RESUMEN
Despite their proven efficacy for secondary fracture prevention, long-term adherence with oral bisphosphonates is poor. INTRODUCTION: To compare the effectiveness of two interventions on long-term oral bisphosphonate adherence after an upper extremity fragility fracture. METHODS: Community-dwelling participants 50 years or older with upper extremity fragility fractures not previously treated with bisphosphonates were randomized to either a multi-faceted patient and physician educational intervention (the active control arm) vs. a nurse-led case manager (the study arm). Primary outcome was adherence (taking > 80% of prescribed doses) with prescribed oral bisphosphonates at 12 months postfracture between groups; secondary outcomes included rates of primary non-adherence and 24-month adherence. We also compared quality of life between adherent and non-adherent patients. RESULTS: By 12 months, adherence with the initially prescribed bisphosphonate was similar (p = 0.96) in both groups: 38/48 (79.2%) in the educational intervention group vs. 66/83 (79.5%) in the case manager arm. By 24 months, adherence rates were 67% (32/48) in the educational intervention group vs. 53% (43/81) in case managed patients (p = 0.13). Primary non-adherence was 6% (11 patients) in the educational intervention group and 12% (21 patients) in the case managed group (p = 0.07). Prior family history of osteoporosis (aOR 2.1, 95% CI 1.0 to 4.4) and being satisfied with current medical care (aOR 2.3, 95% CI 1.1 to 4.8) were associated with better adherence while lower income (aOR 0.2, 95% CI 0.1 to 0.6, for patients with income < $30,000 per annum) was associated with poorer rates of adherence. There were no differences in health-related quality of life scores at baseline or during follow-up between patients who were adherent and those who were not. CONCLUSION: While both interventions achieved higher oral bisphosphonate adherence compared to previously reported adherence rates in the general population, primary non-adherence and long-term adherence to bisphosphonates were similar in both arms. Adherence was influenced by family history of osteoporosis, satisfaction with current medical care, and income. TRIAL REGISTRATION: ClinicalTrials.gov : NCT01401556.

OBJECTIVE: to determine the extent to which equity factors contributed to eligibility criteria of trials of rehabilitation interventions after hip fracture. We define equity factors as those that stratify healthcare opportunities and outcomes. DESIGN: systematic search of MEDLINE, Embase, CINHAL, PEDro, Open Grey, BASE and ClinicalTrials.gov for randomised controlled trials of rehabilitation interventions after hip fracture published between 1 January 2008 and 30 May 2018. Trials not published in English, secondary prevention or new models of service delivery (e.g. orthogeriatric care pathway) were excluded. Duplicate screening for eligibility, risk of bias (Cochrane Risk of Bias Tool) and data extraction (Cochrane's PROGRESS-Plus framework). RESULTS: twenty-three published, eight protocol, four registered ongoing randomised controlled trials (4,449 participants) were identified. A total of 69 equity factors contributed to eligibility criteria of the 35 trials. For more than 50% of trials, potential participants were excluded based on residency in a nursing home, cognitive impairment, mobility/functional impairment, minimum age and/or non-surgical candidacy. Where reported, this equated to the exclusion of 2,383 out of 8,736 (27.3%) potential participants based on equity factors. Residency in a nursing home and cognitive impairment were the main drivers of these exclusions. CONCLUSION: the generalisability of trial results to the underlying population of frail older adults is limited. Yet, this is the evidence base underpinning current service design. Future trials should include participants with cognitive impairment and those admitted from nursing homes. For those excluded, an evidence-informed reasoning for the exclusion should be explicitly stated. PROSPERO: CRD42018085930.

