Background: The objective of this study was to compare the clinical outcomes of two internal fixation methods for high tibial osteotomy (HTO): double-triangle locking compression plate (DT-LCP) and T-shaped locking compression plate (T-LCP).

Methods: 202 adult patients in our hospital between January 2018 and December 2021 were included and followed up for at least one year: group 1(DT-LCP, 98 patients) and group 2 (T-LCP, 104 patients). Detailed information on demographics, preoperative and postoperative follow-up, surgical procedures, and complications were collected.

Purpose: This study aimed to demonstrate the application of orthotopic bone flap transplantation with a fibula transplantation (OBFT-FT) in open-wedge high tibial osteotomy (OW-HTO) and to assess the effect of OBFT-FT on gap healing.

Patients And Methods: From January to July 2020, 18 patients who underwent OW-HTO with OBFT-FT were reviewed for this study. Demographics, postoperative complications, and radiological and clinical outcomes of patients were collected.

Purpose: This study aimed to investigate the mid- to long-term benefits of high tibial osteotomy in advanced age patients.

Methods: This retrospective study was conducted in our hospital from January 2017 to January 2021 with data prospectively collected, 47 patients with knee osteoarthritis who over 65 years old were included, and a 1:1 propensity score (PS) of patients < 65 years were matched according to gender, body mass index, and side. Patient demographics, intraooperative and postoperative variables, and patient self-reported outcomes were compared.

Purpose: This study aimed to investigate postoperative patient satisfaction at mid- to long-term follow-up after proximal fibular osteotomy and to identify risk factors for patient dissatisfaction.

Methods: This was a retrospective cross-sectional study that included 252 knees from 160 osteoarthritis (OA) patients who underwent proximal fibular osteotomy with a follow-up of four to eight years. Patients were categorized into a satisfied group (satisfaction score ≥ 20) or a dissatisfied group (satisfaction score < 20) based on the New Knee Society Score (New KSS).

Objective: The Ward triangle is an important area used clinically to diagnose and assess osteoporosis and its fracture risk in the proximal femur. The main objective of this study was to investigate the rules of development and maturation of the trabeculae of Ward's triangle to provide a basis for the prevention and treatment proximal femur fracture.

Methods: From January 2018 to December 2019, individuals from 4 months to 19 years old who underwent hip growth and development assessments at the Third Hospital of Hebei Medical University were selected retrospectively.

Purpose: Proximal tibia osteotomy with absorbable spacer combined with fibular osteotomy (TPOASI) is an emerging surgical technique for treating knee osteoarthritis (KOA); however, the efficacy of this procedure remains unknown. We hypothesize that TPOASI can achieve similar clinical outcomes to opening-wedge high tibial osteotomy (OW-HTO). The objective of this study is to compare the clinical results between these two procedures.

Purpose: To investigate a prediction model of meniscus injury in patients with tibial plateau fracture.

Methods: This retrospective study enrolled patients with tibial plateau fractures who were treated in the Third Hospital of Hebei Medical University from January 1, 2015, to June 30, 2022. Patients were divided into a development cohort and a validation cohort based on the time-lapse validation method.

Objective: To explore changes in the epidemiological and clinical characteristics of patients who underwent knee arthroplasty (KA) over a 10-year period in China.

Methods: Medical records of patients with knee osteoarthritis (KOA), who underwent primary unilateral KA in 5 level I center hospitals in China between January 2011 and December 2020, were retrospectively reviewed and analyzed. To more clearly define changes over the years, patients were divided into two groups according to time of admission at 5-year intervals.

Objectives: This study aims to quantitatively evaluate the femoral-tibial contact pressure on the knee under certain malrotaional degrees.

Methods: Femoral-tibial contact pressure was carried out on 14 fixed rotational knee models under 200/400/600 N vertical load using ultra-low-pressure sensitive film technology, rotation angles including neutral position (0°, anatomically reduced), 5°, 10°, and 15° internally and externally. Data were collected and analyzed with SPSS software.

Background: This study aimed to identify the most frequent reasons for orthopedic medical malpractice, gain insight into the related patient demographics and clinical characteristics, and identify the independent factors associated with it.

Methods: We collected and analyzed the demographic and injury characteristics, hospital levels and treatments, medical errors, and orthopedist's degree of responsibility for the patients who were subject to orthopedic medical malpractice at our institution. Univariate and multivariate analyses were performed to identify the factors associated with the orthopedist's degree of responsibility in the medical malpractice cases.

Objective: Although many studies have reported risk factors of mortality following hip fracture surgery, the preventable risk factors of mortality following hip fracture surgery have not been well-identified. The aim of this study was to identify the preventable risk factors of mortality following hip fracture surgery.

Methods: We searched PubMed, Web of Science, Google scholar, and the Chinese National Knowledge Infrastructure (CNKI) databases from January 1997 to March 2017 for studies reporting risk factors of mortality following hip fracture surgery.

Purpose: Knee osteoarthritis (KOA) is the most common joint pathology worldwide and a major cause of later disability. It is unknown if the bone mass density (BMD) is correlated with KOA. This study aimed to investigate the prevalence of radiographic KOA among retired professional football players by comparing with matched nonsportsmen, and assess the correlation between BMD and KOA.

Objective: The purpose of this study was to verify the age-, gender- and Arbeitsgemeinschaft für Osteosynthesefragen (AO) type-specific clinical characters of adult tibial plateau fractures in 83 hospitals in China and to investigate whether altitude has potential relationships with adult tibial plateau fractures.

Methods: A retrospective investigation was performed on consecutive patients with tibial plateau fractures treated in 83 hospitals in China between January 2010 and December 2011, data including age, gender and imaging were collected retrospectively through the PACS system and case reports checking system, imaging were classified into six types under fully qualified estimation based on AO classification. To further investigate imparities among different altitudes in China, all data were classified into four groups according to the centre altitudes of each city, G1 = plains group (<500 m), G2 = hills group (500-1000 m), G3 = mountain areas group (1000-2000 m), and G4 = plateau group (>2000 m).

Background: Implant breakage after the fixation of traumatic fractures is rare; however, when it occurs, it is debilitating for the patients and a challenge for surgeons. The purpose of this study was to analyze and identify the independent risk factors for implant breakage of traumatic fractures treated with plate osteosynthesis.

Methods: We reviewed the medical records of patients with a fracture to any part of their four extremities, clavicle, hand or foot, who underwent surgical plate osteosynthesis from January 2005 to January 2015, and who sustained a subsequent implant breakage.
