The comparative and prospective study on efficacy and functional outcome of autologous platelet rich plasma injection vs hydrodissection in adhesive capsulitis of shoulder

Background: Adhesive capsulitis of should is also called frozen shoulder which describes a chronic, indolent pathological process in which the body forms excessive adhesions across the glenohumeral joint which in turn leads to pain, stiffness, and loss of range of movements which compromises the quality of life. The objective of the study was to evaluate the efficacy and functional outcome of autologous PRP injection and hydrodissection in adhesive capsulitis of shoulder.Methods: After excluding the patients who failed to satisfy the study protocol, the remaining 100 patients are divided equally into two groups namely group A (n=50) who receive autologous PRP injection and group B (n=50) who receive hydrodissection for adhesive capsulitis of shoulder. Both group participants are followed up pre-procedurally and post-procedurally at the end of 1st, 6th and 12th month for pain relief and range of movements. The improvements in pain and range of movements are charted in terms of VAS and DASH scoring system.Results: The statistical analysis were done for 46 patients in group A and 45 patients in group B which showed a statistical improvement in pain and range of movements (p<0.001 for VAS score and p<0.01 for DASH score) in group A who received autologous platelet rich plasma therapy. Autologous PRP therapy improves the functional quality of life with a long term outcome.Conclusions: For adhesive capsulitis of shoulder, autologous PRP therapy remains functionally superior than hydrodissection as autologous PRP is a constructive procedure by rejuvenating the degenerative tissues.

Management of intercondylar fractures of the distal humerus in adults using bi-columnar plating through trans-olecranon approach

Background: Inter-condylar fractures of the distal humerus are uncommon injuries and present the most difficult challenge among fractures of the lower end of the humerus. The principle involves anatomical reduction and fixation with stabilization of extra-osseous implants. The functional outcome has been greatly influenced by the early graduated rehabilitative exercise. We aimed to evaluate the functional outcome of inter-condylar fractures of the distal humerus in adults using bi-columnar plating through a trans-olecranon approach.Methods: A prospective study with 40 adult patients with inter-condylar fracture of the distal humerus were managed with bi-columnar plating through a trans-olecranon approach and were followed up for 12 months. The functional outcome was analysed by Mayo’s Elbow Performance Score (MEPS) at the end of 12 months follow up.Results: The average age of study participants were 50.8 years. A total of 24 cases were due to RTA and 16 cases were due to direct falls. Out of 40 cases, 6 (15%) were of B1 type, 2 (5%) were of type B2, 12 (30%) were of C1, 10 (25%) of C2, and 10 (25%) were of the type of C3 according to AO classification. According to MEPS at the end of the 12th-month follow-up, excellent results were seen in 24 (60%), good in 8 (20%), fair in 6 (15%), and poor results in 2 (5%) cases.Conclusions: Anatomically, bi-columnar plating for distal humerus is useful in providing stable fixation for complex distal articular fractured by trans-olecranon approach and facilitating early postoperative rehabilitation. Clinical and radiological results showed a good healing rate with a good range of motion.

The emerging role of exosomes in innate immunity, diagnosis and therapy

Exosomes, which are nano-sized transport bio-vehicles, play a pivotal role in maintaining homeostasis by exchanging genetic or metabolic information between different cells. Exosomes can also play a vital role in transferring virulent factors between the host and parasite, thereby regulating host gene expression and the immune interphase. The association of inflammation with disease development and the potential of exosomes to enhance or mitigate inflammatory pathways support the notion that exosomes have the potential to alter the course of a disease. Clinical trials exploring the role of exosomes in cancer, osteoporosis, and renal, neurological, and pulmonary disorders are currently underway. Notably, the information available on the signatory efficacy of exosomes in immune-related disorders remains elusive and sporadic. In this review, we discuss immune cell-derived exosomes and their application in immunotherapy, including those against autoimmune connective tissue diseases. Further, we have elucidated our views on the major issues in immune-related pathophysiological processes. Therefore, the information presented in this review highlights the role of exosomes as promising strategies and clinical tools for immune regulation

Impact of the Process Variables on the Yield of Mesenchymal Stromal Cells from Bone Marrow Aspirate Concentrate

