Abstract
PURPOSE To evaluate morphological aspects and inducible nitric oxide synthase (iNOS) gene and protein expression in a model of acute inflammation. METHODS Thirty-six female Wistar rats were assigned into three groups: control (saline, n = 12), sham (arthritis, n = 12), and PBM (arthritis and photobiomodulation, n = 12). Arthritis induction was performed with 200 μg of intra-articular Zymosan in sham and PBM animals. PBM was performed 24 h after induction with a laser device (λ = 808 nm, 25 mW of nominal power, fluence of 20 J/cm2, beam area of 0.02 mm2, time of 33 s, total energy of 0.825 J) with punctual and single dose application. Morphological analysis of joint structure (HE) and immunohistochemistry (anti-iNOS antibody) were performed on knee samples, and synovial tissue was submitted to RNA extraction, cDNA synthesis and gene expression analysis by quantitative polymerase chain reaction. Statistical analyses were performed with p < 0.05. RESULTS It was observed an increase in the thickness of the synovial lining epithelium and inflammatory infiltrate in sham compared to PBM. Gene expression analysis showed higher iNOS expression in PBM, and iNOS protein expression decreased in PBM compared to sham. CONCLUSIONS Photobiomodulation decreased inflammation in PBM animals, upregulated iNOS gene expression, however down egulated protein expression compared to sham.

Abstract
PURPOSE The objective of present study was to investigate the therapeutic effects of high tibial osteotomy (HTO) combined with platelet-rich plasma (PRP) for severe knee osteoarthritis (KOA). METHODS This was a double-blinded, randomized, placebo-controlled trial. The participants were randomly divided by computerderived random charts into 3 groups: 24 participants in group A (24 knees) received a treatment option of HTO combined with PRP, 25 participants in group B (25 knees) received a treatment program of HTO combined with hyaluronic acid, and 25 participants in group C (25 knees) received a treatment method of HTO combined with normal saline (NS) (physiological control/placebo). The Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) and visual analog scale (VAS) were measured preoperatively and at the final follow-up. Status of articular cartilage was assessed according to the International Cartilage Repair Society grade and the presence of newly formed cartilaginous tissue by arthroscopy. MRI was completed of knee joint to measure the cartilaginous thickness. RESULTS Compared to Group B and C, the final follow-up results of knee function in Group A were significantly different (P < 0.001), such as the total WOMAC score 18.54 (SD 4.17), the VAS score 1.72 (SD 0.53). Cartilage regeneration of femur and tibia in Group A was observed in all patients. The cartilaginous thickness in Group A were significantly different (P < 0.001), such as the anterior patella femoral region 3.52 (SD 0.47), the anterior meniscal region 1.16 (SD 0.24), the posterior meniscal region 1.24 (SD 0.26) and the posterior condyle region 2.25 (SD 0.31). CONCLUSIONS The addition of combined PRP to HTO may be a more reasonable choice to relieve knee pain and decelerate the progression of the medial KOA.

Abstract
OBJECTIVE To analyze the effects of light therapy (LT) on cartilage repair for knee osteoarthritis (OA) treatment. DESIGN The PubMed, Embase, Scopus, and Web of Science databases were searched up to August 31, 2020 to identify in vitro and in vivo studies that analyzed the effects of LT on knee cartilage for OA treatment. The study and sample characteristics, LT intervention parameters and posttreatment outcomes were analyzed. Risk of bias was assessed using the Risk of Bias Assessment for Non-randomized Studies (RoBANS) tool. RESULTS Three in vitro and 30 in vivo studies were included. Most studies were judged as high risk of performance and detection bias. Biochemical outcomes were analyzed for both in vitro and in vivo studies, and histological and behavioral outcomes were analyzed for in vivo studies. LT reduced extracellular matrix (ECM) degradation, inflammation, and OA progression, promoting ECM synthesis. LT improved pain-like behavior in animal models, having no apparent effect on gait performance. There were conflicting findings of some of the biochemical, histological, and behavioral outcomes. CONCLUSION The included studies presented different strategies and LT parameters. LT resulted in positive effects on cartilage repair and may be an adequate therapy for OA treatment.

Photobiomodulation and Sida tuberculata combination declines the inflammation's markers in knee-induced osteoarthritis. Lasers Med Sci 2021; 37:193-204. [PMID: 33417067 DOI: 10.1007/s10103-020-03207-8] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/17/2020] [Accepted: 11/19/2020] [Indexed: 12/13/2022]
Abstract
The aim of this study was to assess potential combination effects of photobiomodulation therapy (PBMT) with Sida tuberculata extracts on the oxidative stress and antioxidant activity, as well as on the inflammatory process. Rats with knee osteoarthritis (OA) were treated with S. tuberculata extracts and PBMT (904 nm, 18 J/cm2). The animals were evaluated for nociception and edema. The blood, knee lavage and structures, spinal cord, and brainstem were collected for biochemical analyses (lipid peroxidation, protein carbonyl content, superoxide dismutase activity, non-protein thiol levels, and measurement of nitrite/nitrate). The knee structures were also used to measure cytokine levels. PBMT lowered the damage due to oxidative stress in the knee and at distant sites from the lesion. PBMT also reduced the levels of nitric oxide and cytokines, which could explain the nociception reduction mechanism. Similarly, S. tuberculata decreased the damage by oxidative stress, levels of nitrite/nitrate, and cytokines. The therapy combination reduced levels of cytokines and nitrite/nitrate. PBMT and S. tuberculata extracts reduced the oxidative stress and inflammation. It is noteworthy that PBMT increased the antioxidant activity in the knee and at sites distant from the lesion, contributing to a more significant decrease in nociception. The combination of therapies did not present significant effects on the analyzed parameters. Therefore, it is suggested that PBM is sufficient to minimize the signs and symptoms of the knee OA in our rat model.

