In this study, we compared the pain behaviour and osteoarthritis (OA) progression between anterior cruciate ligament transection (ACLT) and osteochondral injury in surgically-induced OA rat models. OA was induced in the knee joints of male Wistar rats using transection of the ACL or induction of osteochondral injury. Changes in the percentage of high limb weight distribution (%HLWD) on the operated hind limb were used to determine the pain behaviour in these models. The development of OA was assessed and compared using a histological evaluation based on the Osteoarthritis Research Society International (OARSI) cartilage OA histopathology score.Objectives
Methods
Surgical site infection (SSI) is a common complication of surgery
with an incidence of about 1% in the United Kingdom. Sutures can
lead to the development of a SSI, as micro-organisms can colonize
the suture as it is implanted. Triclosan-coated sutures, being antimicrobical,
were developed to reduce the rate of SSI. Our aim was to assess
whether triclosan-coated sutures cause a reduction in SSIs following
arthroplasty of the hip and knee. This two-arm, parallel, double-blinded study involved 2546 patients
undergoing elective total hip (THA) and total knee arthroplasty
(TKA) at three hospitals. A total of 1323 were quasi-randomized
to a standard suture group, and 1223 being quasi-randomized to the
triclosan-coated suture group. The primary endpoint was the rate
of SSI at 30 days postoperatively.Aims

The aim of this study was to test the null hypothesis that there
is no difference, from the payer perspective, in the cost of treatment
of a distal radial fracture in an elderly patient, aged >
65 years,
between open reduction and internal fixation (ORIF) and closed reduction (CR). Data relating to the treatment of these injuries in the elderly
between January 2007 and December 2015 were extracted using the
Humana and Medicare Advantage Databases. The primary outcome of
interest was the cost associated with treatment. Secondary analysis included
the cost of common complications. Statistical analysis was performed
using a non-parametric Aims

After intercalary resection of a bone tumour from the femur,
reconstruction with a vascularized fibular graft (VFG) and massive
allograft is considered a reliable method of treatment. However,
little is known about the long-term outcome of this procedure. The
aims of this study were to determine whether the morbidity of this
procedure was comparable to that of other reconstructive techniques,
if it was possible to achieve a satisfactory functional result, and
whether biological reconstruction with a VFG and massive allograft
could achieve a durable, long-lasting reconstruction. A total of 23 patients with a mean age of 16 years (five to 40)
who had undergone resection of an intercalary bone tumour of the
femur and reconstruction with a VFG and allograft were reviewed
clinically and radiologically. The mean follow-up was 141 months
(24Â to 313). The mean length of the fibular graft was 18Â cm (12Â to
29). Full weight-bearing without a brace was allowed after a mean
of 13 months (seven to 26).Aims
Patients and Methods
To analyse the influence of upper extremity trauma on the long-term
outcome of polytraumatised patients. A total of 629 multiply injured patients were included in a follow-up
study at least ten years after injury (mean age 26.5 years, standard
deviation 12.4). The extent of the patients’ injury was classified
using the Injury Severity Score. Outcome was measured using the
Hannover Score for Polytrauma Outcome (HASPOC), Short Form (SF)-12, rehabilitation
duration, and employment status. Outcomes for patients with and
without a fracture of the upper extremity were compared and analysed
with regard to specific fracture regions and any additional brachial
plexus lesion.Aims
Patients and Methods
It has been suggested that the use of a pilot-hole may reduce the risk of fracture to the lateral cortex. Therefore the purpose of this study was to determine the effect of a pilot hole on the strains and occurrence of fractures at the lateral cortex during the opening of a high tibial osteotomy (HTO) and post-surgery loading. A total of 14 cadaveric tibias were randomized to either a pilot hole (n = 7) or a no-hole (n = 7) condition. Lateral cortex strains were measured while the osteotomy was opened 9 mm and secured in place with a locking plate. The tibias were then subjected to an initial 800 N load that increased by 200 N every 5000 cycles, until failure or a maximum load of 2500 N.Aim

