Abstract
BACKGROUND Rib fractures are a common traumatic injury affecting more than 350,000 patients a year. Early stabilization has shown to be effective in reducing pulmonary complications. Platelet-rich plasma (PRP) is a growth factor-rich blood product known to improve soft tissue and bone healing. We hypothesized that the addition of PRP to a rib fracture site would accelerate callus formation and improve callus strength. METHODS Platelet-rich plasma was isolated from pooled Lewis rat blood and quantified. Thirty-two Lewis rats underwent fracture of the sixth rib and were treated with 100 μL PRP (1 × 106 platelets/μL) or saline. At 2 weeks, ribs were harvested and underwent a 3-point bend, x-ray, and microcomputed tomography, and callus sections were stained with 4',6-diamidino-2-phenylindole and Alcian blue and picrosirius red. At 6 weeks, ribs were harvested and underwent a 3-point bend test, x-ray, microcomputed tomography, and Alcian blue and picrosirius red staining. RESULTS At 2 weeks, PRP increased callus diameter (9.3 mm vs. 4.3 mm, p = 0.0002), callus index (4.5 vs. 2.1, p = 0.0002), bone volume/total volume (0.0551 vs. 0.0361, p = 0.0024), cellularization (2,364 vs. 1,196, p < 0.0001), and cartilage (12.12% vs. 3.11%, p = 0.0001) and collagen (6.64% vs. 4.85%, p = 0.0087) content compared with controls. At 6 weeks, PRP increased fracture callus diameter (5.0 mm vs. 4.0 mm, 0.0466), callus index (2.5 vs. 2.0, p = 0.0466), BV/TV (0.0415 vs. 0.0308, p = 0.0358), and higher cartilage (8.21% vs. 3.26%, p < 0.0001) and collagen (37.61% vs. 28.00%, p = 0.0022) content compared with controls. At 6 weeks, PRP samples trended toward improved mechanical characteristics; however, these results did not reach significance (p > 0.05). CONCLUSION Rib fractures are a common injury, and accelerated stabilization could improve clinical outcomes. Platelet-rich plasma significantly increased callus size, calcium deposition, and cartilage and collagen content at 2 and 6 weeks and trended toward improved strength and toughness on mechanical analysis at 6 weeks compared with controls, although this did not reach significance. These findings suggest that PRP may be a useful adjunct to accelerate and improve fracture healing in high-risk patients.

Abstract
Stress fractures, a common overuse injury in physically active individuals, present a significant challenge for athletes and military personnel. Patients who sustain stress fractures have demanding training regimes where periods of rest and immobilisation have unacceptable negative consequences on sports goals and finances. Aside from being an overuse injury, there are various contributing risk factors that put certain individuals at risk of a stress fracture. The main two being nutritional deficiencies and hormonal variations, which have significant effects on bone metabolism and turnover. Historically, treatment of stress fractures focused on conservative strategies such as rest and immobilisation. Calcium and vitamin D deficiencies have been closely linked to stress fractures and so over time supplementation has also played a role in treatment. With the introduction of biologics into orthopaedics, newer treatment strategies have been applied to accelerate fracture healing and perhaps improve fracture callus quality. If such therapies can reduce time spent away from sport and activity, it would be ideal for treating stress fractures. This article aims to offer insights into the evolving landscape of stress fracture management. It investigates the pre-clinical evidence and available published clinical applications. Though fracture healing is well understood, the role of biologics for fracture healing is still indeterminate. Available literature for the use of biologic therapies in stress fractures are restricted and most reports have used biologics as a supplement to surgical fixation in subjects in studies that lack control groups. Randomised control trials have been proposed and registered by a few groups, with results awaited. Assessing individuals for risk factors, addressing hormonal imbalances and nutritional deficiencies seems like an effective approach to addressing the burden of stress fractures. We await better designed trials and studies to accurately determine the clinical benefit of adding biologics to the management of these injuries.

Abstract
This comprehensive review explores the applications of platelet-rich plasma (PRP) in the context of compound fracture care, providing a thorough examination of its biological mechanisms, preparation techniques, and clinical implications. The analysis highlights PRP's potential in accelerating bone healing, enhancing soft tissue repair, reducing inflammation and infection risks, and managing pain during fracture recovery. The review underscores the importance of ethical and regulatory considerations in integrating PRP into orthopaedic practice, emphasising informed consent, transparent patient communication, and ongoing monitoring of ethical concerns. Looking ahead, the implications for the future of compound fracture care suggest a transformative shift with the potential for personalised medicine approaches and emerging technologies. However, the conclusion calls for a balanced perspective, acknowledging the promising applications of PRP while emphasising the need for responsible and ethical use. The collaborative efforts of healthcare professionals, researchers, and regulatory bodies are crucial in navigating this evolving landscape and harnessing the healing power of PRP to redefine orthopaedic care for individuals with compound fractures.

