Prolotherapy in primary care practice

Efficacy of hypertonic dextrose proliferation therapy in the treatment of rotator cuff lesions: a meta-analysis

BACKGROUND

One of the most prevalent illnesses of the shoulder is rotator cuff tendinosis, which is also a major contributor to shoulder discomfort and shoulder joint dysfunction. According to statistics, rotator cuff tendinosis occurs in 0.3-5.5% of cases and affects 0.5-7.4% of people annually. It will be necessary to conduct a meta-analysis to evaluate the efficacy of hypertonic glucose proliferation therapy in the treatment of rotator cuff problems.

METHODS

The databases Cochrane PubMed, Library, Web of Science and EMbase, are retrieved by the computer. Individuals with rotator cuff lesions in the intervention group were treated with hypertonic dextrose proliferation therapy, whereas individuals in the control condition were treated with a placebo. Outcome markers for rotator cuff lesions patients; Pursuant to studies, the visual analogue scale (VAS) score, the shoulder pain & disability index (SPADI), & other metrics are used to evaluate the effects of hypertonic dextrose proliferation treatment on individuals with rotator cuff diseases. After carefully evaluating the calibre of the literature, data analysis was performed utilising the RevMan 5.3 programme.

RESULTS

Meta-analysis finally contained 6 papers. In six investigations, the test & control group's VAS scores improved, with the test team's score considerably outperforming the control team [standardized mean difference (SMD): 1.10; 95% Cl: 0.37,1.83; P < 0.01], shoulder pain and disability index (SPADI) score (SMD:8.13; 95% Cl: 5.34,10.91; P < 0.01), Flexion (SMD:5.73; 95% Cl: 0.99,10.47; P < 0.05), Abduction (SMD:6.49; 95% Cl: 0.66,12.31; P < 0.05), Internal rotation (SMD:-1.74; 95% Cl: -4.25,0.78; P = 0.176) and External rotation (SMD:2.78; 95% Cl: -0.13,5.69; P = 0.062).

CONCLUSION

The findings of this study suggest that individuals with rotator cuff injuries may benefit from hypertonic dextrose proliferation treatment based on the visual analogue scale (VAS) score, the Shoulder Pain and Disability Index (SPADI) score, Flexion, & Abduction. These results must, nevertheless, be supported by high-caliber follow-up research.

Comparison Clinical Effects of Hypertonic Dextrose and Steroid Injections on Chronic Subacromial Bursitis: A Double-Blind Randomized Controlled Trial

OBJECTIVE

The aim of the study is to determine and compare the treatment efficacy of subacromial steroid injections and dextrose prolotherapy for chronic subacromial bursitis patients.

DESIGN

Fifty-four patients with chronic subacromial bursitis were enrolled in this double-blind randomized controlled trial. Shoulder Pain and Disability Index and visual analog scale were the primary outcomes.

RESULTS

The steroid group ( n = 26) exhibited significant visual analog scale score improvements comparing with baseline at weeks 2, 6, and 12; the dextrose prolotherapy group ( n = 28) exhibited visual analog scale score improvements at weeks 6 and 12. The steroid group displayed significant Shoulder Pain and Disability Index score improvements compared with baseline at weeks 2, 6, and 12; the dextrose prolotherapy group exhibited significant score decreases at weeks 2 and 6. Compared with the dextrose prolotherapy group, the steroid group demonstrated significantly greater decreases in visual analog scale scores at weeks 2 and 6; the steroid group showed significantly greater decreases in Shoulder Pain and Disability Index scores at weeks 2, 6, and 12.

CONCLUSIONS

Both hypertonic dextrose prolotherapy and steroid injections can provide short-term improvements of pain and disability among chronic subacromial bursitis patients. Moreover, steroid injections showed better effectiveness than hypertonic dextrose prolotherapy in ameliorating pain and improving function.

Infraspinatus Fascial Dysfunction as a Cause of Painful Anterior Shoulder Snapping: Its Visualization via Dynamic Ultrasound and Its Resolution via Diagnostic Ultrasound-Guided Injection

This report presents the first case of painful anterior shoulder snapping due to a thickened, fibrotic bursa snapping between the subscapularis and the short head of the bicep during external and internal rotation of the humerus. A 46-year-old presented with a 10-month history of on-and-off anterolateral right shoulder pain and snapping. Direct treatment to the anterior suspected lesions partially and temporarily relieved the pain but did not reduce the snapping. Further musculoskeletal examination and dynamic ultrasound scanning showed dysfunction in the scapulothoracic movement and defects of the muscles that interact with the infraspinatus aponeurotic fascia. An ultrasound-guided diagnostic injection to the suspected lesions in the infraspinatus fascia and its muscles attachments improved the scapulothoracic movement, and the snapping and pain were eliminated immediately after the injection, which further shows that the defects in the infraspinatus fascia may be the root cause of the painful anterolateral snapping. The importance of the infraspinatus fascia and its related muscle in maintaining the harmony of the scapulothoracic movement and flexibility of the shoulder is considerable.

Is dextrose prolotherapy beneficial in the management of temporomandibular joint internal derangement? A systematic review

OBJECTIVE

To highlight the current knowledge of the efficacy of dextrose as a prolotherapy agent in managing temporomandibular joint internal derangement (TMJ-ID).

METHODS

A "Population, Intervention, Comparison, Outcome" (PICO) strategy was executed using an electronic search through PubMed/MEDLINE, Cochrane databases, and Google Scholar from their inception to August 2022. Only randomized clinical trials investigating the treatment of TMJ-ID with hypertonic dextrose prolotherapy (HDPT) were included. Two independent reviewers assessed the eligibility of the studies with subsequent data extraction.

RESULTS

The systematic search identified 392 studies, and only 8 articles were considered eligible for selection, with a total of 286 patients; 72% were females, and 28% were males. The extracted data showed positive effects of dextrose on joint pain and maximum mouth opening (MMO) with high patient satisfaction.

CONCLUSION

HDPT can be effective in relieving TMD symptoms as it reduces pain, improves joint dysfunction, and increases MMO up to 12 months.

Efficacy of Prolotherapy for Osteoarthritis: A Systematic Review

OBJECTIVE

Current treatments for osteoarthritis do not resolve the underlying cause. Dextrose prolotherapy is an alternative method that has been proposed for treatment of osteoarthritis, due to its ability to aid tissue regeneration, improve clinical manifestations, and repair damaged tissue structures, which are pathological conditions in osteoarthritis. The aim of this systematic review was to evaluate the efficacy of dextrose prolotherapy compared with other interventions in the management of osteoarthritis.

METHODS

Electronic databases PubMed, Google Scholar, Cochrane, and BioMed Central were searched from inception to October 2021. Search terms included [(prolotherapy) OR (prolotherapies) OR (dextrose prolotherapy)] AND [(osteoarthritis) OR (osteoarthritides) OR (knee osteoarthritis) OR (hip osteoarthritis) OR (hand osteoarthritis) OR (shoulder osteoarthritis)]. Randomized controlled trials that compared the use of dextrose prolotherapy with other interventions (injection, placebo, therapy, or conservative treatment) in the treatment of osteoarthritis were included. Potential articles were screened for eligibility, and data were extracted by all authors. Risk of bias was assessed using the Cochrane Risk of Bias tool. Study population, methods, and results data were extracted and tabulated by 3 authors.

RESULTS

12 studies reported that DPT was as effective or even more effective in improving functional outcomes compared with other interventions whilst others found that HA, PRP, EP, and ACS were more effective. 14 studies assessed the effectiveness of DPT and ten of them reported that DPT was more effective in reducing pain compared with other interventions.

CONCLUSION

Dextrose prolotherapy in osteoarthritis confers potential benefits for pain and functional outcomes, but this systematic review found that the studies to date are at high risk of bias.

