Beyond one step: unveiling optimal approach for bilateral knee arthroplasty - a comprehensive meta-analysis.

BACKGROUND: Total knee arthroplasty (TKA) is an efficient and common procedure used to treat advanced osteoarthritis of the knee. Geriatric patients make up the majority of TKA patients. For the surgical management of bilateral knee arthritis, there is still debate regarding whether to do a simultaneous or staged TKA. We through this study have gathered data and aimed to assess the safety of simultaneous bilateral TKA in patients. MATERIALS AND METHODS: We conducted a study according to the PRISMA guidelines by searching through various databases for the following search terms: total knee arthroplasty (TKA), complications following TKA, bilateral TKA, and bilateral vs. unilateral TKA. The search included case series and clinical trials and excluded review articles, yielding 24 articles from the original search. We extracted data upon the outcomes in patients undergoing simultaneous bilateral TKA. We performed additional bias assessments to validate our search algorithm and results. RESULTS: One hundred and three published articles were identified, and twenty-four that included a total of 2, 18,385 patients were included in the meta-analysis. 93,074 patients underwent simultaneous bilateral TKA and 125,311 patients underwent staged bilateral TKA. Simultaneous bilateral TKA was associated with significantly increased mortality rate (P < 0.00001, Odd's ratio [OR] 1.86, 95% Confidence interval [CI] 1.53-2.26), increased incidence of pulmonary embolism (P < 0.00001, OR 1.58, 95% CI 1.30-1.91), deep venous thrombosis (P < 0.00001, OR 1.31, 95% CI 1.17-1.46), and neurological complications (P < 0.002, OR 1.44, 95% CI 1.14-1.82). There were no significant differences in cardiac complications between both the procedures (P = 0.60, OR 0.93, 95% CI 0.70-1.23). CONCLUSION: Staged bilateral TKA is associated with less complication rates as compared to simultaneous bilateral TKA. Hence, patients should be counselled and selected based on the risks respective to each strategy.

Platelet-rich plasma in chronic Achilles tendinopathy.

INTRODUCTION: Achilles tendinopathy [AT] is a functional problem characterised by swelling and pain above the Achilles tendon insertion region. In individuals with AT, PRP or platelet-rich plasma can be used as an alternative modality of treatment with an aim to lessen the discomfort and enhance functional recovery. We assessed the available data supporting the effectiveness of PRP in treating chronic AT. MATERIALS AND METHODS: We did a literature search for randomised controlled trials [RCTs] that contrasted the effectiveness of PRP with that of eccentric exercise and placebo injections as treatment for AT in databases such as the Cochrane Library, Web of Science, PubMed, and EMBASE. The Visual analogue scale [VAS] score, Victorian Institute of Sports Assessment-Achilles [VISA-A] score, and Achilles tendon thickness were used to measure the results. We used the RevMan 5.3.5 software for statistical analysis. RESULTS: We included five RCTs in this meta-analysis. There was no significant difference in the VISA-A between the PRP and placebo groups at 12 weeks, 24 weeks and 1 year after treatment. However, at 6 weeks after treatment, PRP exhibited better efficacy than the placebo treatment. Two studies in our meta-analysis included VAS scores and tendon thickness. There was no significant difference in VAS scores at 6 weeks and 24 weeks after treatment. However, VAS scores at 12 weeks and tendon thickness were significantly different. CONCLUSION: PRP injection is an effective treatment for chronic AT. It has a unique potential for increasing function and reducing discomfort in AT patients.

Use of a Video Laryngoscope to Reduce Complications of Transesophageal Echocardiography Probe Insertion: A Multicenter Randomized Study.

