At a Glance: Midfoot Arthritis & Midfoot Fusion
| Condition | Midfoot arthritis — wear of the cartilage in the small joints of the middle of the foot, most commonly the tarsometatarsal (Lisfranc) joints and the naviculocuneiform joint. |
| UK Prevalence | Radiographic midfoot OA affects up to 1 in 8 adults over 50; symptomatic disease is less common but frequently under-diagnosed. |
| Most Common Cause | Previous Lisfranc or midfoot injury (post-traumatic arthritis) — particularly in patients with prior sports injuries; also primary OA and inflammatory arthritis. |
| Diagnosis | Clinical examination, weight-bearing X-rays (AP, lateral and oblique), weight-bearing CT (WBCT), MRI and ultrasound-guided diagnostic injection. |
| Non-Surgical Care | Stiff-soled or rocker-bottom footwear, carbon-fibre footplate, custom orthotics, NSAIDs, ultrasound-guided steroid injections, activity modification, physiotherapy. |
| Surgical Options | Tarsometatarsal (TMT) fusion, naviculocuneiform fusion, combined midfoot fusion, dorsal cheilectomy in selected cases, and 3D-printed patient-specific guides for complex deformity. |
| Outcomes | 85–95% good-to-excellent results reported for midfoot fusion in specialist hands, with reliable pain relief and durable correction. |
