Modern implants in total knee arthroplasty are more patellofemoral joint friendly compared to their traditional design: a systematic review and meta-analysis.

BACKGROUND: Implant designs for total knee arthroplasties (TKA) are continuously evolving to improve outcomes and satisfaction rates after TKA. The present systematic review and meta-analysis aimed to explore the evidence in the literature regarding the outcomes of the Attune knee system over the PFC Sigma knee design and investigate the advantage of one over the other. METHODS: A systematic review and meta-analysis of published studies till August 2021 was performed using the defined eligibility criteria. This was a systematic review of the literature published in the Cochrane Central Register of Controlled Trials (CENTRAL) Library, PUBMED, and EMBASE. The analysis included prospective and retrospective comparative trials comparing TKA by PFC sigma or Attune posterior stabilized (PS) or cruciate-retaining (CR), fixed bearing, or rotating platform systems. Patient-reported outcome measures (PROM) and postoperative patellar complications were analysed in the studies utilizing attune knee system (modern implants) to its counterpart PFC sigma (traditional implants) for TKA. Quality assessment was conducted using NIH Quality Assessment Tool for controlled intervention studies (RCTs and case-control studies). RESULTS: This review included 3 RCTs and the rest, 10 of which were non-RCT, including 5852 patients. ATTUNE designs suggested a statistically significant improvement in KSS over PFC Sigma designs. Other PROMs such as OKS and WOMAC scores yielded comparable results between the two groups. ATTUNE knee prosthesis did not result in better knee range of motion, patient satisfaction, or radiological outcomes than the PFC design. Regarding the complications, attune knee prosthesis demonstrated favourable results over PFC Sigma for anterior knee pain and patellofemoral (PF) crepitus. CONCLUSIONS: The present systematic review highlights better KSS and lesser chances of PF complications favouring a modern implant design over its traditional counterpart. Other patient-reported outcome analyses at a short-term follow-up period were comparable among patients undergoing total knee replacements with two different implant designs. Radiological outcomes for component positioning also suggested similar results among the two groups.

No Additional Benefits of Tissue Adhesives for Skin Closure in Total Joint Arthroplasty: A Systematic Review and Meta-Analysis of Randomized Controlled Trials.

BACKGROUND: This systematic review is aimed to compare the performance of tissue adhesives (TA) as an adjunct or closure method with traditional wound closure methods for cutaneous closure in arthroplasty and evaluate whether they have any added benefits in terms of decreasing wound complications and increasing postoperative patient satisfaction. METHODS: Cochrane Library, PubMed, and EMBASE were searched until February 2021. Randomized controlled trials (RCTs) comparing outcomes of TA with emphasis on skin closure time, in-hospital stay, complication rates, cosmetic scoring systems, and patient satisfaction scores (PSS) compared to subcuticular sutures (SCS) and skin staples (ST) in arthroplasty. The quality of RCTs was assessed using the National Institutes of Health quality assessment tool. RESULTS: Ten RCTs were included. The pooled and the subgroup analysis revealed no significant difference in the wound infection rates, discharge rates, dehiscence rates, and PSS between TA (as an adjunct or closure method) and SCS or ST. TA (as an adjunct or closure method) was significantly (P < .00001) associated with a longer time to closure compared to ST and a shorter time compared to SCS as a closure method. Length of stay was comparable in all groups. CONCLUSION: Using TA in combination with subcuticular sutures or ST or as a cutaneous method of closure does not provide additional benefits in terms of decreased hospital stay, decreased infection rates, or wound discharge rates. The PSS and pain scores of the scars also appear to be comparable to standard wound closure methods. No clear conclusion could be drawn regarding cosmetic scoring systems, because of the paucity of data. LEVEL OF EVIDENCE: Level I (Meta-analysis of RCTs).

Plate osteosynthesis in patellar fractures: a systematic review and meta-analysis.

