Study Arms:
- Peripheral Nerve Block (PNB) (Type: ACTIVE_COMPARATOR): This group received a continuous femoral nerve block and a single injection sciatic nerve block consisting of the following: Peripheral nerve blocks with Bupivacaine.
- Ropivacaine (PAI-R) (Type: ACTIVE_COMPARATOR): This group received intra articular injection with Ropivacaine, a total volume of 120 milliliters (mL) injected in the periarticular structures by the surgeon. Following the current, standardized practice for periarticular infiltration, approximately 30 - 40 mL of solution was injected into the posterior capsule just prior to cementing the implants in place and 40 - 50 mL of solution injected into the medial and lateral retinaculum while the cement was hardening and prior to deflation of the tourniquet. The remaining volume of approximately 40 mL was injected into the quadriceps tendon and subcutaneous tissue prior to skin closure.
- Liposomal Bupivacaine (PAI-L) (Type: ACTIVE_COMPARATOR): This group received Intra articular injection with liposomal bupivacaine, a total volume of 120 milliliters (mL) injected in the periarticular structures by the surgeon. Following the current, standardized practice for periarticular infiltration, approximately 30 - 40 mL of solution was injected into the posterior capsule just prior to cementing the implants in place and 40 - 50 mL of solution injected into the medial and lateral retinaculum while the cement was hardening and prior to deflation of the tourniquet. The remaining volume of approximately 40 mL was injected into the quadriceps tendon and subcutaneous tissue prior to skin closure.

Based on this trial design, predict the completion outcome and termination type (if applicable).
