Summary

Comparison of the analgesic and physical recovery effect of genicular nerve block (GNB) alone and (GNB + infiltration between popliteal artery and posterior capsule of the knee (IPACK) in patients undergoing total knee replacement

Conditions

  • Postoperative Pain

Interventions

PROCEDURE

GNB plus standard analgesia

When patients are in supine position with a pillow under the popliteal fossa, we will target points next to superior medial, superior lateral, and inferior medial genicular arteries to block the superior medial, superior lateral, and inferior medial branches of genicular nerve. For identification, we will use color Doppler near the periosteal areas (the junctions of the epicondyle with the shafts of the femur and tibia, accordingly). using a 12 MHz linear transducer (XarioTM SSA-660A, Toshiba Medical Systems Corporation, Otawara, Japan) positioned parallel to the shaft of the long bones in the legs, the needle will be inserted ( in plane technique in the long-axis view) and a 2.5 mL of bupivacaine (5%) will be injected at each target points.standard analgesia will be given post-operativelly (paracetamol 1 gm/ three times a daily and meloxicam (15 mg)once a day)

PROCEDURE

GNB plus IPACK block plus standard analgesia

IPACK block will be done when the patients in supine position with the knee flexed in 45 degree. using a low frequency transducer at a depth of 3.5-4 cm positioned transversely, 2-3 cm above the patella and over the medial aspect of the knee, we will identify the distal part of the shaft of the femur and the popliteal artery with sliding the transducer proximally and distally (If the two femoral condyles appear first, proximal sliding of the probe, so the humps of the femoral condyles will disappeared and the flat metaphysis will appeared). With advancement of the needle in plane toward the space between the popliteal artery and the femur, 15 ml of bupivacaine 0.5% will be injected. The genicular nerve block will be done as in group G and standard analgesia will be given post-operative as in group G

DRUG

standard analgesia (paracetamol and meloxicam)

(paracetamol 1 gm 3 times a daily and meloxicam (15 mg) once aday.
