We aimed first to summarise minimal clinically important differences
(MCIDs) after total hip (THR) or knee replacement (TKR) in health-related
quality of life (HRQoL), measured using the Short-Form 36 (SF-36).
Secondly, we aimed to improve the precision of MCID estimates by
means of meta-analysis. We conducted a systematic review of English and non-English articles
using MEDLINE, the Cochrane Controlled Trials Register (1960–2011),
EMBASE (1991–2011), Web of Science, Academic Search Premier and
Science Direct. Bibliographies of included studies were searched
in order to find additional studies. Search terms included MCID
or minimal clinically important change, THR or TKR and Short-Form
36. We included longitudinal studies that estimated MCID of SF-36
after THR or TKR.Objectives
Methods
Objectives. Electronic forms of data collection have gained interest in recent
years. In orthopaedics, little is known about patient preference
regarding pen-and-paper or electronic questionnaires. We aimed to
determine whether patients undergoing total hip (THR) or total knee
replacement (TKR) prefer pen-and-paper or electronic questionnaires
and to identify variables that predict preference for electronic
questionnaires. Methods. We asked patients who participated in a multi-centre cohort study
investigating improvement in
To define Patient Acceptable Symptom State (PASS) thresholds
for the Oxford hip score (OHS) and Oxford knee score (OKS) at mid-term
follow-up. In a prospective multicentre cohort study, OHS and OKS were collected
at a mean follow-up of three years (1.5 to 6.0), combined with a
numeric rating scale (NRS) for satisfaction and an external validation
question assessing the patient’s willingness to undergo surgery
again. A total of 550 patients underwent total hip replacement (THR)
and 367 underwent total knee replacement (TKR).Objectives

The Cochrane Collaboration has produced five new reviews relevant to bone and joint surgery since the publication of the last Cochrane Corner These reviews are relevant to a wide range of musculoskeletal specialists, and include reviews in Morton’s neuroma, scoliosis, vertebral fractures, carpal tunnel syndrome, and lower limb arthroplasty.
Osteoarthritis (OA) is characterised by articular cartilage degradation. MicroRNAs (miRNAs) have been identified in the development of OA. The purpose of our study was to explore the functional role and underlying mechanism of miR-138-5p in interleukin-1 beta (IL-1β)-induced extracellular matrix (ECM) degradation of OA cartilage. Human articular cartilage was obtained from patients with and without OA, and chondrocytes were isolated and stimulated by IL-1β. The expression levels of miR-138-5p in cartilage and chondrocytes were both determined. After transfection with miR-138-5p mimics, allele-specific oligonucleotide (ASO)-miR-138-5p, or their negative controls, the messenger RNA (mRNA) levels of aggrecan (ACAN), collagen type II and alpha 1 (COL2A1), the protein levels of glycosaminoglycans (GAGs), and both the mRNA and protein levels of matrix metalloproteinase (MMP)-13 were evaluated. Luciferase reporter assay, quantitative real-time polymerase chain reaction (qRT-PCR), and Western blot were performed to explore whether Forkhead Box C1 (FOCX1) was a target of miR-138-5p. Further, we co-transfected OA chondrocytes with miR-138-5p mimics and pcDNA3.1 (+)-FOXC1 and then stimulated with IL-1β to determine whether miR-138-5p-mediated IL-1β-induced cartilage matrix degradation resulted from targeting FOXC1.Objectives