INTRODUCTION: To perform a systematic review and assess the indications, outcomes, complications, and union rates associated with plate osteosynthesis in patellar fractures compared to tension band wiring. METHODS: The systematic search was conducted for articles in PubMed, Embase Biomedical, Cochrane central, and LILACS databases (date of inception to July 30, 2020). Articles were included if they were randomized control trials, cohort studies, case-control studies, and case series (with more than five cases), which focused on the clinical outcomes of patients with plate osteosynthesis as a treatment for fracture of the patella and had a minimum follow-up of 3 months. All studies were assessed according to their level of evidence, the number of patients, age of patients, fracture patterns described, complications of treatment, and results summarized. Meta-analysis could only be done for two parameters (complications and reoperations) due to the paucity of data and heterogeneity of studies' limited statistical analysis. The data are presented as a review table with the key points summarized. RESULTS: Twenty studies (seven prospective and 13 retrospective articles) identified 533 patients with 534 fractures who had undergone plate osteosynthesis for fracture of the patella. The most common fracture treated with plate osteosynthesis was 34C. CONCLUSION: Basket plate was most commonly used for inferior pole fractures, while mesh plates were for intra-articular patella fractures. Overall plating was associated with better clinical outcomes, fewer complication rates, and high union rates compared to tension band wiring for patella fractures.

Online educational resources for orthopaedic residency-a narrative review.

PURPOSE: Residency programs in the medical education field are considered the keystone in the development of aptitude and skills required for practice. With the worldwide current scenario of the COVID-19 pandemic, there has been a shift in the paradigm especially in the teaching of the residents from face-to-face classes to more and more online sessions. The purpose of this study is to present a compendium of knowledge-providing sites, smartphone applications (apps), YouTube channels, and podcasts that can provide better online resource management for students in the field of orthopaedics. METHODS: Search terms were used for making a list of various online resources which can be of help during orthopaedic residency. An initial list of the selected websites, smartphone apps, podcasts, and YouTube channels was made. The corresponding author with years of teaching experience and faculty for post-graduate and fellowship training programs then selected the final list. RESULTS: A list of 16 websites with brief points on their content and online address along with the availability of free or paid content was identified as being appropriate. A total of 39 apps available for android/apple smartphones, nine podcasts, and 11 YouTube channels were also identified as being extremely useful and have been discussed elaborately in this article. CONCLUSION: Online educational tools are of immense importance in imparting adequate knowledge to an orthopaedic resident and act as an adjunct to conventional teaching methods. This article focuses on presenting various online educational resources in a simple yet concise way, which may be beneficial for the current generation of residents especially in this current time of unprecedented COVID-19 pandemic.

The importance of the online storage of patient data in Indian COVID-19 scenario: A narrative review.

Generation Z has seen drastic changes in the medical sector with the health-care industry constantly updating itself with newer tools to provide quality treatment. The COVID-19 pandemic has greatly tested the services in every aspect of life and has led to an unprecedented increase in the online storage of patient data. Electronic health records (EHRs) are real-time records that make health information of any patient available securely to authorized users. EHRs in the Indian scenario are still in their budding stages, described as "islands of excellence in an ocean of inadequacy." The central institutes and corporate hospitals have implemented it, but the state medical colleges and peripheral health centers have miles to go. These patient data records become an essential tool in physician's decision-making, expertise, and management. One can review the data which is just a click away even after the patients have been discharged, especially in the follow-up period. The current scenario is such that health-care workers and nonhealth-care workers alike share the data of the patients in respect to their records, radiographs, and laboratory data using social media such as WhatsApp, Facebook, and Telegram. In the absence of adequate regulations, the reliability of the EHRs is questionable and doubt creates a preference for the traditional medical services among the health-care workers. To conclude, a clear and precise guideline that can enlighten the patient and health-care workers is the need of the hour. The concerns of online storage of data need to be alleviated and privacy regulations need to be addressed.

Can patient anthropometry predict the anterior cruciate ligament footprint dimensions? - An MRI-based observational study on north Indian population.

