The primary aim of this study was to evaluate the efficacy of distension arthrography in the treatment of adhesive capsulitis of the shoulder. The secondary aim was to assess which patient and procedural factors predicted the recurrence of symptoms after the procedure. All patients referred to our shoulder clinic over a ten-year period, between 2008 and 2018, with a clinical diagnosis of capsulitis and symptoms persisting for more than six months, were offered treatment with a distension arthrogram. All procedures were performed by one of five musculoskeletal radiologists, with a combination of steroid, local anaesthetic, and a distention volume of 10 ml, 30 ml, or 50 ml. Patient demographics, procedural details, recurrence of symptoms, and the need for further intervention were evaluated.Aims

Unicompartmental knee arthroplasty (UKA) has become a popular method of treating knee localized osteoarthritis (OA). Additionally, the posterior cruciate ligament (PCL) is essential to maintaining the physiological kinematics and functions of the knee joint. Considering these factors, the purpose of this study was to investigate the biomechanical effects on PCL-deficient knees in medial UKA. Computational simulations of five subject-specific models were performed for intact and PCL-deficient UKA with tibial slopes. Anteroposterior (AP) kinematics and contact stresses of the patellofemoral (PF) joint and the articular cartilage were evaluated under the deep-knee-bend condition.Aims

The use of platelet-rich plasma (PRP) as an adjuvant
to tissue repair is gaining favour in orthopaedic surgery. Tunnel widening
after anterior cruciate ligament (ACL) reconstruction is a recognised
phenomenon that could compromise revision surgery. The purpose of
this study was to determine whether PRP might prevent tunnel widening
in ACL reconstruction. Patients undergoing ACL reconstruction using a hamstring graft
were randomly allocated either to have PRP introduced into the tunnels
peri-operatively or not. CT scanning of the knees was carried out
on the day after surgery and at three months post-operatively and
the width of the tunnels was measured. Patients were also evaluated
clinically at three months, when laxity was also measured. Each group comprised 25 patients, and at three months post-operatively
all were pain-free with stable knees, a negative Lachman test and

This study was performed to determine whether
pure cancellous bone graft and Kirschner (K-) wire fixation were sufficient
to achieve bony union and restore alignment in scaphoid nonunion.
A total of 65 patients who underwent cancellous bone graft and K-wire
fixation were included in this study. The series included 61 men
and four women with a mean age of 34 years (15 to 72) and mean delay
to surgery of 28.7 months (3 to 240). The patients were divided
into an unstable group (A) and stable group (B) depending on the
pre-operative radiographs. Unstable nonunion was defined as a lateral
intrascaphoid angle >
45°, or a radiolunate angle >
10°. There were
34 cases in group A and 31 cases in group B. Bony union was achieved
in 30 patients (88.2%) in group A, and in 26 (83.9%) in group B
(p = 0.439). Comparison of the post-operative radiographs between
the two groups showed no significant differences in lateral intrascaphoid
angle (p = 0.657) and scaphoid length
(p = 0.670) and height (p = 0.193). The radiolunate angle was significantly

of the ankle joint. Correlation analysis was used to investigate
the association between heterotopic ossification and outcome. . No significant association was found between the formation of
heterotopic ossification and the clinical outcome. The degree of

Evaluate if treating an unstable femoral neck fracture with a locking plate and spring-loaded telescoping screw system would improve construct stability compared to gold standard treatment methods. A 31B2 Pauwels’ type III osteotomy with additional posterior wedge was cut into 30 fresh-frozen femur cadavers implanted with either: three cannulated screws in an inverted triangle configuration (CS), a sliding hip screw and anti-rotation screw (SHS), or a locking plate system with spring-loaded telescoping screws (LP). Dynamic cyclic compressive testing representative of walking with increasing weight-bearing was applied until failure was observed. Loss of fracture reduction was recorded using a high-resolution optical motion tracking system.Aims

This prospective randomised controlled double-blind
trial compared two types of PFC Sigma total knee replacement (TKR),
differing in three design features aimed at improving flexion. The
outcome of a standard fixed-bearing posterior cruciate ligament-preserving
design (FB-S) was compared with that of a high-flexion rotating-platform
posterior-stabilised design (RP-F) at one year after TKR. The study group of 77 patients with osteoarthritis of the knee
comprised 37 men and 40 women, with a mean age of 69 years (44.9
to 84.9). The patients were randomly allocated either to the FB-S
or the RP-F group and assessed pre-operatively and at one year post-operatively.
The mean post-operative non-weight-bearing flexion was 107° (95%
confidence interval (CI) 104° to 110°)) for the FB-S group and 113°
(95% CI 109° to 117°) for the RP-F group, and this difference was
statistically significant (p = 0.032). However, weight-bearing range

the hip were randomly assigned for hip resurfacing arthroplasty
(HRA) or total hip replacement (THR). Three patients assigned to HRA were converted to THR, and three
HRA patients and two THR patients were lost to follow-up. This left
a total of 34 patients (37 hips) who underwent HRA and 38 (39 hips)
who underwent THR. The mean follow-up was 59.4 months (52 to 70)
in the HRA group and 60.6 months (50 to 72) in the THR group. There was
no failure of the prosthesis in either group. Flexion of the hip
was significantly better after HRA, but there was no difference
in the mean post-operative Harris hip scores between the groups.
The mean size of the acetabular component in the HRA group was significantly
larger than in the THR group (49.5 mm vs 46.1 mm, p = 0.001). There was
no difference in the mean abduction angle of the acetabular component
between the two groups. Although the patients in this series had risk factors for failure
after HRA, such as low body weight, small femoral heads and dysplasia,
the clinical results of resurfacing in those with Crowe type I or
II hip dysplasia were satisfactory. Patients in the HRA group had

The primary aim was to assess the independent influence of coronavirus disease (COVID-19) on 30-day mortality for patients with a hip fracture. The secondary aims were to determine whether: 1) there were clinical predictors of COVID-19 status; and 2) whether social lockdown influenced the incidence and epidemiology of hip fractures. A national multicentre retrospective study was conducted of all patients presenting to six trauma centres or units with a hip fracture over a 46-day period (23 days pre- and 23 days post-lockdown). Patient demographics, type of residence, place of injury, presentation blood tests, Nottingham Hip Fracture Score, time to surgery, operation, American Society of Anesthesiologists (ASA) grade, anaesthetic, length of stay, COVID-19 status, and 30-day mortality were recorded.Aims

There is a lack of long-term data for minimally invasive acromioclavicular (AC) joint repair. Furthermore, it is not clear if good early clinical results can be maintained over time. The purpose of this study was to report long-term results of minimally invasive AC joint reconstruction (MINAR) and compare it to corresponding short-term data. We assessed patients with a follow-up of at least five years after minimally invasive flip-button repair for high-grade AC joint dislocation. The clinical outcome was evaluated using the Constant score and a questionnaire. Ultrasound determined the coracoclavicular (CC) distance. Results of the current follow-up were compared to the short-term results of the same cohort.Aims

Kashin-Beck disease (KBD) is a kind of chronic osteochondropathy, thought to be caused by environmental risk factors such as T-2 toxin. However, the exact aetiology of KBD remains unclear. In this study, we explored the functional relevance and biological mechanism of cartilage oligosaccharide matrix protein (COMP) in the articular cartilage damage of KBD. The articular cartilage specimens were collected from five KBD patients and five control subjects for cell culture. The messenger RNA (mRNA) and protein expression levels were detected by quantitative reverse transcription PCR (qRT-PCR) and western blot. The survival rate of C28/I2 chondrocyte cell line was detected by MTT assay after T-2 toxin intervention. The cell viability and mRNA expression levels of apoptosis related genes between Aims

Our objective is to describe our early and mid-term results with the use of a new simple primary knee prosthesis as an articulating spacer in planned two-stage management for infected knee arthroplasty. As a second objective, we compared outcomes between the group with a retained first stage and those with a complete two-stage revision. We included 47 patients (48 knees) with positive criteria for infection, with a minimum two-year follow-up, in which a two-stage approach with an articulating spacer with new implants was used. Patients with infection control, and a stable and functional knee were allowed to retain the initial first-stage components. Outcomes recorded included: infection control rate, reoperations, final range of motion (ROM), and quality of life assessment (QoL) including Western Ontario and McMaster Universities osteoarthritis index, Knee Injury and Osteoarthritis Outcome Score, Oxford Knee Score, 12-Item Short-Form Health Survey questionnaire, and University of California Los Angeles (UCLA) activity score and satisfaction score. These outcomes were evaluated and compared to additional cohorts of patients with retained first-stage interventions and those with a complete two-stage revision. Mean follow-up was 3.7 years (2.0 to 6.5).Aims
