Non-operative management of Achilles tendon rupture equivalent to the surgical repair .
Este estudo foi identificado como tendo um impacto potencialmente elevado.
A métrica de Alto Impacto da OE, baseada em IA, estima a influência que um artigo poderá ter, integrando sinais da revista em que foi publicado e do conteúdo científico do próprio artigo.
Desenvolvido com recurso ao mais avançado processamento de linguagem natural, o modelo High Impact da OE prevê com maior precisão o desempenho futuro de um estudo em termos de citações do que o fator de impacto da revista por si só.
Isto permite o reconhecimento precoce de investigação clinicamente significativa e ajuda os leitores a concentrarem-se nos artigos com maior probabilidade de moldar a prática futura.

OE Journal. 2013;1(2):73 J Bone Joint Surg Am. 2010 Dec 1;92(17):2767-75. Epub 2010 Oct 29.144 patients with primary complete Achilles tendon rupture were randomized to be treated with either a surgical repair and accelerated functional rehabilitation or with only the accelerated functional rehabilitation. Over the course of a two year follow up, it was observed that Achilles tendon rupture led to clinically similar results between the two treatment groups.
Was the allocation sequence adequately generated?
Was allocation adequately concealed?
Blinding Treatment Providers: Was knowledge of the allocated interventions adequately prevented?
Blinding Outcome Assessors: Was knowledge of the allocated interventions adequately prevented?
Blinding Patients: Was knowledge of the allocated interventions adequately prevented?
Was loss to follow-up (missing outcome data) infrequent?
Are reports of the study free of suggestion of selective outcome reporting?
Were outcomes objective, patient-important and assessed in a manner to limit bias (ie. duplicate assessors, Independent assessors)?
Was the sample size sufficiently large to assure a balance of prognosis and sufficiently large number of outcome events?
Was investigator expertise/experience with both treatment and control techniques likely the same (ie.were criteria for surgeon participation/expertise provided)?

O Índice de Fragilidade é uma ferramenta que auxilia na interpretação de achados significativos, fornecendo uma medida de força para um resultado. O Índice de Fragilidade representa o número de eventos consecutivos que precisam de ser adicionados a um resultado dicotómico para que o resultado deixe de ser significativo. Um número pequeno representa um resultado mais fraco e um número grande representa um resultado mais forte.
Porque é que este estudo era necessário agora?
Achilles tendon rupture is a common sporting injury in adults with an increasing incidence due to continued sporting activity with growing age. So far evidence had favored surgical repair to be better in preventing re-rupture rates. However, the treatment of choice still remains controversial. Early weight-bearing with protected range of motion demonstrates better range of motion, strength, and return to activity, while minimizing re-ruptures or possibility of healing in a lengthened position. This study aimed to compare outcome of patients with acute Achilles tendon ruptures, who had been treated with operative repair and accelerated functional rehabilitation, with outcomes of similar patients who had been treated with accelerated functional rehabilitation alone.
Qual era a principal questão de investigação?
Are there any long-term differences in the results between patients receiving operative repair and accelerated functional rehabilitation versus those patients receiving accelerated functional rehabilitation alone, in the two-year post-operative period?
- At the 2-year follow-up, re-rupture occurred in two patients in the operative group at one and three months after injury and in three patients in the nonoperative group at one, two, and three months after injury.
- There was significant difference in the plantar flexion strength ratio (affected to unaffected limb) at 240 degrees at two years (mean difference, 14.15%; 95% CI, 1.12% to 27.19%; p = 0.03) in favor of the operative group.
- The mean range of dorsiflexion was 20.3 degrees +/- 12 degrees in the operative group and 17.9 degrees +/- 6.0 degrees in the nonoperative group. The mean range of plantar flexion was 44.5 degrees +/- 8.4 degrees in the operative group and 46.8 degrees +/- 8.5 degrees in the nonoperative group.
- The side-to-side difference in plantar flexion range of motion was greater in the nonoperative group than in the operative group (mean difference between groups, 2.21 degrees; 95% CI, 3.9 degrees to 0.5 degrees; p = 0.01)
- The mean side-to-side difference in calf circumference was 1.7 +/- 2.0 cm in the operative group and 1.5 +/- 5.6 cm in the nonoperative group. This difference was not significant (mean difference between groups, 0.2 cm; 95% CI, 1.8 to 1.3 cm; p = 0.75).
- The mean Leppilahti score was 82.6 +/- 11.1 points in the operative group and 82.2 +/- 12.3 points in the nonoperative group. These values were not significant (mean difference: 0.4 point; 95% CI, 5.4 to 5.0 points; p = 0.89).
- Study pitfalls, however, included no specification of intent to treat analysis, a largely male population, and an under-powered sample size.
De que é que me devo lembrar mais?
The results of this study supported the use of accelerated functional rehabilitation and nonoperative treatment for acute Achilles tendon ruptures. All measured outcomes were clinically similar to those experienced for operative treatment. However, this study was under-powered.
Como é que isto afectará o tratamento dos meus doentes?
In patients with Achilles tendon rupture, accelerated functional rehabilitation appears to be effective when used after surgical and nonsurgical treatments. Further methodologically sound studies with sufficient power are necessary to confirm these findings.
