A scoping review and best evidence synthesis for treatment of partial-thickness rotator cuff tears.

BACKGROUND: Rotator cuff disorders include a broad spectrum of pathological conditions including partial-thickness and full-thickness tears. Studies have shown partial-thickness rotator cuff tear (PTRCT) prevalence to be twice that of full-thickness tears. In the working population, PTRCTs are one of the most common causes of shoulder pain and often result in occupational disability due to pain, stiffness, and loss of shoulder function. Treatment of PTRCTs remains controversial. The purpose of this study was to consolidate the existing high-quality evidence on best management approaches in treating PTRCTs using both nonoperative and operative approaches. METHODS: A scoping review with best evidence synthesis was performed as per the Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews. MEDLINE (OVID), EMBASE (OVID), Cochrane Library (Wiley), SCOPUS, Web of Science Core Collection, CINAHL Plus with Full Text (EBSCOhost), PubMed Central, and Science Direct were searched from 2000 to March 3, 2023. Level 1 studies, and systematic reviews and meta-analyses that included level 1 and 2 studies, were included. RESULTS: The search yielded 8276 articles. A total of 3930 articles were screened after removing 4346 duplicates. Application of inclusion criteria resulted in 662 articles that were selected for full-text review. Twenty-eight level 1 studies, 1 systematic review, 4 meta-analyses, and 1 network meta-analyses were included in the best evidence synthesis. Nonoperative strategies included injections (ie, platelet-rich plasma, corticosteroid, prolotherapy, sodium hyaluronate, anesthetic, and atelocollagen), exercise therapy, and physical agents. Operative interventions consisted of débridement, shaving of the tendon and footprint, transtendon repair, and traditional suture anchor repair techniques with and without tear completion. Both nonoperative and operative strategies demonstrated effectiveness at managing pain and functional outcome for PTRCTs. The evidence supports the effectiveness of surgical intervention in treating PTRCTs regardless of arthroscopic technique. CONCLUSION: The results of this scoping review do not support superiority of operative over nonoperative management and suggest that both strategies can be effective at managing pain and functional outcome for PTRCTs. Surgery, however, is the most invasive and costly approach, with the highest risk of complications such as infection. Other variables such as patient expectation, treating practitioner bias, or preference may change which modalities are offered and in what sequence.

Elective surgery in ankle and foot disorders-best practices for management of pain: a guideline for clinicians.

PURPOSE: Complex elective foot and ankle surgeries are often associated with severe pain pre- and postoperatively. When inadequately managed, chronic postsurgical pain and long-term opioid use can result. As no standards currently exist, we aimed to develop best practice pain management guidelines. METHODS: A local steering committee (n = 16) surveyed 116 North American foot and ankle surgeons to understand the "current state" of practice. A multidisciplinary expert panel (n = 35) was then formed consisting of orthopedic surgeons, anesthesiologists, chronic pain physicians, primary care physicians, pharmacists, registered nurses, physiotherapists, and clinical psychologists. Each expert provided up to three pain management recommendations for each of the presurgery, intraoperative, inpatient postoperative, and postdischarge periods. These preliminary recommendations were reduced, refined, and sent to the expert panel and "current state" survey respondents to create a consensus document using a Delphi process conducted from September to December 2020. RESULTS: One thousand four hundred and five preliminary statements were summarized into 51 statements. Strong consensus (≥ 80% respondent agreement) was achieved in 53% of statements including the following: postsurgical opioid use risk should be assessed preoperatively; opioid-naïve patients should not start opioids preoperatively unless non-opioid multimodal analgesia fails; and if opioids are prescribed at discharge, patients should receive education regarding importance of tapering opioid use. There was no consensus regarding opioid weaning preoperatively. CONCLUSIONS: Using multidisciplinary experts and a Delphi process, strong consensus was achieved in many areas, showing considerable agreement despite limited evidence for standardized pain management in patients undergoing complex elective foot and ankle surgery. No consensus on important issues related to opioid prescribing and cessation highlights the need for research to determine best practice.

