Regenerative Medicine in Orthopedic Surgery: Expanding Our Toolbox.

Regenerative medicine leverages the body's inherent regenerative capabilities to repair damaged tissues and address organ dysfunction. In orthopedics, this approach includes a variety of treatments collectively known as orthoregeneration, encompassing modalities such as prolotherapy, extracorporeal shockwave therapy, pulsed electromagnetic field therapy, therapeutic ultrasound, and photobiomodulation therapy, and orthobiologics like platelet-rich plasma and cell-based therapies. These minimally invasive techniques are becoming prominent due to their potential for fewer complications in orthopedic surgery. As regenerative medicine continues to advance, surgeons must stay informed about these developments. This paper highlights the current state of regenerative medicine in orthopedics and advocates for further clinical research to validate and expand these treatments to enhance patient outcomes.

Post-mechanotherapy differences in postural control in patients with Achilles tendinopathy - A randomized controlled trial.

BACKGROUND: Neuromuscular deficits affecting functional ability can occur in patients with Achilles tendinopathy during difficult balance activities. This study aimed to assess postural control in patients with Achilles tendinopathy after shockwave and sonotherapy, using advanced analytical methods, including rambling-trembling signal decomposition and sample entropy. RESEARCH QUESTION: What are the differences in postural control between patients with Achilles tendinopathy after shockwave therapy, ultrasound therapy, and placebo ultrasound? METHODS: Thirty-nine patients were included in the study, and randomly assigned to 3 groups, i.e., shockwave therapy, ultrasound therapy and placebo ultrasound. Postural sway was assessed during quiet standing with eyes open and closed, with two force platforms, one for the affected and the other for the non-affected limb, at baseline and at weeks 1 and 6 after treatment. Rambling-trembling trajectories and sample entropy were calculated for the antero-posterior and medio-lateral directions. RESULTS: The parameters of trembling trajectory in both directions were significantly smaller for the affected compared to non-affected limb. The ultrasound group had significantly larger rambling-trembling trajectories in the antero-posterior and medio-lateral sway directions than the shockwave therapy group. Also, all patients had more difficulty controlling their postural sway while standing with eyes closed compared to eyes open. Sample entropy was not significantly affected by the therapy type, timepoint and limb condition. SIGNIFICANCE: As opposed to sample entropy, rambling-trembling decomposition can complement or replace traditional linear measures of COP time series in functional assessment of the Achilles tendon.

The dose effectiveness of extracorporeal shockwave on plantar flexor spasticity of ankle in stroke patients: a randomized controlled trial.

BACKGROUND: Extracorporeal shockwave therapy (ESWT) has been proven beneficial for post-stroke spasticity (PSS) of ankle plantar flexor muscles. This study aims to investigate the dose-response effectiveness of focused-ESWT and the duration of its effect on the treatment of ankle PSS in stroke patients. METHODS: In this double-blinded randomized controlled trial, stroke patients diagnosed with PSS in the ankle plantar flexor muscles were randomly assigned to two groups. The experimental group received double-dose ESWT (4000 pulses per session) targeting spastic calf muscles, while the control group received half the dose (2000 pulses per session). Both groups underwent four sessions over two weeks. The outcomes, including modified Ashworth Scale (MAS), modified Tardieu Scale (MTS), passive range of motion (PROM) of the ankle, Timed Up and Go (TUG) Test, Barthel index and strain elastography were evaluated at baseline, 1st, 4th, 12th, and 24th week after ESWT. RESULTS: Within-group analysis revealed significant improvements in MAS, PROM, TUG Test, and Barthel index for the double-dose ESWT group and improvements in Barthel index for the control group. Between-group analysis revealed greater improvements in TUG Test, Barthel Index and strain elastography for the double-dose ESWT group. Generalized estimating equations analysis indicated that the double-dose ESWT group achieved superior outcomes in the TUG Test, Barthel Index, and strain elastography across various time points and groups. CONCLUSIONS: Double-dose ESWT showed better functional improvement and elastography compared to the control group. ESWT demonstrated dose-response effectiveness for PSS of ankle-equinus. TRIAL REGISTRATION: NCT05878223.

Outcomes After Extracorporeal Shockwave Therapy for Chronic Noninsertional Achilles Tendinopathy Compared With Chronic Insertional Achilles Tendinopathy: A Retrospective Review.