Regenerative medicine for the treatment of chronic low back pain: a narrative review

Low back pain (LBP) is a common and important clinical problem. In addition to pain, patients are also affected by personal, social, and economic burdens. Intervertebral disc (IVD) degeneration is a common cause of LBP, further increasing the patient's morbidity and medical costs. The limitations of current treatment strategies for long-term pain relief mean that increasing attention has been paid to regenerative medicine. We carried out a narrative review to explore the roles of four types of regenerative medicine for treating LBP: marrow-derived stem cells, growth factors, platelet-rich plasma, and prolotherapy. Marrow-derived stem cells are regarded as an ideal cell source for IVD regeneration. Growth factors may stimulate the synthesis of extracellular matrix and attenuate or reverse the degenerative process in IVD, while platelet-rich plasma, which contains multiple growth factors, is thought to be a promising alternative therapy for IVD degeneration. Prolotherapy can initiate the body's inflammatory healing response to repair injured joints and connective tissues. This review summarizes the mechanisms, in vitro and in vivo studies, and clinical applications of these four types of regenerative medicine in patients with LBP.

The effect of dextrose prolotherapy versus placebo/other non-surgical treatments on pain in chronic plantar fasciitis: a systematic review and meta-analysis of clinical trials

BACKGROUND

Prolotherapy is the injection of a small volume of sclerosing or irritant solutions into an injured tissue. We aimed to investigate the effect of dextrose prolotherapy (DPT) versus placebo/other non-surgical treatments on pain in chronic plantar fasciitis.

METHODS

We searched seven electronic databases (PubMed/MEDLINE, Web of Science, EMBASE, Scopus, ProQuest, CENTRAL, PEDro) from inception to December 31, 2021 with no language restriction for publications comparing the effect of DPT with placebo/other non-surgical treatments in patients with chronic plantar fasciitis. Our primary outcome was pain and the secondary outcomes were foot function and plantar fascia thickness. The risk of bias was assessed using the Cochrane Collaboration's tool.

RESULTS

Overall, eight studies with a total of 449 patients were included in the meta-analysis. All the included studies reported short-term pain. A large effect size (dppc2 = -0.97, 95% confidence interval [CI] -1.84 to -0.10) was observed favoring the use of DPT to reduce pain in patients with chronic plantar fasciitis in the short-term. The results for foot function improvement (dppc2 = -1.28, 95% CI -2.49 to -0.07) and plantar fascia thickness reduction (dppc2 = -1.02, 95% CI -1.99 to -0.05) in the short-term were also in favor of DPT.

CONCLUSIONS

Since almost all the included studies had high risk of bias and multiple trials lacked long-term follow-ups, further high-quality research is required to determine the long-term effects of DPT vs placebo/other non-surgical interventions.

Is Low-Dose Dextrose Prolotherapy as Effective as High-Dose Dextrose Prolotherapy in the Treatment of Lateral Epicondylitis? A Double-Blind, Ultrasound Guided, Randomized Controlled Study

OBJECTIVES

To investigate the effects of prolotherapy (PrT) on pain, functionality, clinical improvement and to compare the 5% low and 15% high dose dextrose PrT in chronic lateral epicondylitis.

DESIGN

A double-blind, parallel groups, randomized controlled study.

SETTINGS

Outpatient Clinic.

PARTICIPANTS

Sixty patients (N=60), aged 44.30±10.31 years old, with chronic lateral epicondylitis were allocated randomly into 3 groups.

INTERVENTIONS

To Group 1 5% dextrose PrT, to Group 2 15% dextrose PrT, to Group 3 0.9% saline injections were done at 3 times (weeks 0, 3, 6), to the entheses of forearm extensors and annular ligament.

MAIN OUTCOME MEASURES

The primary outcomes were handgrip strength, visual analog scale-rest (VAS-R), visual analog scale-activity (VAS-A), pressure-pain threshold, and Quick Disability of the Arm, Shoulder and Hand (Q-DASH). The secondary outcomes were clinical improvement (Disease Global Assessment Questionnaire), side effects, and complications. Primary outcomes were collected at baseline week 0, week 3, and 12. Secondary outcomes were collected at weeks 3 and 12.

RESULTS

In Group 2, VAS-A and VAS-R (at week 3), handgrip strength and pressure-pain threshold (at week 12) were significantly different than other groups (P<.05). In Groups 1 and 2, there was a difference in primary outcomes at week 12 than baseline (P<.05). In Group 3, there was no difference in VAS-R, VAS-A, and handgrip strength at weeks 3 and 12 than baseline (P>.05).

CONCLUSION

In chronic lateral epicondylitis, 5% and 15% dextrose PrT is more effective in pain, handgrip strength, functionality, and clinical improvement than %0.9 saline. There was no difference in functionality, clinical improvement, side effects, and complications between the PrT groups. 15% dextrose PrT was more effective in handgrip strength and pressure-pain threshold at week 12 and pain at week 3. We recommend 15% dextrose PrT based on this study.

Demonstrating the effectiveness of Platelet Rich Plasma and Prolotherapy treatments in knee osteoarthritis

BACKGROUND

Platelet-rich plasma(PRP) and prolotherapy(PRL) are regenerative treatment approaches in the knee osteoarthritis (KOA).

AIM

To see how efficient PRP and PRL are in treating KOA.

METHODS

A total of 108 patients with a diagnosis of KOA who received either PRL, PRP, or exercise therapy and whose 3-month follow-up data were available were included in this retrospective study (PRL n = 35 or PRP n = 35, exercise n = 38). Visual Analogue Scale(VAS) and The Western Ontario McMaster University Osteoarthritis Index(WOMAC) were used as outcome measures at baseline, 1 month, and 3 months.

RESULTS

There were no statistically significant differences between the three groups in terms of demographic parameters, baseline assessments of pain intensity, or WOMAC scores. At the first and third months, all groups showed a substantial improvement in the VAS activity, resting and WOMAC values as compared to before treatment(p < 0.05). When the groups were compared, the VAS activity, resting, and WOMAC values in PRP and PRL improved significantly in the first and third months compared to the exercise group. At one month, there was a statistically significant improvement in VAS activity and WOMAC pain and total scores compared to PRP and PRL, but this improvement was not significant at 3 months.

CONCLUSION

Pain and disability were significantly improved with PRL and PRP compared with exercise therapy. Although PRP is more effective than PRL in the first month after treatment, PRL may be preferred due to its low cost, long-term efficacy, and low complication rates due to the periarticular application.

Ultrasound-Guided Injection of Dextrose Versus Corticosteroid in Chronic Plantar Fasciitis Management: A Randomized, Double-Blind Clinical Trial

DESIGN

Chronic plantar fasciitis (PF) is a common cause of chronic heel pain, with different conventional treatment options. In this randomized clinical trial, the effect of ultrasound-guided injection of dextrose versus corticosteroid in chronic PF was evaluated and compared.

METHODS

A total of 44 patients suffering from chronic PF who visited the physical medicine and rehabilitation clinic were enrolled in the study. Two table-randomized groups were formed. They received an ultrasonography-guided, single injection of either 40 mg methylprednisolone or 20% dextrose. Numeric Rating Scale (NRS), Foot and Ankle Ability Measure questionnaire with 2 subscales, Activities of Daily Living (FAAM-A) and Sports (FAAM-S), along with ultrasonographic parameters were evaluated before and at 2 and 12 weeks after the injection. Results. A total of 40 participants completed the study. Both interventions significantly improved pain and function at 2 and 12 weeks postinjection. After 2 weeks, compared with the dextrose prolotherapy, the corticosteroid group had significantly lower daytime and morning NRS scores (2.55 vs 4.1, P = .012, and 2.75 vs 4.65, P = .004), higher FAAM-S (66.84 vs 54.19; P = .047), and lower plantar fascia thickness at insertion and 1 cm distal to the insertion zone (3.89 vs 4.29 mm, P = .004, and 3.13 vs 3.48 mm, P = .002), whereas FAAM-A was similar in both groups (P = .219). After 12 weeks, all study variables were statistically similar between corticosteroid and dextrose prolotherapy groups. No injection-related side effects were recorded in either group.

CONCLUSION

Both methods are effective. Compared with dextrose prolotherapy, our results show that corticosteroid injection may have superior therapeutic effects early after injection, accompanied by a similar outcome at 12 weeks postinjection.

Efficacy comparison between ultrasound-guided injections of 5% dextrose with corticosteroids in carpal tunnel syndrome patients

BACKGROUND

There is no standard guideline for treating mild to moderate carpal tunnel syndrome (CTS). 5% dextrose perineural injection has been a potential and innovative treatment with long-term effects for CTS; however, there is few published randomized clinical trial comparing the efficacy of 5% dextrose perineural injection versus corticosteroid injection in treating CTS.

MATERIALS AND METHODS

In this double-blinded randomized active-controlled trial, we randomly allocated 1 session of either 2 cc 5% dextrose or 1 cc methylprednisolone acetate mixed with 1 cc normal saline in 36 patients with mild to moderate CTS of single or both their wrists. The baseline VAS, BCTQ, electrophysiological studies, and sonography assessment of median nerve CSA were carried out at the baseline and 1-month and 3-month follow-ups, as well as recording demographic variables.

RESULTS

A statistically significant decreasing trend in VAS (P < 0.0001), BCTQ-ss (P < 0.0001), median nerve CSA (P = 0.05), SNAP-PL (P < 0.0001), and CMAP-OL (P = 0.048) in both methylprednisolone and 5% dextrose groups was observed. No significant difference was observed in slope of the trend of studied parameters, including VAS (P = 0.95), BCTQ-ss (P = 0.88), BCTQ-F (P = 0.34), median nerve CSA (P = 0.321), SNAP-PL (P = 0.9), CMAP-OL (P = 0.799), SNAP-amplitude (P = 0.798), and CMAP-amplitude (P = 0.584).

CONCLUSION

5% dextrose perineural injection is an effective and safe treatment for mild to moderate CTS, in comparison with the short-term results attained from corticosteroids. Further randomized clinical trials with longer follow-up periods are warranted.

A comprehensive review of intraarticular knee injection therapy, geniculate injections, and peripheral nerve stimulation for knee pain in clinical practice

The knee is the most common joint in adults associated with morbidity. Many pathologies are associated with knee damage, such as gout or rheumathoid arthritis, but the primary condition is osteoarthritis (OA). Not only can osteoarthritis cause significant pain, but it also can result in signficant disability as well. Treatment for this condition varies, starting off with oral analgesics and physical therapy to surgical total knee replacmenet. In the gamut of this various treatments, a conservative approach has included intra articular steroid injections. With time, researchers and clinicians determined that other components injected to the knee may additionally provide relief of this condition. In this investigation, we describe different types of knee injections such as platelet-rich plasma (PRP), hyaluronic acid, stem cells, and prolotherapy. Additionally, we describe the role of geniculate knee injections, radiofrequency, and periopheral nerve stimulation. These treatments should be considered for patients with knee pain refractory to conservative therapies.

Hyperosmolar dextrose injection for Osgood-Schlatter disease: a double-blind, randomized controlled trial

OBJECTIVE

Osgood-Schlatter disease (OSD) is one of the common causes of long-term knee pain, leading to functional limitations, long-term deformity of the tubercle interfering with kneeling, and impaired peer-important sport participation. Nonetheless, patient management continues to rely on the usual conservative methods. This study examined the use of hyperosmolar dextrose injection in patients with OSD.

METHODS

We conducted a randomized, double-blind clinical trial involving 70 patients with OSD. One group received a hyperosmolar dextrose injection (12.5%), while the other received a saline injection. The injections were conducted under ultrasound guidance. The Victorian Institute of Sport Assessment (VISA) score was used to assess each patient's pain and sport level.

RESULTS

The dextrose group outperformed the saline group in improvement in the VISA-Patella (VISA-P) score from baseline to 3 months (27.1 ± 6.5 vs. 1.4 ± 2.6; mean difference 25.4 (22.4 to 28.3); p < .0001), 6 months (31.7 ± 7.9 vs. 25.2 ± 7.8; mean difference 6.2 (3.2 to 9.4); p < .0001), and 12 months (34 ± 9.0 vs. 28.2 ± 7.5; mean difference 5.5 (1.9 to 9.1); p = .0026). The changes in both groups were clinically important, suggesting that both therapies were active treatments. The dextrose group improved too rapidly for spontaneous improvement to explain much of this change.

CONCLUSION

After three injections, at the 6-month and 12-month follow-up visits, the VISA-P scores of the two groups were significantly improved; the dextrose group score was better than the saline group score, and there were significant differences between the two groups.

Ultrasound-guided 5% dextrose prolotherapy versus corticosteroid injection in carpal tunnel syndrome: a randomized, controlled clinical trial

Aim: The main assessment of this study is to analyze the efficiency of ultrasound-guided dextrose prolotherapy against corticosteroid injections for the treatment of carpal tunnel syndrome. Materials & methods: A total of 54 patients with carpal tunnel syndrome were included. Patients who were assigned into the prolotherapy group were injected with 5cc 5% dextrose water under ultrasound guidance. Patients in the corticosteroid group received ultrasound-guided 1 ml triamcinolone 40 mg/ml injection. Results: The inter-group analysis revealed that dextrose prolotherapy has a similar efficacy as corticosteroid for improving pain intensity, functional limitation in daily life, electrophysiologic parameters and ultrasonographic outcomes. No remarkable difference was found between the two treatments until 3 months of follow-up. Conclusion: Dextrose 5% has similar efficacy as triamcinolone for improving pain intensity, functional limitation in daily life, electrophysiologic parameters and ultrasonographic outcomes.

A Comprehensive Update of Prolotherapy in the Management of Osteoarthritis of the Knee

This is a comprehensive review of the literature focusing on the use of prolotherapy in the treatment of osteoarthritis of the knee. It covers the background, efficacy, and advantages of prolotherapy in the management of osteoarthritis symptoms and then covers the existing evidence of the use of prolotherapy for this purpose. Current treatments for osteoarthritis of the knee are numerous, yet patients continue to endorse chronic pain and poor quality of life. Prolotherapy is a treatment that has been inadequately studied with poor sample sizes and lack of standardization between trials. However, in recent years the literature on prolotherapy in the treatment of knee osteoarthritis has grown. Although there is still a lack of homogeneity, trials have shown that dextrose prolotherapy, autologous conditioned serum, hyaluronic injections, and normal saline administered either intra- or peri-articularly are comparable in reducing pain scores to other primary treatment options. The mechanism of action for prolotherapy is still unclear, but researchers have found that prolotherapy plays some role in cartilage growth or chondrogenesis and has been shown to have improved radiographic outcomes. Prolotherapy appears to be a safe treatment alternative that has been shown to improve stiffness, pain, function, and quality of life in osteoarthritis of the knee. Knee osteoarthritis is remarkably prevalent in the United States and is one of the most common causes of disability in the elderly population. Although there are many treatment options, patients continue to live with chronic pain which can incur high costs for patients. A safe, long-term, and effective solution has not yet been identified. Prolotherapy has been shown to be a safe option for improving pain, function, and quality of life as effectively as other treatment options.

Meta-analysis of clinical trials focusing on hypertonic dextrose prolotherapy (HDP) for knee osteoarthritis

Hypertonic dextrose prolotherapy (HDP) is an injection of a concentrated dextrose solution for the purpose of local treatment of musculoskeletal pain and possible enhancement of repair mechanisms. This systematic review and meta-analysis examines the clinical utility of HDP injection for treatment of knee osteoarthritis (OA). Randomized controlled trials (RCTs) utilizing HDP to treat knee OA were retrieved from MEDLINE, EMBASE, and Cochrane Library (CENTRAL). Identification and inclusion of RCTs utilizing intra-articular and extra-articular administration of HDP vs administration of other injectate or physical therapy as control for knee OA were included. Primary clinical outcomes were changes in knee WOMAC, pain and function score. Secondary outcomes were adverse events related to HDP. For continuous outcomes with same or different measurements, we calculated, respectively the weighted mean difference (WMD) or the standardized mean difference (SMD), respectively. Results were pooled using DerSimonian and Laird random effect models across the included studies and heterogeneity between studies was estimated using the I² index. Five studies comprising a total of 319 treated patients met inclusion criteria and were included in the final analysis. At a mean of 22.8 weeks follow-up, HDP treatment significantly improved total WOMAC score (WMD = 13.77, 95% CI: 6.75-20.78; p < 0.001; I² = 90%), pain (SMD = 1.33, 95% CI: 0.49-2.17; p < 0.001; I² = 91%) and knee function (SMD = 1.30, 95% CI: 0.45-2.14; p < 0.001; I² = 91%) compared with control group. There were no severe adverse events related to dextrose injection reported in all the included studies. HDP is a promising treatment for knee OA with a reasonable safety profile. Further research in mechanism of HDP activity and long-term follow-up study will be needed for exploring this novel therapy modality.

Identification of early response to hypertonic dextrose prolotherapy markers in knee osteoarthritis patients by an inflammation-related cytokine array

BACKGROUND

Osteoarthritis (OA) is one of the most common forms of arthritis, and hypertonic dextrose prolotherapy has long been used clinically to treat knee OA. The aim of this study was to investigate the inflammation-related protein-expression profile characterizing the efficacy of the hypertonic dextrose prolotherapy in knee OA as prognostic markers.

METHODS

OA patients over the age of 65 were recruited for Western Ontario McMaster University Osteoarthritis (WOMAC) index, knee X-ray evaluation and knee joint synovial fluid analysis before and after hypertonic dextrose prolotherapy. The expressions of inflammation-related factors were measured using a novel cytokine antibody array methodology. The cytokine levels were quantified by quantitative protein expression and analyzed by ELISA using the patients' knee-joint synovial fluid.

RESULTS

The WOMAC Index and minimum joint space width before receiving the intra-articular injection and at 2-week intervals were compared. Twelve patients who received OA intervention were enrolled and finally a clinical evaluation of 12 knee joints and knee synovial fluid samples were analyzed. In this study, after receiving hypertonic dextrose prolotherapy, the OA patients clearly demonstrated a significant improvement in WOMAC index and increasing tendency in the medial minimum joint space width after intervention. Meanwhile, we observed a significantly associated tendency between hypertonic dextrose treatment of knee OA and the upregulation of MMP2, TIMP-1, EGF, CXCL9 and IL-22.

CONCLUSION

The findings provide knee OA patients receiving hypertonic dextrose prolotherapy, which is accompained by the improvemeny of knee symptoms and associated tendency of upregulation of MMP2, EGF, CXCL 9 and IL-22.

Diagnosis, Treatment, and Management of Painful Scar: A Narrative Review

Painful scars can develop after surgery or trauma, with symptoms ranging from a minor itch to intractable allodynia. The problem of the painful scar may involve both intraneural and extraneural structures, requiring a systematic approach to diagnosis and treatment of this neuropathic pain condition that can impact quality of life and function profoundly. In this review, we outline the algorithm for the diagnosis, management, medical and surgical treatment of painful scars.

Effectiveness, Compliance, and Safety of Dextrose Prolotherapy for Knee Osteoarthritis: A Meta-Analysis and Metaregression of Randomized Controlled Trials

OBJECTIVES

This study assessed the effectiveness, compliance, and safety of dextrose prolotherapy for patients with knee osteoarthritis.

DATA SOURCES

PubMed, EMBASE, the Cochrane Library Database, and the Scopus database from their inception to December 31, 2021.

METHODS

This study was conducted in accordance with the guidelines recommended by the Preferred Reporting Items for Systematic Reviews and Meta-Analysis. Randomized controlled trials regarding the effectiveness of dextrose prolotherapy in knee osteoarthritis were identified. The included trials were subjected to meta-analysis. Risk of bias was assessed using the Cochrane risk of bias tool. Subgroup and random-effects metaregression analyses were performed to explore any heterogeneity (I²) of treatment effects across studies.

RESULTS

A total of 14 trials enrolling 978 patients were included in the meta-analysis. Compared with placebo injection and noninvasive control therapy, dextrose prolotherapy had favorable effects on pain, global function, and quality of life during the overall follow-up. Dextrose prolotherapy yielded greater reductions in pain score over each follow-up duration than did the placebo. Compared with other invasive therapies, dextrose prolotherapy generally achieved comparable effects on pain and functional outcomes for each follow-up duration.Subgroup results indicated that combined intra-articular and extra-articular injection techniques may have stronger effects on pain than a single intra-articular technique.

CONCLUSIONS

Dextrose prolotherapy may have dose-dependent and time-dependent effects on pain reduction and function recovery, respectively, in patients with knee osteoarthritis. Due to remarkable heterogeneity and the risk of biases across the included trials, the study results should be cautiously interpreted.

The effects of inclusion of minimal-dose corticosteroid in autologous whole blood and dextrose injection for the treatment of lateral epicondylitis

BACKGOUND

Lateral epicondylitis (LE) is one of the most common musculoskeletal disorders that causes pain.

OBJECTIVES

We evaluated the effect of the inclusion of a minimal dose of corticosteroid in a solution comprising autologous whole blood (AWB), 20% dextrose, and 2% lidocaine for treating LE.

METHODS

In this randomized prospective trial LE patients were allocated to the CS+ group (n= 70; solution comprising 1 mL AWB, 1 mL 20% dextrose, 0.4 mL 2% lidocaine, and 0.1 mL (0.4 mg) dexamethasone palmitate; injected into the common wrist extensor tendon) or the CS- group (n= 70; same solution as above but without dexamethasone palmitate). Five injections were administered at monthly intervals. At each visit, pain intensity was evaluated using the numeric rating scale (NRS), and grip strength was measured using a hand-grip dynamometer.

RESULTS

In the CS+ and CS- groups, 1 and 10 patients dropped out, respectively. In both groups, the NRS scores at each evaluation were significantly lower than the pretreatment scores. The NRS scores from pretreatment to the second and third visits were significantly lower in the CS+ group than those in the CS- group. However, at the fourth and fifth visits, and 6 months after the last injection (the sixth visit), the degree of pain reduction between the groups was not significantly different. Grip strength increased significantly over time in both groups. At each evaluation, grip strength was significantly higher than that at the pretreatment stage. However, the degree of increase was not significantly different between groups.

CONCLUSIONS

The inclusion of a minimal dose of corticosteroid in the AWB and 20% dextrose injection can reduce pain, especially during early treatment.

Comparison of Ultrasound-Guided Prolotherapy Versus Extracorporeal Shock Wave Therapy in the Treatment of Chronic Plantar Fasciitis: A Randomized Clinical Trial

This study aimed to compare the effectiveness of extracorporeal shockwave therapy (ESWT) versus dextrose prolotherapy on pain and foot functions in patients with chronic plantar fasciitis with a prospective randomized-controlled trial. A total of 29 patients in whom conservative care failed were enrolled for the study after the clinical and ultrasonographic assessment. The patients were randomly assigned to receive ESWT (ESWT group, n = 15) or dextrose prolotherapy (dextrose prolotherapy group, n = 14). ESWT group received 1800 to 2000 focused shock waves (session of 0.20-0.30 mJ/mm² with a frequency of 4-6 Hz) followed by soft tissue 3000 to 3500 radial pulses (session of 1.8-3.0 bar with a frequency of 15-21 Hz). Dextrose prolotherapy group underwent an injection of 5 ml 15% dextrose solution with 2% lidocaine. ESWT and dextrose prolotherapy were repeated 3 times by 2 weeks apart. A 100-mm Visual Analog Scale (VAS) for overall and morning pain, Foot Function Index (FFI) and the Roles and Maudsley Scale score (RMS) were assessed at baseline, 6 weeks, and 12 weeks after the last intervention. Overall VAS, Morning VAS, RMS and FFI scores improved significantly in both treatment groups at 6 weeks and 12 weeks compared to baseline (p < .001). Comparison of changes in overall VAS, Morning VAS, RMS and FFI scores did not show a significant difference between the groups at each time point (p > .05) In our study dextrose prolotherapy and ESWT had similar effectiveness in patients with chronic plantar fasciitis who have not respond to conservative care. The results showed ESWT and dextrose prolotherapy were not superior to each other.

Hypertonic Dextrose Stimulates Chondrogenic Cells to Deposit Collagen and Proliferate

OBJECTIVE

Hypertonic dextrose (HD) injections (prolotherapy) for osteoarthritis are reported to reduce pain. Cartilage regeneration is hypothesized as a mechanism. This in vitro study identifies an HD concentration that stimulates chondrogenic cells to increase metabolic activity and assesses whether this concentration affects collagen deposition and proliferation.

DESIGN

ATDC5 chondrogenic cells were cultured in normoglycemic DMEM/F12 medium, treated with concentrations of HD (4-400 mM), and assessed with PrestoBlue. Advanced light microscopy was used to conduct live imaging of collagen deposition through second harmonic generation microscopy (SHG) and proliferation via 2-photon excitation microscopy. Proliferation was additionally assessed with hemocytometer counts.

