Direct anterior approach for total hip arthroplasty with patients in the lateral decubitus versus supine positions: A prospective, double-blinded, randomized clinical trial.

Purpose: The direct anterior approach (DAA) for total hip arthroplasty (THA) can be performed with patients in either in the lateral decubitus or supine position. Prompted by the lack of studies addressing differences between the two positions, this investigation aimed to examine clinical and radiographic outcomes and compare the lateral decubitus versus the supine position for THA using the DAA.

Methods: Between January 1 and October 1, 2020, 90 patients who underwent primary unilateral THA using the DAA were recruited, with 54 (60%) undergoing THA in the supine position (SP group) and 36 (40%) in the lateral decubitus position (LP group).

Influence of sagittal degenerative spondylolisthesis on anteversion of the acetabular component in total hip arthroplasty.

Background: Degenerative lumbar spondylolisthesis (DSPL), as opposed to other degenerative spinal conditions, is disregarded in the assessment of hip stability after total hip arthroplasty (THA). This study aimed to determine whether patients with DSPL have different acetabular anteversion compared to patients with normal spine before and following THA.

Methods: Preoperative and postoperative 6‑month lateral pelvic radiographs in standing and sitting positions from 91 patients who underwent primary THA were retrospectively compared for spinopelvic parameters between patients with DSPL (n = 31) and with normal spine (n = 34).

Level of physical activity among middle-aged and older Chinese people: evidence from the China health and retirement longitudinal study.

Background: With data from different regions accumulated, physical inactivity (PI) was found to be pandemic worldwide. Using China Health and Retirement Longitudinal Study (CHARLS), a nationwide longitudinal survey data, we aimed to delineate the prevalence, incidence and risk factors of physical inactivity (PI) among Chinese people aged 45 years and older.

Methods: The CHARLS covered nearly all provinces, autonomous regions, municipalities of mainland China.

The effect of musical interventions in improving short-term pain outcomes following total knee replacement: a meta-analysis and systematic review.

Background: A growing number of patients continue to receive total knee replacement (TKR) surgery. Nevertheless, such surgeries result in moderate to severe postoperative pain and difficulty in managing it. Musical interventions are regarded as a type of multimodal analgesia, achieving beneficial results in other clinical treatments.

High prevalence of patellofemoral osteoarthritis in China: a multi-center population-based osteoarthritis study.

Background: To describe the prevalence and risk factors of patellofemoral osteoarthritis (PFOA) among Chinese residents.

Methods: A multi-center population-based osteoarthritis study was conducted in 2014. Residents aged ≥ 50 years old were recruited using a cluster sampling method.

Porous-coated metaphyseal sleeves and MBT implant for severe bone loss in revision total knee arthroplasty: a mean 2.4-year follow-up.

Background: Porous-coated metaphyseal sleeves are designed to fill bone loss and facilitate osseo-integration when bone loss occurs during revision total knee arthroplasty (TKA). The purpose of this paper was to evaluate the clinical and radiographic outcomes of porous-coated metaphyseal sleeves for severe bone loss in revision TKA.

Methods: Form December 2014 to March 2018, we retrospectively analyzed 36 patients receiving revision TKAs.

Identifying Common Pathogens in Periprosthetic Joint Infection and Testing Drug-resistance Rate for Different Antibiotics: A Prospective, Single Center Study in Beijing.

Objective: The aim of this study is to identify the common microorganisms causing PJI as well as the drug-resistant spectrum for each microorganism, to help orthopaedic surgeons to choose appropriate antibiotics.

Method: One hundred and sixty patients who suffered from failure of primary or revision total hip or knee arthroplasty for different reasons were prospectively recruited. These patients underwent revision or re-revision total hip or knee arthroplasty in our institution between August 2013 to August 2016.