Background: Extracorporeal shockwave therapy (ESWT) is a noninvasive treatment modality that is used in the treatment of chronic Achilles tendinopathy (AT). Purposes: To (1) retrospectively assess outcomes after ESWT for both noninsertional AT (NAT) and insertional AT (IAT) at >1-year follow-up and (2) identify potential predictors of outcomes. Study Design: Cohort study; Level of evidence, 3. Methods: Chart review was conducted to identify patients who underwent ESWT for AT with a minimum of 1-year follow-up. Data collected and assessed included patient demographic characteristics, pathological characteristics including the location of AT (NAT or IAT), presence of a Haglund deformity, and severity of tendon degeneration on magnetic resonance imaging (MRI), in addition to treatment characteristics including number of sessions and intensity of ESWT. The Victorian Institute of Sports Assessment-Achilles (VISA-A) and visual analog scale (VAS) pain scores were obtained before ESWT, 6 months after ESWT, and at final follow-up. Failures were also recorded, which were defined as no improvement in VISA-A or VAS scores or need for surgical intervention. Linear regression was performed to identify potential predictors of inferior subjective clinical outcomes and failures. Survival analysis was conducted using Kaplan-Meier curves. Results: The study included 52 patients with IAT and 34 patients with NAT. The mean follow-up in the NAT cohort was 22.3 ± 10.2 months and the mean follow-up in the IAT cohort was 26.8 ± 15.8 months. Improvements in VISA-A and VAS scores were observed in the NAT cohort at 6-month follow-up and at final follow-up (P < .05). Improvements in VISA-A and VAS scores were recorded in the IAT cohort at 6-month follow-up, which subsequently deteriorated at final follow-up. In the NAT cohort, the failure rate at 6-month follow-up was 11.8%, which increased to 29.4% at final follow-up. In the IAT cohort, the failure rate at 6-month follow-up was 32.7%, which increased to 59.6% at final follow-up. Predictors of inferior subjective clinical outcomes and failures in the NAT cohort included pre-ESWT subjective clinical score, male sex, presence of a cardiovascular risk factor, and more severe MRI grading of tendinopathy. Predictors of inferior subjective clinical outcomes and failures in the IAT cohort included pre-ESWT subjective clinical score and more severe MRI grading of tendinopathy. Conclusion: Superior subjective clinical outcomes together with a lower failure rate were maintained for >1 year in the NAT cohort compared with the IAT cohort, calling into question the long-term benefit of ESWT for patients with IAT.

Microenergy shockwave therapies for female stress urinary incontinence.

Stress urinary incontinence (SUI) is one of the pelvic floor disorders affecting tens of million of women worldwide. In general, non-surgical options have relatively limited efficacy. The most effective treatment is mid-urethral sling surgery which carries substantial risks of perioperative and postoperative complications. Regenerative therapy with the injection of several types of stem cells and stem cell products is promising but further investigation is needed before clinical implementation can be considered. In recent years, the application of microenergy therapy as a non-invasive treatment for SUI has received increasing attention. Preclinical animal studies of these models have demonstrated that low-intensity extracorporeal shockwave therapy (Li-ESWT) and microenergy acoustic pulse (MAP) therapy are capable of regenerating urethral sphincter tissue and pelvic floor muscles leading to improved urinary continence. One pilot clinical trial with Li-ESWT also reported improved quality of life in women with SUI as well as the symptoms. The objective of this review is to summarize the potential mechanisms associated with Li-ESWT and MAP therapies of SUI: (I) activation of tissue-resident stem cells; (II) regeneration of musculature in the urethra and pelvic floor; (III) improvement in biomechanical property of pelvic floor muscles; (IV) modulation of cellular signaling pathways. Further studies of the molecular mechanisms, optimal treatment dosage and schedule, and potential long-term side effects are needed to provide this non-invasive regenerative therapy for millions of women with SUI.

The role of gut microbiota involved in prostate microenvironment and symptoms improvement in chronic prostatitis/chronic pelvic pain syndrome patients treated with low-intensity extracorporeal shock wave.

