Study Arms:
- Genicular nerve block with bupivacaine (Type: ACTIVE_COMPARATOR): The ultrasound-guided genicular nerve block will be performed at the site of the superior lateral, the superior medial, and the inferior medial genicular nerves. Color Doppler will be used to identify the arterial structures which serve as landmarks for the corresponding nerves.~After skin local anesthetic infiltration, a 10 cm 21G insulated block needle will be inserted and aligned with the ultrasound scanning plane. Once satisfactory position of the needle is confirmed, 5mL of a solution containing 15 ml 0.25% bupivacaine with 2mg dexamethasone or 5mL saline will be slowly injected. Spread of local anesthetic will be documented adjacent to the target nerve. This procedure will be performed at the site of the three genicular nerves described.
- Genicular nerve block with saline (Type: PLACEBO_COMPARATOR): The ultrasound-guided genicular nerve block will be performed at the site of the superior lateral, the superior medial, and the inferior medial genicular nerves. Color Doppler will be used to identify the arterial structures which serve as landmarks for the corresponding nerves.~After skin local anesthetic infiltration, a 10 cm 21G insulated block needle will be inserted and aligned with the ultrasound scanning plane (in-plane approach). Once satisfactory position of the needle time is confirmed, 5mL of a saline will be slowly injected. Spread of local anesthetic will be documented adjacent to the target nerve. This procedure will be performed at the site of the three genicular nerves described.

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