Three-dimensional analysis of bone site grafting on the upper extremity on computed tomography scans.

Purpose: To perform a quantitative analysis of the amount of cancellous bone in the distal radius and olecranon process by segmentation of computed tomographic scans. As a secondary analysis, the bone density by Hounsfield units was evaluated at the same sites.

Methods: Computed tomography angiography images of the upper extremity were analyzed using 3-D Slicer™ medical imaging software.

Quantitative Volumetric Measurements of Bone Grafting Sites Within the Lower Extremity on Computed Tomography Scans.

The anterior iliac crest is one of the most used options; however, pain and other complications have been reported. Other options for bone harvest in the lower extremity, such as the proximal tibia and calcaneus, can be useful sites for bone grafting. Computed tomography angiography images of the lower extremity were analyzed using 3-D Slicer™ medical imaging software, creating an advanced 3-dimensional model.

The Effects of the Combination of Rhein and Platelet-Rich Plasma on Human Articular Chondrocytes.

Background: The presence of side effects and low bioavailability of rhein has limited its use in the treatment of osteoarthritis. We aimed to evaluate the in vitro response of human articular chondrocytes to the presence of the combination of platelet-rich plasma (PRP) and rhein.

Methods: Solutions of rhein were prepared to assess solubility and select a working concentration.

Comparison of Anterior Iliac Crest Versus Proximal Tibia Autologous Bone Graft Harvesting: A Systematic Review and Meta-Analysis.

Anterior iliac crest (AIC) is the preferred option for bone grafting; however, pain and complications are reported. Proximal tibia (PT) is a sourceful site for bone grafting with lower complications. MEDLINE, EMBASE, and Scopus were searched to identify studies comparing AIC and PT autograft procedure.

Open Inferior glenohumeral joint dislocation with complete range of motion recovery: Case Report and literature review.

Luxatio erecta is an inferior glenohumeral dislocation. It is an uncommon pathology with a prevalence of 0.5% of all shoulder dislocations.

The use of platelet-rich plasma in studies with early knee osteoarthritis versus advanced stages of the disease: a systematic review and meta-analysis of 31 randomized clinical trials.

Introduction: Reports have concluded that platelet-rich plasma (PRP) is an effective and safe biological approach to treating knee osteoarthritis (OA). However, the effectiveness of PRP in advanced stages of the disease is not entirely clear. The purpose of this study was to evaluate whether the use of PRP would be as effective in studies with early-moderate knee OA patients compared to studies including patients with end-stage OA, based on the Kellgren-Lawrence classification.

Spinal epidural hematoma in antiphospholipid syndrome: case report and review of the literature.

Introduction: Spinal epidural hematomas are a surgical emergency, the delay in diagnosis can develop devastating sequelae due to its acute and progressive course. If not treated properly, it may lead to death or permanent neurological deficit. It is a rare condition that can occur in patients with hematologic pathology.

Double-Row Rotator Cuff Repair Enhanced With Platelet-Rich Therapy Reduces Retear Rate: A Systematic Review and Meta-analysis of Randomized Controlled Trials.

Purpose: To assess retear rates in arthroscopic double-row rotator cuff repair (double-row RCR) with and without platelet-rich therapy (PRT).

Methods: Systematic review and meta-analysis of randomized controlled trials (RCTs). MEDLINE, Embase, and Scopus databases were searched for RCTs involving use of PRT exclusively in arthroscopic double-row RCR.

Anti‑inflammatory and anti‑catabolic effect of non‑animal stabilized hyaluronic acid and mesenchymal stem cell‑conditioned medium in an osteoarthritis coculture model.

Previous clinical studies have reported the clinical effectiveness of non‑animal stabilized hyaluronic acid (NASHA) and adipose‑derived mesenchymal stromal/stem cells (MSC) in the treatment of knee osteoarthritis (OA). Unlike MSC secreted mediators, in vitro anti‑inflammatory effects of NASHA have not been evaluated. We aimed to evaluate and compare the anti‑inflammatory effect of NASHA and MSC conditioned medium (stem cell‑conditioned medium; SC‑CM), in an explant‑based coculture model of OA.

Effect of Normal Saline Injections on Lateral Epicondylitis Symptoms: A Systematic Review and Meta-analysis of Randomized Clinical Trials.

Background: Lateral epicondylitis, or tennis elbow, is a painful degenerative disorder that commonly occurs in adults between 40 and 60 years of age. Normal saline (NS) injections have been used as placebo through a large number of randomized controlled trials (RCTs) focused on the treatment of lateral epicondylitis.

Purpose: This meta-analysis of RCTs aimed to assess the therapeutic effect of NS injections on lateral epicondylitis symptoms and compare results with established minimal clinically important difference criteria.

Comparison of the Clinical Effectiveness of Single Versus Multiple Injections of Platelet-Rich Plasma in the Treatment of Knee Osteoarthritis: A Systematic Review and Meta-analysis.

Background: Reports have concluded that platelet-rich plasma (PRP) is an effective and safe biological approach in the treatment of knee osteoarthritis (OA). However, no consensus has been established regarding the number of injections required to observe a therapeutic effect.

Purpose: To compare the clinical effectiveness reported in randomized controlled trials (RCTs) of single versus multiple PRP injections in the treatment of knee OA.

Intraarticular injection of platelet-rich plasma in knee osteoarthritis: single versus triple application approach. Pilot study.

Objective: To compare the clinical effectiveness of the triple intra-articular injection of platelet-rich plasma (PRP) with respect to the single injection in patients with mild osteoarthritis of the knee.

Methods: A total of 35 patients with a clinical and radiographic diagnosis of osteoarthritis grade I and II were analyzed. They were randomized into two groups: single application (18 patients) and triple application (17 patients).

Effect of collagen supplementation on osteoarthritis symptoms: a meta-analysis of randomized placebo-controlled trials.

Purpose: Osteoarthritis (OA) is one of the most common causes of disability and a prevalent chronic disease. The use of collagen is growing due to the satisfactory results in the treatment of OA. However, the possible beneficial effects of collagen for the treatment of OA are currently controversial.