RéSUMé: OBJECTIF: Les chirurgies électives complexes du pied et de la cheville sont souvent associées à une douleur intense avant et après l'opération. Lorsque cette douleur est mal prise en charge, elle peut entraîner une douleur postopératoire chronique et une consommation d'opioïdes à long terme. Comme il n'existe actuellement aucune norme, nous avons cherché à élaborer des lignes directrices sur les meilleures pratiques en matière de prise en charge de la douleur. MéTHODE: Un comité directeur local (n = 16) a interrogé 116 chirurgiens nord-américains spécialistes du pied et de la cheville pour comprendre « l'état actuel ¼ de la pratique. Un groupe d'experts multidisciplinaire (n = 35) a ensuite été formé, composé de chirurgiens orthopédistes, d'anesthésiologistes, de médecins spécialistes de la douleur chronique, de médecins de soins primaires, de pharmaciens, d'infirmières autorisées, de physiothérapeutes et de psychologues cliniciens. Chaque expert a fourni jusqu'à trois recommandations de prise en charge de la douleur pour chacune des périodes suivantes : en préchirurgie, en peropératoire, pendant l'hospitalisation postopératoire et après le congé. Ces recommandations préliminaires ont été réduites, affinées et envoyées au groupe d'experts et aux répondants du sondage sur « l'état actuel ¼ afin de créer un document de consensus à l'aide d'une méthode de Delphi réalisée entre septembre et décembre 2020. RéSULTATS: Mille quatre cent cinq déclarations préliminaires ont été résumées en 51 énoncés. Un consensus fort (≥ 80 % des répondants étaient d'accord) a été atteint concernant 53 % des énoncés, notamment les suivants : le risque de consommation postopératoire d'opioïdes devrait être évalué avant l'opération; les patients naïfs aux opioïdes ne devraient pas commencer à prendre des opioïdes avant l'opération, à moins que l'analgésie multimodale non opioïde n'échoue; et si des opioïdes sont prescrits au congé, les patients devraient être informés de l'importance de réduire leur consommation d'opioïdes. Il n'y avait pas de consensus concernant le sevrage des opioïdes en période préopératoire. CONCLUSION: À l'aide d'experts multidisciplinaires et d'une méthode de Delphi, un fort consensus a été atteint dans de nombreux aspects, montrant un accord considérable malgré des données probantes limitées pour une prise en charge standardisée de la douleur chez les patients subissant une chirurgie élective complexe du pied et de la cheville. L'absence de consensus sur des questions importantes liées à la prescription et à l'interruption des opioïdes souligne la nécessité de recherches pour déterminer les pratiques exemplaires.

Impact of Depressive Symptomology on Pain and Function during Recovery after Total Joint Arthroplasty.

OBJECTIVES: To determine the effect of preoperative depressive symptoms on patient-reported function and pain following total joint arthroplasty (TJA) after controlling for potential confounding factors; how depressive symptoms changed after TJA; and the impact of postoperative depressive symptoms on recovery. METHODS: A prospective cohort study undertaken in a metropolitan region in Canada enrolled 710 participants; 622 (87%) had complete 6-month data. Participants completed standardized measures preoperatively and at 1, 3, and 6 months postoperatively. The primary outcome was Western Ontario McMaster Osteoarthritis Index (WOMAC) pain and function. Three groups were created: depressive symptoms absent (n = 573, 82%), possible depressive symptoms (n = 58, 8%), and probable depressive symptoms (n = 68, 10%) using the Center for Epidemiologic Scale for Depression score. Risk-adjusted analyses examined the association between WOMAC change and the preoperative Center for Epidemiologic Scale for Depression score. RESULTS: After risk adjustment, preoperative possible and probable depressive symptomology was associated with postoperative WOMAC pain scores that were 7.6 and 11.7 points, respectively, worse and WOMAC function scores that were 8.8 and 14.3 points, respectively, worse than those without preoperative depressive symptoms. Depressive symptoms improved postoperatively; by 6 months post-TJA, only 34 (5%) participants screened as having probable depressive symptoms, whereas only 13(2%) had possible depressive symptoms. Postoperative WOMAC pain and function scores improved, but they were negatively affected by possible and probable depressive symptoms. CONCLUSIONS: Although depressive symptoms improve postoperatively, preoperative depressive symptoms, especially for those with probable depressive symptomology, may negatively affect postoperative pain and functional recovery even after risk adjustment.

Effect of preoperative long-term opioid therapy on patient outcomes after total knee arthroplasty: an analysis of multicentre population-based administrative data.

Background: Up to 40% of patients are receiving opioids at the time of total knee arthroplasty (TKA) in the United States despite evidence suggesting opioids are ineffective for pain associated with arthritis and have substantial risks. Our primary objective was to determine whether preoperative opioid users had worse knee pain and physical function outcomes 12 months after TKA than patients who were opioid-naive preoperatively; our secondary objective was to determine the prevalence of opioid use before and after TKA in Alberta, Canada. Methods: In this retrospective analysis of population-based data, we identified adult patients who underwent TKA between 2013 and 2015 in Alberta. We used multivariable linear regression to examine the association between preoperative opioid use and Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) pain and physical function scores 12 months after TKA, adjusting for potentially confounding variables. Results: Of the 1907 patients, 592 (31.0%) had at least 1 opioid dispensed before TKA, and 124 (6.5%) were classified as long-term opioid users. Long-term opioid users had worse adjusted WOMAC pain and physical function scores 12 months after TKA than patients who were opioid-naive preoperatively (pain score ß = 7.7, 95% confidence interval [CI] 4.0 to 11.6; physical function score ß = 7.8, 95% CI 4.0 to 11.6; p < 0.001 for both). The majority (89 ([71.8%]) of patients who were long-term opioid users preoperatively were dispensed opioids 180-360 days after TKA, compared to 158 (12.0%) patients who were opioid-naive preoperatively. Conclusion: A substantial number of patients were dispensed opioids before and after TKA, and patients who received opioids preoperatively had worse adjusted pain and functional outcome scores 12 months after TKA than patients who were opioidnaive preoperatively. These results suggest that patients prescribed opioids preoperatively should be counselled judiciously regarding expected outcomes after TKA.

