Complex distal femoral fractures in the fragile elderly patient treated by distal femoral replacement: A report of three cases / Fractura de fémur distal compleja en el paciente frágil y anciano tratada mediante reemplazo femoral distal: reporte de 3 casos

Complex distal femoral fracture (DFF) in the elderly patient is an infrequent but challenging scenario. In these fragile patients, DFF is associated with a high rate of medical complications and mortality. The optimum treatment remains controversial. Our aim is to propose our standard treatment, describe our results and discuss its clinical relevance. We describe three cases of elderly and fragile patients with multiple comorbidities who suffered a complex DFF after low energy trauma. They were successfully treated through a primary arthroplasty with distal femoral replacement (DFR). All the three patients presented early full weight-bearing mobilization (average time to first ambulation was five days), good functional outcome (mean knee range of motion was 103°) and short hospital length of stay (mean of ten days). According to our experience, primary arthroplasty with DFR could be a good therapeutic option for complex DFF in elderly patients.(AU)

La fractura femoral distal (FFD) compleja en el paciente anciano es infrecuente, pero su manejo es un desafío. En estos pacientes frágiles, la FFD se asocia a un elevado riesgo de complicaciones médicas y mortalidad. Su tratamiento óptimo sigue siendo controvertido. El objetivo del estudio es proponer nuestro tratamiento estándar, describir nuestros resultados y discutir su relevancia clínica. Reportamos 3 casos de pacientes ancianos y frágiles con múltiples comorbilidades que sufrieron una FFD compleja a causa de un traumatismo de baja energía. Fueron tratados con éxito mediante un reemplazo femoral distal (RFD). Los 3 pacientes presentaron una movilización precoz con carga completa (la media hasta la primera deambulación fue 5 días), buenos resultados funcionales (la media de rango de movimiento de la rodilla fue 103̊) y una estancia hospitalaria breve (media de 10 días). Según nuestra experiencia, la artroplastia primaria podría ser una buena elección terapéutica para las FFD complejas en los pacientes ancianos.(AU)

The effect of care transition pathway implementation on patients undergoing joint replacement during the COVID-19 pandemic: a quasi-experimental study from a tertiary care hospital orthopedic department in Beijing, China.

BACKGROUND: The coronavirus disease (COVID-19) pandemic has had a massive impact on individuals globally. The Chinese government has formulated effective response measures, and medical personnel have been actively responding to challenges associated with the epidemic prevention and control strategies. This study aimed to evaluate the effect of the implementation of a care transition pathway on patients that underwent joint replacement during the COVID-19 pandemic. METHODS: A quasi-experimental study was designed to evaluate the effect of implementing a care transition pathway for patients who underwent joint replacement during the COVID-19 pandemic in the orthopedic department of a tertiary care hospital in Beijing, China. Using a convenient sampling method, a total of 96 patients were selected. Of these, 51 patients who had undergone joint replacement in 2019 and received treatment via the routine nursing path were included in the control group. The remaining 45 patients who underwent joint replacement during the COVID-19 epidemic in 2020 and received therapy via the care transition pathway due to the implementation of epidemic prevention and control measures were included in the observation group. The quality of care transition was assessed by the Care Transition Measure (CTM), and patients were followed up 1 week after discharge. RESULTS: The observation group was determined to have better general self-care preparation, written planning materials, doctor-patient communication, health monitoring, and quality of care transition than the control group. CONCLUSIONS: A care transition pathway was developed to provide patients with care while transitioning through periods of treatment. It improved the patient perceptions of nursing quality. The COVID-19 pandemic is a huge challenge for health professionals, but we have the ability to improve features of workflows to provide the best possible patient care.

Mobility Technicians: A Viable Solution to Early Ambulation of Total Joint Replacement Patients.

BACKGROUND: Early ambulation of patients with total joint replacement (TJR) has been shown to improve outcomes while reducing length of stay and postoperative complications. Limited physical therapy (PT) resources and late-in-the-day cases may challenge day-of-surgery (POD0) ambulation. At our institution, a Mobility Technician (MT) program, composed of specially trained nurse's aides, was developed to address this issue. PURPOSE: The purpose of this study was to compare the effectiveness of the MT model with a traditional PT model in the early ambulation of patients with TJR. METHODS: Patients undergoing unilateral primary TJR at a single institution between June 1, 2014, and October 31, 2018, were included. Ambulation measures were retrospectively assessed between pre- and post-MT program groups. RESULTS: This study included 11,777 patients with TJR. Following the MT program, number of POD0 ambulations, POD0 ambulation distance, and total distance ambulated all increased while time-to-first ambulation decreased. CONCLUSION: Preliminary analyses indicate that the MT program has been successful in the early ambulation of patients with TJR.

