Comparison of periarticular multidrug injection versus epidural catheter in 55 patients undergoing total hip arthroplasty: A prospective randomized controlled trial.

Introduction: Epidural catheter (EC) and periarticular multidrug injection (PMDI) are widely performed for reducing total hip arthroplasty (THA) postoperative pain. However, the more effective analgesic technique between the two is unclear. Thus, we aimed to answer the following questions: (1) does PMDI contribute to less postoperative pain than EC? (2) is there any difference in side-effect occurrence between the methods? (3) does PMDI provide better functional recovery than EC? (4) is there any difference in inflammatory parameters between the methods?

Hypothesis: PMDI would reduce postoperative pain and side effects, provide better functional recovery, and contribute to lower inflammation compared with EC.

Comparison of short-term outcomes of anterolateral supine approach and posterolateral approach for primary total hip arthroplasty: a retrospective study.

Background: This study aims to evaluate postoperative pain and functional and clinical outcomes of anterolateral supine (ALS) and posterolateral (PL) approaches for primary total hip arthroplasty.

Materials And Methods: We retrospectively examined the joints of 110 patients who underwent primary total hip arthroplasty (THA). The ALS group was compared with the PL group using the pain visual analog scale (VAS) and narcotic consumption as pain outcomes.

Evaluation of muscle volume and degeneration after total hip arthroplasty: a comparison of the posterolateral approach and the anterolateral supine approach.

Background: Muscle strength around the hip after total hip arthroplasty (THA) is crucial for preventing dislocation and limping. This study aimed to assess and compare muscle volume and degeneration after THA using the posterolateral (PL) and anterolateral (AL) approaches.

Methods: Sixty-four hips in 64 patients who underwent primary THA were retrospectively analyzed.

Comparison of periarticular multidrug infiltration and epidural catheter use in total knee arthroplasty: A prospective randomized controlled study.

Purpose: The purpose of this study was to assess the effectiveness of periarticular multidrug infiltration (PMDI) and compare it with that of epidural catheter use.

Methods: Fifty-eight patients (58 joints) who underwent total knee arthroplasty were included in this single-center, prospective, parallel, randomized, controlled trial. Preoperatively, patients were randomly categorized into the PMDI and epidural catheter groups.

A Patient with Pediatric Septic Arthritis of the Hip Complicated with Osteomyelitis Responds to Clindamycin.

A 5-year-old girl was referred to our institution with complaints of right hip pain and fever (39.0°C); blood tests and magnetic resonance imaging (MRI) were performed. Blood biochemical results revealed a high inflammatory reaction.

Clinical outcomes of intramedullary nailing of femoral shaft fractures with third fragments: a retrospective analysis of risk factors for delayed union.

Background: This study retrospectively evaluated the clinical outcomes of intramedullary nailing of femoral shaft fractures with third fragments and analyzed the risk factors for delayed union.

Methods: Retrospective analyses involving 51 patients who underwent intramedullary nailing of femoral shaft fractures with third fragments (AO classification type B, 35 cases; type C, 16 cases) were conducted. Delayed union was defined as either more than 10 months required for callus formation in more than three of the four cortical bone surfaces observed in the frontal and lateral radiographic views or the requirement for additional surgery such as nail conversion or bone transplantation.

Opioid administration via epidural catheter is a risk factor for postoperative nausea and vomiting in total hip arthroplasty: A retrospective study.

Background: Postoperative nausea and vomiting (PONV) may lead to extended hospital stay due to severe discomfort and restriction of patient activity. We retrospectively studied PONV incidence following total hip arthroplasty (THA) to evaluate the effect of opioid administration via epidural catheter.

Methods: Our study included 155 affected joints in 136 patients who underwent a first THA from 2011 to 2016.

Potential utility of cell sheets derived from the anterior cruciate ligament and synovium fabricated in temperature-responsive culture dishes.

Development of tissue-engineered materials to treat anterior cruciate ligament (ACL) injury has been limited by the lack of phenotypic markers. We investigated the feasibility of inducing ACL regeneration using cell sheet technology based on the expression of tenomodulin (TNMD) as an early phenotypic marker of ligaments. ACL remnants, the synovium surrounding cruciate ligaments (SCL), the synovium surrounding the infrapatellar fat pads (SIF), and subcutaneous fat tissue (SCF) were obtained from patients undergoing ACL reconstruction or total knee arthroplasty.

Characterization of chondrocyte sheets prepared using a co-culture method with temperature-responsive culture inserts.

Conventional culture methods using temperature-responsive culture dishes require 4-5 weeks to prepare layered chondrocyte sheets that can be used in articular cartilage repair and regeneration. This study investigated whether the use of synovial tissue obtained from the same joint as the chondrocyte nutritive supply source could more quickly facilitate the preparation of chondrocyte sheets. After culturing derived synoviocytes and chondrocytes together (i.

Cartilage repair in transplanted scaffold-free chondrocyte sheets using a minipig model.

Lacking a blood supply and having a low cellular density, articular cartilage has a minimal ability for self-repair. Therefore, wide-ranging cartilage damage rarely resolves spontaneously. Cartilage damage is typically treated by chondrocyte transplantation, mosaicplasty or microfracture.

Intravenous administration of anti-vascular endothelial growth factor humanized monoclonal antibody bevacizumab improves articular cartilage repair.

Introduction: In this study, we investigate the efficacy of repairing an osteochondral defect in rabbit knee joints by administering bevacizumab, a humanized monoclonal anti-vascular endothelial growth factor (VEGF) antibody.

Methods: An osteochondral defect was created on the patellar groove of 20 Japanese white rabbits that were classified into two recipient groups: group B, administration of bevacizumab (100-mg intravenous injection on the day of surgery and 2 weeks later), and a control group (defect only). Rabbits were killed 1 and 3 months postoperatively.

A large intra-articular loose body in the metacarpophalangeal joint of the middle finger mimicking a calcified tumorous lesion: a case report.

We will report on a case with a large intra-articular loose body in the metacarpophalangeal (MP) joint of the middle finger in a 30-year-old-male, which was mimicking a calcified tumourous lesion adjacent to the palmar side of the metacarpal head. It was easily removed through the palmar approach.
