Does the Combination of Platelet-rich Plasma and Supervised Exercise Yield Better Pain Relief and Enhanced Function in Knee Osteoarthritis? A Randomized Controlled Trial.

Background: Knee osteoarthritis is a leading cause of disability with substantial healthcare costs, and efficient nonsurgical treatment methods are still needed. Platelet-rich plasma (PRP) injections and exercise therapy are used frequently in clinical practice. Whether PRP or PRP combined with exercise is more effective than exercise alone is unclear.

Comparison of Staple, Anchor, and Tenodesis Screw for Posterior Tibialis Tendon Fixation: A Biomechanical Analysis.

Various posterior tibialis tendon fixation techniques are described in literature. Suture anchor, staple and tenodesis screws are widely used for posterior tibialis tendon transfer, but their stiffness and the maximal ultimate failure load were not tested before. We aimed to compare the initial ultimate failure load and stiffnesses of suture anchor, staple and tenodesis screws on bovine tendon fixation to bovine metaphyseal bone.

Methods: A total of 62 patients (mean age: 56.68 ± 7.

FIXATION METHODS IN LATARJET: BIOMECHANICAL COMPARISON OF SCREW TYPES AND PLATE FIXATION.

Objective: Latarjet procedure is often preferred in recurrent shoulder dislocations accompanied by glenoid bone loss. It is observed that the superiority of bone graft fixation methods is still controversial. The aim of this study is to biomechanically compare the bone graft fixation methods in the Latarjet procedure.

Ionized and non-ionized radiation effects on coronary stent implantation.

The purpose of this study is to examine the clinical radiation effects on patients with various stents. Several previous researches focused on the mechanical and physical features of the stents, but there have been few studies that focus on the interaction with radiological and clinical radiation. For stent material analysis, the ANSYS package program was employed.

Evaluation of F-18 FDG radiopharmaceuticals through Molecular Docking and radiation effects.

Fluorodeoxyglucose (FDG), marked with the most used Positron Emission Tomography (PET) radiopharmaceutical Fluorine-18 (F-18), is a glucose analog and is taken to living cells through membrane glucose carriers. F-18 FDG involvement in tissue is proportional to glucose use. In many cancers, there is increased glucose use due to increased gluten expression and hexokinase activity.

Anatomical bone structure differences in patients with hemophilic arthropathy of the knee.

Objectives: The anatomical differences of the bony structure of the knee joint in patients with hemophilia were evaluated, and the results were compared with the knees of patients with primary gonarthrosis and no arthrosis.

Material And Methods: This study reviewed 41 knees in 21 patients (with an Arnold-Hilgartner classification of Stages 4 and 5 hemophilic arthropathy) who underwent total knee arthroplasty in single center. Two control groups including 21 asymptomatic patients (42 knees) and 21 primary knee osteoarthritis patients (42 knees) were formed to compare the measurements with hemophiliacs.

Comparison of Monte Carlo simulations and theoretical calculations of nuclear shielding characteristics of various borate glasses including Bi, V, Fe, and Cd.

The aim of this study is to evaluate both buildup factors and photon attenuation effectiveness of some borate glasses doped by Cd, Fe, V, and Bi. The mass attenuation coefficients (μ) of these glass systems have been calculated via MCNP6 and GEANT4 computer simulation codes over 0.02-10 MeV energy range and compared with the theoretical results of WinXCOM program.

Pre-clinic study of radiopharmaceutical for Covid-19 inactivation: Dose distribution with Monte Carlo Simulation.

Monte Carlo simulation method and Nuclear Medicine MIRD method were used to evaluate the effect of radiopharmaceuticals on Covid-19 disease. The mean absorbed organ dose in the target organ and gamma radiation emitter attenuation properties such as linear attenuation coefficients, energy absorption build-up factors (EABF), exposure build-up factors (EBF), and relative dose distributions (RDD) were examined. The results showed that radiopharmaceuticals containing gamma radiation emitters which are densely ionizing charged particles induced membrane damage and produced protein damage.

Reasons for resident resignations from Orthopedic Residency Programs in Turkey: A cross-sectional survey from residents' perspectives.

Objective: The aim of this study was to analyse the factors that led to resignations from Orthopaedics and Traumatology Residency pro- grammes in Turkey, and to determine the overall rate of resignation among residents from Orthopaedics and Traumatology programmes.

Methods: In this cross-sectional survey,120 residents who either resigned or transferred to other OT clinics between autumn of 2013 and spring of 2020 were included. They were asked to complete a questionnare which was sent via Whatssapp application or e-mail.

The Effects of Different Screw Combinations on the Initial Stability of Ankle Arthrodesis.

Background: The literature is scanty regarding the biomechanical effects of different thread configurations on the initial stability of ankle arthrodesis. This study aims to compare the initial stability of tibiotalar fusion site in ankle arthrodesis using cannulated screws with different thread designs.

Methods: We biomechanically tested under cyclic loading the effects of different screw combinations on the initial stability of ankle arthrodesis.

Symptomatic osteonecrosis of the hip and knee in patients with systemic lupus erythematosus: Prevalence, pattern, and comparison of natural course.

Objective: Osteonecrosis (ON), also known as avascular necrosis, is characterized by the collapse of the architectural bone structure secondary to the death of the bone marrow and trabecular bone. Osteonecrosis may accompany many conditions, especially rheumatic diseases. Among rheumatic diseases, osteonecrosis is most commonly associated with systemic lupus erythematosus (SLE).

Internal fixation for osteochondritis dissecans lesions of the knee in patients with physeal closure.

Objective: The aim of this study was to present mid-term functional and radiological outcomes of patients with physeal closure who underwent arthroscopic or open internal fixation with headless cannulated compressive screws due to unstable Osteochondritis Dissecans (OCD) lesions of the knee.

Methods: With a diagnosis of unstable OCD of the knee, ten consecutive patients (seven male, three female) with physeal closure (mean age: 23 years; range: 17-40), underwent arthroscopic or open internal fixation with headless cannulated compressive screws. The patients were retrospectively reviewed based on functional and radiological data, with a mean follow-up of 42 months (range: 27-61).

The Combination of Exercise and Manual Therapy Versus Exercise Alone in Total Knee Arthroplasty Rehabilitation: A Randomized Controlled Clinical Trial.

Background: Total knee arthroplasty (TKA) is one of the most commonly performed orthopedic surgeries in the lower extremity. However, patient dissatisfaction and functional disability are mostly experienced because of pain and limited range of motion (ROM). Although manual therapy is commonly implemented to improve ROM and modulate pain in the management of musculoskeletal disorders, there is a lack of evidence about its clinical effectiveness on postoperative TKA rehabilitation.

Bizarre Parosteal Osteochondromatous Proliferation (Nora's Lesion) in the Medial Sesamoid of the First Toe.

Bizarre parosteal osteochondromatous proliferation, or Nora's lesion, is a unique bony lesion that generally originates from the small bones of the hands and feet in young adults. We report a case of a bizarre parosteal osteochondromatous proliferation originating from the medial sesamoid of the first toe that was managed surgically by en bloc excision. At 5-year follow-up, there was no evidence of recurrence.
