A Retrospective Cohort Study of the Effects of Canal Filling Ratio and Femoral Bone Density Change on the Outcomes of Anatomical and Double-tapered Wedge Stems.

 This study aims to compare the proximal femoral bone density changes in follow-up X-ray imaging and the proximal filling ratios of stems between anatomical and double-tapered wedge stem designs.  Patients aged between 18 and 80 years who received primary total hip arthroplasty using both types of stems between 2017 and 2019 and had follow-up tests for up to a year were included in the study. Canal filling ratios at 3 levels (lesser trochanter [LT], 2 cm above LT, and 7 cm below LT) using the optimal densitometry method.

LONG-TERM OUTCOMES OF USING VARIOUS GRAIN ALLOGRAFT SIZES IN PAPROSKY TYPE 3.

Introduction: Severe acetabular bone defects can pose challenges in revision total hip replacement. The use of structural allografts and various sizes of grain allografts has been proposed as an alternative surgical technique for treating Paprosky type 3 acetabular defects. This study aimed to evaluate the long-term outcomes and potential complications associated with this approach.

Efficacy of a Combined Periarticular and Intraosseous Multimodal Analgesic Injection Technique in Simultaneous Bilateral Total Knee Arthroplasty: A Randomized Controlled Trial.

Introduction Early postoperative pain poses a challenge for surgeons to manage after total knee arthroplasty (TKA). Various techniques have been employed to optimize pain reduction, including Periarticular Multimodal Analgesia (PMA), recognized as a safe and effective method. Our study aims to enhance PMA through a combined intraosseous injection (PMA-I) and compare it with standard PMA.
