Tubercular arthritis of the elbow mimicking as a neoplasm: a case report and literature review
Tuberculous arthritis of the elbow joint is rare. A 38-year-old male patient presented with swelling, pain, and deformity of the elbow. The symptoms first appeared one year ago; he was clinic-radiologically evaluated and diagnosed with neoplasm. The patient underwent biopsy to confirm the diagnosis and was found to have tuberculous arthritis and was started on anti-tubercular treatment and underwent surgical debridement. Tuberculous arthritis usually presents with chronic arthritis. However, it can also present in patients with septic arthritis. If untreated, it can cause joint destruction. Hence, early diagnosis and treatment is important
Measuring the outcomes of medial meniscectomies with a femoral end medial collateral ligament release and reattachment in patients with a tight knee: a case series
Partial meniscectomies are the most commonly performed arthroscopic knee procedures, however, are complicated by the presence of a tear in the posterior medial compartment (PMC) in tandem with a “tight knee”. This inhibits adequate spacing for instrumentation access, increasing the chances of causing iatrogenic cartilage damage which can progress to early onset osteoarthritis. We present a unique method for increasing the joint space, in such cases, and avoiding cartilage damage, by performing a femoral end medial collateral ligament release and reattachment (MCLR). Patient outcomes were evaluated in two parts. The first part compared the fourteen patients who underwent a MCLR pre- and post-operatively via the Lysholm and Tegner score, VAS pain scale and knee flexion angle. Finally, the MCLR patients were compared via 1:1 propensity score-matching to patients who underwent a valgus maneuver only for a PMC tear. The patients receiving an MCLR showed a statistically significant improvement (p<0.001) within each of the pre- and post-operative measured variables. When compared with 1:1 propensity score matched and unmatched patients, no statistically significant difference was seen between the Lysholm, Tegner and Flexion angle while VAS pain scale did show a difference. For patients requiring a PMM with a “tight knee”, performing an MCLR provides a clinical and functional improvement in symptoms and showed no statistically significant difference when compared with valgus maneuver only patients. Therefore, it is an effective procedure for increasing the joint space in a patient with a tight knee that requires a partial medial meniscectomy (PMM)
Application of machine learning constructs to predict post-operative complications and adverse events following shoulder hemiarthroplasty
Background: Artificial intelligence (AI) constructs and machine learning (ML) algorithms have demonstrated utility in predicting various clinical, surgical, and financial outcomes. In this study, we applied AI to shoulder hemiarthroplasty (HA) to predict various post-operative complications.
Methods: The sample was queried from the American college of surgeons-national surgical quality improvement program (ACS-NSQIP) database for all shoulder HA cases from 2008-2018. Six ML algorithms-random forest classifier, gradient boosting classifier, decision tree classifier, SVM classifier-tuned model, Gaussian Naïve Bayes classifier, multi-layer perception-analyzed the sample dataset. Postoperative complications included extended length of stay, non-home discharge destination, transfusion, and any adverse event. Each ML model was compared to logistic regression (LR), and model strength was evaluated.
Results: We identified a total of 1585 shoulder HA cases. Mean age, BMI, operative time, and length of stay were 66±12 years, 31±8 kg/m2, 114±61 minutes, and 2.93±6.61 days. Preop hematocrit, longer operative time, and older age were most predictive of extended length of stay. Preop hematocrit, operative time, and ASA class had the highest importance in any adverse events (AAE) prediction. ML models outperformed traditional comorbidity indices, LR, for predicting extended length of stay (79% vs. 66%), non-home discharge destination (79% vs. 65%), any adverse event (78% vs. 66%), and transfusion requirement (82% vs. 63%).
Conclusions: ML algorithms predicted post-surgical outcomes of interest following shoulder HA at a higher rate to conventional LR and can assist orthopedic surgeons in decision making.
A rare case of solitary exostosis of capitate
Exostosis arising from carpal bones is rare and only a few cases have been reported till date. A 29 years old female came to the outpatient department with a localized swelling present on the dorsum of her right wrist since the past three years. On examining the patient clinically, a well-defined protuberance was observed over the dorsal aspect of the right wrist. CT report showed bony outgrowth over the dorsum of the capitate extending beyond the carpometacarpal joint. In surgical intervention, the mass was removed from the base, which grossly had an appearance of chondral origin. The biopsy report confirmed the diagnosis of exostosis (osteochondroma). Hence, excising the exostosis surgically led to achievement of adequate motion of the patient's wrist along with the additional cosmetic correction benefit
Characterization of the knee joint phenotype in the Portuguese population
Background: Neutral constitutional alignment and neutral joint line obliquity has been the standard alignment strategy for total knee arthroplasty. This one-for-all measure may negatively impact gait pattern and knee biomechanics. Novel alignment strategies surged, considering the variability in phenotypes found across the literature, as different populations may present different phenotype distributions. The Portuguese population has a distinct genetic origin, with no phenotype distribution data. Our objective was to characterise the population’s knee morphology, searching and analysing adjacent joint osteoarthrosis, and calculating the pre-disease coronal alignment.
