Severe Lateral Facet Patella Osteoarthritis Is Not Associated With Increased Failure at Mean 10 Years After Lateral Unicompartmental Knee Arthroplasty

BackgroundThe purpose of this study was to determine if severe lateral patella facet osteoarthritis was related to lower survivorship and poor patient-reported outcomes following fixed-bearing lateral unicompartmental knee arthroplasty (UKA). MethodsThere were 61 patients who underwent a fixed-bearing, nonrobotically assisted, lateral UKA between May 7, 2003 and December 18, 2019 and met the inclusion criteria. The patello-femoral joint was examined intraoperatively for chondral damage prior to UKA implantation. Severe lateral facet patella osteoarthritis (LFPOA) was defined as Outerbridge grades 3 or 4 changes on the lateral facet. All patients completed subjective functional outcomes questionnaires and a clinical examination at a minimum of 4 years following UKA. ResultsSevere LFPOA was identified in 28 (46%) patients. At a mean follow-up of 10.9 years, there were no statistically significant differences in any Knee Osteoarthritis Outcomes Score (KOOS) subscale or Kujala scores between patients who had and did not have severe LFPOA. There was no statistically significant difference in the percentage of patients who achieved Patient Acceptable Symptom State for the KOOS subscale scores between groups. Mean survival in patients who did not have severe LFPOA was 16.6 years (95% confidence interval, 15.4 to 17.7) compared to 18.9 years (95% confidence interval, 17.6 to 20.2) in patients who had severe LFPOA (P = 0.62). ConclusionsSevere LFPOA did not result in lower survival or inferior functional outcomes compared to patients who did not have severe osteoarthritis at an average 10-year follow-up after fixed-bearing lateral UKA.

Structural bone grafting with reverse shoulder arthroplasty for osteoarthritis with severe glenoid bone loss: outcomes using a long post

Severe posterior glenoid bone loss with glenohumeral osteoarthritis with an intact rotator cuff can be managed with reverse shoulder arthroplasty but requires lateralization and version correction to avoid potential complications, such as instability, notching and implant failure. Angled bone grafting with humeral head autograft can provide durable glenoid bone stock, but results have been mixed. The purpose of this study was to evaluate patient-reported and objective outcomes as well as complication and failure rates for patients who underwent angled humeral head autografting for severe retroversion. All patients who underwent a primary reverse shoulder arthroplasty with angled humeral head autograft and Stryker Tornier long central postbaseplate for severe glenoid bone loss in the setting of glenohumeral osteoarthritis with an intact rotator cuff at our institution between November 2018 and February of 2022 were identified. Individuals with a primary diagnosis of osteoarthritis and preoperative glenoid retroversion of ≥30° were included. Patients undergoing revision procedures, planned 2-stage arthroplasty were excluded. Differences in pre- and postoperative range of motion, as well as patient-reported outcomes were assessed. Intraoperative complications, postoperative complications, and re-operation rates were analyzed. A total of 24 shoulders in 23 patients (61% male), with a mean age of 65.6years were included. Average preoperative retroversion was 37.4° (range: 30°-51°). Mean follow-up was 2.9years (range: 2-4.3years). Significant improvements were found in flexion, abduction, and external rotation. Patient-reported subjective outcomes were excellent, with average American Shoulder and Elbow Surgeons score of 93.6 and average Subjective Shoulder Value score of 93.8%. Sixteen (67%) shoulders received postoperative computed tomography scans and all were found to have incorporated. Complications included one shoulder hematoma requiring incision and drainage without revision, and a post-traumatic fracture of the inferior glenoid screw at 11months, requiring revision reverse shoulder arthroplasty with bone grafting. No atraumatic catastrophic failures occurred due to component loosening. This study suggests that using angled humeral head bone grafting is a good solution for version correction in extreme posterior glenoid bone loss. Significant improvements are reported in range of motion, pain, and subjective functional scores, with excellent graft incorporation rates and a low complication profile at early follow-up. Further work should focus on gathering higher levels of evidence, detailed radiographic analyses, and exploring humeral head bone grafting for other indications.

Femoral tunnel length does not impact outcomes following ACL reconstruction using a single-bundle quadriceps tendon autograft: A systematic review.

