Abstract

Objectives

To analyse the costs and benefits of sending femoral head specimens for histopathological analysis and whether our practice had changed since the original study five years ago.

Methods

The cohort definition was patients who had both undergone hip hemiarthroplasties (HHAs) and had femoral head specimens sent for histopathological analysis at our tertiary care institution from 2013 to 2016. Retrospective review of clinical and electronic notes was performed on these patients for history of malignancy, histopathological diagnosis of femoral head, indication for histopathological examination and radiological studies. The total number of HHAs performed at the centre and the costs involved in analysing each femoral head specimen were identified.

Introduction

Femoroacetabular impingement (FAI) is a morphological hip joint deformity associated with pain and early degenerative changes. Cam-type FAI is prevalent in young male athletes. While biomechanical deficiencies (decreased hip muscle strength and range of motion (ROM)) have been associated with symptomatic cam-type FAI (sFAI), results have been conflicting and little is known about biomechanical characteristics during dynamic tasks.

Objectives

(1) Compare coronal-plane hip muscle strength, activation and joint rotation during movement tasks in sFAI hips against healthy controls. (2) Investigate the effect of hip internal rotation ROM (IR-ROM) on these outcomes.

Introduction

Proteomic analysis has the ability to reveal both the different types and abundances of proteins in a sample. To date, proteomic analysis has received limited attention in the field of tendon research, with mainly ex vivo investigations being undertaken to characterize the tendon proteome. A significant development would be the ability to detect in vivo changes in the proteomic composition as this could have clearer and more direct understanding on the efficiency of therapies. It is well documented that sample preparation is one of the most crucial steps in obtaining high quality resolution of proteins in mass spectrometry. Biological samples can vary in complexity, and minimization of this through sample handling and cleaning can drastically improve the resolved peptide spectra. During this investigation, samples of microdialysis media from the peritendinous space of the Achilles tendon pre or post shockwave therapy were used to establish whether the in vivo identification and quantification of proteins was possible.

Materials and Methods

Six microdialysis samples were obtained from human subjects before (controls) or after shock wave therapy on their achilles tendon. Samples were concentrated and intefering substances removed using StrataClean™ resin. Reduction, alkylation and an In-solution tryptic digestion was performed with the prior addition of 1% Rapigest SF solution. Samples were then analysed by Liquid Chromatography Mass Spectrometry/Mass Spectrometry. Data files were searched using IPI-human database using Mascot Search Engine. Relative quantification was performed between groups by ProgenesisQI.

Introduction

An additional pathology should be considered for Achillodynia differentials – the intratendinous tear (ITT) – for which we describe symptoms, ultrasound findings and co-presenting pathology.

Materials and Methods

Examinations of 740 Achillodynic patients in one specialist centre were reviewed. ITTs were defined as a clearly visualised echopoor area situated centrally and extending to, but not through the tendon periphery, with pain on palpation and no clinical findings consistent with Achilles rupture. Descriptive statistics were used to analyse differences between pathological sub-groups, and images described qualitatively.

Introduction

Numerous risk factors have been identified for patellar tendinopathy (PT), often in small population studies. The aim was to use an online questionnaire internationally to generate a large database and identify significant risk factors.

Materials and Methods

Subjects were recruited from England, Spain and Italy with the questionnaire available in all three languages, with the questionnaire previously having been validated by Morton et al. (2014) as to be suitable for self-administration. The questionnaire can be viewed at: http://patellartendinopathyquestionnaire.blogspot.co.uk/ (English), http://tendinopatiarotuliana.blogspot.co.uk/ (Spanish) and http://tendinopatiarotulea.blogspot.co.uk/ (Italian). All data was anonymised and password protected. 825 data sets were collected with 23.4% having clinically diagnosed PT.

Introduction

Achilles tendinopathy (AT) is a highly prevalent injury in athletes and non-athletes with an unknown aetiology. Genetic risk factors have been a recent focus of investigation. The aim of this systematic review was to determine which loci have been linked with mid-portion AT and could potentially be used as biomarkers in tendinopathy risk models or as preventative or therapeutic targets.

Materials and Methods

Eight electronic bibliographic databases were searched from inception to April 2015 for cross-sectional, prospective cohort and case-control studies that included empirical research investigating genes associated with mid-portion AT. Potential publications were assessed by two independent reviewers (AAC and PRJ) for inclusion and quality. Quality was evaluated using a validated scale.

Introduction

High-volume image guided injections (HVIGI) followed by structured rehabilitation have been shown to be effective in various musculoskeletal conditions including Achilles tendinopathy and shoulder impingement syndrome. The aim was to explore the effect of a HVIGI in Hoffa's fat pad impingement, a common cause of anterior knee pain.

Materials and Methods

100 consecutive subjects who received a HVIGI followed by a standardised physiotherapy rehabilitation regime for Hoffa's fat pad impingement (diagnosed using clinical history, examination and magnetic resonance imaging) at one specialist MSK centre were sent a follow-up questionnaire. The questionnaire collected demographics, symptom length and the percentage improvement in symptoms following the HVIGI. All had received HVIGI consisting of 10ml of 0.5% Marcaine and 50mg of hydrocortisone followed by a structured rehabilitation programme with a focus on lower limb alignment control, flexibility, hip and knee strengthening in line with best practice. Data was analysed using SPSS version 20 at this interim stage; data collection is continuing.

Introduction

Tendinopathies are debilitating and painful conditions. They are believed to result from repetitive overuse, which can create micro-damage that accumulates over time, and initiates a catabolic cell response. The aetiology of tendinopathy remains poorly understood, therefore the ideal treatment remains unclear. However, current data support the use of eccentric exercise as an effective treatment. In a previous study, we have shown that eccentric loading generates perturbations in the tendon at 10Hz, which is not present during other less effective loading regimes. Consequently, we hypothesis that 10Hz loading initiates an increased anabolic response in tenocytes, that can promote tendon repair.

Materials and Methods

Human tenocytes from healthy hamstring tendons and tendinopathic Achilles tendons were derived by collagenase digest and outgrowth respectively. Tenocytes were seeded into 3D collagen gels. The gels were fixed in custom-made chambers and placed in an incubator for 24hrs whilst gene expression stabilised. After 24hrs, cyclic uniaxial strain at 1% ± 1% was applied to the cells, at either 1Hz (n=4) or 10Hz (n=4) using a Bose loading system. After 15 minutes of cyclic strain, the samples were maintained in chambers under 1% static strain for 24 hrs after which gene expression was characterised using RT-PCR.

Introduction

The majority of radial head fractures may be treated successfully by conservative means and they are often considered a benign injury. However, approximately 25% of Mason type II fractures will not have a good long term result. Pain and stiffness can be a problem and this may be a significant complaint in young active patients with pain at end range of motion.

Methods

A retrospective review of a single surgeon series of 62 consecutive elbow arthroscopic arthrolyses performed in 62 patients between June 2006 and Sept 2009 was performed. Pre- and post-operative ranges of motion (ROM) were assessed and recorded along with the patient's DASH score. Patients were kept in overnight and splinted in extension. Splints were removed the following day and AROM exercises were commenced with the physiotherapist. Patients were reviewed and assessed at follow up.
