AbstractSeveral studies have reported improvement in knee pain following mesenchymal stem cell (MSC) injections for knee osteoarthritis (OA). We developed a novel 3D magnetic resonance imaging (MRI) analysis software program that provides “projected cartilage area ratios” for automatic detection of changes in cartilage amounts. The primary objective of this prospective interventional study was to compare alterations in the projected cartilage area ratio (thickness ≥ 1.5 mm) at the femoral posteromedial region between 30 weeks before and 30 weeks after synovial MSC injections. Secondary objectives were to assess the clinical scores and safety of MSC injections. Patients with OA who complained of knee pain underwent autologous synovial MSC injections into the knee at time 0 and again 15 weeks later. MRI examinations were performed at − 30, − 15, − 1, and 30 weeks. Patients showing < 3% decreases in the projected cartilage area ratio (thickness ≥ 1.5 mm) at the femoral the posteromedial region from − 30 weeks to − 15 weeks were excluded from the study. The Lysholm Knee Score, Knee Injury and Osteoarthritis Outcome Scale (KOOS), and Numerical Rating Scale (NRS) scores were evaluated at − 30, − 15, − 5, − 2, 0, 5, 10, 15, 20, 25, and 30 weeks. Five patients were excluded because 3D MRI analysis showed no cartilage loss at − 15 weeks. Ultimately, eight OA patients underwent MSC injections. The projected cartilage area ratio significantly decreased by 0.07 in the 30 weeks before MSC injections (p = 0.01), but no further decreases occurred in the 30 weeks after MSC injections. The projected cartilage area ratio at the femoral posteromedial region showed a significant difference between 30 weeks before and 30 weeks after MSC injections. The Lysholm Knee Score, KOOS, and NRS values improved significantly after the injections. MSC injection could not be ruled out as the cause of two adverse events: transient knee pain and itching in both hands. Fully automatic 3D MRI analysis showed that synovial MSC injections suppressed cartilage loss in patients with progressive OA.Trial registration: Intraarticular injections of synovial stem cells for osteoarthritis of the knee (Number UMIN 000026732).

Introduction: Limits of movement in knees is one of the most common complications following trauma and surgery. With early diagnosis and appropriate treatment choices, knee replacement and performance improvement are expected in many patients. However, limits of movement in knees is unpleasant and should be corrected as soon as possible. In this study, we decided to evaluate the results of arthroscopic release in motion limits of knees. Methods: This was a descriptive cross-sectional study.14 patients who referred to the Shahid Sadoughi Hospital of Yazd from 2014 to 2016 and diagnosed with knee limitation (flexion or extension restriction of more than 10 degrees) were selected. Patients were undergone arthroscopic release and followed-up for 6 months. Lysholm knee score, degrees of flexion and extension, and patient satisfaction were evaluated. The results were analyzed by SPSS-18 and statistical tests Paired T-test as well as Spearman correlation. Results: The mean age of the patients was 28.92±10.99 years. The most common type of trauma in the patients was femoral distal fracture (46.7%). The frequency of the patients' satisfaction with arthroscopy was as followed: 50% (7 patients), had moderate satisfaction, 28.6% (4 ones), high satisfaction, and 21.4% (3 ones) had low satisfaction.The mean difference in Lysholm Knee Score, improvement in degree of extension, improvement in degree of flexion and pain score before and after arthroscopy were 26.21±14.11,64.78±26.13,3.57±2.92 and 4.13±1.65,respectively.There was a significant difference between the mean values of these factors before and after arthroscopy. Conclusion: According to the results obtained, we can conclude that arthroscopic release is an effective and low-complication method in motion limits of knees.

The umbilical cord-mesenchymal stem cells (UC-MSC) has been shown to improve the viability of degenerated chondrocytes in knee osteoarthritis (KOA) in cellular level. Additional somatotropin injection also shown clinical improvement in patients. The present trial is conducted to assess the efficacy of umbilical cord mesenchymal stem cells (UC-MSC) in comparison to somatotropin and hyaluronic acid (HA) injection to treat and slow the progression of knee osteoarthritis. Methods: This study was conducted from January 2016 to April 2018 in Cipto Mangunkusumo General Hospital. A total of 28 knees from 15 patients with early KOA Kellgren Lawrence I-II were randomized into three groups. Group A was treated with 1x106 units of intra-articular UC-MSCs + 2 ml HA followed with 2 consecutive weeks of HA injection; group B was treated with the same dose of HA with additional 8 IU of Somatotropin; group C was treated as control. The International Knee Documentation Committee (IKDC) score, The Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), visual analogue score (VAS), were assessed on the 1st and 3rd month, then every 3rd month until 12 months. Cartilage evaluation using MRI cartigram were performed at pre-implantation, and after the 6th and 12th month after implantation Results: General improvement were observed in all groups after 6 and 12 months. The IKDC score improved significantly among groups after 12 months (69.43 [48.3-89.66], 79.31 [51.72-90.08], and 75.9 [67.82-97.7] in group A, B, and C, respectively, p =0.005). We did not find a significant difference between groups in VAS and WOMAC results. However, we observed a medial T2 improvement in group A (39.55 [32.65-67.85] initially and 45.64 [38.12-70.65] 12 months after implantation). Conclusion: Injection of UC-MSC could improve knee function and cartilage profile in early KOA. However, further multicenter studies with larger samples are required to investigate the efficacy of such treatment for treating knee osteoarthritis.

