Subcutaneous rupture of the Achilles tendon

A series of 27 ruptures of the tendo Achillis are reported. Samples of tendon tissue, taken both at the site of rupture and at a distance from it, were histologically examined. Four different surgical procedures were performed. All patients showed marked degenerative changes of the tendon tissue. No definite relationship was found between the surgical procedure employed and functional results obtained. These were rated as excellent in 12 cases, good in 11 and fair in four. Only minor complications attending the operation occurred. We emphasize the superiority of open repair over conservative treatment.
