RESUMEN
BACKGROUND: Postoperative morbidity in patients undergoing curative colorectal cancer surgery is high. Prehabilitation has been suggested to reduce postoperative morbidity, however its effectiveness is still lacking. OBJECTIVE: The aim of this study was to investigate the effectiveness of prehabilitation in reducing postoperative morbidity and length of hospital stay in patients undergoing colorectal cancer surgery. METHODS: A comprehensive electronic search was conducted in the CINAHL, Cochrane Library, Medline, PsychINFO, AMED, and Embase databases from inception to April 2023. Randomised controlled trials testing the effectiveness of prehabilitation, including exercise, nutrition, and/or psychological interventions, compared with usual care in patients undergoing colorectal cancer surgery were included. Two independent review authors extracted relevant information and assessed the risk of bias. Random-effect meta-analyses were used to pool outcomes, and the quality of evidence was assessed using Grading of Recommendations, Assessment, Development, and Evaluations (GRADE) guidelines. RESULTS: A total of 23 trials were identified (N = 2475 patients), including multimodal (3 trials), exercise (3 trials), nutrition (16 trials), and psychological (1 trial) prehabilitation. There was moderate-quality evidence that preoperative nutrition significantly reduced postoperative infectious complications (relative risk 0.65, 95% confidence interval [CI] 0.45-0.94) and low-quality evidence on reducing the length of hospital stay (mean difference 0.87, 95% CI 0.17-1.58) compared with control. A single trial demonstrated an effect of multimodal prehabilitation on postoperative complication. CONCLUSION: Nutrition prehabilitation was effective in reducing infectious complications and length of hospital stay. Whether other multimodal, exercise, and psychological prehabilitation modalities improve postoperative outcomes after colorectal cancer surgery is uncertain as the current quality of evidence is low.

RESUMEN
BACKGROUND: Information on the course of quality of life after surgery for advanced cancers within the pelvis is important to guide patient decision-making; however, the current evidence is limited. OBJECTIVE: To identify quality-of-life trajectory classes and their predictors after pelvic exenteration. DESIGN: Prospective cohort study. SETTINGS: Highly specialized quaternary pelvic exenteration referral center. PATIENTS: Patients undergoing pelvic exenteration due to advanced/recurrent cancers within the pelvis between July 2008 and July 2022. MAIN OUTCOME MEASURES: Quality-of-life data included the 36-item Short-Form Survey (physical and mental component scores) and the Functional Assessment of Cancer Therapy-Colorectal instruments, which were collected at 11 distinct points from baseline to 5 years postoperatively. Predictors included patient characteristics and surgical outcomes. Latent class analysis was used to identify the likelihood of a better quality-of-life class, and logistic regression models were used to identify predictors of the identified classes. RESULTS: The study included 565 participants. Two distinct quality-of-life trajectory classes were identified for the Physical Component Score (class 1: high stable and class 2: high decreasing). Three distinct classes were identified for the Mental Component Score (class 1: high increasing, class 2: moderate stable, and class 3: moderate decreasing) and for Functional Assessment of Cancer Therapy-Colorectal total score (class 1: high increasing, class 2: high decreasing, and class 3: low decreasing). Across the 3 quality-of-life domains, overall survival probabilities were also higher in class 1 ( p < 0.0001). Age, repeat exenteration, neoadjuvant therapy, surgical margin, length of operation, and hospital stay were significant predictors of quality-of-life classes. LIMITATIONS: This study was conducted at a single highly specialized quaternary pelvic exenteration referral center, and findings may not apply to other centers. CONCLUSIONS: This study demonstrates that quality of life after pelvic exenteration diverges into distinct trajectories, with most patients reporting an optimal course. See Video Abstract . TRAYECTORIAS EN LA CALIDAD DE VIDA DESPUS DE EXENTERACIN PLVICA ANLISIS DE CRECIMIENTO DE CLASES LATENTES: ANTECEDENTES:La información sobre la evolución en la calidad de vida después de cirugía en cánceres avanzados situados en la pelvis es importante para guiar la toma de