The direct anterior approach (DAA) for total hip arthroplasty (THA) has potential advantages over other approaches and is most commonly performed with the patient in the supine position. We describe a technique for DAA THA with the patient in the lateral decubitus position and report the early clinical and radiological outcomes, the characteristics of the learning curve, and perioperative complications. All primary DAA THAs performed in the lateral position by a single surgeon over a four-year period from the surgeon’s first case using the technique were identified from a prospectively collected database. Modified Harris Hip Scores (mHHS) were collected to assess clinical outcome, and routine radiological analysis was performed. Retrospective review of the medical records identified perioperative complications, the characteristics of the learning curve, and revisions.Aims
Methods
The purpose of this study was to determine the access to and ability to use telemedicine technology in adult patients undergoing total hip arthroplasty (THA) and total knee arthroplasty (TKA), and to determine associations with the socioeconomic characteristics of the patients, including age, sex, race, and education. We also sought to understand the patients’ perceived benefits, risks, and preferences when dealing with telemedicine. We performed a cross-sectional survey involving patients awaiting primary THA and TKA by one of six surgeons at a single academic institution. Patients were included and called for a telephone-administered survey if their surgery was scheduled to be between 23 March and 2 June 2020, and were aged > 18 years.Aims
Methods
Routine surveillance of primary hip and knee arthroplasties has traditionally been performed with office follow-up visits at one year postoperatively. The value of these visits is unclear. The present study aims to determine the utility and burden of routine clinical follow-up at one year after primary arthroplasty to patients and providers. All patients (473) who underwent primary total hip (280), hip resurfacing (eight), total knee (179), and unicompartmental knee arthroplasty (six) over a nine-month period at a single institution were identified from an institutional registry. Patients were prompted to attend their routine one-year postoperative visit by a single telephone reminder. Patients and surgeons were given questionnaires at the one-year postoperative visit, defined as a clinical encounter occurring at nine to 15 months from the date of surgery, regarding value of the visit.Aims
Methods
Whether patient-reported pain differs among surgical approaches in total hip arthroplasty (THA) remains unclear. This study’s purposes were to determine differences in pain based on surgical approach (direct anterior (DA) This was a retrospective investigation from two centres and seven surgeons (three DA, three PL, one both) of primary THAs. PL patients were categorized for incision length (6 cm to 8 cm, 8 cm to 12 cm, 12 cm to 15 cm). All patients had cementless femoral and acetabular fixation, at least one year’s follow-up, and well-fixed components. Patients completed a pain-drawing questionnaire identifying the location and intensity of pain on an anatomical diagram. Power analysis indicated 800 patients in each cohort for adequate power to detect a 4% difference in pain (alpha = 0.05, beta = 0.80).Aims
Patients and Methods
The aims of this study were to review the surgical technique for a combined femoral head reduction osteotomy (FHRO) and periacetabular osteotomy (PAO), and to report the short-term clinical and radiological results of a combined FHRO/PAO for the treatment of selected severe femoral head deformities. Between 2011 and 2016, six female patients were treated with a combined FHRO and PAO. The mean patient age was 13.6 years (12.6 to 15.7). Clinical data, including patient demographics and patient-reported outcome scores, were collected prospectively. Radiologicalally, hip morphology was assessed evaluating the Tönnis angle, the lateral centre to edge angle, the medial offset distance, the extrusion index, and the alpha angle.Aims
Patients and Methods
We report patient-reported outcomes and complications
associated with contemporary periacetabular osteotomy (PAO) surgery
in treating symptomatic acetabular dysplasia and compare these outcomes
with total hip arthroplasty (THA) in patients with similar demographic
details. Two consecutive cohorts included patients between aged
18 to 40 years who had undergone either PAO (100 hips; 24 male,
76 female) or THA (55 hips; 18 male, 37 female). At a mean follow-up
of 5.9 years (2 to 13), there was significant improvement in the
modified Harris hip pain (p <
0.001, PAO and p <
0.001, THA),
function (p <
0.001, PAO and p = 0.001, THA), and total scores
(p <
0.001, PAO and p <
0.001, THA) within each cohort. There
were no significant differences in the clinical outcome scores between
the groups. Complication rates were low and similar in each cohort
(p = 0.68). Similar to THA, contemporary PAO surgery is a clinically
effective procedure that improves function and activity levels,
provides pain relief and is associated with an acceptable complication
rate. Cite this article:
Obesity is a risk factor for complications following
many orthopaedic procedures. The purpose of this study was to investigate
whether obesity was an independent risk factor increasing the rate
of complications following periacetabular osteotomy (PAO) and to
determine whether radiographic correction after PAO was affected
by obesity. We retrospectively collected demographic, clinical and radiographic
data on 280 patients (231 women; 82.5% and 49 men; 17.5%) who were
followed for a mean of 48 months (12 to 60) after PAO. A total of
65 patients (23.2%) were obese (body mass index (BMI) >
30 kg/m2).
Univariate and multivariate analysis demonstrated that BMI was an independent
risk factor associated with the severity of the complications. The
average probability of a patient developing a major complication
was 22% (95% confidence interval (CI) 11.78 to 38.21) for an obese
patient compared with 3% (95% CI 1.39 to 6.58) for a non-obese patient
The odds of a patient developing a major complication were 11 times
higher (95% CI 4.71 to 17.60, p <
0.0001) for an obese compared
with a non-obese patient. Following PAO surgery, there was no difference in radiographic
correction between obese and non-obese patients. PAO procedures
in obese patients correct the deformity effectively but are associated
with an increased rate of complications. Cite this article:
Down’s syndrome is associated with a number of
musculoskeletal abnormalities, some of which predispose patients
to early symptomatic arthritis of the hip. The purpose of the present
study was to review the general and hip-specific factors potentially
compromising total hip replacement (THR) in patients with Down’s
syndrome, as well as to summarise both the surgical techniques that
may anticipate the potential adverse impact of these factors and
the clinical results reported to date. A search of the literature
was performed, and the findings further informed by the authors’
clinical experience, as well as that of the hip replacement in Down
Syndrome study group. The general factors identified include a high
incidence of ligamentous laxity, as well as associated muscle hypotonia
and gait abnormalities. Hip-specific factors include: a high incidence
of hip dysplasia, as well as a number of other acetabular, femoral
and combined femoroacetabular anatomical variations. Four studies
encompassing 42 hips, which reported the clinical outcomes of THR
in patients with Down’s syndrome, were identified. All patients
were successfully treated with standard acetabular and femoral components.
The use of supplementary acetabular screw fixation to enhance component
stability was frequently reported. The use of constrained liners
to treat intra-operative instability occurred in eight hips. Survival
rates of between 81% and 100% at a mean follow-up of 105 months
(6 to 292) are encouraging. Overall, while THR in patients with
Down’s syndrome does present some unique challenges, the overall
clinical results are good, providing these patients with reliable
pain relief and good function. Cite this article:
