1.Quick Treatment: Laser therapy sessions are brief, typically lasting just a few minutes. While multiple sessions may be necessary for optimal results, the short duration allows patients to easily incorporate them into their schedules. Additionally, there's no downtime required, enabling patients to resume work or daily activities immediately after each session. Research also highlights the long-lasting benefits of laser therapy.

2.Pain-Free Procedure: Laser therapy is a non-invasive, painless treatment. It's straightforward to administer and can be conveniently performed in a physician's office without the need for specialized external facilities.

3.Drug-Free Pain Management: Laser therapy offers an effective alternative for managing pain without the use of prescription opioids, which carry a high risk of addiction and misuse. This makes it a safer option for pain relief compared to pharmacological treatments.

4.Safe and Side-Effect Free: Unlike surgery or pain medications, cold laser therapy is free from side effects. Patients can avoid the risks and complications associated with surgical procedures and lengthy recovery periods.

5.Proven Effectiveness: Backed by over 4,000 studies, cold laser therapy has demonstrated its efficacy in treating various conditions. It is also FDA-cleared, ensuring its safety and reliability for medical use.

1.Introduction:

Synovial membrane inflammation is a key factor in the pathophysiology of osteoarthritis (OA). Early OA is marked by mononuclear cell infiltration in synovial tissue and increased production of proinflammatory cytokines and other joint injury mediators. This study aimed to evaluate the effects of low-level laser therapy (LLLT) at 50 mW and 100 mW on joint inflammation induced by papain in rats. The evaluation included histopathological analysis, inflammatory cell counts (macrophages and neutrophils), and the gene and protein expression of interleukin 1-beta (IL-1β), interleukin 6 (IL-6), and tumor necrosis factor alpha (TNFα).

2.Methods:

Sixty male Wistar rats were randomly assigned to four groups (15 animals each):

Negative control group.

Positive control group (inflammation injury without treatment).

50 mW LLLT group (injury with 50 mW LLLT treatment).

100 mW LLLT group (injury with 100 mW LLLT treatment).

Joint inflammation was induced using a 4% papain solution. LLLT was applied at 808 nm, delivering 4 J (142.4 J/cm²) with a 0.028 cm² spot size for both treatment groups. Articular lavage was collected on the euthanasia day, centrifuged, and analyzed for TNFα protein expression (enzyme-linked immunosorbent assay) and IL-1β and IL-6 mRNA expression (real-time polymerase chain reaction). Histological examination of joint tissues was also conducted. Statistical comparisons between groups were performed using analysis of variance (ANOVA) with Tukey's post-hoc test. Results are presented as mean ± standard deviation, with significance set at P < 0.05.

3.Results:

The 50 mW LLLT treatment significantly reduced cellular inflammation and the expression of IL-1β and IL-6 compared to the positive control group.

The 100 mW LLLT treatment achieved a greater reduction in TNFα levels than the 50 mW treatment.

Histological analysis supported these findings, showing a more substantial reduction in the inflammatory process with the 50 mW treatment.

4.Conclusions:

Low-level laser therapy at 50 mW was more effective in modulating inflammatory mediators (IL-1β and IL-6) and reducing inflammatory cell infiltration (macrophages and neutrophils). This effect was consistent with histological evidence of decreased inflammation. While the 100 mW treatment showed superior TNFα reduction, the overall anti-inflammatory efficacy was higher with 50 mW LLLT.
