Outcome Measures

Primary Outcomes (3)

  • postoperative pain degree

    two groups of patients were evaluated and compared as regard the Degree of postoperative pain using Numerical Rating Scale (NRS) which consist of a series of numbers rating pain intensity, typically from 0 to 10 with 0 being "no pain" and 10 being "the worst pain imaginable.", So that the higher the number the worse is the pain . The numerical rating scale is recorded each 4hours at the first 48 hours.

    48hours

  • The first time to need analgesic rescue .

    The first time to need analgesic rescue when (Numerical rating scale score ≥ 4 which means moderate to severe pain ) is recorded in hours (the Numerical rating scale consist of a series of numbers rating pain intensity, typically from 0 to 10 with 0 being "no pain" 1to3 being "mild pain,4to6 being "moderate pain "and 7to10 being "sever pain" . So that the higher the number the worse is the pain.

    2days

  • the total amount of analgesic rescues needed measured in numbers

    Number of analgesic rescues needed when patient's pain is moderate to sever

    2days

Secondary Outcomes (7)

  • Sex influence on degree of pain

    At the time of patients' enrollment in the study.

  • Age

  • BMI(kg/m2)

    At the time of patients'enrollment in the study.

  • Motor recovery

    2days

  • Mobility recovery

  • +2 more secondary outcomes

Study Arms (2)

adductor canal block (ACB) alone

ACTIVE COMPARATOR

received ultrasound guided adductor canal block (ACB) alone using 22 Gag spinal needle with injection of 15ml 0.25% bupivacaine with addition of 2mg dexamethasone and 2.5mcg /ml epinephrine as an adjuvant to prolong its action.

Procedure: spinal anesthesiaProcedure: Adductor Canal Block

adductor canal block (ACB)in addition to (IPACK) block

ACTIVE COMPARATOR

received ultrasound guided adductor canal block (ACB) as group A, in addition to ultrasound guided infiltration of the interspace between popliteal artery and the capsule of posterior knee (IPACK) block with either of the two previously mentioned approaches, using 22Gag spinal needle injecting 20ml 0.25%bupivacaine with addition of 2mg dexamethasone and 2.5mcg /ml epinephrine as an adjuvant to prolong its action.

Procedure: spinal anesthesiaProcedure: Adductor Canal BlockProcedure: interspace between Popliteal artery and capsule of knee (IPACK) block

Interventions

spinal anesthesia using 15 mg 0.5% hyperbaric bupivacaine in the sitting position at L3-4 or L4-5 intervertebral space.

local anesthetic spread around the saphenous nerve in the adductor canal ultrasound guided using 22 Gag spinal needle with injection of 15ml 0.25% bupivacaine with addition of 2mg dexamethasone and 2.5mcg /ml epinephrine as an adjuvant to prolong its action.

ultrasound guided Local anesthetic infiltration over the posterior aspect of the femur underneath the popliteal artery targeting the genicular nerves which are the articular branches of tibial and common peroneal nerves, posterior branches of the obturator nerve, and medial genicular nerve using 22Gag spinal needle injecting 20ml 0.25%bupivacaine with addition of 2mg dexamethasone and 2.5mcg /ml epinephrine as an adjuvant to prolong its action.