OBJECTIVE: The objective of this multicenter study was to test the hypothesis of whether the use of a video laryngoscope (VL) reduces complications related to transesophageal echocardiography (TEE) probe insertion. DESIGN: A multicenter randomized control study. SETTING: At 5 tertiary care level hospitals. PARTICIPANTS: Three hundred sixty-three adult patients undergoing elective cardiac surgery. INTERVENTIONS: The patients were randomized into 2 groups-the conventional group (C group; n = 177) and the VL group (n = 186) for TEE probe insertion. MEASUREMENTS AND MAIN RESULTS: The primary endpoint of the study was the incidence of oropharyngeal injury, which was defined as blood at the tip of the TEE probe at the end of surgery and/or evidence of injury on VL examination at the end of surgery. The secondary endpoints of the study were the number of attempts required for successful TEE probe insertion and the relation between the esophageal inlet and the larynx. There was a higher incidence of injuries in the C group (n = 26; 14.7%) compared to the VL group (n = 14; 7.5%; p = 0.029). The number of attempts for probe insertion was significantly lower in the VL group (p = 0.0023). The most common relation between the esophageal inlet and the larynx was posterolateral (n = 88; 47%), followed by posterior (n = 77; 41%) and lateral (n = 21;12%). CONCLUSION: The use of VL was associated with a lesser incidence of injury compared to the conventional technique, and its use for this purpose is recommended. The use of VL for probe insertion resulted in fewer attempts compared with the conventional technique. Significant variations do exist in the relation between the esophageal inlet and the larynx, and direct visualization with VL may contribute to better safety.

Normative Transesophageal Echocardiographic Values of Cardiac Structures in the Indian Population-Indian Normative TEE Measurements (INTEEM) Study.

OBJECTIVES: Information on normative reference values for cardiac structures is critical for the accurate application of echocardiography for guiding clinical decision-making. Many studies using transthoracic echocardiography (TTE) have shown that Indians have smaller diameters of various cardiac structures. There are no normative studies for transesophageal echocardiography (TEE). The authors observed dimensions of various cardiac structures in healthy Indian patients under general anesthesia using TEE and compared them with existing guidelines from non-Indian data. DESIGN: The Indian Normative TEE Measurements study was a multicenter, prospective observational study conducted in India. SETTING: Operating rooms for noncardiac surgeries in tertiary care-level hospitals. PARTICIPANTS: Adult patients undergoing noncardiac surgery who were free from any cardiac, respiratory, and renal diseases and had no contraindications for TEE. INTERVENTIONS: After inducing general anesthesia and achieving stable hemodynamic conditions, a comprehensive TEE examination was performed and various measurements were made. MEASUREMENTS AND MAIN RESULTS: For each of the 83 patients undergoing noncardiac surgery, 39 various measurements for left ventricle, right ventricle, both atria, and all valves were made. This included diameters and functional parameters. They were analyzed in a vendor-neutral software off-line. The absolute values of many of the measurements were higher in men, but when indexed to body surface area (BSA) they were similar in both sexes. The values were lower than most of the Western data but matched previous Indian studies using TTE. CONCLUSIONS: The authors present normative values of various echocardiographic parameters using TEE. Because of its variations, it is recommended to use India-specific data to make decisions in Indian patients. It may be prudent to use BSA-indexed values during decision-making.

Comparing the efficacy of intravenous or intra-articular tranexamic acid in reducing blood loss in simultaneous bilateral knee replacement surgery without the use of tourniquet.

PURPOSE: To compare the effect of intravenous or intra-articular route of administration of tranexamic acid in reducing the blood loss in simultaneous bilateral total knee replacement surgeries performed without the use of tourniquets. METHODS: Prospective cohort study of 30 consecutive patients grouped into two groups; Group 1: intravenous group and group 2: intra-articular group. Two outcome measures were studied; mean drop in post-operative haemoglobin and need for blood transfusion in both groups. RESULTS: No significant difference in mean drop of haemoglobin and need for blood transfusion in both groups. CONCLUSION: Route of administration of tranexamic acid does not influence on the mean drop of haemoglobin and need for blood transfusion in simultaneous bilateral total knee replacement surgeries performed without the use of tourniquet.

ASSIST - Patient satisfaction survey in postoperative pain management from Indian subcontinent.

