Introduction: At the 2nd Orthopaedic Clinic of Turin the subcutaneous rupture of the Achillis tendon is treated with the Ma-Grifþth technique, followed by cast for eight weeks, weight bearing is possible after 2 months. Aim of this work is to evaluate 61 patients operated. Materials and methods: 61 patients were evaluated, divided into 2 groups: group A) 20 male patients treated from 1991 to 1996, mean age 37 years, follow-up 3,3 years, in the 1997 they had a clinical, echosonographic and isokinetic evaluation. Group B) 41 patients, 4 female, treated from 1997 to may 2002, mean age 37,5, mean follow-up 3,6 years, in the 2002 they were clinically evaluated. Results: Group A): the ecographic analysis revealed the thickening of the operated tendon, the isokinetich analysis revealed the same range of movement of the not-affected side, without lack of strength. Group A and B): at the clinical evaluation a normal walking and all the patients came back to the athletic activities in 5 months.

The 5% of the cases presented cicatricial adhaesions, the 10% of the cases presented a light hypoesthesia of the sural nerve. Only one rupture occurred after the re-beginning of the sport activity. Conclusion: This technique has several vantages, like the mini-invasivity, the rapidity of esecution and a low rate of severe complications and gave us good results, therefore we think that could be indicated in the non agonistic patient.
