Summary
Peripheral nerve stimulation (PNS) offers significant long-term pain relief for chronic knee pain sufferers. This study found that PNS is a safe and effective treatment, with most patients experiencing over 50% pain reduction.
Area of Science:
- Orthopedics
- Neurology
- Pain Management
Background:
- Chronic knee pain affects mobility and quality of life.
- Peripheral nerve stimulation (PNS) is a growing treatment for chronic pain.
- Research on PNS for chronic knee pain is limited.
Purpose of the Study:
- To evaluate the safety and efficacy of PNS for chronic knee pain.
- To assess long-term pain reduction following PNS implantation.
Main Methods:
- Retrospective case series of 14 patients (17 cases) treated with PNS for chronic knee pain.
- Data collected via chart review and patient phone calls.
- Primary outcome: percent pain reduction at six months post-implantation.
Main Results:
- Mean pain reduction of 52% at six months.
- 75% of patients reported ≥50% pain reduction at six months.
- No adverse events related to PNS implantation or stimulation were reported.
Conclusions:
- PNS is a safe and effective treatment for chronic knee pain.
- PNS demonstrates long-term therapeutic benefits for knee pain.
- Further research is needed to identify factors predicting treatment response.

01:29Blood and Nerve Supply to the Bones
Bones are dynamic organs that require a rich supply of oxygen and nutrients. Around 5% to 10% of the cardiac output supplies blood to the bones. A typical long bone has three main sources: the nutrient artery, the metaphyseal and epiphyseal arteries, and the periosteal arteries.
Nutrient Artery
The nutrient artery is the main blood vessel that enters the diaphysis via the nutrient foramen. While most long bones have only one nutrient foramen, large bones, such as the femur, may have two. This...

01:23Degenerative Disc Disease ll: Pathophysiology
The symptoms of degenerative disc disease arise from a combination of mechanical compression, vascular compromise, and biochemical inflammation, which together disrupt nerve function and produce pain.Mechanical CompressionDisc degeneration reduces height and elasticity, predisposing to herniation of the nucleus pulposus, a major cause of radicular pain. Herniations may be protrusion (bulging with intact annulus), extrusion (nucleus extends beyond disc but remains connected), or sequestration...
