Summary
Ankle joint replacement offers a biomechanically superior alternative to fusion for patients with haemophilia, improving mobility and reducing pain. Specialized interdisciplinary centers are crucial for minimizing complications in haemophilic arthropathy treatment.
Area of Science:
- Orthopedic Surgery
- Hematology
- Biomechanics
Background:
- Secondary arthrosis of the talocalcaneal joint is a common complication of haemophilic arthropathy, stemming from recurrent bleeds and joint misalignment.
- This condition can lead to subtalar joint ankylosis and foot drop (talipes equinus), even in young patients.
Observation:
- A 52-year-old male with severe haemophilia A underwent open joint cleansing for ankle pain and talonavicular arthrosis.
- While improving mobility, this exacerbated upper ankle joint arthrosis and pain, leading to consideration for joint replacement.
Findings:
- A cement-free upper ankle joint endoprosthesis was implanted in the patient.
- Post-surgery, the patient experienced pain-free mobility and good foot function without assistive devices within three months.
Implications:
- Subtalar joint endoprosthesis implantation is a viable alternative to arthrodesis for haemophilic patients with severe ankle arthropathy.
- Optimal management requires treatment at specialized interdisciplinary centers with experienced surgical and haemostaseology teams to reduce complication rates.

01:10Ankle Joint
The ankle is formed by the talocrural joint (crural = leg). It consists of the articulations between the talus bone of the foot and the distal ends of the tibia and fibula of the leg. The superior aspect of the talus bone is square-shaped and has three areas of articulation. The top of the talus articulates with the inferior tibia. This is the portion of the ankle joint that carries the body weight between the leg and foot. The sides of the talus are firmly held in position by the articulations...
01:25Hemodialysis I: Introduction
Hemodialysis (HD) is a medical treatment that artificially removes waste products, excess fluids, and toxins from the blood when the kidneys are no longer able to perform these functions effectively. In this process, blood is filtered through a semipermeable membrane, allowing for the selective removal of waste while preserving necessary components like blood cells and proteins. Hemodialysis is typically performed in patients with end-stage renal disease (ESRD) or severe kidney...
