Long-Term Implant Fracture Rates Following Silicone Metacarpophalangeal Joint Arthroplasty in Rheumatoid Arthritis.

Purpose: The primary objective of this study was to compare the long-term survival rates of silicone metacarpophalangeal (MCP) arthroplasties between two major implants in patients with rheumatoid arthritis, using implant fracture as an end point. We also evaluated the difference in postoperative function between patients with fractured and intact implants as a secondary objective.

Methods: A retrospective cohort study was conducted on 372 fingers of 133 hands that underwent silicone MCP arthroplasty between January 2000 and June 2019 (mean follow-up, 7.

Intensive treatment for the progression of joint damage in rheumatoid arthritis patients with low disease activity or remission.

Objectives: To investigate the effects of intensive treatment on joint damage in patients with rheumatoid arthritis (RA) showing progression of joint damage and low disease activity or remission.

Methods: Eighty-nine patients who had change in the van der Heijde modified total Sharp score (TSS) of >0.5 points at baseline when compared with the score 1 year ago were enrolled and categorized into two groups to receive intensive (intensive group) or current (current group) treatment.

Features of patients with rheumatoid arthritis whose debut joint is a foot or ankle joint: A 5,479-case study from the IORRA cohort.

Background: Foot and ankle joint disorders are serious issues for patients with rheumatoid arthritis (RA). We compared the differences between patients with RA whose first symptom involved a foot or ankle joint (FOOT group) versus other joints (non-FOOT group) within the Institute of Rheumatology, Rheumatoid Arthritis (IORRA) cohort in our institute.

Patients And Methods: In the IORRA survey conducted in April 2016, patients were invited to complete six questionnaires about their first symptom at RA onset, current foot or ankle symptoms, daily living activities, and mental health.

Effects of denosumab treatment on bone mineral density and joint destruction in patients with rheumatoid arthritis.

We aimed to investigate the efficacy of denosumab for rheumatoid arthritis (RA). This study enrolled 70 RA patients who received denosumab 60 mg subcutaneous injection at baseline and at 6 months. Bone mineral densities (BMD) of the lumbar spine, total hip, femoral neck, and hand were measured by dual energy X-ray absorptiometry.

Hip structure analysis by DXA of teriparatide treatment: A 24-month follow-up clinical study.

Objective: The objective of this study was to perform a hip structure analysis (HSA) of teriparatide (TPTD) treatment in women with postmenopausal osteoporosis.

Methods: The study included 96 patients with postmenopausal osteoporosis and received 20 μg TPTD daily. HSA was performed by dual-energy X-ray absorptiometry.

Tramadol hydrochloride/acetaminophen combination versus non-steroidal anti-inflammatory drug for the treatment of perioperative pain after total knee arthroplasty: A prospective, randomized, open-label clinical trial.

Background: While many of the commonly used treatments for perioperative pain after total knee arthroplasty (TKA) have been recognized as effective, there is still insufficient evidence for oral medication. In orthopedics, non-steroidal anti-inflammatory drugs (NSAIDs) have been commonly used for perioperative pain; however, serious adverse events have been reported. Conversely, tramadol hydrochloride/acetaminophen combination (TRAM/APAP) therapy has been shown to reduce pain, particularly for chronic pain in Japan.

Platelet-rich plasma for the reduction of blood loss after total knee arthroplasty: a clinical trial.

Purpose: This study aims to clarify the effect of intra-articular platelet-rich plasma (PRP) in total knee arthroplasty (TKA) in preventing postoperative bleeding.

Methods: There were 315 knees that underwent TKA and were included in this study. The subjects were randomized by paramedical staffs.

The efficacy of abatacept in Japanese patients with rheumatoid arthritis: 104 weeks radiographic and clinical results in clinical practice.

Objective: We aimed to assess the efficacy of abatacept in Japanese patients with rheumatoid arthritis (RA) in clinical practice.

Methods: We examined 92 patients who received abatacept for 104 weeks. Analysis of radiographic efficacy was conducted using van der Heijde-modified total Sharp score (mTSS).

Negative pressure wound therapy and skin grafting for necrotizing fasciitis in a patient with rheumatoid arthritis treated with abatacept: A case report.

Herein, we present a case of necrotizing fasciitis (NF) in a patient with rheumatoid arthritis (RA) treated with abatacept. Cultures of the patient's leg effusion revealed group A Streptococcus. Treatment included antibiological drugs, repeat debridement, negative pressure wound therapy (NPWT), and skin grafting.

Scoliosis-related factors in patients with rheumatoid arthritis: A cross-sectional study.

Objectives: This study aimed to identify the prevalence of scoliosis and scoliosis-related factors of rheumatoid arthritis (RA).

Methods: In this study, 411 patients who underwent coronal total spine and lower limb radiography were enrolled. Patients with a Cobb angle ≥10° were diagnosed with scoliosis.

Validity and responsiveness of a self-administered foot evaluation questionnaire in rheumatoid arthritis.

Objectives: A self-administered foot evaluation questionnaire (SAFE-Q) was developed by the Japanese Society for Surgery of the Foot (JSSF). The aim of this study is to evaluate the validity and responsiveness of the SAFE-Q in patients with rheumatoid arthritis (RA).

Methods: In total, 180 patients with RA answered the SAFE-Q.

Recent trends in orthopedic surgery aiming to improve quality of life for those with rheumatoid arthritis: data from a large observational cohort.

Objective: To describe current trends in the numbers of rheumatoid arthritis (RA)-related surgeries.

Methods: The number of operations was determined for patients with RA in a large observational cohort [Institute of Rheumatology, Rheumatoid Arthritis (IORRA)] enrolled from 2001 to 2012.

Results: The total number of operations peaked in 2002 and gradually decreased thereafter, but began to increase again in 2008.