Fracture liaison services (FLS) are advocated to improve osteoporosis treatment after fragility fracture, but there are few economic analyses of different models. A population-based 1i [=type C] FLS for non-hip fractures was implemented and it costs $44 per patient and it was very cost-effective ($9200 per QALY gained). Small operational changes would convert it from cost-effective to cost-saving. INTRODUCTION: After fragility fracture, <20% of patients receive osteoporosis treatment. FLS are recommended to address this deficit but there are very few economic analyses of different FLS models. Therefore, we conducted an economic analysis of a 1i (=type C) FLS called "Catch a Break (CaB)." METHODS: CaB is a population-based FLS in Alberta, Canada, that case-finds older outpatients with non-traumatic upper extremity, spine, pelvis, or "other" non-hip fractures and provides telephonic outreach and printed educational materials to patients and their physicians. Cost-effectiveness was assessed using Markov decision-analytic models. Costs were expressed in 2014 Canadian dollars and effectiveness based on model simulations of recurrent fractures and quality-adjusted life years (QALYs). Perspective was healthcare payer; horizon was lifetime; and costs and benefits were discounted 3%. RESULTS: Over 1 year, CaB enrolled 7323 outpatients (mean age 67 years, 75% female, 69% upper extremity) at average cost of $44 per patient. Compared with usual care, CaB increased rates of bisphosphonate treatment by 4.3 to 17.5% (p < 0.001). Over their lifetime, for every 10,000 patients enrolled in CaB, 4 hip fractures (14 fractures total) would be avoided and 12 QALYs gained. Compared with usual care, incremental cost-effectiveness of CaB was estimated at $9200 per QALY. CaB was cost-effective in 85% of 10,000 probabilistic simulations. Sensitivity analyses showed if "other" fractures were excluded and intervention costs reduced 25% that CaB would become cost-saving. CONCLUSIONS: A relatively inexpensive population-based 1i (=type C) FLS was implemented in Alberta and it was very cost-effective. If CaB excluded "other" fractures and decreased intervention costs by 25%, it would be cost-saving, as would any FLS that was more effective and less expensive.

We aimed to understand how patients 50 years and older decided to persist with or stop osteoporosis (OP) treatment. Processes related to persisting with or stopping OP treatments are complex and dynamic. The severity and risks and harms related to untreated clinical OP and the favorable benefit-to-risk profile for OP treatments should be reinforced. INTRODUCTION: Older adults with fragility fracture and clinical OP are at high risk of recurrent fracture, and treatment reduces this risk by 50 %. However, only 20 % of fracture patients are treated for OP and half stop treatment within 1 year. We aimed to understand how older patients with new fractures decided to persist with or stop OP treatment over 1 year. METHODS: We conducted a grounded theory study of patients 50 years and older with upper extremity fracture who started bisphosphonates and then reported persisting with or stopping treatment at 1 year. We used theoretical sampling to identify patients who could inform emerging concepts until data saturation was achieved and analyzed these data using constant comparison. RESULTS: We conducted 21 interviews with 12 patients. Three major themes emerged. First, patients perceived OP was not a serious health condition and considered its impact negligible. Second, persisters and stoppers differed in weighting the risks vs benefits of treatments, where persisters perceived less risk and more benefit. Persisters considered treatment "required" while stoppers often deemed treatment "optional." Third, patients could change treatment status even 1-year post-fracture because they re-evaluated severity and impact of OP vs risks and benefits of treatments over time. CONCLUSIONS: The processes and reasoning related to persisting with or stopping OP treatments post-fracture are complex and dynamic. Our findings suggest two areas of leverage for healthcare providers to reinforce to improve persistence: (1) the severity and risks and harms related to untreated clinical OP and (2) the favorable benefit-to-risk profile for OP treatments.

BACKGROUND: In spite of the increasing incidence of total knee arthroplasties (TKA), evidence is limited regarding risk factors for revision. The objective of this scoping review was to identify and assess demographic, surgical and health services factors that may increase the risk for revision surgery following TKA. METHODS: A scoping review was undertaken following an electronic search in MEDLINE (1990 to December 2013), CINAHL (to December 2013), EMBASE (1990 to December 2013) and Web of Science (1990 to December 2013). RESULTS: Of the 4460 articles screened, 42 were included of which 26 articles were based on registry data. Increased risk of revision was associated with demographic factors (younger age, African American), surgical factors related to the primary TKA (uncemented components, implant malalignment, increased surgery duration), and health services (low volume hospitals). CONCLUSIONS: Identifying emerging trends in characteristics of those requiring revision following TKA can help identify those at risk and allocate appropriate resources. Further primary clinical articles on risk factors for revision of TKA are necessary to ensure maximal function and lifespan following TKAs.

