes it
Most people have more than one of these at once, and they feed each other. Read the
list looking for the two or three that sound like your week rather than for the one
true answer — the ones that describe you are the ones worth acting on.
- A previous ankle fracture
- Any fracture involving the joint surface alters the way load is distributed. Even a well-treated fracture leaves the joint mechanically different, and arthritis follows years or decades later.
- Repeated sprains
- Chronic instability means repeated abnormal loading and small episodes of joint surface damage. This is why chronic ankle instability is a direct route to ankle arthritis.
- Lost dorsiflexion
- Once the joint stiffens at the front, every step is taken through a smaller range and load concentrates on a smaller area. It is both a consequence and a driver.
- A shortened calf
- The calf adapts to the restricted range and then maintains it. This is a modifiable part of the problem that is often overlooked in favour of the joint itself.
- Compensation up the chain
- With the ankle unable to supply movement, the knee, hip and low back do more. This produces secondary problems that are frequently what actually brings someone in.
- Lost proprioception
- The position sense that was damaged by the original sprains never recovered, so the joint is less well protected during every step on uneven ground.
- Weak calf and foot muscles
- Years of a painful ankle produce muscle loss around it. Less muscle means the joint absorbs more of every step directly.
- Body weight
- Load through the ankle in walking is several times body weight. It is a genuine mechanical factor in symptom severity.
- Inflammatory arthritis
- Rheumatoid and psoriatic arthritis affect the ankle and are a different disease with different treatment. Symmetrical involvement, morning stiffness over an hour and other joints involved are the flags.
Who tends to get it
- Anyone with a previous ankle fracture, which is the commonest route by far
- People with chronic ankle instability or repeated sprains
- Former athletes in court and field sports
- Anyone with an inflammatory arthritis
- People carrying extra weight, which increases the load through a compromised joint
What makes it worse, and what settles it
Makes it worse
- Long periods of standing or walking on hard surfaces
- High-impact activity through a stiff, poorly controlled joint
- Complete rest, which stiffens it further and weakens the calf
- Ignoring the calf, which maintains the restriction
- Uneven ground, where the lost position sense is most exposed
Settles it
- Ankle mobility work - knee-to-wall mobilisation for the joint glide, not just calf stretching
- Calf strengthening and stretching, both of which are needed
- Balance work, which addresses the proprioceptive loss the sprains left behind
- Low-impact activity - cycling, swimming, water walking - which maintains the joint without the impact
- Massage of the calf and foot for symptom relief and to help the range work
What actually helps
The short version: A joint that was broken or repeatedly sprained wears unevenly. Dorsiflexion is lost first, so every step is taken on a stiff ankle and the knee and hip compensate, the calf shortens, and the position sense that should protect the joint went years ago with the sprains
Strength work: Legs: Calves: Gastrocnemius and Soleus; Legs: Calves: Peroneals (Fibularis); Legs: Calves: Tibialis Posterior and Tibialis Anterior; Feet, Toes, Ankles: Intrinsic Foot Muscles; Glutes: Med; Legs: Quads - strength around the joint reduces the load through it; Pool Exercises and cycling for cardio that does not pound it
Stretching: Legs: Calves; Legs: Calves: Gastrocnemius and Soleus; Legs: Calves: Achilles Tendon; Feet, Toes, Ankles - ankle circles and gentle dorsiflexion rocking, daily
Massage: Legs: Calves; Feet, Toes, Ankles; Legs: Calves: Peroneals (Fibularis)
Also worth doing: Balance work every day; a stiff-soled shoe with a rocker bottom, which does the ankle's job for it; keep weight down; an ankle brace for uneven ground; a foot and ankle specialist when pain limits walking distance despite all of this - there are good surgical options
What the evidence says: Education and exercise are the recommended first step for osteoarthritis at every joint, though ankle-specific trials are few and mostly small; conservative treatment is effective at every stage and should be tried first. The evidence borrowed from chronic ankle instability - strength, balance and dorsiflexion range - is the practical basis.

Get it checked if…
A hot, red, swollen ankle with fever - infection or gout, urgent; sudden severe pain after a twist - a new fracture; numbness or a cold foot
And whatever the body part: chest pain or unusual breathlessness on
exertion; a fever alongside the pain; unexplained weight loss; pain that is constant and
unrelated to how you move; new numbness, weakness or loss of bladder or bowel control; or
one calf that is swollen, warm and painful. Any of those, stop and get assessed.
How it usually goes
Mobility and strength work improve function and pain over eight to twelve weeks, and restoring even a few degrees of dorsiflexion changes stairs, slopes and walking noticeably. It does not reverse the joint change and progression is likely over years, but the compensations up the chain are largely preventable. For end-stage ankle arthritis, fusion and replacement are both effective options - and people who go into either stronger recover better, which makes the work worthwhile regardless.

Others the same routine covers
These share the Ankle Stability & Sprain Recovery routine, so the work is the same. If one of them also
sounds like you, that is a reason to expect more from it, not less.
This is general information, not a diagnosis, and it cannot examine you.
If it matches you, use it to ask better questions of a clinician rather than to replace one.