PurposeRtsa-byugs, a massage oil from Bhutan, is a traditional herbal formula known for its anti-inflammatory properties and used in osteoarthritis treatment. This study investigates the efficacy of rtsa-byugs vs diclofenacgel in relieving knee pain in osteoarthritis patients.Design/methodology/approachA single-blind, randomized controlled trial was conducted amongst osteoarthritis knee patients at an orthopedic outpatient department of Thammasat University Hospital. Participants were randomly allocated to the rtsa-byugs (N = 31) or the Diclofenac gel (N = 31) group. Primary outcomes were assessed by the knee injury and osteoarthritis outcome scores (KOOS), visual analog scale (VAS) and goniometer at day 0, 1, 3, 7.Findings62 participants completed the study. The result of the KOOS scores demonstrated a significant improvement of symptoms at the end of the study in both treatment groups. Improvement of symptoms, pain, daily life living, sport and recreational score and quality of life assessment showed a significant difference from baseline (p < 0.001) within both groups. The quality of life score for the rtsa-byugs group increased significantly on day 3 and 7. The VAS score in both groups decreased with a significant difference from baseline to day 7. The mean value of extension of angle measurement was decreased in day 7, and the mean of flexion score increased in both groups when compared with the baseline.Research limitations/implicationsThe duration of the study was very limited and included a small sample consisting of men and women.Originality/valueRtsa-byugs is safe and effective in relieving pain from osteoarthritis of the knee and can be used as an alternative treatment for knee osteoarthritis.

In recent years, there is a growing interest in the application of regenerative medicine methods in the treatment of degenerative lesions of the musculoskeletal system. Gonarthrosis is one of the most common reasons for patients to visit to orthopedic traumatologists. The purpose of the study was to evaluate the quality of life in patients with gonarthrosis at different stages after application of leukocyte-rich platelet-rich plasma (LR-PRP) and leukocyte-poor platelet-rich plasma (LP-PRP). Materials and methods. The results of the treatment of 48 patients with gonarthrosis stages 1-3 according to Kellgren-Lawrence after intra-articularly injection of LR-PRP or LP-PRP were compared. The quality of life questionnaires were used: visual analogue scale (VAS), Lysholm Knee Score (LKS) and Oxford Knee Score (OKS) before treatment, after the first injection, every 2 weeks before the end of treatment and every 3 months for 1 year. Results. Evaluation of the treatment results obtained at stages 1 and 2 of gonarthrosis showed a positive result for both groups of patients during 12 months of follow-up and at stage 3 a significant improvement was achieved for up to 6 months. There was no significant difference between the results of LR-PRP and LP-PRP for 9-12 months. When using LP-PRP, the dynamics of quality of life during the year was smoother and more gradual, without periods of regression, while for LR-PRP there was a clear significant short-term reduction in the treatment effect for about 6 months compared to both baseline and values of the previous period at 1 and 2 stages gonarthrosis with further improvement and a stable positive effect for up to 12 months. Conclusions. The application of platelet-rich plasma improved the quality of life for 12 months in patients with stage 1-2 gonarthrosis and for 6 months at stage 3. The obtained positive results substantiate the need for further research to determine the prospects for the application of platelet-rich plasma in the complex treatment of knee osteoarthritis compared to other methods.

Background: Pain is the most common symptom for presentation to an orthopaedic practice and orthopedists rank 4th among top prescribers of opiates. Pain acuity, etiology and severity have been published as guiding factors for pain assessment and management. In an attempt to address the underassessment and undertreatment of pain, pain was even considered the 5th vital sign for a period of time. Assessment of pain using validated severity assessment instruments including the Visual Analogue Scale and the Wong-Baker FACES® Scale, is common in orthopaedic practices. The purpose of this study is to evaluate the validity and sensitivity of self-reported pain assessment tools administered to pediatric and adolescent patients presenting with a primary complaint of knee pain. Methods: A retrospective review of 211 patients with a primary complaint of knee pain in a single practice over a nine-month period was completed. Medical records were reviewed for demographics, sport, laterality, symptoms, and factors described as influencing the pain. Prior to orthopaedic evaluation, patients were given an electronic tablet to complete patient reported outcomes measures and the visual analog scale (VAS). Patients were asked, electronically, “Do you have pain today?” and to verbally rate the pain using a Wong-Baker FACES® Pain Rating Scale (FACES). The FACES scale, typically a 0-5 rating, was normalized to a 0-10 scale for comparison to both the VAS and the pain component of the pedi-IKDC (Pain-pIKDC). A Pearson’s correlation was used to compare the VAS and the Pain-pIKDC with the FACES scores to determine validity. A paired t-test was used to identify differences between the three measures. Results: Of the 211 subjects, 112 were females and 99 were males, with a mean age of 13.9 years (range 7-18). 82% of patients reported presenting for pain due to a specific injury and not of spontaneous origin. The mean FACES score was 1.26 (normalized to 2.52) with a median score of 0. Compared to the FACES, the mean VAS was 4.22 (p<0.001) and Pain-pIKDC was 3.66 (p<0.001) noted to be both a statistically and clinically significant difference. When comparing the FACES to VAS, a weak correlation was noted (0.360, p<0.001). A stronger correlation was noted between the VAS and the Pain-pIKDC (0.752, p<0.001). 66.4% of patients reported no pain on the FACES but reported pain >1 on the Pedi-IKDC. 80.5% of patients reported no pain on FACES but pain of >1 on the VAS. Only 12.2% on VAS and 16.2% on Pain-pIKDC reported no pain . For both the VAS and Pain-pIKDC, the sensitivity of detecting “no pain” is low at 19.2% and 30.2% respectively. Conclusion: Though pain is widely accepted as an important factor for patient care management, clinicians should be aware that self-reported pain assessment tools in pediatrics and adolescents, without verbal confirmation, may inflate reported pain intensity and lead to possible overtreatment.