This study sought to determine if knowledge regarding the risk for knee injuries and the potential for their prevention is being translated to female adolescent soccer players (13-18 years), their parents, and coaches. Eligible participants in the 2007 indoor soccer season were surveyed to determine their knowledge of the risk for and the potential to prevent knee injuries, and their knowledge of effective prevention strategies, if they felt that injury prevention was possible. Team selection was stratified to be representative of both competitive and recreational level play and age group distributions within the selected soccer association. Of the study subjects, 773/1396 (55.4%) responded to the survey: 408 (53%) players, 292 (38%) parents, and 73 (9%) coaches. Most respondents (538 [71%]) were aware of the risk for knee injury. Coaches and parents were more likely than players to view knee injuries as preventable; however, appropriate prevention strategies were often not identified. Four hundred eighty-four (63.8%) respondents reported that they had never received information on knee injuries. Substantial knowledge gaps regarding knee injury prevention and effective preventative strategies were identified. Given the predominance of knee injuries in female adolescent soccer players, there is an urgent need for knowledge translation of prevention strategies to decrease both incidence and long-term consequences of knee injuries.

BACKGROUND: The objective of this work is to evaluate the performance of a modified quantitative Barrack Cement grading in primary THA. Previous studies demonstrated both poor intraobserver and interobserver reliability which may be due to the qualitative nature of the scale. METHODS: Interobserver reliability of the Barrack Cement Grading System in its original format and then in combination with a quantitative measurement of implant/cement lengths was evaluated on 50 immediate post-operative radiographs of primary cemented arthroplasties. Intraobserver reliability was also assessed on a sub-sample of radiographs. Three evaluators with different skill levels and specialty participated: an arthroplasty surgeon, an orthopaedic resident and a radiologist. Reliability was measured using a weighted kappa coefficient for paired comparisons among the evaluators. RESULTS: Interobserver reliability was poor (κ < 0.10) for all pairings of the Barrack System. The modified quantitative system achieved slight (κ < 0.20) to poor reliability. Intraobserver reliability was dependent on the skill and specialty of the evaluator with maximal values achieved for the experienced arthroplasty surgeon using the modified quantitative system (κ = 0.62). CONCLUSION: Use of the modified scale may improve the reliability of ratings when used by individual experienced arthroplasty surgeons.

OBJECTIVE: Total hip replacement (THR) and total knee replacement (TKR) (arthroplasty) surgery for end-stage osteoarthritis (OA) are ideal candidates for optimization through an algorithmic care pathway. Using a comparative effectiveness study design, we compared the effectiveness of a new clinical pathway (NCP) featuring central intake clinics, dedicated inpatient resources, care guidelines and efficiency benchmarks vs. the standard of care (SOC) for THR or TKR. METHODS: We compared patients undergoing primary THR and TKR who received surgery in NCP vs. SOC in a randomised controlled trial within the trial timeframe. 1,570 patients (1,066 SOC and 504 NCP patients) that underwent surgery within the study timeframe from urban and rural practice settings were included. The primary endpoint was improvement in Western Ontario and McMaster University osteoarthritis index (WOMAC) overall score over 12 months post-surgery. Secondary endpoints were improvements in the physical function (PF) and bodily pain (BP) domains of the Short Form 36 (SF-36). RESULTS: NCP patients had significantly greater improvements from baseline WOMAC scores compared to SOC patients after adjusting for covariates (treatment effect=2.56; 95% confidence interval (CI) [1.10-4.01]). SF-36 BP scores were significantly improved for both hip and knee patients in the NCP (treatment effect=3.01, 95% CI [0.70-5.32]), but SF-36 PF scores were not. Effects of the NCP were more pronounced in knee patients. CONCLUSION: While effect sizes were small compared with major effects of the surgery itself, an evidence-informed clinical pathway can improve health related quality of life (HRQoL) of hip and knee arthroplasty patients with degenerative joint disorder in routine clinical practice for up to 12 months post-operatively.

