[Achilles tendon rupture--early functional and surgical options with special emphasis on rehabilitation issues].
Achilles tendon ruptures are one end of a continuum starting with the healthy Achilles tendon via the thickened and painful tendinopathic Achilles tendon with neovascularisation to the complete tendon rupture. Often times chinolone antibiotics, cortisone therapy and valgus foot axis are associated risk factors. Incidence of Achilles tendon ruptures is estimated to be 10/100 000 per year with a mean age of 35-40 years. Physical activity is encountered in 75 % cases of Achilles tendon ruptures. Running is associated with Achilles tendinopathy as the predominant overuse injury in an analysis among 291 athletes with 10 million kilometers exposure. The Achilles tendinopathic rate was 0.016/1000 km differentiated in 0.008/1000 km mid-portion tendinopathy and 0.005/1000 km insertional tendinopathy. Achilles tendinopathy in running overuse injuries is followed by runner's knee (0.013/1000 km), shin splint (0.0104/1000 km) and plantar fasciitis (0.0054/1000 km). Dynamic ultrasound in 20 degrees plantar flexion is of utmost importance for therapeutic decision making. With an adaptation rate of 75 % or more of the ruptured tendon in 20 degrees plantar flexion and a high patient's compliance we perform an early functional conservative treatment regimen in Achilles tendon ruptures. In almost all other cases the percutaneous Achilles tendon repair is indicated, where nervus suralis lesions have to be appreciated. The vulnerable zone is 10-12 cm proximal to the calcaneus at the lateral border of the Achilles tendon with the sural nerve in close proximity with the tendon. Early functional rehabilitation is not associated with a higher risk of rerupture but with improved subjective assessments and should therefore be advocated.
