Detailed Description
Total knee arthroplasty (TKA)is a common orthopedic surgical procedure. Optimal pain control is necessary for early recovery and discharge. TKA is considered one of the more painful surgical procedures, peripheral nerve blocks and multimodal analgesia are incorporated into clinical practice to provide patient comfort, decrease postoperative opioid requirement, facilitate early ambulation and enhance patient satisfaction.Adductor canal nerve block (ACB) and intraoperative periarticular infiltration (PAI) are routine clinical practice followed at our institute for postoperative pain control. Although ACB provided analgesia to peripatellar and anterior intra-articular aspect of knee joint, it does not relieve posterior knee pain which can be moderate to severe in intensity. Many techniques have been employed for posterior knee pain including sciatic nerve block and infiltration between popliteal artery and posterior capsule of the knee joint (IPACK) with limited success. Sciatic nerve block is considered gold standard but is rarely used due to associated motor weakness, which may delay ambulation and decrease participation in physical therapy postoperatively . In recent times IPACK block has gained popularity but there are concerns about local anesthetic injection close to surgical field and total dose of local anesthetic exceeding the recommended amount if combined with periarticular infiltration as is the practice at our institute.
SPANK block was described in 2015 by Kardash et al for posterior knee pain while sparing motor function. The block is performed at the level of femoral shaft above the femoral epicondyle, on the medial side of the leg, with needle positioned just superficial to posteromedial femoral periosteum and 15 ml of local anesthetic is injected, decreasing concerns for local anesthetic toxicity, and invasiveness close to surgical field as compared to IPACK block which requires 30 ml of local anesthetic.
Efficacy of SPANK block has been demonstrated as rescue analgesic for posterior knee pain after TKA, and a trial is underway to evaluate efficacy of ACB an SPANK block versus ACB alone [5].There is no literature evaluating benefit of SPANK block when added to ACB and PAI which is a standard practice.
If SPANK block proves to be effective in controlling posterior knee pain, with motor sparing effect it can help reduce postoperative opioid requirement, help achieve same day discharge and prove to be another small step towards fighting opioid epidemic.
Hence, we propose this study to evaluate added benefit of SPANK block to ACB and PAI with regards to postoperative pain control.

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
ACTIVE_COMPARATOR: Adductor canal block (ACB)
|
The block is performed in supine position under ultrasound guidance using 22 G Touhy needle advanced in plane and 15 cc of 0.5% Ropivacaine ( local anesthetic) with dexmedetomidine 20-30 mcg depending on the age of the patient is injected at midthigh level lateral to the femoral artery in adductor canal to provide sensory blockade to the anterior aspect of the knee.
ropivacaine 0.5% will be use in the block
|
EXPERIMENTAL: Adductor canal block plus SPANK block
|
The block is performed in supine position under ultrasound guidance using 22 G Touhy needle advanced in plane and 15 cc of 0.5% Ropivacaine ( local anesthetic) with dexmedetomidine 20-30 mcg depending on the age of the patient is injected at midthigh level lateral to the femoral artery in adductor canal to provide sensory blockade to the anterior aspect of the knee.
ropivacaine 0.5% will be use in the block
SPANK: The block is performed in supine position, using 22 G Touhy needle, under ultrasound guidance, needle is advanced in plane to posteromedial shaft of femur taking care to avoid popliteal artery, and 0.5% ropivacaine 15 cc, dexmedetomidine 20-30mcg and dexamethasone 4 mg is injected into inner thigh above the knee provide sensory block to posterior aspect of the knee.