decisiones sobre el paciente; sin embargo, la evidencia actual es muy limitada.OBJETIVO:Identificar las clases de trayectorias en la calidad de vida y sus factores pronóstico después de la exenteración pélvica.DISEÑO:Estudio de cohortes prospectivo.AJUSTES:Centro de referencia altamente especializado en la exenteración pélvica cuaternaria.PACIENTES:Todos aquellos sometidos a exenteración pélvica por cáncer avanzados/recurrentes situados en la pelvis entre Julio de 2008 y Julio de 2022.PRINCIPALES MEDIDAS DE RESULTADO:Los datos sobre la calidad de vida incluyeron el Cuestionario de Salud SF-36 (puntuaciones de componentes físicos y mentales) y la evaluación funcional entre la terapia del cáncer/-herramientas colorrectales, recopilados en 11 puntos distintos desde el diagnóstico hasta los 5 años después de la operación.Los predictores incluyeron las características de los pacientes y los resultados quirúrgicos. Se utilizó el análisis de clases latentes para identificar la probabilidad de una mejor calidad de vida y se utilizaron modelos de regresión logística para identificar predictores de las clases identificadas.RESULTADOS:El estudio incluyó a 565 participantes. Se identificaron dos clases distintas de trayectorias de calidad de vida para la puntuación del componente físico (clase 1: alta estable y clase 2: alta decreciente), se identificaron tres clases distintas para la puntuación del componente mental (clase 1: alta creciente; clase 2: moderadamente estable; y clase 3: moderada disminución) y para la evaluación funcional de la terapia contra el cáncer-puntuación total colorrectal (clase 1: aumento alto; clase 2: disminución alta; y clase 3: disminución baja). En los tres dominios de calidad de vida, las probabilidades de supervivencia general también fueron mayores en las clases 1 (p <0,0001). La edad, las exenteraciones pélvicas repetidas, la terapia neoadyuvante, el margen quirúrgico, la duración de la operación y la estadía hospitalaria fueron predictores significativos en las clases de calidad de vida.LIMITACIONES:El presente estudio fué realizado en un único centro de referencia altamente especializado en exenteración pélvica cuaternaria y es posible que los hallazgos no se apliquen a otros centros.CONCLUSIONES:Demostramos con nuestro estudio que la calidad de vida después de la exenteración pélvica diverge en trayectorias distintas, y que la mayoría de los pacientes nos reportaron de una évolución óptima.

INTRODUCTION: Over the last decade, the number of prehabilitation randomised controlled trials (RCTs) has increased significantly. Therefore, this review aimed to describe the outcomes reported in prehabilitation RCTs in patients undergoing cancer surgery. METHODS: A search was conducted in Embase, Allied and Complementary Medicine Database, The Cochrane Library, PsycINFO, MEDLINE, and Cumulated Index to Nursing and Allied Health Literature from inception to July 2021. We included RCTs evaluating the effectiveness of preoperative exercise, nutrition, and psychological interventions on postoperative complications and length of hospital stay in adult oncology patients who underwent thoracic and gastrointestinal cancer surgery. The verbatim outcomes reported in each article were extracted, and each outcome was assessed to determine whether it was defined and measured using a validated tool. Verbatim outcomes were grouped into standardized outcomes and categorized into domains. The quality of outcome reporting in each identified article was assessed using the Harman tool (score range 0-6, where 0 indicated the poorest quality). RESULTS: A total of 74 RCTs were included, from which 601 verbatim outcomes were extracted. Only 110 (18.3%) of the verbatim outcomes were defined and 270 (44.9%) were labeled as either "primary" or "secondary" outcomes. Verbatim outcomes were categorized into 119 standardized outcomes and assigned into one of five domains (patient-reported outcomes, surgical outcomes, physical/functional outcomes, disease activity, and intervention delivery). Surgical outcomes were the most common outcomes reported (n = 71 trials, 95.9%). The overall quality of the reported outcomes was poor across trials (median score: 2.0 [IQR = 0.00-3.75]). CONCLUSIONS: Prehabilitation RCTs display considerable heterogeneity in outcome reporting, and low outcome reporting quality. The development of standardized core outcome sets may help improve article quality and enhance the clinical utility of prehabilitation following cancer surgery.

INTRODUCTION: The views of patients and carers are important for the development of research priorities. This study aimed to determine and compare the top research priorities of cancer patients and carers with those of multidisciplinary clinicians with expertise in prehabilitation. MATERIALS AND METHODS: This cross-sectional study surveyed patients recovering from cancer surgery at a major tertiary hospital in Sydney, Australia, and/or their carers between March and July 2023. Consenting patients and carers were provided a list of research priorities according to clinicians with expertise in prehabilitation, as determined in a recent International Delphi study. Participants were asked to rate the importance of each research priority using a 5-item Likert scale (ranging from 1 = very high research priority to 5 = very low research priority). RESULTS: A total of 101 patients and 50 carers participated in this study. Four areas were identified as research priorities, achieving consensus of highest importance (> 70% rated as "high" or "very high" priority) by patients, carers, and clinical experts. These were "optimal composition of prehabilitation programs" (77% vs. 82% vs. 88%), "effect of prehabilitation on surgical outcomes" (85% vs. 90% vs. 95%), "effect of prehabilitation on functional outcomes" (83% vs. 86% vs. 79%), and "effect of prehabilitation on patient reported outcomes" (78% vs. 84% vs. 79%). Priorities that did not reach consensus of high importance by patients despite reaching consensus of highest importance by experts included "identifying populations most likely to benefit from prehabilitation" (70% vs. 76% vs. 90%) and "defining prehabilitation core outcome measures" (66% vs. 74% vs. 87%). "Prehabilitation during neoadjuvant therapies" reached consensus of high importance by patients but not by experts or carers (81% vs. 68% vs. 69%). CONCLUSION: This study delineated the primary prehabilitation research priorities as determined by patients and carers, against those previously identified by clinicians with expertise in prehabilitation. It is recommended that subsequent high-quality research and resource allocation be directed towards these highlighted areas of importance.

BACKGROUND: Rural Australians typically encounter disparities in healthcare access leading to adverse health outcomes, delayed diagnosis and reduced quality of life (QoL) parameters. These disparities may be exacerbated in advanced malignancies, where treatment is only available at highly specialised centres with appropriate multidisciplinary expertise. Thus, this study aims to determine the association between patient residence on oncological, surgical and QoL outcomes following cytoreductive surgery (CRS) and hyperthermic intra-peritoneal chemotherapy (HIPEC). METHODS: A retrospective analysis was conducted on consecutive patients undergoing CRS and HIPEC at Royal Prince Alfred Hospital from January 2017 to March 2022. On the basis of their postcode of residence, patients were stratified into metropolitan and regional groups. Data encompassing demographics, oncological, surgical and QoL outcomes were compared. Statistical analysis included chi-square test, t-tests and Kaplan-Meier survival curves. RESULTS: Among the 317 patients, 228 (72%) were categorised as metropolitan and 89 (28%) as regional. Metropolitan patients presented higher rates of recurrence (61.8% versus 40.0%, p = 0.014) and shorter overall mean survival [3.8 years (95% CI: 3.44-4.09) versus 4.2 years (95% CI: 3.76-4.63), p = 0.019] compared with regional patients. No other statistically significant differences were observed in oncological, surgical and QoL outcomes. CONCLUSIONS: Most oncological, surgical and QoL parameters did not differ by geographical location of patients undergoing CRS and HIPEC for peritoneal malignancies at a high-volume quaternary referral centre. Observed differences in recurrence and survival may be attributed to the selective nature of surgical referrals and variable follow-up patterns. Future research should focus on characterising referral pathways and its influence on post-operative outcomes.

BACKGROUND: This review aimed to determine outcomes following megaprostheses in non-oncological indications for knee arthroplasty, including range of motion (ROM) and patient-reported outcome measures of function, pain, and quality of life (QoL). METHODS: A search of MEDLINE, Embase, and Cochrane via Ovid and PubMed between January 2003 and June 2023 was conducted. Studies reporting function, pain, ROM, and/or QoL in non-oncological patients who have received knee megaprostheses were included. Studies with sample sizes (n ≤ 5) were excluded. The risk of bias was assessed using the Downs and Black Quality Checklist for Health Care Intervention Studies. Central tendency measures (mean or median) were reported at each time point, and dispersion measures were extracted and reported whenever data were available. RESULTS: A total of 30 studies (involving 1,294 megaprostheses) were included. Of which, 14 of 30 studies reviewed patients who had mixed indications; 14 of 30 looked at fracture only; 1 of 30 focused on distal femur nonunion; and 1 of 30 focused on patients who had periprosthetic infections. The average patient follow-up time was 40.1 months (range, 1.0 to 93.5). Most studies presented a high risk of bias (27 of 30), while a few (3 of 30) presented a low risk of bias. Improvements from preoperative baseline were observed in 85.7% of studies that reported baseline and follow-up data for function (12 of 14), 100.0% pain (4 of 4), 90.9% ROM (10 of 11), and 66.6% QoL (2 of 3). CONCLUSIONS: Favorable function, pain, ROM, and QoL outcomes following knee megaprostheses in non-oncological patients were observed. Heterogeneity in outcome measures and follow-up periods prevented the pooling of data. Future comparative studies are warranted to enhance the body of evidence relating to knee megaprostheses in non-oncological patients.
