Groups2
Neither group, or both, names a comparator, so the groups keep ClinicalTrials.gov's order.
| Group | Title | Description | With the outcome | Analysed | ClinicalTrials.gov code |
|---|---|---|---|---|---|
| Group 1 | Nerve Block | Preoperative femoral block with indwelling femoral catheter and a single shot sciatic block.~Nerve Block: Regional anesthetic nerve block using an indwelling femoral nerve catheter and a single shot sciatic nerve block using 0.5% ropivacaine. | 4 | 79 | EG000 |
| Group 2 | Periarticular Injection | Injection combination prior to skin closure.~Periarticular Injection: Periarticular local injection into the periarticular soft tissues at the time of knee replacement using a combination of ropivacaine, epinephrine, ketorolac, and morphine sulphate. Subjects in this arm received the injection combination based on three subject weight categories. | 0 | 81 | EG001 |