RESULTS

A linear regression model found that, relative to the 4 mM baseline control, cells treated with 200 mM had a higher mean absorbance (P = 0.023) and cells treated with 250 mM were trending toward a higher mean absorbance (P = 0.076). Polynomial regression interpolated 240 mM as producing the highest average absorbance. Hemocytometer counts validated 250 mM as stimulating proliferation compared with the 4 mM control (P < 0.01). A concentration of 250 mM HD led to an increase in collagen deposition compared with that observed in control (P < 0.05). This HD concentration also led to increases in proliferation of ATDC5 cells relative to that of control (P < 0.001).

CONCLUSIONS

A 250 mM HD solution appears to be associated with increased metabolic activity of chondrocytes, increased collagen deposition, and increased chondrocyte proliferation. These results support clinical prolotherapy research suggesting that intra-articular HD joint injections reduce knee pain. Further study of HD and cellular processes is warranted.

Effect of Hypertonic Dextrose Injection on Pain and Shoulder Disability in Patients with Chronic Supraspinatus Tendinosis: A Randomized Double-Blind Controlled Study

OBJECTIVES

To investigate the effect of hypertonic dextrose injection on pain and disability in patients with chronic supraspinatus tendinosis. The secondary aim was to evaluate its effect on the tendon range of motion (ROM) and morphology.

DESIGN

Randomized double-blind placebo-controlled trial.

SETTING

Outpatient clinic.

PARTICIPANTS

Individuals (N=57) with symptomatic chronic supraspinatus tendinosis.

INTERVENTIONS

Participants were randomly administered ultrasound-guided injections of 20% hypertonic dextrose (study group, n=29) or 5% normal saline (control group, n=28).

MAIN OUTCOME MEASURES

The primary outcome measure was visual analog scale (VAS) scores for pain and Shoulder Pain and Disability Index (SPADI) scores. Secondary outcomes included the ROM and ultrasound examination findings of the supraspinatus tendon at baseline and at 2, 6, and 12 weeks postintervention.

RESULTS

The study group exhibited significant improvements in the VAS (mean difference [MD], -2.1; 95% confidence interval [CI], -2.7 to -1.4; P<.001) and SPADI (MD, -11.6; 95% CI, -16.5 to -6.7; P<.001) scores compared with baseline scores at week 2. However, the effect was not sustained to week 6. Flexion ROM increased at weeks 2 (MD, 14.1; 95% CI, 5.7-22.5; P<.001) and 6 (MD, 8.9; 95% CI, 2.4-15.4; P=.003) compared with baseline. The thickness of the supraspinatus tendon improved at weeks 6 (MD, .50; 95% CI, .26-.74; P<.001) and 12 (MD, .61; 95% CI, .37-.84; P<.001) compared with baseline. The ratio of histograms also improved at weeks 6 (MD, .19; 95% CI, .06-.32; P=.002) and 12 (MD, .26; 95% CI, .10-.41; P<.001) compared with baseline.

CONCLUSION

Hypertonic dextrose injection could provide short-term pain and disability relief in patients with chronic supraspinatus tendinosis. Ultrasound imaging at week 6 revealed changed tendon morphology.

Dextrose prolotherapy versus radial extracorporeal shock wave therapy in the treatment of chronic plantar fasciitis: A randomized, controlled clinical trial

In the recent years, prolotherapy is increasingly being used in the field of musculoskeletal medicine. However, few studies have investigated its effectiveness in plantar fasciitis (PF). The purpose of this study was to compare the effectiveness of ultrasound-guided dextrose prolotherapy with radial extracorporeal shock wave therapy (ESWT) in the treatment of chronic PF. This randomized controlled trial was conducted on 59 patients with chronic PF. Patients were randomly assigned into two groups receiving three sessions of radial ESWT (29 patients) vs. two sessions of ultrasound-guided intrafascial 2 cc dextrose 20% injection (30 patients). The following outcome measures were assessed before and then six weeks and 12 weeks after the treatments: pain intensity by visual analog scale (VAS), daily life and exercise activities by Foot and Ankle Ability Measure (FAAM), and the plantar fascia thickness by ultrasonographic imaging. The VAS and FAAM scales showed significant improvements of pain and function in both study groups 6 weeks and 12 weeks after the treatments. A significant reduction was noted for plantar fascia thickness at these intervals (all p < .05). The inter-group comparison revealed that except for the FAAM-sport subscale which favored ESWT, the interaction effects of group and time were not significant for other outcome measures. Dextrose prolotherapy has comparable efficacy to radial ESWT in reducing pain, daily-life functional limitation, and plantar fascia thickness in patients with PF. No serious adverse effects were observed in either group. LEVEL OF EVIDENCE: Level I, randomized controlled trial.

Dextrose prolotherapy in knee osteoarthritis: A systematic review and meta-analysis

OBJECTIVE

To summarize the evidence for dextrose prolotherapy in knee osteoarthritis.

DATA SOURCES

The authors searched PubMed and Embase from inception to September 2020. All publications in the English language were included without demographic limits.

STUDY SELECTION

Randomized clinical trials comparing the effects of any active interventions or placebo versus dextrose prolotherapy in patients with knee osteoarthritis were included.

DATA EXTRACTION

Potential articles were screened for eligibility, and data was extracted independently. The risk of bias was assessed using the Cochrane Risk of Bias tool. Meta-analysis was performed on clinical trials with similar parameters. The Strength of Recommendation Taxonomy (SORT) was used for evaluating the strength of recommendations.

DATA SYNTHESIS

In total, eleven articles (n = 837 patients) met the search criteria and were included. The risk-of-bias analysis revealed two studies to be of low risk. The overall effectiveness was calculated using a meta-analysis method. Prolotherapy was no different from platelet-rich plasma on the pain subscale at the 6-month time point. Prolotherapy was inferior to platelet-rich plasma at 6 months (MD 0.45, 95% CI 0.06-0.85, p = 0.03) on the stiffness subscale. Prolotherapy was found to be safe with no major adverse effects.

CONCLUSION

Prolotherapy in knee osteoarthritis confers potential benefits for pain but the studies are at high risk of bias. Based on two well-designed studies, dextrose prolotherapy may be considered in knee osteoarthritis (strength of recommendation B). This treatment is safe and may be considered in patients with limited alternative options (strength of recommendation C).

Invasive Treatments for Low Back Disorders

OBJECTIVE

This abbreviated version of the American College of Occupational and Environmental Medicine's Low Back Disorders guideline reviews the evidence and recommendations developed for invasive treatments used to manage low back disorders.

METHODS

Comprehensive systematic literature reviews were accomplished with article abstraction, critiquing, grading, evidence table compilation, and guideline finalization by a multidisciplinary expert panel and extensive peer-review to develop evidence-based guidance. Consensus recommendations were formulated when evidence was lacking and often relied on analogy to other disorders for which evidence exists. A total of 47 high-quality and 321 moderate-quality trials were identified for invasive management of low back disorders.

RESULTS

Guidance has been developed for the invasive management of acute, subacute, and chronic low back disorders and rehabilitation. This includes 49 specific recommendations.

CONCLUSION

Quality evidence should guide invasive treatment for all phases of managing low back disorders.

Effectiveness of Conservative Treatment According to Severity and Systemic Disease in Carpal Tunnel Syndrome: A Systematic Review

(1) Background: Carpal tunnel syndrome (CTS) is the most common peripheral neuropathy in the upper extremity. Conservative treatment has been effective for mild and moderate idiopathic CTS. However, severe CTS and systemic conditions were an exclusion criterion from the studies. The aim of this study is to review the effectiveness of conservative treatment in patients with CTS regardless of the level of severity and the presence or not of systemic diseases in the last ten years. (2) Methods: Randomized controlled clinical trials that compared the effect of conservative treatment on the Boston questionnaire and pain were selected. PubMed, PEDro, Scopus, Cochrane, and Web of Science databases were used. PRISMA statement checklist was performed. (3) Results: 876 studies were recorded, 29 were selected. Pharmacology, Electrotherapy and Manual Therapy had benefits for CTS. Electrotherapy and manual therapy could be effective for severe CTS patients with a systemic condition in the short term, but there was a low percentage of these patients included in the studies. (4) Conclusion: Some pharmacological treatments, manual therapy and electrotherapy have shown benefits for handling CTS, although the most effective combination of techniques is unknown. It would be necessary to include patients with systemic conditions in the selection criteria for future studies.