BACKGROUND: Low-intensity extracorporeal shockwave therapy (Li-ESWT) is emerging as a promising and safe treatment for Chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS). In this study, we aimed to investigate the role of the gut microbiota involved in the prostate microenvironment and symptom improvement during the Li-ESWT for CP/CPPS patients. METHODS: CP/CPPS patients not taking antibiotics or other treatments were included. NIH-Chronic Prostatitis Symptom Index (NIH-CPSI), International Prostate Symptom Score (IPSS), and International Index of Erectile Function (IIEF-5) were used to evaluate the effectiveness of Li-ESWT at the end of treatment. Visual analogue scale/score was used to evaluate the pain during procedure. Stool and semen samples were collected before and after Li-ESWT. Shotgun metagenomics analyzed gut microbiota, while ELISA and other diagnostic kits detected biochemical changes in seminal plasma. RESULT: Of the 60 enrolled patients, 52 completed treatment. Li-ESWT response rate was 78.8% (41/52) at end of treatment. Among responders, the subitems of the NIH-CPSI; IPSS; and IIEF-5 scores improved significantly, and the seminal plasma analysis showed decreased TNF-a and MDA levels and increased SOD and Zn2+ levels posttreatment. Gut microbiome analysis indicated that posttreatment, both α and ß diversity increased, and the abundance of certain specific species significantly increased. Fifty-eight pathways significantly enriched posttreatment, notably in branched-chain amino acid synthesis and butyrate synthesis. The abundance of several specific species was found to be significantly higher in non-responders than responders. Among responders, at the species level, some bacteria associated with NIH-CPSI and its subscales, IPSS, IIEF-5, and prostate microenvironment markers (TNF-a, MDA, Zn2+, and SOD) were identified. CONCLUSIONS: Our study demonstrates for the first time that Li-ESWT improves the prostate microenvironment and gut microbiota in CP/CPPS patients. Treatment nonresponse may be associated with a high abundance of specific pathogens before treatment. The gut microbiota could have a significant impact on Li-ESWT response and the prostate microenvironment.

Extracorporeal shock wave therapy (ESWT) favors healing of diabetic foot ulcers: A systematic review and meta-analysis.

AIMS: To investigate the efficacy and safety of extracorporeal shockwave therapy(ESWT) for diabetic foot ulcers(DFUs). METHODS: Search in PubMed, EMBASE, the Cochrane Controlled Register of Trials (CENTAL), and Web of Science for randomized controlled trials (RCTs) published before August 8, 2023. All identified studies were screened following the selection criteria. Finally, we employed the STATA 14.0 software for conducting a meta-analysis to evaluate the efficacy and safety of ESWT. RESULTS: A total of ten RCTs with moderate methodological quality were included for data analysis. The findings showed that ESWT was significantly associated with significantly complete healed ulcers (risk ratio [RR]: 1.57, 95 % confidence interval [CI]:1.26 to 1.95) and lower rate of unchanged ulcers (RR: 0.25, 95 %CI: 0.14 to 0.42) compared to controls. Subgroup analysis further revealed that ESWT was better than both hyperbaric oxygen therapy (HOT) and the standard of care (SOC). Moreover, ESWT also significantly improved the average transcutaneous partial oxygen pressure (TcPO2) (mean difference[MD]: 1.71, 95 %CI: 1.22 to 2.19, p < 0.001). However, the rate of ≥ 50 % improved ulcers and treatment-emergent adverse events (TEAEs) were not significantly different between the ESWT and controls. CONCLUSIONS: ESWT has shown promising efficacy and a favorable safety profile in the treatment of DFUs.

High Versus Low-Energy Extracorporeal Shockwave Therapy for Chronic Lateral Epicondylitis: A Retrospective Study.