Chronic Resistance Exercise Improves Functioning and Reduces Toll-Like Receptor Signaling in Elderly Patients With Postoperative Deconditioning.

OBJECTIVE: Elderly patients continue to experience low levels of mobility during and following postoperative hospitalization that lead to persistent physical decline. Therefore, here we compared chronic resistance (CR) exercise against chronic aerobic (CA) exercise in ameliorating postoperative functioning and reducing proinflammatory muscular Toll-like receptor (TLR)-associated signaling in elderly postoperative patients. METHODS: We conducted a prospective, randomized trial comparing the effects of 3 exercise programs (CR, CA, and CR + CA) in 66 elderly patients recovering from recent hip, femur, or pelvic fracture repair surgery. The primary outcomes were changes in anatomic/physical performance parameters (ie, maximal oxygen intake, endurance, quadriceps cross-sectional area, and maximum knee-extensor force). The secondary outcomes were changes in TLR/nuclear factor kappa beta signaling pathway marker expression. RESULTS: Three of the 4 anatomic/physical performance parameters significantly improved for the CR and CR + CA cohorts. Muscular expression of myeloid differentiation primary response gene 88, transforming growth factor beta-activated kinase 1 (TLR signaling pathway markers), p50, p65, tumor necrosis factor α, and interleukin 6 (nuclear factor kappa beta signaling pathway markers) all showed significant reductions after CR and CR + CA. Serum expression of 2 key TLR4 ligands, heat shock protein 70 and serum amyloid A, also showed significant reductions after CR and CR + CA. CONCLUSIONS: Three months of CR or CR + CA improves maximal oxygen consumption, quadriceps cross-sectional area, and maximum knee-extensor force while lowering muscular proinflammatory signaling markers in elderly adults with postoperative deconditioning.

Impact of Self-Care and Mobility on One or More Post-Acute Care Transitions.

Objective: To investigate the association between functional status and post-acute care (PAC) transition(s). Methods: Secondary analysis of 2013-2014 Medicare data for individuals aged ≥66 years with stroke, lower extremity joint replacements, and hip/femur fracture discharged to one of three PAC settings (inpatient rehabilitation facilities, skilled nursing facilities, and home health agencies). Functional scores were co-calibrated into a 0-100 scale across settings. Multilevel logistic regression was used to test the partition of variance (%) and the probability of PAC transition attributed to the functional score in the initial PAC setting. Results: Patients discharged to inpatient rehabilitation facilities with higher function were less likely to use additional PAC. Function level in an inpatient rehabilitation facility explained more of the variance in PAC transitions than function level while in a skilled nursing facility. Discussion: The function level affected PAC transitions more for those discharged to an inpatient rehabilitation facility than to a skilled nursing facility.

Joint replacement (primary): hip, knee and shoulder

This guideline covers care before, during and after a planned knee, hip or shoulder replacement. It includes recommendations to ensure that people are given full information about their options for surgery, including anaesthesia. It offers advice for healthcare professionals on surgical procedures and ensuring safety during operations. It also offers guidance on providing support and rehabilitation before and after surgery.

Using the knowledge-to-action framework with joint arthroplasty patients to improve the quality of care transition: a quasi-experimental study.

BACKGROUND: Total joint arthroplasty is a mature and effective treatment for end-stage osteoarthritis. Assisting patients in completing the transition of the perioperative period and improving their satisfaction are important aspects of quality of care. This study aimed to investigate an intervention to improve the quality of care transition for joint arthroplasty patients informed by the knowledge-to-action (KTA) framework. METHODS: In this quasi-experimental study, a total of 160 patients who underwent joint arthroplasty at a tertiary hospital from September to November 2018 and January to March 2019 were selected as participants using convenience sampling. The control group received routine medical care, while the observation group received medical care based on the KTA framework. Transitional care quality was assessed by the Care Transition Measure (CTM), with follow-up 1 week after discharge. RESULTS: The observation group fared significantly better than the control group on general self-care preparation and written plan dimensions, as well as the quality of care transition. There was no significant difference in doctor-patient communication or health monitoring. CONCLUSIONS: The KTA framework provides a logical, valuable tool for clinical work. Using the KTA framework for joint arthroplasty patients helps to improve the quality of care transition, which is worth promoting.