INTRODUCTION: To compare pain scores at rest and ambulation and to assess patient satisfaction between the different modalities of pain management at different time points after surgery. SETTINGS AND DESIGN: The ASSIST (Patient Satisfaction Survey: Pain Management) was an investigator-initiated, prospective, multicenter survey conducted among 1046 postoperative patients from India. MATERIAL AND METHODS: Pain scores, patient's and caregiver's satisfaction toward postoperative pain treatment, and overall pain management at the hospital were captured at three different time points through a specially designed questionnaire. The survey assessed if the presence of acute pain services (APSs) leads to better pain scores and patient satisfaction scores. STATISTICAL ANALYSIS: One-way ANOVA was used to evaluate the statistical significance between different modalities of pain management, and paired t-test was used to compare pain and patient satisfaction scores between the APS and non-APS groups. RESULTS: The results indicated that about 88.4% of patients reported postoperative pain during the first 24 h after surgery. The mean pain score at rest on a scale of 1-10 was 2.3 ± 1.8 during the first 24 h after surgery and 1.1 ± 1.5 at 72 h; the patient satisfaction was 7.9/10. Significant pain relief from all pain treatment was reported by patients in the non-APS group (81.6%) compared with those in the APS (77.8%) group (P < 0.0016). CONCLUSION: This investigator-initiated survey from the Indian subcontinent demonstrates that current standards of care in postoperative pain management remain suboptimal and that APS service, wherever it exists, is yet to reach its full potential.

Musculoskeletal trauma and all-cause mortality in India: a multicentre prospective cohort study.

BACKGROUND: There is little data in low-income and middle-income countries (LMICs) quantifying the burden of fractures and describing current practices. The aim of the study was describe the severity of musculoskeletal injuries in LMICS and identify modifiable factors that predict subsequent early all-cause mortality. METHODS: We did a multicentre, prospective, observational study of patients who presented to 14 hospitals across India for musculoskeletal trauma (fractures or dislocations). Patients were recruited during an 8-week period, between November, 2011, and June, 2012, and were followed for 30-days or hospital discharge, whichever occurred first. Primary outcome was all-cause mortality with secondary outcomes of reoperation and infection. Logistic regression analyses were conducted to identify factors associated with all-cause mortality. FINDINGS: We enrolled 4822 patients, but restricted analyses to 4612 (96%) patients who had complete follow-up. The majority (56·2% younger than 40 years old) of trauma patients were young (mean age 40·9 years [SD 16·9]) and 3148 (68%) were men. 2344 (518%) patients sustained trauma as a result of a road traffic accident. The most common musculoskeletal injury was a fracture (4514 [98%]) and 707 patients (15%) incurred an open fracture. Less than a third of musculoskeletal trauma patients (1374 [29%]) were transported to hospital by ambulance, and one in six patients (18%) arrived at the hospital later than 24 h after sustaining their injury. Over a third (239 [35%] of 707) of open fractures were definitively stabilised later than 24 h. 30-day mortality was 1·7% (95% CI 1·4-2·2) for all patients and 2·1% (95% CI 1·5-2·7) among road traffic victims (p=0·005). Musculoskeletal trauma severity including the number of fractures (3·1 [95% CI 2·4-3·9]) and presence of an open fracture (2·1 [95% CI 1·2-3·4]) significantly increased the odds of all-cause mortality. INTERPRETATION: Musculoskeletal trauma severity, particularly road related, is a key predictor of subsequent mortality. Improvement in road safety policies, and improvements in access to emergency medical services and timely orthopaedic care are critical to mitigate the burden of injury worldwide.

A ballooning heart-giant left ventricular apical pseudoaneurysm presenting as congestive heart failure.

Left ventricular (LV) pseudo aneurysm is a contained rupture of ventricular wall by adherent pericardium or scar tissue. We present a case of a 70 year-old male presented with exertional dyspnea for 2 months and found to have giant LV pseudo aneurysm on transthoracic echocardiogram, cardiac MRI and angiogram. To our knowledge such a large pseudo aneurysm involving LV apex and presenting as congestive heart failure is the first case in literature.