SUMMARY: Bisphosphonate treatment rates were examined before and after admission to long-term residential care. Bisphosphonate treatment rates were low (16%) pre-admission but doubled after long-term residential care admission (30%). Men were very undertreated for osteoporosis, while a history of falls with injury was not associated with treatment. INTRODUCTION: To determine the rates and independent correlates of bisphosphonate treatment in elderly residents before and after admission to long-term care (LTC) institutions. METHODS: Information was collected from records of 421 residents of four LTC institutions in Edmonton, Alberta, Canada. Osteoporosis-related diagnoses, treatments, and risk factors including falls in LTC and any adulthood fractures were abstracted. Osteoporosis was defined by physician diagnosis or documented fractures of the hip, spine, or upper extremity. Multivariable analyses were undertaken to determine factors independently associated with bisphosphonate treatment. RESULTS: Mean age was 84 ± 8 years and 290 (70%) were female. Overall, 142 (34%) had previous fractures, 170 (41%) had physician-diagnosed osteoporosis, and 227 (54%) residents met the study's clinical definition of osteoporosis. Of those with osteoporosis, 44 (19%) were men. Before admission, 36 (16%) patients with osteoporosis were treated with bisphosphonates; after admission another 31 (14%) were started on bisphosphonates by LTC physicians. Women were far more likely than men to start bisphosphonate treatment [30 (97%) women vs. 1 (3%) man, adjusted odds ratio (aOR) = 9.20 (95% confidence intervals 1.2,70.5)]. Falls with injury were common [72/227 (31%)] but not associated with bisphosphonate treatment (adjusted p value > 0.5). CONCLUSION: Rates of pre-admission bisphosphonate treatment were low, but did double after LTC admission. Women were almost ten times more likely to start bisphosphonate treatment than men, although one fifth of those with documented osteoporosis were men. Although falls cause most fractures, a history of falls with injury was not associated with bisphosphonate treatment. Our findings suggest that targeting men and residents with falls for treatment with bisphosphonates might be warranted.

UNLABELLED: Intravenous bisphosphonates reduce mortality following hip fracture. We determined whether new use of oral bisphosphonates was also associated with reductions in mortality in 209 hip fracture patients. Oral bisphosphonate exposure led to relative reduction of 8% per month of use (p = 0.001) or about a 60% reduction in mortality per year of use. INTRODUCTION: Intravenous bisphosphonates reduce mortality following hip fracture. Using prospectively collected long-term data from a randomized trial of osteoporosis quality improvement for hip fracture, we determined whether new use of oral bisphosphonates was associated with reductions in mortality or the composite outcome of death or new fracture. METHODS: Originally, 220 hip fracture patients were randomized to case manager (n = 110) or usual care followed by facilitated bone mineral density (BMD) testing (n = 110) interventions. All were eligible for bisphosphonate treatment. Post-randomization, we followed patients for 3 years and ascertained bisphosphonate treatment, medication adherence and persistence, all-cause mortality, and new clinical fractures. Proportional hazards analyses with time-varying treatment status were undertaken. RESULTS: The final study cohort included 209 patients: 136 (65%) females, 104 (50%) older than 75 years, 90 (43%) with poor self-reported health, and 38 (18%) underweight. Of these, 76 (36%) had a previous fracture before hip fracture and 132 (81%) had low BMD. A total of 101 (46%) patients started oral bisphosphonates and 65 (64%) remained on treatment at the final evaluation. Overall, 24 (11%) patients died, 19 (9%) had new fractures, and 42 (20%) reached the composite outcome of death or fracture. Compared to no treatment, bisphosphonate exposure was independently associated with reduced mortality (17[16%] vs. 7[7%]; adjusted hazard ratio (aHR) = 0.92 per month treated; 95%CI, 0.88-0.97) and composite endpoints (28[26%] vs. 5[15%]; aHR = 0.94 per month treated; 95%CI, 0.91-0.97). CONCLUSION: Like intravenous bisphosphonates after hip fracture, our study suggests that oral bisphosphonates may be associated with reductions in all-cause mortality.

