Clinical Trial Summary

This is a prospective, single-center, placebo-controlled, non-comparative, phase II study to evaluate the influence of an adjuvant, intravenous therapy with zoledronic acid (single dose) on healing after arthroscopic repair of chronic rotator cuff tears.

The study including its financial support was approved by the medical director of the General Accident Insurance Institution (AUVA) , Dr. Roland Frank.

Hypothesis to prove: Adjuvant intravenous therapy with zoledronic acid does improve tendon healing after arthroscopic reconstruction of chronic rotator cuff tears compared to a control group without adjuvant therapy with zoledronic acid.,
