Clinics (Sao Paulo, Brazil). 2021;76:e2355
OBJECTIVES To evaluate the efficacy of autologous platelet-rich plasma (PRP) gel in the treatment of refractory pressure injuries and its effect on wound healing time and quality of life of patients. METHODS A random number table method was used to group 102 patients with refractory pressure injuries into either a control group (CG) (51 cases) receiving negative pressure wound therapy (NPWT) or a study group (SG) (51 cases) receiving NPWT+PRP gel. RESULTS The total efficacy rate in the SG (92.16%) was higher than that in the CG (76.47%) (p<0.05). The SG exhibited lower visual analog scale (VAS) scores and pressure ulcer scale for healing (PUSH) scores, smaller wound sizes and depths, and shorter wound healing times than the CG after 21 days of treatment (p<0.05). After 6 months of treatment, the SG scored higher than the CG on the psychological, physiological, social functions, and daily activity domains on the World Health Organization Quality of Life (WHOQOL-BREF) scale (p<0.05). The incidence of postoperative complications in the SG (13.73%) was not significantly different from that of the CG (7.84%) (p>0.05). CONCLUSION In the treatment of refractory pressure injuries, PRP gel can accelerate wound healing, reduce wound pain, shorten the treatment cycle, regulate tissue inhibitor matrix metalloproteinase-1 (TIMP-1) and matrix metalloproteinase-9 (MMP-9) levels and the expression of specific proteins in granulation tissue, reduce the levels of the inflammatory factors interleukin-1β (IL-1β), IL-8, and tumor necrosis factor-α (TNF-α), and improve the quality of life of patients without increasing complications.
Clinical studies on platelet-rich plasma (PRP) therapy for chronic cutaneous ulcers: a systematic review and meta-analysis of randomized controlled trials
Advances in wound care. 2021
SIGNIFICANCE Platelet-rich plasma (PRP) may be a potential drug for treatment of chronic refractory ulcers, which increase the risk of systemic infection and local canceration. However, the efficacy and safety of clinical application of PRP are still controversial. Thus, this study was aimed to assess the efficacy and safety of PRP in patients with chronic ulcers. Recent Advances: For this meta-analysis, Cochrane's Library, MEDLINE, EMBASE, PubMed, and Web of Knowledge databases were searched. Results were pooled using a random-effects model. The primary outcome was the proportion of completely healed chronic ulcers. CRITICAL ISSUES Seventeen randomized controlled trials (RCTs) were included. Compared with the control group, PRP significantly increased the fraction of healed ulcers (pooled RR =1.50; 95% CI 1.20 to 1.87; I2=47.8%). In autologous PRP (APRP) and homologous PRP (HPRP) subgroups, there were statistical differences between the control group vs. treatment subgroup (pooled RR=1.30, 95% CI 1.10 to 1.54, I2=25.7%; pooled RR=3.53, 95% CI 1.94 to 6.43, I2=0.0%, respectively). In terms of percent of chronic ulcers area healed, there was a statistically significant difference between the PRP-treated group vs. the control group (SMD=1.37, 95%CI=0.91 to 1.82, I2=22.1 %). As for PRP safety, there existed a statistically significant difference between the APRP subgroup and the HPRP subgroup, respectively (pooled RR=0.58; 95% CI 0.35 to 0.98; I2=0.0%) and (pooled RR=4.12; 95% CI 1.55 to 10.96; I2=6.8%). FUTURE DIRECTIONS Our findings shows that PRP may be a beneficial treatment of chronic skin ulcers and that APRP may be much safer than HPRP.

Global spine journal. 2021;:2192568221998367
STUDY DESIGN Systematic review and meta-analysis. OBJECTIVES We performed this meta-analysis to evaluate whether intradiscal Platelet Rich Plasma(PRP) injection has any beneficial role in the management of lumbar disc disease. METHODS We conducted independent and duplicate electronic database searches including PubMed, Embase, and Cochrane Library till September 2020 for studies investigating the role of intradiscal PRP in the management of lumbar disc disease. The analysis was performed in the R platform using OpenMeta[Analyst] software. RESULTS 13 studies including 2 RCTs, 5 prospective, and 6 retrospective studies involving 319 patients were included in the meta-analysis. A single-arm meta-analysis of the included studies showed a beneficial effect of the intervention in terms of pain relief outcomes like VAS score (p < 0.001), pain component of SF-36 (p = 0.003) while such improvement was not seen in functional outcome measures like ODI score (p = 0.071), the physical component of SF-36 (p = 0.130) with significant heterogeneity noted among the included studies. No structural improvement in magnetic resonance imaging was observed (p = 0.106). No additional procedure-related adverse events were noted in the included studies (p = 0.662). CONCLUSION There is a paucity of high-quality studies to give conclusive evidence on the benefits of intradiscal PRP for lumbar disc disease. Although intradiscal PRP injection has shown some beneficial effect in controlling pain for lumbar disc disease, we could not find structural or functional improvement from the included studies. Hence, we recommend large double-blind double-arm randomized controlled studies to analyze the benefits of the intervention being analyzed.
