Unicompartmental knee arthroplasty (UKA) is a potential treatment
for isolated bone on bone osteoarthritis when limited to a single
compartment. The risk for revision of UKA is three times higher
than for total knee arthroplasty (TKA). The aim of this review was
to discuss the different revision options after UKA failure. A search was performed for English language articles published
between 2006 and 2016. After reviewing titles and abstracts, 105
papers were selected for further analysis. Of these, 39 papers were
deemed to contain clinically relevant data to be included in this review.Objectives

Bisphosphonates are widely used as first-line treatment for primary and secondary prevention of fragility fractures. Whilst they have proved effective in this role, there is growing concern over their long-term use, with much evidence linking bisphosphonate-related suppression of bone remodelling to an increased risk of atypical subtrochanteric fractures of the femur (AFFs). The objective of this article is to review this evidence, while presenting the current available strategies for the management of AFFs. We present an evaluation of current literature relating to the pathogenesis and treatment of AFFs in the context of bisphosphonate use.Objectives
Methods
Pigmented villonodular synovitis (PVNS) is a
rare proliferative process of the synovium which most commonly affects
the knee and occurs in either a localised (LPVNS) or a diffuse form
(DPVNS). The effect of different methods of surgical synovectomy
and adjuvant radiotherapy on the rate of recurrence is unclear.
We conducted a systematic review and identified 35 observational
studies in English which reported the use of surgical synovectomy
to treat PVNS of the knee. A meta-analysis included 630 patients, 137 (21.8%) of whom had
a recurrence after synovectomy. For patients with DPVNS, low-quality
evidence found that the rate of recurrence was reduced by both open
synovectomy (odds ration (OR) = 0.47; 95% CI 0.25 to 0.90; p = 0.024)
and combined open and arthroscopic synovectomy (OR = 0.19, 95% CI
= 0.06 to 0.58; p = 0.003) compared with arthroscopic surgery. Very
low-quality evidence found that the rate of recurrence of DPVNS
was reduced by peri-operative radiotherapy (OR = 0.31, 95% CI 0.14
to 0.70; p = 0.01). Very low-quality evidence suggested that the
rate of recurrence of LPVNS was not related to the surgical approach. This meta-analysis suggests that open synovectomy or synovectomy
combined with peri-operative radiotherapy for DPVNS is associated
with a reduced rate of recurrence. Large long-term prospective multicentre
observational studies, with a focus on both rate of recurrence and
function, are required to confirm these findings. Cite this article:
The purpose of our study is to summarise the current scientific
findings regarding the impact of obesity on total hip arthroplasty
(THA); specifically the influence of obesity on the timing of THA,
incidence of complications, and effect on clinical and functional
outcomes. We performed a systematic review that was compliant with the
Preferred Reporting Items for Systematic Reviews and Meta-Analyses
guidelines to identify prospective studies from the PubMed/Medline,
Embase, and Cochrane Library databases that evaluated primary THA
in obese (body mass index (BMI) ≥ 30 kg/m2) patients.Aims
Materials and Methods
Our aim was to prepare a systematic review and meta-analysis
to compare the outcomes of cemented and cementless hemiarthroplasty
of the hip, in elderly patients with a fracture of the femoral neck,
to investigate the mortality, complications, length of stay in hospital,
blood loss, operating time and functional results. A systematic review and meta-analysis was conducted following
the Preferred Reporting Items for Systematic Reviews and Meta-Analyses
guidelines on randomised controlled trials (RCTs), studying current
generation designs of stem only. The synthesis of results was done
of pooled data, with a fixed effects or random effects model, based on
heterogeneity.Aims
Materials and Methods
We performed a systematic review of the current literature regarding
the outcomes of unconstrained metacarpophalangeal joint (MCPJ) arthroplasty. We initially identified 1305 studies, and 406 were found to be
duplicates. After exclusion criteria were applied, seven studies
were included. Outcomes extracted included pre- and post-operative
pain visual analogue scores, range of movement (ROM), strength of
pinch and grip, satisfaction and patient reported outcome measures
(PROMs). Clinical and radiological complications were recorded.
