Robotic-Assisted Patellofemoral Replacement-Correlation of Preoperative Planning with Intraoperative Implant Position and Early Clinical Experience: A Minimum 2-Year Follow-up.

Patello-femoral arthroplasty (PFA) is successful in a selected group of patients and yields a good functional outcome. Robotic-assisted knee arthroplasty has been shown to provide better implant positioning and alignment. We aim to report our early outcomes and to compare Mako's (Robotic Arm Interactive Orthopaedic System [RIO]) preoperative implant planning position to our intraoperative PFA implant position.

A Randomised Controlled Trial of Local Infiltration Analgesia Versus Femoral Nerve Block for Postoperative Analgesia Following Total Knee Arthroplasty.

Background Total knee replacement is often associated with significant postoperative pain. Although the use of a femoral nerve block is well-established, local infiltration analgesia has gained popularity in recent years. We compared single-shot local infiltration analgesia with a single-shot femoral nerve block for patients undergoing primary total knee arthroplasty.

Periprosthetic fractures in the distal femur following total knee replacement: A review and guide to management.

The management of distal femoral fractures following a total knee replacement can be complex and requires the equipment, perioperative support and surgical skills of both trauma and revision arthroplasty services. Recent advances in implant technology have changed the management options of these difficult fractures. This article describes the options available and discusses the latest evidence.

The use of radiofrequency energy for arthroscopic chondroplasty in the knee.

We present a review of the current literature surrounding the use of radiofrequency energy for arthroscopic chondroplasty in the knee. This review article summarizes basic science, clinical efficacy, and recent advances in the understanding of radiofrequency energy use for the treatment of chondral lesions. Laboratory evidence of increased mechanical stability and decreased release of inflammatory mediators associated with the use of radiofrequency energy chondroplasty is described with clinical evidence of decreased pain and increased functional scores when compared with mechanical chondroplasty.

The value of magnetic resonance imaging in investigating a painful total knee arthroplasty.

This case describes a rare cause of pain around a total knee arthroplasty and highlights the importance of a structured approach to the investigation of these patients. Magnetic resonance imaging provided detailed information about the cause of pain despite the presence of a prosthetic joint, and the pathology, primary non-Hodgkin lymphoma, was treated without the need for further surgical intervention.

Pasteurella abscess in tibial regenerate bone: a case report.

Although superficial pin tract infections during limb lengthening are extremely common, most settle spontaneously or with antibiotics. In contrast, deep infection around pin tracts leading to osteomyelitis and abscess formation is much less frequently observed and may need washout and curettage. We report a case of a 10-year-old boy who presented with latent abscess formation at a tibial lengthening site because of Pasteurella, a rare bacterial cause of infection usually associated with animals.

Hyponatraemia after orthopaedic surgery - a case of pituitary apoplexy.

We describe a case of profound hyponatraemia in a postoperative patient after total hip replacement caused by corticosteroid insufficiency due to a non-functioning pituitary macroadenoma diagnosed by dynamic endocrine tests and radiological imaging. Adopting a multidisciplinary approach, successful diagnosis and management lead to a complete recovery without any long-term sequelae.