Background: Anterior Cruciate Ligament (ACL) reconstruction is one of the most common surgeries being currently done. As we usher into the era of Individualized Anatomic Reconstruction, it is very important to understand the native anatomy of ACL. We aimed to assess the ACL footprint dimensions in our patients and correlate it with anthropometric variables, which can help in preoperative decision making. Method: A total of 143 eligible patients with suspected ACL injury presented during the study period. Out of which 92 were included in the study. Data on patient's age, sex, height, weight and body mass index (BMI) was recorded. The length and area of both the tibial and femoral footprints were measured on MRI. The footprint dimensions were correlated with the recorded anthropometric data. Results: The ACL tibial footprint length and area, and femoral footprint length and area were found to be 13.3 ± 2.23 mm, 142.6 ± 26.16 mm2, 11.2 ± 1.97 mm, 125.8 ± 28.75 mm2 respectively. Footprint in males was significantly larger than females. A weak (ρ- 0.21 to 0.4) correlation with weight and moderate (ρ- 0.41 to 0.6) correlation with height was observed. Multivariate linear regression analysis yielded height to be the only significant predictor of footprint dimension from which predictive equations were drawn. Conclusions: Height was found to be the most significant predictor of footprint dimensions in our patients. The predictive equations and graphs can aid in preoperative surgical decision making resulting in a more anatomical ACL reconstruction and improve the post-operative results.

Reliability and Usefulness of YouTube as a Source of Informative Media for Arthroscopic Tennis Elbow Surgery: A Systematic Review of the Published Videos.

Aims and Objectives: Over the last decade, YouTube has been extensively used as a learning tool for both physicians and patients, but the reliability of this information remains questionable. The purpose of this study was to look for the reliability and quality of videos on tennis elbow arthroscopy on YouTube. Materials and Methods: We used three search terms on YouTube "tennis elbow arthroscopic surgery," "Arthroscopic ECRB release," and "Arthroscopic debridement for tennis elbow," and screened the first 50 videos according to popularity. The videos were included from 2009 to date. Only videos in the English language were included. Repeated videos and videos without sound were excluded. A total of 74 videos were selected for this study and reliability was checked with DISCERN and journal of the American medical association (JAMA) scores. The quality was assessed with the Global Quality Score Criteria (GQSC) score and TEARS (a novel score). Popularity was tested with the video power index (VPI). A pilot study was conducted using 20 videos to validate the TEARS score. Results: In the pilot study, TEARS showed results in accordance with other scores used. The average number of views was 41,644.97, and the average duration was 5.03 ± 3.39 years. The mean value of DISCERN and JAMA was found to be 21.47 ± 6.28 and 1.05 ± 0.92, respectively. GQSC, TEARS, and VPI were found to be 1.70 ± 0.82, 4.17 ± 2.62, and 769,936.9 ± 6,538,851.37. Conclusion: Most of the videos were educational and physicians were targeted. The USA was the major contributor to such videos. The reliability and quality of these videos were found to be of poor quality. The video popularity was however found to be relatively high. The inter-observer reliability was good. Based on the findings, we conclude that the videos are not reliable and could not be used for learning.

Total Hip Arthroplasty in Protrusio Acetabuli: A Systematic Review.

Protrusio acetabuli, or abnormal protrusion of the femoral head into the acetabulum, requires performance of a total hip arthroplasty (THA) for which various reconstruction techniques and outcomes have been described. The aim of this systematic review is to provide a comprehensive analysis of the current evidence, evaluate treatment efficacy, compare surgical techniques, and identify topics for future research along with improving evidence-based decision-making, improving patient outcomes in the management of this condition. A thorough systematic review of the PubMed, Embase, Cochrane Library databases, and Scopus library was conducted, and articles describing techniques of THA for treatment of protrusion acetabuli were extracted. The initial search generated 751 results. After exclusion, 18 articles were included. Of these, eight were prospective studies and 10 were retrospective. Surgery was performed on 783 hips with a mean age of 60 years; 80% of females who mostly had inflammatory arthritis were followed up for 8.86 years (range, 2-15.4 years). Good outcomes have been achieved with THA using uncemented cups with bone graft; however, no conclusion could be drawn with regard to the femoral side. It can be concluded that the concept of restoration of the anatomical hip center of rotation is paramount for good outcome and better survival of the implant is important when using uncemented cups with a bone graft. In addition, screw augmentation for fixation is not recommended unless absolutely necessary. The most common complications were aseptic loosening and heterotopic ossification. While the former required revision, conservative management was administered for the latter.

