[Impact of the COVID-19 Pandemic on Health-Related Quality of Life in Older Adults With Preoperative Knee Osteoarthritis].

BACKGROUND: Knee osteoarthritis is prevalent in older adults worldwide. Quality of life was negatively affected by the COVID-19 pandemic. PURPOSE: This study was designed to examine osteoarthritis severity and health-related quality of life (QOL) in older adults with knee osteoarthritis before total knee replacement during the COVID-19 pandemic and to identify the related predictors of QOL. METHODS: This cross-sectional correlation study involved convenience sampling in the orthopedic ward of a regional teaching hospital in central Taiwan from June 2020 to June 2021 using the Western Ontario and McMaster Universities Arthritis Index and the SF-36v2 Health Survey. The data were analyzed using Pearson's correlation coefficient analysis, independent samples t test, and one-way analysis of variance to determine correlations among demographic variables, osteoarthritis severity, and QOL. The predictors of QOL were examined using stepwise multiple linear regression analysis. RESULTS: A total of 60 older adults diagnosed with knee osteoarthritis were sampled. The average age was 70 years and the average osteoarthritis severity score was 70.45. Being male, having comorbidities, and having a relatively high level of monthly disposable income were associated with poorer QOL. Moreover, more severe knee pain, stiffness, and physical dysfunction were associated with better psychological QOL. CONCLUSIONS / IMPLICATIONS FOR PRACTICE: During the COVID-19 pandemic, the severity of knee osteoarthritis affects preoperative quality of life in older adults. Clinicians should detect signs of pain and physical dysfunction in these patients in advance and intervene in a timely manner to improve their QOL before surgery.

Changes in epidemiological characteristics of knee arthroplasty in eastern, northern and central China between 2011 and 2020.

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.

Changes to consultations and diagnosis of osteoarthritis in primary care during the COVID-19 pandemic.

OBJECTIVE: General practitioners (GP) are often the first medical professionals to treat musculoskeletal complaints. Yet the impact of COVID-19 on primary care utilisation for musculoskeletal complaints is largely unknown. This study quantifies the impact of the pandemic on primary care utilisation for musculoskeletal complaints and specifically osteoarthritis (OA) in the Netherlands. DESIGN: We extracted data on GP consultations in 2015-2020 from 118,756 patients over 45 years of age and estimated reductions in consultations in 2020 as compared to 5-year average. Outcomes were GP consultations for: any musculoskeletal complaints, knee and hip OA, knee and hip complaints, and newly diagnosed knee and hip OA/complaints. RESULTS: The relative reductions in consultations ranged from 46.7% (95% confidence intervals (CI): 43.9-49.3%) (all musculoskeletal consultations) to 61.6% (95% CI: 44.7-73.3%) (hip complaints) at the peak of the first wave, and from 9.3% (95% CI: 5.7-12.7%) (all musculoskeletal consultations) to 26.6% (95% CI: 11.5-39.1%) (knee OA) at the peak of the second wave. The reductions for new diagnoses were 87.0% (95% CI: 71.5-94.1%) for knee OA/complaints, and 70.5% (95% CI: 37.7-86.0%) for hip OA/complaints at the peak of the first wave, and not statistically significant at the peak of the second wave. CONCLUSION: We observed 47% reduction in GP consultations for musculoskeletal disorders during the first wave and 9% during the second wave. For hip and knee OA/complaints, the reductions were over 50% during the first, and 10% during the second wave. This disruption may lead to accumulation of patients with severe OA symptoms and more requests for arthroplasty surgery.

Referrals for physical therapy for osteoarthritis during the COVID-19 pandemic: A retrospective analysis.

