The early diagnosis of cauda equina syndrome (CES) is crucial for a favourable outcome. Several studies have reported the use of an ultrasound scan of the bladder as an adjunct to assess the minimum post-void residual volume of urine (mPVR). However, variable mPVR values have been proposed as a threshold without consensus on a value for predicting CES among patients with relevant symptoms and signs. The aim of this study was to perform a meta-analysis and systematic review of the published evidence to identify a threshold mPVR value which would provide the highest diagnostic accuracy in patients in whom the diagnosis of CES is suspected. The search strategy used electronic databases (PubMed, Medline, EMBASE, and AMED) for publications between January 1996 and November 2021. All studies that reported mPVR in patients in whom the diagnosis of CES was suspected, followed by MRI, were included.Aims

Like athletes, musicians are vulnerable to musculoskeletal
injuries that can be career ending or have a severe negative financial
impact. All ages are affected, with a peak incidence in the third
and fourth decades. Women are slightly more likely to be affected

Although periacetabular osteotomies are widely used for the treatment of symptomatic dysplastic hips, long-term surgical outcomes and patient-reported outcome measures (PROMs) are still unclear. Accordingly, we assessed hip survival and PROMs at 20 years after transpositional osteotomy of the acetabulum (TOA). A total of 172 hips in 159 patients who underwent TOA were followed up at a mean of 21.02 years (16.6 to 24.6) postoperatively. Kaplan-Meier analysis was used to assess survivorship with an endpoint of total hip arthroplasty (THA). PROMs included the visual analogue scale (VAS) Satisfaction, VAS Pain, Oxford Hip Score (OHS), and Forgotten Joint Score-12 (FJS-12). Thresholds for favourable outcomes for OHS (≥ 42) and FJS-12 (≥ 51) were obtained using the receiver operating characteristic curve with VAS Satisfaction ≥ 50 and VAS Pain < 20 as anchors.Aims
Methods
The aim of this study was to compare any differences in the primary outcome (biphasic flexion knee moment during gait) of robotic arm-assisted bi-unicompartmental knee arthroplasty (bi-UKA) with conventional mechanically aligned total knee arthroplasty (TKA) at one year post-surgery. A total of 76 patients (34 bi-UKA and 42 TKA patients) were analyzed in a prospective, single-centre, randomized controlled trial. Flat ground shod gait analysis was performed preoperatively and one year postoperatively. Knee flexion moment was calculated from motion capture markers and force plates. The same setup determined proprioception outcomes during a joint position sense test and one-leg standing. Surgery allocation, surgeon, and secondary outcomes were analyzed for prediction of the primary outcome from a binary regression model.Aims
Methods
The aim of this study was to compare the clinical outcomes of robotic arm-assisted bi-unicompartmental knee arthroplasty (bi-UKA) with conventional mechanically aligned total knee arthroplasty (TKA) during the first six weeks and at one year postoperatively. A per protocol analysis of 76 patients, 43 of whom underwent TKA and 34 of whom underwent bi-UKA, was performed from a prospective, single-centre, randomized controlled trial. Diaries kept by the patients recorded pain, function, and the use of analgesics daily throughout the first week and weekly between the second and sixth weeks. Patient-reported outcome measures (PROMs) were compared preoperatively, and at three months and one year postoperatively. Data were also compared longitudinally and a subgroup analysis was conducted, stratified by preoperative PROM status.Aims

