Recurrent hemarthroses → synovial hypertrophy → cartilage damage and arthropathy (ankle, knee, elbow). Evaluation: bleeding history, factor levels/inhibitors, US/MRI for synovitis and osteochondral damage. Acute bleed management: RICE + factor replacement to target levels (VIII or IX). Chronic synovitis: radiosynovectomy/arthroscopic synovectomy; advanced arthropathy—osteotomy, arthrodesis, arthroplasty. Always coordinate with hematology for perioperative factor protocol ± antifibrinolytics.

Haemophilic arthropathy is a chronic joint disease that develops in patients with haemophilia due to recurrent episodes of bleeding into joints, known as hemarthrosis. Repeated intra-articular bleeding leads to progressive joint damage, synovial hypertrophy, cartilage destruction and eventually secondary osteoarthritis.
Haemophilia is an inherited bleeding disorder caused by deficiency of clotting factors. Haemophilia A results from deficiency of factor VIII, while haemophilia B results from deficiency of factor IX. Because clotting is impaired, even minor trauma may lead to bleeding within joints and soft tissues.
Large synovial joints are most commonly affected, particularly the knee, ankle and elbow. Early recognition and appropriate treatment are important to prevent permanent joint damage and disability.
Recurrent bleeding into the joint cavity initiates an inflammatory cascade within the synovium. Blood breakdown products stimulate synovial hypertrophy and proliferation, resulting in chronic synovitis.
The hypertrophied synovium becomes highly vascular and fragile, making it more susceptible to further bleeding episodes. This cycle of bleeding and inflammation gradually damages the articular cartilage.
Over time the joint becomes stiff, painful and deformed due to chronic structural damage.
Certain joints are particularly prone to recurrent bleeding in haemophilia because they are exposed to frequent mechanical stress during daily activities.
| Joint | Frequency of Involvement |
|---|---|
| Knee | Most commonly affected joint |
| Ankle | Second most common |
| Elbow | Common in children and adolescents |
| Hip and shoulder | Less frequently involved |
These joints often become known as target joints due to repeated bleeding episodes.
Patients with haemophilic arthropathy often present with a history of recurrent joint bleeding. The symptoms vary depending on the stage of the disease.
During acute bleeding episodes the joint becomes warm, swollen and painful. Chronic disease leads to progressive stiffness and deformity.
Haemophilic joint disease progresses through several stages depending on the severity and frequency of bleeding episodes.
| Stage | Features |
|---|---|
| Acute hemarthrosis | Painful swollen joint due to bleeding |
| Chronic synovitis | Persistent synovial hypertrophy |
| Cartilage degeneration | Progressive joint damage |
| End stage arthropathy | Severe degenerative arthritis |
Imaging studies are important for evaluating the severity of joint damage in haemophilic arthropathy.
| Imaging Modality | Findings |
|---|---|
| Plain radiograph | Joint space narrowing and osteophytes |
| MRI | Synovial hypertrophy and cartilage damage |
| Ultrasound | Detection of joint effusion and synovitis |
MRI is particularly useful in detecting early synovial changes before significant joint damage occurs.
Management of haemophilic arthropathy focuses on preventing bleeding episodes, controlling synovitis and preserving joint function.
Early prophylactic factor replacement therapy has significantly reduced the incidence of severe joint disease in haemophilia patients.
Acute bleeding episodes should be treated promptly to prevent long term joint damage.
Early treatment often leads to rapid symptom relief and prevents further joint damage.
Surgical treatment may be required in patients with advanced haemophilic arthropathy who develop severe joint destruction.
Total knee replacement is one of the most commonly performed procedures in patients with advanced haemophilic arthropathy.
Preventive strategies play a crucial role in reducing the burden of haemophilic arthropathy.
Early preventive care significantly improves long term functional outcomes in patients with haemophilia.
