In the surgical repair of Achilles tendon ruptures, suturing is standard, although fibrin glue also has been used for repair since the 1980s. Augmentation with the plantaris longus tendon is also a popular technique; however, no study has yet compared the outcome of augmented versus only glued repair of ruptured Achilles tendons. This study compares the long-term results of surgical repair of Achilles tendon rupture with fibrin glue versus fibrin glue augmented with the plantaris longus tendon. Forty patients who had undergone Achilles tendon repair with fibrin glue took part in a follow-up examination after an average of 11.5 years. The fibrin group consisted of 16 patients and the fibrin glue augmented with plantaris longus tendon group consisted of 15 patients. The modified Thermann score (adapted from Weber) and results of an isokinetic force measurement were the same in both groups, whereas complications in the 2 groups also did not differ. We conclude that augmentation with the plantaris longus tendon is not necessary when operatively treating acute ruptured Achilles tendons with fibrin glue.
