Stopped early This study
Stopped early, before it reached the end. That can be for many reasons, including safety.

Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Summary

This study tested a temporary peripheral nerve stimulation system (SPRINT PNS) placed near the knee for up to 60 days to relieve chronic pain from osteoarthritis. Only 12 people were enrolled, and the trial was terminated early. Researchers measured pain intensity, quality of life, and pain medication use.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
temporary peripheral nerve stimulation (PNS) system (SPRINT PNS System)
What this could lead to
If it works, this could offer a non-drug option for easing chronic knee pain from osteoarthritis without permanent implants.
What could go wrong
The trial was terminated early and had only 12 participants, so results are very limited. It is unclear if the device provides lasting pain relief.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: * Age of 21 and older * Will receive a temporary PNS system for the management of chronic knee pain secondary to osteoarthritis * Be capable of subjective evaluation, able to read and understand English-written questionnaires, and able to read, understand and sign the written informed consent in English * Be willing and capable of giving informed consent * Be willing and able to comply with study-related requirements, procedures, and scheduled visits Exclusion Criteria: * No knee pain at rest * Same nerve targeted for both Radiofrequency Ablation (RFA) and Peripheral Nerve Stimulation (PNS) in less than 6 months post RFA, if applicable * Pregnancy * History of repetitive skin infections * Vulnerable populations (e.g., prisoners, minors, students, employees) * Any other condition that may interfere with the ability to participate in a clinical trial (e.g., anatomy that may interfere with lead placement, nerve damage, compromised immune system, uncontrolled diabetes) * Confounding conditions such as lumbar radiculopathy * Deep brain stimulation system, implanted active cardiac implant (e.g. pacemaker of defibrillator), or any other implantable neuro-stimulator whose stimulus current pathway may overlap the SPRINT system. * Be involved in an injury claim under current litigation * Be a recipient of temporary Social Security Disability Insurance (SSDI) benefits due to chronic pain * Have a pending or approved worker's compensation claim
