We recently published a paper comparing the incidence
of adverse outcomes after unicompartmental and total knee arthroplasty
(UKA and TKA). The conclusion of this study, which was in favour
of UKA, was dismissed as “biased” in a review in Cite this article:
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
Materials and Methods
The interest in unicompartmental knee arthroplasty (UKA) for
medial osteoarthritis has increased rapidly but the long-term follow-up
of the Oxford UKAs has yet to be analysed in non-designer centres.
We have examined our ten- to 15-year clinical and radiological follow-up
data for the Oxford Phase III UKAs. Between January 1999 and January 2005 a total of 138 consecutive
Oxford Phase III arthroplasties were performed by a single surgeon
in 129 patients for medial compartment osteoarthritis (71 right
and 67 left knees, mean age 72.0 years (47 to 91), mean body mass
index 28.2 (20.7 to 52.2)). Both clinical data and radiographs were
prospectively recorded and obtained at intervals. Of the 129 patients,
32 patients (32 knees) died, ten patients (12 knees) were not able
to take part in the final clinical and radiological assessment due
to physical and mental conditions, but via telephone interview it
was confirmed that none of these ten patients (12 knees) had a revision
of the knee arthroplasty. One patient (two knees) was lost to follow-up.Aims
Patients and Methods
The high revision rates of the DePuy Articular Surface Replacement (ASR) and the DePuy ASR XL (the total hip arthroplasty (THA) version) have led to questions over the viability of metal-on-metal (MoM) hip joints. Some designs of MoM hip joint do, however, have reasonable mid-term performance when implanted in appropriate patients. Investigations into the reasons for implant failure are important to offer help with the choice of implants and direction for future implant designs. One way to assess the performance of explanted hip prostheses is to measure the wear (in terms of material loss) on the joint surfaces. In this study, a coordinate measuring machine (CMM) was used to measure the wear on five failed cementless Biomet Magnum/ReCap/ Taperloc large head MoM THAs, along with one Biomet ReCap resurfacing joint. Surface roughness measurements were also taken. The reason for revision of these implants was pain and/or adverse reaction to metal debris (ARMD) and/or elevated blood metal ion levels.Objectives
Methods
We aimed to assess the influence of ethnicity on the incidence
of heterotopic ossification (HO) after total hip arthroplasty (THA). We studied the six-month post-operative anteroposterior radiographs
of 1449 consecutive primary THAs (1324 patients) and retrospectively
graded them for the presence of HO, using the Brooker Classification. Aims
Patients and Methods
We compared the outcome of total hip arthroplasty (THA) in obese
patients who previously underwent bariatric surgery and those who
did not, in a matched cohort study. There were 47 THAs in the bariatric group (42 patients), and
94 THAs in the comparison group (92 patients). The mean age of the
patients was 57 years in both groups (24 to 79) and 57% of the patients
in both groups were women. The mean time between bariatric surgery
and THA was five years (four months to 12 years) in the bariatric group.
The mean follow-up after THA was three years (2 to 9). Aims
Patients and Methods
Patients with diabetes are at increased risk of wound complications
after open reduction and internal fixation of unstable ankle fractures.
A fibular nail avoids large surgical incisions and allows anatomical
reduction of the mortise. We retrospectively reviewed the results of fluoroscopy-guided
reduction and percutaneous fibular nail fixation for unstable Weber
type B or C fractures in 24 adult patients with type 1 or type 2
diabetes. The re-operation rate for wound dehiscence or other indications
such as amputation, mortality and functional outcomes was determined.Aims
Patients and Methods
Rates of mortality as high as 25% to 30% have been described
following fractures of the odontoid in the elderly population. The
aim of this study was to examine whether easily identifiable variables
present on admission are associated with mortality. A consecutive series of 83 elderly patients with a fracture of
the odontoid following a low-impact injury was identified retrospectively.
Data that were collected included demographics, past medical history
and the results of blood tests on admission. Radiological investigations
were used to assess the Anderson and D’Alonzo classification and
displacement of the fracture. The mean age was 82.9 years (65 to
101). Most patients (66; 79.5%) had a type 2 fracture. An associated
neurological deficit was present in 11 (13.3%). All were treated
conservatively; 80 (96.4%) with a hard collar and three (3.6%) with
halo vest immobilisation.Aims
Patients and Methods
The last decade has seen a considerable increase
in the use of in total ankle arthroplasty (TAA) to treat patients
with end-stage arthritis of the ankle. However, the longevity of
the implants is still far from that of total knee and hip arthroplasties. The aim of this review is to outline a diagnostic and treatment
algorithm for the painful TAA to be used when considering revision
surgery. Cite this article:
One method of femoral head preservation following avascular necrosis
(AVN) is core decompression and insertion of a tantalum rod. However,
there may be a high failure rate associated with this procedure.
