Health economic evaluations potentially provide
valuable information to clinicians, health care administrators,
and policy makers regarding the financial implications of decisions
about the care of patients. The highest quality research should
be used to inform decisions that have direct impact on the access
to care and the outcome of treatment. However, economic analyses
are often complex and use research methods which are relatively unfamiliar
to clinicians. Furthermore, health economic data have substantial
national, regional, and institutional variability, which can limit
the external validity of the results of a study. Therefore, minimum
guidelines that aim to standardise the quality and transparency
of reporting health economic research have been developed, and instruments
are available to assist in the assessment of its quality and the
interpretation of results. The purpose of this editorial is to discuss the principal types
of health economic studies, to review the most common instruments
for judging the quality of these studies and to describe current
reporting guidelines. Recommendations for the submission of these
types of studies to Cite this article:
Total knee arthroplasty (TKA) is a cost effective
and extremely successful operation. As longevity increases, the demand
for primary TKA will continue to rise. The success and survivorship
of TKAs are dependent on the demographics of the patient, surgical
technique and implant-related factors. Currently the risk of failure of a TKA requiring revision surgery
ten years post-operatively is 5%. The most common indications for revision include aseptic loosening
(29.8%), infection (14.8%), and pain (9.5%). Revision surgery poses
considerable clinical burdens on patients and financial burdens
on healthcare systems. We present a current concepts review on the epidemiology of failed
TKAs using data from worldwide National Joint Registries. Cite this article:
Hip and groin injuries are common in athletes
who take part in high level sports. Adductor muscle tendon injuries represent
a small but important number of these injuries. Avulsion of the
tendons attached to the symphysis pubis has previously been described:
these can be managed both operatively and non-operatively. We describe
an uncommon variant of this injury, namely complete avulsion of
the adductor sleeve complex: this includes adductor longus, pectineus
and rectus abdominis. We go on to describe a surgical technique
which promotes a full return to the pre-injury level of sporting
activity. Over a period of ten years, 15 high-level athletes with an MRI-confirmed
acute adductor complex avulsion injury (six to 34 days old) underwent
surgical repair. The operative procedure consisted of anatomical
re-attachment of the avulsed tissues in each case and mesh reinforcement
of the posterior inguinal wall in seven patients. All underwent a
standardised rehabilitation programme, which was then individualised
to be sport-specific. One patient developed a superficial wound infection, which was
successfully treated with antibiotics. Of the 15 patients, four
complained of transient local numbness which resolved in all cases.
All patients (including seven elite athletes) returned to their
previous level of participation in sport. Cite this article:
Recently, several high impact randomised controlled
trials have been published suggesting no greater benefit from orthopaedic
surgery over conservative treatment, or limited surgical intervention.
These studies can have profound effects on clinical practice, leading
to the abandonment of previously widely-used operations. How do surgeons who believe these operations are beneficial over
conservative treatment rationalise these findings, and justify their
use with hospital administrators and health care funders who require
evidence for the value and efficacy of surgical treatment? Cite this article:
Many aspects of total knee arthroplasty have
changed since its inception. Modern prosthetic design, better fixation techniques,
improved polyethylene wear characteristics and rehabilitation, have
all contributed to a large change in revision rates. Arthroplasty
patients now expect longevity of their prostheses and demand functional
improvement to match. This has led to a re-examination of the long-held
belief that mechanical alignment is instrumental to a successful
outcome and a focus on restoring healthy joint kinematics. A combination
of kinematic restoration and uncemented, adaptable fixation may
hold the key to future advances. Cite this article:
