A retrospective review was performed of patients
undergoing primary cementless
There is little in the literature on the level
of participation in sports which patients undertake after total
hip replacement (THR). Our aims in this study were to determine
first, the level of sporting activity, second, the predictive factors
for returning to sporting activity, and third, the correlation between
participation in sports and satisfaction after THR. We retrospectively
identified 815 patients who had undergone THR between 1995 and 2005. All
were asked to complete a self-administered questionnaire regarding
their sporting activity. A total of 571 patients (71%) met the inclusion
criteria and completed the evaluation. At a mean follow-up of 9.8
years ( In conclusion, we found that most patients participate in sporting
activity after THR, regardless of the advice of their surgeon, and
that there is a correlation between the level of participation and
pre-operative function, motivation, duration of symptoms and post-operative
satisfaction. Cite this article:
Total hip replacement causes a short-term increase
in the risk of mortality. It is important to quantify this and to identify
modifiable risk factors so that the risk of post-operative mortality
can be minimised. We performed a systematic review and critical
evaluation of the current literature on the topic. We identified
32 studies published over the last 10 years which provide either
30-day or 90-day mortality data. We estimate the pooled incidence
of mortality during the first 30 and 90 days following hip replacement
to be 0.30% (95% CI 0.22 to 0.38) and 0.65% (95% CI 0.50 to 0.81),
respectively. We found strong evidence of a temporal trend towards
reducing mortality rates despite increasingly co-morbid patients.
The risk factors for early mortality most commonly identified are
increasing age, male gender and co-morbid conditions, particularly
cardiovascular disease. Cardiovascular complications appear to have
overtaken fatal pulmonary emboli as the leading cause of death after
hip replacement. Cite this article:
The outcome after total hip replacement has improved
with the development of surgical techniques, better pain management
and the introduction of enhanced recovery pathways. These pathways
require a multidisciplinary team to manage pre-operative education,
multimodal pain control and accelerated rehabilitation. The current economic
climate and restricted budgets favour brief hospitalisation while
minimising costs. This has put considerable pressure on hospitals
to combine excellent results, early functional recovery and shorter
admissions. In this review we present an evidence-based summary of some common
interventions and methods, including pre-operative patient education,
pre-emptive analgesia, local infiltration analgesia, pre-operative
nutrition, the use of pulsed electromagnetic fields, peri-operative
rehabilitation, wound dressings, different surgical techniques, minimally
invasive surgery and fast-track joint replacement units. Cite this article:
Hip arthrodesis remains a viable surgical technique
in well selected patients, typically the young manual labourer with
isolated unilateral hip disease. Despite this, its popularity with
patients and surgeons has decreased due to the evolution of hip
replacement, and is seldom chosen by young adult patients today.
The surgeon is more likely to encounter a patient who requests conversion
to total hip replacement (THR). The most common indications are
a painful pseudarthrosis, back pain, ipsilateral knee pain or contralateral
hip pain. Occasionally the patient will request conversion because
of difficulty with activities of daily living, body image and perceived
cosmesis. The technique of conversion and a discussion of the results
are presented. Cite this article:
Patient safety is a critical issue in elective
total joint replacement surgery. Identifying risk factors that might
predict complications and intensive care unit (ICU) admission proves instrumental
in reducing morbidity and mortality. The institution’s experience
with risk stratification and pre-operative ICU triage has resulted
in a reduction in unplanned ICU admissions and post-operative complications
after total hip replacement. The application of the prediction tools
to total knee replacement has proven less robust so far. This work
also reviews areas for future research in patient safety and cost
containment. Cite this article:
We evaluated the outcome of primary total hip replacement (THR) in 3290 patients with the primary diagnosis of osteoarthritis at a minimum follow-up of two years. They were stratified into categories of body mass index (BMI) based on the World Health Organisation classification of obesity. Statistical analysis was carried out to determine if there was a difference in the post-operative Western Ontario and McMaster Universities osteoarthritis index, the Harris hip score and the Short-Form-12 outcome based on the BMI. While the pre- and post-operative scores were lower for the group classified as morbidly obese, the overall change in outcome scores suggested an equal if not greater improvement compared with the non-morbidly obese patients. The overall survivorship and rate of complications were similar in the BMI groups although there was a slightly higher rate of revision for sepsis in the morbidly obese group. Morbid obesity does not affect the post-operative outcome after THR, with the possible exception of a marginally increased rate of infection. Therefore withholding surgery based on the BMI is not justified.
We describe the results of cemented total hip replacement in 23 patients (23 hips) with active tuberculous arthritis of the hip with a mean follow-up of 4.7 years (4 to 7). In two patients the diagnosis was proved by pre-operative biopsy, whereas all others were diagnosed on a clinicoradiological basis with confirmation obtained by histopathological examination and polymerase chain reaction of tissue samples taken at the time of surgery. All patients received chemotherapy for at least three months before surgery and treatment was continued for a total of 18 months. Post-operative dislocation occurred in one patient and was managed successfully by closed reduction. No reactivation of the infection or loosening of the implant was recorded and function of the hip improved in all patients. Total hip replacement in the presence of active tuberculous arthritis of the hip is a safe procedure when pre-operative chemotherapy is commenced and continued for an extended period after operation.
Little is known about the efficacy of graduated compression stockings in preventing venous thromboembolism after hip surgery. We conducted a prospective, randomised single-blind study to determine whether the addition of compression stockings to fondaparinux conferred any additional benefit. The study included 874 patients, of whom 795 could be evaluated (400 in the fondaparinux group and 395 in the fondaparinux plus compression stocking group). Fondaparinux was given post-operatively for five to nine days, either alone or combined with wearing stockings, which were worn for a mean 42 days (35 to 49). The study outcomes were venous thromboembolism, or sudden death before day 42. Duplex ultrasonography was scheduled within a week of day 42. Safety outcomes were bleeding and death from venous thromboembolism. The prevalence of deep-vein thrombosis was similar in the two groups 5.5% (22 of 400) in the fondaparinux group and 4.8 (19 of 395) in the fondaparinux plus stocking group (odds ratio 0.88, 95% confidence interval 0.46 to 1.65, p = 0.69). Major bleeding occurred in only one patient. The addition of graduated compression stockings to fondaparinux appears to offer no additional benefit over the use of fondaparinux alone.
We performed a randomised, radiostereometric study comparing two different bone cements, one of which has been sparsely clinically documented. Randomisation of 60 total hip replacements (57 patients) into two groups of 30 was undertaken. All the patients were operated on using a cemented Charnley total hip replacement, the only difference between groups being the bone cement used to secure the femoral component. The two cements used were Palamed G and Palacos R with gentamicin. The patients were followed up with repeated clinical and radiostereometric examinations for two years to assess the micromovement of the femoral component and the clinical outcome. The mean subsidence was 0.18 mm and 0.21 mm, and the mean internal rotation was 1.7° and 2.0° at two years for the Palamed G and Palacos R with gentamicin bone cements, respectively. We found no statistically significant differences between the groups. Micromovement occurred between the femoral component and the cement, while the cement mantle was stable inside the bone. The Harris hip score improved from a mean of 38 points (14 to 54) and 36 (10 to 57) pre-operatively to a mean of 92 (77 to 100) and 91 (63 to 100) at two years in the Palamed G and Palacos R groups, respectively. No differences were found between the groups. Both bone cements provided good initial fixation of the femoral component and good clinical results at two years.
