Radiosynovectomy in haemophilic synovitis and arthropathy of the knee: A scoping review

Abstract

IntroductionRadiosynovectomy is an established treatment for chronic synovitis in patients with haemophilia. Although its role in rheumatological diseases has diminished, it remains an accepted therapy for haemophilic synovitis.AimThe aim of this scoping review was to map and summarise the evidence surrounding radiosynovectomy in haemophilic knees, identify gaps in the literature and inform future research.ResultsForty‐three manuscripts and abstracts were identified for this review. Evidence was limited to observational studies and Yttrium‐90 was the most studied licensed radioisotope. Radiosynovectomy was associated with a reduction in bleeding frequency and pain, improvements in range of motion and a reduction in the use of factor replacement.ConclusionThe literature reviewed lacks studies of sufficient methodological quality to permit systematic review and meta‐analysis. Systematic review using risk of bias assessment for observational studies should be undertaken to better evaluate the efficacy and safety of radiosynovectomy. A causal relationship between RSV and key clinical outcomes remains undetermined.
