Electrical Stimulation for the Treatment of Pain Following Total Knee Arthroplasty Using the SPRINT Beta System
open to eligible people ages 21–90
The purpose of this study is to determine if electrical stimulation (small levels of electricity) in addition to the standard of care can safely and effectively reduce pain following total knee replacement more than the standard of care, alone. This study involves a device called the SPRINT Beta System. The SPRINT Beta System delivers mild electrical stimulation to nerves in the leg that received the knee replacement. The SPRINT Beta System includes a small wire (called a "lead") that is placed through the skin in the upper leg. It also includes a device worn on the body that delivers stimulation (called the SPRINT Beta Stimulator). About half the subjects in this study will receive the SPRINT Beta system (treatment group) and half will not (control group). Both groups will receive the standard of care.

Pain is a symptom that drives hospital admissions, and pain management is required by most patients during their hospital stay. Further, the use of medications such as opioids can lead to upward-spiraling doses, especially among chronic pain patients whose resource utilization rates are high. Many initiatives aim to reduce the costs of these "high-resource utilizing" patients. One exciting aspect of improving the management of pain is that this may help prevent patients from ever becoming high-cost in the first place. The purpose of this study is to examine the impacts of an early intervention pathway, in comparison to the current standard of care, for the treatment of pain in opioid tolerant patients. It is hypothesized that patients randomized to the early intervention pathway, in comparison to the control, will lead to decreased costs of care, a reduction in opioid usage within 3 and 6 months, and decrease in hospital readmission rates.

The moderate-to-severe pain many patients experience following orthopedic surgery is often treated with opioids, which are associated with side effects such as nausea/vomiting, sedation, and respiratory depression (and a risk of abuse). Potent site-specific analgesia with fewer side effects may be provided with a "continuous peripheral nerve block," which involves the percutaneous insertion of a catheter adjacent to the peripheral nerve(s) supplying a surgical site. Local anesthetic is introduced via the catheter. However, there are major problems with continuous nerve blocks that have dramatically limited their use outside academic centers. Percutaneous peripheral nerve stimulation (PNS) or "nerve modulation" is an alternative method of pain control involving the insertion of an electrical lead through an introducing needle—obviating an open surgical incision for placement—followed by the introduction of electric current to produce analgesia. This modality has been used to treat chronic pain, but it has not been evaluated with a randomized, controlled study when applied to acute pain management (post-surgical analgesia). This temporary therapy has multiple theoretical benefits over existing analgesics, such as a lack of systemic side effects (e.g., nausea, respiratory depression), an absence of induced muscle weakness, and a reduced risk of adverse events (e.g. infection). The purpose of the proposed randomized, double-masked, placebo-controlled, crossover, feasibility study is to explore the possibility of treating postoperative pain with ultrasound-guided percutaneous PNS and, if so, to help power a subsequent definitive randomized, controlled trial.

This study will be a double-blinded randomized controlled trial analyzing all patients who will undergo major lower extremity amputations by the vascular surgery service at UCSF Fresno between July 2017 and June 2018 to determine if regional nerve blocks (sciatic and femoral) have any effect on postoperative pain control, narcotic requirements, and length of stay compared with standard post-operative narcotic regimens.