The results are presented in three groups based on the design of
the arthroplasty and the aetiology (pyrocarbon-osteoarthritis (pyro-OA),
pyrocarbon-inflammatory arthritis (pyro-IA), metal-on-polyethylene
(MoP)).Aims
Materials and Methods
The aim of this consensus was to develop a definition of post-operative
fibrosis of the knee. An international panel of experts took part in a formal consensus
process composed of a discussion phase and three Delphi rounds.Aims
Patients and Methods
Periprosthetic femoral fractures (PFF) following total hip arthroplasty
(THA) are devastating complications that are associated with functional
limitations and increased overall mortality. Although cementless
implants have been associated with an increased risk of PFF, the
precise contribution of implant geometry and design on the risk
of both intra-operative and post-operative PFF remains poorly investigated.
A systematic review was performed to aggregate all of the PFF literature
with specific attention to the femoral implant used. A systematic search strategy of several journal databases and
recent proceedings from the American Academy of Orthopaedic Surgeons
was performed. Clinical articles were included for analysis if sufficient
implant description was provided. All articles were reviewed by
two reviewers. A review of fundamental investigations of implant
load-to-failure was performed, with the intent of identifying similar
conclusions from the clinical and fundamental literature.Aims
Patients and Methods
There is uncertainty regarding the optimal means of thromboprophylaxis
following total hip and knee arthroplasty (THA, TKA). This systematic
review presents the evidence for acetylsalicylic acid (aspirin)
as a thromboprophylactic agent in THA and TKA and compares it with
other chemoprophylactic agents. A search of literature published between 2004 and 2014 was performed
in accordance with Preferred Reporting Items for Systematic Reviews
and Meta-Analyses guidelines. A total of 13 studies were eligible
for inclusion.Aims
Materials and Methods
Flail chest from a blunt injury to the thorax is associated with
significant morbidity and mortality. Its management globally is
predominantly non-operative; however, there are an increasing number
of centres which undertake surgical stabilisation. The aim of this
meta-analysis was to compare the efficacy of this approach with
that of non-operative management. A systematic search of the literature was carried out to identify
randomised controlled trials (RCTs) which compared the clinical
outcome of patients with a traumatic flail chest treated by surgical
stabilisation of any kind with that of non-operative management.Aims
Patients and Methods
Patients with osteoarthritis of the knee commonly have degenerative
meniscal tears. Arthroscopic meniscectomy is frequently performed,
although the benefits are debatable. Recent studies have concluded
that there is no role for arthroscopic washout in osteoarthritis
of the knee. Our aim was to perform a systematic review to assess
the evidence for the efficacy of arthroscopic meniscectomy in patients
with meniscal tears and degenerative changes in the knee. A literature search was performed, using the PubMed/MEDLINE database,
for relevant articles published between 1975 and 2015. A total of
six studies, including five randomised controlled trials and one
cross-sectional study of a prospective cohort, met the inclusion
criteria. Relevant information including study design, operations,
the characteristics of the patients, outcomes, adverse events and
further operations were extracted.Aims
Patients and Methods
We performed a systematic review of the literature
pertaining to the functional outcomes of the surgical management
of acetabular fractures. A total of 69 articles met our inclusion
criteria, revealing that eight generic outcome instruments were
used, along with five specific instruments. The majority of studies
reported outcomes using a version of the d’Aubigne and Postel score,
which has not been validated for use in acetabular fracture. Few validated
outcome measures were reported. No psychometric testing of outcome
instruments was performed. The current assessment of outcomes in
surgery for acetabular fractures lacks scientific rigour, and does
not give reliable outcome data for either scientific comparison
or patient counselling. Take home message: The use of non-validated functional outcome
measures is a major limitation of the current literature pertaining
to surgical management of acetabular fractures; future studies should
use validated outcome measures to ensure the legitimacy of the reported
results. Cite this article:
A variety of operative techniques have been described as under
the term ‘Bristow-Latarjet’ procedure. This review aims to define
the original procedure, and compare the variation in techniques