The purpose of this study was to document the clinical and radiological
outcomes following total hip arthroplasty (THA) subsequent to failed
tantalum rod insertion. A total of 37 failed tantalum rods requiring total hip arthroplasty
were identified from a prospective database. There were 21 hips
in 21 patients (12 men and nine women, mean age 37 years, 18 to
53) meeting minimum two year clinical and radiographic follow-up
whose THAs were carried out between November 2002 and April 2013
(mean time between tantalum rod implantation and conversion to a
THA was 26 months, 6 to 72). These were matched by age and gender
to individuals (12 men, nine women, mean age 40 years, 18 to 58)
receiving THA for AVN without prior tantalum rod insertion.Aims

This study describes the Osseointegration Group of Australia’s
Accelerated Protocol two-stage strategy (OGAAP-1) for the osseointegrated
reconstruction of amputated limbs. We report clinical outcomes in 50 unilateral trans-femoral amputees
with a mean age of 49.4 years (24 to 73), with a minimum one-year
follow-up. Outcome measures included the Questionnaire for persons
with a Trans-Femoral Amputation, the health assessment questionnaire
Short-Form-36 Health Survey, the Amputation Mobility Predictor scores
presented as K-levels, 6 Minute Walk Test and timed up and go tests.
Adverse events included soft-tissue problems, infection, fractures
and failure of the implant.Aims
Patients and Methods
The annual incidence of hip fracture is 620 000 in the European Union. The cost of this clinical problem has been estimated at 1.75 million disability-adjusted life years lost, equating to 1.4% of the total healthcare burden in established market economies. Recent guidance from The National Institute for Health and Clinical Excellence (NICE) states that research into the clinical and cost effectiveness of total hip arthroplasty (THA) as a treatment for hip fracture is a priority. We asked the question: can a trial investigating THA for hip fracture currently be delivered in the NHS? We performed a contemporaneous process evaluation that provides a context for the interpretation of the findings of WHiTE Two – a randomised study of THA for hip fracture. We developed a mixed methods approach to situate the trial centre within the context of wider United Kingdom clinical practice. We focused on fidelity, implementation, acceptability and feasibility of both the trial processes and interventions to stakeholder groups, such as healthcare providers and patients.Objectives
Methods
We present the medium-term clinical results of a reverse total
shoulder arthroplasty with a trabecular metal glenoid base plate. We reviewed 125 consecutive primary reverse total shoulder arthroplasties
(RTSA) implanted in 124 patients for rotator cuff arthropathy. There
were 100 women and 24 men in the study group with a mean age of
76 years (58 to 89). The mean follow-up was 32 months (24 to 60).
No patient was lost to follow-up.Aim
Patients and Methods
The aims of our study were to provide long-term information on
the behaviour of the thoracolumbar/lumbar (TL/L) curve after thoracic
anterior correction and fusion (ASF) and to determine the impact
of ASF on pulmonary function. A total of 41 patients (four males, 37 females) with main thoracic
(MT) adolescent idiopathic scoliosis (AIS) treated with ASF were
included. Mean age at surgery was 15.2 years (11 to 27). Mean follow-up
period was 13.5 years (10 to 18).Aims
Patients and Methods
Injuries to the foot in athletes are often subtle
and can lead to a substantial loss of function if not diagnosed
and treated appropriately. For these injuries in general, even after
a diagnosis is made, treatment options are controversial and become
even more so in high level athletes where limiting the time away
from training and competition is a significant consideration. In this review, we cover some of the common and important sporting
injuries affecting the foot including updates on their management
and outcomes. Cite this article:
Chronic osteomyelitis may recur if dead space management, after
excision of infected bone, is inadequate. This study describes the
results of a strategy for the management of deep bone infection
and evaluates a new antibiotic-loaded biocomposite in the eradication
of infection from bone defects. We report a prospective study of 100 patients with chronic osteomyelitis,
in 105 bones. Osteomyelitis followed injury or surgery in 81 patients.
Nine had concomitant septic arthritis. 80 patients had comorbidities
(Cierny-Mader (C-M) Class B hosts). Ten had infected nonunions. All patients were treated by a multidisciplinary team with a
single-stage protocol including debridement, multiple sampling,
culture-specific systemic antibiotics, stabilisation, dead space
filling with the biocomposite and primary skin closure. Aims