Background: Chronic lateral epicondylitis (LE), also known as tennis elbow, affects 1-3% of the population, primarily those over 40 years old. Most cases resolve with conservative treatments, but some require more advanced interventions. Extracorporeal shockwave therapy (ESWT) has emerged as a non-surgical treatment option, utilizing either low- or high-energy levels to alleviate pain and improve function. Objective: This study aimed to compare the efficacy of low-energy versus high-energy ESWT in the treatment of chronic LE, focusing on pain relief and functional improvement. Methods: A retrospective observational study was conducted including patients treated for chronic LE between 2021 and 2024. Participants were divided into two groups: low-energy ESWT (0.10 mJ/mm2) and high-energy ESWT (0.20 mJ/mm2). Both groups received 2400 pulses at a frequency of 6 Hz once a week for three weeks. Pain and functional outcomes were measured using a visual analog scale (VAS) and the Patient-Rated Tennis Elbow Evaluation Questionnaire (PRTEE) at the baseline, three months (T1), and six months (T2) post-treatment. Results: Forty-six patients participated, with 24 in the low-energy group and 22 in the high-energy group. Baseline demographics and clinical characteristics were similar across groups. At T1 and T2, the low-energy group showed significantly greater reductions in the VAS scores (T1: 4.45 ± 0.8 vs. 3.6 ± 1.7, p = 0.04; T2: 3.2 ± 1.2 vs. 2.1 ± 1.1, p = 0.004) and PRTEE scores (T1: 34.3 ± 6.9 vs. 26.8 ± 11.9, p = 0.03; T2: 25.3 ± 6 vs. 17.6 ± 9, p = 0.005). Significant treatment-time interactions were observed for both the VAS and PRTEE scores, indicating sustained improvements in the low-energy group. Conclusions: Low-energy ESWT was more effective than high-energy ESWT in treating chronic LE, providing greater and longer-lasting pain relief and functional improvement. These findings suggest that low-energy ESWT should be preferred in clinical practice for managing this condition. Future research should focus on larger sample sizes and randomized controlled trials to confirm these results and explore the underlying mechanisms of differential efficacy between energy levels.

Extracorporeal shockwave therapy for degenerative meniscal tears results in a decreased T2 relaxation time and pain relief: An exploratory randomized clinical trial.

PURPOSE: The optimal management of degenerative meniscal tears remains controversial. Extracorporeal shockwave therapy (ESWT) has been shown to promote tissue repair in both preclinical and clinical studies; however, its effect on degenerative meniscal tears remains unknown. This study aimed to examine whether ESWT improves meniscal degeneration. METHODS: This randomized trial was conducted between 2020 and 2022 and involved patients with degenerative medial meniscal tears. Patients were allocated to receive either focused ESWT (0.25 mJ/mm2, 2000 impulses, 3 sessions with a 1-week interval) or sham treatment. Patients were evaluated using magnetic resonance imaging (MRI) before treatment and at 12 months after treatment. The primary endpoint was improvement in meniscal degeneration, as assessed by the change in T2 relaxation time from baseline on MRI T2 mapping. Knee pain and clinical outcomes were also examined at the same time. RESULTS: Of 29 randomized patients, 27 patients (mean age 63.9 ± 8.7 years; females 37%; ESWT group 14 patients; control group 13 patients) were included in the final analysis. At 12 months postintervention, patients in the ESWT group showed a greater decrease in the T2 relaxation time (ESWT group -2.9 ± 1.7 ms vs. control group 1.0 ± 1.9 ms; p < 0.001) and had less knee pain (p = 0.04). The clinical outcomes at 12 months post-treatment were not statistically significant. No adverse events were reported. CONCLUSION: ESWT decreased the T2 relaxation time in the meniscus at 12 months post-treatment. ESWT also provided pain relief, but no differences were observed in clinical outcomes. LEVEL OF EVIDENCE: Level II.

Evidence of restorative therapies in the treatment of Peyronie disease: A narrative review.

OBJECTIVE: To describe the evidence of Platelet Rich Plasma (PRP), Stem cells therapy (SCT) and Extracorporeal shockwave therapy (ESWL) for the treatment of Peyronies disease (PD), including information from the main urological society guidelines. MATERIALS AND METHODS: A literature review of PubMed articles published between 2000 and 2023 was conducted, utilizing keywords such as "Peyronie's Disease", "Penile curvature", "Platelet Rich Plasma", "Stem cells", and "Extracorporeal shockwave therapy". Only full-text articles in English were included, excluding case reports and opinions. RESULTS: A considerable number of clinical trials were conducted using PRP penile injections for therapy of PD, showing reduction of curvature, plaque size and improvement in quality of life. Preclinical studies in rats have shown the potential benefit of adipose-derived stem cells, with improvements in erectile function and fibrosis. Human studies with mesenchymal stem cells demonstrated promising results, with reduction of curvature and plaque size. ESWL effects on PD were investigated in randomized clinical trials and demonstrated no significant impact in curvature or plaque size, but reasonable effect on pain control. CONCLUSION: Restorative therapies has emerged as an innovative treatment option for PD and the results from current studies appear to be promising and demonstrated good safety profile. Unfortunately, due to scarce evidence, PRP and SCT are still considered experimental by American Urological Association (AUA) and European Association of Urology (EAU) guidelines. ESWT is recommended, by the same guidelines, for pain control only. More high-quality studies with long-term follow-up outcomes are needed to evaluate efficacy and reproducibility of those therapies.

Effect of extracorporeal shockwave therapy on plantar fascia thickness in plantar fasciitis: a systematic review and meta-analysis of randomized controlled trials.

OBJECTIVE: Extracorporeal shockwave therapy (ESWT) has been used as a therapeutic option for plantar fasciitis. The objective was to investigate the effect of ESWT over the plantar fascia thickness. METHODS: MEDLINE, Embase, Web of Science, and SCOPUS databases were searched for randomized controlled trials evaluating the effect of ESWT in patients with plantar fasciitis, comparing ESWT with another treatment. Meta-analysis was conducted using a random-effects model and the generic inverse variance method. Meta-regression and subgroup analyses were also carried out. RESULTS: A total of 14 studies (867 participants) were included. ESWT significantly decreased plantar fascia thickness (weighted mean difference [WMD], -0.21 mm [95% CI -0.39, -0.02]; p = 0.03). No significant improvement in pain was observed (WMD, -0.51 cm [95% CI -1.04, 0.01]; p = 0.06) compared with non-surgical interventions. CONCLUSIONS: Our results suggest that plantar fascia thickness is significantly decreased after ESWT intervention in patients with plantar fasciitis. However, pain relief was not significantly improved compared to other non-surgical interventions.

Regenerative Therapy in Erectile Dysfunction: A Survey on Current Global Practice Trends and GAF Expert Recommendations.

PURPOSE: This study aimed to examine current global practices in regenerative therapy (RT) for erectile dysfunction (ED) and to establish expert recommendations for its use, addressing the current lack of solid evidence and standardized guidelines. MATERIALS AND METHODS: A 39-question survey was developed by senior Global Andrology Forum (GAF) experts to comprehensively cover clinical aspects of RT. This was distributed globally via a secure online Google Form to ED specialists through the GAF website, international professional societies, and social media, the responses were analyzed and presented for frequencies as percentages. Consensus on expert recommendations for RT use was achieved using the Delphi method. RESULTS: Out of 479 respondents from 62 countries, a third reported using RT for ED. The most popular treatment was low-intensity shock wave therapy (54.6%), followed by platelet-rich plasma (24.5%) and their combination (14.7%), with stem cell therapy being the least used (3.7%). The primary indication for RT was the refractory or adverse effects of PDE5 inhibitors, with the best effectiveness reported in middle-aged and mild-to-moderate ED patients. Respondents were confident about its overall safety, with a significant number expressing interest in RT's future use, despite pending guidelines support. CONCLUSIONS: This inaugural global survey reveals a growing use of RT in ED treatment, showcasing its diverse clinical applications and potential for future widespread adoption. However, the lack of comprehensive evidence and clear guidelines requires further research to standardize RT practices in ED treatment.

Effects of Radial Extracorporeal Shockwave Therapy on Piriformis Syndrome: A Single-Case Experimental Design.

The effects of radial extracorporeal shockwave therapy (rESWT) on piriformis syndrome were investigated using a single-case study design. This study used an AB single case with a follow-up phase design. The baseline phase consisted of general physical therapy, including piriformis stretching, while the experimental phase consisted of rESWT in addition to general physical therapy. A man in his 70s diagnosed with piriformis syndrome participated in the study. The Numerical Rating Scale (NRS) score, piriformis hardness, and cross-sectional area of the sciatic nerve were measured to determine the effectiveness of the intervention. The baseline and experimental phases were compared using a binomial distribution based on the celeration line. The NRS score, piriformis hardness, and cross-sectional area of the sciatic nerve were significantly decreased in the experimental phase compared to the baseline phase (NRS, p<0.001; piriformis hardness, p<0.001; cross-sectional area of the sciatic nerve, p<0.001). This effect was carried over to the follow-up phase for all variables. rESWT for piriformis syndrome improved the clinical symptoms, piriformis hardness, and cross-sectional area of the sciatic nerve. However, these results are exploratory and require further validation in future clinical trials.

