Reconstructive techniques for revision and limb salvage surgery in persons with haemophilia.

Haemophilia is an inherited haemorrhagic disease characterized by the lack of coagulative factors associated nowadays mostly to musculoskeletal complications, particularly severe secondary arthritis in specific joints. Recurrent traumatic or spontaneous joint bleeding, induce severe arthropathy at a young age that can be treated only by joint replacement. Total knee or hip arthroplasty in young subjects may fail earlier due to wear or infections and in the haemophilic population, this means bone loss, pseudo tumours and the need of revision or even limb salvage surgery. Modern modular implants and the use of bone graft enriched by tissue engineering techniques such as a concentration of autologous mesenchymal cells or PRP may be helpful to compensate all bone loss and anatomic alterations due to failures of orthopaedic implants. The authors present their experience with this type of surgery and their biological approach to these challenging cases.
