  • Ultrasound-Guided Percutaneous Injection, Hydrodissection, and Fenestration for Carpal Tunnel Syndrome: Description of a New Technique

    Abstract

    Objective: Carpal tunnel syndrome, caused by compression of the median nerve deep to the flexor retinaculum, is the most common entrapment neuropathy. Most patients are initially treated with conservative mea-sures such as splinting. When conservative measures fail, interventional techniques are considered the next step. Many studies have appeared comparing open surgical flexor retinaculum release to blind injections of corticosteroids into the carpal tunnel, but neither technique has proven superior to the other. Advantages of injection are: lower level of invasiveness, faster recovery, and ease of the technique. Occasional failures and complications occur with all techniques.

    Conclusion: Ultrasound-guided hydrodis section and fenestration is a viable, easy, relatively non-invasive therapy for carpal tunnel syndrome that can result in pro longed symptom relief, and may be a way to postpone, or even obviate the need for, open release.

  • Assesing the cytokine content of human platelet-rich plasma

    Abstract

    Human platelet-rich plasma (PRP) is plasma that is enriched with thrombocytes at a concentration of 1000 * 109 per litre, higher than normal (150 - 350 * 109 per litre). Thrombocytes are known to contain growth factors including IGF, PDGF, EGF, FGF, TGF-li, PDEGF, VEGF or PDAF as well as thrombospondin and osteonectin. The release of these growth factors is induced by thrombocyte activation resulting from their exposure to a variety of substances such as thrombin, Calciom chloride or collagen. Growth factors are found in higher concentrations in PRP than in blood, and could be used to facilitate wound healing at a faster rate. Currently, PRP is employed in dentistry, dermatology, traumatology and orthopedics. In developed countries, PRP is also actively used in treating acute and chronic skin lesions. Though commercial devices for clinical preparation of autologous PRP are available, standardized PRP-preparation protocols are yet to be developed. Furthermore, only a handful of research work is aimed at optimizing methods of obtaining platelet-rich plasma. Therefore, two different modifications of the Araki et al method, the most standardized of all available methods, were used to prepare high cytokine-containing platelet-rich plasma.

  • Effects of ozone therapy on facial nerve regeneration

    Abstract

    Introduction: Ozone may promote moderate oxidative stress, which increases antioxidant endogenous systems. There are a number of antioxidants that have been investigated therapeutically for improving peripheral nerve regeneration. However, no previous studies have reported the effect of ozone therapy on facial nerve regeneration.

    Objective: We aimed to evaluate the effect of ozone therapy on facial nerve regeneration.

    Methods: Fourteen Wistar albino rats were randomly divided into two groups with experimental nerve crush injuries: a control group, which received saline treatment post-crush, and an experimental group, which received ozone treatment. All animals underwent surgery in which the left facial nerve was exposed and crushed. Treatment with saline or ozone began on the day of the nerve crush. Left facial nerve stimulation thresholds were measured before crush, immediately after crush, and after 30 days. After measuring nerve stimulation thresholds at 30 days post-injury, the crushed facial nerve was excised. All specimens were studied using light and electron microscopy.

    Results: Post-crushing, the ozone-treated group had lower stimulation thresholds than the saline group. Although this did not achieve statistical significance, it is indicative of greater functional improvement in the ozone group. Significant differences were found in vascular congestion, macrovacuolization, and myelin thickness between the ozone and control groups. Significant differences were also found in axonal degeneration and myelin ultrastructure between the two groups.

    Conclusions: We found that ozone therapy exerted beneficial effect on the regeneration of crushed facial nerves in rats.