"Pediatric Patella fractures - A Systematic review".

Background: Patella fractures in the pediatric age group often have a dilemma in their ease of diagnosis and treatment required. Indications for conservative management or surgical intervention in the pediatric population during growth phase are not clearly defined. The current systematic review aims to provide a consensus on the morphological types, treatment options, indications, the outcomes expected and complications and their management. Methods: The review was conducted as per the PRISMA guidelines. Inclusion criteria were (a).Articles published in English, (b) Age <18 years, (c) Patellar fractures including osteochondral fractures. Exclusion criteria includes articles with incomplete data, case reports, biomechanical studies, case series with sample size <2, biomechanical studies, reviews, letter to the editor, or editorials and Non-English language. Results: The review search yielded a total of 18 articles. A total of 288 patients with patellar fractures were included in the review. The average age ranged from 9.6 years to 16 years. The follow-up period ranged from 3 months to 20 years. In total, 49 individuals underwent immobilization with cast or brace application, 4 with spica cast application and 48 with cylindrical cast in extension. Overall, 83 patients in 13 studies underwent surgical fixation most of which underwent wiring. Conclusion: Pediatric patella fracture/dislocations or Osteochondral fractures (OCF) although being a rare event, may be associated with a child with knee injury and swelling. Conservative management in terms of casting and immobilization may be an alternative but surgical intervention should be the primary mode of treatment in such cases.

Increased medial talar tilt may incite ankle pain and predispose ankle osteoarthritis after correction of severity of knee varus deformity among patients undergoing bilateral total knee arthroplasty: a prospective observation.

PURPOSE: Patients with varus knee osteoarthritis usually compensate at the ankle and typically walk with hindfoot valgus alignment. As the neutral weight-bearing axis of the lower limbs is restored with Total Knee Arthroplasty (TKA), ankle and hindfoot biomechanics also acutely change. This study aims to investigate whether any ankle clinical-radiographical changes occur as a result of bilateral mechanical TKA in patients with bilateral Osteoarthritis knee at a minimum follow-up of 6 months. METHODS: The prospective observational study included 61 patients (122 knees) undergoing simultaneous bilateral TKA (mechanical alignment). Tibio-talar angle(TTA), tibial Anterior Surface angle (TAS), lateral distal tibial angle (LDTA), talar-tilt angle (TT), anatomical talocrural angle (aTC), ground surface and distal tibial plafond angle (GP), ground surface and an upper surface of talus angle (GT)and tibial plateau and tibial plafond angle (PP) were measured on long-film radiographs to look for changes in the ankle, whereas functional assessment was done using American Foot and Ankle Society (AOFAS), Foot and Ankle Disability Index (FADI), and Forgotten Joint (FJS-12) scores. Patients were sub-grouped based on the Hip-Knee-Ankle (HKA) axis, and the effect of the severity of knee varus on the ankles after TKA was also analyzed. The minimum follow-up was 6 months. RESULTS: A significant decrease in the tibial plateau-tibial plafond (PP), ground-tibial plafond (GP), and ground-talar dome (GT) angles was noted after TKA (p-value < 0.05). Postoperative functional parameters were comparable to the preoperative status except for FADI, which significantly improved (p-value-0.03). Sub-group analysis based on the severity of knee varus (HKA) revealed GT to be most significantly reduced (p-value-0.036), while the talar tilt (TT) increased (p-value-0.044). Functional outcomes of the ankles clinically improved with the correction of severe knee varus after TKA. At a mean follow-up of 13.2 months post-TKA, 7 out of 61 (11.4%) patients complained of post-TKA ipsilateral ankle pain. CONCLUSION: Mechanically aligned bilateral TKA in severe varus deformity of the knee significantly decreases the GT angle but increases the varus tilt of the talus with lateral talar incongruency and under-coverage. Although the acute correction of severe knee varus deformity aligns the tibia more neutrally, resulting in an overall clinically evident improvement in ankle functional outcome, the increased varus talar tilt remains a deep concern. LEVEL OF EVIDENCE: Prospective, observational, comparative study Level II.