Dextrose Prolotherapy to Treat Pain, Improve Activities of Daily Living, and Improve Quality of Life in an Ewing's Sarcoma Patient Following Radiation and Chemotherapy Treatment

Advances in the treatment and survival of Ewing’s sarcoma patients create a need to treat underlying symptoms that limit activities of daily living and quality of life. This case describes the treatment of pain in a 25-year-old female pediatric nurse with Ewing’s sarcoma of the pelvis that was in remission following radiation and chemotherapy. She reported medication side effects and limitations in her activities of daily living and quality of life with the chronic use of topical and oral pain medications. A dextrose prolotherapy approach was used to treat her pain, which allowed her to discontinue her pain medication regimen, resulting in an improvement in her activities of daily living and quality of life. The improvement was sustained at the three-year follow-up after the last procedure.

Effectiveness of Perineural Injections Combined with Standard Postoperative Total Knee Arthroplasty Protocols in the Management of Chronic Postsurgical Pain After Total Knee Arthroplasty

Background

Despite increased experience and technical developments in total knee arthroplasty (TKA), chronic postsurgical pain (CPSP) remains one of physicians’ biggest challenges. The aim of the present study was to evaluate the effectiveness of perineural injection therapy (PIT) in the management of CPSP after TKA.

Material/Methods

A total of 60 patients who had been surgically treated with TKA because of advanced knee osteoarthritis was included in the present study. The study included 2 groups. Group A consisted of patients who received 3 rounds of PIT combined with standard postoperative TKA protocol during the same period. Group B received standard postoperative TKA protocols (rehabilitation programs, oral and intravenous analgesics). Clinical effectiveness was evaluated via Western Ontario and McMaster Universities Arthritis Index (WOMAC) and Visual Analog Scale (VAS) at baseline and 1-, 3-, and 6-month follow-ups.

Results

All repeated measures showed significant improvements (P<0.001) in both groups for VAS and WOMAC scores. These scores were significantly better in group A in all follow-up periods compared with group B (P<0.001). Twenty-nine patients (93.5%) in group A reported excellent or good outcomes compared with 26 patients (89.6%) in group B.

Conclusions

PIT is a promising approach in CPSP with minimal cost, simple and secure injection procedures, minimal side effects, and higher clinical efficacy.

The proper concentrations of dextrose and lidocaine in regenerative injection therapy: in vitro study

Background

Prolotherapy is a proliferation therapy as an alternative medicine. A combination of dextrose solution and lidocaine is usually used in prolotherapy. The concentrations of dextrose and lidocaine used in the clinical field are very high (dextrose 10%-25%, lidocaine 0.075%-1%). Several studies show about 1% dextrose and more than 0.2% lidocaine induced cell death in various cell types. We investigated the effects of low concentrations of dextrose and lidocaine in fibroblasts and suggest the optimal range of concentrations of dextrose and lidocaine in prolotherapy.

Methods

Various concentrations of dextrose and lidocaine were treated in NIH-3T3. Viability was examined with trypan blue exclusion assay and 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide assay. Migration assay was performed for measuring the motile activity. Extracellular signal-regulated kinase (Erk) activation and protein expression of collagen I and α-smooth muscle actin (α-SMA) were determined with western blot analysis.

Results

The cell viability was decreased in concentrations of more than 5% dextrose and 0.1% lidocaine. However, in the concentrations 1% dextrose (D1) and 0.01% lidocaine (L0.01), fibroblasts proliferated mildly. The ability of migration in fibroblast was increased in the D1, L0.01, and D1 + L0.01 groups sequentially. D1 and L0.01 increased Erk activation and the expression of collagen I and α-SMA and D1 + L0.01 further increased. The inhibition of Erk activation suppressed fibroblast proliferation and the synthesis of collagen I.

Conclusions

D1, L0.01, and the combination of D1 and L0.01 induced fibroblast proliferation and increased collagen I synthesis via Erk activation.

Acute ankle sprain in athletes: Clinical aspects and algorithmic approach

Acute ankle sprain is the most common lower limb injury in athletes and accounts for 16%-40% of all sports-related injuries. It is especially common in basketball, American football, and soccer. The majority of sprains affect the lateral ligaments, particularly the anterior talofibular ligament. Despite its high prevalence, a high proportion of patients experience persistent residual symptoms and injury recurrence. A detailed history and proper physical examination are diagnostic cornerstones. Imaging is not indicated for the majority of ankle sprain cases and should be requested according to the Ottawa ankle rules. Several interventions have been recommended in the management of acute ankle sprains including rest, ice, compression, and elevation, analgesic and anti-inflammatory medications, bracing and immobilization, early weight-bearing and walking aids, foot orthoses, manual therapy, exercise therapy, electrophysical modalities and surgery (only in selected refractory cases). Among these interventions, exercise and bracing have been recommended with a higher level of evidence and should be incorporated in the rehabilitation process. An exercise program should be comprehensive and progressive including the range of motion, stretching, strengthening, neuromuscular, proprioceptive, and sport-specific exercises. Decision-making regarding return to the sport in athletes may be challenging and a sports physician should determine this based on the self-reported variables, manual tests for stability, and functional performance testing. There are some common myths and mistakes in the management of ankle sprains, which all clinicians should be aware of and avoid. These include excessive imaging, unwarranted non-weight-bearing, unjustified immobilization, delay in functional movements, and inadequate rehabilitation. The application of an evidence-based algorithmic approach considering the individual characteristics is helpful and should be recommended.

Prolotherapy agent P2G is associated with upregulation of fibroblast growth factor-2 genetic expression in vitro

Purpose

Osteoarthritis (OA) is a prevalent, progressively degenerative disease. Researchers have rigorously documented clinical improvement in participants receiving prolotherapy for OA. The mechanism of action is unknown; therefore, basic science studies are required. One hypothesized mechanism is that prolotherapy stimulates tissue proliferation, including that of cartilage. Accordingly, this in vitro study examines whether the prolotherapy agent phenol-glycerin-glucose (P2G) is associated with upregulation of proliferation-enhancing cytokines, primarily fibroblast growth factor-2 (FGF-2).

Methods

Murine MC3T3-E1 cells were cultured in a nonconfluent state to retain an undifferentiated osteochondroprogenic status. A limitation of MC3T3-E1 cells is that they do not fully reproduce primary human chondrocyte phenotypes; however, they are useful for modeling cartilage regeneration in vitro due to their greater phenotypic stability than primary cells. Two experiments were conducted: one in duplicate and one in triplicate. Treatment consisted of phenol-glycerin-glucose (P2G, final concentration of 1.5%). The results were assessed by quantitative Reverse Transcriptase-Polymerase Chain Reaction (qRT-PCR) to detect mRNA expression of the FGF-2, IGF-1, CCND-1 (Cyclin-D), TGF-β1, AKT, STAT1, and BMP2 genes.

Results

P2G - treated preosteoblasts expressed higher levels of FGF-2 than water controls (hour 24, p < 0.001; hour 30, p < 0.05; hour 38, p < 0.01). Additionally, CCND-1 upregulation was observed (p < 0.05), possibly as a cellular response to FGF-2 upregulation.

Conclusions

The prolotherapy agent P2G appears to be associated with upregulation of the cartilage cell proliferation enhancer cytokine FGF-2, suggesting an independent effect of P2G consistent with clinical evidence. Further study investigating the effect of prolotherapy agents on cellular proliferation and cartilage regeneration is warranted.

Comparison of ultrasound-guided platelet-rich plasma, prolotherapy, and corticosteroid injections in rotator cuff lesions

BACKGROUND

Injections are a good alternative to conventional treatment-resistant cases with rotator cuff (RC) lesions before operation. Currently, different injection methods are used in RC lesions.

OBJECTIVE

To evaluate the efficacy of different injection methods (platelet-rich plasma [PRP], corticosteroid [COR] and prolotherapy [PRO]) in RC tendon lesions.

