The ROSA robotic-arm system reliably restores joint line height, patella height and posterior condylar offset in total knee arthroplasty.

Introduction: There is growing interest in the use of robotic TKA to improve accuracy of component positioning in Total Knee Arthroplasty (TKA). The aim of this study was to investigate the accuracy of implant component position using the ROSA® knee system with specific reference to Joint Line Height, Patella Height and Posterior Condylar Offset (PCO).

Methods: This was a retrospective review of a prospectively-maintained database of the initial 100 consecutive TKAs performed by a high volume surgeon using the ROSA® knee system.

Mako versus ROSA: comparing surgical accuracy in robotic total knee arthroplasty.

There is increasing adoption of robotic surgical technology in Total Knee Arthroplasty. The ROSA® knee system can be used in either image-based mode (using pre-operative calibrated radiographs) or imageless modes (using intra-operative bony registration). The Mako knee system is an image-based system (using a pre-operative CT scan).

The perceptions of clinicians using low-intensity pulsed ultrasound (LIPUS) for orthopaedic pathology: A national qualitative study.

Introduction: Low-intensity pulsed ultrasound (LIPUS) is a non-invasive treatment modality for delayed union or non-union of acute fractures. We aimed to assess the current use of LIPUS at a national level in the United Kingdom, why and how clinicians use it, what treatment protocols are followed, and what the current perceptions are on this technology.

Methodology: Using a detailed online survey compromised of 20 questions delivered to known LIPUS users, we were able to collect qualitative data on indication of use, type of machine used, personal views on the technology, frequency of usage, and treatment protocols.

Successful management of life-threatening cardiac tamponade by pericardial aspiration in a boy following blunt trauma to the chest.

A 7-year-old boy was presented with significant chest pain, reduced consciousness with haemodynamic instability following a minor blunt trauma to the chest. He was diagnosed to have a life-threatening pericardial effusion in FAST (Focused Assessment with Sonography for Trauma scan) ultrasound examination which was confirmed as haemopericardium causing cardiac tamponade in 2D echocardiogram. Emergency cardiac catheterisation ruled out active bleeding and prompt pericardiocentesis under fluoroscopy guidance rapidly restored patients' haemodynamic parameters.

Posterior stabilisation without formal debridement for the treatment of non-tuberculous pyogenic spinal infection in frail and debilitated population - A systematic review and meta-analysis.

Non-tuberculous pyogenic spinal infection (PSI) incorporates a variety of different clinical conditions. Surgical interventions may be necessary for severe cases where there is evidence of spinal instability or neurological compromise. The primary surgical procedure, for late-stage PSI, focuses on the anterior approach with aggressive debridement of the infected tissue regions.
