ABSTRACT
Background As a result of the corona pandemic, the implementation of physiotherapy as teletherapy was initially permitted for a limited period of time and subsequently approved for an unlimited period of time. Patients with gonarthrosis and coxarthrosis can be a target group.Aim To explore the behavior and feedback of patients with gonarthrosis and coxarthrosis, including patients who have had endoprosthetic treatment, during teletherapeutic treatments using screencasts.Method Patients with gonarthrosis or coxarthrosis, possibly after endoprosthetic treatment, received 6 treatment sessions including 5 by teletherapy. Participants completed the Musculoskeletal and Joint Health Questionnaire (MSK-HQ) and the Western Ontario and McMaster Universities Arthritis Index (WOMAC). The first and last treatment sessions were videotaped and thereafter transcribed. Coding of the text passages was deductively content-analytic.Results 5 patients were included (2 m, 3w;56 to 78 years;3 gonarthrosis, 2 coxarthrosis;of those 2 with endoprosthesis). The behavior and patients' perspectives were assigned to the main categories of person-related factors, treatment characteristics, point of view or environment-related factors, each with 2-5 subcategories. The evaluation showed a thoroughly positive attitude towards teletherapy. This despite initial doubts and lack of knowledge about the method. Factors such as framework conditions, technology, personal motivation and compliance, as well as the relationship between patient and therapist, were found to influence the patients' attitude towards this method. A mixed therapy design consisting of teletherapy and conventional methods received a preferred resonance. For all participants, a clinically relevant improvement of the WOMAC was observed (7-47 points;improvement MSK-HQ 1-13 points).Conclusion The behavior of the participants shows that a sound planned teletherapy can be well implemented in practice. The description of the patient perspective provides researchers and practitioners with information that can be used for the further development of teletherapeutic treatment concepts for patients with gonarthrosis or coxarthrosis as well as for patients with musculoskeletal complaints in general.
ABSTRACT
INTRODUCTION: To help combat the SARS-CoV-2 (COVID-19) pandemic, elective inpatient procedures have been reduced. The authors hypothesized that a nationwide lockdown would negatively affect the postoperative outcome after total knee arthroplasty (TKA) due to reduced physiotherapy as well as restrictions in external facilities of physiotherapy and rehabilitation. MATERIALS AND METHODS: We conducted a retrospective, comparative study including 41 patients who had undergone primary TKA during the first lockdown of the COVID-19 pandemic from March 2020 to April 2020 and a comparable control group consisting of 47 patients with a minimum follow-up of 6 months before the COVID-19 pandemic from 2019. Relevant end points were the visual analogue scale (VAS) for pain, Knee Society Function Score (KSS), Oxford Knee Score (OKS), Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), and range of motion (ROM). RESULTS: The lockdown group had a significantly worse outcome compared to the control group 6 months after TKA regarding WOMAC (p = 0.001), KSS (p < 0.001), OKS (p < 0.001), and length of hospital stay (p < 0.001). We found no statistically significant difference between the groups in ROM (p = 0.132), KSFS (p = 0.933), VAS at rest (p = 0.9.22), and exercise (p = 0.304). CONCLUSION: The COVID-19 pandemic negatively affected early clinical outcome parameters of elective primary TKA at 6 months of follow-up due to restrictions in postoperative care. We believe that standardized protocols for physiotherapy will improve clinical outcomes for TKA in the event of future lockdowns and underline the importance of appropriate postoperative care during this pandemic.
ABSTRACT
BACKGROUND: This study analyzed complication rates following primary elective total joint arthroplasty (TJA) in patients who subsequently contracted COVID-19. METHODS: A large national database was queried for adult patients who underwent primary elective TJA in 2020. Patients who contracted COVID-19 after total knee arthroplasty (TKA) or total hip arthroplasty (THA) underwent 1:6 matching (age [±6 years], sex, month of surgery, COVID-19-related comorbidities) to patients who did not. Differences between groups were assessed using univariate and multivariate analyses. Overall, 712 COVID-19 patients were matched to 4,272 controls (average time to diagnosis: 128-117 days [range, 0-351]). RESULTS: Of patients diagnosed <90 days postoperatively, 32.5%-33.6% required COVID-19-driven readmission. Discharge to a skilled nursing facility (adjusted odds ratio [aOR] 1.72, P = .003) or acute rehabilitation unit (aOR 4.93, P < .001) and Black race (aOR 2.28, P < .001) were associated with readmission after TKA. Similar results were associated with THA. COVID-19 patients were at increased risk of pulmonary embolism (aOR 4.09, P = .001) after TKA and also periprosthetic joint infection (aOR 4.65, P < .001) and sepsis (aOR 11.11, P < .001) after THA. The mortality rate was 3.51% in COVID-19 patients and 7.94% in readmitted COVID-19 patients compared to 0.09% in controls, representing a 38.7 OR and 91.8 OR of death, respectively. Similar results were observed for TKA and THA separately. CONCLUSION: Patients who contracted COVID-19 following TJA were at greater risk of numerous complications, including death. These patients represent a high-risk cohort who may require more aggressive medical interventions. Given the potential limitations presently, prospectively collected data may be warranted to validate these findings.