Hindfoot arthrodesis with retrograde intramedullary nailing has
been described as a surgical strategy to reconstruct deformities
of the ankle and hindfoot in patients with Charcot arthropathy.
This study presents case series of Charcot arthropathy patients
treated with two different retrograde intramedullary straight compression
nails in order to reconstruct the hindfoot and assess the results
over a mid-term follow-up. We performed a retrospective analysis of 18 consecutive patients
and 19 operated feet with Charcot arthropathy who underwent a hindfoot
arthrodesis using a retrograde intramedullary compression nail.
Patients were ten men and eight women with a mean age of 63.43 years
(38.5 to 79.8). We report the rate of limb salvage, complications requiring
additional surgery, and fusion rate in both groups. The mean duration
of follow-up was 46.36 months (37 to 70).Aims

We present the results of correcting a double or triple curve
adolescent idiopathic scoliosis using a convex segmental pedicle
screw technique. We reviewed 191 patients with a mean age at surgery of 15 years
(11 to 23.3). Pedicle screws were placed at the convexity of each
curve. Concave screws were inserted at one or two cephalad levels
and two caudal levels. The mean operating time was 183 minutes (132
to 276) and the mean blood loss 0.22% of the total blood volume
(0.08% to 0.4%). Multimodal monitoring remained stable throughout
the operation. The mean hospital stay was 6.8 days (5 to 15).Aims
Patients and Methods
The outcome of total knee arthroplasty (TKA) is not always satisfactory.
The purpose of this study was to identify satisfaction and biomechanical
features characterising the gait of patients who had undergone TKA
with either an anatomical single radius design or a medial pivot
design. We hypothesised that the latter would provide superior function. This is a study of a subset of patients recruited into a prospective
randomised study of a single radius design Aims
Patients and Methods
Meniscal allograft transplantation is undertaken to improve pain
and function in patients with a symptomatic meniscal deficient knee
compartment. While case series have shown improvements in patient
reported outcome measures (PROMs), its efficacy has not been rigorously
evaluated. This study aimed to compare PROMs in patients having
meniscal transplantation with those having personalized physiotherapy
at 12 months. A single-centre assessor-blinded, comprehensive cohort study,
incorporating a pilot randomized controlled trial (RCT) was performed
on patients with a symptomatic compartment of the knee in which
a (sub)total meniscectomy had previously been performed. They were
randomized to be treated either with a meniscal allograft transplantation
or personalized physiotherapy, and stratified for malalignment of
the limb. They entered the preference groups if they were not willing
to be randomized. The Knee injury and Osteoarthritis Outcome Score (KOOS),
International Knee Documentation Committee (IKDC) score and Lysholm
score and complications were collected at baseline and at four,
eight and 12 months following the interventions.Aims

The aim of this independent multicentre study was to assess the
mid-term results of mobile bearing unicondylar knee arthroplasty
(UKA) for isolated lateral osteoarthritis of the knee joint. We retrospectively evaluated 363 consecutive, lateral UKAs (346
patients) performed using the Oxford domed lateral prosthesis undertaken
in three high-volume knee arthroplasty centres between 2006 and
2014. Mean age of the patients at surgery was 65 years (36 to 88)
with a mean final follow-up of 37 months (12 to 93)Aims
Patients and Methods
The objective of this study was to perform a meta-analysis of all randomised controlled trials (RCTs) comparing surgical and non-surgical management of fractures of the proximal humerus, and to determine whether further analyses based on complexity of fracture, or the type of surgical intervention, produced disparate findings on patient outcomes. A systematic review of the literature was performed identifying all RCTs that compared surgical and non-surgical management of fractures of the proximal humerus. Meta-analysis of clinical outcomes was performed where possible. Subgroup analysis based on the type of fracture, and a sensitivity analysis based on the type of surgical intervention, were also performed.Objectives