We aimed to determine hip-related quality of life and clinical findings following treatment for neonatal hip instability (NHI) compared with age- and sex-matched controls. We hypothesized that NHI would predispose to hip discomfort in long-term follow-up. We invited those born between 1995 and 2001 who were treated for NHI at our hospital to participate in this population-based study. We included those that had Von Rosen-like splinting treatment started before one month of age. A total of 96 patients treated for NHI (75.6 %) were enrolled. A further 94 age- and sex-matched controls were also recruited. The Copenhagen Hip and Groin Outcome Score (HAGOS) questionnaire was completed separately for both hips, and a physical examination was performed.Aims
Methods
We conducted a study to determine whether radiological parameters
correlate with patient reported functional outcome, health-related
quality of life and physical measures of function in patients with
a fracture of the distal radius. The post-operative palmar tilt and ulnar variance at six weeks
and 12 months were correlated with the Patient Rated Wrist Evaluation,
Disabilities of the Arm, Shoulder and Hand, and EuroQol scores,
grip strength, pinch strength and range of movement at three, six
and 12 months for 50 patients (mean age 57 years; 26 to 85) having surgical
fixation, with either percutaneous pinning or reconstruction with
a volar plate, for a fracture of the distal radius.Aims
Patients and Methods
The aim of this study was to assess the effect
of injecting genetically engineered chondrocytes expressing transforming
growth factor beta 1 (TGF-β1) into the knees of patients with osteoarthritis.
We assessed the resultant function, pain and quality of life. A total of 54 patients (20 men, 34 women) who had a mean age
of 58 years (50 to 66) were blinded and randomised (1:1) to receive
a single injection of the active treatment or a placebo. We assessed
post-treatment function, pain severity, physical function, quality
of life and the incidence of treatment-associated adverse events. Patients
were followed at four, 12 and 24 weeks after injection. At final follow-up the treatment group had a significantly greater
improvement in the mean International Knee Documentation Committee
score than the placebo group (16 points; -18 to 49, This technique may result in improved clinical outcomes, with
the aim of slowing the degenerative process, leading to improvements
in pain and function. However, imaging and direct observational
studies are needed to verify cartilage regeneration. Nevertheless,
this study provided a sufficient basis to proceed to further clinical testing. Cite this article:
This study demonstrates a significant correlation
between the American Knee Society (AKS) Clinical Rating System and
the Oxford Knee Score (OKS) and provides a validated prediction
tool to estimate score conversion. A total of 1022 patients were prospectively clinically assessed
five years after TKR and completed AKS assessments and an OKS questionnaire.
Multivariate regression analysis demonstrated significant correlations between
OKS and the AKS knee and function scores but a stronger correlation
(r = 0.68, p <
0.001) when using the sum of the AKS knee and
function scores. Addition of body mass index and age (other statistically
significant predictors of OKS) to the algorithm did not significantly
increase the predictive value. The simple regression model was used to predict the OKS in a
group of 236 patients who were clinically assessed nine to ten years
after TKR using the AKS system. The predicted OKS was compared with
actual OKS in the second group. Intra-class correlation demonstrated
excellent reliability (r = 0.81, 95% confidence intervals 0.75 to
0.85) for the combined knee and function score when used to predict
OKS. Our findings will facilitate comparison of outcome data from
studies and registries using either the OKS or the AKS scores and
may also be of value for those undertaking meta-analyses and systematic
reviews. Cite this article:
Our goal was to evaluate the use of Ponseti’s
method, with minor adaptations, in the treatment of idiopathic clubfeet
presenting in children between five and ten years of age. A retrospective
review was performed in 36 children (55 feet) with a mean age of
7.4 years (5 to 10), supplemented by digital images and video recordings
of gait. There were 19 males and 17 females. The mean follow-up
was 31.5 months (24 to 40). The mean number of casts was 9.5 (6
to 11), and all children required surgery, including a percutaneous
tenotomy or open tendo Achillis lengthening (49%), posterior release
(34.5%), posterior medial soft-tissue release (14.5%), or soft-tissue
release combined with an osteotomy (2%). The mean dorsiflexion of
the ankle was 9° (0° to 15°). Forefoot alignment was neutral in
28 feet (51%) or adducted (<
10°) in 20 feet (36%), >
10° in
seven feet (13%). Hindfoot alignment was neutral or mild valgus
in 26 feet (47%), mild varus (<
10°) in 19 feet (35%), and varus
(>
10°) in ten feet (18%). Heel–toe gait was present in 38 feet
(86%), and 12 (28%) exhibited weight-bearing on the lateral border
(out of a total of 44 feet with gait videos available for analysis).
Overt relapse was identified in nine feet (16%, six children). The
parents of 27 children (75%) were completely satisfied. A plantigrade foot was achieved in 46 feet (84%) without an extensive
soft-tissue release or bony procedure, although under-correction
was common, and longer-term follow-up will be required to assess
the outcome. Cite this article:
The aim of this study was to determine the association
between the Oxford knee score (OKS) and direct assessment of outcome,
and to examine how this relationship varied at different time-points
following total knee replacement (TKR). Prospective data consisting
of the OKS, numerical rating scales for ‘worst pain’ and ‘perceived
mean daily pain’, timed functional assessments (chair rising, stairs
and walking ability), goniometry and lower limb power were recorded
for 183 patients pre-operatively and at six, 26 and 52 weeks post-operatively.
The OKS was influenced primarily by the patient’s level of pain
rather than objective functional assessments. The relationship between report
of outcome and direct assessment changed over time: R2 =
35% pre-operatively, 44% at six weeks, 57% at 26 weeks and 62% at
52 weeks. The relationship between assessment of performance and report
of performance improved as the patient’s report of pain diminished,
suggesting that patients’ reporting of functional outcome after
TKR is influenced more by their pain level than their ability to
accomplish tasks.
We conducted a longitudinal study including patients with the same type of primary hybrid total hip replacement and evaluated patient activity and femoral osteolysis at either five or ten years post-operatively. Activity was measured using the University of California, Los Angeles scale. The primary outcome was the radiological assessment of femoral osteolysis. Secondary outcomes were revision of the femoral component for aseptic loosening and the patients’ quality of life. Of 503 hip replacements in 433 patients with a mean age of 67.7 years (30 to 91), 241 (48%) were seen at five and 262 (52%) at ten years post-operatively. Osteolytic lesions were identified in nine of 166 total hip replacements (5.4%) in patients with low activity, 21 of 279 (7.5%) with moderate activity, and 14 of 58 (24.1%) patients with high activity. The risk of osteolysis increased with participation in a greater number of sporting activities. In multivariate logistic regression adjusting for age, gender, body mass index and the inclination angle of the acetabular component, the adjusted odds ratio for osteolysis comparing high In conclusion, of patients engaged in high activity, 24% had developed femoral osteolysis five to ten years post-operatively.
