Background Most of the commercially available TKR implants are designed for western populations, which are known to have larger build and stature compared to Asian counterparts often leading to mismatch between resected bony surfaces and implant components. There is paucity of morphometric data of distal femur and proximal tibia in the Indian population. Thus, it becomes important to obtain anthropometric data to achieve the best stability and long-term success of implant. Materials and Methods Intraoperative morphological measurements of 100 knees (59 female and 41 males) were done using vernier calliper during TKR. The anteroposterior (AP) and mediolateral (ML) dimensions of cross-section of the femur and tibia were noted before bony resection. The aspect ratios were calculated and compared with that of implant used (DePuy, Stryker, Maxx). Results We have found that Indian males have larger dimensions of distal femur as well as proximal tibia than females. There exists some degree of mismatch in patients’ dimensions and the sizes of all the three commercially available implant system as well their aspect ratios. Conclusion Specific designing of implants with dimensions in accordance with the morphometric measurements of Indian population should be done. Also gender specific implant designing should be done.

BACKGROUND The novel corona virus pandemic has a profound impact on health services throughout the world, which reflected the changing guidelines of different health societies in different time zones. We tried first to ensure the safety of our patients and surgical staff. Patient care priorities based on strict evidence-based management of a particular case and also COVID-19-adjusted governmentimposed restriction during the crisis. We aim to study postoperative complication after arthroplasty and readmission rate and compared the same with the prepandemic era. We also address our strategies, concerns, and regulatory barriers due to government-imposed lockdown, during initial surge of pandemic and also when restrictions were lifted. This study is unique in the way that there is no such study from Bihar, a state of developing country with scarcity of specialized health services. METHODS In this prospective study done in Indira Gandhi Institute Of Medical Sciences, Patna, Bihar between 1st December 2019 to 31st January 2021 (14 months duration). We have selected a subset of those patient who were admitted for primary arthroplasty of hip during the pandemic after lock down, and compared those with patient those underwent similar operative management before the lockdown period. RESULTS There was no significant difference in postoperative complication and readmission rate when compared with the pre-pandemic era. CONCLUSIONS There is no significant increase in risks of patient as well as operating surgeon before the pandemic and during the pandemic when the elective operative procedure (arthroplasty) was allowed. Communication, precautions, and proper preoperative planning remain essential part of management at each step of treatment. By following above mentioned standard operative procedure (SOP) chances of getting infection of COVID-19 is negligible from operative work. KEYWORDS COVID 19, SARS-CoV-2, Arthroplasty, Orthopaedics

The management of infected nonunion with bone loss is always challenging. The Masquelet technique is an excellent option available for us today. However, there are few reports of its use in the paediatric age group and no reports of its use especially in infected distal radius fractures or nonunion. We report on two children with infection and significant bone loss after open fractures of the distal radius which we have treated successfully using a modified Masquelet technique.
