The potential performance of serum albumin to globulin ratio, albumin and globulin in the diagnosis of periprosthetic joint infection and prediction of reinfection following reimplantation.

Background: This study was conducted to evaluate the performance of serum albumin (ALB), globulin (GLO), and albumin to globulin ratio (AGR) in the diagnosis of PJI and prediction of reinfection following reimplantation in PJI patients who underwent two-stage revision.

Methods: We perform a retrospective data collection on identified patients who underwent revision arthroplasties in our institution from January 2010 to January 2020. A total of 241 patients were stratified into: group A (PJI), group B (aseptic loosening).

Diagnostic accuracy of D-dimer in periprosthetic joint infection: a diagnostic meta-analysis.

Background: Periprosthetic joint infection (PJI) is one of the most devastating complications after total joint replacement (TJA). Up to now, the diagnosis of PJI is still in a dilemma. As a novel biomarker, whether D-dimer is valuable in the diagnosis of PJI remains controversial.

Total Calcanectomy and Bilateral Iliac Bone Autograft Reconstruction for the Treatment of Calcaneal Chondroblastoma Involving a Secondary Aneurysmal Bone Cyst: A Case Report and Literature Review.

Chondroblastoma is a rare, benign, cartilaginous-derived tumor accounting for ∼1% to 2% of all primary bone tumors and almost 9% of all benign bone tumors. In this case report, we describe a patient with chondroblastoma and a secondary aneurysmal bone cyst, with the adjacent talus being mildly affected. The initial diagnosis was giant cell tumor and was then confirmed after computed tomography-assisted biopsy.

Post-THA gait training to improve pelvic obliquity and decrease leg length discrepancy in DDH patients: a retrospective study.

Objectives: To investigate the value of a post-operative gait training program to improve pelvic obliquity (PO) and decrease leg length discrepancy (LLD) for patients with Crowe type I developmental dysplasia of the hip (DDH) undergoing unilateral total hip arthroplasty (THA).

Methods: The prospective group consisted of 35 patients who underwent one-stage unilateral THA. Pre- and post-training PO and LLD were measured for the radiological assessment and Harris Hip Score (HHS) was used for the functional assessment.

One-stage simultaneous hip-preserving surgeries for the management of bilateral femoral head osteonecrosis: a mean 7.0-year follow-up.

Background: A retrospective study was conducted to evaluate and compare the clinical and radiological outcomes of one-stage fibular impaction allografting and vascularized greater trochanter flap autografting for the treatment of bilateral osteonecrosis of the femoral head (ONFH).

Methods: Patients who underwent one-stage aforementioned hip-preserving surgeries due to bilateral ONFH were retrospectively reviewed from January 2008 to December 2013. Sixty-nine patients (138 hips) with a mean age of 31.

Prosthesis design of animal models of periprosthetic joint infection following total knee arthroplasty: A systematic review.

Background: The number of periprosthetic joint infections (PJI) after total knee arthroplasty (TKA) is increasing annually. Animal models have been used to clarify their clinical characteristics and the infection mechanism of pathogenic bacteria, However, since the prosthesis design of animal models is not uniform, it is difficult to simulate the environment of clinical PJI.

Objectives: To retrospect the progress on the prosthesis design of animal models of PJI after TKA and to summarize the criteria for evaluating a clinically representative model of PJI.

A comparative study of cortico-cancellous iliac bone graft with or without the combination of vascularized greater trochanter flap for the management of femoral head osteonecrosis: a minimum 6 years follow-up.

Background: To compare the mid-long-term clinical and radiological outcomes between a combination of cortico-cancellous iliac bone graft with vascularized greater trochanter flap (Group A) and isolate iliac bone graft (Group B) in the treatment of Osteonecrosis of the Femoral Head (ONFH).

Methods: From January 2006 to December 2012, 123 patients (135 hips) who underwent abovementioned hip-preserving surgeries were included for analysis. Clinical outcomes were assessed based on Harris Hip Score (HHS) System and The Western Ontario and McMaster University Index (WOMAC) scores between the preoperative and the last follow-up.