ABSTRACT
BACKGROUND: Exergames can provide encouraging exercise options. Currently, there is limited evidence regarding home-based exergaming in the postoperative phase of total knee replacement (TKR). OBJECTIVE: This study aimed to investigate the effects of a 4-month postoperative home-based exergame intervention with an 8-month follow-up on physical function and symptoms among older persons undergoing TKR compared with home exercise using a standard protocol. In addition, a concurrent embedded design of a mixed methods study was used by including a qualitative component within a quantitative study of exergame effects. METHODS: This was a dual-center, nonblinded, two-arm, parallel group randomized controlled trial with an embedded qualitative approach. This study aimed to recruit 100 patients who underwent their first unilateral TKR (aged 60-75 years). Participants were randomized to the exergame or standard home exercise arms. Participants followed a custom-made exergame program independently at their homes daily for 4 months. The primary outcomes at 4 months were function and pain related to the knee using the Oxford Knee Score questionnaire and mobility using the Timed Up and Go test. Other outcomes, in addition to physical function, symptoms, and disability, were game user experience, exercise adherence, physical activity, and satisfaction with the operated knee. Assessments were performed at the preoperative baseline and at 2, 4, and 12 months postoperatively. Exergame adherence was followed from game computers and using a structured diary. Self-reported standard exercise was followed for 4 months of intervention and physical activity was followed for 12 months using a structured diary. Qualitative data on patients' perspectives on rehabilitation and exergames were collected through laddering interviews at 4 and 12 months. RESULTS: This study was funded in 2018. Data collection began in 2019 and was completed in January 2022. The COVID-19 pandemic caused an unavoidable situation in the study for recruitment, data collection, and statistical analysis. As of November 2020, a total of 52 participants had been enrolled in the study. Primary results are expected to be published by the end of 2022. CONCLUSIONS: Our study provides new knowledge on the effects of postoperative exergame intervention among older patients with TKR. In addition, this study provides a new understanding of gamified postoperative rehabilitation, home exercise adherence, physical function, and physical activity among older adults undergoing TKR.

ABSTRACT
Objectives: To determine the budget impact if knee orthoses were funded for patients with severe osteoarthritis (OA) of the knee from a private Australian payer perspective. Method(s): The ISPOR Principles of Good Practice were used to guide a budget impact analysis comparing the use of knee orthoses to delay total knee reconstruction (TKR) versus the current environment. Delayed TKR was estimated based on a systematic review of electronic databases and a web-based search. Utilisation for TKR (sourced from Australian Medical Benefits Schedule statistics) was projected over the time horizon (2023 to 2027). The clinically eligible (i.e., target) population was based on the proportion of patients with OA of the knee in a large US cohort (N=8,002) deemed to have had TKR prematurely. The cost of TKR was based on Australian hospital separation data. Result(s): Funding of knee orthoses was associated with a cost-saving of $AUD122 to $AUD126 million over a 5-year time horizon based on device costs of $AUD500 and $AUD395, respectively. The cost-savings were primarily driven by 18,000 delayed TKR procedures. Knee orthosis, such as the Thuasne OA, were also associated with improvements in clinical outcomes including pain-free walk distance, pain during exercise, and lequesne index score (P<0.005). Conclusion(s): The widespread prevalence of COVID-19 has disrupted the capacity for Australian hospitals to undertake elective surgeries. The median wait-list time for TKR, which accounted for 47,000 surgeries in 2020-2021, increased from 223 to 308 days in Australia between 2019-2020 to 2020-2021. Our research indicates that the funding of appropriate knee orthoses in patients with severe OA has a cost-saving budget impact while offering potential clinical improvement for patients and reduced pressure on elective surgery wait lists.Copyright © 2022
ABSTRACT
BACKGROUND: There is limited data reviewing complication risks associated with total joint arthroplasty (TJA) after recovering from COVID-19. This study evaluated complications within 90 days of TJA in patients who had a COVID-19 diagnosis at varying intervals prior to surgery versus a non-COVID-19 cohort. METHODS: A large national database was used to identify patients diagnosed with COVID-19 in the six months prior to total hip arthroplasty (THA) or total knee arthroplasty. The incidence of complications within 90 days of surgery was recorded and compared to a COVID-19 negative control group matched 1:3 for age range in 5-year intervals, Charlson Comorbidity Index, and sex. There were 7,780 patients included in the study; 5,840 (75.1%) never diagnosed with COVID-19, 1,390 (17.9%) who had a COVID-19 diagnosis 0 to 3 months prior to surgery, and 550 (7.1%) who had a COVID-19 diagnosis 3 to 6 months prior to surgery. RESULTS: When compared to their COVID negative controls, patients who had a COVID-19 diagnosis 0 to 3 months prior to surgery had significantly higher rates of readmission (14.0 versus 11.1%, P = .001), pneumonia (2.2 versus 0.7%, P < .001), deep vein thrombosis (DVT) (3.3 versus 1.9%, P = .001), kidney failure (2.4 versus 1.4%, P = .006), and acute respiratory distress syndrome (1.4 versus 0.7%, P = .01). Patients who had a COVID-19 diagnosis 3 to 6 months prior to surgery had significantly higher rates of pneumonia (2.0 versus 0.7%, P = .002) and DVT (3.6 versus 1.9%, P = .005) when compared to their COVID negative controls. CONCLUSION: Patients diagnosed with COVID-19 within three months prior to TJA have an increased risk of 90-day postoperative complications. Risk for pneumonia and DVT remains elevated even when surgery was performed as far as 3 to 6 months after COVID-19 diagnosis.
ABSTRACT
Purpose: Osteoarthritis of the knee (knee OA) is the most prevalent form of OA, frequently leading to significant pain and an overall reduction in quality of life. The available options for managing pain, associated with knee OA, are well documented. They include various oral analgesic medications (for example, NASIDs and opioids), intraarticular agents, notably, hyaluronic acid and corticosteroids, and where pharmacological and lifestyle options have been exhausted, orthopedic surgery, including total knee replacement (TKR). The treatment option(s) a patient may receive, in which order and at what time point, post-diagnosis may vary significantly between healthcare centers. The current study focuses specifically on knee OA in Germany, aiming to determine the epidemiology, patient characteristics and treatment schemes for the management of pain associated with knee OA. Method(s): A non-interventional, retrospective health claims data analysis was performed with an anonymized, age- and sex-representative sample of the Institute for Applied Health Research Berlin GmbH (InGef) database. The database that was used for this study includes approximately 4.8 million persons from approx. 60 statutory health insurances (SHI). Patients >=18 years of age were analyzed cross-sectionally for each year 2015-2020. Using ICD-10 and ATC codes, newly diagnosed patients in 2015 were also analyzed longitudinally until end of 2020. Result(s): The average period prevalence of knee OA was 7.34%, with a slight increase during the years 2015-2020. Incidence ranged from 1.71% of patients in 2015 to 1.46% of patients in 2020. Females and patients aged >=66 years had both a higher prevalence and incidence proportion compared to males and younger persons. Approximately 62% of newly diagnosed patients in 2015 received medical treatment during follow-up, most of whom were prescribed non-opioid analgesics;WHO I category (96.84%), followed by WHO II (2.45%) and WHO III (0.71%), as first line treatment. This analysis could not account for the use of any over the counter medications, or medicines prescribed in hospital, prior to, or after diagnosis. As many as 16.58% of newly diagnosed patients had surgery within 5 years. Knee replacement was the most common type of surgery with rising prevalence. The number of patients in whom surgery was performed decreased slightly from 5,38% to 4,03% during the study years considered (Figure 1);the decrease in 2020 may, in-part, be a reflection of the COVID-19 pandemic and the knock-on impact on healthcare systems. Of the 8,318 surgical patients, 2,101 patients (25.26%) had no record of having received any prescription pharmacological treatment prior to first surgery. The median time from first diagnosis until surgery in newly diagnosed patients was 346 days for any surgery, and 564 days for knee replacement. [Formula presented] Conclusion(s): With a stable incidence and a growing population, the number of patients with knee OA in Germany is slowly rising. In parallel, there is an slight decrease in total knee surgeries occurring each year with an increasing proportion of TKRs. Time until first surgery, in general, and TKR in newly diagnosed patients is relatively short, compared to other countries, with some patients having no record of having received any prescription medication prior to first surgery. Other treatment options such as opioids and intraarticular agents, appear to play a relatively minor role, in newly diagnosed patients, in current practice in Germany.Copyright © 2023
ABSTRACT
Purpose: Knee distraction (KD) treatment for young (<65) patients with end-stage knee osteoarthritis (OA) has previously been shown to successfully postpone a knee arthroplasty for years by reducing pain, improving function, and inducing joint tissue repair. During KD treatment, the tibia and femur are separated ~5 mm for ~6 weeks using an external fixation device. The studies performed thus far have used proof-of-concept medical devices intended for other applications than KD. Recently, the first device specifically designed and intended for KD treatment has been developed. The purpose of the current study was to evaluate the clinical efficacy of this intended device. Method(s): In 5 hospitals, 65 patients with end-stage knee OA, in general practice considered for arthroplasty or high tibial osteotomy, were offered KD treatment by their orthopedic surgeon. Inclusion criteria were judged by the orthopedic surgeon and included age <=65 years, BMI <35 kg/m2 with weight <=110 kg, sufficient knee stability and physical condition, KL grade >=2, malalignment <=10 degrees, no history of inflammatory or septic arthritis. KD was performed according to a standardized protocol. Before and 1 and 2 years after treatment, standardized knee radiographs were performed and patients filled out WOMAC (for pain and function, 0-100, primary clinical outcome) and SF-36 (for quality of life, 0-100, secondary outcome) questionnaires. From the radiographs, minimum joint space width (JSW, mm, primary structural outcome) was measured by one experienced observer and KL grade at baseline was determined. Use of self-reported pain medication (paracetamol, opioids, NSAIDs) and intra-articular injections were registered as well, as were adverse events. Changes over 2 years were evaluated for statistical significance with paired t-tests for continuous variables and McNemar's tests for categorical variables. For the primary clinical outcome (WOMAC), clinical significance was evaluated as well, on group level defined as an increase of >=15 points and on individual level using OARSI-OMERACT response criteria. The influence of adverse effects on 2-year changes in primary outcomes was analyzed with independent t-tests. Result(s): Of the 65 treated patients (age: 53.3+/-6.7;BMI: 28.0+/-3.2;sex: 38 (55%) male;KL grade 0/1/2/3/4: 0 (0%) / 7 (11%) / 26 (40%) / 23 (36%) / 9 (14%)), 50 patients completed 2 years follow-up: 6 patients received partial or total arthroplasty (of which 3 in the 1st year) and 8 patients were lost to follow-up in the 2nd year (primarily due to COVID restrictions). The total WOMAC score (Figure 1A/B) showed a statistically and clinically significant improvement over 1 (+28.4 points;p<0.001) and 2 (+26.2 points;p<0.001) years, as did all the subscales (all p<0.001). After 1 year 72% of patients were OARSI-OMERACT responders, while after 2 years this was 51%. The minimum JSW (Figure 1C/D) significantly improved over 1 (+0.5 mm;p<0.001) and 2 (+0.4 mm;p=0.015) years as well. The physical component scale of the SF36 (Figure 2A/B) showed statistically significant improvement over 1 (+10.5 points;p<0.001) and 2 (+9.8;p<0.001) years, while the mental component scale (Figure 2C/D) did not (both p>0.26). The most common adverse event (Table 1) was pin tract skin infections, experienced by 46 (71%) of patients. In most cases (36;78% of cases) they could be treated with oral antibiotics, while in 3 of the cases (5% of treated patients) hospitalization and/or intravenous antibiotics were needed. Also, 8 (12%) of patients experienced device related complications. Experiencing pin tract infections or device complications did not significantly influence 2-year changes in primary outcomes in these patients (both p>0.05). Before treatment, 39 (60%) of patients used pain medication (Table 2), most often paracetamol (20;31%) or NSAIDs (16;25%). Around half used them daily. After treatment, significantly less patients used pain medication (p<0.001), with 35% at 1 year and 36% at 2 years. In total 12 (18%) patients had received an intra-arti ular injection before KD treatment, of whom 5 (8%) steroids and 3 (5%) hyaluronic acid. Both in the 1st and 2nd year after treatment, 1 patient (2%) received an injection. Conclusion(s): Patients treated with the first device intended for KD treatment showed significant clinical and structural improvement after 1 and 2 years. Importantly, the effect was clinically relevant, as a majority of patients were clinical responders and pain medication use decreased. Long-term evaluation will show whether arthroplasty can be postponed successfully as well. [Formula presented] [Formula presented] [Formula presented] [Formula presented]Copyright © 2023
ABSTRACT
