Abstract
BACKGROUND Reduction mammoplasty and mastopexy are potentially complicated by prior breast irradiation as part of breast conserving therapy. Associated tissue changes with therapeutic irradiation have led to surgeons deciding the risks may outweigh potential benefit for those patients. A systematic review of the existing literature was performed to explore surgical outcomes of patients undergoing delayed bilateral reduction mammoplasty or mastopexy following unilateral breast irradiation as part of breast conserving therapy. METHODS Medline, PubMed and EMBASE were searched from 1990 to 2023 according to PRISMA guidelines. Studies were combined by the generic inverse variance method on the natural logarithms of rate ratios (RR) using a random effect model in Review manager 5.4.1. RESULTS Fifteen studies reported outcomes in 188 patients who underwent breast reduction (BR) following unilateral breast conserving surgery and radiotherapy. The median age at BR was 51.5 years (range 39-60), and median time since radiotherapy was 48 months (range 11.7-86). We compared outcomes for irradiated breast (IB) versus non-irradiated breast (NIB). Pooled results showed higher rate of major complications in the IB (RR 2.52, 95%CI 0.96-6.63, p=0.06), but not statistically significant. However, rate of minor complications was significantly higher in the IB (RR 3.97 95%CI 1.86-8.50, p<0.0004). Incidence of fat necrosis as a discrete complication was 2× higher in IB (RR 2.14 95%CI 0.85-5.35, p-value 0.10) compared to the NIB, but not significant. CONCLUSION We found breast reduction to be safe with acceptable risk of major complications. However, the overall complication rate remains higher in IB compared to NIB.

Abstract
BACKGROUND Mechanical alignment with total knee arthroplasty (TKA) has been widely used since the implantation of the first prosthetic knee. Multiple studies have reported 80% patient satisfaction with TKA. However, the reported patients' dissatisfaction is believed to be caused by having to convert different knee alignments to neutral alignments. It is postulated that a change in the CPAK classification of knees leads to patient dissatisfaction. Thus, we hypothesized that a change in CPAK classification with robot-assisted TKA with mechanical alignment does not significantly lead to patient dissatisfaction. METHODS We retrospectively analyzed 134 patients who underwent robot-assisted mechanical alignment total knee arthroplasty (MA-TKA) using cementless implants and classified them into CPAK system pre- and post-operatively. One year after TKA surgery, we recorded binary responses to patients' satisfaction with the outcome of surgery and analyzed if a change in CPAK classification is associated with the outcome of surgery. RESULTS We found that 125 out of 134 patients (93.28%) were happy with the outcome of surgery. CPAK classification was changed in 116 patients (86.57%) and maintained in 18 patients (13.43%). Our results also showed that 111 (95.7%) out of 116 patients who had a change in CPAK and 14 (77.8%) out of 18 patients who maintained their CPAK post-surgery were happy with the outcome of surgery (OR = 6.3, CI 1.741-25.17, P value = 0.019). CONCLUSION We concluded that changing the patient's native joint line and CPAK classification does not significantly change the outcome of surgery in terms of satisfaction. The dissatisfaction rate of 20% as published by previous researchers may be confounded by other reasons and not just due to changes in alignment and joint line.

Abstract
Several studies reported that20% of patients were unhappy with the outcome of their total knee arthroplasty (TKA). Having commenced robot assist TKA whilst maintaining the goal of implanting the prosthesis to a neutral mechanical axis, we reviewed our patients to find out if we also have a 20% rate of patients being unhappy with the outcome of their knee replacement surgery. We hypothesized that rate of patient satisfaction would be higher than 90% with robot-surgical assistant (ROSA) technique. The first 175 patients who underwent ROSA TKA were reviewed at a minimum of 1 year postoperatively. All TKAs were performed using ROSA technique with Persona cementless prosthesis aiming to restore neutral mechanical coronal alignment with flexion gap balancing. We investigated whether or not the patients were happy they had their knee replacement surgery and whether they were happy with the outcome. 165 (94%) of 175 patients, were contactable with 1 deceased and 9 uncontactable. From the 165 patients who participated in the study, 95% of patients were happy they had the surgery done and 93% were happy with the outcome of their knee replacement. A sub analysis showed that patients who had simultaneous bilateral TKA were significantly less likely to be happy than staged procedures (p < 0.05). Total knee replacement utilising robot technique with modern implants and aiming for mechanical coronal alignment of the implants to restore the mechanical axis with flexion gap balancing may result in > 90% of patients being happy with the outcome of their surgery.

Abstract
BACKGROUND An association between breast cancer and meningioma has been suggested in cohort studies. We aimed to perform a systematic review and meta-analysis to determine whether there is an association between initial breast cancer and subsequent meningioma diagnosis and vice versa. METHODS A systematic literature search was performed on Medline, Embase, Scopus and Google scholar from inception up to April 2023. A meta-analysis of selected studies was performed using Review Manager 5.4. RESULTS There were eight studies included in the systematic review. Seven had reported Standardized Incidence Ratio (SIR) for female patients and were suitable for the meta-analysis. Only one study reported SIR for male patients. For the association between initial breast cancer and subsequent meningioma, in 795 000 female patients with follow-up ranging from 7 to 13 years, the SIR was 1.27 (95% CI: 1.20-1.34, P-value <0.00001). For the association between initial meningioma and subsequent breast cancer, in 28 000 female patients with follow-up ranging from 6 to 15 years, the SIR was 1.32 (95% CI: 1.21-1.45, P-value <0.00001). There were low heterogeneity and no significant publication bias. CONCLUSION There was a small but significant association between initial breast cancer and subsequent meningioma as well as initial meningioma and subsequent breast cancer in female patients. The potential underlying mechanisms and risk factors were unclear from current literature and would be a potential area for future research.

