Brief Summary

Anterior cruciate ligament (ACL) injury is traumatic and debilitating and is typically repaired using an arthroscopic technique performed as an outpatient surgical procedure. However, many patients complain that the postoperative pain is severe for the first 48 hours following the ACL reconstruction . Effective postoperative pain management is a critical component to recovery, effective rehabilitation and patient satisfaction. Following ACL reconstruction, psychological factors are predictive of outcomes, and pain levels are inversely associated with function and quality of life assessment. ACL reconstruction procedures may reflect the complexity innervation of the anatomical areas involved, which includes the femoral nerve and its infrapatellar and saphenous branches, the obturator nerve, as well as the tibial and common peroneal branches of the sciatic nerve. Therefore, surgical variables, namely the location of surgical ports and the source of grafts used, and this creates challenge to anaesthesiologist to determine easy , safe and efficacious nerve block to be used in this setting . A recently described popliteal plexus block(PPB) is claimed to anesthetize articular branches from the posterior obturator nerve and tibial nerve. It was recently confirmed in a cadaver study that injection of 10 mL of dye into the distal end of the adductor canal spreads via the adductor hiatus to the popliteal fossa and stains the popliteal plexus (PP). A blockade of the popliteal plexus , has been claimed to produce an equivalent analgesic effect to sciatic nerve block after total knee arthroplasty without causing any motor weakness. The current study hypothesize that combined saphenous nerve block with popliteal plexus block will enhance post operative analgesia after ACL reconstruction with motor sparing of thigh and leg muscles. Thus, faster recovery and earlier post-operative physiotherapy. The objective of the current study is to evaluate analgesic effect of combined saphenous and popliteal plexus block as post -operative analgesia for anterior cruciate ligament reconstruction operation compared to standard saphenous nerve block . Patients scheduled for ACL reconstruction will be randomly assigned into one of two groups: the intervention group will receive popliteal plexus block and saphenous nerve block and the control group will receive the standard saphenous nerve block only.

Study Arms (2)

the control group

ACTIVE COMPARATOR

this group will receive post-operative saphenous nerve block by 1mg/kg plain bupivacaine 0.5% plus epinephrine 0.05 mg.

Procedure: saphenous nerve blockDrug: Plain bupivacaineDrug: 0.05 mg epinephrine

the intervention group

ACTIVE COMPARATOR

this group will receive popliteal plexus block by 1mg/kg plain bupivacaine 0.5% plus epinephrine 0.05 mg in addition to standard saphenous nerve block by 1mg/kg plain bupivacaine 0.5% plus epinephrine 0.05 mg.

Procedure: saphenous nerve blockProcedure: popliteal plexus blockDrug: Plain bupivacaineDrug: 0.05 mg epinephrine

Interventions

The skin is disinfected and the saphenous nerve is located via Ultrasound . the transducer is placed anteromedially, approximately at mid-thigh level "a high-frequency linear probe 5Y12 MHz prepared in a sterile fashion" (Phillips HD11) . The block needle (Stimuplex; Braun Medical, Bethlehem, Pa), is inserted in plane in a lateral-to-medial orientation and advanced toward the femoral artery .Once the needle tip is visualized anterior to the artery and after careful aspiration, 1-2 mL of local anesthetic is injected to confirm the proper injection site . When injection of local anesthetic does not appear to result in its spread around the femoral artery, additional needle repositions and injections may be necessary.

Also known as: adductor canal block
the control groupthe intervention group

After doing saphenous nerve block , we will move distally with the artery in the adductor canal until it moves away from the sartorius muscle to enter adductor hiatus . here , we will inject L.A above artery and so , popliteal plexus block will be accomplished

the intervention group

15ml of plain bupivacaine 0.5% will be given in both blocks

the control groupthe intervention group

0.05 mg epinephrine will be added to bupivacaine in both blocks to prolong their duration

the control groupthe intervention group
