Purpose:
Due to recent shifts in healthcare reimbursement models, more primary total hip arthroplasties (THAs) are now being performed in the outpatient setting. However, there is a lack of knowledge around the comparative outcomes of revision outpatient THA.
Materials and Methods:
Adults undergoing revision THA between 2010 and 2020 with 2-year follow-up data were identified on a large insurance claims database. Following stratification by inpatient versus outpatient revision THA, patients from both groups were matched 1:1 by demographics and revision characteristics. Ninety-day postoperative medical and 1- and 2-year postoperative surgical complications after matching were compared.
Results:
Among 67,570 patients, mean age was 65.3 years, 57.0% were female, and mean Charlson comorbidity index score was 1.72. Subsequent to 1:1 matching, 1,555 inpatient and outpatient revision THA patients were identified. Outpatient THA patients had significantly lower rates of blood transfusions (3.6% vs 5.1%, P=0.049), broken prosthesis (1 year: 0.1% vs.0.6%, P=0.027; 2 years: 0.2% vs. 0.9%, P=0.015), and other postoperative mechanical complications (1 year: 4.9% vs. 7.1%, P=0.010; 2 years: 6.2% vs. 8.4%, P=0.023). Otherwise, the data for outpatient THA patients was not statistically different from inpatient THA patients across all studied complications.
Conclusion
Outpatient revision THA may be a safe alternative to inpatient revision THA for carefully selected patients. Establishing patient- and case-specific parameters to optimize outcomes, satisfaction, safety, and value is critical.

Journal of Movement Disorders 2025;18(2):170-174
Objective:
Colony-stimulating factor 1 receptor-related leukoencephalopathy (CSF1R-L) is a rare adult-onset leukoencephalopathy. Reports of CSF1R-L patients from the Indian subcontinent remain limited. We aimed to report four patients with genetically confirmed CSF1R-L from four Asian Indian families and described their clinical, molecular, and radiological features.
Methods:
All patients underwent clinical examination, brain magnetic resonance imaging, and whole-exome sequencing to identify causative variants in the CSF1R gene. We also reviewed published reports of Indian patients with CSF1R-L.
Results:
The age at enrollment ranged from 34 to 40 years. The duration of symptoms ranged from 11 months to 2 years. The chief clinical phenotype in three patients was a rapidly evolving cognitive-behavioral syndrome combined with atypical parkinsonism, and asymmetrical spastic tetraparesis was observed in one patient. We identified four different variants (three missense variants and one in-frame deletion). Radiological findings revealed white matter involvement and diffusion restriction involving the subcortical white matter and pyramidal tracts.
Conclusion
We expand the literature on CSF1R-L patients from India by reporting four new cases.

Journal of Movement Disorders 2025;18(1):45-54
Objective:
To explore sleep patterns in individuals with essential tremor (ET) and essential tremor plus (ET-Plus) compared with healthy controls and assess differences between ET and ET-Plus, given the lack of established polysomnography (PSG) data on these groups and the potential for sleep disturbances to serve as clinical markers.
Methods:
We conducted a prospective cross-sectional study at National Institute of Mental Health and Neurosciences, Bengaluru, from November 2021 to August 2023 on 45 patients (26 ET, 19 ET-Plus) and 45 controls. Tremor severity was assessed using The Essential Tremor Rating Assessment Scale (TETRAS) and Fahn‐Tolosa‐Marin Clinical Rating Scale (FTMRS). Sleep symptoms were assessed via the Epworth Sleepiness Scale, Pittsburgh Sleep Quality Index, Mayo Sleep Questionnaire, restless legs syndrome questionnaire, Berlin questionnaire, Generalized Anxiety Disorder Scale 7, and Patient Health Questionnaire-9. All patients and controls underwent overnight video PSG. Sleep scoring was manually performed by a trained sleep research technician and the first author following the American Academy of Sleep Medicine (2017) guidelines, with data analyzed using R studio.
Results:
Compared with ET-Plus patients, ET patients had a younger onset age (46.8±11.1 years versus 30.8±16.7 years, respectively). Compared with ET patients, ET-Plus patients had higher TETRAS and FTMRS scores (p<0.005). Compared with controls, both ET patients and ET-Plus patients presented poorer sleep quality, excessive daytime sleepiness, rapid eye movement (REM) sleep behavior disorder, and restless legs syndrome symptoms. PSG findings supported these clinical observations, showing an elevated apnea‒hypopnea index, reduced total sleep time, prolonged REM latency, decreased sleep efficiency, increased N1 stage duration, and reduced N2/N3 durations and percentages in patients versus controls.
Conclusion
The study highlights significant sleep architecture abnormalities in both ET and ET-Plus patients compared with healthy controls, with no differences between the ET groups.

