Woo, I., Park, J. J., Seok, H. G.
Journal of clinical medicine. 2023;12(15)
Abstract
The appropriate surgical management of osteochondral lesions of the talus (OLT) remains a challenge for foot and ankle surgeons. Currently, microfracture (MF) is the first-line operative treatment for small osteochondral lesions. However, the fibrous cartilage regenerated after MF is mechanically inferior to hyaline cartilage regeneration and is susceptible to deterioration over time. Thus, this meta-analysis aimed to elucidate the efficacy of platelet-rich plasma (PRP) augmentation compared with MF only or other adjuvant supplementations combined with the PRP + MF group (others) for the management of OLT. We searched the PubMed, Embase, Web of Science, and Cochrane Library databases for studies that compared the clinical outcomes of patients who underwent MF only and those who underwent PRP or other adjuvant materials such as hyaluronic acid or BST-CarGel. After the screening, four randomized controlled trials and one quasi-randomized controlled trial were included in this review. We used the following tools for clinical evaluation: the American Orthopedic Foot and Ankle Society (AOFAS) score, Ankle-Hindfoot Scale score, Visual Analog Scale (VAS) score for pain, and the Foot and Ankle Ability Measure (FAAM) score. The standardized mean difference (SMD) was used to analyze the differences in outcomes between groups. Patients in the PRP + MF group had superior final VAS and AOFAS scores to the MF only group. (both p < 0.01) However, no significant improvements between baseline and final follow-up were noted in either score. In addition, there was no remarkable difference in the overall FAAM pain measures between the two groups. The PRP + MF and others groups revealed no significant effect differences in the clinical scores. The results of this analysis suggest that PRP + MF would be more favorable and effective than MF only or additional adjuvant supplementation.

Abstract
BACKGROUND/OBJECTIVE To analyze the efficacy and safety after the application of platelet-rich-plasma (PRP) as an adjuvant in arthroscopic rotator cuff repairs. MATERIALS-METHODS A bibliographic search of the literature of prospective studies with level of evidence one or two was carried out from January 2004 to December 2021, including studies that compare the functional and re-tear results after arthroscopic cuff repair. rotator with or without PRP. RESULTS A total of 281 articles were identified, of which 14 met the inclusion criteria. The overall re-rupture rate was 24%. In the PRP group, a decrease in the re-rupture rate and better functional results were demonstrated, although these differences were not significant. CONCLUSIONS Adjuvant treatment with PRP has shown promising results, although there is not yet enough evidence to provide a clear advantage for routine use in clinical practice.

Abstract
OBJECTIVE Basic scientific studies have demonstrated positive effects of platelet-rich therapies, such as platelet-rich plasma (PRP) and platelet-rich fibrin (PRF), on tendon repair. However, clinical evidence indicating improved prognosis is controversial. In this study, we aimed to determine whether augmentation of arthroscopic rotator cuff repair with PRP and PRF improves outcomes compared to arthroscopic repair alone. LITERATURE SURVEY PubMed, Embase and Cochrane library databases were comprehensively searched for randomized controlled trials (RCTs) published until June 2022 according to the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) guidelines. No language restriction was applied. METHODOLOGY The primary outcomes were the rate of repeat tears after arthroscopic rotator cuff repair (retear rate) and clinical function scores (Constant-Murley score, University of California, Los Angeles score), and the extracted data were assessed for quality. Statistical analyses were performed using Review manager 5.3, and P < 0.05 was considered statistically significant. SYNTHESIS Ten RCTs with 628 patients were included. The results showed that augmenting surgery with PRP reduces retear rates compared to surgery alone (risk ratio [RR] = 0.40, 95% confidence interval [CI] [0.23, 0.69], P = 0.001), whereas PRF has no effect on retear rates (P = 0.92). Regarding clinical function, PRP improves constant scores (mean difference [MD] = 2.03, 95% CI [0.13, 3.93], P = 0.04) and University of California, Los Angeles scores (MD = 1.30, 95% CI [0.36, 2.24], P = 0.007), whereas PRF only improves constant scores (MD = 3.93, 95% CI [1.50, 6.36], P = 0.002). However, these differences were small and below the minimum clinically important difference threshold. CONCLUSIONS This study showed that compared to arthroscopic rotator cuff repair alone, the application of PRP in arthroscopic rotator cuff repair reduces retear rate and improves clinical function scores, whereas the application of PRF has no clinically meaningful benefit. The small number and heterogeneity of studies as well as methodological limitations and risk of bias limit confidence in the true effect. This article is protected by copyright. All rights reserved.