PURPOSE: Modern multimodal analgesia has been shown to significantly reduce opioid use following total knee arthroplasty (TKA). This study was conducted to determine if changing TKA discharge opioid prescriptions from automatic to upon request resulted in more opioid free recoveries without compromising pain control. METHODS: Between December 2019 and August 2021, an orthopedic surgeon performed 144 primary unilateral TKAs; patients received the same multimodal analgesia protocol except for postoperative opioid prescribing. The first consecutively-treated cohort automatically received an opioid prescription following discharge (automatic group) and the second cohort received opioid prescriptions only upon request (upon request group). Opioid prescription data were derived from a prescription monitoring program and patient-reported outcomes (PROs) were collected preoperatively and at 2 and 12 weeks postoperatively. RESULTS: A higher percentage of the upon request group was opioid free 3 months after TKA compared with the automatic group (55.6% vs 4.3%, p < 0.0001) without compromising pain or function. Among opioid-naïve patients, 72% in the upon request group were opioid free after TKA compared with 5.4% in the automatic group. Opioid prescribing was not significantly reduced among opioid-experienced patients regardless of the pain protocol. CONCLUSION: Requiring patients to request opioid prescriptions following TKA resulted in a higher rate of opioid free TKA, especially among opioid-naïve patients, without increasing pain compared with offering all patients an initial opioid prescription. LEVEL OF EVIDENCE: Level III.
ABSTRACT
OBJECTIVE: To explore changes in the epidemiological and clinical characteristics of patients who underwent knee arthroplasty (KA) over a 10-year period in China. METHODS: Medical records of patients with knee osteoarthritis (KOA), who underwent primary unilateral KA in 5 level I center hospitals in China between January 2011 and December 2020, were retrospectively reviewed and analyzed. To more clearly define changes over the years, patients were divided into two groups according to time of admission at 5-year intervals. Age, sex, body mass index (BMI), Kellgren-Lawrence (K-L) classification, comorbid diseases, surgical procedures, hospital stay, and hospitalization costs were compared between the two groups. RESULTS: A total of 23,610 patients with KOA (5400 male and 18,210 females; mean age: 65.7 ± 7.6 years) who underwent primary unilateral KA were included. The number of KAs increased in recent years (group A, n = 7606 vs. group B, n = 16,004). Significant differences were noted in age, sex, BMI, K-L classification, comorbidities, surgical procedures, hospital stay, and hospitalization costs between the two periods (P < 0.05). More than three-quarters of KA cases involved females, and the age at surgery tended to be younger than that reported in foreign countries. In group B, the proportion of overweight and grade III, number of comorbidities, and unicompartmental knee arthroplasty patients increased compared to that in group A; however, hospitalization costs and length of hospital stay decreased. CONCLUSIONS: Results suggested that the epidemiological characteristics of patients undergoing KA have changed over time. An analysis of the epidemiological characteristics of patients undergoing KA treatment may provide a scientific basis for the prevention and control of KOA.

BACKGROUND: The COVID-19 virus is believed to increase the risk of diffusing intravascular coagulation. Total joint arthroplasty (TJA) is one of the most common elective surgeries and is also associated with a temporarily increased risk of venous thromboembolism (VTE). However, the influence of a history of COVID-19 infection on perioperative outcomes following TJA remains unknown. Therefore, this study sought to determine what effect a history of COVID-19 infection had on outcomes following primary TJA. METHODS: A retrospective case-control study using the national database was performed to identify all patients who had a history of COVID-19 and had undergone TJA, between 2019 and 2020. Patients who had a history of both were 1:1 matched to those who did not have a history of COVID-19, and 90-day outcomes were compared. A total of 661 TKA and 635 THA patients who had a history of COVID-19 were 1:1 matched to controls. There were no differences in demographics and comorbidities between the propensity-matched pairs in both TKAs and THAs studied. Previous COVID-19 diagnosis was noted in 28.3% of patients 5 days within TJA and in 78.6%, 90 days before TJA. RESULTS: Patients who had a previous diagnosis of COVID-19 had a higher risk of pneumonia during the postoperative period for both THA and TKA (6.9% versus 3.5%, P < .001 and 2.27% versus 1.21%, P = .04, respectively). Mean lengths of stay were also greater for those with a previous COVID-19 infection in both cohorts (TKA: 3.12 versus 2.57, P = .027, THA: 4.52 versus 3.62, P < .001). Other postoperative outcomes were similar between the 2 groups. CONCLUSION: COVID-19 infection history does not appear to increase the risk of VTE following primary TJA, but appears to increase the risk of pneumonia in addition to lengths of stay postoperatively. Individual risk factors should be discussed with patients, to set reasonable expectations regarding perioperative outcomes.