  • Hypertonic dextrose injections (prolotherapy) in the treatment of symptomatic knee osteoarthritis: A systematic review and meta-analysis

    Abstract

    Hypertonic dextrose injections (prolotherapy) is an emerging treatment for symptomatic knee osteoarthritis (OA) but its efficacy is uncertain. We conducted a systematic review with meta-analysis to synthesize clinical evidence on the effect of prolotherapy for knee OA. Fifteen electronic databases were searched from their inception to September 2015. The primary outcome of interest was score change on the Western Ontario and McMaster Universities Arthritis Index (WOMAC). Three randomized controlled trials (RCTs) of moderate risk of bias and one quasi-randomized trial were included, with data from a total of 258 patients. In the meta-analysis of two eligible studies, prolotherapy is superior to exercise alone by a standardized mean difference (SMD) of 0.81 (95% CI: 0.18 to 1.45, p = 0.012), 0.78 (95% CI: 0.25 to 1.30, p = 0.001) and 0.62 (95% CI: 0.04 to 1.20, p = 0.035) on the WOMAC composite scale; and WOMAC function and pain subscale scores respectively. Moderate heterogeneity exists in all cases. Overall, prolotherapy conferred a positive and significant beneficial effect in the treatment of knee OA. Adequately powered, longer-term trials with uniform end points are needed to better elucidate the efficacy of prolotherapy.

  • Hypertonic dextrose injection (prolotherapy) for knee osteoarthritis: Long term outcomes

    Abstract

    Objective: Knee osteoarthritis (OA) is a common, debilitating chronic disease. Prolotherapy is an injection therapy for chronic musculoskeletal pain. Recent 52-week randomized controlled and open label studies have reported improvement of knee OA-specific outcomes compared to baseline status, and blinded saline control injections and at-home exercise therapy (p<0.05). However, long term effects of prolotherapy for knee OA are unknown. We therefore assessed long-term effects of prolotherapy on knee pain, function and stiffness among adults with knee OA.

    Design: Post clinical-trial, open-label follow-up study.

    Setting: Outpatient; adults with mild-to-severe knee OA completing a 52-week prolotherapy study were enrolled.

    Intervention And Outcome Measures: Participants received 3-5 monthly interventions and were assessed using the validated Western Ontario McMaster University Osteoarthritis Index, (WOMAC, 0-100 points), at baseline, 12, 26, 52 weeks, and 2.5 years.

    Results: 65 participants (58

  • Effectiveness and relevant factors of platelet?rich plasma treatment in managing plantar fasciitis: A systematic review

    Abstract

    Background: Plantar fasciitis (PF) is a common foot complaint, affects both active sportsmen and physically inactive middle age group. It is believed that PF results from degenerative changes rather than inflammation. Platelet?rich plasma (PRP) therapy has been introduced as an alternative therapy for PF. This study is aimed to systematically review to the effectiveness and relevant factors of PRP treatment in managing PF. Materials and Methods: A search was conducted in electronic databases, including PubMed,Scopus, and Google Scholar using different keywords. Publications in English?language from 2010 to 2015 were included. Two reviewers extracted data from selected articles after the quality assessment was done. Results: A total of 1126 articles were retrieved,but only 12 articles met inclusion and exclusion criteria. With a total of 455 patients, a number of potentially influencing factors on the effectiveness of PRP for PF was identified. In all these studies, PRP had been injected directly into the plantar fascia, with or without ultrasound guidance. Steps from preparation to injection were found equally crucial. Amount of collected blood, types of blood anti?coagulant, methods in preparing PRP, speed, and numbers of time the blood samples were centrifuged, activating agent added to the PRP and techniques of injection, were varied between different studies. Regardless of these variations, superiority of PRP treatment compared to steroid was reported in all studies. Conclusion: PRP therapy might provide an effective alternative to conservative management of PF with no obvious side effect or complication. The onset of action after PRP injection also greatly depended on the degree of degeneration.

  • The Efficacy of Platelet-Rich Plasma in the Treatment of Rib Fractures.

