Abstract
OBJECTIVE The objective of this systematic review of the literature was to identify the predictors of functional outcome after total hip arthroplasty (THA). METHOD A systematic literature search in Web of Science, CINAHL, EMBASE and PubMed was conducted on 23 June 2015. The articles were selected based on their quality, relevance and measurement of the predictive factor. The level of evidence of all studies was determined using the GRADE rating scheme. RESULTS The initial search resulted in 1092 citations. After application of the inclusion and exclusion criteria, 33 articles met our eligibility criteria and were graded. Included studies were classified as level of evidence low (11), moderate (17) or high (5). Of the included studies, 18 evaluated body mass index (BMI), 17 evaluated preoperative physical functions, 15 evaluated age, 15 evaluated gender and 13 evaluated comorbidity. There was strong evidence suggesting an association between BMI, age, comorbidity, preoperative physical functions and mental health with functional outcome after THA. There was weak evidence suggesting an association between quadriceps strength and education with functional outcome after THA. The evidence was inconsistent for associations with gender and socioeconomic status and functional outcome following THA. We found limited evidence suggesting that alcohol consumption, vitamin D insufficiency and allergies were predictors of functional outcome following THA. CONCLUSIONS We have identified multiple predictors of functional outcome after THA, which will enable general practitioners and orthopaedic surgeons to better predict the improvement in physical functioning for their patients with THA. They can use this information to provide patient-specific advice regarding the referral for THA and the expected outcomes after THA. Further research with consistent measurement tools, outcomes and duration of follow-up across studies is needed to confirm the influence of these factors.

Revista espanola de cirugia ortopedica y traumatologia. 2015;(2):73-90
Abstract
OBJECTIVE To analyze the efficacy and safety of preventive analgesia in patients undergoing hip or knee arthroplasty due to osteoarthritis. METHODS A systematic literature review was performed, using a defined a sensitive strategy on Medline, Embase and Cochrane Library up to May 2013. The inclusion criteria were: patients undergoing knee and/or hip arthroplasty, adults with moderate or severe pain (≥4 on a Visual Analog Scale). The intervention, the use (efficacy and safety) of pharmacological treatment (preventive) close to surgery was recorded. Oral, topical and skin patch drugs were included. Systematic reviews, meta-analysis, controlled trials and observational studies were selected. RESULTS A total of 36 articles, of moderate quality, were selected. The patients included were representative of those undergoing knee and/or hip arthroplasty in Spain. They had a mean age >50 years, higher number of women, and reporting moderate to severe pain (≥4 on a Visual Analog Scale). Possurgical pain was mainly evaluated with a Visual Analog Scale. A wide variation was found as regards the drugs used in the preventive protocols, including acetaminophen, classic NSAID, Cox-2, opioids, corticosteroids, antidepressants, analgesics for neuropathic pain, as well as others, such as magnesium, ketamine, nimodipine or clonidine. In general, all of them decreased post-surgical pain without severe adverse events. CONCLUSIONS The use or one or more pre-surgical analgesics decreases the use of post-surgical drugs, at least for short term pain.

Arthroscopy : the journal of arthroscopic & related surgery : official publication of the Arthroscopy Association of North America and the International Arthroscopy Association. 2015;(4):785-92
Abstract
PURPOSE This article discusses current evidence in nutraceuticals and viscosupplementation uses in osteoarthritis (OA) treatment. METHODS A search was carried out to identify systematic reviews, randomized controlled trials, review articles, and original articles (PubMed and Cochrane Database) about nutraceuticals and viscosupplementation. The keywords used were nutraceuticals, glucosamine, chondroitin, diacerein, avocado, soybean unsaponifiables, nutraceuticals, and viscosupplementation, independently or combined with the terms "review" and "randomized." RESULTS Glucosamine hydrochloride has no effect on pain management, although the sulfate formulation has a moderate effect. Diacerein leads to pain relief, with a superior carryover effect when compared with placebo. Avocado and soybean unsaponifiables may have positive effects on knee and hip OA, but long-term results could not be confirmed. Despite the American Academy of Orthopaedic Surgeons' recommendation against the use of hyaluronic acid in OA, some systematic reviews found some benefits in the knee. CONCLUSIONS There is no evidence that nutraceuticals or viscosupplementation influences OA's natural progression. However, some of these agents seem to reduce pain and improve function. LEVEL OF EVIDENCE Level IV, systematic review of studies with Level I through Level IV evidence.

Compositional MRI techniques for evaluation of cartilage degeneration in osteoarthritis.
Guermazi, A, Alizai, H, Crema, MD, Trattnig, S, Regatte, RR, Roemer, FW
Osteoarthritis and cartilage. 2015;(10):1639-53
Abstract
Osteoarthritis (OA), a leading cause of disability, affects 27 million people in the United States and its prevalence is rising along with the rise in obesity. So far, biomechanical or behavioral interventions as well as attempts to develop disease-modifying OA drugs have been unsuccessful. This may be partly due to antiquated imaging outcome measures such as radiography, which are still endorsed by regulatory agencies such as the United States Food and Drug Administration (FDA) for use in clinical trials. Morphological magnetic resonance imaging (MRI) allows unparalleled multi-feature assessment of the OA joint. Furthermore, advanced MRI techniques also enable evaluation of the biochemical or ultrastructural composition of articular cartilage relevant to OA research. These compositional MRI techniques have the potential to supplement clinical MRI sequences in identifying cartilage degeneration at an earlier stage than is possible today using morphologic sequences only. The purpose of this narrative review is to describe compositional MRI techniques for cartilage evaluation, which include T2 mapping, T2* Mapping, T1 rho, dGEMRIC, gagCEST, sodium imaging and diffusion weighted imaging (DWI). We also reviewed relevant clinical studies that have utilized these techniques for the study of OA. The different techniques are complementary. Some focus on isotropy or the collagen network (e.g., T2 mapping) and others are more specific in regard to tissue composition, e.g., gagCEST or dGEMRIC that convey information on the GAG concentration. The application and feasibility of these techniques is also discussed, as they will play an important role in implementation in larger clinical trials and eventually clinical practice.

Abstract
OBJECTIVES Osteoarthritis (OA) is the most common form of arthritis with a clear genetic component. To identify novel loci associated with hip OA we performed a meta-analysis of genome-wide association studies (GWAS) on European subjects. METHODS We performed a two-stage meta-analysis on more than 78,000 participants. In stage 1, we synthesised data from eight GWAS whereas data from 10 centres were used for 'in silico' or 'de novo' replication. Besides the main analysis, a stratified by sex analysis was performed to detect possible sex-specific signals. Meta-analysis was performed using inverse-variance fixed effects models. A random effects approach was also used. RESULTS We accumulated 11,277 cases of radiographic and symptomatic hip OA. We prioritised eight single nucleotide polymorphism (SNPs) for follow-up in the discovery stage (4349 OA cases); five from the combined analysis, two male specific and one female specific. One locus, at 20q13, represented by rs6094710 (minor allele frequency (MAF) 4%) near the NCOA3 (nuclear receptor coactivator 3) gene, reached genome-wide significance level with p=7.9×10(-9) and OR=1.28 (95% CI 1.18 to 1.39) in the combined analysis of discovery (p=5.6×10(-8)) and follow-up studies (p=7.3×10(-4)). We showed that this gene is expressed in articular cartilage and its expression was significantly reduced in OA-affected cartilage. Moreover, two loci remained suggestive associated; rs5009270 at 7q31 (MAF 30%, p=9.9×10(-7), OR=1.10) and rs3757837 at 7p13 (MAF 6%, p=2.2×10(-6), OR=1.27 in male specific analysis). CONCLUSIONS Novel genetic loci for hip OA were found in this meta-analysis of GWAS.

Osteoarthritis year in review 2014: rehabilitation and outcomes.
Maly, MR, Robbins, SM
Osteoarthritis and cartilage. 2014;(12):1958-88
Abstract
OBJECTIVE To highlight research studies examining rehabilitation for hip and knee osteoarthritis (OA), as well as the outcome measures used to assess treatment efficacy, published in 2013. DESIGN A systematic search was performed in Medline, CIHAHL and Embase databases from January to December 2013. The search was limited to 2013, human studies, and English. Rehabilitation intervention studies included were prospective controlled designs. The Grading of Recommendations Assessment, Development and Evaluation (GRADE) system was used to evaluate the quality of evidence. First, individual articles were rated for quality. Second, articles were grouped based on outcome: OA disease markers, pain, physical function (self-reported, performance), and health. RESULTS Of 503 titles reviewed, 36 studies were included. The outcome measures related to OA disease markers were organized into subthemes of anthropometrics, biomechanics and physiology. The quality of evidence was of moderate, high, and low quality for anthropometric, biomechanical and physiological measures respectively. These studies supported the use of diet for weight loss combined with exercise. Bodies of evidence that showed the efficacy of exercise and passive strategies (thermal/electrical modalities, traction, manual therapy) for reducing pain were of low and moderate quality respectively. The evidence supporting diet and exercise, physiotherapy, and passive strategies to improve physical function was of moderate quality. Evidence supporting exercise to improve psychological factors was of moderate quality. CONCLUSIONS Exercise combined with diet for weight loss should be the mainstays of rehabilitation for people with knee and hip OA to provide benefit to OA disease markers, pain, physical function, and health.