RESUMEN
PURPOSE: Robotic-assisted total knee arthroplasty (TKA) may improve the precision of bone preparation and component alignment when compared to the conventional surgical approach; however, the detailed cost analysis of robotic-assisted TKA is lacking. This study aims to compare in-hospital costs between robotic-assisted and computer-navigated TKA. METHODS: Patients undergoing primary TKA at a public hospital in Sydney between October 2018 and June 2019 were included. Patient demographics, surgical outcomes and in-hospital cost variables including, staff, critical care, emergency department, diagnostic, prosthesis, operating room, ward and other related costs until the discharge to the community were collected. Differences across in-hospital costs between robotic-assisted and computer-navigated TKA were compared using independent Student's t-tests. RESULTS: Of the 258 primary TKAs, 181 (70.2%) were computer-navigated and 77 (29.8%) robotic-assisted. Surgical time (p < 0.001) and operating time (p < 0.001) were both significantly shorter in computer-navigated TKA, while robotic-assisted TKA cases were more likely to be discharged directly home without extended in-patient rehabilitation (p = 0.014). When removing the capital costs of surgical equipment and maintenance, there was no difference in total in-hospital cost between computer-navigated ($19,512.3) and robotic-assisted TKA ($18,347.1; p = 0.179). When these capital costs were included, the mean in-hospital cost of robotic-assisted surgery was $21,507.6 compared to $19,659.7 for computer-navigated TKA (p = 0.034). CONCLUSIONS: The total in-hospital cost, during the implementation period of robotic-assisted TKA, is comparable with computer-navigated TKA. Robotic-assisted TKA was significantly more expensive when the upfront cost of the robotic system and maintenance costs were included. Longer term cost benefit of robotic-assisted TKA should be investigated in future studies.

BACKGROUND: Total knee arthroplasty (TKA) is widely considered a successful intervention for osteoarthritis and other degenerative knee diseases. This study addresses the need for a high-quality meta-analysis that outlines the clinical course of pain and function post-TKA. METHODS: The review included prospective cohort studies assessing pain or function of patients undergoing primary TKA at baseline (preoperatively) and at least 2 additional time points including one at least 12 months postoperatively. Two reviewers independently screened references, extracted data, and assessed risk of bias using the Quality in Prognosis Studies tool. The time course of recovery of pain and function was modeled using fractional polynomial meta-regression. RESULTS: In total, 191 studies with 59,667 patients were included, most with low risk of bias. The variance-weighted mean pain score (/100, 0 = no pain) was 64.0 (95% confidence interval [CI] 60.2-67.7) preoperatively, 24.1 (95% CI 20.3-27.9) at 3 months, 20.4 (95% CI 16.7-24.0) at 6 months, and 16.9 (95%CI 13.6-20.3) at 12 months, and remained low (10.1; 95% CI 4.8-15.4) at 10 years postoperatively. The variance-weighted mean function score (/100, 0 = worst function) was 47.1 (95% CI 45.7-48.4) preoperatively, 72.8 (95% CI 71.3-74.4) at 3 months, 76.3 (95% CI 74.7-77.8) at 6 months, and 78.1 (95%CI 76.4-79.7) at 12 months. Function scores were good (79.7; 95% CI 77.9-81.5) at 10 years postoperatively. CONCLUSION: Patients undergoing primary TKA can expect a large and rapid but incomplete recovery of pain and function in the first postoperative year. At 10 years, the gains in pain scores may still remain while there is an improvement in function.

BACKGROUND: Subacromial analgesia (SAA) is hypothesized to reduce pain after arthroscopic shoulder surgery by delivering a continuous infusion of local anesthetic directly to the surgical site. The purpose of this systematic review and meta-analysis was to evaluate the efficacy of SAA vs. placebo for pain relief after arthroscopic subacromial shoulder procedures. METHODS: MEDLINE, Embase, PubMed, and the Cochrane Central Register of Controlled Trials were searched for randomized controlled trials comparing SAA with placebo after arthroscopic shoulder surgery. Outcomes collected included pain scores (converted to equivalent ordinal visual analog scores; minimal clinically important difference 1.4 cm), oral morphine equivalents used postoperatively, and catheter-related complications. Meta-analysis was performed via a random-effects model. Included trials underwent a risk of bias and quality of evidence assessment. RESULTS: Nine studies involving 459 participants were included. There were no clinically significant changes for pain scores in SAA at 6-, 12-, 24-, and 48-hour postoperative timepoints. Patients receiving SAA used less morphine equivalents of pain medication at 12 hours only (-0.37 mg, 95% confidence interval: -0.63 to -0.11), but there was no significant difference at 24 and 48 hours. There were no major complications (infection or reoperation). Included trials demonstrated a moderate risk-of-bias, and low to very low quality of evidence for primary outcomes. CONCLUSION: Subacromial continuous infusion of local anesthetic does not provide a clinically significant benefit compared with placebo as part of a multimodal analgesia regime after arthroscopic subacromial surgical procedures. Future, high-quality trials are required to further assess the efficacy of SAA against placebo.