Abstract
Knee osteoarthritis (OA) is a chronic disease that causes pain and gradual degeneration of the articular cartilage. In this study, MIA-induced OA knee model was used in rats to test the effects of the photobiomodulation therapy (PBM). We analyzed the inflammatory process (pain and cytokine levels), and its influence on the oxidative stress and antioxidant capacity. Knee OA was induced by monosodium iodoacetate (MIA) intra-articular injection (1.5 mg/50 μL) and the rats were treated with eight sessions of PBM 3 days/week (904 nm, 6 or 18 J/cm2 ). For each animal, mechanical and cold hyperalgesia and spontaneous pain were evaluated; biological analyses were performed in blood serum, intra-articular lavage, knee structures, spinal cord and brainstem. Cytokine assays were performed in knee, spinal cord and brainstem samples. The effects of the 18 J/cm2 dose of PBM were promising in reducing pain and neutrophil activity in knee samples, together with reducing oxidative stress damage in blood serum and spinal cord samples. PBM improved the antioxidant capacity in blood serum and brainstem, and decreased the knee pro-inflammatory cytokine levels. Our study demonstrated that PBM decreased oxidative damage, inflammation and pain. Therefore, this therapy could be an important tool in the treatment of knee OA.

Abstract
Background: Although chronic pain affects the quality of life of patients with osteoarthritis, current medical treatments are either ineffective or have long-term side effects. Recently, low-intensity laser irradiation of corresponding acupoints was demonstrated to alleviate pain. Objective: The aim of the present study was to investigate the effects of 10.6 μm laser moxibustion on a monosodium iodoacetate (MIA)-induced knee osteoarthritis pain model. Methods: Thirty-two rats were randomly assigned to four groups: Saline, MIA, MIA+Laser, and MIA+Sham Laser. The 10.6 μm laser was used to irradiate the ST35 for 10 min once a day for a total of seven applications. The paw withdrawal mechanical threshold and weight-bearing difference were performed to evaluate the analgesic effects of laser moxibustion. At the end of the experiment on days 28, the joint histology, the levels of metalloproteinases-13 (MMP-13) in the cartilage, and TNF-α, IL-1β, and IL-6 in the synovial membrane were measured to determine the chondroprotection and anti-inflammatory effect of laser moxibustion. Results: Early laser moxibustion significantly reversed the MIA-induced mechanical hyperalgesia and weight-bearing difference, especially on the 28th day (p < 0.001). Moreover, laser moxibustion prevented the articular pathological lesions and cartilage destruction on days 28 (p < 0.01). Remarkably, the levels of cartilage MMP-13, and synovial TNF-α, IL-1β, and IL-6 also decreased on day 28 (p < 0.05) after the early treatment of laser moxibustion. Conclusions: 10.6 μm laser moxibustion may have long-lasting analgesic, anti-inflammatory, and chondroprotection effects, suggesting that it may emerge as a potential therapeutic strategy for the chronic pain treatment of osteoarthritis.

Abstract
Background This study assessed the safety and efficacy of deep tissue laser therapy on the management of pain, functionality, systemic inflammation, and overall quality of life of older adults with painful diabetic peripheral neuropathy. Methods The effects of deep tissue laser therapy (DTLT) were assessed in a randomized, double-masked, sham-controlled, interventional trial. Forty participants were randomized (1:1) to receive either DTLT or sham laser therapy (SLT). In addition to the standard-of-care treatment, participants received either DTLT or SLT twice weekly for 4 weeks and then once weekly for 8 weeks (a 12-week intervention period). The two treatments were identical, except that laser emission was disabled during SLT. Assessments for pain, functionality, serum levels of inflammatory biomarkers, and quality of life (QOL) were performed at baseline and after the 12-week intervention period. The results from the two treatments were compared using ANOVA in a pre-test-post-test design. Results All participants randomized to the DTLT group and 85% (17 of 20) of participants randomized to the SLT group completed the trial. No significant differences in baseline characteristics between the groups were observed. After the 12-week intervention period, pain levels significantly decreased in both groups and were significantly lower in the DTLT group than in the SLT group. The Timed Up and Go test times (assessing functionality) were significantly improved in both groups and were 16% shorter in the DTLT group than in the SLT group. Serum levels of IL-6 decreased significantly in both groups. Additionally, serum levels of MCP-1 decreased significantly in the DTLT group but not in the SLT group. Patients’ quality of life improved significantly in the DTLT group but not in the SLT group. Conclusions Deep tissue laser therapy significantly reduced pain and improved the quality of life of older patients with painful diabetic peripheral neuropathy. Trial registration Clinical Trial Registry-India CTRI/2017/06/008739. [Registered on: 02/06/2017]. The trial was registered retrospectively.
