Biomechanical Analysis and Solution Suggestions of Screw Replacement Scenarios in Femoral Neck Fracture Surgeries: Finite Element Method.

Objective: Despite several surgical options, there has yet to be a consensus on the best treatment for femoral neck fracture (FNF) due to higher complication rates compared to other bone fractures. This study aims to examine the possible consequences and solution suggestions of changing screws during surgery for various reasons in FNF surgical treatment from a biomechanical perspective.

Method: FNF and treatment materials were analyzed biomechanically using a package program based on the finite element method (FEM).

Effects of obesity on clinical outcomes in diminished ovarian reserve patients undergoing intracytoplasmic sperm injection cycles.

The aim of this study is to evaluate the effects of obesity on clinical outcomes in diminished ovarian reserve (DOR) patients undergoing intracytoplasmic sperm injection cycles. In this retrospective observational cross-sectional study, women admitted to current clinic with DOR undergoing intracytoplasmic sperm injection were divided into 2 groups according to the obesity. Patient age, body mass index, anti-mullerian hormone, baseline follicle stimulating hormone and baseline estradiol levels, antral follicle count, total gonadotropin dose, day of stimulation, number of mature (MII) oocytes, and clinical pregnancy were evaluated.

Comparison of bilateral cementless total knee arthroplasty results between patients in different BMI groups.

Introduction: The aim of this study was to compare the results of cementless bilateral total knee arthroplasty (TKA) between individuals in different obesity groups.

Materials And Methods: This was a retrospective cohort study. Patients with a body mass index (BMI) greater than 25 who underwent bilateral TKA for gonarthrosis between 2014 and 2020 and completed a minimum follow-up of 24 months were included.

Effects of preoperative anxiety level on pain level and joint functions after total knee arthroplasty.

This study examined the effect of preoperative anxiety level on postoperative pain, opioid and nonopioid analgesic use requirements and joint function in patients undergoing primary knee arthroplasty for knee osteoarthritis. 106 patients were included in the study. Situational anxiety score (STAI-S) and trait anxiety score (STAI-T) were divided into two groups as below and above 40.