Contexte: Jusqu'à 40 % des patients se font prescrire des opioïdes lors d'une chirurgie pour prothèse totale du genou (PTG) aux États-Unis, et ce, malgré des données selon lesquelles les opioïdes sont inefficaces pour la douleur associée à l'arthrite et comportent des risques substantiels. Notre objectif principal était de déterminer si les patients qui utilisaient déjà des opioïdes en période préopératoire obtenaient des résultats plus négatifs aux plans de la douleur et du fonctionnement 12 mois après leur PTG, comparativement aux patients qui ne prenaient pas d'opioïdes avant leur intervention; notre objectif secondaire était de mesurer la prévalence du recours aux opioïdes avant et après la PTG en Alberta, au Canada. Méthodes: Dans cette analyse rétrospective menée sur des données de population, nous avons identifié les patients adultes soumis à une PTG entre 2013 et 2015 en Alberta. Nous avons utilisé un modèle de régression linéaire multivarié pour examiner le lien entre l'utilisation d'opioïdes en période préopératoire et les scores de douleur et de fonctionnement à l'échelle WOMAC (Western Ontario and McMaster Universities Osteoarthritis Index) 12 mois après la PTG, en tenant compte de potentielles variables de confusion. Résultats: Sur les 1907 patients, 592 (31,0 %) ont reçu au moins 1 opioïde avant leur PTG, et 124 (6,5 %) en étaient considérés des utilisateurs de longue date. Les utilisateurs d'opioïdes de longue date présentaient de moins bons scores WOMAC ajustés pour les domaines de douleur et de fonctionnement 12 mois après la PTG, comparativement aux patients qui n'en prenaient pas avant l'intervention (score de douleur ß = 7,7, intervalle de confiance [IC] de 95 % 4,0 à 11,6; score de fonctionnement ß = 7,8, IC de 95 % 4,0 à 11,6; p < 0,001 pour les 2 domaines). La majorité (89 [71,8 %]) des patients utilisateurs d'opioïdes de longue date avant l'intervention se sont fait servir des opioïdes 180­360 jours après la PTG, comparativement à 158 patients (12,0 %) qui n'en prenaient pas avant l'intervention. Conclusion: Un nombre substantiel de patients ont reçu des opioïdes avant et après la PTG, et ceux qui en prenaient avant l'intervention présentaient des scores de douleur et de fonctionnement ajustés plus défavorables 12 mois après la PTG, comparativement aux patients qui n'en prenaient pas avant l'intervention. Selon ces résultats, il faut adresser des conseils judicieux aux patients qui sont déjà sous opioïdes en période préopératoire et les informer des résultats possibles de la PTG.

Validity of Tools to Measure Physical Activity in Older Adults Following Total Knee Arthroplasty.

Few validated tools exist for measuring physical activity following total knee arthroplasty (TKA) despite the importance of returning to sufficient levels of physical activity post-TKA to achieve health benefits. This study examined the validity of two clinical measures-the Fitbit, a commercially available personal activity monitor, and the Community Healthy Activities Model Program for Seniors (CHAMPS), a self-report questionnaire-compared with a reference standard accelerometer, the SenseWearTM Armband (SWA). At 6-month post-TKA, 47 participants wore the Fitbit and SWA for 4 days and then completed the CHAMPS. Moderate-to-good correlation was observed between the Fitbit and SWA for steps (intraclass correlation coefficient [ICC] = .79), energy expenditure (ICC = .78), and energy expenditure <3 METS (ICC = .79). Poor-to-moderate correlation was observed between the CHAMPS and SWA (ICC = .43) with the questionnaire reporting lower daily energy expenditures than the SWA. Results showed that Fitbit may be a reasonable measurement tool to measure steps and energy expenditures in older adults following TKA.

Perioperative pain management and chronic postsurgical pain after elective foot and ankle surgery: a scoping review.

