Long-term follow-up of a tenotomized Achilles tendon reveals healing with formation of a tendonlike structure between the cut tendon ends. A prospective study to show sonographic healing stages was designed. Twelve patients (21 Achilles tendons) with the diagnosis of cerebral palsy, spastic diplegia, and shortening of their Achilles tendons underwent a tenomuscular release. The healing process was documented by monthly ultrasound studies. Overall, 102 examinations were done, with a mean follow-up of 5.3 months. The authors found six distinct healing stages, with no significant change occurring in the length of the primary gap at the tenotomy site throughout healing. Based on these results, the authors conclude that sonographic healing stages of the cut Achilles tendon can be defined and staged. They also suggest that transverse tenotomy at the tenomuscular junction is a safe method, with no risk of over-lengthening.