Comparative analysis of leucocyte poor vs leucocyte rich platelet-rich plasma in the management of lateral epicondylitis: Systematic review & meta-analysis of randomised controlled trials
Journal of clinical orthopaedics and trauma. 2021;19:96-107
STUDY DESIGN Systematic Review & Meta-analysis. OBJECTIVES We aim to comparatively analyse the efficacy and safety of using leucocyte-poor platelet rich plasma (LP-PRP) against leucocyte-rich platelet rich plasma (LR-PRP) in the management of lateral epicondylitis. MATERIALS AND METHODS We conducted independent and duplicate electronic database searches including PubMed, Embase, Web of Science and Cochrane Library till September 2020 for randomised controlled trials analyzing the efficacy and safety of LP-PRP and LR-PRP in the management of lateral epicondylitis. Visual Analog Score(VAS) for pain, Disabilities of the Arm, Shoulder and Hand (DASH) Score, Patient Reported Tennis-Elbow Evaluation (PRETEE) Score, Mayo Elbow Performance Score(MEPS) and adverse events were the outcomes analyzed. Analysis was performed in R-platform using OpenMeta[Analyst] software. RESULTS We performed a single arm meta-analysis of 26 studies involving 2034 patients. On analysis it was noted that significant improvement was noted in the VAS for pain (p < 0.001), DASH score (p < 0.001), PRETEE score (p < 0.001) and MEPS (p < 0.027) compared to their pre-operative state. No significant increase in adverse events were noted compared to the control group (p = 0.170). While stratifying the results based on the type of PRP used, no significant difference was noted between the use of LP-PRP or LR-PRP in any of the above-mentioned outcome measures. CONCLUSION PRP is a safe and effective treatment option for lateral epicondylitis with clinical improvements in pain and functional scores and both types of PRP (LR-PRP & LP-PRP) offer similar results.
Platelet-Rich Plasma, Mesenchymal Stem Cell, and Non-metallic Suture-Based Fixation Technique in a Patellar Fracture Nonunion: A Technical Note and Systematic Review
Clinics in orthopedic surgery. 2021;13(3):344-351
BACKGROUD We performed a systematic review on the management of patellar fracture nonunion and report a novel suture-based non-metallic fixation technique associated with platelet-rich plasma and mesenchymal stem cell injections in the management of this injury. METHODS A systematic search was performed up to August 2020 in PubMed and Scopus electronic databases of scholarly articles evaluating different surgical techniques used for nonunion of patellar fractures, with no restrictions on language or year of publication. Furthermore, we describe our novel non-metallic suture fixation technique and a patient in whom this technique was applied. RESULTS A total of 9 articles were included in the systematic review. Tension band wiring was the most commonly used procedure (62.7%). Nonoperative procedures (8.1%) resulted in nonunion in all patients. The most common complication after open reduction and internal fixation was infection (7.8%). Our patient at the latest follow-up reported full functional recovery and full extension and flexion of the affected knee with no pain and subjectively normal strength. CONCLUSIONS The management of patella nonunions is still a challenge. The technique reported here can be used in patellar fracture nonunion, as well as in primary patellar fractures.
The Role of Autologous Platelet Concentrates in the Treatment of Medication-Related Osteonecrosis of the Jaw
The Journal of craniofacial surgery. 2021;32(2):621-625
The frequent refractory response of patients to the treatment of medication-related osteonecrosis of the jaw (MRJON) has attracted clinicians' attention to several treatments. However, they are at best, palliative, and have a higher failure rate than previous treatments. The present meta-analysis was performed to evaluate the clinical effectiveness of autologous platelet concentrates (APCs) combined with surgery in the treatment of MRONJ. The authors conducted a meta-analysis involving a systematic search of PubMed, EMBASE, Wiley Online Library and the Cochrane Library for eligible studies from their inception to November 2019, in accordance with preselected criteria. The inverse variance method was applied to fixed or random effects models based on the heterogeneity of the studies. Thirteen studies that investigated APCs in the treatment of MRONJ were eligible for inclusion in the meta-analysis of 223 patients and 33 lesions. The pooled success rate of APCs combined with surgery for MRONJ was 90% (95%CI, 80%-97%) and the pooled OR was 7.67 (95%CI, 2.10-27.98), indicating the combination was 7.67 times more effective than surgery alone. The results suggest that the use of APCs is a promising therapeutic regimen, as it provided additional benefits to surgery in the treatment of MRONJ. To achieve the benefits, a tension-free primary closure of the soft tissue is recommended as well. Randomized studies with large sample sizes is warranted to confirm our finding.