BACKGROUND: The burden imposed by workplace rotator cuff (RC) injuries has been reasonably defined. However, literature associated with the demographic characteristics and 'best practices' to manage such injuries among workers' compensation (WC) patients is scant. AIMS: To consolidate the existing literature on full-thickness RC tears among WC patients. Subject, shoulder and injury characteristics were examined to determine if and how WC recipients may differ from their non-compensable counterparts. METHODS: A systematic search (databases, clinical practice guideline web resources, conference proceedings and reference lists) revealed 450 abstracts. Two blinded reviewers independently assessed abstracts for inclusion. Sixty abstracts were subsequently included in a blinded full manuscript review. Seventeen of these manuscripts (3.8% of sample; 11 intervention and 6 determinant) were included in the present review. RESULTS: Previous studies demonstrate that operative interventions are appropriate for full-thickness RC tears as substantial gains in range of motion, strength and quality of life were witnessed within the first post-operative year. Non-operative interventions, including workplace-based work hardening, physical therapy and the use of an early referral system, were shown to improve outcomes. Conflicting results exist with respect to determinants such as age and sex. Importantly, WC patients had consistently poorer outcomes than non-WC patients. CONCLUSIONS: Our results show that although WC patients experience substantial benefits from various treatments for full-thickness RC tears, disparities exist between them and their non-WC counterparts. The lack of WC-specific literature limited our results. Larger studies, particularly ones comparing WC patients with their non-compensable counterparts, are crucial to allow for future evidence-based recommendations.

A hip fracture liaison service that was implemented in 2 hospitals in Alberta, Canada, co-managed by a nurse and physician, was cost-effective and improved initiation of osteoporosis medication following hip fracture. PURPOSE/INTRODUCTION: To determine cost-effectiveness of a 3i hip fracture liaison service (H-FLS) with 12-month follow-up, co-managed by a nurse and physician, when implemented into standard practice. METHODS: The cost-effectiveness analysis compared those receiving the H-FLS to a simulated usual care group using a decision analytic model that incorporated Markov processes. We estimated incremental costs and effectiveness (based on quality-adjusted life years (QALYs) gained) using a lifetime horizon and a healthcare payer perspective. The H-FLS program provided data regarding population at risk, treatment rates, persistence, and intervention costs. We also performed deterministic and probabilistic sensitivity analyses. RESULTS: One thousand two hundred fifty-two patients were included in the H-FLS between June 2015 and March 2018; 69% were female; the average age was 80 ± 11 years. Anti-absorptive treatment following fracture was initiated in 59.6% (95% CI: 55.7-63.5) H-FLS patients relative to 20.9% (95% CI: 13.3-28.5%) receiving usual care (from our published work). Based on modeled cohort simulation cost-effectiveness analysis (CEA), every 1000 H-FLS patients would experience 12 fewer hip fractures and 37 fewer total fragility fractures than patients receiving usual care. Over the study horizon, the H-FLS led to only a $54 incremental cost/patient with a modest gain of 8 QALYs/1000 patients. The incremental cost-effectiveness ratio (ICER) of $6750/QALY gained was less than the $27,000 cost-effectiveness threshold. Eliminating the 9-month follow-up resulted in incremental savings of $218/patient while also reducing 6-month follow-ups increased cost-savings to $378/patient. Probabilistic sensitivity analyses suggested that the H-FLS would either be cost-saving (60%) or cost-effective (40%). CONCLUSION: A H-FLS implemented into standard practice significantly improved anti-absorptive medication use; a cohort simulation cost-effectiveness analysis (CEA) suggested that the H-FLS was cost-effective with potential to become cost-savings.