To determine whether femoral tunnel length (FTL) affects clinical or functional outcomes following primary Anterior cruciate ligament reconstruction (ACLR) with single-bundle quadriceps tendon autograft, both with and without a patellar bone block. An electronic search of MEDLINE, EMBASE, and Cochrane databases was carried out via OVID. Data pertaining to study characteristics, patient demographics, surgical techniques, femoral tunnel length, and subjective/objective clinical outcomes was abstracted. Studies were stratified into two groups based on FTL; a short femoral tunnel (S-FT) group of ≤25 mm, and a long femoral tunnel (L-FT) group of >25 mm. There was a high degree of heterogeneity between studies, prohibiting meta-analysis. Seven studies comprising 368 total patients with a mean age of 30.3 years (range: 23.4-34 years) were included for analysis. The S-FT group included 126 patients and the L-FT group 242 patients. Both groups demonstrated statistically significant postoperative improvements across both subjective and objective clinical and functional outcomes. Average complication rates were 11.9% (range: 0%-29%) in the S-FT group and 4.5% (range: 1%-14%) in the L-FT group. Ranges of re-rupture rates were 0%-2% and 0%-3% for the S-FT and L-FT groups, respectively (n.s.). Both S-FT and L-FT groups demonstrated comparable postoperative outcomes following primary ACLR with single bundle quadriceps tendon autograft. There were slightly superior, although non-significant, outcomes reported with short femoral tunnel length, however, this may have been confounded by the variation in surgical technique used. IV.

Using Learning Videos to Improve Student Learning Outcomes in Social Sciences Subjects in Class VII of Jambi City Labor Middle School

Research objectives are the most important component in learning after the student component as a learning subject. In the educational context, the issue of goals is a question of the mission and vision of an educational institution itself. The research that the researcher carried out was in the form of Classroom Action Research (PTK). Implementation of this Classroom Action Research (PTK) utilizes Learning Videos, so that students are directly involved in learning activities. This shows an increase from the previous cycle, namely in cycle I the value of student learning outcomes in social studies subjects using learning videos was 63.25. The highest score obtained by students was 90 and the lowest score obtained was 35. 11 students met the KKM of 70, and 9 students did not meet the KKM. The percentage of students who reach the KKM is 55%. This means that cycle II has fulfilled the expected student learning outcome category of completeness, namely 100%. Based on the research results, it can be concluded that the achievement of student learning outcomes through learning videos in social studies subjects shows an increase in student learning outcomes.

Capitolunate versus Four-Corner Arthrodesis for Midcarpal Arthrosis

Abstract Background Midcarpal fusion is a procedure indicated for midcarpal arthrosis or instability, though the merits of fusing the triquetrohamate joint in addition to the capitolunate joint are not known. The purpose of this study was to compare capitolunate fusion with four-corner fusion with a null hypothesis that no differences would exist in outcomes. Methods A retrospective chart review of patients with midcarpal arthrosis who underwent midcarpal fusion between the years 2013 and 2023 was conducted. Patients were separated into groups according to fusion type. Demographics and methods of fixation were recorded. Outcomes evaluated included subjective outcomes, radiographic alignment, success of fusion, range of motion, strength, and complications. Results In total, 51 patients met inclusion criteria. Of these, 20 had capitolunate fusions and 31 had four-corner fusions. Staples were the most common form of fixation. Postoperative strength and range of motion were relatively preserved from preoperative levels in both groups. Both groups also had similar improvements in Disabilities of Arm, Shoulder, and Hand score. Capitolunate angles were not significantly different between groups; however, ulnar translocation was greater in the four-corner fusion group. Revision surgery was required in 10% of capitolunate fusions versus 29% of four-corner fusions, although this difference was not calculated to be significantly different. Conclusion Capitolunate fusion and four-corner fusion yielded comparable improvements with respect to clinical and radiographic outcomes. Fusing the triquetrohamate joint does not appear to enhance outcomes.

Feasibility of Dorsal Preservation Rhinoplasty for Hump Nose Reduction in Asian Population.

Background: Dorsal preservation rhinoplasty (DPR) has shown promise in Western populations for nasal hump reduction, but its feasibility and long-term outcomes in Asian individuals remain unexplored. Objective: To measure the feasibility, as well as the functional and aesthetic outcomes, of DPR in Asian hump noses and to determine its effectiveness in adaptation to the unique characteristics of the Asian demographic. Methods: A retrospective review analyzed patients who underwent primary DPR between April 2019 and November 2022 with a follow-up period of over 12 months. The study included patients whose photographs met the criteria. Surgical techniques, aesthetic measurements using anthropometric factors, and subjective outcomes were evaluated. Results: Of the 17 patients (11/17, 64.7% female), the mean age was 22.53 years (standard deviation [SD] 5.22 years). The median follow-up period was 36.90 months (range 13-61 months). Measurements from pre- and postoperative photographs showed a significant reduction in both nasofacial angle (7.76°, SD 4.30°) and rhinion angle (0.85°, SD 0.69°) (p < 0.0001). Patient-reported outcome scores with the Nasal Obstruction Symptom Evaluation scale decreased from 61.00 (SD 26.96) to 15.50 (SD 11.65), and Standardized Cosmesis and Health Nasal Outcomes Survey scores postoperatively were 10.90 (SD 7.71) overall, with the functional component at 3.50 (SD 2.64) and the aesthetic component at 7.40 (SD 6.24). No residual hump, recurrence of the hump, or complications were observed. Conclusion: In this study, the use of DPR techniques was effective and may support further development of the inclusion and exclusion criteria for its use in correcting the dorsal hump in Asian patients. Careful patient selection will be imperative to determine the ultimate indications for this technique.

Prior nonarthroplasty shoulder surgery and modifiable risk factors negatively affect patient outcomes after shoulder arthroplasty

BackgroundTotal shoulder arthroplasty frequently is performed in patients with a history of shoulder surgery. The purpose of this study was to evaluate clinical outcomes after primary shoulder arthroplasty in patients with a history of non-arthroplasty shoulder surgery, and whether certain modifiable risk factors (MRF) were negatively associated with final outcome measures. The secondary purpose was to determine if costs or complications were higher in patients with prior shoulder surgery. MethodsWe conducted a retrospective cohort study of all patients who underwent primary shoulder arthroplasty from January 2015 to December 2019 by one surgeon at one institution. Patients who received hemiarthroplasty were excluded. Univariate analysis was performed to assess the influence of prior shoulder surgery on costs, complications, and patient reported outcome measures (PROMs). Multivariable analysis was performed to determine if MRF negatively affected results, defined as anemia, malnutrition, obesity, uncontrolled diabetes, tobacco use, and opioid use. Results512 patients met inclusion criteria; 139 patients had at least one prior shoulder surgery. Patients with history of prior shoulder surgery were younger (65.2±9.3 years versus 70.7±9.1 years, p<0.001), more likely to be male (52.2% versus 47.8%, p=0.016), more likely to have smoking history (20.1% versus 10.5%, p=0.002), and borderline more likely to use preoperative opioids (47.5% versus 38.9%, p=0.078) while reporting significantly higher pain scores at final follow-up (VAS 1.7±2.4 versus 1.1±1.9, p=0.001) and lower PROMs (p≤0.017 for all). The final ASES score was independently negatively impacted by a history of prior surgery (β =-4.25 (-7.92, -0.56), p=0.024) and other non-modifiable factors including prosthesis type of reverse arthroplasty (β =-6.31, CI -10.02, -2.60, p=0.001), cardiac disease (β =-3.59, CI -7.12, -.0.07, p=0.046), and any complication (β =0.28, CI 0.19, 0.36, p<0.001). The final ASES score was negatively impacted by MRF including opioid use (β =-4.08, CI: -7.32, -0.84, p<0.001) and smoking status (β =-7.59, CI: -12.69, -2.49, p<0.001). Males had slightly higher final ASES scores (β = 3.79, CI 0.46, 7.11, p=0.026). Patients with prior surgery were more likely to have an intraoperative stress fracture [OR 4.6 (1.1, 19.5), p=0.038] and borderline more likely to have neurologic complication [OR 1.7 (1.0, 3.0), p=0.062] or any complication [OR 1.5 (1.0, 2.3), p=0.075]. ConclusionPatients with prior shoulder surgery were younger, more likely to be male, and more likely to have a history of tobacco use and opioid use. These patients experienced worse subjective clinical outcomes and were more likely to experience a complication.

A prospective, randomised, controlled, double blinded, cross-over study on the effect of a single session of pulsed electromagnetic field therapy on signs of hip osteoarthritis in dogs

BackgroundCanine coxofemoral joint osteoarthritis is a common, painful and debilitating condition. The objective of this study was to evaluate if any measurable changes in pain or lameness occurred in this patient group immediately after a single treatment with pulsed electromagnetic field therapy. Eight dogs with coxofemoral joint osteoarthritis presenting with signs of pain and lameness were prospectively recruited to this randomised, controlled, double blinded, cross-over study. Subjects attended the research facility on two occasions for one active and one placebo treatment with pulsed electromagnetic field therapy. The immediate effect of one pulsed electromagnetic field therapy treatment on pain and lameness was measured subjectively with the Helsinki Chronic Pain Index and Visual Analogue Scale and objectively using a pressure sensitive walkway.ResultsA statistically significant difference (P = 0.03) for change in stride length in the affected limb was recorded for subjects between the active and placebo treatments with pulsed electromagnetic field therapy. Within the active treatment results, there was a statistically significant change in the measurement for reach (P = 0.04) and stride length (P = 0.047) which got shorter in the affected limb post treatment. For the subjective outcome measures, there was no statistically significant difference between the active and placebo treatments for the evening of the treatment day or the next morning from pre-treatment values. Within the placebo treatment results a statistically significant change (improvement) was detected in Visual Analogue Score (P = 0.03) between pre-treatment and the next morning values.ConclusionsThe findings of this study do not show demonstrable improvement in owner assessed pain levels or temporospatial performance in dogs with coxofemoral joint osteoarthritis immediately after a single application of pulsed electromagnetic field therapy.

Visual performance, safety, and patient satisfaction after binocular clear lens extraction and trifocal intraocular lens implantation in Chinese presbyopic patients

BackgroundAddressing presbyopia in the aging population, particularly in non-cataractous patients, remains a challenge. This study evaluates the outcomes of refractive lens exchange (RLE) with AT LISA tri 839MP trifocal intraocular lens (IOL) implantation in a Chinese presbyopic population without cataracts.MethodsThe study included 164 eyes from 82 patients undergoing bilateral RLE at Peking Union Medical College Hospital. Comprehensive evaluations encompassed visual acuities, refraction, ocular aberrometry, and subjective outcomes via the VF-14 questionnaire. The focus was on postoperative visual performance, refractive outcomes, safety, objective optical quality, and patient satisfaction.Results100%, 90.2%, and 89.0% of patients achieved binocular UDVA, UNVA, and UIVA of logMAR 0.1 or better at 6 months postoperatively. 97.6% of eyes were within ± 1.00 D of emmetropia postoperatively. Optical quality assessments showed increases in modulation transfer function and Strehl ratios (p < 0.05). High-order aberrations decreased significantly (p < 0.05). Despite the high incidence of posterior capsule opacification (83.2%), managed with early Nd: YAG capsulotomy, no other severe complications were reported. Patient-reported outcomes indicated high satisfaction, with an average VF-14 score of 94.3 ± 10.2 and 93.5% achieving complete spectacle independence. Halo (66.2%) was the most commonly reported optical phenomena, followed by glare (18.2%), and starburst (7.8%) after surgery.ConclusionsBilateral RLE with trifocal IOLs in presbyopic patients without cataracts significantly improves visual acuity and reduces ocular aberrations in presbyopic patients. The procedure offers high patient satisfaction and spectacle independence, though it requires careful patient selection and management of expectations regarding potential photic phenomena.

Quality of life and tolerability of B-cell directed therapy of multiple sclerosis with ofatumumab in a patient-centered real-world observational study

IntroductionOfatumumab (Kesimpta®) is a subcutaneous CD20-targeting antibody approved in Germany in 2021 for the treatment of relapsing multiple sclerosis (RMS). After careful instruction, patients can administer the treatment themselves. We previously reported data of 101 patients (Klimas et al. in Nervenarzt 94:923–933, 2023). The objective of this longitudinal study is to explore the tolerability and acceptability of ofatumumab from a patient perspective over a follow up period of 6 months.MethodsIn this prospective observational real-world study, we report follow up data of 81 patients. We evaluated sociodemographic data, disease duration, duration and side effects of ofatumumab use, expanded disability status scale (EDSS), Beck Depression Inventory II (BDI-II), Short-Form 36 (SF-36), Fatigue Scale of Motor and Cognitive Functions (FSMC), and modified Multiple Sclerosis Functional Composite Test (MSFC). In addition, we asked for subjective treatment outcomes, such as impact on quality of life, walking distance, concentration, mood, medication adherence, fatigue and the subjective course of MS on a numerical rating scale (1 = very negative; 5 = very positive). Furthermore, treatment discontinuations were recorded.ResultsThe average duration of ofatumumab treatment was 10 months. In comparison to previous published data of our cohort, patients reported a significant increase in headache (10% up to 26%, p = 0.004) and limb pain (5% up to 26%, p < 0.001) as persistent side effects after the injections. More patients reported a very positive effect (p < 0.0001) on quality of life. 4 confirmed relapses occurred but no EDSS worsening, and no treatment discontinuations were documented during the observation period.DiscussionAs previously described, our prospective study indicates that patients have a good tolerability of ofatumumab, precisely because of the mild and few side effects at the first administration. However, the longer the observation period, the more headaches and limb pain occurred after the injections. Despite this, patients’ subjective quality of life improved. There were no discontinuations during the follow-up period, with the limitation of a high loss to follow-up.
