Tranexamic acid (TXA) is proven to reduce blood loss following total knee arthroplasty (TKA), but there are limited data on the impact of similar dosing regimens in revision TKA. The purpose of this multicentre randomized clinical trial was to determine the optimal regimen to maximize the blood-sparing properties of TXA in revision TKA. From six-centres, 233 revision TKAs were randomized to one of four regimens: 1 g of intravenous (IV) TXA given prior to the skin incision, a double-dose regimen of 1 g IV TXA given both prior to skin incision and at time of wound closure, a combination of 1 g IV TXA given prior to skin incision and 1 g of intraoperative topical TXA, or three doses of 1950 mg oral TXA given two hours preoperatively, six hours postoperatively, and on the morning of postoperative day one. Randomization was performed based on the type of revision procedure to ensure equivalent distribution among groups. Power analysis determined that 40 patients per group were necessary to identify a 1 g/dl difference in the reduction of haemoglobin postoperatively between groups with an alpha of 0.05 and power of 0.80. Per-protocol analysis involved regression analysis and two one-sided Aims
Patients and Methods
Recurrent infection following two-stage revision total hip arthroplasty
(THA) for prosthetic joint infection (PJI) is a devastating complication.
The purpose of this study was to report the survival of repeat two-stage
revision hip arthroplasty, describe complications, and identify
risk factors for failure. We retrospectively identified 19 hips (19 patients) that had
undergone repeat two-stage revision THA for infection between 2000
to 2013. There were seven female patients (37%) and the mean age
was 60 years (30 to 85). Survival free from revision was assessed
via Kaplan–Meier analysis. The patients were classified according
to the Musculoskeletal Infection Society (MSIS) system, and risk
factors for failure were identified. Mean follow-up was four years
(2 to 11).Aims
Patients and Methods
Short-stemmed femoral implants have been used for total hip arthroplasty (THA) in young and active patients to conserve bone, provide physiological loading, and reduce the incidence of thigh pain. Only short- to mid-term results have been presented and there have been concerns regarding component malalignment, incorrect sizing, and subsidence. This systematic review reports clinical and radiological outcomes, complications, revision rates, and implant survival in THA using short-stemmed femoral components. A literature review was performed using the EMBASE, Medline, and Cochrane databases. Strict inclusion and exclusion criteria were used to identify studies reporting clinical and radiological follow-up for short-stemmed hip arthroplasties.Aims

The use of a noninvasive growing endoprosthesis in the management
of primary bone tumours in children is well established. However,
the efficacy of such a prosthesis in those requiring a revision
procedure has yet to be established. The aim of this series was
to present our results using extendable prostheses for the revision
of previous endoprostheses. All patients who had a noninvasive growing endoprosthesis inserted
at the time of a revision procedure were identified from our database.
A total of 21 patients (seven female patients, 14 male) with a mean
age of 20.4 years (10 to 41) at the time of revision were included.
The indications for revision were mechanical failure, trauma or infection
with a residual leg-length discrepancy. The mean follow-up was 70
months (17 to 128). The mean shortening prior to revision was 44 mm
(10 to 100). Lengthening was performed in all but one patient with
a mean lengthening of 51 mm (5 to 140).Aims
Patients and Methods
Few reconstructive techniques are available for patients requiring
complex acetabular revisions such as those involving Paprosky type
2C, 3A and 3B deficiencies and pelvic discontinuity. Our aim was
to describe the development of the patient specific Triflange acetabular
component for use in these patients, the surgical technique and
mid-term results. We include a description of the pre-operative
CT scanning, the construction of a model, operative planning, and
surgical technique. All implants were coated with porous plasma
spray and hydroxyapatite if desired. A multicentre, retrospective review of 95 complex acetabular
reconstructions in 94 patients was performed. A total of 61 (64.2%)
were female. The mean age of the patients was 66 (38 to 85). The
mean body mass index was 29 kg/m2 (18 to 51). Outcome
was reported using the Harris Hip Score (HHS), complications, failures
and survival.Aims
Patients and Methods
The aims of this study were to determine the clinical and radiographic
outcomes, implant survivorship, and complications of patients with
a history of poliomyelitis undergoing total hip arthroplasty (THA)
in affected limbs and unaffected limbs of this same population. A retrospective review identified 51 patients (27 male and 24
female, 59 hips) with a mean age of 66 years (38 to 88) and with
the history of poliomyelitis who underwent THA for degenerative
arthritis between 1970 and 2012. Immigrant status, clinical outcomes,
radiographic results, implant survival, and complications were recorded.Aims
Patients and Methods
Tapered fluted titanium stems are increasingly
used for femoral revision arthroplasty. They are available in modular and
non-modular forms. Modularity has advantages when the bone loss
is severe, the proximal femur is mis shapen or the surgeon is unfamiliar
with the implant, but it introduces the risk of fracture of the
stem at the junction between it and the proximal body segment. For
that reason, and while awaiting intermediate-term results of more recently
introduced designs of this junction, non-modularity has attracted
attention, at least for straightforward revision cases. We review the risks and causes of fracture of tapered titanium
modular revision stems and present an argument in favour of the
more selective use of modular designs. Cite this article:
The aim of this study was to investigate the outcomes of Vancouver
type B2 and B3 fractures by performing a systematic review of the
methods of surgical treatment which have been reported. A systematic search was performed in Ovid MEDLINE, Embase and
the Cochrane Central Register of Controlled Trials. For inclusion,
studies required a minimum of ten patients with a Vancouver type
B2 and/or ten patients with a Vancouver type B3 fracture, a minimum
mean follow-up of two years and outcomes which were matched to the type
of fracture. Studies were also required to report the rate of re-operation
as an outcome measure. The protocol was registered in the PROSPERO
database. Aims
Materials and Methods
The goals of this study were to define the risk factors, characteristics,
and chronology of fractures in 5417 revision total hip arthroplasties
(THAs). From our hospital’s prospectively collected database we identified
all patients who had undergone a revision THA between 1969 and 2011
which involved the femoral stem. The patients’ medical records and
radiographs were examined and the relevant data extracted. Post-operative
periprosthetic fractures were classified using the Vancouver system.