Extracorporeal shockwave therapy in treatment of chronic prostatitis/chronic pelvic pain syndrome: Systematic review and meta-analyses.

AIMS: Chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) prevalence varies from 8.4% to 25% of the male population and is associated with diminished health-related quality of life. Managing CP/CPPS remains challenging and there is not any common option to treat all patients effectively because of the complex disease nature. The currently available data for the extracorporeal shockwave therapy (eSWT) effect on pain relief and well-being were analyzed in the present study. METHODS: We adhered to PRISMA 2022 guidelines for reporting the quantitative and qualitative data synthesis. A literature search was conducted in March 2023 using PubMed/Medline, Scopus, and Google Scholar. Randomized prospective studies of eSWT alone or eSWT plus conventional medicinal treatment were included. The risk of bias was estimated using the RoB 2.0. Primary outcomes were self-reported scores, including the NIH-CPSI questionnaire and VAS, at 1 month or 2, 3, and 6, months follow-up. RESULTS: The CP/CPPS patients who receive eSWT have more pronounced pain relief and improvement of other subjective NIH-CPSI scores compared with control groups that received placebo or medication therapy. The effect of eSWT seems to be long-lasting and was confirmed in the 6-month follow-up (p < 0.01). CONCLUSIONS: Based on the meta-analysis of accessible studies, we receive the equivalence eSWT applicability for the CP/CPPS treatment and can be offered to patients because of its noninvasiveness, high level of safety, and successful clinical results demonstrated in this analysis.

Radial Type Low-Intensity Extracorporeal Shockwave Therapy Enhances Penile Microvascular Perfusion in an Aging Rat Model: A Novel Interventional Strategy to Treat Erectile Dysfunction.

PURPOSE: Physiological aging is associated with microvascular dysfunction, including in the penis, and this may contribute to age-related erectile dysfunction (ED). Low-intensity extracorporeal shockwave therapy (Li-ESWT) is a non-invasive intervention for ED, but its effect on penile microvascular function, remains unclear. Our objectives are to (i) evaluate the effect of Li-ESWT (specifically radial type ESWT [rESWT]) on penile microvascular perfusion (PMP) in aging rats, (ii) elucidate a possible mechanism, and (iii) evaluate its impact on angiogenic and smooth muscle biomarkers in cavernosal tissue. MATERIALS AND METHODS: Male rats (n=9; 15-18 months) were anesthetized and subjected to rESWT while monitoring PMP. The nitric oxide (NO) pathway involvement was assessed by measuring the effect of rESWT on PMP following an intracavernosal injection of N(G)-nitroarginine methyl ester (L-NAME) (NO synthase inhibitor). To elucidate the cellular mechanism, another group of rats received repeated rESWT (n=4) or no treatment (n=4) three times/week for two weeks. Rats were euthanized at the end of the study and penile tissues were analyzed for angiogenic markers (vascular endothelial growth factor-A [VEGF-A], endothelial nitric oxide synthase [eNOS]) and smooth muscle content (α-actin) using immunostaining, Western blot, and quantitative polymerase chain reaction (qPCR). RESULTS: rESWT resulted in more than a 2-fold increase in PMP (from 68.5 arbitrary units; 163.7 AU). L-NAME injection produced a <40%-50% decrease (185.3 to 101.0 AU) in rESWT-induced PMP response. Immunostaining revealed increased α-actin, eNOS, and VEGF-A in the cavernosum and these findings were confirmed by qPCR and Western blot results. CONCLUSIONS: rESWT improved PMP, which may be mediated via increased VEGF expression, which stimulates the NO/cyclic guanosine monophosphate pathway, resulting in sustained PMP. rESWT devices could offer a safe, non-invasive treatment for age-related ED.

Comparison of the Short-Term Effect between Iontophoresis and Radial Extracorporeal Shockwave Therapy in the Treatment of Plantar Fasciitis: A Randomized Controlled Trial.

