Arthroscopic ankle surgery in people with haemophilia.

INTRODUCTION: People with haemophilia (PWH) not administered primary haematological prophylaxis since childhood, that is, those treated haematologically on demand or not treated at all, often experience the degeneration of the ankles, leading to pain and functional impairment.

AIM: To analyse the outcomes and complications of arthroscopic ankle surgery performed on PWH.

METHODS: For this narrative review of the literature, a search was conducted in PubMed on 2, December 2023, using the keywords "haemophilia", "ankle" and "arthroscopy". Of the 29 articles identified, 15 specifically related to ankle arthroscopy in PWH were selected (inclusion criterion). The remaining articles did not meet this requirement (exclusion criterion) and were therefore eliminated.

RESULTS: Arthroscopic procedures (arthroscopic synovectomy, debridement and arthrodesis of the ankle) are increasingly used in the surgical treatment of haemophilic ankle arthropathy. Although arthroscopic ankle surgery offers good outcomes in patients with haemophilia, the procedure is not free of complications, which range from 7.9% for arthroscopic ankle debridement to 13.1% in arthroscopic ankle synovectomy and 17.8% in arthroscopic ankle arthrodesis, respectively. The non-union rate of arthroscopic ankle arthrodesis is 7.1% (2/28).

CONCLUSION: Although arthroscopic interventions in the haemophilic ankle (synovectomy, debridement, arthrodesis) offer good functional outcomes, they are associated with a non-negligible rate of complications. Arthroscopic ankle surgery in PWH is major surgery and should be treated as such.