BACKGROUND: Osteoarthritis (OA) is a leading cause of musculoskeletal pain and disability among Americans. Physical therapy (PT) is recommended per the 2019 ACR /Arthritis Foundation Guideline for Treatment of OA of the Hand, Hip, and Knee. During COVID-19, access to healthcare has been altered in a variety of clinical settings, with the pandemic creating delays in healthcare, with an unknown impact on access to PT care for OA. OBJECTIVES: We sought to determine whether referrals to PT for OA were reduced in 2020 during the COVID-19 pandemic compared to 2019. METHODS: A retrospective analysis was done of 3586 PT referrals placed by the University of California, Davis for 206 OA ICD-10 codes from January to November 2019 and from January to November 2020. The numbers of PT referrals per month of each year were compared using both descriptive statistics and Poisson Regression analysis. RESULTS: A total of 1972 PT referrals for OA were placed from January to November 2019. Only 1614 referrals for OA were placed from January to November 2020, representing a significant decrease (p = 0.001). Month-by-month analysis of 2020 compared to 2019 revealed statistically significant drops in PT referrals for OA in April (p = 0.001), May (p = 0.001), and August (p = 0.001). CONCLUSIONS: These findings reveal a significant reduction in the number of referrals for PT for OA placed in 2020 during the first year of the COVID-19 pandemic. These reductions were particularly evident in the months following state-mandated actions and closures. Factors associated with this outcome may include decreased access to primary care providers, perceptions of PT availability by health care providers, decreased mobility limiting access to both clinic and PT appointments, and/or willingness to engage in PT by patients during the pandemic.

Experience of the COVID-19 pandemic as lived by patients with hip and knee osteoarthritis: an Italian qualitative study.

OBJECTIVE: To examine the experience of the COVID-19 pandemic as lived by people with hip and knee osteoarthritis (OA), in Italy. DESIGN: A qualitative study based on semi-structured interviews. SETTING: Urban and suburban areas in northern Italy. PARTICIPANTS: A total of 11 people with OA were enrolled through a purposeful sampling and completed the study. PRIMARY OUTCOME MEASURE: The experience of Italian people with OA during the COVID-19 pandemic. RESULTS: Four themes were brought to the forefront from the analysis of the interviews. (1) Being Stressed for the Limited Social Interactions and for the Family Members at High Risk of Infection, as the interviewees were frustrated because they could not see their loved ones or felt a sense of apprehension for their relatives. (2) Recurring Strategies to Cope with the Pandemic such as an active acceptance towards the situation. (3) Being Limited in the Possibility of Undergoing OA Complementary Treatments and Other Routine Medical Visits. (4) Being Unaware of the Importance of Physical Activity as First-Line Interventions which was an attitude already present before the pandemic. CONCLUSION: The COVID-19 pandemic and related restrictions impacted the quality of life and the care of individuals with hip and knee OA. The social sphere seemed to be the most hindered. However, the interviewees developed a good level of acceptance to deal with the pandemic. When it came to their care, they faced a delay of routine medical visits not related to OA and of other complementary treatments (eg, physical therapies) to manage OA. Finally, a controversial result that emerged from these interviews was that first-line interventions for OA (ie, therapeutic exercise) was not sought by the interviewees, regardless of the restrictions dictated by the pandemic. Policy-making strategies are thus necessary to support the awareness of the importance of such interventions.

Clinical prioritisation of revision knee surgical procedures: BASK working group consensus document.

BACKGROUND: Elective orthopaedic surgery during the Covid-19 pandemic requires careful case prioritisation. We aimed to produce consensus-based guidelines on the prioritisation of revision total knee arthroplasty (TKA) procedures. METHOD: Twenty-three revision TKA scenarios were assigned priority (NHS England/Royal College of Surgeons scale) by the British Association for Surgery of the Knee (BASK) Revision Knee Working Group (n = 24). Consensus agreement was defined as ≥70% respondents (18/24) giving the same prioritisation. Two voting rounds were undertaken; procedures achieving <70% agreement were given their most commonly assigned priority. RESULTS: 18/23 procedures achieved ≥70% agreement. Three were P1a (surgery within <24 h); DAIR for sepsis, peri-prosthetic fracture (PPF) fixation and PPF-revision TKA. Three were P1b (<72 h); debridement, antibiotics and implant retention (DAIR) for a stable patient, flap coverage for an open knee, and acute extensor mechanism rupture. Eight were P2 (<4 weeks), including aseptic loosening at risk of collapse, inter-stage patients with poor functioning spacers. Five were P3 (<3 months), including second stage revision for infection, revision for instability with limited mobility. Four were P4 (can wait >3 months) e.g. aseptic loosening. CONCLUSION: Sepsis and PPF surgery are the most urgent procedures. Although most procedures should be undertaken within one to three months (P2/3), these cases represent a small revision practice volume; P4 cases (e.g. aseptic loosening without risk of collapse) make up most surgeons' caseload. These recommendations are a guideline; patient co-morbidities, Covid-19 pathways, availability of support services and multi-disciplinary team discussion within the regional revision network will dictate prioritisation.
