Aims. Rotator cuff muscle atrophy and fatty infiltration affect the clinical outcomes of rotator cuff
Aims. Rotator cuff (RC)
Objectives. Indocyanine green (ICG) fluorescence angiography is an emerging technique that can provide detailed anatomical information during surgery. The purpose of this study is to determine whether ICG fluorescence angiography can be used to evaluate the blood flow of the rotator cuff tendon in the clinical setting. Methods. Twenty-six patients were evaluated from October 2016 to December 2017. The participants were categorized into three groups based on their diagnoses: the rotator cuff
Rotator cuff tear (RCT) is the leading cause of shoulder pain, primarily associated with age-related tendon degeneration. This study aimed to elucidate the potential differential gene expressions in tendons across different age groups, and to investigate their roles in tendon degeneration. Linear regression and differential expression (DE) analyses were performed on two transcriptome profiling datasets of torn supraspinatus tendons to identify age-related genes. Subsequent functional analyses were conducted on these candidate genes to explore their potential roles in tendon ageing. Additionally, a secondary DE analysis was performed on candidate genes by comparing their expressions between lesioned and normal tendons to explore their correlations with RCTs.Aims
Methods
Rotator cuff (RC) injuries are characterized by tendon rupture, muscle atrophy, retraction, and fatty infiltration, which increase injury severity and jeopardize adequate tendon repair. Epigenetic drugs, such as histone deacetylase inhibitors (HDACis), possess the capacity to redefine the molecular signature of cells, and they may have the potential to inhibit the transformation of the fibro-adipogenic progenitors (FAPs) within the skeletal muscle into adipocyte-like cells, concurrently enhancing the myogenic potential of the satellite cells. HDACis were added to FAPs and satellite cell cultures isolated from mice. The HDACi vorinostat was additionally administered into a RC injury animal model. Histological analysis was carried out on the isolated supra- and infraspinatus muscles to assess vorinostat anti-muscle degeneration potential.Aims
Methods
An objective technological solution for tracking adherence to at-home shoulder physiotherapy is important for improving patient engagement and rehabilitation outcomes, but remains a significant challenge. The aim of this research was to evaluate performance of machine-learning (ML) methodologies for detecting and classifying inertial data collected during in-clinic and at-home shoulder physiotherapy exercise. A smartwatch was used to collect inertial data from 42 patients performing shoulder physiotherapy exercises for rotator cuff injuries in both in-clinic and at-home settings. A two-stage ML approach was used to detect out-of-distribution (OOD) data (to remove non-exercise data) and subsequently for classification of exercises. We evaluated the performance impact of grouping exercises by motion type, inclusion of non-exercise data for algorithm training, and a patient-specific approach to exercise classification. Algorithm performance was evaluated using both in-clinic and at-home data.Aims

Aims. We performed a systematic review of the literature to determine

The aim of this study was to determine whether there is any significant
difference in temporal measurements of pain, function and rates
of re-tear for arthroscopic rotator cuff repair (RCR) patients compared
with those patients undergoing open RCR. This study compared questionnaire- and clinical examination-based
outcomes over two years or longer for two series of patients who
met the inclusion criteria: 200 open RCR and 200 arthroscopic RCR
patients. All surgery was performed by a single surgeon. Objectives
Methods
The pathogenesis of rotator cuff disease (RCD) is complex and
not fully understood. This systematic review set out to summarise
the histological and molecular changes that occur throughout the
spectrum of RCD. We conducted a systematic review of the scientific literature
with specific inclusion and exclusion criteria.Introduction
Methods
To report the five-year results of a randomised controlled trial
examining the effectiveness of arthroscopic acromioplasty in the
treatment of stage II shoulder impingement syndrome. A total of 140 patients were randomly divided into two groups:
1) supervised exercise programme (n = 70, exercise group); and 2)
arthroscopic acromioplasty followed by a similar exercise programme
(n = 70, combined treatment group).Objectives
Methods
Local corticosteroid infiltration is a common practice of treatment
for lateral epicondylitis. In recent studies no statistically significant
or clinically relevant results in favour of corticosteroid injections
were found. The injection of autologous blood has been reported
to be effective for both intermediate and long-term outcomes. It
is hypothesised that blood contains growth factors, which induce
the healing cascade. A total of 60 patients were included in this prospective randomised
study: 30 patients received 2 ml autologous blood drawn from contralateral
upper limb vein + 1 ml 0.5% bupivacaine, and 30 patients received
2 ml local corticosteroid + 1 ml 0.5% bupivacaine at the lateral
epicondyle. Outcome was measured using a pain score and Nirschl
staging of lateral epicondylitis. Follow-up was continued for total
of six months, with assessment at one week, four weeks, 12 weeks
and six months.Objectives
Methods
Cadaveric models of the shoulder evaluate discrete motion segments
using the glenohumeral joint in isolation over a defined trajectory.
The aim of this study was to design, manufacture and validate a
robotic system to accurately create three-dimensional movement of
the upper body and capture it using high-speed motion cameras. In particular, we intended to use the robotic system to simulate
the normal throwing motion in an intact cadaver. The robotic system
consists of a lower frame (to move the torso) and an upper frame
(to move an arm) using seven actuators. The actuators accurately
reproduced planned trajectories. The marker setup used for motion
capture was able to determine the six degrees of freedom of all
involved joints during the planned motion of the end effector.Objectives
