Design outcomes
Primary
| Measure | Time frame |
|---|---|
| The main endpoints of this study are the changes in serum concentrations of biomarkers of collagen metabolism perioperatively and up to two weeks after surgery. These biomarkers represent bone and cartilage synthesis (N-terminal propeptide of type I and type II collagen, respectively: P1NP, P2NP) and breakdown (C-terminal telopeptide of type I and type II collagen, respectively: CTx1, CTx2). | — |
Secondary
| Measure | Time frame |
|---|---|
| Secondary endpoints include changes in plasma amino acid concentrations and pain and functional outcomes. | — |
