“…Haemophilic arthropathy develops at a younger age than osteoarthritis, as reflected by the average age of patients with haemophilia who have undergone TKR, which ranges from 21 to 40 years, although patients as young as 15 years have been reported (Thomason et al, 1999;Norian et al, 2002; Although the knee is by far the most frequently replaced joint in haemophilia, arthroplasty is also used for other joints with severe arthropathy. Hip replacement in patients with haemophilia may offer significant pain relief and improved function, albeit with a higher rate of complications that lead to revisions in 20-57% of patients, although recent reports are more encouraging (Luck & Kasper, 1989;Nelson et al, 1992;Kelley et al, 1995;Lofqvist et al, 1996;Habermann et al, 2006). Other joints have been successfully replaced in patients with haemophilia, including the ankle, shoulder and elbow, although these are confined to case reports and small series (reviewed in Beeton et al, 2000;Dalzell, 2004).…”