Malaysian Orthopaedic Journal 2025;19(No. 1):21-30
Introduction: The purpose of this study is to assess the
outcomes of patients that underwent single-stage revision
ACL reconstruction (ACLR) with peroneus longus tendon
(PLT), augmented with lateral extra-articular tenodesis
(LET) using the modified Lemaire technique.
Materials and methods: All the 18 patients underwent
arthroscopic single-stage revision ACLR using autologous
PLT with an additional modified Limier LET procedure.
Patients were thoroughly assessed pre- and post-operatively
by the Lachman test, the pivot shift test, and the side-to-side
difference by the Rolimeter. Functional evaluation was done
with the help of the Lysholm score, the IKDC subjective
score, Tegner score, VAS score, MARX activity rating scale
and The American Orthopaedic Foot and Ankle Society
(AOFAS) score. Post-operatively, patient satisfaction, return
to sport, and physical activity were also recorded. SPSS ver.
22.0 software was used. Wilcoxon test, paired and unpaired
t-tests were used to compare variables. Statistical
significance was determined by a two-sided p-value <0.05.
Results: Regarding subjective evaluations; post-operative
residual laxity, and return to sport and physical activity, all of
the patients demonstrated excellent results. Post-operatively,
there was significant improvement in the anterior knee
laxity. According to the Marx Activity Rating Scale, the
extent of sports engagement was significantly increased at 18
months following surgery (p<0.001). According to the
AOFAS score (p=0.38), there were no documented
significant donor site morbidities.
Conclusions: Single-stage revision ACLR using PLT with
an additional modified Lemaire LET procedure results in a
significant reduction in residual knee laxity with good
clinical outcomes and a high return to play and physical
activity

Clinical Psychopharmacology and Neuroscience 2024;22(1):33-44
Objective:
To explore illness-related factors in patients with major depressive disorder (MDD) recipients of adjunctive minocycline (200 mg/day) treatment. The analysis included participants experiencing MDD from a 12-week, double blind, placebo-controlled, randomized clinical trial (RCT).
Methods:
This is a sub-analysis of a RCT of all 71 participants who took part in the trial. The impact of illness chronicity (illness duration and number of depressive episodes), systemic illness (endocrine, cardiovascular and obesity), adverse effects and minocycline were evaluated as change from baseline to endpoint (12-week) using ANCOVA.
Results:
There was a consistent but statistically non-significant trend on all outcomes in favour of the use of adjunctive minocycline for participants without systemic illness, less illness chronicity, and fewer adverse effects.
Conclusion
Understanding the relationship between MDD and illness chronicity, comorbid systemic illness, and adverse effects, can potentially better characterise those individuals who are more likely to respond to adjunctive anti-inflammatory medications.

Neurospine 2024;21(1):253-260
Objective:
To evaluate preoperative disability’s influence on patient-reported outcomes (PROs) following surgery for degenerative spondylolisthesis (DS).
Methods:
DS patients who underwent surgical intervention were retrospectively identified from a single-surgeon spine registry. Cohorts based on Oswestry Disability Index (ODI) < 41 (milder disability) and ≥ 41 (severe disability) were created. Demographic differences were accounted for with 1:1 propensity score matching. For the matched sample, perioperative and PRO data were additionally collected. PROs assessed included mental health, physical function, pain, and disability. Pre- and up to 2-year postoperative PROs were utilized. Average time to final follow-up was 15.7 ± 8.8 months. Improvements in PROs and minimal clinically important difference (MCID) rates were calculated. Continuous variables were compared through Student t-test and categorical variables were compared through chi-square tests.
Results:
Altogether, 214 patients were included with 77 in the milder disability group. The severe disability group had worse postoperative day (POD) 1 pain scores and longer hospital stays (p ≤ 0.038, both). The severe disability group reported worse outcomes pre- and postoperatively (p < 0.011, all), but had greater average improvement in 12-item Short Form health survey mental composite score (SF-12 MCS), 9-Item Patient Health Questionnaire (PHQ-9), visual analogue scale (VAS)-back, and ODI by 6 weeks (p ≤ 0.037, all) and PHQ-9, VAS-back and ODI by final follow-up (p ≤ 0.015, all). The severe disability cohort was more likely to achieve MCID for SF-12 MCS, PHQ-9, and ODI (p ≤ 0.003, all).
Conclusion
Patients with greater baseline disability report higher POD 1 pain and discharge later than patients with milder disability. While these patients report inferior physical/mental health before and after surgery, they report greater improvements in mental health and disability postoperatively.
