Background Like with all cancers, multidisciplinary team (MDT) meetings are the norm in bone and soft tissue tumour (BST) management too. Problem in attendance of specialists due to geographical location is the one of the key barriers to effective functioning of MDTs. To overcome this problem, virtual MDTs involving videoconferencing or telemedicine have been proposed, but however this has been seldom used and tested. The COVID-19 pandemic forced the implementation of virtual MDTs in the Oxford sarcoma service in order to maintain normal service provision. We conducted a survey among the participants to evaluate its efficacy. Methods An online questionnaire comprising of 24 questions organised into 4 sections was circulated among all participants of the MDT after completion of 8 virtual MDTs. Opinions were sought comparing virtual MDTs to the conventional face-to-face MDTs on various aspects. A total of 36 responses were received and were evaluated. Results 72.8% were satisfied with the depth of discussion in virtual MDTs and 83.3% felt that the decision-making in diagnosis had not changed following the switch from face-to-face MDTs. About 86% reported to have all essential patient data was available to make decisions and 88.9% were satisfied with the time for discussion of patient issues over virtual platform. Three-fourths of the participants were satisfied (36.1% - highly satisfied; 38.9% - moderately satisfied) with virtual MDTs and 55.6% of them were happy to attend MDTs only by the virtual platform in the future. Regarding future, 77.8% of the participants opined that virtual MDTs would be the future of cancer care and an overwhelming majority (91.7%) felt that the present exercise would serve as a precursor to global MDTs involving specialists from abroad in the future. Conclusion Our study shows that the forced switch to virtual MDTs in sarcoma care following the unprecedented COVID-19 pandemic to be a viable and effective alternative to conventional face-to-face MDTs. With effective and efficient software in place, virtual MDTs would also facilitate in forming extended MDTs in seeking opinions on complex cases from specialists abroad and can expand cancer care globally.

Purpose of the study To evaluate the outcomes and complications using cemented megaprosthesis in elderly patients with distal femur nonunions (DFN). Materials and methods Between 2012 and 2016, 24 patients of DFN with an average age of 71.8 years (66-83) and an average 1.9(1-3) prior surgery was managed with distal femur replacement using cemented modular endoprosthesis. Outcomes were analysed on the following criteria: implant status, complications, knee range of motion, Knee Society Score (KSS) and Musculoskeletal Tumor Society (MSTS) score. Results All patients were extremely satisfied with their outcomes. At an average 22.1 months (10-43) follow-up, patients had an average 69.5°(40°-110°) knee flexion, an average KSS of 75.7 (63-88) and an average MSTS score of 19.3 (17-25). Four patients died at an average 21.3 months after surgery due to causes unrelated to the fracture. One patient (4.1%) had implantrelated complication; deep infection which required debridement and intravenous antibiotics. There were no late amputations or peri-operative deaths and no patient had aseptic loosening of components. Conclusion By permitting immediate full weight-bearing ambulation and with most patients returning to an acceptable functional status, cemented megaprosthesis is a viable and useful single-stage management option in elderly patients with DFN.

Purpose Osteoarthritis of knees with varus deformity is associated with a compensatory valgus deformity of the hindfoot and a lateral loading foot pressure pattern. However, whether this abnormal loading pattern is corrected in total knee arthroplasty (TKA) is unclear. Methods The alignment and loading pattern of 91 consecutive patients (121 knees) undergoing TKA with pre‐operative varus more than 10° were evaluated prospectively with functional outcome scores, static conventional radiography and dynamic pedobarogaphy pre‐operatively and 1‐year post‐operatively. Outcomes assessed were Oxford Knee Scores, American Orthopaedic Foot and Ankle Scores, femorotibial mechanical angle, tibia–hindfoot angle, hindfoot valgus/varus index (VVI), foot line of pressure (LOP) laterality and peak pressure (PP) at both time points. Results Of 121 knees, 98 (81%) regained normal alignment of the knee and 114 (92%) of the hindfoot. Similarly, PP (p < 0.001), VVI (pre‐operative: − 0.29 ± 0.22, post‐operative: − 0.04 ± 0.23, p < 0.001) and LOP laterality (pre‐operative: 7% medial, post‐operative: 96% medial, p < 0.001) all medialised post‐operatively. All patients had improved functional outcomes at the knee (pre‐operative: 20 ± 2, post‐operative: 40 ± 2, p < 0.001) and ankle (pre‐operative: 59 ± 10, post‐operative: 89 ± 6, p < 0.001). Conclusion The present study shows, following the correction of knee varus with TKA, hindfoot alignment and foot loading pattern are both restored in the majority of patients. TKA offers both static and dynamic correction as seen in the hindfoot and loading pattern, respectively. Level of evidence Level III: prospective case–control study.

Purpose Deferring cancer surgery can have profound adverse effects including patient mortality. During the COVID-19 pandemic, departmental reorganisation and adherence to evolving guidelines enabled provision of uninterrupted surgical care to patients with bone and soft tissue tumours (BST) in need of surgery. We reviewed the outcomes of surgeries on BST during the first two months of the pandemic at one of the tertiary BST centres in the UK. Materials and methods Between 12 March 2020 and 12 May 2020, 56 patients of a median age of 57 years (18-87) underwent surgery across two sites: index hospital (n = 27) and COVID-free facility (n = 29). Twenty-five (44.6%) patients were above the age of 60 years and 20 (35.7%) patients were in ASA III and ASA IV category. The decision to offer surgery was made in adherence with the guidelines issued by the NHS, BOOS and BSG. Results At a minimum follow-up of 30 days post-surgery, 54 (96.4%) patients were recovering well. Thirteen patients (23.2%) had post-operative complications which included four (7.1%) patients developing pulmonary embolism. The majority of complications (12/13 = 92.7%) occurred in ASA III and IV category patients. Four (7.1%) patients contracted COVID-19, of which three required escalation of care due to pulmonary complications and two (3.6%) died. Patients < 60 years of age had significantly less complications than those > 60 years (p < 0.001). Patients operated on in the COVID-free facility had fewer complications compared with those operated on at the index hospital (p < 0.027). Conclusion In spite of the favourable results in majority of our patients, our study shows that patients with sarcoma operated at the height of the pandemic are at a risk of contracting COVID-19 and also having associated with mortality. The use of a COVIDfree facility, surgery in patients < 60 60 years and in ASA I & II category are associated with better outcomes. If a second wave occurs, a serious consideration should be given to ways of minimising the risk of contracting COVID-19 in these vulnerable patients either by using COVID-free facilities or delaying treatment until peak of infection has passed.