METHODS

One hundred and twenty-nine patients were divided into 4 groups as PRP, COR, PRO and the lidocaine group. Subacromial injection was applied to all groups. They were evaluated using the Visual Analogue Scale (VAS), American Shoulder and Elbow Surgeons Standardized Shoulder Assessment Form (ASES), and Western Ontario Rotator Cuff Index (WORC) at 3, 12 and 24 weeks post-injection.

RESULTS

In the COR group in the 3rd week, VAS and WORC scores were significantly lower than the other groups (p< 0.01 and p< 0.05 respectively). In the PRP group in the 24th week, VAS and WORC scores were found to be significantly lower than the COR group (p< 0.01 and p< 0.05 respectively). In the COR group in the 3rd week the ASES score was found to be significantly higher than the PRP and PRO group (p< 0.01).

CONCLUSION

In patients with RC lesions, corticosteroid injection provides short-term relief for pain, function, and quality of life, while PRP injection works for long-term wellbeing. For all types of applied injections, improvement in pain, function and quality of life were observed.

Effects of Hyperosmolar Dextrose Injection in Patients With Rotator Cuff Disease and Bursitis: A Randomized Controlled Trial

OBJECTIVE

To determine whether dextrose prolotherapy offers clinical benefits in patients with shoulder pain and bursitis.

DESIGN

Double-blinded, randomized controlled trial.

SETTING

Outpatient rehabilitation department of a single medical center.

PARTICIPANTS

Patients (N=50) who had received a diagnosis of shoulder pain and bursitis through clinical tests and ultrasound examination.

INTERVENTIONS

Participants were randomly assigned to the 15% dextrose injection (D15W) group or the placebo group to receive either D15W or normal saline injection, respectively. All participants received ultrasound-guidance bursal injection every 2 weeks for a total of 3 injections.

MAIN OUTCOME MEASURES

The primary outcome was maximal pain level while performing activities. The secondary outcomes included resting pain level, function and disability assessment results, and ultrasonographic parameters. Participants were followed up for 3 months after completion of the injection course.

RESULTS

No significant differences in baseline characteristics were observed between the D15W and placebo groups. Significant time effects were observed for all outcome parameters (all P<.05); however, time × group effects were nonsignificant for all outcomes, except for tissue elasticity (P=.026).

CONCLUSIONS

Supporting evidence is insufficient regarding the clinical benefits of 15% dextrose bursal injection administered through 3 sessions in patients with chronic shoulder pain and bursitis. The findings indicate that these injections may increase the tissue stiffness of the supraspinatus tendon, as indicated by elastography assessment results, but further research is required to determine the nature of such changes in elastography findings.

Knowledge level and attitude towards complementary and alternative treatment methods among medical students: a cross-sectional survey study in Turkey

OBJECTIVE

People often use complementary and alternative medicine (CAM) methods in Turkey, but reliability of the application of these methods is controversial. Considering the role of medical students (i.e. physician candidates) in sustainable health, their perspectives on CAM methods are important. This report explores the level of knowledge, experience, and preferences for the use of CAM methods among medical school students.

MATERIAL AND METHODS

A survey about the use of CAM and interest in CAM methods was applied to 101 first-year and 87 fifth-year medical school students. The binary and multinomial logistic regression models were used for statistical analysis.

RESULTS

Sixteen percent of the first-year and 9% of the fifth-year students were familiar with "The Regulation on Traditional and Complementary Medical Practices" published by the Ministry of Health of Turkey in 2014. While participants reported the most familiarity with acupuncture treatment, they were the most unfamiliar with prolotherapy among all CAM methods. Seeking advice from a licensed physician before applying CAM methods was the general agreement among the participants. Interest in learning and practicing hypnosis was the highest-rated CAM method among the participants.

CONCLUSIONS

Increasing knowledge and awareness of CAM methods by including them into the medical curriculum would be essential for the correct use of CAM methods.

The Effects of Dextrose Prolotherapy in Symptomatic Knee Osteoarthritis: A Randomized Controlled Study

Objective: To investigate the effects of dextrose prolotherapy in patients with knee osteoarthritis (KOA). Design: A prospective, randomized-controlled interventional trial. Setting: An outpatient pain medicine clinic. Participants: The study included 66 patients aged 40-70 years with chronic knee pain refractory to conservative therapy and diagnosed as grade II or III KOA according to the Kellgren-Lawrence classification. The patients were assigned to dextrose prolotherapy group (PG; n = 22), saline group (SG; n = 22), or control group (CG; n = 22). Interventions: The intra- and extra-articular dextrose prolotherapy and saline injections were administered to the PG and SG, respectively, at 0, 3, and 6 weeks. The patients were blinded to their injection group status. A home-based exercise program was prescribed for all patients in all three groups. Outcome measures: The Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) scores, activity pain, stiffness severity measured using a visual analog scale (VAS), and the health-related quality of life (HRQoL) scores measured using the Short Form-36 (SF-36) subscales were recorded at the baseline, 6-week, and 18-week follow-ups. Results: The WOMAC-pain and VAS-activity pain scores decreased significantly in the PG compared to the SG (p = 0.002 and p < 0.001, respectively) and CG (p < 0.001 and p < 0.001, respectively) at 18 weeks. The WOMAC-stiffness scores decreased in the PG compared to the CG at 18 weeks (p < 0.001). The WOMAC physical functioning scores were improved in the PG compared to the CG at 18 weeks (p < 0.001). The physical component scores of the HRQoL were significantly improved in the PG compared to the CG at 18 weeks (p = 0.016), but the mental component scores of the HRQoL showed no significant differences. Conclusions: These findings suggest that dextrose prolotherapy is effective at reducing pain and improving the functional status and quality of life in patients with KOA.

Treatment strategies for ischiofemoral impingement: a systematic review

PURPOSE

There has been relatively little information about the treatment for ischiofemoral impingement (IFI) because of its rarity as well as the uncertainty of diagnosis. The aim of this study was to provide the reader with the available treatment strategies and their related outcomes for IFI based on the best available evidence, whilst highlighting classically accepted ways of treatment as well as relatively new surgical and non-surgical techniques.

METHODS

A systematic review of the literature from Medline, Embase, AMED, Cochrane and Google Scholar was undertaken since inception to December 2017 following the PRISMA guidelines. Clinical outcome studies, prospective/retrospective case series and case reports that described the treatment outcome for IFI were included. Animal or cadaveric studies, trial protocols, diagnostic studies without any description of treatments, technical notes without any results, and review articles were excluded.

RESULTS

This systematic review found 17 relevant papers. No comparative studies were included in the final records for qualitative assessment, which means all the studies were case series and case reports. Eight studies (47.1%) utilised non-surgical treatment including injection and prolotherapy, followed by endoscopic surgery (5 studies, 29.4%) then open surgery (4 studies, 23.5%). Mean age of the participants was 41 years (11-72 years). The mean follow-up was 8.4 months distributed from 2 weeks to 2.3 years. No complications or adverse effects were found from the systematic review.

CONCLUSION

Several treatment strategies have been reported for IFI, and most of them have good short- to medium-term outcomes with a low rate of complications. However, there are no comparative studies to assess the superiority of one technique over another, thus further research with randomised controlled trials is required in this arena. This study explores the wide variety and categories of different treatments used for IFI to guide physicians and shed light on what can be done for this challenging cohort of patients.

Periarticular hypertonic dextrose vs intraarticular hyaluronic acid injections: a comparison of two minimally invasive techniques in the treatment of symptomatic knee osteoarthritis

Background

Knee osteoarthritis (KOA) is the most prevailing form of joint disease. Despite the importance of minimally invasive therapeutic methods of KOA, there is a lack of evidence to compare intraarticular hyaluronic acid injection vs traditional dextrose prolotherapy.

Objective

The aim was to compare the therapeutic effects of prolotherapy with hypertonic dextrose vs hyaluronic acid on function and pain in KOA cases.

Materials and methods

One hundred and four KOA patients were enrolled and randomly assigned into two groups, each containing 52 patients. The hyaluronic acid (HA) group were treated by 2.5 mL of hyaluronic acid intraarticulary, and the hypertonic dextrose (HD) group received 10 mL of 12.5% dextrose periarticulary. Injections were repeated three times with 1-week intervals. Pain intensity, measured by visual analog scale, and knee function, scaled by the Western Ontario and McMaster university arthritis index scores were compared between the two groups before and 3 months after intervention. Pain and function of the knee improved significantly (P<0.001) in all patients. However, significantly more symptom relief was found in the HA over the HD group. Prolotherapy with hypertonic dextrose and intraarticular injection of hyaluronic acid results in the same pain reduction and symptom relief as a noninvasive therapeutic method of KOA.

Conclusion

These results recommended intraarticular hyaluronic acid rather than prolotherapy by hypertonic dextrose for KOA symptoms relief.

Dextrose injections for failed back surgery syndrome: a consecutive case series

PURPOSE

Patients with chronic low back pain, who do not respond to conservative treatment methods, generally undergo surgical revision operations, and sometimes an undesirable condition called failed back surgery syndrome (FBSS) may be inevitable. Hereby, dextrose is one of the regenerative methods that has gained popularity in the treatment of many musculoskeletal problems, and we aimed to present and evaluate the outcomes of 5% dextrose for the treatment of FBSS.

METHODS

It has been designed as a consecutive case series. A total of 79 patients with FBSS, who had minimum 6 months of symptoms and did not respond to 3 months of conservative methods between May 2014 and March 2016, participated in the study. Prolotherapy injections were applied in posterior and lateral approaches. Visual Analog Scale (VAS) and Oswestry Disability Index (ODI) were used for the pre- and post-treatment evaluations. Patient satisfaction was assessed with using a 5-point Likert scale by phone contacting.

RESULTS

There was statistically significant difference between repeated VAS and ODI measurements.

CONCLUSIONS

These results may be the first step giving a lead to an undiscovered field. This treatment method should be kept in mind for FBSS patients before giving a decision of revision surgery. These slides can be retrieved under Electronic Supplementary Material.

Prolotherapy: Potential for the Treatment of Chronic Wounds?

Significance: Chronic skin ulcers, including venous, diabetic, and pressure ulcers, constitute a major health care burden, affecting 2-6 million people in the United States alone, with projected increases in incidence owing to the aging population and rising epidemic of diabetes. The ulcers are often accompanied by pain. Standard of care fails to heal ∼50% of diabetic foot ulcers and 25% of venous leg ulcers. Even advanced therapies do not heal >60%. Thus there is an unmet need for novel therapies that promote healing and also address the concomitant pain issue. Recent Advances: Prolotherapy involves injection of small amounts of an irritant material to the site of degenerated or painful joints, ligaments, and tendons. Multiple irritants are reported to be efficacious, but the focus here is on dextrose prolotherapy. In vitro and in vivo studies support translation to clinical use. Concentrations as low as 5% dextrose have resulted in production of growth factors that have critical roles in repair. Numerous clinical trials report pro-reparative effects of dextrose prolotherapy in joint diseases, tendon, and ligament damage, and for painful musculoskeletal issues. However, most of the studies have limitations that result in low-quality evidence. Critical Issues: The preclinical data support a role for dextrose prolotherapy in promoting tissue repair that is required for healing chronic wounds and ameliorating the associated pain. Critical issues include provision of evidence of efficacy in human chronic wounds. Another potential obstacle is limitation of reimbursement by third-party payers for a therapy with as yet limited evidence. Future Directions: Preclinical studies in models of chronic wounds would support clinical translation. As dextrose prolotherapy has some mechanistic similarities to already approved honey therapies, it may have a shortened pathway for clinical translation. The gold standard for widespread adoption would be a well-designed clinical trial.

Regenerative injection therapy and repetitive transcranial magnetic stimulation in primary fibromyalgia treatment: A comparative study

OBJECTIVE

This study compared the effectiveness of regenerative injection therapy (RIT), i.e. prolotherapy, and repetitive transcranial magnetic stimulation (rTMS) in the treatment of fibromyalgia syndrome.

PATIENTS AND METHODS

This study included 120 female, age-matched fibromyalgia patients. All patients underwent a clinical examination, pain assessment by VAS, assessment of tender points, psychiatric and functional assessment using the Beck Depression Inventory (BDI), Fibromyalgia Impact Questionnaire Revised (RFIQ), and measurement of cortical auditory evoked potentials CAEPs elicited at 1000 Hz. Patients were divided into two equal groups; Group 1 received prolotherapy three times, two weeks apart, and Group 2 received rTMS sessions every other day for one month. Assessment was performed before treatment, immediately after treatment, and one month later.

RESULTS

A significant improvement of pain measured by the mean score of VAS was remarked in Group 1 compared to Group 2 immediately after treatment and one month later. There was statistically significant difference of mean scores for the number of tender points in Group 1 compared to Group 2 after treatment and one month later. The patients improved functionally, with a statistically significant difference in mean score of RFIQ, in Group 1 compared to Group 2 one month after treatment. However, there was a significant difference in mean score of BDI in Group 2 compared to Group 1 after treatment and one month later. Further, CAEPs showed better improvement, with a significant difference in Group 2, one month after treatment.

CONCLUSION

RIT had the advantage in clinical and functional improvement in fibromyalgia patients, while rTMS had better results regarding depression and the cortical component of AEPs. These results might draw attention to the evaluability of a combination of both techniques for a better therapeutic response.

Utility of Prolotherapy for Upper Extremity Pathology

Prolotherapy is a method of treatment of painful musculoskeletal conditions whereby a sclerosing agent is injected into an area of tendinosis or osteoarthritis to strengthen and repair painful connective tissue. It is a safe, effective, and relatively inexpensive nonsurgical treatment modality. This article provides a history of prolotherapy, discusses its proposed mechanisms of action, and provides a review of the existing literature on prolotherapy as a treatment for upper extremity pathologies, specifically, hand osteoarthritis, lateral epicondylitis, and rotator cuff disease.

Between May 2014 and March 2016, a total of 15 patients (5 males, 10 females; mean age 49.4±10.7 years; range, 33 to 71 years) with failed rotator cuff repair surgery who had at least six months of complaints and were refractory to at least of three months of conservative methods were included. Ultrasound-guided prolotherapy injections were performed under aseptic conditions, and the patients were instructed to carry out a home-based exercise program. Clinical assessment of shoulder function was performed using a visual analog scale (VAS) for pain, Shoulder Pain and Disability Index (SPADI), Western Ontario Rotator Cuff (WORC) Index, patient satisfaction and shoulder range of motion. All patients were examined at baseline, at Week 3, 6, and 12 and at the final follow-up visit.

Results

The intra-group comparison showed that the patients achieved significant improvements at all time points, compared to baseline as measured by VAS, SPADI, WORC index, and shoulder range of motion (p<0.001). Twelve patients (80%) reported excellent or good outcomes.

Conclusion

Our study results show that prolotherapy is effective in the treatment of patients with failed rotator cuff repair surgery with significant improvements in the shoulder functions and pain relief.

Ultrasound-guided injections for supraspinatus tendinopathy: corticosteroid versus glucose prolotherapy - a randomized controlled clinical trial

BACKGROUND

Subacromial corticosteroid injections are frequently performed for pain associated with supraspinatus tendinopathy. Glucose prolotherapy has been used clinically for multiple tendinopathies and is hypothesized to be an alternate injection therapy for supraspinatus tendinopathy.

METHODS

A prospective, randomized, double blinded clinical trial was conducted. Thirty-six patients with supraspinatus tendinopathy were randomized into two groups: 17 received an ultrasound-guided injection of glucose into the tendinopathic parts of the supraspinatus tendon and 19 received an ultrasound-guided injection of corticosteroid into the subacromial bursa. Primary outcome was level of pain with overhead activities at 3 months. Secondary outcome measures included level and frequency of pain and function, shoulder range of motion, impingement tests, strength and tendon changes on ultrasound.

RESULTS

Level of pain with overhead activities was significantly reduced at the 3-month follow-up in the prolotherapy group and at the 6-month follow-up for both the prolotherapy and corticosteroid groups. There were no significant differences between the groups at any time point.

CONCLUSIONS

Both glucose prolotherapy and corticosteroid were generally well tolerated; however, glucose prolotherapy offered no additional benefit over subacromial corticosteroid injection for supraspinatus tendinopathy.
