Anatomical total knee arthroplasty alignment versus conventional mechanical alignment; or a combination?

This paper aims to provide evidence-based guidance for the general orthopaedic surgeon faced with the presentation of a potential soft tissue sarcoma in an extremity.

Ankle replacements have improved significantly since the first reported attempt at resurfacing of the talar dome in 1962. We are now at a stage where ankle replacement offers a viable option in the treatment of end-stage ankle arthritis. As the procedure becomes more successful, it is important to reflect and review the current surgical outcomes. This allows us to guide our patients in the treatment of end-stage ankle arthritis. What is the better surgical treatment – arthrodesis or replacement?

Not all questions can be answered by prospective randomised controlled trials. Registries were introduced as a way of collecting information on joint replacements at a population level. They have helped to identify failing implants and the data have also been used to monitor the performance of individual surgeons. This review aims to look at some of the less well known registries that are currently being used worldwide, including those kept on knee ligaments, ankle arthroplasty, fractures and trauma.

In the UK we have many surgeon inventors – surgeons who innovate and create new ways of doing things, who invent operations, who design new instruments to facilitate surgery or design new implants for using in patients. However truly successful surgeon inventors are a rare breed and they need to develop additional knowledge and skills during their career in order to push forward their devices and innovations. This article reviews my own experiences as a surgeon inventor and the highs and lows over the whole of my surgical career.

Modern athletes are constantly susceptible to performance-threatening injury as they push their bodies to greater limits and endure higher physical stresses. Loss of performance and training time can adversely and permanently affect a sportsperson’s career. Now more than ever with advancing medical technology the answer may lie in biologic therapy. We have been using peripheral blood stem cells (PBSC) clinically and have been able to demonstrate that stem cells differentiate into target cells to enable regenerative repair. The potential of this technique as a regenerative agent can be seen in three broad applications: 1) articular cartilage, 2) bone and 3) soft tissue. This article highlights the successful cases, among many, in all three of these applications.

A comprehensive study of osteology remains a cornerstone of current orthopaedic and traumatological education. Osteology was already established as an important part of surgical education by the 16^th century. In order to teach anatomy and osteology, the corpses of executed criminals were dissected by the praelector anatomiae of the Amsterdam Guild of Surgeons. Magnificent anatomical atlases preserve the knowledge obtained from these dissections. We present an overview of the most authoritative works of Vesalius, Bidloo, Cheselden, and Albinus authored in the 16^th, 17^th and 18^th centuries. At that time a knowledge of osteology was necessary to pass the ‘master-exam’ in order to become a surgeon, and anatomical teaching was traditionally based on the practice of dissection. In the modern era, anatomical dissection and illustrations are largely being replaced by three-dimensional imaging and computer simulations, with an unfortunate trend in current curricula away from the established teaching technique of dissection. Education through the practice of dissection, particularly for future surgeons, remains integral to the development of tissue handling techniques, understanding of anatomical variation, and furthering of spatial awareness skills. With this review, we seek to remind contemporary surgeons of the lessons we can learn from our predecessors who valued education through anatomical dissection.

Amputation was once widely practised for primary bone tumours of the limbs. Yet this situation has changed with limb salvage surgery becoming increasingly popular in the last 30 years. Many different techniques are now available. These include allografts, autografts, endoprostheses and allograft-prosthesis composites. This article reviews these methods, concentrating on the functional outcomes and complications that have been reported.

Chris Lavy is an orthopaedic surgeon in Oxford (UK) who lived and worked in Malawi for ten years. There he helped build an orthopaedic hospital and research unit. He was also one of the founders of COSECSA, the regional college of surgeons for East and Central Africa in 1999.