Exploring the relationship between body mass index, mental health and outcomes of a regional physiotherapy-led post-arthroplasty review clinic.

OBJECTIVE: To determine whether 12-month hip and knee outcomes of a regional arthroplasty clinic were comparable to results from metropolitan-based clinics, and to explore a possible relationship between body mass index and depression to identify groups at risk of not achieving optimal outcomes. DESIGN: A prospective observational study. SETTING: A regional physiotherapy-led post-arthroplasty review clinic. PARTICIPANTS: Patients after hip or knee replacement. INTERVENTIONS: Patients underwent either total hip or total knee joint arthroplasty. MAIN OUTCOME MEASURES: SF-12 Health Survey, Oxford Hip/Knee Scale, 10-minute walk test, knee range of motion, body mass index and the Hospital Anxiety and Depression Scale. RESULTS: Physical outcomes were comparable to those reported by metropolitan-based clinics. People with a high body mass index showed most improvement in the severity of depression compared to those with a lower body mass index. CONCLUSION: It is important to consider the long-term effects of obesity on arthroplasty outcomes.

Health professionals' perceptions of the allied health role in the acute setting following hip and knee joint replacement surgery: a qualitative study.

Purpose: To describe health professionals' perceptions of the role of allied health during the acute phase following elective lower limb joint replacement surgery to inform the development of efficient allied health service models.Methods: This was a qualitative descriptive study conducted using semi-structured focus groups and thematic analysis. Participants were 25 medical, nursing, and allied health professionals working on two orthopaedic wards in a tertiary hospital in Victoria, Australia. Focus groups elicited staff perceptions regarding the aims and roles of acute allied health intervention following hip and knee replacement, how these services are currently provided, and how these services can best be provided. This study was undertaken alongside two stepped wedge cluster randomised controlled trials during which existing weekend allied health services were to be temporarily removed with opportunity to contribute to a stakeholder-driven model of these services.Results: The main theme that emerged was a sense of unrealised potential amongst health professionals in terms of patient outcomes following hip and knee joint replacement surgery arising from tension between perceptions of actual versus ideal allied health practice. Assessing function and planning for discharge accordingly was perceived to be a higher priority than intervening to improve functional independence.Conclusion: Prioritising allied health intervention to low functioning and complex patients could be a more efficient use of allied health expertise in patients following lower limb replacement surgery than current practice in this setting that prioritises discharge.Implications for RehabilitationAllied health service delivery in the acute phase following hip and knee joint replacement needs to balance the needs of the health service with those of the patients.Prioritising allied health intervention to low functioning and complex patients could be a more efficient use of allied health expertise in this population than current practice, which is to prioritise discharge.There may be more scope for nurses to be involved in promoting early postoperative mobilisation following joint replacement surgery, especially in uncomplicated cases.

Joint replacement rehabilitation and the role of funding source.

OBJECTIVE: To examine associations between funding source, use of rehabilitation and outcomes after total joint replacement and to evaluate variations based on demographic characteristics. DESIGN: Cross-sectional, questionnaire-based national survey. SUBJECTS: Participants aged 45 years or older (n = 522) who received either private or public funding for their surgery, were recruited from the New Zealand Joint Registry 6 months after a total hip, total knee or unicompartmental knee replacement. RESULTS: The cohort was predominantly New Zealand European (90%), aged 68 years, with more men (55%) than women (45%). Privately funded participants were younger, had higher levels of education and employment, and lower rates of comorbidities at the time of surgery. Privately funded participants also reported spending less time on the surgical waiting list, were less likely to participate in pre-surgical rehabilitation, but reported more weeks of post-surgical rehabilitation and better patient-reported outcomes in terms of pain, function and quality of life, compared with their publicly funded counterparts. CONCLUSION: Factors already known to impact on joint replacement outcomes were associated with funding source in this cohort. Socio-economic differences and inequities between private and public systems exist consistent with limited available prior research. In this cross-sectional study, no clinically significant differences in outcomes between the groups were identified. Prospective research will help to clarify whether funding source directly affects joint replacement rehabilitation outcomes.

The paradox of self-rated health following joint replacement surgery.

PURPOSE: Self-rated health is a commonly used patient-reported outcome, but its responsiveness to is not well documented. We examined the ability of self-rated health to capture health changes attributable to a highly effective surgical intervention. METHODS: Prospective study of patients with severe osteoarthritis of the hip (N = 990) or knee (N = 907) who underwent total hip replacement (THA) or total knee replacement (TKA). Self-rated health was assessed pre-operatively and 1 year after surgery on a scale between "excellent" and "poor," along with other health items (other 11 items of the SF12 questionnaire) and multi-item Pain and Function scales. RESULTS: On average, self-rated health was unchanged by surgery. In both THA and TKA cohorts, of 10 patients, 6 rated their health the same after surgery as before, 2 gave a higher rating, and 2 gave a lower rating. In contrast, major improvements were observed for all other SF12 items, and for the Pain and Function scales, in both cohorts of patients. Nevertheless, both before and after surgery, self-rated health was associated with the other SF12 items and with Pain and Function scores. These associations were stronger after surgery than before. CONCLUSIONS: Self-rated health was not responsive to major improvements in health, documented by other instruments, attributable to joint replacement surgery. However, self-rated health was even more strongly associated with concurrent assessments of more specific health problems after surgery than before. Caution is advised in interpreting changes in self-rated health following health-altering interventions.

Managing Employees Undergoing Total Hip and Knee Replacement: Experiences of Workplace Representatives.

Introduction There is little research on return to work (RTW) from a workplace perspective following hip and knee replacement (THR/TKR) despite employers and other workplace personnel having a key role. Our aim was to explore the experiences of individuals in the workplace in managing employees undergoing THR/TKR. Methods Employers and other workplace representatives from a cross-section of employment sectors and sizes, with experience of managing employees undergoing THR/TKR in the previous 12 months, were recruited. Interviewees included small business owners, line managers, colleagues, human resources managers and occupational health advisers. Semi-structured, qualitative interviews were conducted and data were analysed thematically. Results Twenty-five individuals were interviewed. The main themes identified were accommodating the employee, and barriers and facilitators to RTW. Accommodations included changes to the work environment, amended duties, altered hours, changed roles and colleague support. Perceived barriers and facilitators to RTW included the role of GPs and occupational health, surgical issues, characteristics of the work environment and of employees. Conclusions Employers are motivated to effect supported RTW for employees undergoing THR/TKR but have insufficient guidance. Strategies are required to signpost employers to existing RTW advice, and to develop recommendations specific to lower limb arthroplasty. Communication between medical practitioners and employers should be facilitated in order to enhance the RTW experience of individuals undergoing THR/TKR.

Does Orthopaedic Outpatient Care Reduce Emergency Department Utilization After Total Joint Arthroplasty?

BACKGROUND: Emergency department (ED) visits after elective surgical procedures are a potential target for interventions to reduce healthcare costs. More than 1 million total joint arthroplasties (TJAs) are performed each year with postsurgical ED utilization estimated in the range of 10%. QUESTIONS/PURPOSES: We asked whether (1) outpatient orthopaedic care was associated with reduced ED utilization and (2) whether there were identifiable factors associated with ED utilization within the first 30 and 90 days after TJA. METHODS: An analysis of adult TRICARE beneficiaries who underwent TJA (2006-2014) was performed. TRICARE is the insurance program of the Department of Defense, covering > 9 million beneficiaries. ED use within 90 days of surgery was the primary outcome and postoperative outpatient orthopaedic care the primary explanatory variable. Patient demographics (age, sex, race, beneficiary category), clinical characteristics (length of hospital stay, prior comorbidities, complications), and environment of care were used as covariates. Logistic regression adjusted for all covariates was performed to determine factors associated with ED use. RESULTS: We found that orthopaedic outpatient care (odds ratio [OR], 0.73; 95% confidence interval [CI], 0.68-0.77) was associated with lower odds of ED use within 90 days. We also found that index hospital length of stay (OR, 1.07; 95% CI, 1.04-1.10), medical comorbidities (OR, 1.16; 95% CI, 1.08-1.24), and complications (OR, 2.47; 95% CI, 2.24-2.72) were associated with higher odds of ED use. CONCLUSIONS: When considering that at 90 days, only 3928 patients sustained a complication, a substantial number of ED visits (11,486 of 15,414 [75%]) after TJA may be avoidable. Enhancing access to appropriate outpatient care with improved discharge planning may reduce ED use after TJA. Further research should be directed toward unpacking the situations, outside of complications, that drive patients to access the ED and devise interventions that could mitigate such behavior. LEVEL OF EVIDENCE: Level III, therapeutic study.