Average Indian Glenoid Sizes Are Smaller than All Commercially Available Glenoid Components: A Systematic Review.

Background: Despite the variability in glenoid sizes geographically, most of the currently available commercial glenoid component designs are based on the glenoid parameters of the Caucasian population which may not be suitable for the Indian population due to a mismatch between the prosthesis and native anatomy. The aim of the present study is to systematically review the literature to determine the average glenoid anthropometric parameters in the Indian population. Methods: A comprehensive literature search was conducted using preferred reporting items for systematic reviews and meta-analyses guidelines in the PubMed, EMBASE, Google Scholar, and Cochrane Library databases from the date of inception to May 2021. Any observational study conducted on the Indian population measuring the glenoid diameters, glenoid index, version, inclination, or any other glenoid measurements were included in the review. Results: A total of 38 studies were included in this review. The glenoid parameters were assessed on intact cadaveric scapulae in 33 studies, on 3DCT in three studies, and 2DCT in one study. The pooled average of glenoid dimensions are as the following- the superoinferior diameter or height was 34.65 mm, anteroposterior1 diameter or maximum width was 23.72 mm, anteroposterior2 diameter or maximum width of the upper part of the glenoid was 17.05 mm, the glenoid index was 67.88, and the glenoid version was 1.75-degree retroversion. Males were having a mean height of 3.65 mm and maximum width of 2.74 mm larger than the females. A subgroup analysis revealed no significant difference between different parts of India in glenoid parameters. Conclusion: The glenoid dimensions in the Indian population are smaller compared to the average European and American populations. The average glenoid maximum width of the Indian population is 1.3 mm smaller than the minimum glenoid baseplate size available in reverse shoulder arthroplasty. Glenoid components specific to the Indian market need to be designed to reduce glenoid failure attributable to the above findings. Level of evidence: III.

Comparison of Surgical Decompression and Steroid Therapy for the Management of Traumatic Optic Neuropathy: A Systematic Review and Meta-Analysis.

Study Design: A systematic review and meta-analysis. Objective: Treatment of traumatic optic neuropathy (TON) has been a subject of debate for many decades due to the scarcity of evidence-based treatment protocols. This review compares surgical decompression (SD) and steroid therapy (ST) as treatment approaches in TON patients. Methods: A PRISMA-guided systematic review using PubMed, Embase, Ovid and Scopus databases was performed till the last search date of July 31st 2021. The outcome of interest was an improvement in visual acuity. A meta-analysis of the odds ratio was performed using a random-effect model and sub-group analysis based upon criteria for assessment of improvement in visual acuity. Results: Sixteen studies (including 1046 patients) were included in the review. The review could identify 590 patients treated with SD and 456 treated with ST. In addition, there was a second cohort of patients presenting with NLP (no light perception). A meta-analysis with a sub-group analysis revealed that there was statistically no significant difference between the two treatment approaches in terms of improvement in VA. Conclusions: There is no difference in treatment results of SD or ST for TON. Several treatment protocols and different criteria for assessing visual acuity led to difficulty in generating evidence for selecting the correct treatment approach.

Total Hip Replacement in Active and Inactive Tuberculosis Hip: A Systematic Review.