PURPOSE: The purpose of the study is to determine the effectiveness of semi-active and active robotic hip and knee arthroplasty on post-operative patient-reported outcomes of function, pain, quality of life and satisfaction with surgery. METHODS: PubMed, Medline, Embase and CENTRAL were searched. Included were comparative studies investigating the effectiveness of semi-active or active robotic hip or knee arthroplasty compared to any other surgical intervention on function, pain, quality of life and satisfaction with surgery. Risk of bias and the strength of the evidence were assessed using the Downs and Black tool and the GRADE system, respectively. Relative risks, mean differences and 95% CI were calculated using random-effects models. RESULTS: Fourteen studies involving 1342 patients were included. All studies compared robotic to conventional surgery, with active robotic surgery evaluated in total hip or knee arthroplasty and semi-active robotic surgery in total hip or unicompartmental knee arthroplasty. Most studies presented some risk of bias, and the strength of evidence was rated as low to very low quality. Random-effects meta-analyses showed that post-operative functional outcomes were comparable between active robotic and conventional total hip and knee arthroplasty at the short-, medium- and long-term follow-up. No significant difference in pain, quality of life and satisfaction with surgery were reported in individual studies. CONCLUSIONS: This systematic and meta-analyses indicates that functional outcomes for patients undergoing active robotic total hip and knee arthroplasty were comparable to conventional surgery. Whether semi-active or active robotic hip or knee arthroplasty is effective in improving post-operative pain, quality of life and satisfaction with surgery is unclear.

BACKGROUND: To formulate a hierarchy of primary goals of patients prior to total knee arthroplasty (TKA) and evaluate the agreement between patients and health professionals regarding this hierarchy of patient goals. METHODS: The five most important goals for each of 110 consecutive patients booked for total knee arthroplasty between June and October 2019 were identified. Goals were grouped into themes and then a hierarchy formulated. This hierarchy was randomized and provided to 94 health professionals, including orthopaedic surgeons (n = 49), rheumatologists (n = 16), physiotherapists (n = 16) and general practitioners (n = 13). These health professionals ranked the provided goals based on their belief of what was most important to patients. RESULTS: Ten overarching goals were identified, with the five most important goals to patients being improving mobility, reducing knee pain, improving daily tasks, participating in social & leisure activities and regaining knee range of motion. Health professionals ranked these goals highly similar to patients with the exceptions being that health professionals ranked quality of life near the top of the hierarchy (much higher than patients) and ranked improving mobility in the bottom half (much lower than patients). Ranking of these goals was similar between each health professional group. CONCLUSION: Pain and mobility are the most important goals to patients, with health professionals correctly identifying these as such. However, health professionals ranked quality of life higher, and mobility lower in the hierarchy than patients. This incongruity should be considered by health professionals when educating and communicating treatment outcomes.

BACKGROUND: Total knee arthroplasty (TKA) is a common procedure employed to treat end-stage osteoarthritis. While TKA is generally believed to have acceptable outcomes, many patients report pain or functional deficits not in line with their expectation following the procedure. It has been postulated that patient's pre-operative expectations regarding post-operative treatment outcomes play a significant role in satisfaction. It is therefore important to assess if the outcomes of surgery truly align with patient's individual expectations. Thus, the purpose of this study was to determine the degree to which patient expectations of TKA are achieved and the contribution of TKA to achieving patient goals one year after surgery. METHODS: A consecutive sample of 110 patients booked for total knee arthroplasty were asked to identify their most important goals to inform the Direct Questioning of Objectives Index (DQO Index, range 0 to 1) and identify their surgical goals and grade their expectation that a knee arthroplasty would achieve each goal on an 11-point scale. One year after surgery, the DQO Index was repeated to assess their current ability to achieve each pre-operative goal, and asked to estimate the contribution of their knee arthroplasty in achieving each goal. Mean differences between baseline and one year follow-up were calculated regarding the DQO Index and expected achievement of pre-operative goals. RESULTS: According to the DQO Index at one year, patients improved from a poor quality of life pre-operatively (mean ± standard deviation: 0.20 ± 0.18) to moderately high quality of life (mean ± standard deviation: 0.71 ± 0.21) reflecting a large improvement in ability to achieve each goal. Although achievement improved, for each goal, the patient estimates of the extent to which the knee arthroplasty had contributed to achieving the goal was lower than their initial expectation provided pre-operatively (mean difference range: 0.6 to 1.9 on an 11-point scale). CONCLUSION: Patients undergoing TKA have high expectations that their surgery will address their primary goals. Despite surgery largely achieving these goals (improved pain and function), the extent to which the goals were achieved was lower than patients had expected pre-operatively.

BACKGROUND: This study describes surgical and quality of life outcomes in patients with peritoneal malignancy treated by cytoreductive surgery (CRS) alone compared with a subgroup treated with CRS and hyperthermic intraperitoneal chemotherapy (HIPEC). METHODS: Peritoneal malignancy patients undergoing surgery between 2017 and 2023 were included. The cohort was divided into patients treated by CRS and HIPEC and those treated by CRS without HIPEC (including CRS only or maximal tumour debulking (MTB)). Main outcomes included surgical outcomes, survival, and quality of life. Groups were compared using non-parametric tests and log-rank test was used to compare survival curves. RESULTS: 403 had CRS and HIPEC, 25 CRS only and 15 MTB. CRS and HIPEC patients had a lower peritoneal carcinomatosis index (12.0 vs. 17.0 vs. 35.0; P < 0.001) and longer surgical operative time (9.3 vs. 8.3 vs. 5.2 h; P < 0.001), when compared to CRS only and MTB, respectively. No other significant difference between groups was observed. CONCLUSIONS: The optimal management of selected patients with resectable peritoneal malignancy incorporates a combined strategy of CRS and HIPEC. When HIPEC is not utilized, due to significant residual disease or comorbidity precluding safe delivery, CRS alone is associated with good outcomes. Hospital stay and complications are acceptable but not significantly different to the CRS and HIPEC group. CRS alone is a complex intervention requiring comparable resources with good outcomes. In view of our findings 'intention to treat' with CRS and HIPEC should be the basis for resource allocation and funding.

As uptake of robotic-assisted arthroplasty increases there is a need for economic evaluation of the implementation and ongoing costs associated with robotic surgery. The aims of this study were to describe the in-hospital cost of robotic-assisted total knee arthroplasty (RA-TKA) and robotic-assisted unicompartmental knee arthroplasty (RA-UKA) and determine the influence of patient characteristics and surgical outcomes on cost. This prospective cohort study included adult patients (≥ 18 years) undergoing primary unilateral RA-TKA and RA-UKA, at a tertiary hospital in Sydney between April 2017 and June 2021. Patient characteristics, surgical outcomes, and in-hospital cost variables were extracted from hospital medical records. Differences between outcomes for RA-TKA and RA-UKA were compared using independent sample t-tests. Logistic regression was performed to determine drivers of cost. Of the 308 robotic-assisted procedures, 247 were RA-TKA and 61 were RA-UKA. Surgical time, time in the operating room, and length of stay were significantly shorter in RA-UKA (p < 0.001); whereas RA-TKA patients were older (p = 0.002) and more likely to be discharged to in-patient rehabilitation (p = 0.009). Total in-hospital cost was significantly higher for RA-TKA cases (AU$18580.02 vs $13275.38; p < 0.001). Robotic system and maintenance cost per case was AU$3867.00 for TKA and AU$5008.77 for UKA. Patients born overseas and lower volume robotic surgeons were significantly associated with higher total cost of RA-UKA. Increasing age and male gender were significantly associated with higher total cost of RA-TKA. Total cost was significantly higher for RA-TKA than RA-UKA. Robotic system costs for RA-UKA are inflated by the software cost relative to the volume of cases compared with RA-TKA. Cost is an important consideration when evaluating long term benefits of robotic-assisted knee arthroplasty in future studies to provide evidence for the economic sustainability of this practice.

