Input: Twelve trials involving 844 participants were included. One trial tested two comparisons. Quality assessment revealed a poor level of methodological rigour in many studies, particularly with regard to concealment of allocation and the lack of assessor blinding. Open surgical treatment compared with non-surgical treatment (6 trials, 536 participants) was associated with a statistically significant lower risk of rerupture (risk ratio (RR) 0.41, 95% confidence interval (CI) 0.21 to 0.77), but a higher risk of other complications including infection (RR 4.89, 95% CI 1.09 to 21.91), adhesions and disturbed skin sensibility (numbness). Functional status including sporting activity was variably and often incompletely reported, including frequent use of non standardised outcome measures, and the results were inconclusive. Open surgical repair compared with percutaneous repair (4 trials, 174 participants) was associated with a higher risk of infection (RR 9.32, 95% CI 1.77 to 49.16). These figures should be interpreted with caution because of the small numbers involved. Similarly, no definitive conclusions could be made regarding different tendon repair techniques (3 trials, 147 participants). Open surgical treatment of acute Achilles tendon ruptures significantly reduces the risk of rerupture compared with non-surgical treatment, but produces significantly higher risks of other complications, including wound infection. The latter may be reduced by performing surgery percutaneously.
Output:

Twelve trials including 794 participants acute Achilles tendon rupture were included. The majority of participants were male, and the average ages of the study populations were between 36 to 41 years. Many of the trials had flawed methods that undermined the reliability of their results. Open surgical treatment compared with non-surgical treatment (6 studies, 502 participants) was associated with a lower risk of rerupture, but a higher risk of other complications such as infection, adhesions and disturbed skin sensibility (numbness and tingling). There were insufficient and inconclusive data on function and sporting activities. Percutaneous repair (involving stab incisions through which the repair suture is passed through without direct exposure of the tendon) compared with open repair (4 studies, 174 participants) was associated with a lower risk of infection. These figures should be interpreted with caution because of the small numbers involved. Similarly, no definitive conclusions could be made regarding different tendon repair techniques (3 studies, 141 participants).