Abstract
Background: Jones fracture, or proximal fifth metatarsal fracture, is a common injury in National Football League (NFL)-caliber athletes. Combine draft performance can greatly impact the long-term success of these athletes, and substantial emphasis has been placed on early return to play (RTP) and the minimization of post-operative complications after Jones fracture in these athletes. To date, no study has specifically described the treatment and outcomes of this injury specifically in NFL-caliber players, considering factors relevant to this unique population. Thus, the purpose of this review is to delve into Jones fracture in NFL-caliber athletes, evaluating the diagnostic, treatment, and RTP considerations. Methods: We searched Medline (PubMed), Embase (Elsevier), Scopus (Elsevier), and SPORTDiscus (EBSCOhost) for the concept of Jones fractures in the NFL. Using the PRISMA guidelines, a team of three reviewers conducted abstract screenings, full-text screenings, and the extraction of studies describing Jones fractures specifically in the NFL. Results: Of the 1911 studies identified, 6 primary retrospective studies met the inclusion and exclusion criteria. The heterogeneity of the outcome reporting precluded a meta-analysis; thus, a qualitative review of manuscripts describing Jones fracture was carried out. Classification, diagnosis, and treatment considerations, RTP statistics and outcomes, and complications were discussed. Amongst the primary studies, there were 285 Jones fractures, all athletes were able to RTP, and the average time to RTP ranged from 6 weeks to 27 weeks. For complications, with operative treatment, the refracture rate ranged from 4 to 12%, and incomplete healing ranged from 7 to 50%. RTP was 15 weeks for refractures. There were no patient-reported outcomes. Conclusions: The vast majority of Zone 2/3 Jones fractures are treated with IM screw fixation with or without adjunctive orthobiologics, such as bone marrow aspirate concentrate, in NFL-caliber athletes. The six major series investigating outcomes after the operative treatment of Jones fractures in NFL players reveal very positive findings overall with regard to RTP, reoperation, and career continuation.

Abstract
Bone stress injuries (BSIs) are a frequent finding in athletes, particularly of the foot and ankle. A BSI is caused by recurring microtrauma to the cortical or trabecular bone exceeding the repair capacity of normal bone. The most frequent fractures at the ankle are low risk, characterized by a low risk for nonunion. These include the posteromedial tibia, the calcaneus, and the metatarsal diaphysis. High-risk stress fractures have a higher risk for nonunion and need more aggressive treatment. Examples are the medial malleolus, navicular bone, and the base of the second and fifth metatarsal bone.Imaging features depend on the primary involvement of cortical versus trabecular bone. Conventional radiographs may remain normal up to 2 to 3 weeks. For cortical bone, early signs of BSIs are a periosteal reaction or the "gray cortex sign," followed by cortical thickening and fracture line depiction. In trabecular bone, a sclerotic dense line may be seen. Magnetic resonance imaging enables early detection of BSIs and can differentiate between a stress reaction and a fracture. We review typical anamnestic/clinical findings, epidemiology and risk factors, imaging characteristics, and findings at typical locations of BSIs at the foot and ankle that may help guide treatment strategy and patient recovery.

Abstract
BACKGROUND Platelet-rich plasma (PRP) contains various growth factors and inflammatory regulators, which can effectively reduce inflammation in joints and promote tissue repair. Multiple studies have proved its effectiveness in the treatment of knee osteoarthritis (KOA). Low-intensity focused ultrasound (LIFU) and transcutaneous electrical nerve stimulation (TENS) are non-invasive and safe physical therapy methods for KOA. This study is the first to propose the treatment of KOA with physical stimulation after PRP treatment, and to observe the clinical efficacy of the treatment method. METHODS This is a protocol paper that outlines a randomized controlled trial, patients will be assigned randomly to the PRP group, PRP+LIFU group, PRP+TENS group, and PRP+LIFU combined TENS group. The patients will be followed at 12-week and 24-week time points to evaluate the primary and secondary outcomes of the study. The primary outcome is the VAS pain score. Secondary outcomes include Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) and International Knee Documentation Committee scores (IKDC). After baseline examination, all patients will sign a written informed consent for study participation after a full explanation of the treatment protocol. We have planned a total of 120 patients (30 patients per group). DISCUSSION The objective of this clinical trial is to evaluate the effect of different physical stimulation after PRP treatment for KOA. The data will be published after the completion of the study. TRIAL REGISTRATION This study has been registered with the Chinese Clinical Trials Registry. REGISTRATION NUMBER ChiCTR2200065119 (registered date: 10/28/2022).