Conservative treatments for plantar fasciitis have different levels of effectiveness, so it is necessary to personalize the therapeutic modality that improves the patients' symptoms. METHODS: A double-blinded randomized clinical trial was designed to evaluate the short-term efficacy of a physical treatment in chronic plantar fasciitis, namely iontophoresis, compared with radial shockwave therapy. Heel pain, health status using the EuroQol-5D questionnaire, and fascia thickness measured with ultrasound were evaluated. In total, 127 patients were randomly selected for group A and treated with iontophoresis therapy (lidocaine 0.4% and dexamethasone 0.5%), or for group B, in which they were treated with radial shockwave therapy (EWST). Measurements were taken at baseline and at follow-up during the 5 weeks of the study. RESULTS: Statistically significant differences were observed to the shockwave therapy group in respect to the final fascia thickness, and the VAS scale (p = 0.001). The differences between groups A and B showed that the shockwave group follow-up after 3 weeks experienced complete pain remission (1.0 ± 0.9; 95%CI 0.8-1.2) and after the 6-week follow-up, complete pain remission of plantar fasciitis was observed for both therapies. Patients had a better perception of the use of EWST at the end of the treatment, although in both groups it was satisfactory (p = 0.001). CONCLUSIONS: The results of this study showed a shorter-term effectiveness of shockwave treatment compared with the use of iontophoresis. However, both techniques were effective in satisfactorily reducing pain in this short period.

The Effects of Shock Wave Therapy on the Symptoms and Function of Individuals With Dupuytren Disease: A Systematic Review.

OBJECTIVE: To systematically evaluate the effects of extracorporeal shockwave therapy (ESWT) on pain, clinical and functional outcomes, and satisfaction of patients with Dupuytren disease. DATA SOURCES: A thorough search for all the study types published in English was conducted in PubMed, Scopus, Web of Science, and Embase from inception to August 31, 2022. STUDY SELECTION: Title and abstract and then full-text screening against eligibility criteria was performed independently by 2 reviewers, and a third reviewer achieved consensus. DATA EXTRACTION: Reviewers identified 26 studies, of which 6 were included in the analysis (145 cases). The methodological quality was assessed using the National Heart, Lung, and Blood Institute and the Joanna Briggs Institute checklists. The certainty of evidence was evaluated using the Grading of Recommendation Assessment, Development, and Evaluation. DATA SYNTHESIS: Assessments represented a remarkable improvement in the pain and function through the measurements including the visual analog scale, the Disabilities of Arm Shoulder and Hand Questionnaire, the Michigan Hand Outcome Questionnaire, and Mayo Wrist Score. Patients' satisfaction was also favorable using the Roles and Maudsley score. The hand grip strength improvement was noted in one study measured via a Jamar dynamometer. In addition, the ultrasonographic assessment of the nodules revealed a decrease in the size of the nodules in a patient with multiple bilateral nodules after the treatment. The quality of the included studies was good for all studies except for one that was fair. The certainty of evidence was moderate for pain and function and was low for patients' satisfaction and ultrasonographic findings. CONCLUSIONS: ESWT can lead to significant pain improvement, functional rehabilitation, and patient satisfaction with no adverse effect in the management of Dupuytren disease. Pain may return over time, but not to that severity before the intervention. ESWT-related characteristics and the need for continuation of treatment remain to be fully elucidated in future large clinical trials.

A systematic review of the use of shockwave therapy for knee osteoarthritis.

Introduction: Previous studies assessed the effect of extracorporeal shockwave therapy (ESWT) for knee osteoarthritis (OA) among different situations. Thus, results from a meta-analysis regarding this topic may not be reliable due to heterogeneity. Methods: A systematic review was conducted on three internet databases, namely Cochrane Library, PubMed, and Embase, gathering pertinent papers from their establishment to March 2024. The search phrases were as follows: "shockwave" OR "shock wave" OR "extracorporeal shockwave" OR "Extracorporeal Shockwave Therapy [MeSH Term]" AND "knee" AND ("osteoarthritis" OR "arthritis" OR "arthritic" OR "osteoarthritis [MeSH term]"). Results: Twenty-four articles (n = 888) were included, with the resulting conclusions demonstrating that ESWT was effective for knee OA compared with sham ESWT; however, ESWT was not effective for patients with severe knee OA. Patients receiving higher energy or higher shock number had significant improvement than those receiving lower energy or less shock number, respectively. Adding ESWT in isokinetic muscular strengthening exercises (IMSE) was more effective than IMSE alone. The efficacy of ESWT was better than other therapies, including intravenously applied prostacyclin and bisphosphonate, corticosteroid injection, kinesiotherapy, hyaluronic acid injection, platelet-rich plasma injection, and physiotherapy. Conclusions: This review demonstrated that ESWT was effective for knee OA. Higher energy and more shock numbers could obtain better efficacy. ESWT could be used as a replacement for some other therapies.