PURPOSE: Chronic postsurgical pain (CPSP) can occur after elective mid/hindfoot and ankle surgery. Effective treatment approaches to prevent the development of CPSP in this population have not been extensively investigated. The impact of multimodal strategies to prevent CPSP following elective mid/hindfoot surgery is unknown because of both the heterogeneity of acute pain management and the lack of a recognized definition particular to this surgery. This review aimed to identify and evaluate current pain management strategies after elective mid/hindfoot and ankle surgery. SOURCES: Manual and electronic searches (MEDLINE, Embase, and Cochrane Library) were conducted of literature published between 1990 and July 2017. Comparative studies of adults undergoing elective mid/hindfoot and ankle surgery were included. Two reviewers independently reviewed studies and assessed their methodological quality. PRINCIPAL FINDINGS: We found seven randomized-controlled trials meeting our inclusion criteria. Interventions focused on regional anesthesia techniques such as continuous popliteal sciatic and femoral nerve blockade. Participants were typically followed up to 48 hr postoperatively. Only one study assessed pain six months following elective mid/hindfoot and ankle surgery. CONCLUSION: There is an overwhelming lack of evidence regarding CPSP and its management for patients undergoing elective mid/hindfoot and ankle surgery. The lack of a recognized and standard definition of CPSP after this group of surgeries precludes accurate and consistent evaluation.

RéSUMé: OBJECTIF: La douleur chronique post-chirurgicale (DCPC) peut survenir après une chirurgie non urgente de la section moyenne ou postérieure du pied, ou de la cheville. Les approches thérapeutiques efficaces pour prévenir l'apparition de DCPC dans cette population n'ont pas été examinées en profondeur. L'impact des stratégies multimodales pour prévenir la DCPC après une chirurgie non urgente de la section moyenne ou postérieure du pied est inconnu, tant en raison de l'hétérogénéité de la prise en charge de la douleur aiguë que du manque de définition reconnue spécifique à ce type de chirurgie. Ce compte-rendu a pour objectif d'identifier et d'évaluer les stratégies de prise en charge de la douleur actuellement utilisées après une chirurgie de la section moyenne ou postérieure du pied, ou de la cheville. SOURCES: Des recherches manuelles et électroniques (MEDLINE, Embase, et Librairie Cochrane) ont été menées dans la littérature publiée entre 1990 et juillet 2017. Les études comparatives portant sur des adultes subissant une chirurgie non urgente de la section moyenne ou postérieure du pied ou de la cheville ont été incluses. Deux chercheurs ont indépendamment passé en revue les études et évalué leur qualité méthodologique. CONSTATATIONS PRINCIPALES: Nous avons trouvé sept études randomisées contrôlées respectant nos critères d'inclusion. Les interventions se concentraient sur des techniques d'anesthésie régionale tels que les blocs continus des nerfs sciatiques poplités et fémoraux. Les participants bénéficiaient en général d'un suivi jusqu'à 48 h après l'opération. Une seule étude a évalué la douleur six mois après une chirurgie non urgente de la section moyenne ou postérieure du pied ou de la cheville. CONCLUSION: L'absence de données probantes est colossale en ce qui touche à la DCPC et à sa prise en charge pour les patients subissant une chirurgie non urgente de la partie moyenne ou postérieure et de la cheville. L'absence de définition normalisée et reconnue de la DCPC après ce type de chirurgie en exclut toute évaluation précise et cohérente.

Preoperative opioid use is associated with worse patient outcomes after Total joint arthroplasty: a systematic review and meta-analysis.

BACKGROUND: A significant number of patients use opioids prior to total joint arthroplasty (TJA) in North America and there is growing concern that preoperative opioid use negatively impacts postoperative patient outcomes after surgery. This systematic review and meta-analysis evaluated the current evidence investigating the influence of preoperative opioid use on postoperative patient-reported outcomes (PRO) after total joint arthroplasty. METHODS: A systematic search was performed using Ovid, Embase, Cochrane Library, Scopus, Web of Science Core Collection, CINAHL on February 15th, 2018. Studies reporting baseline and postoperative PRO among those prescribed preoperative opioids and those who were not prior to total knee and hip arthroplasty were included. Standardized mean differences (SMD) in absolute difference and relative change in PRO measures between the two groups was calculated using random effect models. RESULTS: Six studies were included (n = 7356 patients); overall 24% of patients were prescribed preoperative opioids. Patients with preoperative opioid use had worse absolute postoperative PRO scores when compared to those with no preoperative opioid use (standardized mean difference (SMD) -0.53, 95% Confidence interval (CI) -0.75, - 0.32, p < 0.0001). When relative change in PRO score was analyzed, as measured by difference between postoperative and preoperative PRO scores, there was no group differences (SMD -0.26, 95% CI -0.56, 0.05, p = 0.10). CONCLUSION: Patients prescribed preoperative opioids may attain worse overall pain and function benefits after TJA when compared to opioid-naïve patients, but do still benefit from undergoing TJA. These results suggest preoperative opioid users should be judiciously counselled regarding potential postoperative pain and function improvements after TJA.

A comparison of outcomes between Canada and the United States in patients recovering from hip fracture repair: secondary analysis of the FOCUS trial.