Abstract
BACKGROUND TSH receptor autoantibodies (TRAbs) are pathognomonic for Graves' disease and are thought to also underly the pathogenesis of Graves' ophthalmopathy (GO). A decline in TRAb levels has been documented post-total thyroidectomy (TTx) in GO, however with conflicting correlations with disease outcomes. The aim of the study was to compare the effectiveness of TTx to other treatment modalities of Graves' disease and examine whether the lowering of TRAbs is associated with GO improvements. METHOD We searched electronic databases including Medline, Embase, Scopus, and Web of Science until 31 September 2022 using a broad range of keywords. Patients with GO undergoing TTx with measurements of both TRAbs and progression of the disease using a validated GO scoring system were included. Fourteen studies encompassing data from 1047 patients with GO met our eligibility criteria. The PRISMA guidelines were followed, and five studies had comparable data that were suitable for a meta-analysis. RESULTS The Cochrane Risk of Bias tool for RCTs showed low risk of bias across most domains. The pooled odds ratio showed that more patients significantly had normalized TRAb levels post-TTx as compared to other interventions (OR: 1.36, 95% CI: 1.02-1.81, p = 0.035). But, there was no significant difference in GO improvement post-TTx as compared with other intervention groups. CONCLUSIONS This meta-analysis shows that TRAb levels may decline largely post-TTx, but may not predict added improvements to the progression of GO. Thus, future studies with uniform designs are required to assess the minimal significant GO improvements.

Abstract
BACKGROUND To ensure the success of total knee arthroplasty (TKA), precise bone cuts and a well-balanced soft tissue envelope are crucial. Soft tissue release may be necessary, subject to various factors. Therefore, documenting the type, frequency, and necessity of soft tissue releases can establish a benchmark for comparing different alignment techniques and philosophies and evaluating their outcomes. The purpose of this study was to demonstrate that robotic-assisted knee surgery requires minimal soft tissue release. METHODS We prospectively documented and retrospectively reviewed the soft tissue releases employed in securing ligament balance in the first 175 patients who received robotic-assisted TKAs at Nepean Hospital. ROSA was utilized in all surgeries with the aim of restoring mechanical coronal alignment, with a flexion gap balancing technique. Surgeries were performed between December 2019 to August 2021 by a single surgeon who used a standard medial parapatellar approach without a tourniquet, and the cementless persona prosthesis. All patients were followed up for a minimum of 6 months post-surgery. Soft tissue releases included any form of medial release for varus knee, posterolateral release for valgus knee and PCL fenestration or sacrifice. RESULTS There were 131 female and 44 male patients, aged between 48 to 89 years (average 60 years). The preoperative HKA ranged from 22 degrees varus to 28 degrees valgus, with 71% of patients presenting with a varus deformity. For the whole group, the no need for soft tissue release was documented in 123 patients (70.3%), small fenestrated releases of PCL in 27 (15.4%), sacrifice of PCL in 8 (4.5%), medial releases in 4 (2.3%) and posterolateral releases in 13 (7.4%). In 29.7% of patients in whom a soft tissue release was necessary for balance, over half were/received minor fenestrations of the PCL. Outcomes to date included no revisions or impending revisions, 2 MUAs (1%), and Oxford knee scores averaged 40 at 6 months. CONCLUSION We concluded that Robot technology enhanced the precision of bone cuts and allowed for titration of required soft tissue releases to achieve optimal balance.

Abstract
Timely delivery of adjuvant chemotherapy is crucial. With an increasing frequency of immediate breast reconstructions (IBR) following mastectomy (MAS), concerns have arisen regarding its complication rates and effects on time to chemotherapy. The aim was to conduct a systematic review and meta-analysis to determine if there is a prolonged time to chemotherapy (TTC) after IBR and MAS. Electronic databases, reference lists and relevant articles were searched systematically. Eligibility criteria included women receiving adjuvant chemotherapy who underwent either MAS only or MAS and IBR. Random-effects models were used in the analysis. A total of 29 studies were included in qualitative analysis, comprising of 156,000 patients (IBR: 57,159; MAS: 98,841). But 23 studies had sufficient data to be included in the meta-analysis. Sixteen papers concluded there was no difference in TTC compared to MAS. There was a difference of 3.50 days between TTC in IBR versus MAS (95% CI [0.42, 6.57], P value = .0256; IBR = 43.56 days, MAS = 40.38 days). The rate of patients being delayed past 90 days was not significantly higher in IBR (OR = 1.34, 95% CI [0.76, 2.38], P = .310). IBR patients were more likely to have complications compared to the MAS group (OR = 2.04, 95% CI [1.04-4.01], P < .01). We concluded that there is a statistically significant longer time to chemotherapy following IBR of 3.50 days, yet there is no difference in delays past 90 days. Therefore, the longer TTC in IBR is unlikely to be of any clinical significance.