Introduction: Tuberculosis of the hip joint is a debilitating disease that can result in severe joint destruction, eventually leading to painful arthritis of the hip. Total hip arthroplasty (THA) in patients with advanced arthritis offers a painless and mobile joint with good functional outcome but some aspects of THA in TB hip have been controversial in the past due to the concerns of disease reactivation, especially when disease activity is factored in. Various factors like timing of surgery, Antitubercular therapy (ATT) initiation timing, reactivation, complications etc needs to be evaluated very carefully before planning for such cases. Methods: Electronic databases like MEDLINE, EMBASE, Cochrane library, Clinicaltrials gov and OpenGrey were searched. The key words used were "Tuberculosis", "Tuberculosis of hip", Hip tuberculosis, "TB", "THR", "total hip replacement", "total hip arthroplasty","THA", "ankylosed hip", "fused hip", "arthrodesis" along with boolean operators "AND" and "OR". Out of a total of 1634 articles, 38 were selected for full text review and 22 articles were finally included in the study. Results: For the timing of surgery most authors relied on the inflammatory markers to settle down with ATT before performing THA. 15 authors advocated use of pre-operative ATT with 6 studies recommending at least 2 weeks and 3 studies advocating atleast 3 months of ATT pre surgery.Single stage THA was performed in most studies(214 hips vs 18 hips) as opposed to 2 or 3 stage surgery. In the active disease 72.8% of the hips had uncemented prosthesis, 25.6% hips underwent cemented and 1.5% hips had hybrid THA fixation. Overall reactivation of the infection was seen in 2.47% cases. All authors reported excellent clinical improvement (mean HHS improvement 37.17 to 88.62).

Medial Patellofemoral Ligament Tear Associated with an Intra-articular Axial Spilt Osteochondral Fracture of the Lateral Femoral Condyle: a "Knee Trap-door" Fracture.

Introduction: Medial patellofemoral ligament (MPFL) prevents lateral dislocation of the patella and acts as a major stabilizer. The tear could be associated with osteochondral avulsion fractures; however, intra-articular split fractures are not seen. Here, we present one unusual case of such a presentation. Case Report: A 16-year-old male presented with a history of recurrent patellar dislocation and inability to bear weight following the last episode. The patient was diagnosed with an MPFL tear with an unusual intra-articular femoral condyle split fracture. The case had significant improvement in functional scores post-surgery. Conclusion: In physically active populations, twisting of the knee could result in an MPFL tear, leading to recurrent patellar dislocation. The treatment remains ligament reconstruction, open, or arthroscopic. Associated intra-articular fractures are very rare with such injuries and need to be addressed due to the high rate of non-union.

Augmentation with Fibertape Leads to Biomechanically Superior but Similar Clinical Outcomes in ACL Surgeries: Systematic Review and Meta-analysis.

Purpose: The current generation has witnessed significant progress in the field of knee arthroscopy. Suture tapes have gained immense popularity due to perceived improved biomechanical support to the graft while it heals. The purpose of the present systematic review is to analyze the biomechanical construct of suture tapes in ACL repairs and reconstructions along with clinical outcomes. Methods: Cochrane Library, PubMed, and Embase were searched until December 2021. All Biomechanical Studies on animal or cadaver knees that compared construct characteristics of suture tape in ACL repair or reconstruction and clinical studies in English focusing on outcomes following suture tape augmentation in ACL repair or reconstruction were included. The quality of clinical studies using the Modified Coleman Methodology Score (MCMS). Results: A total of 16 studies biomechanical and 23 clinical studies were included in qualitative synthesis, leaving nine biomechanical studies for final quantitative analyses. Suture tape revealed biomechanical superiority in terms of ultimate strength, stiffness, cyclic displacement, and elongation of graft, while comparing ACLR with internal brace to standard ACLR. No significant difference in retear rates was seen in clinical studies. Clinical score(IKDC score) was found similar in both augmented and non-augmented construct. Similar results were obtained in biomechanical studies. Conclusion: The use of suture tape as a ligament augmentation in both ACL reconstruction and ACL repair offers more strength, less elongation or displacement, and is biomechanically stable and sound. There is a lack of data to comprehensively comment upon the clinical superiority of the use of internal augmentation. However, a meta-analysis of the retear rates and clinical outcome score revealed similar outcomes between suture tape augmented and nonaugmented groups.

