Multicenter StudyWhat are the causes of revision total knee arthroplasty in Japan?
There is limited information regarding the cause of revision TKA in Asia, especially Japan. Owing to differences in patient backgrounds and lifestyles, the modes of TKA failures in Asia may differ from those in Western countries. ⋯ The revision burden at the five referral centers in Hokkaido was 3.3%, and the most common cause of revision TKA was mechanical loosening followed by infection. Demographic data such as age and sex might be associated with particular causes of revision TKA.

What are the factors influencing outcome among patients admitted to a hospital with a proximal humeral fracture?
Fracture of the proximal humerus is common in older patients during the decline of their physical health. ⋯ Knowledge of risk factors for inpatient adverse events, mortality, and discharge to facilities can help make treatment decisions, improve overall care, discharge planning, and resource utilization for patients with proximal humeral fractures.

Calcaneal lengthening for planovalgus foot deformity in patients with cerebral palsy.
Calcaneal lengthening has been used to correct planovalgus foot deformities in patients with cerebral palsy (CP). ⋯ Calcaneal lengthening with concomitant peroneus brevis lengthening is an effective procedure for correcting a planovalgus foot deformity in patients with CP. However, for patients with greater than 23° AP talus-first metatarsal angle, 36° lateral talus-first metatarsal angle, and 72% naviculocuboid overlap, additional procedures for medial stabilization, such as tibialis posterior tendon reefing and talonavicular arthrodesis, should be considered as a result of the possibility of undercorrection with calcaneal lengthening alone.

Multicenter Study Comparative StudyRisk of thromboembolism in shoulder arthroplasty: effect of implant type and traumatic indication.
Prior research about symptomatic venous thromboembolism (VTE) after shoulder arthroplasty has not determined whether procedure type (hemiarthroplasty, total shoulder arthroplasty, or reverse shoulder arthroplasty) or surgical indication (traumatic or elective) represent risk factors for VTE after shoulder replacement. ⋯ VTE occurred infrequently in this study sample. These data support future risk and benefit assessment of routine pharmacologic VTE prophylaxis in the perioperative treatment of patients undergoing shoulder arthroplasty, especially in all RSA and traumatic HA subsets, where the risk of VTE may be higher.

ReviewTrends in use of total knee arthroplasty in Korea from 2001 to 2010.
The use of total knee arthroplasty (TKA) has increased substantially in most Western countries. However, the trends in TKA use and changes in demographic characteristics of patients having TKA in Korea remain unclear. ⋯ During the past decade, TKA use in Korea has markedly increased and caught up with the use levels of most developed Western countries. Trends toward consistent growth in elderly patients and higher rates in females were observed. Appropriate healthcare strategies reflecting these trends in demographics are urgently needed in Korea.
