Detailní popis
The objectives of this study are:
- Evaluate the role of sciatic nerve block in total knee replacement. There is conflicting data as to whether sciatic nerve block would provide significant analgesic benefit in addition to femoral nerve block and the usual multimodal and preemptive analgesic regimen for TKA.
- Investigate the efficacy of single-shot sciatic nerve block on early rehabilitation, functional recovery and patient satisfaction.
- Evaluate the previously described technique of local anesthetic infiltration into the posterior capsule/fat pad of the knee as an alternative technique to sciatic nerve block in providing analgesia to the posterior aspect of the knee in this select group of patients.
- Investigate the efficacy of local anesthetic infiltration into the posterior capsule/fat pad of the knee on early rehabilitation, functional recovery and patient satisfaction.
Study Design:
All patients will have a femoral nerve block (FNB) and spinal anesthesia.
Patients will be randomized into one of the 3 possible groups:
Group 1: Femoral nerve block + Sciatic nerve block + Spinal anesthesia + Infiltration of normal saline at the end of surgery
Group 2: Femoral nerve block + Sham Sciatic nerve block + Spinal anesthesia + Infiltration of local anesthetic at the end of surgery.
Group 3: Femoral nerve block + Sham Sciatic nerve block + Spinal anesthesia. + Infiltration of normal saline at the end of surgery.
In summary, this study will help further define the role of sciatic nerve block as well as the alternative technique of local anesthetic infiltration in the perioperative analgesic regimen of total knee arthroplasty surgery, in an effort to develop a standardized perioperative protocol for this patient population. The advent of this protocol should allow reduced risk, improved analgesia, and potentially earlier discharged from hospital with better function.