described in the literature, assessing any effect on clinical outcomes. A systematic review of 24 studies was performed to compare specific
steps of the technique (coracoid osteotomy site, subscapularis approach,
orientation and position of coracoid graft fixation and fixation
method, additional labral and capsular repair) and detect any effect
this variability had on outcomes.Objectives
Materials and Methods
Using a systematic review, we investigated whether there is an
increased risk of post-operative infection in patients who have
received an intra-articular corticosteroid injection to the hip
for osteoarthritis prior to total hip arthroplasty (THA). Studies dealing with an intra-articular corticosteroid injection
to the hip and infection following subsequent THA were identified
from databases for the period between 1990 to 2013. Retrieved articles
were independently assessed for their methodological quality.Aims
Methods
To examine the rates of hamstring graft salvage with arthroscopic
debridement of infected anterior cruciate ligament (ACL) reconstruction
as reported in the literature and discuss functional outcomes. A search was performed without language restriction on PubMed,
EMBASE, Ovid, CINAHL and Cochrane Register of Controlled Trials
(CENTRAL) databases from their inception to April 2015. We identified
147 infected hamstring grafts across 16 included studies. Meta-analysis
was performed using a random-effects model to estimate the overall
graft salvage rate, incorporating two different definitions of graft
salvage.Aims

To date, there is insufficient evidence available to compare
the outcome of cemented and uncemented fixation of the humeral stem
in reverse shoulder arthroplasty (RSA). A systemic review comprising 41 clinical studies was performed
to compare the functional outcome and rate of complications of cemented
and uncemented stems in RSA. These included 1455 cemented and 329
uncemented shoulders. The clinical characteristics of the two groups
were similar. Variables were compared using pooled frequency-weighted means
and relative risk ratios (RR).Aims
Methods
Vascular injuries during total hip arthroplasty
(THA) are rare but when they occur, have serious consequences. These have
traditionally been managed with open exploration and repair, but
more recently there has been a trend towards percutaneous endovascular
management. We performed a systematic review of the literature to assess
if this change in trend has led to an improvement in the overall
reported rates of morbidity and mortality during the last 22 years
in comparison with the reviews of the literature published previously. We found a total of 61 articles describing 138 vascular injuries
in 124 patients. Injuries because of a laceration were the most
prevalent (n = 51, 44%) and the most common presenting feature,
when recorded, was bleeding (n = 41, 53.3%). Delay in diagnosis
was associated with the type of vascular lesion (p <
0.001) and
the clinical presentation (p = 0.002). Open exploration and repair was the most common form of management,
however percutaneous endovascular intervention was used in one third
of the injuries and more constantly during the last 13 years. The main overall reported complications included death (n = 9,
7.3%), amputation (n = 2, 1.6%), and persistent ischaemia (n = 9,
7.3%). When compared with previous reviews there was a similar rate
of mortality but lower rates of amputation and permanent disability,
especially in patients managed by endovascular strategies. Cite this article:
The number of arthroplasties being undertaken
is expected to grow year on year, and periprosthetic joint infections will
be an increasing socioeconomic burden. The challenge to prevent
and eradicate these infections has resulted in the emergence of
several new strategies, which are discussed in this review. Cite this article:
The aim of this study was to determine whether
obesity affects pain, surgical and functional outcomes following lumbar
spinal fusion for low back pain (LBP). A systematic literature review and meta-analysis was made of
those studies that compared the outcome of lumbar spinal fusion
for LBP in obese and non-obese patients. A total of 17 studies were
included in the meta-analysis. There was no difference in the pain
and functional outcomes. Lumbar spinal fusion in the obese patient resulted
in a statistically significantly greater intra-operative blood loss
(weighted mean difference: 54.04 ml; 95% confidence interval (CI)
15.08 to 93.00; n = 112; p = 0.007) more complications (odds ratio:
1.91; 95% CI 1.68 to 2.18; n = 43858; p <
0.001) and longer duration
of surgery (25.75 mins; 95% CI 15.61 to 35.90; n = 258; p <
0.001). Obese
patients have greater intra-operative blood loss, more complications
and longer duration of surgery but pain and functional outcome are
similar to non-obese patients. Based on these results, obesity is
not a contraindication to lumbar spinal fusion. Cite this article:
