Knee arthroscopy can be used for ligamentous repair, reconstruction and to reduce burden of infection. Understanding and feeling confident with knee arthroscopy is therefore a highly important skillset for the orthopaedic surgeon. However, with limited training or experience, furthered by reduced practical education due to COVID-19, this skill can be under-developed amongst trainee surgeons. At a single institution, ten junior doctors (FY1 to CT2), were recruited as a part of a five, two-hour session, training programme utilising the Simbionix® ARTHRO Mentor knee arthroscopy simulator, supplemented alongside educational guidance with a consultant orthopaedic knee surgeon. All students had minimal to no levels of prior arthroscopic experience. Exercises completed included maintaining steadiness, image centering and orientation, probe triangulation, arthroscopic knee examination, removal of loose bodies, and meniscectomy. Pre and post-experience questionnaires and quantitative repeat analysis on simulation exercises were undertaken to identify levels of improvement.Abstract
Introduction
Methods
Tibial tubercle osteotomy (TTO) is a complex surgical procedure with a significant risk of complications, which include nonunion and tibial fracture. To determine whether an additional suture tape augmentation can provide better biomechanical stability compared with standard screw fixation. Five matched pairs of human cadaveric knees were divided into 2 groups: the first group underwent standard TTO fixation with 2 parallel screws. The second group underwent a novel fixation technique, in which a nonabsorbable suture tape (FiberTape) in a figure-of-8 construct was added to the standard screw fixation. Tubercular fragment migration of >50% of the initial distalization length was defined as clinical failure Tubercular fragment displacement during cyclic loading and pull-to-failure force were recorded and compared between the 2 groups.Abstract
Introduction
Methods
The aim of this study was to compare the short-term and mid-term outcome of lateral UKRs using a single prosthesis, the AMC Uniglide knee implant. Between 2003 and 2010, seventy lateral unicompartmental knee replacements (mean patient age 63.6±12.7 years) were performed at our unit for isolated lateral compartmental disease. Range of knee motion and functional outcome measures including the American Knee Society (AKSS), Oxford (OKS) and WOMAC scores were recorded from 19 knees at five years' post-operatively and compared to 35 knees at two-years and 53 knees at one-year post-op.Purpose
Methods
Kneeling ability is better in unicompartmental than total knee arthroplasty. There is also an impression that mobile bearing knees achieve better functional outcome than their fixed bearing cousins in unicompartmental and to a lesser extent total joint arthroplasty. In the UK, the market leading unicompartmental replacement is mobile bearing. To analyse kneeling ability after total and unicompartmental knee replacement using mobile and fixed bearing inserts.Introduction
Aim
Trochlear dysplasia (TD) is still poorly recognised, generally considered uncommon and to present purely as persistent patella dislocation. 87 patients diagnosed as having TD by a true lateral X-ray, MRI scan or at surgery were sent a questionnaire about their initial symptoms. 60% had suffered adolescent anterior knee pain. Lack of trust, wobbling, stair problems, giving way and catching were also common symptoms. Only 66% had ever suffered a dislocation, their troubles had started at 12 years of age. Most had undergone unsuccessful realignment procedures and many had developed premature lateral patello-femoral arthritis.Introduction