OBJECTIVE: To determine if adjusted mortality, walking ability or return home differed after hip fracture surgery between Canada and the USA. DESIGN: Secondary analysis of the Functional Outcomes in Cardiovascular Patients Undergoing Surgical Hip Fracture Repair (FOCUS) trial data. SETTING: Data were collected from 47 American and Canadian hospitals. PARTICIPANTS: Overall, 2016 subjects with a hip fracture (USA = 1222 (60.6%); Canada = 794 (39.4%)) were randomized to a liberal or restrictive transfusion strategy. Subjects were 50 years and older, with cardiovascular disease and/or risk factors and hemoglobin <100 g/L within 3 days post-surgery. The average age was 82 years and 1527(76%) subjects were females. INTERVENTION: Demographics, health status and health services data were collected up to 60 days post-surgery and mortality to a median of 3 years post-surgery. MAIN OUTCOMES: Mortality, inability to walk and return home. RESULTS: US subjects had higher adjusted mortality than Canadians at 30 days (odds ratio = 1.78; 95% confidence interval: 1.09-2.90), 60 days (1.53; 1.02-2.29) and up to 3 years (hazard ratio = 1.25; 1.07-1.45). There were no differences in adjusted outcomes for walking ability or return home at 30 or 60 days post-surgery. Median hospital length of stay was longer (P < 0.0001) in Canada (9 days; interquartile range: 5-18 days) than the US (3 days; 2-5 days). US subjects (52.9%) were more likely than Canadians (16.8%) to be discharged to nursing homes for rehabilitation (P < 0.001). CONCLUSIONS: Adjusted survival favored Canadians post hip fracture while walking ability and return home were not different between countries. The reason(s) for mortality differences warrant further investigation.

A Randomized Clinical Trial Comparing Posterior Cruciate-Stabilizing vs Posterior Cruciate-Retaining Prostheses in Primary Total Knee Arthroplasty: 10-Year Follow-Up.

BACKGROUND: This 10-year follow-up compares health-related quality of life (HRQL) and reoperations in 100 subjects who were randomized to receive posterior cruciate ligament substituting (PS) or posterior cruciate ligament retaining (CR) total knee arthroplasty. We previously reported 2-year results. METHODS: Subjects were enrolled preoperatively and randomized at surgery. Subjects completed HRQL questionnaires at all evaluation points. Subjects were re-evaluated at 2 and 10 years with reoperations determined through regional medical record review and patient report. RESULTS: Over 10 years, 25 (25%) subjects died, 2 subjects were revised and withdrew, and 11 (11%) subjects were lost to follow-up. Of survivors, 62 of 75 (83%) were evaluated at 10 years. Twenty-eight (37%) subjects provided HRQL, radiographic, and reoperation status, 28 (37%) subjects completed HRQL evaluations and reoperation status only, and 6 (8%) subjects provided radiographic and reoperation follow-up. Both groups retained good HRQL between 2 and 10 years with no group differences noted (P > .35). One revision (CR subject), secondary to deep joint infection, occurred within 2 years with 1 further revision (PS subject) occurring at 3 years postoperatively. One subject (PS subject) required manipulation under anesthesia within 3 months of surgery. Four subjects required late patellar resurfacing (1 CR subject, 3 PS subjects) but were retained in the 10-year evaluation. Overall, reoperations were not significantly different between groups (P = .26). CONCLUSION: Over 10 years postoperatively, both the PS and CR total knee arthroplasty performed well with subjects reporting acceptable levels of HRQL up to 10 years postoperatively; low levels of revision or reoperation were reported in both groups.

A critical review of the long-term disability outcomes following hip fracture.

BACKGROUND: Hip fractures are an increasingly common consequence of falls in older people that are associated with a high risk of death and reduced function. This review aims to quantify the impact of hip fracture on older people's abilities and quality of life over the long term. METHODS: Studies were identified through PubMed and Scopus searches and contact with experts. Cohort studies of hip fracture patients reporting outcomes 3 months post-fracture or longer were included for review. Outcomes of mobility, participation in domestic and community activities, health, accommodation or quality of life were categorised according to the World Health Organization's International Classification of Functioning and synthesised narratively. Risk of bias was assessed according to four items from the Strengthening the Reporting of Observational Studies in Epidemiology (STROBE) statement. RESULTS: Thirty-eight studies from 42 publications were included for review. Most followed a clearly defined sample from the time of fracture. Hip fracture survivors experienced significantly worse mobility, independence in function, health, quality of life and higher rates of institutionalisation than age matched controls. The bulk of recovery of walking ability and activities for daily living occurred within 6 months after fracture. Between 40 and 60 % of study participants recovered their pre-fracture level of mobility and ability to perform instrumental activities of daily living, while 40-70 % regained their level of independence for basic activities of daily living. For people independent in self-care pre-fracture, 20-60 % required assistance for various tasks 1 and 2 years after fracture. Fewer people living in residential care recovered their level of function than those living in the community. In Western nations, 10-20 % of hip fracture patients are institutionalised following fracture. Few studies reported impact on participation in domestic, community, social and civic life. CONCLUSIONS: Hip fracture has a substantial impact on older peoples' medium- to longer-term abilities, function, quality of life and accommodation. These studies indicate the range of current outcomes rather than potential improvements with different interventional approaches. Future studies should measure impact on life participation and determine the proportion of people that regain their pre-fracture level of functioning to investigate strategies for improving these important outcomes.