Increasing Perioperative Communication With Automated Mobile Phone Messaging in Total Joint Arthroplasty.

BACKGROUND: Automated mobile phone messaging has not been reported in total joint arthroplasty (TJA). Our purpose was to compare Press Ganey (PG) and Hospital Consumer Assessment of Healthcare Providers and Systems (HCAHPS) scores between TJA patients who did and did not receive perioperative automated mobile phone messages. METHODS: Patients were prospectively enrolled and received messages for 1 week prior until 2 weeks after TJA. Message content included reminders, activity, and pain control. Patients answered select PG/HCAHPS and questions regarding their experience with the automated communication platform. Average PG/HCAHPS scores were compared to historical TJA patients in the 3-year window prior (control group) with significance P < .05. RESULTS: Thirty-seven consecutive patients were approached and 92% (n = 34) were enrolled. The experimental group was 47% male, with 80% patients between 51 and 75 years. The experimental (n = 30) and control groups (n = 26) were similar. Patients receiving messages were more likely to have a good understanding of health responsibilities (P = .024) and feel that the care team demonstrated shared decision-making (P = .024). Of patients enrolled, 87% felt messages helped them be more prepared for surgery, 100% felt messages kept them better informed, and 97% would participate again. CONCLUSION: TJA patients who received perioperative communication via automated mobile phone messaging had improved patient satisfaction scores postoperatively. Patients perceived this form of communication was useful and kept them better informed. Automated mobile phone messaging can be an easily integrated, helpful adjunct to surgeons, healthcare systems, and case managers to more effectively communicate with patients undergoing TJA in this era of value-based care.

Evaluating instrument responsiveness in joint function: The HOOS JR, the KOOS JR, and the PROMIS PF CAT.

12345Responsiveness is the ability to detect change over time and is an important aspect of measures used to detect treatment effects. The purpose of this study was to assess the responsiveness of the HOOS JR, the KOOS JR, and the PROMIS Physical Function (PF) computerized adaptive test (CAT) in a joint reconstruction practice. 983 patients were evaluated for joint conditions between 2014 and 2017 in an orthopaedic clinic and completed the three instruments at baseline and 3 and/or 6-month follow-up visits. Average age was 61.03 years (SD = 12.33, Range = 18-90 years) and the majority of the patients were White (n = 875, 89.0%). Three-month responsiveness was calculated two ways, as between 80 and 100 days and as 90 days and beyond. Six-month responsiveness was calculated as 170-190 days and as 180 days and beyond. All changes from baseline scores were significant at the 3-, >3-, and >6-month follow-up (p < 0.05). All three measures showed large effect sizes, ranging from 0.80-1.20 at each time-point. The standardized response mean was large for each measure and at each time-point (Range = 1.06-1.53). This study demonstrated the responsiveness of the HOOS JR, KOOS JR, and the PROMIS PF in adult reconstruction patients. The PROMIS PF was consistently the most responsive instrument in this analysis. CLINICAL SIGNIFICANCE: The HOOS JR, KOOS JR, and PROMIS PF are useful clinical instruments for assessing treatment change and may be selected as relevant to the specific needs and conditions of the adult joint reconstruction patient population. © 2017 Orthopaedic Research Society.

Action observation in the modification of postural sway and gait: Theory and use in rehabilitation.

The discovery of cortical neurons responsive to both the observation of another individual's movement and one's own physical movement has spurred scientists into utilising this interplay for rehabilitation. The idea that humans can quickly transfer motor programmes or refine existing motor strategies through observation has only recently gained interest in the context of gait rehabilitation but may offer significant promise as an adjunctive therapy to routine balance training. This review is the first dedicated to action observation in postural control or gait in healthy individuals and patients. The traditional use of action observation in rehabilitation is that the observer has to carefully watch pre-recorded or physically performed actions and thereafter imitate them. Using this approach, previous studies have shown improved gait after action observation in stroke, Parkinson's disease and knee or hip replacement patients. In healthy subjects, action observation reduced postural sway from externally induced balance perturbations. Despite this initial evidence, future studies should establish whether patients are instructed to observe the same movement to be trained (i.e., replicate the observed action(s)) or observe a motor error in order to produce postural countermeasures. The best mode of motor transfer from action observation is yet to be fully explored, and may involve observing live motor acts rather than viewing video clips. Given the ease with which action observation training can be applied in the home, it offers a promising, safe and economical approach as an adjunctive therapy to routine balance training.