Aims: Custom triflange acetabular components (CTACs) play an important role in reconstructive orthopaedic surgery, particularly in revision total hip arthroplasty (rTHA) and pelvic tumour resection procedures. Accurate CTAC positioning is essential to successful surgical outcomes. While prior studies have explored CTAC positioning in rTHA, research focusing on tumour cases and implant flange positioning precision remains limited. Additionally, the impact of intraoperative navigation on positioning accuracy warrants further investigation. This study assesses CTAC positioning accuracy in tumour resection and rTHA cases, focusing on the differences between preoperative planning and postoperative implant positions. Methods: A multicentre observational cohort study in Australia between February 2017 and March 2021 included consecutive patients undergoing acetabular reconstruction with CTACs in rTHA (Paprosky 3A/3B defects) or tumour resection (including Enneking P2 peri-acetabular area). Of 103 eligible patients (104 hips), 34 patients (35 hips) were analyzed. Results: CTAC positioning was generally accurate, with minor deviations in cup inclination (mean 2.7°; SD 2.84°), anteversion (mean 3.6°; SD 5.04°), and rotation (mean 2.1°; SD 2.47°). Deviation of the hip centre of rotation (COR) showed a mean vector length of 5.9 mm (SD 7.24). Flange positions showed small deviations, with the ischial flange exhibiting the largest deviation (mean vector length of 7.0 mm; SD 8.65). Overall, 83% of the implants were accurately positioned, with 17% exceeding malpositioning thresholds. CTACs used in tumour resections exhibited higher positioning accuracy than rTHA cases, with significant differences in inclination (1.5° for tumour vs 3.4° for rTHA) and rotation (1.3° for tumour vs 2.4° for rTHA). The use of intraoperative navigation appeared to enhance positioning accuracy, but this did not reach statistical significance. Conclusion: This study demonstrates favourable CTAC positioning accuracy, with potential for improved accuracy through intraoperative navigation. Further research is needed to understand the implications of positioning accuracy on implant performance and long-term survival.
RESUMEN
Background/Objectives: The presence of seminal vesicle invasion (SVI) in prostate cancer (PCa) is associated with poorer postoperative outcomes. This study evaluates the predictive value of magnetic resonance imaging (MRI) and prostate-specific membrane antigen positron emission tomography/computed tomography (PSMA PET/CT) for SVI in PCa. Methods: This cohort study included consecutive robotic prostatectomy patients for PCa at three Australian tertiary referral centres between April 2016 and September 2022. MRI and PSMA PET/CT results, clinicopathological variables, including age, BMI, prostate-specific antigen (PSA), PSA density, DRE, Biopsy Gleason score, Positive biopsy cores, PIRADS v2.1 score, MRI volume and MRI lesion size were extracted. The sensitivity, specificity, and accuracy of MRI and PSMA PET/CT for predicting SVI were compared with the histopathological results by receiver operating characteristic (ROC) analysis. Subgroup univariate and multivariate analysis was performed. Results: Of the 528 patients identified, 86 had SVI on final pathology. MRI had a low sensitivity of 0.162 (95% CI: 0.088-0.261) and a high specificity of 0.963 (95% CI: 0.940-0.979). The PSMA PET/CT had a low sensitivity of 0.439 (95% CI: 0.294-0591) and a high specificity of 0.933 (95% CI: 0.849-0.969). When MRI and PSMA PET/CT were used in combination, the sensitivity and specificity improved to 0.514 (95%CI: 0.356-0.670) and 0.880 (95% CI: 0.813-0.931). The multivariate regression showed a higher biopsy Gleason score (p = 0.033), higher PSA (p < 0.001), older age (p = 0.001), and right base lesions (p = 0.003) to be predictors of SVI. Conclusions: MRI and PSMA PET/CT independently underpredicted SVI. The sensitivity and AUC improved when they were used in combination. Multiple clinicopathological factors were associated with SVI on multivariate regression and predictive models incorporating this information may improve oncological outcomes.
RESUMEN
BACKGROUND: Reconstructive procedure following resection of large pelvic tumours around the hip joint remains a complex challenge. METHODS: This study presents a retrospective case series of patients presenting with benign or malignant pelvic tumour for which an internal hemipelvectomy including the hip joint and subsequent reconstruction with a custom designed 3-dimensional printed titanium pelvic implant (3DPPI) has been performed between August 2013 and January 2018. RESULTS: 15 consecutive patients with a median age of 33.9 years (IQR 26.4-72.2) and a median BMI of 20.7 kg/m2 (IQR 19.0-33.3) were reviewed after median follow-up of 33.8 months (IQR 24.0-78.1). The majority of patients presented with a malignant tumour as their principal diagnosis (n = 13, 86.7%). The median surgical time was 5.5 hours (IQR 4.5-8.5) and median peri-operative blood loss was 5000 ml (IQR 2000-10000). The median MSTS score at follow-up was 63.3% (IQR 51.7-86.7%). The median NRS in rest was 0.0 (IQR 0.0-5.0), the median NRS during activity was 2.0 (IQR 0.5-7.0) and the median HOOS-PS was 76.6% (IQR 67.9-91.0). 4 patients had implant-specific complications (n = 4, 26.6%); 1 hip dislocation (Henderson type 1a), 3 structural complications (type 3a), 1 deep infection (type 4a) and 1 local tumour recurrence (type 5b). At follow-up, 4 out of 15 implants were classified as a failure, resulting in an implant survival rate of 73.3%. CONCLUSIONS: Acceptable peri-operative outcomes, functional results, complication rates and short-term implant survival can be achieved in a cohort of complex patients undergoing 3DPPI reconstruction after hemipelvectomy including the acetabulum.

Patient-reported outcome measures (PROMs) are a vital part of the toolkit for the current practice of orthopedic surgery. We are witnessing the expansion of the use of PROMs in clinical practice and in research; the ultimate direction of this expansion is unclear. The purpose of this systematic review was to identify the trends in the use of PROMs in major upper limb publications over a 7-year period. We retrospectively reviewed all articles published in 6 of the most influential upper limb orthopedic journals based on impact factor from January 2013 to January 2020. PubMed, Medline, and Embase were used to access the abstracts for all articles published for this period. We included all articles related to shoulder arthroplasty, shoulder instability, rotator cuff surgery, and involving the use of PROMs. There were 4175 articles identified from the selected journals over the chosen time period, of which 607 were eligible for inclusion in the study. The number of articles reporting PROMs increased from 57 in 2013 to 115 in 2019, which was a 102% increase. The total number of PROM usages recorded was 1593 which was comprised of 63 different scoring systems, with each article using a median of 3 different PROMs. The most commonly used score in articles originating from North America was the American Shoulder and Elbow Surgeons score (216 uses in 273 articles; 78.1%), from Europe it was the Constant-Murley Score (129 uses in 183 articles; 70.4%), and from Asia it was the American Shoulder and Elbow Surgeons score (80 uses in 126 articles; 63.4%). The use of PROMs is evolving with an increasing prevalence of and diversity of PROMs being used in upper limb surgery. There is geographical variation in the use of PROMs, and a variety of systems used, with only 3 of the top 10 most used PROMs reporting on patient satisfaction or wellbeing. Given that a diverse range of PROMs study a diverse range of conditions and procedures, there may not be a need for a consensus on the best overall use of PROMs, but there may be ideal PROMs suited to answer specific questions.
RESUMEN
Aims: Tenosynovial giant cell tumour (TGCT) is a rare benign tumour of the musculoskeletal system. Surgical management is fraught with challenges due to high recurrence rates. The aim of this study was to describe surgical treatment and evaluate surgical outcomes of TGCT at an Australian tertiary referral centre for musculoskeletal tumours and to identify factors affecting recurrence rates. Methods: A prospective database of all patients with TGCT surgically managed by two orthopaedic oncology surgeons was reviewed. All cases irrespective of previous treatment were included and patients without follow-up were excluded. Pertinent tumour characteristics and surgical outcomes were collected for analysis. Results: There were 111 total cases included in the study; 71 (64%) were female, the mean age was 36 years (SD 13.6), and the knee (n = 64; 57.7%) was the most commonly affected joint. In all, 60 patients (54.1%) had diffuse-type (D-TGCT) disease, and 94 patients (84.7%) presented therapy-naïve as "primary cases" (PC). The overall recurrence rate was 46.8% for TGCT. There was a statistically significant difference in recurrence rates between D-TGCT and localized disease (75.0% vs 13.7%, relative risk (RR) 3.40, 95% confidence interval (CI) 2.17 to 5.34; p < 0.001), and for those who were referred in the "revision cases" (RC) group compared to the PC group (82.4% vs 48.9%, RR 1.68, 95% CI 1.24 to 2.28; p = 0.011). Age, sex, tumour volume, and mean duration of symptoms were not associated with recurrence (p > 0.05). Conclusion: Recurrence rates remain high even at a tertiary referral hospital. Highest rates are seen in D-TGCT and "revision cases". Due to the risks of recurrence, the complexity of surgery, and the need for adjuvant therapy, this paper further supports the management of TGCT in a tertiary referral multi-disciplinary orthopaedic oncology service.