Abstract Objective The aim of the study is to observe the effect of post-stroke depression on functional outcomes during inpatient rehabilitation. Patients and Methods The design involved is prospective observational study. The location involved is Neurological Rehabilitation unit in a tertiary care university hospital. The study period ranges from October 2019 to April 2020. The participants involved are the patients with first ever stroke, male and female with age ≥18 years and duration less than 1 year. All participants were assessed at admission and after 14 sessions of inpatient rehabilitation by depression subscale of Hospital Anxiety and Depression Scale (HADS-D) and Hamilton Depression Rating Scale (HDRS). The stroke outcomes measures used were: Barthel Index (BI), Scandinavian Stroke Scale (SSS), and Modified Rankin Scale (MRS). Results There are a total of 30 participants (18 males) with median stroke duration of 90 days. The median age of the patients was 58 years. Sixteen patients had ischemic and 14 had hemorrhagic stroke. Out of these, 57% (n = 17) had symptoms of depression (HADS-D >7). Participants in both groups (with and without depression) showed improvement in all the functional outcome measures (BI, SSS, MRS) at the time of discharge as compared with admission scores. The changes in the outcome measures were statistically significant within groups (p < 0.05) but not significant between the groups (p > 0.05). Conclusion The post-stroke depression is common among stroke survivors of less than 1 year duration. There was no significant difference in the functional outcomes between stroke patients with depression and those without depression with inpatient rehabilitation program.

AbstractWe investigated the efficacy of donepezil for mild cognitive impairment in Parkinson’s disease (PD-MCI). This was a prospective, non-randomized, open-label, two-arm study. Eighty PD-MCI patients were assigned to either a treatment or control group. The treatment group received donepezil for 48 weeks. The primary outcome measures were the Korean version of Mini-Mental State Exam and Montreal Cognitive Assessment scores. Secondary outcome measures were the Clinical Dementia Rating, Unified Parkinson’s Disease Rating Scale part III, Clinical Global Impression scores. Progression of dementia was assessed at 48-week. Comprehensive neuropsychological tests and electroencephalography (EEG) were performed at baseline and after 48 weeks. The spectral power ratio of the theta to beta2 band (TB2R) in the electroencephalogram was analyzed. There was no significant difference in the primary and secondary outcome measures between the two groups. However, the treatment group showed a significant decrease in TB2R at bilateral frontotemporoparietal channels compared to the control group. Although we could not demonstrate improvements in the cognitive functions, donepezil treatment had a modulatory effect on the EEG in PD-MCI patients. EEG might be a sensitive biomarker for detecting changes in PD-MCI after donepezil treatment.

Abstract Background The ongoing COVID-19 pandemic has disrupted the surgical training of residents. There is a real concern that trainees will not be able to meet their training requirements. Low-fidelity surgical simulation appears to be an alternative for surgical training. The educational benefits of repeating ossiculoplasty simulations under a microscope have never been evaluated. With this study we aimed to evaluate the differences in performance scores and on a global rating scale before and after training on an ossiculoplasty simulator. Methods In this quasi-experimental, prospective, single-centre, before-after study with blinded rater evaluation, residents performed five microscopic ossiculoplasty tasks with a difficulty gradient (sliding beads onto rods, the insertion of a partial prosthesis, the insertion of a total prosthesis, and the insertion of a stapedotomy piston under microscopic or endoscopic surgery) before and after training on the same simulator. Performance scores were defined for each task, and total performance scores (score/min) were calculated. All data were collected prospectively. Results Six out of seven intermediate residents and 8/9 novices strongly agreed that the simulator was an effective training device and should be included in the ENT residency program. The mean effect of training was a significant increase in the total performance score (+ 0.52 points/min, [95 % CI, 0.40–0.64], p < 0.001), without a significant difference between novice and intermediate residents. Conclusions This preliminary study shows that techniques for middle-ear surgery can be acquired using a simulator, avoiding any risk for patients, even under lockdown measures.
