Predictive factors for discharge destination after total hip arthroplasty.

Background: This study aimed to investigate factors affecting discharge to an inpatient rehabilitation facility or home following total hip arthroplasty, using a clinical pathway in Japan.

Methods: Five hundred hips with osteoarthritis who underwent unilateral total hip arthroplasty at our institution, with no deviation from the pathway, were included in this retrospective study. The variables were examined by univariate analysis.

Treatment strategy for surgical site infection post posterior lumbar interbody fusion: A retrospective study.

Introduction: Posterior lumbar interbody fusion (PLIF) has been widely used to treat various degenerative spinal diseases. However, surgical site infection (SSI) post-PLIF is often difficult to cure. This study aimed to clarify the difference in clinical course due to the causative organism and develop a treatment strategy for SSI post-PLIF.

Challenges and responses of elective orthopaedic surgery during the second wave of COVID-19.

Background: Elective orthopaedic surgery has been severely curtailed because of coronavirus disease, 2019. There is scant scientific evidence to guide surgeons in assessing the protocols that must be implemented before resuming elective orthopaedic surgery safely after the second wave of the coronavirus disease, 2019.

Methods: A retrospective review of elective orthopaedic surgeries performed between May 15, 2020, and November 20, 2020, was conducted.

Subchondral microfracture of the knee without osteonecrosis after arthroscopic medial meniscectomy.

We report a case of an osteonecrosis-like lesion of the knee that developed shortly after an arthroscopic medial meniscectomy. Clinical presentation, physical findings, and imaging of the knee including magnetic resonance imaging were similar to those of the cases that have been reported as osteonecrosis after meniscectomy. However, histologic analysis of the lesion revealed that there was no osteonecrosis but rather a subchondral microfracture with active callus formation.