RESUMEN
A hip fracture liaison service that was implemented in 2 hospitals in Alberta, Canada, co-managed by a nurse and physician, was effective for improving initiation of osteoporosis medication following hip fracture. PURPOSE: To examine implementation of an in-patient hip fracture liaison service (H-FLS) to improve osteoporosis medication use after hip fracture using the RE-AIM framework (reach, effectiveness, adoption, implementation, maintenance). METHODS: Using population-based administrative data from 7 quarters before and up to 7 quarters after H-FLS implementation, we examined new starts, continued use, and overall use (new starts + continued use) of osteoporosis medication after hip fracture. A total of 1427 patients 50 years and older that underwent hip fracture surgery at 1 of 2 tertiary hospitals in a Canadian province and survived to 12 months post-fracture were included. We also compared treatment initiation rates by sex and hospital. RESULTS: Of the 1427 patients, 1002 (70.2%) were female (mean age = 79.3 ± 11.9 years) and 425 (29.8%) were male (mean age = 73.8 ± 13.8 years). Based on pre-fracture residence within the health zone, 1101 (69%) were considered eligible (Reach). New starts of osteoporosis medication increased from 24.7% pre- to 43.9% post-implementation of the H-FLS (p < 0.001) (effectiveness). The proportion of patients prescribed osteoporosis medication prior to a hip fracture remained consistent (15.1% pre-; 14.7% post-implementation; p = 0.88) with a resultant improvement in overall medication use from 39.8% pre- to 58.6% post-implementation (p < 0.001). Both sites significantly improved medication initiation (site 1: 27.9% pre- to 40.3% post-implementation; site 2: 19.6% pre- to 50.0% post-implementation; p < 0.001 for both) (adoption). Medication initiation in females improved from 26.0% pre- to 43.4% post-implementation while initiation in males improved from 21.7% pre- to 45.1% post-implementation (p < 0.001[females]; p = 0.001[males]) (implementation). Post-implementation, elevated initiation rates were retained over the 7 quarters (p = 0.81) (maintenance). CONCLUSIONS: An H-FLS based in two tertiary hospital sites significantly improved use of osteoporosis medications after hip fracture in both males and females.

INTRODUCTION: Delays to surgery after hip fracture have been associated with mortality Uncertainty remains as to what timing benchmark should be utilized as a marker of quality of care and how other patient factors might also influence the impact of time to surgery on mortality. The goal of this study was to determine how time to surgery affects 30- and 90-day mortality by age and to explore the impact of preoperative comorbid burden and sex. PARTICIPANTS: We used population-based administrative data from a Canadian province collected from 01April2008 to 31March2015. Of 12,713 Albertans 50-years and older who experienced a hip fracture and underwent surgery within 100 h of admission, 11,996 (94.8%) provided data. METHODS: Time to surgery was analyzed in hours from admission to surgery. Age and the interaction between age and time to surgery were evaluated using logistic regression. Charlson co-morbidity score and sex were also considered in the analysis. Survival was evaluated at 30-and 90-days post hip fracture using a provincial registry. RESULTS: The average age of the cohort was 79.6 ± 11.2 years and 8,412 (70.1%) were female. Overall, 586 (4.9%) patients died within 30-days and 1,023 (8.5%) died within 90-days of hip fracture. Mortality increased significantly with increasing time to surgery (30-day mortality odds ratio [OR] = 1.03; 95%CI 1.01-1.05: 90-day mortality OR = 1.03; 95% CI 1.01-1.04). Mortality also increased substantially with increasing age; those ≥85 years were 19.63 (95% CI 6.83-67.33) and 15.66 (95%CI 7.20-37.16) times the odds more likely to die relative to those between 50-64 years of age at 30-days and 90-days postoperatively respectively. Further, those who were ≥85 years were more significantly affected by increasing time to surgery than those who were 50-64 years of age at both 30-days (p = 0.04) and 90-days (p = 0.025) post-fracture. Males and those with a higher comorbid burden also had higher odds of dying after controlling for time to surgery (p < 0.001) CONCLUSION: Time to surgery following hip fracture may have a differential effect on 30- and 90-day survival dependent on age. Older patients appear to be at higher risk of dying with surgical delays than younger patients.

