“…Fuchs et al (2003) reported that hindfoot arthritis was seen in all 18 of their cases with a fused ankle, but it was predominantly located in the subtalar joint and had only a limited effect on the clinical outcome. In a prospective study, Kofoed and Stürup (1994) found subtalar arthritis in one-third of 14 fused ankles after 7 years, but none in 14 ankles with arthroplasty. Furthermore, patients with ankle fusion have substantial functional limitations, such as difficulty in walking on uneven ground and in climbing stairs, aching around the ankle with prolonged standing, walking or working, and difficulty in getting out of a bath (Muir et al 2002).…”

Background Whether or not ankles can be replaced with reasonable safety has been the subject of debate. We present the results of a nationwide series of total ankle arthroplasties.Patients and methods All Swedish hospitals that implant or have implanted modern three-component ankle prostheses reported demographic data and date of index and revision surgery to a central register. After the data had been introduced into a database, prosthetic survival rates with exchange or permanent extraction of components as endpoint were calculated.Results Of the 531 prostheses implanted, 101 had been revised by June 15, 2006. The overall survival rate at 5 years was 0.78 (95%CI: 0.74-0.82). For the three surgeons who had inserted the majority of the STAR ankles, the survival rates became significantly higher after the first 30 cases had been performed and was estimated to be 0.86 (0.80-0.93) at 5 years. Lower age at index surgery implied increased risk of revision whereas diagnosis or gender did not.Interpretation Ankle replacement is a valuable alternative to arthrodesis. However, replacing an ankle is a demanding procedure and the survival is not comparable to that after hip or knee replacement. It is obvious that with increasing experience, the results-including prosthetic survival-will improve.

“…[16][17][18][19][20][21] Rheumatoid arthritis seems to have the worst outcome after this procedure, 21,22 but OA also has a high failure rate of about 20% nonunion and about 15% deep infection. 17 Only two studies have compared ankle arthrodesis with arthroplasty, 22,23 and they found better results for the latter. The indication for each operation is still to be defined.…”

We performed 52 cemented ankle arthroplasties for painful osteoarthritis (OA) (25) or rheumatoid arthritis (RA) (27) using an ankle prosthesis with a near-anatomical design.We assessed the patients radiologically and clinically for up to 14 years using an ankle scoring system. The preoperative median scores were 29 for the OA group and 25 for the RA group and at ten years were 93.5 and 83, respectively. Six ankles in the OA group and five in the RA group required revision or arthrodesis.Survivorship analysis of the two groups showed no significant differences with 72.7% survival for the OA group and 75.5% for the RA group at 14 years.J Bone Joint Surg [Br] 1998;80-B:328-32. Received 4 August 1997; Accepted after revision 31 October 1997There has been only one study of more than 50 cases which has reported the long-term results of cemented ankle arthroplasty over ten years.1 No difference was found between patients with OA and RA, which is contrary to results from smaller series of other first-generation constrained prostheses 2-5 in which true comparisons were not made. The estimated survival rate of the arthroplasty was 61% at 15 years, and further use of the prosthesis was abandoned although pain or function were not analysed. We describe a prospective study over 14 years of patients with OA and RA which analyses the clinical and radiological differences between the groups and the long-term survivorship of the prosthesis.

“…Como estímulo extra, além da tendência atual de preservação da atividade e qualidade de vida, surgem as observações inequívocas acerca das complicações associadas à artrodese do tornozelo (1) e da superioridade funcional da artroplastia quando comparada com a fusão, ambas em longo prazo (11)(12)(13) . Os recentes avanços na compreensão da biomecânica e fisiologia do tornozelo humano, além da experiência acumulada com as sucessivas falhas nos desenhos das próteses no passado, determinaram o surgimento das próteses não constritas, com três componentes, dotadas Sua implantação, no entanto, é repleta de detalhes técnicos e passos delicados, dos quais podem resultar erros de difícil correção ou complicações sérias.…”

RESUMOA artrose do tornozelo vem se tornando mais comum a cada dia. A busca por soluções que preservem a função articular fez surgir uma nova geração de próteses com três componentes e maior liberdade de movimento. Neste trabalho, apresentam-se os resultados obtidos em 10 pacientes tratados com a prótese HIN-TEGRA (Integra, New Deal), em ação conjunta dos Grupos do Tornozelo e Pé do DOT da Unifesp-Escola Paulista de Medicina e IOT da Faculdade de Medicina da USP-Universidade de São Paulo. Os 10 pacientes (seis mulheres e quatro homens), com idade variando de 29 a 66 anos, foram submetidos ao tratamento cirúrgico segundo a técnica de Hinterman entre janeiro e junho de 2005. Foram avaliados em intervalos predeterminados e os dados foram submetidos à análise estatística. A mobilidade do tornozelo apresentou melhora significante com a cirurgia realizada. Radiologicamente, não foram detectados sinais de soltura ou falhas nos componentes prostéticos de nenhum dos pacientes estudados. A taxa de complicações nessa amostra foi alta, mas equivalente às de outros autores e representa diretamente a curva de aprendizado relacionada com esse tipo de procedimento. Ao final de quatro anos, observaram-se significativa redução da dor e melhora do padrão funcional dos pacientes com os escores da AOFAS e de Hinterman, apontando para 20% de excelentes, 70% de bons e 10% de maus resultados. O tratamento da artrose do tornozelo através da artroplastia total com o modelo HINTE-GRA, foi capaz de oferecer bons resultados no tempo médio de observação de quatro anos.