Is Shock Wave Application Effective on Various Chronic Wounds in the Geriatric Population? Preliminary Clinical Study.

Purpose: Extracorporeal shock wave therapy (ESWT) is a beneficial adjunct modality for chronic wounds. Limited research has been conducted on pressure ulcers (PUs), while the majority of studies have focused on diabetic foot ulcers (DFUs) and venous leg ulcers (VLUs). This study aimed to evaluate the short-term effects of radial ESWT in older adults with chronic wounds. Patients and Methods: This study involved a total of 31 wounds: PUs (n=22), VLUs (n=7), and DFUs (n=2). A single radial ESWT was performed with 300 + 100 shocks per cm2, pressure of 2.5 bar, energy of 0.15 mJ/mm2, and frequency of 5 Hz. Assessments using digital planimetry and clinical methods, utilizing the Wound Bed Score (WBS) and the Bates-Jansen Wound Assessment Tool (BWAT) were performed before the radial ESWT application (M0) and one week after (M1). Results: A significant wound decrease in planimetry was noted (pre-ESWT vs post-ESWT), with wound area from 9.4 cm2 to 6.2 cm2, length from 6.4 cm to 3.9 cm, and width from 2.8 cm to 2.1 cm (p<0.001). Additionally, a substantial clinical improvement was noted in both the WBS with a 31.25% increase and the BWAT with a 20.00% increase (p<0.001). It was also found a significant correlation between the planimetric and clinical outcomes for both tools: WBS (r=-0.446, p=0.012) and BWAT (r=0.327, p=0.073). Conclusion: The ESWT application yields substantial immediate clinical effects that support the healing of chronic wounds in older adults. Even a single ESWT session can prove to be clinically effective and beneficial in the management of chronic wounds.

Current treatment options for erectile dysfunction in kidney transplant recipients.

INTRODUCTION: Erectile dysfunction (ED) and kidney dysfunction share common risk factors linked to conditions involving endothelial impairment, such as coronary artery disease, dyslipidemia, diabetes mellitus, hypertension, smoking, and obesity. Men with chronic kidney disease experience a high incidence and prevalence of ED. While a functional renal graft can alleviate the issue for some patients, a significant portion of recipients still experience ED (20%-50%). OBJECTIVES: This narrative review describes the variety of current treatments modalities on ED in kidney transplant recipients (KTRs) and their clinical outcomes. METHODS: MEDLINE, Web of Science, PubMed, and Google Scholar were used to find eligible articles pertaining to the treatment options of ED in KTRs. A total of 64 articles were evaluated. RESULTS: In KTRs, ED stems from a multifaceted etiology: anxiety, drug side effects, interference with penile vascularity, or the response of cavernosal muscle to neurotransmitters, along with changes in the endocrine milieu. A diverse range of treatments to restore erectile function has proven to be safe and effective for KTRs. Options include drug therapy, surgical interventions, intracavernosal injection therapies, vacuum erection devices, and extracorporeal shockwave therapy. CONCLUSION: The initial treatment approach may involve the use of a phosphodiesterase type 5 inhibitors at a low dosage, especially if testosterone-circulating levels align with the diagnosis of hypogonadism. The consideration of a combination therapy involving testosterone and phosphodiesterase type 5 inhibitors should be contemplated due to the associated beneficial effects. Extracorporeal shockwave therapy has shown positive short-term clinical and physiological effects on erectile function in patients who did not respond to first-line treatments, resulting in spontaneous erections sufficient for sexual penetration in 50% of cases. Penile implants should be considered as third-line options based on specific patient needs and compliance with clinical conditions.