BACKGROUND: Although excellent long-term results have been reported with cemented tibial fixation, cementless fixation as a means to improve the longevity of total knee prostheses continues to be of interest to clinicians. The purpose of this study was to compare outcomes between cementless tibial fixation with hydroxyapatite and cemented tibial fixation in the first five years following primary total knee arthroplasty. METHODS: We performed a prospective, randomized clinical trial that included eighty-one patients with noninflammatory knee arthritis who underwent primary total knee arthroplasty when they were less than seventy years of age. The subjects were randomized at the time of surgery to be treated with either cementless tibial fixation with hydroxyapatite or cemented tibial fixation. Evaluations were performed preoperatively and at six months, one year, and five years postoperatively by a physical therapist who was blinded to group allocation. Self-reported pain and function, the primary outcomes, were measured with the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) and the RAND 36-Item Health Survey (RAND-36). Complications and revision rates were determined through a review of hospital records and at each patient evaluation. The Knee Society radiographic score was used to evaluate plain radiographs at each assessment. RESULTS: Seventy subjects (86%) completed the five-year assessment. Slightly more pain was reported in the hydroxyapatite group at six months as measured with both the WOMAC and the RAND-36, a difference that disappeared by one year postoperatively. No differences were seen in function, radiographic findings, or complications. No subject required revision of the tibial prosthesis during the study. CONCLUSIONS: At five years postoperatively, there is no difference between cementless tibial fixation with hydroxyapatite and cemented tibial fixation in terms of self-reported pain, function, health-related quality of life, postoperative complications, or radiographic scores.

This study compared the clinical outcomes following mini-open rotator cuff repair (MORCR) between early mobilisation and usual care, involving initial immobilisation. In total, 189 patients with radiologically-confirmed full-thickness rotator cuff tears underwent MORCR and were randomised to either early mobilisation (n = 97) or standard rehabilitation (n = 92) groups. Patients were assessed at six weeks and three, six, 12 and 24 months post-operatively. Six-week range of movement comparisons demonstrated significantly increased abduction (p = 0.002) and scapular plane elevation (p = 0.006) in the early mobilisation group, an effect which was not detectable at three months (p > 0.51) or afterwards. At 24 months post-operatively, patients who performed pain-free, early active mobilisation for activities of daily living showed no difference in clinical outcomes from patients immobilised for six weeks following MORCR. We suggest that the choice of rehabilitation regime following MORCR may be left to the discretion of the patient and the treating surgeon.

BACKGROUND AND PURPOSE: The primary purpose of this randomized controlled trial was to determine which method of mobilization - (1) standardized exercises (SE) and continuous passive motion (CPM), (2) SE and slider board (SB) therapy, using an inexpensive, nontechnical device that requires minimal knee active range of motion (ROM), or (3) SE alone-achieved the maximum degree of knee ROM in the fIrst 6 months following primary total knee arthroplasty (TKA). The secondary purpose was to compare health-related quality of life among these 3 groups. SUBJECTS: The subjects were 120 patients (n=40/group) who received a TEA at a teaching hospital between June 1997 and July 1998 and who agreed to participate in the study. METHODS: Subjects were examined preoperatively, at discharge, and at 3 and 6 months after surgery. The examination consisted of measurement of knee ROM and completion of the Western Ontario and McMaster Universities (WOMAC) Osteoarthritis Index and the Medical Outcomes Study 36-Item Short-Form Health Survey (SF-36). RESULTS: The 3 treatment groups were similar with respect to age, sex, and diagnosis at the start of the study. There were no differences in knee ROM or in WOMAC Osteoarthritis Index or SF-36 scores at any of the measurement intervals. The rate of postoperative complications also was not different among the groups. DISCUSSION AND CONCLUSION: When postoperative rehabilitation regimens that focus on early mobilization of the patient are used, adjunct ROM therapies (CPM and SB) that are added to daily SE sessions are not required. Six months after TEA, patients attain a satisfactory level of knee ROM and function.

