The John N. Insall Award: Functional versus Mechanical Alignment in Total Knee Arthroplasty: A Randomized Controlled Trial.

Introduction: Mechanically aligned (MA) total knee arthroplasty (TKA) is regarded as a gold standard; however, some patients report dissatisfaction post-surgery. Functional alignment (FA) is a potential alternative, integrating kinematic alignment (KA) principles with pre-resection bone balancing within defined boundaries. The use of FA aims to improve outcomes by restoring native joint lines and optimizing soft-tissue balance.

The Knee-Fix study: study protocol for a randomised controlled trial evaluating cemented and cementless components in total knee arthroplasty.

Background: Total knee arthroplasty (TKA) is an effective procedure for patients with a variety of knee conditions. The main cause of aseptic TKA failure is implant loosening, which has been linked to poor cement mantle quality. Cementless components were introduced to offer better longer-term biological fixation through osseointegration; however, early designs led to increased rate of revision due to a lack of initial press-fit and bony ingrowth.

A prospective randomised controlled trial of mechanical axis with soft tissue release balancing vs functional alignment with bony resection balancing in total knee replacement-a study using Stryker Mako robotic arm-assisted technology.

Background: Improving the functional outcome following total knee arthroplasty (TKA) by using different alignment techniques remains controversial. The surgical techniques and technologies used so far to obtain these alignments have all suffered from inaccuracies. The use of robotic technology to plan and execute the bony resection provides increased accuracy for these various alignment techniques and may determine which will deliver superior function.

Reconstruction of the proximal femur with a modular resection prosthesis.

Background: Various megaprostheses are currently available for reconstruction of the proximal femur after tumor resection. This study evaluates the survival and complications of a modular megaprosthesis for reconstruction of the proximal femur.

Materials And Methods: We studied the medical files of 109 tumor patients (age range 16-86 years) who underwent proximal femoral reconstruction with the MRP(®) megaprosthesis from 2002 to 2011.

Ulnar artery ischaemia following corticosteroid injection for carpal tunnel syndrome.

A 36-year-old female with known bilateral carpal tunnel syndrome was admitted to hospital and given a steroid injection on the ulnar side in her right hand. She suffered immediate ischaemia of the 3rd, 4th, and 5th fingers. Imaging showed decreased flow in the 4th and 5th phalageal arteries.
