Arthritis in the hindfoot

Hindfoot: anatomy and function

The hindfoot includes the heel bone (calcaneus) and ankle bone (talus) with the subtalar joint, as well as the joints of the Chopart line: talonavicular and calcaneocuboid joints. These units control eversion and inversion movements, contribute to cushioning and align the foot on a wide variety of surfaces.

• Subtalar joint: crucial for sideways movement and adaptation to bumps.
• Talonavicular joint: “ball joint” of the foot, crucial for rolling and rotational movements.
• Calcaneocuboid joint: stabilizing “key point” on the outside.
• Sinus tarsi: canal-like structure between the talus and calcaneus - often the site of inflammation.
• Surrounding tendons: tibialis posterior, peroneal tendons, Achilles tendon - their condition influences the joint load.

Typical symptoms of hindfoot arthritis

• Pain deep below or in front of the outer ankle, often also on the inside of the back of the foot towards the scaphoid.
• Morning stiffness (>30 minutes) and initial pain, improvement after exercise, increase with overload.
• Swelling/warmth in the sinus tarsi area, talonavicular area or on the side of the Chopart joint.
• Pain during inversion/eversion (sideways movement), difficulty walking on uneven surfaces.
• Exercise intolerance, shortened walking distances, limping.
• Long-term: axial deviations, flattened longitudinal arch (in case of posterior tibial dysfunction).

Causes and forms of inflammatory hindfoot diseases

Hindfoot arthritis is often part of systemic rheumatic diseases. They can occur as a flare or be chronically active. It is not uncommon for mixed patterns with tendon involvement to occur.

• Rheumatoid arthritis (RA): symmetrical, erosive synovitis; Hindfoot and forefoot involvement common.
• Psoriatic arthritis (PsA): asymmetrical, with dactylitis, enthesitis; Hindfoot often affected.
• Spondyloarthritides (e.g. Bechterew's disease, reactive arthritis): emphasize entheses; Hindfoot pain typical.
• Crystal arthropathies: gout (urate) or CPPD; Acutely painful, red, swollen joints possible.
• Post-infectious irritations: after infections; often self-limiting, but relevant for differential diagnosis.
• Juvenile idiopathic arthritis: can affect the hindfoot.

A clear distinction must be made between arthrosis (degenerative, often after an ankle injury) and pure tendon diseases. Both can exist in parallel and worsen the symptoms.

Diagnostics: structured and targeted

The diagnosis is guideline-oriented and - in the case of systemic forms - interdisciplinary with rheumatology. Imaging-guided punctures/infiltrations improve safety and precision.

Conservative treatment: step-by-step plan

The aim is to calm the inflammation, relieve pain, maintain joint function and avoid subsequent damage. The therapy is individual, cause-related and built up gradually.

• Load control: temporary reduction of high load peaks (downhill, cross-country, jumps). Short-term, if necessary, Walker orthosis in acute episodes.
• Shoe/insole supply: stable heel cap, insoles that guide the rear foot, if necessary medial/lateral wedges depending on the axis; Roll-off soles (rockers) to relieve pressure on the talonavicular/chopart.
• Physiotherapy: joint-friendly mobilization, proprioception, strengthening of foot muscles/calves, stretching of the calf muscles; Training on level ground, progression guided by symptoms.
• Physical measures: Cold in the acute phase, later dosed heat for muscular tension.
• Local/topical medication: NSAID gels, short-term oral NSAIDs after benefit-risk assessment; Stomach protection as needed.
• General measures: weight management, quitting smoking, sufficient breaks between exertion, good shoes with volume for periods of swelling.

Conservative options are prioritized. If there is insufficient improvement, we will adapt the measures together and examine additional components.

Systemic drug therapy (in cooperation)

For systemic rheumatic causes, disease-modifying therapy is crucial. This is usually carried out by rheumatology and we coordinate closely.

• DMARDs: e.g. B. Methotrexate, leflunomide, sulfasalazine - to control inflammatory activity.
• Biologics/JAK inhibitors: in case of insufficient DMARD effectiveness and according to rheumatological indication.
• Gout: colchicine in the acute phase, long-term uric acid reduction (e.g. allopurinol) with target value control.
• Accompanying measures: vaccination status, laboratory controls, interaction testing; Treatment goals according to treat-to-target.

Good systemic control reduces hindfoot thrusts and can help avoid interventions.

Targeted injections and orthobiologic options

Intra-articular injections can provide short to moderate relief for local inflammation. The selection is made carefully and imaging-guided.

• Corticosteroid injection: for severe synovitis in the subtalar or talonavicular joint. Benefits and risks (infection, skin/tendon irritation) are discussed in detail.
• Hyaluronic acid: evidence is limited for hindfoot joints; can be discussed in individual cases.
• PRP/autologous preparations: v. a. examined for tendon insertion problems; There is no reliable evidence for hindfoot joints. Use only according to individual indications.

Injections do not replace systemic rheumatism therapy, but can serve as a component in flare management.

When should surgery be considered?

Surgical measures can be considered if conservative and systemic therapies do not provide satisfactory control despite sufficient duration and adherence or if structural damage already exists.

• Arthroscopic/open synovectomy in selected cases with local, treatment-refractory synovitis.
• Correction of misalignments and tendon reconstruction when biomechanics contribute significantly.
• Arthrodesis (stiffening) of the subtalar and/or talonavicular joint for advanced destruction and chronic pain.

The decision is individual and takes into account activity level, axes, bone quality and comorbidities. Our focus is on conservative options; Surgical partners are involved if necessary.

Course, prognosis and goals of treatment

Hindfoot arthritis often occurs in episodes. Early, coordinated therapy can reduce pain, maintain function and limit subsequent damage. Complete freedom from symptoms cannot be achieved in every case; Realistic goals are resilience in everyday life, safe mobility on flat terrain and reduction of flare-ups.

• Regular monitoring of symptoms, function and swelling.
• Adjusting insoles/shoes if axes or swelling change.
• Coordination with rheumatology to optimize systemic therapy.

Self-management in everyday life

• Choice of shoes: firm heel fit, sufficient forefoot volume, roll-off sole; avoid heavily worn shoes.
• Dose the load: interval principle instead of long continuous loads, avoid uneven terrain during bursts.
• Cold applications 10–15 minutes for acute inflammation; Heat for muscle relaxation outside of the acute phase.
• Exercises: gentle mobility and foot muscle exercises according to instructions; Continuity is more important than intensity.
• Diet: friendly to uric acid for gout; sufficient drinking quantity; Alcohol in moderation.
• Smoking cessation and weight management support therapeutic goals.

When you should see a doctor

• Severe pain at rest, significant redness/warmth and rapid increase in swelling.
• Fever, general feeling of illness or new severe pain without an explainable cause.
• Newly occurring misalignment, feeling of instability or hindfoot unable to bear weight.
• Treatment failure despite adequate conservative measures.
• After injury with persistent swelling/pain in the hindfoot.