In this study we evaluated whether the Instability Severity Index Score (ISIS) and the Western Ontario Shoulder Instability Index (WOSI) could detect those patients at risk of failure following arthroscopic Bankart repair. Between April 2008 and June 2010, the ISIS and WOSI were recorded pre-operatively in 110 patients (87 male, 79%) with a mean age of 25.1 years (16 to 61) who underwent this procedure for recurrent anterior glenohumeral instability. A telephone interview was performed two-years post-operatively to determine whether patients had experienced a recurrent dislocation and whether they had returned to pre-injury activity levels. In all, six (5%) patients had an ISIS > 6 points (0 to 9). Of 100 (91%) patients available two years post-operatively, six (6%) had a recurrent dislocation, and 28 (28%) did not return to pre-injury activity. No patient who dislocated had an ISIS > 6 (p = 1.0). There was no difference in the mean pre-operative WOSI in those who had a re-dislocation and those who did not (p = 0.99). The pre-operative WOSI was significantly lower (p = 0.02) in those who did not return to pre-injury activity, whereas the ISIS was not associated with return to pre-injury activity (p = 0.13). In conclusion, neither the pre-operative ISIS nor WOSI predicted recurrent dislocation within two years of arthroscopic Bankart repair. Patients with a lower pre-operative WOSI were less likely to return to pre-injury activity.

BACKGROUND: The impact of posterior cruciate ligament-substituting and posterior cruciate ligament-retaining devices on the range of motion of the knee following primary total knee arthroplasty is unclear. The primary objective of our study was to compare the range of motion of the knee over the first two postoperative years between subjects who had received the ligament-substituting design and those who had received the ligament-retaining design. Secondarily, pain, function, and health-related quality of life were compared between the two groups. METHODS: We undertook a prospective randomized study of 100 patients with noninflammatory osteoarthritis who were undergoing primary total knee arthroplasty. Patients were randomized at the time of surgery to receive one of the two study prosthesis designs. They were evaluated preoperatively, at the time of hospital discharge, at three months postoperatively, and at up to two years postoperatively by a physical therapist who was blinded to the group allocation. Active knee flexion and extension, measured with a goniometer, were the primary outcome measures. Self-reported pain, function, and health-related quality of life were measured with the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) and the RAND 36-Item Health Survey (RAND-36). Complications and revision rates were determined through hospital record review and at each patient evaluation. RESULTS: Eighty percent (seventy-eight) of the ninety-eight available patients returned for the final assessment. At two years postoperatively, the mean difference between the groups with regard to knee flexion was 0.03 degrees (95% confidence interval, -5.9 degrees to 6.0 degrees ) and the mean difference in knee extension was 1.0 degrees (95% confidence interval, -0.36 degrees to 2.4 degrees ). Ninety-one (93%) of the ninety-eight available patients completed questionnaires at the time of the final assessment. The two treatment groups had similar pain, function, and quality-of-life scores and complication rates. One subject in the cruciate-retaining group required revision, secondary to a deep joint infection, and one subject in the cruciate-substituting group required manipulation to address poor knee flexion. CONCLUSIONS: Overall, the two treatment groups had a similar range of motion of the knee over the initial two-year postoperative time period. A satisfactory range of motion was achieved by three months postoperatively and was maintained at the final assessment.
