Haemophilia is a hereditary bleeding disorder caused by deficiency of clotting factor VIII (haemophilia A) or factor IX (haemophilia B), leading to prolonged bleeding after injury. Before modern clotting factor replacement therapy, recurrent joint bleeds (haemarthroses) caused severe haemophilic arthropathy -- progressive joint destruction particularly affecting the knees, ankles, and elbows. Even with modern treatment, haemophilic arthropathy is a significant cause of walking impairment in adults with severe haemophilia.
Haemophilic Arthropathy and Walking
Recurrent joint bleeds deposit iron (haemosiderin) in the synovium, triggering chronic synovial inflammation that destroys cartilage and bone in a pattern similar to inflammatory arthritis. The joints most relevant to walking:
- Ankle: The most commonly affected joint in haemophilia. Progressive ankle arthropathy causes pain, restricted range of motion, and a rigid flat-foot deformity that fundamentally alters gait mechanics. Push-off is lost; heel-to-toe progression is replaced by a flat-footed, shortened stride
- Knee: Knee arthropathy causes pain, swelling, loss of full extension (flexion contracture), and eventually bone-on-bone degeneration
- Hip: Less commonly affected than ankle or knee, but hip arthropathy in haemophilia causes the same antalgic limp as degenerative hip OA
Modern Treatment and Walking Prognosis
Extended half-life recombinant factor replacement (prophylactic) and non-factor therapies (emicizumab for haemophilia A) have substantially reduced spontaneous joint bleed frequency in patients treated from childhood. Younger haemophilia patients on modern prophylaxis have far less arthropathy and better walking function than the previous generation treated with on-demand factor replacement.
For older adults with established haemophilic arthropathy (who were inadequately treated before modern prophylaxis was available), joint damage is established and walking impairment is structural and largely irreversible without arthroplasty.
Walking Cane in Haemophilic Arthropathy
- During acute joint bleeds: the affected joint is swollen, warm, and extremely painful. A walking cane provides offloading while the bleed is treated with factor replacement. The cane reduces the bleeding into the affected joint by reducing mechanical load
- With established arthropathy: long-term cane use for pain management and joint protection, as in other forms of arthritis
- Safe tip choice: the rigid ankle in haemophilic arthropathy means the foot rolls abnormally. A higher-traction tip (Steady Tip) is particularly important for the compromised ankle mechanics
Haemophilia Joint and Cane Use Summary
| Joint | Walking Impact | Cane Role |
|---|---|---|
| Ankle arthropathy | Rigid flat-foot, no push-off | Compensate lost push-off; high-traction tip for rigid ankle gait |
| Knee arthropathy | Pain, flexion contracture, instability | Contralateral cane; load transfer from knee |
| Acute joint bleed (any) | Severe pain, swelling | Cane during bleed episode while factor replacement works |
| Young patient on modern prophylaxis | Reduced arthropathy; near-normal walking | Cane primarily for acute bleed episodes if they occur |
