“…Prior literature has shown that comorbidities, whether assessed individually or by using validated indices [ 39 , 40 ], are associated with poor functional outcome after THR. In people with OA, comorbidities such as respiratory and cardiovascular disease have been linked with lower physical activity levels, compared to those without significant comorbidities [ 41 ] and current evidence demonstrates that activity levels do not improve after THR [ 42 , 43 ]. This suggests a role for increasing physical activity in patients with significant comorbidities prior to undergoing THR to maximise post-operative outcomes.…”

Background: Total hip replacement (THR) is a common and cost-effective procedure for end-stage osteoarthritis, but inappropriate utilization may be devaluing its true impact. The purpose of this study was to develop and test the internal validity of a prognostic algorithm for predicting the probability of non-response to THR surgery at 1 year. Methods: Analysis of outcome data extracted from an institutional registry of individuals (N = 2177) following elective THR performed between January 2012 and December 2019. OMERACT-OARSI responder criteria were applied to Western Ontario and McMaster Universities Arthritis Index (WOMAC) pain and function scores at pre- and 1 year post-THR, to determine non-response to surgery. Independent prognostic correlates of post-operative non-response observed in adjusted modelling were then used to develop a nomogram. Results: A total of 194 (8.9%) cases were deemed non-responders to THR. The degree of contribution (OR, 95% CI) of each explanatory factor to non-response on the nomogram was, morbid obesity (1.88, 1.16, 3.05), Kellgren–Lawrence grade <4 (1.89, 1.39, 2.56), WOMAC Global rating per 10 units (0.86, 0.79, 0.94) and the following co-morbidities: cerebrovascular disease (2.39, 1.33, 4.30), chronic pulmonary disease (1.64; 1.00, 2.71), connective tissue disease (1.99, 1.17, 3.39), diabetes (1.86, 1.26, 2.75) and liver disease (2.28, 0.99, 5.27). The concordance index for the nomogram was 0.70. Conclusion: We have developed a prognostic nomogram to calculate the probability of non-response to THR surgery. In doing so, we determined that both the probability of and predictive prognostic factors for non-response to THR differed from a previously developed nomogram for total knee replacement (TKR), confirming the benefit of designing decision support tools that are both condition and surgery site specific. Future external validation of the nomogram is required to confirm its generalisability.

Bioactive glass coatings can improve the osteo integration of metallic implants with the host tissue, thereby increasing their lifespan and overall success rate.However, complex composition-structure-property relations in phosphosilicatebased bioactive glasses make experimental determination of these relations and related composition design of bioactive coatings challenging. By applying molecular dynamics (MD)-based atomistic simulations with recently developed effective potentials, this work addresses the challenge by using a material genome approach to obtain the composition and structure effects on various key properties for bioactive coating applications. A series of potential bioactive glass compositions were studied and the composition effects on the mechanical and thermal properties that are critical to these bioactive glasses as a coating to metallic implants were calculated. Particularly, by varying the level of B 2 O 3 to SiO 2 substitutions, the effect of composition on various key properties was elucidated. It was found that by using cation in a 1 to 1 ratio (BO 3/2 to SiO 2 ) instead of the commonly used substitutions (B 2 O 3 to SiO 2 ), the composition effect can be more clearly expressed and, hence, recommended in future composition designs. Together with careful structural analysis, the origin of property changes can be elucidated. The atomistic computer simulation-based approach is, thus, an effective way to guide future bioactive glass designs for bioactive coatings and other applications.

Objective. The study aimed to explore patient perceptions of and motivations for physical activity after total knee joint replacement.Methods. Participants were purposively sampled after completing a public outpatient rehabilitation exercise group. Semistructured interviews were completed with 22 participants (mean age 70 years, 45% women) 6 to 12 months after total knee joint replacement. Interviews were audiotaped and transcribed verbatim. Themes were identified by an inductive and iterative process of data analysis.Results. The main theme to emerge was participants were in the dark about physical activity. Participants were typically not familiar with physical activity guidelines and had difficulty distinguishing between low-and moderateintensity physical activity. Three subthemes were identified: 1) people prioritize participation in meaningful life situations after total knee joint replacement, 2) rehabilitation was perceived to not explicitly address moderate-intensity physical activity levels, and 3) other health and social reasons replaced knee osteoarthritis as barriers to physical activity.Conclusion. Limited understanding of physical activity recommendations, prioritization of participation in meaningful life situations, rehabilitation that was impairment focused, and other health and social reasons appeared to contribute to low levels of moderate-intensity physical activity in adults after knee joint replacement. Addressing being in the dark about physical activity may be an important first step to increase the effectiveness of behavioral interventions designed to promote physical activity after total knee joint replacement.