A study to compare the efficacy of corticosteroid therapy with platelet-rich plasma therapy in recalcitrant plantar fasciitis: a preliminary report.

BACKGROUND: Plantar fasciitis is one of the commonest, and most frustrating, foot ailments seen in a regular orthopaedic clinic. There are a number of modalities available to treat this condition, of which corticosteroid injection is, perhaps, the most popular. However, recent years have seen an increased interest in the use of platelet-rich plasma (PRP) injections in various clinical situations such as plantar fasciitis. METHODS: We undertook a prospective non-randomized study to compare the efficacy of traditional corticosteroid injection (Steroid group) to PRP injection (PRP group), in a cohort of patients. RESULTS: We studied both groups of patients before and after the injections using Visual Analogue Score (VAS), the Foot & Ankle Disability Index (FADI) and American Foot and Ankle Score (AFAS). Our study confirms that there is significant clinical improvement in PRP group at three months after the injection. CONCLUSION: The use of PRP injection can be an attractive alternative in the treatment of disabling, recalcitrant plantar fasciitis. STUDY DESIGN: Cohort study. LEVEL OF CLINICAL EVIDENCE: Level 3.

Emerging intra-articular causes of groin pain in athletes.

Groin pain remains one of the most poorly understood conditions in clinical sports medicine. It may be caused by either extra-articular or intra-articular conditions. While extra-articular causes have been extensively studied and reasonably understood, a number of elusive intra-articular causes are emerging, many of which were previously unknown and therefore undiagnosed, leading to premature ending of many competitive careers. This article makes an attempt to look at various, elusive intra-articular causes of groin pain in athletes. This article also analyses the currently available evidence on trends in diagnosis and treatment for these conditions.

Effectiveness of platelet-rich plasma in partial-thickness rotator cuff tears: a systematic review.

IMPORTANCE: Partial-thickness rotator cuff tears (PTRCTs) commonly affect overhead athletes, leading to a decline in sports performance. Platelet-rich plasma (PRP) is being explored as an alternative treatment modality for individuals with PTRCTs to reduce discomfort and enhance functional recovery. We conducted a systematic review study of randomized controlled clinical trials to determine the effectiveness of PRP in treating PTRCTs. AIM: To determine the effectiveness of PRP in treating PTRCTs. EVIDENCE REVIEW: We conducted a comprehensive literature search for randomized controlled trials (RCTs) that compared the effectiveness of PRP with eccentric exercise and placebo injections as treatments for PTRCTs. We searched databases such as the Cochrane Library, Web of Science, PubMed, and EMBASE. The visual analog scale (VAS) score, American Shoulder and Elbow Surgeon (ASES) score, and Constant-Murley Score (CMS) was utilized as an outcome measure. Statistical analysis was performed using RevMan 5.3 software. FINDINGS: Our meta-analysis included 12 studies involving 762 patients. At six weeks post-treatment, the PRP group had significantly higher VAS scores compared to the control group, indicating improvement (standard mean difference (SMD): -2.04 [95% confidence interval (CI): -4.00 to -0.08], I2 â€‹= â€‹97%, P-value â€‹= â€‹0.04). Patients who received PRP showed statistically significant improvements in VAS scores at 3 months and 6 months follow-up (SMD, -1.78 [95% CI: -3.03 to -0.52], I2 â€‹= â€‹96%, P-value â€‹= â€‹0.005) (SMD: -2.26 [95% CI: -3.77 to -0.76], I2 â€‹= â€‹97%, P-value â€‹= â€‹0.003). A statistically significant difference was also observed in VAS scores at the long-term 1-year follow-up (SMD: -2.27 [95% CI: -4.07 to -0.47]; I2 â€‹= â€‹98%; P-value â€‹= â€‹0.031). There were statistically significant differences in ASES scores and CMS scores in the short-term (SMD: 1.21 [95% CI: 0.19 to 2.24], I2 â€‹= â€‹96%, P-value â€‹= â€‹0.02) (SMD, 2.01 [95% CI: 0.14 to 3.88], I2 â€‹= â€‹97%, P-value â€‹= â€‹0.04). However, in the long-term ASES and CMS scores did not show any statistical significance (SMD: 2.06 [95% CI: -0.54 to 4.65], I2 â€‹= â€‹99%, P-value â€‹= â€‹0.12) (SMD: 4.36 [95% CI: -5.48 to 14.21], I2 â€‹= â€‹99%, P-value â€‹= â€‹0.39). CONCLUSIONS AND RELEVANCE: Our findings suggest that PRP treatment is effective in reducing pain for individuals with PTRCTs, providing benefits in the short and long term. However, its impact on functional recovery appears somewhat constrained and doesn't endure over time. Additionally, significant heterogeneity exists among studies, encompassing variations in PRP composition and control group treatments. Consequently, we conclude that compelling evidence for symptom improvement in PTRCT patients following PRP treatment remains elusive. LEVEL OF EVIDENCE: Level I.

Pulmonary Embolism as a Potential Trigger for Takotsubo Cardiomyopathy.

We present a case of an 83-year-old female who presented to the emergency department because of poor oral intake and dizziness. Initial assessment revealed a diagnosis of pulmonary embolism (PE). However, further investigation revealed coexisting takotsubo cardiomyopathy (TCM), a rare but critical finding. This case highlights a possible causative connection between clinically non-significant PE and TCM. Additionally, it emphasizes the diagnostic challenges posed by atypical symptoms and unremarkable medical history, which can lead to delayed diagnosis in such cases.

Comparison of Time Taken in Conventional versus Active Robotic-Assisted Total Knee Arthroplasty.

Background: Computer- and robotic-assisted total knee replacement procedures have been shown to improve the accuracy of the implant size. It also allows dynamic confirmation of the implant and limb alignment during total knee arthroplasty (TKA). The major inhibition of the arthroplasty surgeon in adapting to the robotic-assisted TKA (RA-TKA) is the extra time spent during the registration process and milling of the bone with the robot. The aim of the study was to ascertain the extra time spent during these 2 steps as compared to the conventional TKA (C-TKA). Methods: It is a prospective study involving 30 patients each in the conventional TKA and RA-TKA operated by the same surgical team. The patients were given a choice between the C-TKA and RA-TKA and consecutive 30 cases in each group were studied by an independent observer. In the C-TKA group, the time for the application of appropriate zigs and execution of the bone cuts and soft-tissue release was recorded whereas in the RA-TKA group, the time taken for fixation of the tibial and femoral arrays and bone registration and bone milling with robot and required soft-tissue release was measured. Results: The preoperative patient characteristics were the same in both groups. The time taken in the C-TKA and RA-TKA groups was 24.77 ± 1.92 minutes and 25.03 ± 3.27 minutes, respectively, which is statistically insignificant (p = 0.709). Conclusions: The study findings show that RA-TKA does not take additional time than C-TKA.

Analysis of robot-specific operative time and surgical team anxiety level and its effect on alignment during robot-assisted TKA.

Adapting to robotic-assisted (RA) total knee arthroplasty (TKA) is hindered by the surgeon's fear of extra time. The main purpose of this study was to determine the robot's operative time, and the secondary goals were to assess the surgical team's anxiety, implant location and size, and limb alignment. From February to April 2022, 40 participants participated in prospective research. The study included primary Cuvis joint active RA-TKA patients for end-stage arthritis, but conversion of unicompartmental knee arthroplasty to TKA, and patients with prior knee surgery were excluded. The active RA-TKA surgical time included surgeon-dependent and surgeon-independent/active robot time. The surgeon's anxiety was measured using the state-trait anxiety inventory (STAI). The implant size/position and limb alignment were checked by post-operative weight-bearing lateral, anteroposterior, and full-length scanograms. Operative time specifically related to active RA-TKA was higher in the first 10 cases as against 10-20, 20-30 and 30-40 cases which was observed to lower from cohort 2. A similar trend was observed for the surgical team's anxiety levels which seem to lower from cohort 2 (case 10-20). Cumulative experience of active RA-TKA showed no effect on the precision of implant alignment/ size, limb alignment and complications. The study showed progressive improvement in the surgical anxiety scores and reduction in operating time indicating the proficiency gained by the surgical team. Further no learning curve was involved in achieving the implant positioning and sizing, limb alignment with the absence of complications.

Clinical Manifestations and Outcomes of Ocular Graft Versus Host Disease following Allogeneic Stem Cell Transplantation.

Purpose: To evaluate clinical presentation of chronic ocular graft-versus-host disease (GVHD), laterality of presentation, and longitudinal changes in patients undergoing allogeneic stem cell transplantation. Methods: This is a retrospective longitudinal analysis of 60 eyes from 30 patients who had undergone hematopoietic stem cell transplantation. Demographic characteristics, clinical history, comorbidities, and other organ involvements were taken into account for analysis. We also undertook complete evaluation of the eyes, including cornea and anterior segment, posterior segment, Schirmer test, tear break-up time, ocular surface disease index, and intraocular pressure. Results: The mean age of the patients was 34.3 ± 11 years. The mean time for the diagnosis of ocular GVHD was 232.8 days (95% CI: 153.6, 311.9). The common findings at the first visit were bilateral blepharitis (n = 5, 17%), meibomitis (n = 4, 13%), and conjunctival congestion (n = 3, 10%). While bilateral cataract was present in one (3%) patient at the first visit, at 18 months, five (17%) patients had bilateral cataract and one (3%) patient had unilateral cataract. Grade 1 (n = 17), grade 2 (n = 9), and grade 3 (n = 4) superficial punctate epithelial erosions (SPEEs) were also observed at the first visit. However, SPEEs were seen in only 11 eyes at 18 months; all of these cases were grade 1 SPEEs. Long-term findings included cataract, telangiectasia, blepharospasm, conjunctival congestion, grade 1 SPEEs, corneal filaments, and tear film debris. Conclusion: Although the initial presentations were SPEEs, meibomitis, blepharitis, and conjunctival congestion, these inflammatory conditions were reduced over time with proper management. However, there was an increase in the proportion of patients with cataract. It is important to regularly monitor these patients in order to identify and manage the initial as well as the late ocular manifestations of chronic GVHD.

Simultaneous bilateral computer assisted total knee arthroplasty: the effect of intravenous or intraarticular tranexamic acid.

The use of tranexamic acid (TA) in total knee arthroplasty is well documented. However, there is limited evidence to suggest the use of TA in simultaneous bilateral computer assisted total knee arthroplasty (CATKA). We, therefore, studied the effect of TA, in simultaneous bilateral computer assisted total knee arthroplasty, in terms of blood transfusion, routes of administration and complications. We divided 90 patients into three groups. Group I patients received intravenous normal saline alone (IVNS group). Group II received intravenous TA alone (IVTA group). Group III received intraarticular TA alone (IATA group). Our study confirms that there is significant benefit of using TA but no difference between the intravenous or intraarticular routes of administration.

Troponins in Tako-tsubo cardiomyopathy.

Tako-tsubo cardiomyopathy was first described in Japan in 1990. The clinical presentation of Tako-tsubo cardiomyopathy (TCM) is similar to an acute myocardial infarction with patients having chest pain, ST segment elevations on EKG and elevated cardiac biomarkers. In TCM, however, the elevation in cardiac enzymes is usually mild. We report a case of TCM where the patient had Troponin I elevation up to 42.3 ng/ml. To the best of our knowledge, this is the first case in which such high troponins have been reported in a patient with Tako-tsubo cardiomyopathy.