ABSTRACT
Background: The coronavirus disease 2019 (COVID-19) pandemic caused major transitions in total joint arthroplasty (TJA), notably with the increased utilization of same-day discharge (SDD) pathways. This study assessed the effect of accelerated discharge pathways following the resumption of elective cases during the COVID-19 pandemic on SDD rates, adverse events, and characteristics associated with successful SDD following total hip and total knee arthroplasty. Methods: This retrospective study split patients into cohorts: TJA prior to COVID-19 (pre-COVID, July 2019-December 2019) and TJA following the resumption of elective surgeries (post-COVID, July 2020-December 2020). Patient characteristics such as age, sex, body mass index, American Society of Anesthesiologists score, and pertinent comorbidities were analyzed, and length of stay, 30-day emergency department (ED) visit rates, readmissions, and reoperations were compared. Results: A total of 1333 patients met inclusion criteria that were divided into pre-COVID (692) and post-COVID (641) cohorts. The pre-COVID group had a median age of 69 years (interquartile range 63-76), and the post-COVID group had a median age of 68 years (interquartile range 61-75) (P = .024). SDD increased from 0.1% to 28.9% (P < .001), and length of stay decreased from 1.3 days to 0.89 days (P < .001). There was no change in 30-day ED visits, readmissions, or reoperations (P = .817, P = .470, and P = .643, respectively). There was no difference in ED visits, readmissions, or reoperations in SDD patients. The odds of SDD were associated with age (P < .001, odds ratio [OR] = 0.94), body mass index (P = .006, OR = 0.95), male sex (P < .001, OR = 1.83), and history of tobacco use (P < .001, OR = 1.87). Conclusions: At our institution, the COVID-19 pandemic accelerated the utilization of SDD pathways without increasing ED visits, readmissions, or reoperations.

ABSTRACT
AIMS: This study aimed to investigate the estimated change in primary and revision arthroplasty rate in the Netherlands and Denmark for hips, knees, and shoulders during the COVID-19 pandemic in 2020 (COVID-period). Additional points of focus included the comparison of patient characteristics and hospital type (2019 vs COVID-period), and the estimated loss of quality-adjusted life years (QALYs) and impact on waiting lists. METHODS: All hip, knee, and shoulder arthroplasties (2014 to 2020) from the Dutch Arthroplasty Register, and hip and knee arthroplasties from the Danish Hip and Knee Arthroplasty Registries, were included. The expected number of arthroplasties per month in 2020 was estimated using Poisson regression, taking into account changes in age and sex distribution of the general Dutch/Danish population over time, calculating observed/expected (O/E) ratios. Country-specific proportions of patient characteristics and hospital type were calculated per indication category (osteoarthritis/other elective/acute). Waiting list outcomes including QALYs were estimated by modelling virtual waiting lists including 0%, 5% and 10% extra capacity. RESULTS: During COVID-period, fewer arthroplasties were performed than expected (Netherlands: 20%; Denmark: 5%), with the lowest O/E in April. In the Netherlands, more acute indications were prioritized, resulting in more American Society of Anesthesiologists grade III to IV patients receiving surgery. In both countries, no other patient prioritization was present. Relatively more arthroplasties were performed in private hospitals. There were no clinically relevant differences in revision arthroplasties between pre-COVID and COVID-period. Estimated total health loss depending on extra capacity ranged from: 19,800 to 29,400 QALYs (Netherlands): 1,700 to 2,400 QALYs (Denmark). With no extra capacity it will take > 30 years to deplete the waiting lists. CONCLUSION: The COVID-19 pandemic had an enormous negative effect on arthroplasty rates, but more in the Netherlands than Denmark. In the Netherlands, hip and shoulder patients with acute indications were prioritized. Private hospitals filled in part of the capacity gap. QALY loss due to postponed arthroplasty surgeries is considerable.Cite this article: Bone Jt Open 2022;3(12):977-990.
