Medial congruent with posterior cruciate ligament resected achieves similar short term outcome as posterior stabilised total knee arthroplasty.

Introduction: Medial congruent (MC) systems and Posterior stabilized (PS) systems are widely utilized as implant options in total knee arthroplasties (TKAs). Nevertheless, determining which system yields superior clinical outcomes remains unresolved. This study seeks to compare these two systems by conducting a retrospective analysis of data from a single surgeon's registry encompassing both systems.

New evidence on patella resurfacing in modern total knee arthroplasty for all inflammatory arthritis in a mixed Asian population.

Background: Traditional teaching advocates for routine patella resurfacing (PR) during total knee arthroplasty (TKA) in patients with inflammatory arthritis. However, evidence on this topic remains limited in the Asian population. This study aims to evaluate the postoperative outcomes and complication of patella resurfacing (PR) during primary total knee arthroplasty (TKA) in Asian patients with inflammatory arthritis.

No difference in clinical outcomes when retaining or sacrificing the posterior cruciate ligament in medial congruent total knee replacement. A retrospective study.

Purpose: The aim of this study is to evaluate the effect of retaining or sacrificing the posterior cruciate ligament (PCL) in patients who undergo primary total knee replacement (TKR) with the medial congruent (MC) implant.

Methods: This retrospective study looks at patients who underwent TKR with the MC implant. Comparison was made between the group with the PCL sacrificed (MC-PCLS) and the group with the PCL retained (MC-PCLR).

Use of Fibrin Glue as a Surgical Adjunct in Bone Grafting of Fracture Non-unions.

Introduction: Non-union of long bones is a common challenge in the treatment of fractures. Bone grafting is commonly used to treat atrophic non-union, but mechanical displacement of the graft may occur, resulting in delay or failure of treatment. Fibrin glue has demonstrated positive results in management of bone defects in neurosurgery and oromaxillary facial surgery, however, there has yet to be any study on its use in long bone fractures.

Faster improvement in outcome scores in posterior stabilised total knee arthroplasty compared to medial congruent system with posterior cruciate ligament retained.

Most studies comparing medial pivot to the posterior stabilised (PS) systems sacrifice the PCL. It is unknown whether retaining the PCL in the Medial Congruent (MC) system may provide further benefit compared to the more commonly used PS system. A retrospective review of a single-surgeon's registry data comparing 44 PS and 26 MC with PCL retained (MC-PCLR) TKAs was performed.

Return to work following knee arthroplasty: a retrospective review in urban Asian population.

Background: An increasing number of working adults undergo knee arthroplasty in Singapore. There is limited data concerning Southeast Asian patients returning to work (RTW) following knee replacement surgery. Our aim was to identify and study factors influencing patients RTW following total knee arthroplasty (TKA) or unicompartmental knee arthroplasty (UKA).

Comparing Outcomes of Total Hip Arthroplasty for Displaced Neck of Femur Fractures in Elderly Patients Utilizing Dual Mobility Cups and Conventional Implants: A Single Center Retrospective Study of 129 Patients.

Introduction: Studies comparing the use of total hip arthroplasty (THA) with conventional implants and hemiarthroplasty for displaced femoral neck fractures (DFNF) have reported better patient satisfaction scores and outcomes in the former, but also significant dislocation rates (6.9-13%).The total hip arthroplasty with dual mobility cup (THA-DMC) design is mechanically proven to increase the hip range of motion and jump distance to dislocation relative to conventional implants.

An Orthopaedic Surgeon Led Osteoporosis (OSLO) Model of Care reduces early recurrent fracture rates and improves treatment compliance in patients treated for osteoporotic fractures.

Unlabelled: This study aims to evaluate the efficacy of an Orthopaedic Surgeon Led Osteoporosis Model of Care (OSLO-MoC) in improving care of patients with primary osteoporotic fractures. The OSLO-MOC has shown to be effective in improving osteoporotic medication initiation and compliance and reducing secondary fracture rates in patients.

Purpose: This study aims to evaluate the efficacy of an Orthopaedic Surgeon Led Osteoporosis Model of Care (OSLO-MoC) as compared to a Case Manager Led Osteoporosis Model of Care (CMLO-MoC) in reducing early osteoporotic re-fracture rates and treatment compliance in patients.

Is unicompartmental knee arthroplasty truly contraindicated in an obese patient? A meta-analysis.

Background: Obesity has long been considered a relative contraindication to unicompartmental knee arthroplasty (UKA). However, with improved implants and techniques, the criteria for UKAs have been challenged. This paper aims to assess the impact of body mass index (BMI) on revision rates and functional outcomes in UKAs.

A Simple Technique for Removal of Interlocking Screw from an Intramedullary Nail: A Case Report.

Introduction: Difficulties encountered during removal of implants present a common technical challenge in orthopedic surgery, for which a number of factors have been implicated. A variety of techniques and instruments have been used to overcome this. However, some of these may prove to be time consuming, expensive, and inaccessible to many surgical setups.

The MeNT-OS Score for Orthopaedic Surgery: An Objective Scoring System for Prioritisation of Orthopaedic Elective Surgeries During a Pandemic.

Introduction: The reintroduction of elective Orthopaedic surgery during the COVID-19 pandemic is likely to occur in phases, dictated by resource limitations and loco-regional pandemic status. Guidelines providing a general framework for the prioritisation of surgery have largely been based on surgical urgency, while scoring systems such as the MeNTS score may have limited applicability in the setting of Orthopaedic Surgery. We, therefore, propose an Orthopaedic-specific algorithm ('MeNT-OS'), based on a modification of the MeNTS scoring system, that may be used to objectively triage and prioritise Orthopaedic cases during the COVID-19 pandemic.

The COVID-19 pandemic in Singapore: what does it mean for arthroplasty?

Background and purpose - The ongoing Coronavirus Disease-19 (COVID-19) pandemic has taken a toll on healthcare systems around the world. This has led to guidelines advising against elective procedures, which includes elective arthroplasty. Despite arthroplasty being an elective procedure, some arthroplasties are arguably essential, as pain or functional impairment maybe devastating for patients, especially during this difficult period.

Time-sensitive ambulatory orthopaedic soft-tissue surgery paradigms during the COVID-19 pandemic.

Purpose: Timing of surgery for orthopaedic injuries continues to evolve, as an improved understanding of biology, healing, and technological advances continues to challenge historical norms. With the growing COVID-19 pandemic stretching limited healthcare resources, postponing surgery becomes an inevitable and unenviable task for most orthopaedic surgeons, and a shift in outpatient paradigms is required to mitigate poor outcomes in patients.

Methods: A scoping review of five databases on surgical timing and orthopaedic soft-tissue injuries was performed.
