The effect of intraoperative fluoroscopy on acetabular component positioning and patient anatomy restoration during total hip arthroplasty: A systematic review and meta-analysis.

Background: In total hip arthroplasty (THA), the positioning of components holds critical importance for factors such as joint stability, polyethylene liner wear, and range of motion. This meta-analysis aimed to compare the effects of intraoperative fluoroscopy (IF) versus no use of IF on component positioning and the restoration of patient anatomy during THA.

Methods: We conducted our systematic review following the recommendations outlined in the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guideline.

Chondrocyte membrane-coated nanoparticles promote drug retention and halt cartilage damage in rat and canine osteoarthritis.

Osteoarthritis (OA) is a chronic joint disease characterized by progressive degeneration of articular cartilage. A challenge in the development of disease-modifying drugs is effective delivery to chondrocytes. The unique structure of the joint promotes rapid clearance of drugs through synovial fluid, and the dense and avascular cartilage extracellular matrix (ECM) limits drug penetration.

Osteosarcoma and Its Advancement.

Cancer with its high mortality rate is really hard to treat even in this era. Extensive research work is still required to overcome the threat caused by the disease. Currently, the treatment modality is based on the combination therapy, and diagnostics is dependent upon biopsy results.

Identifying the Potential Role of Regional Bone Mineral Density on the Degree of Malleolar Involvement in Acute Ankle Fractures.

Ankle fractures are a common traumatic lower extremity injury and are generally classified and characterized by the rotational mechanism of injury. At each malleolus (i.e.

The Effect of Femoral Fixation on Revision and Mortality Following Elective Total Hip Arthroplasty in Patients Over the Age of 65 years. An Analysis of the American Joint Replacement Registry.

Background: With the overwhelming use of cementless femoral fixation for primary total hip arthroplasty in the United States, the associations of stem fixation on the risk of revision and mortality are poorly understood. We evaluated the relationship between femoral fixation and risk of revision and mortality in patients included in the American Joint Replacement Registry.

Methods: Elective, primary, unilateral total hip arthroplasties in the American Joint Replacement Registry, in patients over the age of 65 years were considered.

Platelet Rich Plasma in Orthopedic Surgical Medicine.

There is a global interest in optimizing post-surgical tissue repair strategies, leading to better patient outcomes and fewer complications, most ideally with reduced overall cost. In this regard, in recent years, the interest in autologous biological treatments in orthopedic surgery and sports medicine has increased greatly, and the addition of platelet-rich plasma (PRP) to the surgical armamentarium is of particular note. Unfortunately, the number of PRP preparation devices has also grown immensely over the recent decades, raising meaningful concern for the considerable variation in the qualities of currently available PRP preparations.

Outcomes after Surgical Repair of Medial Meniscal Root Tears: A Review.

At the present time, there is a paucity of literature regarding medial meniscal posterior root repair and outcomes. This review seeks to examine the currently available data to further elucidate the clinical risks and benefits and any associated risks of medial meniscal posterior root repair. A systematic literature search was performed up to July 2018 in the databases of Medline via PubMed, EBSCOhost, and EMBASE.

The Biomechanical Performance of the Latest All-Inside Meniscal Repair Devices.

Purpose: To evaluate the biomechanical characteristics of recently introduced meniscal repair devices with a hand-tied, inside-out meniscal suture in a human meniscus model.

Methods: In detached adult human menisci, vertical longitudinal cuts were created 3 mm from the synovial-meniscal junction, simulating a bucket-handle meniscal tear. Each cut was repaired using a single device.

A Biomechanical Comparison of Six Suture Configurations for Soft Tissue-Based Graft Traction and Fixation.

Purpose: The purpose of this study was to compare 6 different graft fixation techniques to determine the preparation speed, fixation security, biomechanical strength, and resultant tissue trauma.

Methods: Six different techniques (10 samples each): #2 OrthoCord Krackow stitch, #2 FiberWire Krackow stitch, SpeedTrap, WhipKnot, Loop-in-loop stitch were created in the distal 3 cm of 9 cm bovine flexor tendons. The proximal 3 cm tendon segment was clamped in a testing machine and the distal suture ends secured by pneumatic grips.

The Surgical Applications of Biologics in Sports Medicine.

Over the past 25 years an increased appreciation of the positive impact of biologic interventions has driven significant advances in the surgical treatment of shoulder and knee conditions. These biologic adjuncts to treatment promote improved outcomes and have set the stage and increased research and development in this arena.

THE LOWER EXTREMITY GRADING SYSTEM (LEGS) TO EVALUATE BASELINE LOWER EXTREMITY PERFORMANCE IN HIGH SCHOOL ATHLETES.

Background And Purpose: Lower extremity athletic injuries result in impairments in balance, power, and jump-landing mechanics. Unilateral injury has bilateral effects and the literature supports that it is important to assess neuromuscular impairments such as balance, power, and jumping mechanics following injury and for safe return to sport after injury rehabilitation. Currently, individual tests are established in the literature, but no combined approach or clinical tool exists for this purpose.

An Autologous Anti-Inflammatory Protein Solution Yielded a Favorable Safety Profile and Significant Pain Relief in an Open-Label Pilot Study of Patients with Osteoarthritis.

Osteoarthritis (OA) is a progressive and degenerative disease, which may result in significant pain and decreased quality of life. Recent updates in our understanding of OA have demonstrated that it is a whole joint disease that has many similarities to an unhealed wound containing inflammatory cytokines. The nSTRIDE Autologous Protein Solution (APS) Kit is a medical device under development for the treatment of OA.

Two-Year Outcomes from a Randomized Controlled Trial of Minimally Invasive Sacroiliac Joint Fusion vs. Non-Surgical Management for Sacroiliac Joint Dysfunction.

Background: Sacroiliac joint (SIJ) dysfunction is an important and underappreciated cause of chronic low back pain.

Objective: To prospectively and concurrently compare outcomes after surgical and non-surgical treatment for chronic SIJ dysfunction.

Methods: One hundred and forty-eight subjects with SIJ dysfunction were randomly assigned to minimally invasive SIJ fusion with triangular titanium implants (SIJF, n = 102) or non-surgical management (NSM, n = 46).

Biomechanical Performance of Hip Labral Repair Techniques.

Purpose: To determine the strength of various suture techniques and the impact of suture passer size on cyclically loaded hip labra.

Methods: We assigned 63 bovine hip labra to 9 simple knotless suture technique groups using OrthoCord suture: (1) penetrating grasper (2.6 mm)-placed horizontal mattress, (2) penetrating grasper-placed vertical mattress, (3) SutureLasso (1.

Sacroiliac Joint Fusion Using Triangular Titanium Implants vs. Non-Surgical Management: Six-Month Outcomes from a Prospective Randomized Controlled Trial.

Background: Sacroiliac (SI) joint pain is a prevalent, underdiagnosed cause of lower back pain. SI joint fusion can relieve pain and improve quality of life in patients who have failed nonoperative care. To date, no study has concurrently compared surgical and non-surgical treatments for chronic SI joint dysfunction.

Improving residency training in arthroscopic knee surgery with use of a virtual-reality simulator. A randomized blinded study.

Background: There is a paucity of articles in the surgical literature demonstrating transfer validity (transfer of training). The purpose of this study was to assess whether skills learned on the ArthroSim virtual-reality arthroscopic knee simulator transferred to greater skill levels in the operating room.

Methods: Postgraduate year-3 orthopaedic residents were randomized into simulator-trained and control groups at seven academic institutions.