Human bone marrow (BM) has been highlighted as a promising source of mesenchymal stromal cells (MSCs) containing various growth factors and cytokines that can be potentially utilized in regenerative procedures involving cartilage and bone. However, the proportion of MSCs in the nucleated cell population of BM is only around 0.001% to 0.01% thereby making the harvesting and processing technique crucial for obtaining optimal results upon its use in various regenerative processes. Although several studies in the literature have given encouraging results on the utility of BM aspiration concentrate (BMAC) in various regenerative procedures, there is a lack of consensus concerning the harvesting variables such as choice of anesthetic agent to be used, site of harvest, size of the syringe to be used, anticoagulant of choice, and processing variables such as centrifugation time, and speed. In this review article, we aim to discuss the variables in the harvesting and processing technique of BMAC and their impact on the yield of MSCs in the final concentrate obtained from them

Osteogenic and Chondrogenic Potential of Periosteum-Derived Mesenchymal Stromal Cells: Do They Hold the Key to the Future?

The periosteum, with its outer fibrous and inner cambium layer, lies in a dynamic environment with a niche of pluripotent stem cells for their reparative needs. The inner cambium layer is rich in mesenchymal progenitors, osteogenic progenitors, osteoblasts, and fibroblasts in a scant collagen matrix environment. Their role in union and remodeling of fracture is well known. However, the periosteum as a source of mesenchymal stem cells has not been explored in detail. Moreover, with the continuous expansion of techniques, newer insights have been acquired into the roles and regulation of these periosteal cells. From a therapeutic standpoint, the periosteum as a source of tissue engineering has gained much attraction. Apart from its role in bone repair, analysis of the bone-forming potential of periosteum-derived stem cells is lacking. Hence, this article elucidates the role of the periosteum as a potential source of mesenchymal stem cells along with their capacity for osteogenic and chondrogenic differentiation for therapeutic application in the future

Evidence-based informed consent form for total knee arthroplasty

Abstract Introduction Informed consent documentation is often the first area of interest for lawyers and insurers when a medico-legal malpractice suit is concerned. However, there is a lack of uniformity and standard procedure about obtaining informed consent for total knee arthroplasty (TKA). We developed a solution for this need for a pre-designed, evidence-based informed consent form for patients undergoing TKA. Materials and methods We extensively reviewed the literature on the medico-legal aspects of TKA, medico-legal aspects of informed consent, and medico-legal aspects of informed consent in TKA. We then conducted semi-structured interviews with orthopaedic surgeons and patients who had undergone TKA in the previous year. Based on all of the above, we developed an evidence-based informed consent form. The form was then reviewed by a legal expert, and the final version was used for 1 year in actual TKA patients operated at our institution. Results Legally sound, evidence-based Informed Consent Form for Total Knee Arthroplasty. Conclusion The use of legally sound, evidence-based informed consent for total knee arthroplasty would be beneficial to orthopaedic surgeons and patients alike. It would uphold the rights of the patient, promote open discussion and transparency. In the event of a lawsuit, it would be a vital document in the defence of the surgeon and withstand the scrutiny of lawyers and the judiciary

Dose–Response Meta-Analysis of Corticosteroid Effects in SARS Outbreak: A Model for Risk Stratification and Screening Strategy for Osteonecrosis of Femoral Head Post-Corticosteroid Therapy for COVID-19

Corticosteroids (CS) have been used in the management regimens for COVID-19 disease to mitigate the cytokine storm and ill effects of the pulmonary inflammatory cascade. With the rampant use of CS, clinicians started reporting the occurrence of osteonecrosis of the femoral head (OFH). In this systematic review, we aim to analyze the literature and identify the definitive cumulative dose and duration of CS needed for the development of OFH based on the SARS model and generate a risk-based screening recommendation for OFH in convalescent COVID-19 patients to facilitate early identification and management. An electronic database search was conducted until December 2022 in PubMed, Web of Science, Embase, and CNKI (China Knowledge Resource Integrated Database). Studies involving CS therapy and osteonecrosis data in SARS patients were included. Three authors independently extracted the data from the included studies and a dose–response meta-analysis was performed for various doses and duration of CS utilized in the included studies. We selected 12 articles with 1728 patients in the analysis. The mean age was 33.41 (±4.93) years. The mean dosage of CS administered was 4.64 (±4.7) g which was administered for a mean duration of 29.91 (±12.3) days. The risk of osteonecrosis increases at pooled OR of 1.16 (95% CI 1.09–1.23, p p < 0.001) per 5 days of increase in the cumulative duration of CS usage. A cumulative dosage of 4 g and a duration of 15 days were determined as the critical cut-off for the non-linear dose–response relationship observed. Appropriate and frequent screening of these individuals at regular intervals would help in the identification of the disease at an early stage in order to treat them appropriately