ABSTRACT
INTRODUCTION: The coronavirus disease 2019 (COVID-19) pandemic strained the United States healthcare system, and associated policies resulted in the postponement or cancellation of many elective surgeries. While most orthopaedic surgeons are aware of how the pandemic affected their patients' care, broader national trends in the operative treatment of orthopaedic knee pathology are poorly characterized. Therefore, the purpose of this study was to identify trends in orthopaedic knee procedures during the COVID-19 pandemic. METHODS: The TriNetX database was queried for orthopaedic knee procedures performed from March 2018 to May 2021. Procedures were classified as arthroplasty (total knee arthroplasty (TKA), revision total knee arthroplasty) or non-arthroplasty (tendon or ligament repair, fracture fixation). Procedural volume per healthcare organization was determined over five seasons from March 2020 to May 2021 and compared to overlapping pre-pandemic periods from March 2018 to May 2019. Descriptive analysis was performed, and comparisons were made using a Student's T-test. RESULTS: Compared to the pre-pandemic period, there were significant decreases in primary TKA (p=0.016), femoral or entire tibial component revision TKA (p=0.005), and open treatment of femoral shaft fractures (p=0.007) in spring 2020. Procedural volume returned to baseline in summer 2020 through winter 2021. In spring 2021, primary TKA (p=0.017) and one component revision TKA (p=0.003) increased compared to the pre-pandemic period. CONCLUSION: The greatest decrease in knee procedures occurred early in the pandemic. Rates of these procedures have since rebounded, with some exceeding pre-pandemic levels. Hospitals are now better able to accommodate orthopaedic surgical volume while continuing to care for patients with COVID-19.
ABSTRACT
A range of extended reality technology integration, including immersive virtual reality (IVR), augmented reality (AR), as well as mixed reality, has lately acquired favour in orthopaedics. The utilization of extended reality machinery in knee arthroplasty is examined in this review study. Virtual reality (VR) and AR are usually exercised together in orthopaedic surgical training as alluring training outside of the operation theatre is acknowledged as a good surgical training tool. The use of this technology, its consequences for orthopaedic surgeons and their patients, and its moral and practical issues are also covered. Head-mounted displays (HMDs) are a potential addition directed toward improving surgical precision along with instruction. Although the hardware is cutting-edge, substantial effort needs to be done to develop software that enables seamless, trustworthy integration into clinical practice and training. Remote virtual rehabilitation has drawn increasing attention in recent years, and its significance has increased in light of the recent outbreak of the COVID-19 epidemic. Numerous medical sectors have shown the benefits of telerehabilitation, gamification, VR, and AR. Given the rising demand for orthopaedic therapy and its rising costs, this is a requirement. A remote surgeon can impart knowledge without being present, by virtually placing his or her hands in the visual field of a local surgeon using AR technology. With the use of this innovation, orthopaedic surgery seems to have been able to participate in the telemedicine revolution. This technology may also have an impact on how surgeons collaborate and train for orthopaedic residencies in the future. Volatility in the HMD market will probably stall improvements in surgical education.

SESSION TITLE: Drug-Induced Lung Injury Pathology Case Posters SESSION TYPE: Case Report Posters PRESENTED ON: 10/19/2022 12:45 pm - 01:45 pm INTRODUCTION: Acute eosinophilic pneumonia (AEP) is an atypical cause of acute hypoxic respiratory failure in adults, however if not identified can prove to be fatal. It can all be a COVID19 mimic during the pandemic. AEP has several causes, such as inhalational drugs, infections and various pharmaceuticals. Often, patients will have an acute respiratory syndrome for less than one-month, pulmonary infiltrates on chest computed tomography (CT) or radiography (CXR), in addition to bronchoalveolar lavage (BAL) with more than 25% of eosinophils. CASE PRESENTATION: A 79 y/o man underwent an elective total knee replacement complicated by acute lower limb ischemia from an occluded bypass graft. He developed methicillin-resistant Staphylococcus aureus (MRSA) and Vancomycin-resistant Enterococcus (VRE) joint and soft tissue infection of the lower extremity. He was prescribed a 6-week course of Daptomycin. He presented about 3 weeks into treatment with shortness of breath. He was initially diagnosed with acute on chronic congestive heart failure (CHF) exacerbation and COVID negative. He was initially treated with diuretics. He developed acute renal failure requiring dialysis and acute hypoxic respiratory failure requiring intubation. CXR revealed bilateral lung infiltrates with BAL having 80% eosinophils, eosinophilia and urinalysis positive for eosinophils. Daptomycin was discontinued and he was started on systemic steroids for a two-week course. He was successfully extubated 5 days after diagnosis of AEP and was subsequently discharged to a rehabilitation facility on lifelong Doxycycline for MRSA prosthetic joint infection prophylaxis. DISCUSSION: AEP related to Daptomycin was first reported in 2007, in a patient that developed the condition after receiving treatment for endocarditis. Daptomycin caused an inflammatory reaction within the lungs, due to an accumulation of the drug within the pulmonary surfactant. Our case report patient met all components for AEP diagnosis, in addition to symptom onset being approximately 3 weeks into treatment. The ultimate treatment for AEP is to stop the reversible cause, if identifiable, along with glucocorticoids and symptomatic support. Prognosis for patients with AEP is excellent when diagnosis is prompt, and usually infiltrates are resolved within 1 month without long term adverse pulmonary effects. Our patient was discharged to an acute rehab facility without supplemental oxygen therapy and continues to improve from functional standpoint. This case a definite cause of AEP from Daptomycin presented as COVID19 pneumonia mimic. It highlights the importance of rapid diagnosis to prevent morbidity and mortality. CONCLUSIONS: The differential in a patient with acute hypoxic respiratory failure is numerous, especially during the COVID19 pandemic. During these challenging times, it is important to think of atypical causes, such as AEP to improve the patient's clinical status. Reference #1: Allen JN, Pacht ER, Gadek JE, Davis WB.

ABSTRACT
To meet the future demand for physiotherapy in the face of a growing number of patients after arthroplasty, health service providers need a solution for the provision of appropriate therapy. One potential option could be teletherapy, which is becoming increasingly important due to the pandemic situation surrounding SARS-COV-2. Remote options can enable therapy for people who cannot visit a practice for different reasons. They also have the potential to realize cost savings. This review aimed to clarify whether remote physiotherapy in patients after knee arthroplasty was comparable to conventional physiotherapy. A literature review, carried out across the Cochrane, Europe PMC and PubMed databases for the period from January 1 to May 4, 2021, identified 4 suitable RCTs. All of the 4 RCTs demonstrated that remote therapy has a positive impact on function in patients after total arthroplasty of the knee and is not inferior to conventional physiotherapy. Results were clinically significant. Accordingly, teletherapy can be considered as an alternative. However, some of the trials were viewed critically due to methodological weaknesses. Consequently, this review cannot give a definite recommendation. Further studies are required to get clear results and issue a strong clinical recommendation for patients after total knee arthroplasty.
ABSTRACT
PURPOSE: In response to COVID-19, elective surgeries including unicompartmental knee arthroplasties (UKA) decreased. We aimed to quantify and compare temporal trends in utilization and complications in the calendar year 2019 (pre-pandemic) to 2020 in the USA. METHODS: The 2019 to 2020 ACS-NSQIP database was queried for patients undergoing elective UKA. Patients prior to COVID-19 (2019 and 2020 Q1) were compared to those after (2020 Q2-Q4). Case volumes, patient demographics, complications, and lengths of stay (LOS) were compared between years. Pearson's chi-square test was used to compare patient demographics. Linear regression was conducted to evaluate the change in case volumes. P values less than 0.05 were significant. RESULTS: In total, 3361 patients underwent UKA: 1880 in 2019 and 1481 in 2020. The number of outpatient UKAs increased (56.4% vs. 65.6%; p < 0.001). There was no significant difference in the volume of cases in 2019Q1 through 2020Q1 (p = 0.424). Case volumes fell by 60% in 2020Q2 compared with the average quarterly volume in 2019. Comparing 2019 to 2020, there was no significant difference in rates of total complications (2.1% vs. 2.2%; p = 0.843), minor complications (1.2% vs. 0.9%; p = 0.529), major complications (1.1% vs. 1.4%; p = 0.447), infection complications (1.0% vs. 0.8%; p = 0.652), wound complications (0.1% vs. 0.1%; p = 1.0), cardiac complications (0.0% vs. 0.1%; p = 0.111), pulmonary complications (0.1% vs. 0.2%; p = 0.473), hematology complications (0.1% vs. 0.1%; p = 1.0), renal complications (0.1% vs. 0.0%; p = 1.0), and Clavien-Dindo IV complications (0.1% vs. 0.4%; p = 0.177). CONCLUSION: UKA case volumes declined during the second quarter of 2020. A significant proportion of surgeries were transitioned outpatient, despite no change in complication rates.