    Abstract

    Background: €ƒRib fracture is the most common result of thoracic traumas. Intrapulmonary shunt, alveolar capillary membrane damage, intra-alveolar hemorrhage, and hypoxia may develop following rib fractures. Therefore, prompt treatment is important. The aim of this experimental study was to analyze the effects of platelet-rich plasma (PRP) on rib fractures to secure a speedier and more efficient treatment method. Materials and Methods €ƒThe study involved 18 New Zealand white rabbits, randomly divided into three groups as Group 1, the sham group with no surgical intervention; Group 2, the control group in which simple rib fractures were applied and no treatment; and Group 3, in which rib fractures were applied and then PRP treatment was administered. Results €ƒThe mean recovery plate thickness measurements were found to be statistically significantly higher in the PRP group compared with the other groups (p < 0.005). A thicker fibrotic cell proliferation and the formation of many capillaries were observed around the growth plate in the PRP group compared with the other groups. These structures were lesser in the control group compared with the PRP group and at the lowest level in the sham group. Larger and distinct callus formation was observed and a new intramedullary field in the PRP group. Conclusions €ƒPRP is a reliable and effective autologous product with minimal side effects, which can be considered as an alternative treatment in patients with rib fractures and used easily in pseudoarthrosis, surgical fracture, or flail chest.

  • Platelet-rich Plasma and Bone Marrow-derived Mesenchymal Stem Cells in Sports Medicine

    Abstract

    Regenerative medicine is a fast-growing field in orthopedic sports medicine. Platelet-rich plasma contains multiple factors that have been shown to augment healing, thereby stimulating its use in multiple areas of acute and chronic injuries. Mesenchymal stem cells have pluripotent potential to form into tissues pertinent to orthopedics, such as cartilage and bone. As such, there is been a surge in the research directed toward steering those stem cells into a particular lineage as part of treatment for a variety of soft-tissue, cartilage, and bone pathologies. Overall, there are promising reports of their potential success, but there is a need for continued investigation into the efficacy of platelet-rich plasma and stem cells in sports medicine.

  • Efficacy of Platelet-Rich Plasma versus Hyaluronic Acid for treatment of Knee Osteoarthritis: A systematic review and meta-analysis

    Abstract

    Introduction: Knee osteoarthritis is a very common chronic degenerative disease that could impose significant costs to the health system. Although osteoarthritis can affect all joints, knee osteoarthritis is the most common type among adolescents. Non-surgical treatments include corticosteroids injection, hyaluronic acid, and platelet-rich plasma. The aim of this study was to investigate the efficiency of platelet-rich plasma versus hyaluronic acid for the treatment of knee osteoarthritis.

    Methods: Pubmed, Cochran library, Scopus and Ovid databases were investigated to identify related studies from 2000 through August 2015. To study the efficiency, Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) outcome using the Standard Mean Difference (SMD) index was calculated using a random model and a confidence interval of 95%. In addition, sensitivity and cumulative analysis were conducted. The data were analyzed using RevMan 5.3.5 and Stata 12 software.

    Results: Seven studies with 722 subjects (364 participants in PRP and 358 participants in the HA group) were analyzed. The WOMAC PRP compared to HA, SMD = −0.75 (95% CI: −1.33 to −0.18, I2 = 92.6%) in treatment of knee osteoarthritis was statistically significant and PRP was more effective.

    Conclusion: The results of this meta-analysis two years after PRP injection showed the efficacy of PRP versus HA. However, further studies are required to determine the longer-term effects.

  • Good prognosis factors after a platelet rich plasma (PRP) injection for tendinopathies ?

    Abstract

    Introduction : Platelet-rich plasma injections are a recent treatment for chronic tendinopathies. However, this theraeutic remains controversed in litterature. Up to now, there is no prognosis factors identified to predict a good evolution after injection of PRP.

    Purpose: The aims of this study were to evaluate the effect of PRP injection followed by a standardized reeducation protocol among patients suffering from different tendinopathies and to determine the good prognosis factors, if any.

    Methods : 51 patients suffering from different tendinopathies and refractory to conventional physiotherapy were treated with a PRP injection. Prior to the injection, a blood sample was drawn and some biological parameters (glycemia, cholesterol level, ...). A pain assessment was then made using a visual analog scale (VAS) and a pressure algometer. The same assessment was carried out after 6 weeks and 12 weeks when possible.

    Results : There is an overall significant improvement VAS score at the end of the 12 weeks follow- up. However, no correlation was found between the evolution of the clinical scores and the biological parameters measured.