Outcome analysis of ilizarov and monorail fixators in the treatment of nonunion of long bones: A systematic review and proportion meta-analysis.

Introduction: Nonunion of long bones is a major complication following fractures that requires a substantial amount of investment both monetary and time from patients and surgeons. The need to comprehensively understand the complications, outcomes and distraction capability is profound, which necessitates a review of current evidence on special fixators used for distraction. The current systematic review aims to study the available literature on distraction osteogenesis using special fixators (Ilizarov and Limb Reconstruction System) in the management of nonunion (infected and non-infected). Methods: Cochrane Library, PubMed, Scopus were searched until January 2022. The review included all original studies which used Ilizarov or Monorail Fixators/LRS in the treatment of nonunion of long bones. The quality of studies was assessed using the Modified Coleman Methodology Score. Results: A total of 35 original studies with Ilizarov (n = 29) and LRS (n = 8) were selected including two comparative studies. The pooled data meta-analysis and the subgroup analysis of these studies found both Ilizarov and LRS fixator yield similar functional outcomes for the treatment of long bones nonunion. Conclusion: The review was conducted to understand the scenario of nonunion in long bones. Pin tract infection is found to be the most common complication followed by adjacent joint stiffness and deformity. In our review we observed that both external fixator time and index were lower in LRS compared to Ilizarov group. Further RCT are required comparing Ilizarov and LRS fixators to effectively comment upon the superiority of the implants.

Return to sports after ankle reconstruction with tendon grafts in chronic lateral ankle instability: A systematic review and meta-analysis.

Purpose: Anatomic reconstruction using grafts is being performed more frequently in athletes experiencing recurrent chronic lateral ankle instability (CLAI). The purpose of the study was to systematically review the current literature to determine the rates of return to sports (RTS) along with timing in patients with CLAI undergoing ligament reconstruction. Methods: The databases PubMed, Scopus, Cochrane, and Embase were searched based on the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines. Articles quoting on the return to sports rate after lateral ankle reconstruction were included. The rates of return to any sports, return to pre-injury sports, and return to competitive sports along with the timing of return were evaluated and a proportion meta-analysis was performed. Results: A total of 720 patients in 20 studies met our inclusion criteria. The RTS rates for any sports were 95.3%, and 84.3% for pre-injury sports The average time taken for return to sports was 17 weeks. Postoperative functional outcomes, ankle stability, and ROM were significantly improved in comparison to preoperative status. Conclusion: The RTS rates following lateral ankle reconstruction in CLAI showed a high return to any sports, but moderate to high rates for the pre-injury or competitive level of sports. Level of evidence: Level of evidence II.

Conventional rehabilitation post-TKA achieves better knee flexion with higher resource utilization compared to application-based rehabilitation - a systematic review and meta-analysis.

