Experimental: Nerve Block
Preoperative femoral block with indwelling femoral catheter and a single shot sciatic block.
Drug: Nerve Block
Regional anesthetic nerve block using an indwelling femoral nerve catheter and a single shot sciatic nerve block using 0.5% ropivacaine.
Other Name: Naropin
Active Comparator: Periarticular Injection
Injection combination prior to skin closure.
Drug: 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.
- Post-Operative Pain [ Time Frame: Afternoon on post-operative Day 1, approximately 14:00 ]Pain was measured using a linear analog scale for pain, with a scale from 0 (no pain) to 10 points (worst possible pain).
- Pain Scores in the Per-protocol Subset (Participants Who Received the Allocated Treatment) [ Time Frame: Afternoon on post-operative Day 1, approximately 14:00 ]Pain was measured using a linear analog scale for pain, with a scale from 0 (no pain) to 10 points (worst possible pain).
- Narcotic Use [ Time Frame: Intraoperative, Day of surgery, Post-Operative Day 1, Post-Operative Day 2 ]Use of additional narcotic medications (as needed), measured in morphine equivalents.
- Straight-leg Raise [ Time Frame: Day 1 morning (AM), Day 1 afternoon (PM), Day 2 morning, Day 2 afternoon ]Post-operative quadriceps function was measured by the number of participants who could perform a straight-leg raise.
- Length of Stay in Hospital [ Time Frame: Approximately 2 days after surgery ]Length of stay data were calculated from the medical record.
- Number of Subjects Who Experienced Neurological Changes Postoperatively [ Time Frame: 6 weeks postoperative ]Participants were questioned at the 6 weeks follow-up visit regarding any neurological changes that were not present preoperatively.