Adverse Reactions and Clinical Outcomes for Leukocyte-Poor Versus Leukocyte-Rich Platelet-Rich Plasma in Knee Osteoarthritis: A Systematic Review and Meta-analysis
Orthopaedic journal of sports medicine. 2021;9(6):23259671211011948
BACKGROUND Platelet-rich plasma (PRP) has gained attention as a therapeutic option for knee osteoarthritis; however, its efficacy varies widely. Leukocytes in PRP raise the concern of aggravating proinflammatory activity. To date, PRP has rarely been investigated with regard to leukocyte concentration. PURPOSE To provide clinical evidence of the intra-articular injection of PRPs containing different leukocyte concentrations. STUDY DESIGN Systematic review; Level of evidence, 4. METHODS We systematically searched the MEDLINE, Embase, Cochrane Library, CINAHL, and Scopus databases. PRP was classified into leukocyte-poor (LP-PRP) and leukocyte-rich (LR-PRP). Clinical outcomes including Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), visual analog scale (VAS) for pain score, International Knee Documentation Committee (IKDC) subjective score, and adverse reactions were evaluated. The Methodological Index for Non-Randomized Studies criteria were used for quality assessment. RESULTS Included were 32 studies with an evidence level between 1 and 4. Both LP-PRP and LR-PRP showed improvements above the minimal clinically important difference (MCID) in VAS pain score. No significant intergroup difference was seen at 3, 6, or 12 months of follow-up. Regarding function, both LP-PRP and LR-PRP showed improvements above the MCID in the WOMAC and IKDC scores, with no significant difference between the groups. Adverse reactions for pain were significantly higher in LR-PRP than in LP-PRP (odds ratio, 1.64; 95% confidence interval, 1.29-2.10; P = .01). After intra-articular PRP injection, LR-PRP showed a significantly higher rate of swelling than LP-PRP (odds ratio, 1.56; 95% confidence interval, 1.22-1.99; P = .02). The mean Methodological Index for Non-Randomized Studies score of the included studies was 18.6 (range, 10-24). CONCLUSION Intra-articular PRP injection resulted in improvements above the MCID in terms of pain and function in patients with knee osteoarthritis up to 12 months. The risk of local adverse reactions appeared to be increased after LR-PRP compared with LP-PRP injection. The findings of this review can support the potential use of intra-articular PRP injection for the treatment of knee osteoarthritis. In clinical application, clinicians need to consider selecting a specific type of PRP for knee osteoarthritis.

Transfusion and apheresis science : official journal of the World Apheresis Association : official journal of the European Society for Haemapheresis. 2021;:103048
OBJECTIVES To demonstrate the efficacy and safety of ultrasound guided leukocyte-rich platelet-rich plasma (LR-PRP) injection in patients with pes anserinus tendinobursitis(PATB). METHODS A prospective, randomized and single-blinded study of 60 patients with PATB were randomly assigned into 2 groups. Whereas 2 mL LR-PRP injection was applied to one grup, once accompanied by ultrasonography (USG), 2 mL LR-PRP injection was applied to the other group accompanied by USG twice with a one-week interval. Visual Analog Scale (VAS), Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), 6-minute walking test (6MWT), Likert Scale were evaluated pre-treatment, at the 4th and 12th weeks after treatment. RESULTS There was no statistical difference between the two groups in terms of age, gender, body mass index, duration of symptoms, affected side. When both groups are compared within themselves before and after treatment, there was a significant improvement in all VAS, in all WOMAC subgroups, 6MWT, at the 4th and 12th weeks after treatment. When the two groups are compared with each other, there was no statistical difference. In addition, when all patients were evaluated with Likert scale in the 12th week after treatment, complete healing in 22(36.7 %) patients, significant relief in 25(41.7 %) patients, mild relief in 4(6.7 %) patients, 5(8.3 %) same as before treatment patients, and worsened pain in 4(6.7 %) patients were seen. CONCLUSION Both single-dose and double-dose local LR-PRP is a safe and effective treatment option for patients with PATB syndrome. We believe that once LR-PRP injection may be sufficient for the treatment efficacy in PATB.
Platelet-rich plasma versus steroids injections for greater trochanter pain syndrome: a systematic review and meta-analysis
British medical bulletin. 2021
INTRODUCTION Greater trochanter pain syndrome (GTPS) is characterized by a persistent and debilitating pain around the greater trochanter. GTPS can be caused by a combination of gluteus medius or minimus tendinopathy, snapping hip or trochanteric bursitis. SOURCE OF DATA Recent published literatures identified from PubMed, EMBASE, Google Scholar, Scopus. AREAS OF AGREEMENT Platelet rich plasma (PRP) and corticosteroids (CCS) injections are useful options to manage symptoms of GTPS. AREAS OF CONTROVERSY Whether PRP leads to superior outcomes compared to CCS injections is unclear. GROWING POINTS A systematic review and meta-analysis comparing PRP versus CCS in the management of GTPS was conducted. AREAS TIMELY FOR DEVELOPING RESEARCH PRP injections are more effective than CCS at approximately 2 years follow-up.
