Thicker polyethylene inserts for varus deformity versus thinner inserts for flexion contracture in total knee arthroplasty: a retrospective comparative study

Seung‐Hun Lee, Hyuck Min Kwon, Woo-Suk Lee, Kwan Kyu Park

BACKGROUND: The success of total knee arthroplasty (TKA) depends on achieving precise mechanical alignment and stable soft tissue balance, with the thickness of the final polyethylene (PE) insert serving as a critical component. However, the impact of preoperative factors on PE thickness …

Comparison of mechanical and clinical outcomes between cement-augmented and conventional cephalomedullary nailing in osteoporotic trochanteric fractures: a propensity score-matched cohort study

Jun Young Park, Tae Kang Kim, Byung Woo Cho, Hyuck Min Kwon et autres

BACKGROUND: Trochanteric fractures in the older population are challenging to treat due to osteoporotic bone and high risk of fixation failure. Cement augmentation (CA) of cephalomedullary fixation has been proposed to enhance implant anchorage and reduce complications. This study compared mechanical failure …

Enhanced Magnetic Resonance Imaging–Based Knee Cartilage Segmentation Using a Swin-UNet Conditional Generative Adversarial Network: Development and Validation Study (Preprint)

Jun Young Park, Jae Yeal Nam, Shakhboz Abdigapporov, Jong-Keun Kim et autres

BACKGROUND Accurate segmentation of cartilage from magnetic resonance imaging (MRI) is crucial for the diagnosis and surgical planning of knee osteoarthritis. However, manual segmentation is time-consuming, and conventional computed tomography–based surgical systems are limited by their inability to visualize cartilage. OBJECTIVE This …

Predictors of flexion contracture progression following total knee arthroplasty: role of global sagittal alignment and patient age

Woo-Suk Lee, Byung Woo Cho, Hyuck Min Kwon, Tae Hyung Kim et autres

BACKGROUND: Knee flexion contracture (KFC) progression after total knee arthroplasty (TKA) can significantly affect functional outcomes through disruption of the biomechanical knee-hip-spine kinetic chain. This study was conducted to investigate whether preoperative global sagittal alignment parameters, particularly the center of the acoustic …

Effect of Peripheral Nerve Block on Post-operative Pain and opioid use compared to Periarticular Multimodal Drug Injection following Total Hip Arthroplasty - A Protocol for Systematic Review and Meta-analysis v1

Soutrik Kundu, Kwan Kyu Park, Hyuck Min Kwon, Tae Hyung Kim et autres

INTRODUCTION This protocol for a systematic review and meta-analysis aims to provide evidence to assess whether Peripheral Nerve Block (PNB) is more effective than Peripheral Multimodal Drug Injection (PMDI) in managing postoperative pain and decreasing analgesic consumption after total hip arthroplasty. METHOD …

Short-term anabolic agent and sequential therapy to improve bone mineral density and bone turnover markers in patients with osteoporotic hip fractures

Jun Young Park, Jun-Young Lim, Tae Kang Kim, Byung Woo Cho et autres

BACKGROUND: Therapy using anabolic and antiresorptive agents in sequence is reportedly effective for severe osteoporosis management. However, evidence for this approach in osteoporotic hip fracture patients remains limited. This study aimed to evaluate the effectiveness of sequential therapy using short-term anabolic agents …

Comparative Analysis of 3 Machine Learning Methods for Identifying Minimal Predictors of Patellofemoral Instability Risk Factors

Hyuck Min Kwon, Ji‐Hoon Nam, Yong‐Gon Koh, Yoowang Choi et autres

Background: Magnetic resonance imaging (MRI) assessments are considered important for predicting patellar dislocation. Risk factors for patellar dislocation have not yet been clearly identified. Purpose: To identify patellofemoral instability anatomic risk factors using MRI and enhance the area under the curve (AUC) …

Clinical safety and efficacy of simultaneous bilateral total knee arthroplasty in an Asian population: a propensity score-matched analysis

Kwan Kyu Park, Hyuck Min Kwon, Byung Woo Cho, Tae Sung Lee et autres

BACKGROUND: Clear clinical guidelines on performing simultaneous bilateral total knee arthroplasty (BTKA) are lacking. We compare the clinical outcomes between BTKA and unilateral total knee arthroplasty (UTKA) using propensity score matching to assess safety and clinical efficacy, hypothesizing no difference in clinical …
