- چکیده:
- چکیده انگلیسی: Background: There is no difference in the functional outcomes 6 months after total knee arthroplasty (TKA) for knee
osteoarthritis between patellar resurfacing and non-resurfacing. Thus, we have performed this study to compare the
short-term clinical outcomes of TKA performed with and without the patella resurfacing.
Methods: A total of 50 patients with osteoarthritis of the knee (OAK) were randomized to receive patellar resurfacing
(n=24; resurfaced group) or to retain their native patella (n=26; non-resurfaced group) based on envelope selection
and provided informed consent. Disease specific outcomes including Knee Society Score (KSS), Knee Society
Function Score (KSKS-F), Kujala Anterior Knee Pain Scale (AKPS), Western Ontario and McMaster Universities
Arthritis Index (WOMAC), Short Form 36 (SF-36), and functional patella-related activities were measured within six
months of follow-up.
Results: There was no significant difference between the resurfaced and non-resurfaced groups in pre and postoperative
improvement of range of motion (ROM) (P=0.421), KSS (P=0.782, P=0.553), KSKS-F (P=0.241, P=0.293),
AKPS (P=0.128, P=0.443), WOMAC (P=0.700, P=0.282), and pain scores (P=0.120, P=0.508). There was no
difference in ROM between resurfaced and non-resurfaced group pre (15.24° and 15.45°) and post-operative (18.48°
and 18.74). No side effects related to patella was observed in any of the groups. Revision was required in none of
the participants.
Conclusion: The results showed no significant difference between patellar resurfacing and non-resurfacing in TKA for
all outcome measures in a short term.- انتشار مقاله: 13-11-1395

- چکیده:
- چکیده انگلیسی: Background: Many studies have reported the association of estrogen receptor α gene (ESRα) ESRα PvuII T>C, XbaI A>G and BtgI G>A polymorphisms with Knee osteoarthritis (KOA) risk, but the results remained controversial. In order to drive a more precise estimation, the present systematic review and meta-analysis was performed to investigate the association between ESRα polymorphisms and KOA susceptibility. Methods: Eligible articles were identified by search of databases including PubMed, ISI Web of Knowledge and Google scholar up to March 1, 2017. Data were extracted by two independent authors and pooled odds ratio (OR) with 95% confidence interval (CI) was calculated. Results: A total of 22 case-control studies in eleven publications with 6,575 KOA cases and 7,459 controls were included in the meta-analysis. By pooling all the studies, either ESRα PvuII T>C and XbaI A>G polymorphisms was not associated with KOA risk in the overall population. However, ESRα BtgI G>A was significantly associated with KOA risk under all five genetic models. In the subgroup analysis by ethnicity, a significant association was observed between ESRα PvuII T>C polymorphism and KOA risk in Asians under heterozygote model. In addition, significant association was found between ESRα XbaI A>G polymorphism and KOA in Caucasians under allelic, homozygote, dominant and recessive models. Conclusion: The present meta-analysis suggests that ESRα BtgI G>A rather than ESRα PvuII T>C and XbaI A>G polymorphisms is associated with an increased KOA risk in overall population. Moreover, we have found that ESRα PvuII T>C and XbaI A>G polymorphisms associated with KOA susceptibility by ethnicity backgrounds.

- چکیده:
- چکیده انگلیسی: Total knee arthroplasty (TKA) is a rewarding procedure in patients with hemophilia and end stage knee hemophilic
arthropathy. However, this procedure might be associated with complications such as infection. There periprosthetic
joint infection in patients with hemophilia is very well known, though we are not aware of any previous report on Brucella
infection in this group of patients. Here, we reported a 28-year old man with Brucella infection of total knee replacement
who initially underwent a conservative treatment followed bya two-stage revision. We believe that this report will alert
physicians who work in endemic area for brucellosis to consider this in differential diagnosis and do the right intervention
at the right time.- انتشار مقاله: 13-11-1395

- چکیده:
- چکیده انگلیسی:
Background: This study has aimed to measure the patient dose in entire spine radiography by EOS system in comparison with the digital radiography.
Methods: EOS stereo-radiography was used for frontal and lateral view spine imaging in 41 patients in a prospective analytical study. A calibrated dose area product (DAP) meter was used for calibration of the DAP in EOS system. The accuracy and precision of the system was confirmed according to the acceptance testing. The same procedure was used for 18 patients referred for lumbar spine digital radiology (overall 36 images).
Results: Although radiation fields in the EOS were almost twice of that in digital radiology, and the average peak tube voltage (kVp), current supply to the tube (mA), and the average size and age of the patients referred for EOS imaging were greater than digital radiology, however, the average DAP in EOS was 1/5 of that in digital radiology system. Also, the average dose in the EOS was about 1/20 of that in digital radiology.
Conclusion: The patient dose in EOS imaging system was lower in comparison with digital radiology (1/20).- انتشار مقاله: 21-11-1395