Total joint arthroplasty: practice variation of physiotherapy across the continuum of care in Alberta.

BACKGROUND: Comprehensive and timely rehabilitation for total joint arthroplasty (TJA) is needed to maximize recovery from this elective surgical procedure for hip and knee arthritis. Administrative data do not capture the variation of treatment for rehabilitation across the continuum of care for TJA, so we conducted a survey for physiotherapists to report practice for TJA across the continuum of care. The primary objective was to describe the reported practice of physiotherapy for TJA across the continuum of care within the context of a provincial TJA clinical pathway and highlight possible gaps in care. METHOD: A cross-sectional on-line survey was accessible to licensed physiotherapists in Alberta, Canada for 11 weeks. Physiotherapists who treated at least five patients with TJA annually were asked to complete the survey. The survey consisted of 58 questions grouped into pre-operative, acute care and post-acute rehabilitation. Variation of practice was described in terms of number, duration and type of visits along with goals of care and program delivery methods. RESULTS: Of the 80 respondents, 26 (33 %) stated they worked in small centres or rural settings in Alberta with the remaining respondents working in two large urban sites. The primary treatment goal differed for each phase across the continuum of care in that pre-operative phase was directed at improving muscle strength, functional activities were commonly reported for acute care, and post-acute phase was directed at improving joint range-of-motion. Proportionally, more physiotherapists from rural areas treated patients in out-patient hospital departments (59 %), whereas a higher proportion in urban physiotherapists saw patients in private clinics (48 %). Across the continuum of care, treatment was primarily delivered on an individual basis rather than in a group format. CONCLUSIONS: Variation of practice reported with pre-and post-operative care in the community will stimulate dialogue within the profession as to what is the minimal standard of care to provide patients undergoing TJA.

Radiographic sclerotic contour loss in the identification of glenoid bone loss.

PURPOSE: Quantification of glenoid bone loss guides surgical management in the setting of anterior shoulder instability. Glenoid defects resulting in ≥20 % articular area loss require bony reconstruction. The objective of this study was to evaluate the utility of sclerotic glenoid contour loss on true anteroposterior radiography in the detection of varying quantities of simulated glenoid bone loss using a cadaveric model. METHODS: Eight cadaveric scapulae with full radiographic sclerotic contour were osteotomized to produce glenoid surface area reductions of 10-50 %. Radiography was performed initially and following each osteotomy, and assessed by an orthopedic surgeon and radiologist twice. Quantity of glenoid loss was compared using Fisher's exact test. Sensitivity, specificity, and reliability analyses were performed. RESULTS: On the first radiographic review, sclerotic contour loss was detected in 6 out of 8 scapulae with 50 % area loss, but only 1 out of 8 scapulae with 20 % area loss. There was a significantly higher proportion of radiographs containing sclerotic contour loss for defects with 50 % area loss compared to those with 0-25 % loss (p ≤ 0.02). In the detection of ≥20 % area loss, sclerotic contour loss had a sensitivity of 33-43 % and specificity of 88-100 %. Moderate inter-observer reliability (Cohen's kappa value of 0.42-0.53) and intra-observer reliability (kappa value of 0.46-0.58) were found. CONCLUSION: Radiographic sclerotic contour loss is commonly observed in radiographs of scapulae with 40-50 % glenoid area loss and less often with smaller lesions. However, this finding lacks utility in discerning specific quantifications of glenoid bone loss. In a clinical setting, sclerotic contour loss suggests the presence of a large glenoid defect that may require bony reconstruction. However, an intact sclerotic contour does not rule out significant bone loss.

A Randomized Trial Comparing Ceramic-on-Ceramic Bearing vs Ceramic-on-Crossfire-Polyethylene Bearing Surfaces in Total Hip Arthroplasty.

BACKGROUND: Bearing surfaces in total hip arthroplasty (THA) may affect implant longevity and hence patient outcomes. This randomized clinical trial determined how ceramic-on-ceramic (CERAMIC) bearing THA affected joint-specific pain, function, and stiffness and prosthesis fixation/longevity over 10 postoperative years compared with ceramic-on-highly-crosslinked-polyethylene (POLYETHYLENE) bearing THA. This is a follow-up to previously reported 5-year outcomes. METHODS: Subjects aged <61 years were randomized to CERAMIC (n = 48) or POLYETHYLENE (n = 44) THA. Subjects were assessed using the Western Ontario McMaster Osteoarthritis Index and the RAND 12-Item Health Survey preoperatively, and at 1, 5, and 10 years postoperatively. Plain radiographs were evaluated at 10 years for fixation, and medical records were reviewed for revisions. RESULTS: Of 92 subjects, 6 (7%) died within 10 years; 68 (79%) survivors provided radiographic and/or clinical follow-up at 10 years postoperatively. Improvements seen at 5 years in both the Western Ontario McMaster Osteoarthritis Index and RAND 12-Item Health Survey were retained at 10 years with no group differences (P > .48). There were no failures or loss of fixation related to bearing surfaces/wear in either group. Over 10 years, 3 subjects in the POLYETHYLENE group had revisions that were related to recurrent dislocation; 2 revisions were performed within 2 years of surgery, and one further subject underwent revision at 7 years postoperatively. CONCLUSIONS: This is one of the first randomized clinical trials to examine 10-year outcomes between CERAMIC and POLYETHYLENE bearing THAs. Both bearing surfaces performed well out to 10 years in subjects who were <61 years at time of surgery.

Does Topical Anesthetic Reduce Pain During Intraosseous Pin Removal in Children? A Randomized Controlled Trial.

BACKGROUND: The purpose of this study was to determine the effectiveness of topical liposomal lidocaine in reducing the pain perceived by children undergoing percutaneous intraosseous pin (PP) removal in the outpatient orthopaedic clinic. METHODS: A triple-blinded, randomized, placebo-controlled clinical trial comparing topical liposomal lidocaine to a placebo was conducted at the Stollery Children's Hospital between September 2008 and February 2011. Subjects undergoing the removal of PP in the orthopaedic outpatient clinic between ages 3 and 16 years were recruited. A computer-generated variable-block randomization scheme was used to determine each subject's group assignment. Pain was recorded just before randomization and immediately after the procedure using the Oucher Scale (for subjects) and a 10-cm Visual Analog Scale (for parents and an observing orthopaedic technician). In a subset of individuals, follow-up telephone calls were made 24 hours postprocedure to inquire about any adverse event from the use of the topical liposomal lidocaine. Data were analyzed using the Student t test. RESULTS: Of a total of 296 recruited subjects, complete data were available on 281 subjects (140 intervention and 141 control). There were no significant differences between the 2 groups with regards to baseline characteristics, including preprocedure pain scores. Although postprocedure pain scores demonstrated an increase in pain in both groups (2.3 points in the treatment group and 2.0 points in the placebo group), no statistically significant difference was seen in postprocedure pain scores between groups (P=0.81). No adverse events were observed or reported. CONCLUSIONS: Topically applied liposomal lidocaine was not effective in reducing pain during this procedure, compared with a placebo. However, this study demonstrates that PP removal is a painful procedure in children. Given the large volume of patients who undergo this procedure and the long-term consequences of experiencing painful procedures in childhood, it is important to find safe and fast-acting methods to decrease procedural pain associated with PP removal.

Imaging methods for quantifying glenoid and Hill-Sachs bone loss in traumatic instability of the shoulder: a scoping review.

BACKGROUND: Glenohumeral instability is a common problem following traumatic anterior shoulder dislocation. Two major risk factors of recurrent instability are glenoid and Hill-Sachs bone loss. Higher failure rates of arthroscopic Bankart repairs are associated with larger degrees of bone loss; therefore it is important to accurately and reliably quantify glenohumeral bone loss pre-operatively. This may be done with radiography, CT, or MRI; however no gold standard modality or method has been determined. A scoping review of the literature was performed to identify imaging methods for quantifying glenohumeral bone loss. METHODS: The scoping review was systematic in approach using a comprehensive search strategy and standardized study selection and evaluation. MEDLINE, EMBASE, Scopus, and Web of Science were searched. Initial selection included articles from January 2000 until July 2013, and was based on the review of titles and abstracts. Articles were carried forward if either reviewer thought that the study was appropriate. Final study selection was based on full text review based on pre-specified criteria. Consensus was reached for final article inclusion through discussion amongst the investigators. One reviewer extracted data while a second reviewer independently assessed data extraction for discrepancies. RESULTS: Forty-one studies evaluating glenoid and/or Hill-Sachs bone loss were included: 32 studies evaluated glenoid bone loss while 11 studies evaluated humeral head bone loss. Radiography was useful as a screening tool but not to quantify glenoid bone loss. CT was most accurate but necessitates radiation exposure. The Pico Method and Glenoid Index method were the most accurate and reliable methods for quantifying glenoid bone loss, particularly when using three-dimensional CT (3DCT). Radiography and CT have been used to quantify Hill-Sachs bone loss, but have not been studied as extensively as glenoid bone loss. CONCLUSIONS: Radiography can be used for screening patients for significant glenoid bone loss. CT imaging, using the Glenoid Index or Pico Method, has good evidence for accurate quantification of glenoid bone loss. There is limited evidence to guide imaging of Hill-Sachs bone loss. As a consensus has not been reached, further study will help to clarify the best imaging modality and method for quantifying glenohumeral bone loss.