Determinants of MSK health and disability: lifestyle determinants of symptomatic osteoarthritis.
Fransen, M, Simic, M, Harmer, AR
Best practice & research. Clinical rheumatology. 2014;(3):435-60
Abstract
It is frequently considered that, for many people, symptomatic osteoarthritis involving the lower limb joints is a largely preventable 'lifestyle disease'. The purpose of this review is to evaluate the most recent scientific evidence examining the effect of various lifestyle factors, such as physical activity, obesity, diet, smoking, alcohol and injury, on the development of symptomatic knee or hip osteoarthritis. The strengths and weaknesses of various studies are discussed, the magnitude of any demonstrated risks presented and current overall conclusions drawn.

Evolution in hip resurfacing design and contemporary experience with an uncemented device.
Spencer, RF
The Journal of bone and joint surgery. American volume. 2011;:84-8
Abstract
The concepts of surface replacement of the hip and metal-on-metal articulation date back to the 1930s, and recent hip resurfacing designs have been more successful than their predecessors. Experience with the Cormet device followed initial collaboration with Mr. Derek McMinn. Both hybrid implants (a cementless cup and a cemented head) and entirely cementless implants, inserted with use of a variety of surgical approaches, yielded good results, with the cementless option increasing in popularity. The indications for hip resurfacing have become better understood, with the procedure considered most suitable for young and middle-aged males with a high activity profile. In addition, revision surgery, if necessary, has been associated in most cases with bone and soft-tissue conservation. Caution should be exercised when treating small individuals (especially females) and individuals with accompanying diagnoses other than osteoarthritis (such as hip dysplasia), for whom other bone-conserving options may be more appropriate to avoid an adverse reaction to metal debris. Correct implant placement during hip resurfacing is of critical importance.

Non-pharmacological approaches for the treatment of osteoarthritis.
Rannou, F, Poiraudeau, S
Best practice & research. Clinical rheumatology. 2010;(1):93-106
Abstract
For the most part, non-pharmacological approaches are recommended for osteoarthritis treatment. This recommendation is based mainly on biomechanical observations leading to a modulation of the symptomatic loading joint. Approaches include orthoses, insoles, exercise, diet and patient education. The approach used for each osteoarthritis site must be adapted for the individual patient. Here, we use an evidence-based approach, including the European League Against Rheumatism (EULAR) and Osteoarthritis Research Society International (OARSI) recommendations, to summarise the non-pharmacological treatments available for knee, hip and hand osteoarthritis and to help the physician in daily clinical practice.

Abstract
BACKGROUND Osteoarthritis is the most common form of joint disease and the leading cause of pain and disability in the elderly. S-Adenosylmethionine may be a viable treatment option but the evidence about its effectiveness and safety is equivocal. OBJECTIVES We set out to compare S-Adenosylmethionine (SAMe) with placebo or no specific intervention in terms of effects on pain and function and safety outcomes in patients with knee or hip osteoarthritis. SEARCH STRATEGY We searched CENTRAL, MEDLINE, EMBASE, CINAHL and PEDro up to 5 August 2008, checked conference proceedings and reference lists, and contacted authors. SELECTION CRITERIA Randomised or quasi-randomised controlled trials that compared SAMe at any dosage and in any formulation with placebo or no intervention in patients with osteoarthritis of the knee or hip. DATA COLLECTION AND ANALYSIS Two independent authors extracted data using standardised forms. We contacted investigators to obtain missing outcome information. We calculated standardised mean differences (SMDs) for pain and function, and relative risks for safety outcomes. We combined trials using inverse-variance random-effects meta-analysis. MAIN RESULTS Four trials including 656 patients were included in the systematic review, all compared SAMe with placebo. The methodological quality and the quality of reporting were poor. For pain, the analysis indicated a small SMD of -0.17 (95% CI -0.34 to 0.01), corresponding to a difference in pain scores between SAMe and placebo of 0.4 cm on a 10 cm VAS, with no between trial heterogeneity (I(2) = 0). For function, the analysis suggested a SMD of 0.02 (95% CI -0.68 to 0.71) with a moderate degree of between-trial heterogeneity (I2 = 54%). The meta-analyses of the number of patients experiencing any adverse event, and withdrawals or drop-outs due to adverse events, resulted in relative risks of 1.27 (95% CI 0.94 to 1.71) and 0.94 (95% CI 0.48 to 1.86), respectively, but confidence intervals were wide and tests for overall effect were not significant. No trial provided information concerning the occurrence of serious adverse events. AUTHORS' CONCLUSIONS The current systematic review is inconclusive, hampered by the inclusion of mainly small trials of questionable quality. The effects of SAMe on both pain and function may be potentially clinically relevant and, although effects are expected to be small, deserve further clinical evaluation in adequately sized randomised, parallel-group trials in patients with knee or hip osteoarthritis. Meanwhile, routine use of SAMe should not be advised.
