Ankle surgery in haemophilia with special emphasis on arthroscopic debridement

Various conservative options are available to treat ankle problems in haemophilia, which achieve a high rate of satisfactory results in the majority of cases. They are usually employed in combination and include the use of patellar tendon bearing (PTB) orthoses and radiosynoviorthesis. The effect of the PTB orthoses is that it allows the patient to walk without weight bearing of the ankle. Radiosynoviorthesis can be performed in cases of haemophilic arthropathy of the ankle, provided there is at least a minimal degree of synovitis within the joint, with a 75% of satisfactory results. If the conservative options fail, surgical intervention can be indicated. Alternatives to total ankle arthroplasty or arthrodesis include arthroscopic debridement, removal of osteophytes of the anterior aspect of the distal tibia and peri-articular osteotomies to correct angular, rotational or translational malalignment. Ankle arthrodesis is the standard technique for end-stage ankle arthropathy. Arthroscopic debridement of the ankle with haemophilic arthropathy can offer temporary relief; however, it is important to stress to patients that the degree of improvement is limited. The complication rate in ankle arthroscopy is high compared with other joints, which is especially true for neurological complications and postoperative infections. Orthopaedic procedures are not very frequent in the haemophilic ankle, because the majority of problems can be solved satisfactorily by conservative means (radiosynoviorthesis and PTB orthosis).