Bone Mineral Density Changes in the Hip and Spine of Men and Women 1-Year After Primary Cemented Total Knee Arthroplasty: Prospective Cohort Study.

This study evaluated age- and sex-adjusted changes in total hip and spine bone mineral density (BMD) within 1 year of total knee arthroplasty (TKA) using a prospective, longitudinal cohort with a one-year follow-up. Preoperatively, subjects underwent routine bone mineral densitometry of their hip and spine, which was repeated 12 months postoperatively. Of 108 subjects, 97 (90%) completed BMD testing. Total hip BMD decreased significantly over time (1.80% change, P<0.001) with females losing more than males (P<0.001). The pattern was similar, but attenuated in the spine. Subjects undergoing primary cemented TKA had significant bone loss in the hip within 12 months, beyond that expected with age.

A randomized pilot study of a comprehensive postoperative exercise program compared with usual care following primary total hip arthroplasty in subjects less than 65 years of age: feasibility, selection of outcome measures and timing of assessment.

BACKGROUND: Total Hip Arthroplasty (THA) is being used more commonly in younger higher demand patients. The purpose of this randomized pilot study was to explore a) feasibility of comprehensive postoperative rehabilitation compared to usual care following primary THA in subjects <65 years, b) appropriate outcome measures including performance-based measures and c) timing of assessments. METHODS: 21 subjects who underwent primary THA were randomized to receive a three-month out-patient rehabilitation program (Intervention) or usual postoperative care (Control). Subjects were assessed preoperatively, six-weeks postoperatively (Pre-intervention) and four and 12 months postoperatively (Post-intervention). Self-report measures were the Western Ontario McMaster Osteoarthritis Index (WOMAC) and Rand 36-Item Health Survey (RAND-36). Performance-based measures included lower extremity strength, walking speed and endurance, and gait laboratory assessment. RESULTS: Ten Control and 11 Intervention subjects with an average age of 53.4 (SD9.3) years were randomized. All Intervention subjects completed the program without adverse effects. Although no statistically significantly results were reported, four months postoperatively, Intervention subjects had clinically important differences (CID) in strength compared with Control subjects. Walking endurance, WOMAC and RAND scores improved significantly with no CID noted between groups. Ten (48%) subjects reported a ceiling effect on the WOMAC (9 (43%) subjects on Pain; 1 (5%) subject on Function). No group CID were noted in gait measures. CONCLUSIONS: Our recommendations would be that performance-based strength measures should be considered for the primary outcome in this younger cohort. Because of the ceiling effects with WOMAC Pain, a different pain measure is indicated. Other more challenging functional performance-based tests should be considered such as a more prolonged endurance test. There is merit in one-year follow-up as strength improved after four months in both groups.

'I do hope more people can benefit from it.': The qualitative experience of individuals living with osteoarthritis who participated in the GLA:D™ program in Alberta, Canada.

INTRODUCTION: The Good Life with osteoArthritis: Denmark (GLA:DTM) is an evidence-based program designed for individuals with symptomatic hip and knee osteoarthritis (OA). This program has reported improvement in pain, quality of life and self-efficacy, as well as delays in joint replacement surgery for adults with moderate to severe hip or knee OA. Evaluations of GLA:DTM implementation in several countries have focused on effectiveness, training, and feasibility of the program primarily from the provider perspective. Our objective was to examine how the GLA:DTM program was perceived and experienced by individuals with hip and knee OA to inform on-going program refinement and implementation. METHODS: Thirty semi-structured telephone interviews were conducted with participants who completed the GLA:DTM program in Alberta. An interpretive description approach was used to frame the study and thematic analysis was used to code the data and identify emergent themes and sub-themes associated with participants' experience and perception of the GLA:DTM program. RESULTS: Most participants had a positive experience of the GLA:DTM program and particularly enjoyed the group format, although some participants felt the group format prevented one-on-one support from providers. Three emergent themes related to acceptability were identified: accessible, adaptable, and supportive. Participants found the program to be accessible in terms of location, cost, and scheduling. They also felt the program was adaptable and allowed for individual attention and translatability into other settings. Finally, most participants found the group format to be motivating and fostered connections between participants. CONCLUSION: The GLA:DTM program was perceived as acceptable by most participants, yet the group format may not be useful for all individuals living with OA. Recommended improvements included adapting screening to identify those suited for the group format, providing program access earlier in the disease progression trajectory, modifying educational content based on participants' knowledge of OA and finally, providing refresher sessions after program completion.