Foot and ankle surgery : official journal of the European Society of Foot and Ankle Surgeons. 2023
Abstract
BACKGROUND To systematically evaluate the efficacy of arthroscopic microfracture surgery combined with platelet-rich plasma (PRP) injection in treating osteochondral lesions of talus (OLT). METHOD A computer-based search of the PubMed, EMbase, Cochrane Library was developed. The search time was dated in December 2022. Randomized controlled trials and prospective case control studies comparing the treatment of OLT with microfracture surgery combined with PRP injection and microfracture surgery alone were included. The quality of the literatures were evaluated. Meta analysis was completed using the data of postoperative pain and function scores of the ankle joint reported in the literature. RESULTS Five randomized controlled trials with a total of 198 patients were included. Compared with microfracture surgery alone, meta-analysis showed that the postoperative visual analogue scale (VAS) score for ankle pain was significantly lower (P < 0.001), and the American Orthopaedic Foot and Ankle Society score (AOFAS) was significantly better ( P < 0.001) in the group of microfracture surgery combined with PRP injection. The change of VAS and AOFAS was also significantly better in the group of microfracture surgery combined with PRP injection (P < 0.001). CONCLUSION Arthroscopic microfracture surgery combined with PRP injection in treating OLT can significantly reduce pain and improve ankle function. More long-term follow-up, high-quality studies are needed. LEVEL OF EVIDENCE II.

BMC musculoskeletal disorders. 2023;24(1):366
Abstract
PURPOSE To systematically review the studies regarding to the safety, efficacy and application methods of PRP in promoting the talar cartilage repair. METHODS A systematic review was performed by searching PubMed, Web of Science, OVID and EMBASE to identify studies that compared the clinical efficacy of PRP for talar cartilage repair. Main outcome was the American Orthopedic Foot and Ankle Society (AOFAS) score for function and Visual Analog Scale (VAS) for pain was the second outcome. RESULTS A total of 10 studies were included in this systematic review, including 4 randomized controlled trials, 1 controlled trial, 3 case series and 2 cohort studies. Four RCTs were analyzed using meta-analysis. For all outcomes, statistical results favored PRP group (AOFAS MD = 7.84; 95% CI= [-0.13, 15.80], I(2) = 83%, P < 0.01; VAS: MD = 1.86; 95% CI= [0.68, 3.04], I(2) = 85%, P < 0.01). There were almost no reports of adverse events related to PRP intervention. Subgroup analysis showed that whether PRP was used alone or combined with other treatments could result in high heterogeneity but no more specific factors were identified to contribute to this. CONCLUSION PRP is safe and effective for talar cartilage repair. In addition to the standardization of PRP preparation and application, it is necessary to distinguish the effects of PRP used alone or in combination with other treatments. In PRP studies, surgical treatment of talar cartilage repair remains the mainstream. The regulation of PRP in surgical applications are worth exploring. The most relative component is the mesenchymal stem cell because it is the only exposed chondrocyte precursor in the articular cavity whether it is microfracture or cell transplantation. TRIAL REGISTRATION The study was registered in the PROSPERO International prospective register of systematic reviews (CRD42022360183).