Background: Post-operative physiotherapy is a major component of the effectiveness of knee replacement. Adequate rehabilitation protocols are required for better functional outcomes. With the advent of smartphones and smartwatches, the use of telerehabilitation has increased recently. This study aims to compare tele rehabilitation using various mobile-based applications to conventional rehabilitation protocols. Methods: From Jan 2000 to Jun 2022, all the RCTs from SCOPUS, EMBASE and PUBMED comparing patient-related outcome measures between the smartphone-based app and conventional rehabilitation protocols were scanned and seven studies meeting the eligibility criteria were included in this systematic review and meta-analysis. The quantitative analysis compared outcomes using the knee injury and osteoarthritis outcome score (KOOS), the knee society function score (KSFS), the active range of motion (AROM), Euro-Qol-5D-5L, and MUA. The qualitative analysis compared VAS, NRS, and Time up and go (TUG). Results: The study shows statistically significant improvement in traditional rehabilitation over app based on KSFS score (M.D.: 6.05, p = 0.05) and AROM on long-term follow-up (12 months) (M.D.: 2.46, p = 0.02). AROM was insignificant on 3 months or less follow-up. NRS and VAS were found to be statistically better in app-based groups. No statistically significant results were seen on KOOS, Euro-Qol-5D-5L, MUA and TUG. 90 days of readmission and a number of physiotherapy visits were more in conventional groups. No difference was seen in single-leg stance and satisfaction rates. Conclusions: The present review highlights improved early pain scores and comparable patient-reported outcome analysis at a short-term follow-up period among patients receiving mobile app-based rehabilitation. However, knee range of motion and KSFS score achieved after surgery is analysed to be better with traditional rehabilitation at the one-year end follow-up period.

Kneeling Stress Radiography: A Forgotten Yet Dependable Tool for Postero-lateral Knee Instability.

Introduction: Diagnosing postero-lateral knee instability is a challenge from both clinical and radiologic perspective and can lead to significant morbidity if left untreated. Delayed diagnosis leads to a more demanding surgery and prolonged rehabilitation for the patient. Kneeling stress radiograph is a lost art but remains invaluable in the assessment of postero-lateral knee instability. Methods: This prospective observational study is aimed at re-exploring the undeniable utility of this forgotten tool in early diagnosis of posterolateral knee instability and identifying the mean posterior tibial translation distance (PTTD) and also assessing side to side difference (SSD) between the injured and the contralateral normal knee. Results: Total 27 patients were included in the study, with males being 4.4 times more commonly injured as compared to females. The most common mode of injury was motor vehicle accident (MVA). Out of 27 patients, 11 had isolated PCL (posterior cruciate ligament) injury while the rest had PLC (posterolateral corner) involvement. The mean SSD of PTTD was 8.79 mm in patient with isolated PCL. This was increased by 1.65 times (14.52 mm) in patients with co-existing PLC involvement. Conclusion: Stress radiography is an indelible tool and serves as an adjunct to MRI imaging. It is not a substitute for clinical assessment but assists in early diagnosis and management, facilitating surgical planning and furnishing objective evidence of PCL/PLC functionality which is not possible with any other imaging modality.

Comparison of functional outcomes and complications of cemented vs uncemented total hip arthroplasty in the elderly neck of femur fracture patients: A systematic review and meta-analysis.

Purpose: The neck of femur fractures in the elderly is a global concern. These fractures impair the quality of living and add to morbidity and mortality. A Multitude of treatment options for the same. This systematic review focuses on evaluating outcomes between cemented and uncemented total hip replacement in the elderly population with neck of femur fractures. Material and methods: The search was conducted in databases PubMed, Embase, Scopus, open grey, and Cochrane following PRISMA guidelines. The studies fulfilling the inclusion criteria were included, scrutinized for data analysis, and also quality appraisal of all the included studies was conducted to be included in this article. Results: A total of 7 studies were included (2 RCT, 5 retrospective studies) comprising 1171 THRs. Data analysis showed a higher HHS in cemented compared to uncemented(p < 0.001). The uncemented group had a significantly higher rate of revision, dislocation, and periprosthetic fracture compared to cemented group(p < 0.001). However, VAS score, loosening rates, and heterotopic ossification were similar in both statistically insignificant groups. Conclusion: Choosing between cemented and uncemented techniques had been a controversy with lesser data due to higher morbidity and mortality. This systematic review provides information regarding functional outcomes and complications in both groups. The cemented group had better outcomes and lesser complications which should be preferred in elderly patients as the conclusion of this study. However, a larger RCT with better follow-up is still required. Level of evidence: Level I, systematic review and meta-analysis.
