The aim of this study was to evaluate the cost-effectiveness of arthroscopic partial meniscectomy versus physical therapy plus optional delayed arthroscopic partial meniscectomy in young patients aged under 45 years with traumatic meniscal tears. We conducted a multicentre, open-labelled, randomized controlled trial in patients aged 18 to 45 years, with a recent onset, traumatic, MRI-verified, isolated meniscal tear without knee osteoarthritis. Patients were randomized to arthroscopic partial meniscectomy or standardized physical therapy with an optional delayed arthroscopic partial meniscectomy after three months of follow-up. We performed a cost-utility analysis on the randomization groups to compare both treatments over a 24-month follow-up period. Cost utility was calculated as incremental costs per quality-adjusted life year (QALY) gained of arthroscopic partial meniscectomy compared to physical therapy. Calculations were performed from a healthcare system perspective and a societal perspective.Aims
Methods
The aims of this study were to determine if an increasing serum cobalt (Co) and/or chromium (Cr) concentration is correlated with a decreasing Harris Hip Score (HHS) and Hip disability and Osteoarthritis Outcome Score (HOOS) in patients who received the Articular Surface Replacement (ASR) hip resurfacing arthroplasty (HRA), and to evaluate the ten-year revision rate and show if sex, inclination angle, and Co level influenced the revision rate. A total of 62 patients with an ASR-HRA were included and monitored yearly postoperatively. At follow-up, serum Co and Cr levels were measured and the HHS and the HOOS were scored. In addition, preoperative patient and implant variables and the need for revision surgery were recorded. We used a linear mixed model to relate the serum Co and Cr levels to different patient-reported outcome measures (PROMs). For the survival analyses we used the Kaplan-Meier and Cox regression model.Aims
Methods
Meeting preoperative expectations is known to be of major influence on postoperative satisfaction after total knee arthroplasty (TKA). Improved management of expectation, resulting in more realistic expectations can potentially lead to higher postoperative satisfaction. The objective of this study was to assess the effect of an additional preoperative education module, addressing realistic expectations for long-term functional recovery, on postoperative satisfaction and expectation fulfilment. In total, 204 primary TKA patients with osteoarthritis were enrolled in this randomized controlled trial (RCT). Patients were allocated to either usual preoperative education (control group) or usual education plus an additional module on realistic expectations (intervention group). Primary outcome was being very satisfied (numerical rating scale for satisfaction ≥ 8) with the treatment result at 12 months' follow-up. Other outcomes were change in preoperative expectations and postoperative expectation fulfilment.Aims
Methods
Little is known about the risk factors that predispose to a rupture of the posterior cruciate ligament (PCL). Identifying risk factors is the first step in trying to prevent a rupture of the PCL from occurring. The morphology of the knee in patients who rupture their PCL may differ from that of control patients. The purpose of this study was to identify any variations in bone morphology that are related to a PCL. We compared the anteroposterior (AP), lateral, and Rosenberg view radiographs of 94 patients with a ruptured PCL to a control group of 168 patients matched by age, sex, and body mass index (BMI), but with an intact PCL after a knee injury. Statistical shape modelling software was used to assess the shape of the knee and determine any difference in anatomical landmarks.Aims
Patients and Methods
Open reduction is required following failed conservative treatment
of developmental dysplasia of the hip (DDH). The Ludloff medial
approach is commonly used, but poor results have been reported,
with rates of the development of avascular necrosis (AVN) varying
between 8% and 54%. This retrospective cohort study evaluates the
long-term radiographic and clinical outcome of dislocated hips treated
using this approach. Children with a dislocated hip, younger than one year of age
at the time of surgery, who were treated using a medial approach
were eligible for the study. Radiographs were evaluated for the
degree of dislocation and the presence of an ossific nucleus preoperatively,
and for the degree of AVN and residual dysplasia at one and five
years and at a mean of 12.7 years (4.6 to 20.8) postoperatively.
Radiographic outcome was assessed using the Severin classification,
after five years of age. Further surgical procedures were recorded.
Functional outcome was assessed using the Pediatric Outcomes Data
Collection Instrument (PODCI) or the Hip Disability and Osteoarthritis
Outcome Score (HOOS), depending on the patient’s age.Aims
Patients and Methods
The aim of this study was to assess the current available evidence
about when patients might resume driving after elective, primary
total hip (THA) or total knee arthroplasty (TKA) undertaken for
osteoarthritis (OA). In February 2016, EMBASE, MEDLINE, Web of Science, Scopus, Cochrane,
PubMed Publisher, CINAHL, EBSCO and Google Scholar were searched
for clinical studies reporting on ‘THA’, ‘TKA’, ‘car driving’, ‘reaction
time’ and ‘brake response time’. Two researchers (CAV and JJT) independently
screened the titles and abstracts for eligibility and assessed the
risk of bias. Both fixed and random effects were used to pool data
and calculate mean differences (MD) and 95% confidence intervals
(CI) between pre- and post-operative total brake response time (TBRT).Aims
Materials and Methods
We have investigated whether shape of the knee
can predict the clinical outcome of patients after an anterior cruciate
ligament rupture. We used statistical shape modelling to measure
the shape of the knee joint of 182 prospectively followed patients
on lateral and Rosenberg view radiographs of the knee after a rupture
of the anterior cruciate ligament. Subsequently, we associated knee
shape with the International Knee Documentation Committee subjective
score at two years follow-up. The mean age of patients was 31 years
(21 to 51), the majority were male (n = 121) and treated operatively
(n = 135). We found two modes (shape variations) that were significantly
associated with the subjective score at two years: one for the operatively
treated group (p = 0.002) and one for the non-operatively treated
group (p = 0.003). Operatively treated patients who had higher subjective
scores had a smaller intercondylar notch and a smaller width of
the intercondylar eminence. Non-operatively treated patients who
scored higher on the subjective score had a more pyramidal intercondylar
notch as opposed to one that was more dome-shaped. We conclude that
the shape of the femoral notch and the intercondylar eminence is predictive
of clinical outcome two years after a rupture of the anterior cruciate
ligament. Cite this article:
Forearm fractures in children have a tendency
to displace in a cast leading to malunion with reduced functional
and cosmetic results. In order to identify risk factors for displacement,
a total of 247 conservatively treated fractures of the forearm in
246 children with a mean age of 7.3 years ( Fractures of both forearm bones in children have a strong tendency
to displace even in an above-elbow cast. Severe fractures of the
non-dominant arm are at highest risk for displacement. Radiographs
at set times during treatment might identify early displacement,
which should be treated before malunion occurs, especially in older children
with less potential for remodelling. Cite this article:
We present the long-term outcome, at a median of 18 years (12.8 to 23.5) of open posterior bone block stabilisation for recurrent posterior instability of the shoulder in a heterogenous group of 11 patients previously reported on in 2001 at a median follow-up of six years. We found that five (45%) would not have chosen the operation again, and that four (36%) had further posterior dislocation. Clinical outcome was significantly worse after 18 years than after six years of follow-up (median Rowe score of 60 versus 90 (p = 0.027)). The median Western Ontario Shoulder Index was 60% (37% to 100%) at 18 years’ follow-up, which is a moderate score. At the time of surgery four (36%) had glenohumeral radiological osteoarthritis, which was present in all after 18 years. This study showed poor long-term results of the posterior bone block procedure for posterior instability and a high rate of glenohumeral osteoarthritis although three patients with post-traumatic instability were pleased with the result of their operations.