Yang, B., Ma, J.
International journal of rheumatic diseases. 2023
Abstract
OBJECTIVE To assess the efficacy and safety of arthroscopic surgery associated with platelet-rich plasma (PRP) infusion in treating knee osteoarthritis (KOA). METHODS PubMed, EMBASE, ScienceDirect, Cochrane Library, China Knowledge Network Database, China VIP Database, Wanfang Database, and China Biomedical Literature Database online database were searched for the case-control trial of arthroscopic surgery associated with PRP infusion in patients with KOA. During the search period of January 2010 through May 2022, two researchers independently extracted the data. With RevMan5.3, we performed a meta-analysis on the collected data. RESULTS A total of six clinical controlled studies were included, including 333 individuals. Compared with the control group treated only by arthroscopic surgery, the results showed that the visual analogue scores of patients in the arthroscopic surgery and PRP infusion group were significantly lower at 3, 6 and 12 months after operation, and the Western Ontario and McMaster Universities Osteoarthritis Index were significantly lower at 3, 6 and 12 months after operation (p < .05). The meta-analysis of Hospital for Special Surgery (HSS) knee score and Lisum knee score (LKSS) showed that postoperative HSS score, LKSS score at 3, 6, and 12 months after operation, and SF-36 quality of life score at 6 and 12 months after operation were higher (p < .05). CONCLUSION Arthroscopic debridement associated with PRP is more successful in relieving knee pain and enhancing knee joint function than arthroscopic debridement in treating KOA. The treatment scheme deserves to be popularized in clinical practice, but further research and longer interventions will be needed to validate it, using high-quality methods.

Effects of Platelet-Rich Plasma on Clinical Outcomes After Anterior Cruciate Ligament Reconstruction: A Systematic Review and Meta-analysis
Zhu T, Zhou J, Hwang J, Xu X
Orthopaedic journal of sports medicine. 2022;10(1):23259671211061535
Abstract
BACKGROUND Many studies have documented the use of platelet-rich plasma (PRP) alongside anterior cruciate ligament (ACL) reconstruction (ACLR) in the management of ACL injury, but evidence on the benefits of PRP in improving the clinical outcomes of ACLR is inconsistent. PURPOSE To help in our understanding, we undertook a systematic review and meta-analysis of randomized controlled trials (RCTs) that evaluated the effects of PRP on patient-reported functional scores, the clinical assessments of knee function and structure, and complications. STUDY DESIGN Systematic review; Level of evidence, 1. METHODS We searched 9 online databases for RCTs published in English or Chinese that examined the effects of PRP on ACLR. The primary outcome measures were visual analog scale (VAS) for pain and International Knee Documentation Committee (IKDC) scores. The secondary outcomes included KT-1000 arthrometer, pivot-shift test, Lysholm and Tegner scores, tunnel widening, graft characterization, and complications. Subgroup analyses were performed according to time of assessments. Fixed- and random-effects models were selected for data analysis. RESULTS A total of 14 studies were included. When PRP was injected to graft tunnels, the pooled VAS scores of the 2 groups were similar (P = .31), and the subgroup analysis found that VAS and IKDC only improved at 3 months postoperatively (P = .0003 and P < .00001, respectively). When PRP was used at the bone-patellar tendon-bone harvest sites, VAS was decreased in the first 6 months postoperatively (P < .00001), whereas IKDC score was not remarkably different (P = .07). After PRP injection, Lysholm scores at 3 months postoperatively was different between the 2 groups (P < .00001), but the Tegner scores (P = .86), KT-1000 measurements (P = .12), the positive rate of pivot-shift test (P = .64), the enlargement of tunnels (femoral, P = .91; tibial, P = .80), and the characterization of grafts (P = .05) were not different. No difference in complications was found in either group. CONCLUSION PRP applied alongside ACLR could reduce postoperative pain and improve knee function in the short and medium terms but is ineffective in the long term. PRP does not improve knee stability and the enlargement of tunnels and does not accelerate the healing of grafts. Further studies would be required.

Effectiveness of Platelet-Rich Plasma in Anterior Cruciate Ligament Reconstruction: A Systematic Review of Randomized Controlled Trials
Cao Y, Wan YD
Orthopaedic surgery. 2022
Abstract
This study aimed to identify the effectiveness of platelet-rich plasma (PRP) for patients operated with anterior cruciate ligament reconstruction (ACLR). Databases of PubMed, Embase, and CENTRAL were independently retrieved by two authors, for identifying the eligible randomized controlled trials (RCTs) comparing the clinical and imaging outcomes of ACL reconstructed patients augmented with or without PRP. The Cochrane Collaboration tool was utilized to assess the risk of bias of the included trials. We qualitatively synthesized the outcomes include the image evaluations on the healing of bone tunnels, graft remodeling, donor site healing and tunnel widening, and clinical evaluations on knee stability and function, pain symptom by visual analogue scale (VAS), inflammatory parameters and so on. A total of 16 RCTs, including 1025 patients, were included for eligibility. Generally, the included studies were of low risk of bias, but the conducting of allocation concealment was not clearly described in many studies. Three imaging techniques, including MRI, CT and ultrasound, were selected in these trials. Significant improvement on graft remodeling, bone tunnel healing, harvest site healing and bone tunnel diameters were demonstrated in one of five (20.0%), three of five (60.0%), two of four (50.0%) and one of five (20.0%) studies respectively, for PRP group. Various clinical outcomes, such as IKDC score, Lysholm score, Tegner score, knee anteroposterior and rotational laxity, range of motion and VAS, could not be improved with PRP application. The PRP is associated with very limited role in improving knee outcomes following ACLR, and there is no indication for PRP procedures in ACLR at this stage.

International journal of sports medicine. 2022
Abstract
To systematically review of randomized controlled trials(RCTs) to compared the effects of leukocyte-rich and leukocyte-poor platelet-rich plasma in arthroscopic rotator cuff repair. Two independent reviewers comprehensively searched PubMed, Embase, and Cochrane library databases according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Comparison of leukocyte-rich platelet-rich plasma or leukocyte-poor platelet-rich plasma in rotator cuff repair in a level I RCTs. Methodological quality assessment was carried out using Cochrane Review Manager 5.3 software. P<0.05 was considered statistically significant. Nine RCTs with 540 patients were included in this review. Meta-analysis showed that leukocyte-poor platelet-rich plasma in significantly reduced retear rate in rotator cuff repair [RR=0.56 95%CI (0.42,0.75); P＜0.05), and in clinical results, the constant score [MD=3.67, 95%CI (1.62,5.73); P=0.0005], UCLA score [MD=1.60, 95%CI (0.79,2.42); P=0.0001], ASES score [MD=2.16, 95%CI(0.12,4.20);P=0.04] were significantly improved. There was a significant result in favor of PRP for the Constant score [MD=-1.24, 95%CI(-1.50,-0.99); P＜0.00001], while SST scores were not significantly different among all groups [MD=0.21, 95%CI(-0.21,0.64); P=0.32]. In conclusion, leukocyte-poor platelet-rich plasma can improved the clinical function and reduced retear rate in arthroscopic rotator cuff repair. In contrast, the efficacy of leukocyte-rich platelet-rich plasma was not significantly improved with the exception of VAS score.

Time to Total Knee Arthroplasty after Intra-Articular Hyaluronic Acid or Platelet-Rich Plasma Injections: A Systematic Literature Review and Meta-Analysis
Berkani S, Courties A, Eymard F, Latourte A, Richette P, Berenbaum F, Sellam J, Louati K
Journal of clinical medicine. 2022;11(14)
Abstract
Intra-articular (IA) hyaluronic acid (HA) and platelet-rich plasma (PRP) injections are increasingly being prescribed for knee osteoarthritis (KOA). However, failure of the medical treatment may result in total knee arthroplasty (TKA). We wondered if IA HA or PRP injections (intervention) may delay the time to TKA (outcome) among KOA patients (population), compared to KOA patients not receiving these injections (comparator). For this systematic literature review (SLR) and meta-analysis, we selected observational studies with at least one group of patients receiving IA HA or PRP and with TKA data available. The main outcome was time from the diagnosis of KOA to TKA. We included 25 articles in the SLR (2,824,401 patients) and four in the meta-analysis. The mean strengthening the reporting of observational studies in epidemiology (STROBE) score was 63%. For patients receiving versus not receiving HA injections, the delay between a declared diagnosis of KOA to TKA was increased by 9.8 months (95% CI (8.2-11.4)). As compared with standard of care, the effect size of HA injections for this outcome was 0.57 (95% CI (0.36-0.76)). Only one study described a median time from PRP injections to TKA of 4.1 years (range 0.3-14.7). IA HA injections were associated with increased time to TKA. Causality cannot be concluded because of missing confounder factors as comorbidities. Data were insufficient to conclude any effect of PRP injections on TKA delay.