A total of 5417 revision THAs were identified.Aims

We carried out a further study of the long-term results of the
cemented Exeter femoral component in patients under the age of 40
with a mean follow-up of 13.6 years (10 to 20). We reviewed our original cohort of 104 cemented Exeter stems
in 78 consecutive patients with a mean age of 31 years (16 to 39).
Only one patient was lost to radiological follow-up.Aims
Patients and Methods
The aim of this study was to compare the survivorship and radiographic
outcomes at ten-year follow-up of three prospective consecutive
series of patients each of which received a different design of
cementless femoral components for total hip arthroplasty (THA). In Cohort 1, 91 consecutive patients (100 hips) underwent THA
with a cementless porous-coated anatomic femoral stem (PCA) between
October 1983 and January 1986. In Cohort 2, 86 consecutive patients
(100 hips) underwent THA with an extensively porous-coated cementless
femoral stem (Prodigy) between June 1994 and October 1997. In Cohort
3, 88 consecutive patients (100 hips) underwent THA with a proximally
porous-coated triple-tapered cementless stem (Summit) between April
2002 and October 2003. All three groups underwent prospective clinical
and radiographic evaluation.Aims
Patients and Methods
In this retrospective study, we investigated
the results of revision total hip replacement (THR) using a cemented long-stemmed
Exeter femoral component, with a minimum length of 205 mm in patients
with extensive femoral bone defects. The study included 37 consecutive
patients with a mean age of 76 years (39 to 93) and a mean follow-up
of nine years (5 to 16). A total of 26 patients (70%) had a pre-operative
Endo-Klinik score of 3 or 4. Impaction bone grafting was used in
24 patients (65%). At the time of evaluation, 22 patients (59%)
were still alive and were evaluated clinically and radiologically.
A total of 14 patients died during follow-up and their data were
included until the time of their death. One reconstruction failed
after five years and five months owing to recurrent dislocation:
the hip was converted to an excision arthroplasty. Intra-operative
fractures or fissures were encountered in nine patients (24%), but
none occurred during impaction of the bone graft. Post-operative
peri-prosthetic fractures occurred in two patients (5%); both were
treated with plate fixation. At nine years, survival with the endpoint
of all-cause re-revision was 96.3% (95% CI 76.4 to 99.5); including
re-operations for any reason, it was 80.7% (95% CI 56.3 to 92.3%).
There were no re-revisions for aseptic loosening. The survival of long stem cemented femoral components following
revision THR is satisfactory in a fragile population with extensive
femoral defects. Cite this article:
Revision total hip arthroplasty (THA) is challenging
when there is severe loss of bone in the proximal femur. The purpose
of this study was to evaluate the clinical and radiographic outcomes
of revision THA in patients with severe proximal femoral bone loss
treated with a fluted, tapered, modular femoral component. Between
January 1998 and December 2004, 92 revision THAs were performed
in 92 patients using a single fluted, tapered, modular femoral stem
design. Pre-operative diagnoses included aseptic loosening, infection
and peri-prosthetic fracture. Bone loss was categorised pre-operatively
as Paprosky types III-IV, or Vancouver B3 in patients with a peri-prosthetic
fracture. The mean clinical follow-up was 6.4 years (2 to 12). A
total of 47 patients had peri-operative complications, 27 of whom
required further surgery. However, most of these further operations
involved retention of a well-fixed femoral stem, and 88/92 femoral
components (97%) remained Revision THA in patients with extensive proximal femoral bone
loss using the Link MP fluted, tapered, modular stem led to a high
rate of osseointegration of the stem at mid-term follow-up. Cite this article:
This study reports on the first 150 consecutive
Oxford cementless unicompartmental knee arthroplasties (UKA) performed
in an independent centre (126 patients). All eligible patients had
functional scores (Oxford knee score and high activity arthroplasty
score) recorded pre-operatively and at two- and five-years of follow-up. Fluoroscopically
aligned radiographs were taken at five years and analysed for any
evidence of radiolucent lines (RLLs), subsidence or loosening. The
mean age of the cohort was 63.6 years (39 to 86) with 81 (53.1%)
males. Excellent functional scores were maintained at five years
and there were no progressive RLLs demonstrated on radiographs.
Two patients underwent revision to a total knee arthroplasty giving
a revision rate of 0.23/100 (95% confidence interval 0.03 to 0.84)
component years with overall component survivorship of 98.7% at
five years. There were a further four patients who underwent further
surgery on the same knee, two underwent bearing exchanges for dislocation
and two underwent lateral UKAs for disease progression. This was
a marked improvement from other UKAs reported in New Zealand Joint
Registry data and supports the designing centre’s early results. Cite this article:
