Tendinopathy is a debilitating musculoskeletal
condition which can cause significant pain and lead to complete rupture
of the tendon, which often requires surgical repair. Due in part
to the large spectrum of tendon pathologies, these disorders continue
to be a clinical challenge. Animal models are often used in this
field of research as they offer an attractive framework to examine
the cascade of processes that occur throughout both tendon pathology and
repair. This review discusses the structural, mechanical, and biological
changes that occur throughout tendon pathology in animal models,
as well as strategies for the improvement of tendon healing. Cite this article:

Elbow Roundup360 looks at: PRP is not effective in tennis elbow; eccentric physiotherapy effective in subacromial pain; dexamethasone in shoulder surgery; arthroscopic remplissage for engaging Hill-Sach’s lesions; a consistent approach to subacromial impingement; delay in fixation of proximal humeral fractures detrimental to outcomes.
The global economy has been facing a financial crisis. Healthcare costs are spiraling, and there is a projected £30 billion health funding gap by 2020 in the UK. What is happening in the UK is a reflection of a global problem. Rationing of healthcare is a topic of much discussion; as unless spending is capped, providing healthcare will become unsustainable. Who decides how money is spent, and which services should be rationed? In this article we aim to discuss the impact that rationing may have on orthopaedic surgery, and we will discuss our own experiences of attempts to ration local services.
The reported prevalence of an asymptomatic slip
of the contralateral hip in patients operated on for unilateral slipped
capital femoral epiphysis (SCFE) is as high as 40%. Based on a population-based
cohort of 2072 healthy adolescents (58% women) we report on radiological
and clinical findings suggestive of a possible previous SCFE. Common
threshold values for Southwick’s lateral head–shaft angle (≥ 13°)
and Murray’s tilt index (≥ 1.35) were used. New reference intervals
for these measurements at skeletal maturity are also presented. At follow-up the mean age of the patients was 18.6 years (17.2
to 20.1). All answered two questionnaires, had a clinical examination
and two hip radiographs. There was an association between a high head–shaft angle and
clinical findings associated with SCFE, such as reduced internal
rotation and increased external rotation. Also, 6.6% of the cohort
had Southwick’s lateral head–shaft angle ≥ 13°, suggestive of a
possible slip. Murray’s tilt index ≥ 1.35 was demonstrated in 13.1%
of the cohort, predominantly in men, in whom this finding was associated
with other radiological findings such as pistol-grip deformity or
focal prominence of the femoral neck, but no clinical findings suggestive
of SCFE. This study indicates that 6.6% of young adults have radiological
findings consistent with a prior SCFE, which seems to be more common
than previously reported. Cite this article:

The aim of this study was to examine the functional
outcome at ten years following lateral closing wedge high tibial osteotomy
for medial compartment osteoarthritis of the knee and to define
pre-operative predictors of survival and determinants of functional
outcome. 164 consecutive patients underwent high tibial osteotomy between
2000 and 2002. A total of 100 patients (100 knees) met the inclusion
criteria and 95 were available for review at ten years. Data were
collected prospectively and included patient demographics, surgical
details, long leg alignment radiographs, Western Ontario and McMaster Universities
osteoarthritis index (WOMAC) and Knee Society scores (KSS) pre-operatively
and at five and ten years follow-up. At ten years, 21 patients had been revised at a mean of five
years. Overall Kaplan–Meier survival was 87% (95% confidence interval
(CI) 81 to 94) and 79% (95% CI 71 to 87) at five and ten years,
respectively. When compared with unrevised patients, those who had
been revised had significantly lower mean pre-operative WOMAC Scores
(47 (21 to 85) This study has shown that improved survival is associated with
age <
55 years, pre-operative WOMAC scores >
45 and, a BMI <
30. In patients over 55 years of age with adequate pre-operative
functional scores, survival can be good and functional outcomes
can be significantly better than their younger counterparts. We
recommend the routine use of pre-operative functional outcome scores
to guide decision-making when considering suitability for high tibial osteotomy. Cite this article:

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
A pragmatic multicentre randomised controlled trial (PROFHER)
was conducted in United Kingdom National Health Service (NHS) hospitals
to evaluate the clinical effectiveness and cost effectiveness of
surgery compared with non-surgical treatment for displaced fractures
of the proximal humerus involving the surgical neck in adults. A cost utility analysis from the NHS perspective was performed.
Differences between surgical and non-surgical treatment groups in
costs and quality adjusted life years (QALYs) at two years were
used to derive an estimate of the cost effectiveness of surgery
using regression methods. Aims
Methods
Bariatric surgery has been advocated as a means
of reducing body mass index (BMI) and the risks associated with total
knee arthroplasty (TKA). However, this has not been proved clinically.
In order to determine the impact of bariatric surgery on the outcome
of TKA, we identified a cohort of 91 TKAs that were performed in
patients who had undergone bariatric surgery (bariatric cohort).
These were matched with two separate cohorts of patients who had not
undergone bariatric surgery. One was matched 1:1 with those with
a higher pre-bariatric BMI (high BMI group), and the other was matched
1:2 based on those with a lower pre-TKA BMI (low BMI group). In the bariatric group, the mean BMI before bariatric surgery
was 51.1 kg/m2 (37 to 72), which improved to 37.3 kg/m2 (24
to 59) at the time of TKA. Patients in the bariatric group had a
higher risk of, and worse survival free of, re-operation (hazard
ratio (HR) 2.6; 95% confidence interval (CI) 1.2 to 6.2; p = 0.02)
compared with the high BMI group. Furthermore, the bariatric group
had a higher risk of, and worse survival free of re-operation (HR
2.4; 95% CI 1.2 to 3.3; p = 0.2) and revision (HR 2.2; 95% CI 1.1
to 6.5; p = 0.04) compared with the low BMI group. While bariatric surgery reduced the BMI in our patients, more
analysis is needed before recommending bariatric surgery before
TKA in obese patients. Cite this article:

The incidence of acute and chronic conditions
of the tendo Achillis appear to be increasing. Causation is multifactorial
but the role of inherited genetic elements and the influence of
environmental factors altering gene expression are increasingly
being recognised. Certain individuals’ tendons carry specific variations
of genetic sequence that may make them more susceptible to injury.
Alterations in the structure or relative amounts of the components
of tendon and fine control of activity within the extracellular
matrix affect the response of the tendon to loading with failure
in certain cases. This review summarises present knowledge of the influence of
genetic patterns on the pathology of the tendo Achillis, with a
focus on the possible biological mechanisms by which genetic factors
are involved in the aetiology of tendon pathology. Finally, we assess
potential future developments with both the opportunities and risks
that they may carry. Cite this article:
A patient-centred approach, usually achieved through shared decision
making, has the potential to help improve decision making around
knee arthroplasty surgery. However, such an approach requires an
understanding of the factors involved in patient decision making.
This review’s objective is to systematically examine the qualitative literature
surrounding patients’ decision making in knee arthroplasty. A systematic literature review using Medline and Embase was conducted
to identify qualitative studies that examined patients’ decision
making around knee arthroplasty. An aggregated account of what is
known about patients’ decision making in knee arthroplasties is
provided.Objectives
Methods
Adolescent idiopathic scoliosis affects about
3% of children. Non-operative measures are aimed at altering the natural
history to maintain the size of the curve below 40° at skeletal
maturity. The application of braces to treat spinal deformity pre-dates
the era of evidence-based medicine, and there is a paucity of irrefutable
prospective evidence in the literature to support their use and
their effectiveness has been questioned. This review considers this evidence. The weight of the evidence
is in favour of bracing over observation. The most recent literature
has moved away from addressing this question, and instead focuses
on developments in the design of braces and ways to improve compliance. Cite this article:
We explored the outcome of staged bilateral total
knee replacement (TKR) for symmetrical degenerative joint disease
and deformity in terms of patient expectations, functional outcome
and satisfaction. From 2009 to 2011, 70 consecutive patients (41
female) with a mean age of 71.7 years (43 to 89) underwent 140 staged
bilateral TKRs at our institution, with a mean time between operations
of 7.8 months (2 to 25). Patients were assessed pre-operatively
and at six and 12 months post-operatively using the Short Form-12,
Oxford knee score (OKS), expectation questionnaire and satisfaction
score. The pre-operative OKS was significantly worse before the
first TKR (TKR1), but displayed significantly greater improvement
than that observed after the second TKR (TKR2). Expectation level
increased from TKR1 to TKR2 in 17% and decreased in 20%. Expectations
of pain relief and stair-climbing were less before TKR2; in contrast,
expectations of sporting and social activities were greater. Decreased expectations
of TKR2 were significantly associated with younger age and high
expectations before TKR1. Patient satisfaction was high for both
TKR1 (93%) and TKR2 (87%) but did not correlate significantly within
individuals. We concluded that satisfaction with one TKR does not
necessarily translate to satisfaction following the second. Cite this article:
This study compared the clinical outcomes following
mini-open rotator cuff repair (MORCR) between early mobilisation
and usual care, involving initial immobilisation. In total, 189
patients with radiologically-confirmed full-thickness rotator cuff
tears underwent MORCR and were randomised to either early mobilisation
(n = 97) or standard rehabilitation (n = 92) groups. Patients were
assessed at six weeks and three, six, 12 and 24 months post-operatively.
Six-week range of movement comparisons demonstrated significantly
increased abduction (p = 0.002) and scapular plane elevation (p
= 0.006) in the early mobilisation group, an effect which was not
detectable at three months (p >
0.51) or afterwards. At 24 months
post-operatively, patients who performed pain-free, early active mobilisation
for activities of daily living showed no difference in clinical
outcomes from patients immobilised for six weeks following MORCR.
We suggest that the choice of rehabilitation regime following MORCR
may be left to the discretion of the patient and the treating surgeon. Cite this article:
