Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Main Objective: To evaluate the influence of an adjuvant, intravenous therapy with zoledronic acid (single dose) on healing after arthroscopic repair of chronic rotator cuff tears.;Secondary Objective: not applicable;Primary end point(s): investigation of zoledronic acid on tendon integrity via magnetic resonance imaging at six months , twelve months , twentyfour and sixty months after arthroscopic repair of chronic rotator cuff lesions.;Timepoint(s) of evaluation of this end point: six months, twelve months, 24 and 60 months after arthroscopic repair of chronic rotator cuff lesions. | — |
Secondary
| Measure | Time frame |
|---|---|
| Secondary end point(s): Examination of bone metabolism, micro-RNA , specific clinical test concerning shoulder function as well as collection of functional questionaires to investigate the muscular regeneration by zoledronic acid;Timepoint(s) of evaluation of this end point: 2 day, 4 week, 3 months, 6 months , 12 months, 24 months and 60 months after arthroscopic repair of chronic rotator cuff lesions. An interim analysis is planned after all 80 patients have completed the “3 month postoperative” visit. This will be expected between Q1/ 2025 and Q4/ 2025. | — |