    Discussion and Conclusions : A PRP injection followed by a program of eccentric rehabilitation positively affects the algo-functional scores of patients with tendinopathie who were refractory to conventional physiotherapy, whatever their initial biological parameters.

  • Does platelet-rich plasma decrease time to return to sports in acute muscle tear? A randomized controlled trial

    Abstract


    Purpose: The aim of this study is to report the effects of autologous PRP injections on time to return to play and recurrence rate after acute grade 2 muscle injuries in recreational and competitive athletes.


    Methods: Seventy-five patients diagnosed with acute muscle injuries were randomly allocated to autologous PRP therapy combined with a rehabilitation programme or a rehabilitation programme only. The primary outcome of this study was time to return to play. In addition, changes in pain severity and recurrence rates were evaluated.


    Results: Patients in the PRP group achieved full recovery significantly earlier than controls (P = 0.001). The mean time to return to play was 21.1 ± 3.1 days and 25 ± 2.8 days for the PRP and control groups, respectively (P = 0.001). Significantly lower pain severity scores were observed in the PRP group throughout the study. The difference in the recurrence rate after 2-year-follow-up was not statistically significant between groups.


    Conclusions: A single PRP injection combined with a rehabilitation programme significantly shortened time to return to sports compared to a rehabilitation programme only. Recurrence rate was not significantly different between groups.

  • Mesenchymal stem cells (MSCs) as skeletal therapeutics-an update

    Abstract

    Mesenchymal stem cells hold the promise to treat not only several congenital and acquired bone degenerative diseases but also to repair and regenerate morbid bone tissues. Utilizing MSCs, several lines of evidences advocate promising clinical outcomes in skeletal diseases and skeletal tissue repair/regeneration. In this context, both, autologous and allogeneic cell transfer options have been utilized. Studies suggest that MSCs are transplanted either alone by mixing with autogenous plasma/serum or by loading onto repair/induction supportive resorb-able scaffolds. Thus, this review is aimed at highlighting a wide range of pertinent clinical therapeutic options of MSCs in the treatment of skeletal diseases and skeletal tissue regeneration. Additionally, in skeletal disease and regenerative sections, only the early and more recent preclinical evidences are discussed followed by all the pertinent clinical studies. Moreover, germane post transplant therapeutic mechanisms afforded by MSCs have also been conversed. Nonetheless, assertive use of MSCs in the clinic for skeletal disorders and repair is far from a mature therapeutic option, therefore, posed challenges and future directions are also discussed. Importantly, for uniformity at all instances, term MSCs is used throughout the review.

  • Choice of intra-articular injection in treatment of knee osteoarthritis: platelet-rich plasma, hyaluronic acid or ozone options

    Abstract

    Purpose: This study was performed to compare the efficacy of treatment in three groups of patients with knee osteoarthritis (OA) given an intra-articular injection of platelet-rich plasma (PRP), hyaluronic acid (HA) or ozone gas.

    Methods: A total of 102 patients with mild-moderate and moderate knee OA who presented at the polyclinic with at least a 1-year history of knee pain and VAS score ≥4 were randomly separated into three groups. Group 1 (PRP group) received intra-articular injection of PRP ×— 2 doses, Group 2 (HA group) received a single dose of HA, and Group 3 (Ozone group) received ozone ×— four doses. Weight-bearing anteroposterior-lateral and Merchant\'s radiographs of both knees were evaluated. WOMAC and VAS scores were applied to all patients on first presentation and at 1, 3, 6 and 12 months.

    Results: At the end of the 1st month after injection, significant improvements were seen in all groups. In the 3rd month, the improvements in WOMAC and VAS scores were similar in Groups 1 and 2, while those in Group 3 were lower (p < 0.001). At the 6th month, while the clinical efficacies of PRP and HA were similar and continued, the clinical effect of ozone had disappeared (p < 0.001). At the end of the 12th month, PRP was determined to be both statistically and clinically superior to HA (p < 0.001).

    Conclusion: In the treatment of mild-moderate knee OA, PRP was more successful than HA and ozone injections, as the application alone was sufficient to provide at least 12 months of pain-free daily living activities.
