Summary
The Deepwave device effectively reduced acute pain after total knee replacement surgery. While opioid use showed a trend toward decrease, further research is needed to confirm this effect.
Area of Science:
- Neuromodulation
- Pain Management
- Orthopedic Surgery
Background:
- Acute pain and opioid use are significant challenges following total knee replacement (TKR).
- Percutaneous neuromodulation technology offers a novel approach to pain inhibition.
- Preliminary studies suggest Deepwave may outperform transcutaneous electrical nerve stimulation for pain relief.
Purpose of the Study:
- To evaluate the efficacy of the Deepwave device in reducing acute pain severity post-TKR.
- To assess the impact of Deepwave on opioid consumption in TKR patients.
Main Methods:
- A randomized controlled trial was conducted with 23 patients undergoing primary TKR.
- Patients were assigned to either the Deepwave (experimental) or sham (control) treatment group.
- Pain was assessed using the Brief Pain Inventory and Visual Analog Scale; medication intake was recorded.
Main Results:
- The experimental group showed a significant reduction in subjective pain ratings and Visual Analog Scale scores (p < 0.05).
- A trend towards decreased opioid use was observed in the Deepwave group, though not statistically significant (p = 0.09).
Conclusions:
- The Deepwave device demonstrates effectiveness in reducing subjective pain measures after TKR.
- Deepwave shows potential for decreasing opioid use post-total knee replacement, warranting further investigation.