Methods: A retrospective cohort study was conducted. Full-length X-rays performed between 2016-2023 were analysed. Five alignment parameters were measured (LDFA, MPTA, JLCA, TJLA, HKA), and two parameters were calculated (aHKA, JLO). Knees were classified according to the CPAK classification.
Results: For the arthritic cohort, CPAK-I (23%) II (20%) were most common, aHKA increases as KL increases (r=0.8352; p<0.001). For the healthy, Type-II (42%) and Type-I (15%) were most common. For paediatric, Type-II (43%) and Type-V (21%) were most common. CPAK Types-VII/VIII/IX were rare. Differences between genders for healthy and arthritic cohorts were statistically significant. The arthritic had higher prevalence of adjacent joint osteoarthritis.
Conclusions: The Portuguese population presents a similar knee phenotype comparing with other populations, some differences have been found regarding the Asian continent. The most common phenotype was a neutral alignment if either healthy or paediatric, or a varus alignment if knee OA. Coronal alignment may not have a major impact in the prevalence of ankle and hip osteoarthritis; however, higher prevalence is observed in patients with knee OA
Comparison of surgical times of various total knee replacement techniques and assessment of learning curve of robotic total knee replacement: a retrospective study
Background: This study aims to compare the operating times of manual, computer-assisted and robotic- assisted TKA and to calculate the learning curve for image-less robotic-assisted TKA (RATKA).
Methods: This retrospective observational study, conducted at the Centre of Excellence, Bone, Joint and Spine, Meitra Hospital, Kozhikode, Kerala, India, focused on patients aged 60 and above undergoing total knee replacement for stage 4 osteoarthritis. The study included 75 consecutive cases of manual, computer- assisted, and robotic-assisted unilateral total knee arthroplasties performed between May 2021 and September 2022 (18 months). Data was collected from the hospital records.
Results: The surgeon transitioned from learning to proficiency phase of RATKA after 14 cases. In the robotic learning phase, the overall operative time was 113.14 minutes (±8.96), significantly longer than the robotic proficiency phase's average of 98.24 minutes (±2.98) and that of CATKA (99.57±10.700 minutes) and manual TKAs (97.01±7.17 minutes). No statistically significant difference was observed in the global operative time between the proficiency phase RATKAs and the CATKA and manual groups (p=0.139).
Conclusions: By optimizing techniques and modifying workflow, one can swiftly overcome the initial learning curve of RATKA and achieve operating times comparable to manual TKA. To enhance efficiency and productivity, the study proposes a revised workflow modifying various rate limiting surgical steps
The use of arthroscopy in diagnosing and treating sports-related cartilage lesions
Background: Sports-related cartilage lesions pose challenges for athletes. Cartilage, vital for smooth joint movement, can be damaged. Arthroscopy, a minimally invasive procedure, allows precise diagnosis and treatment of joint issues, offering quicker recovery and minimal scarring, enhancing orthopedic interventions. This study aimed to assess the use of arthroscopy in diagnosing and treating sports-related cartilage lesions.
Methods: This prospective observational study was conducted at the department of orthopaedics and traumatology, Life Line Hospital Moulovibazar, Mount Adora Hospital Sylhet, MAG Osmani Medical College Hospital Sylhet, Bangladesh from January 2022 to December 2023. As the study subjects, a total of 58 patients with non-surgically treated acute or chronic sports-related cartilage lesions were enrolled by using a purposive sampling technique. After 6 months, a follow-up report was recorded. Data were analyzed by using Microsoft Office tools.
Results: In this study, 72% of participants underwent cuff repair, with the remaining 28% opting for loop repair. The arthroscopic assessment revealed anterior medial cartilage lesions in 34% and anterior lateral lesions in 28%. Posterior medial, posterior lateral, and mid-talus dome cartilage lesions were observed in 17%, 5%, and 16%, respectively. Capsule repair was employed in 86% of cases. Significant improvement in hip range of motion, as well as radiological parameters like lateral center-edge angle, alpha angle (anteroposterior), and alpha angle (Dunn), was observed 6 months postoperatively (p<0.001).
Conclusions: In detecting and treating sports-related cartilage lesions, arthroscopy is an effective method. This minimally invasive less painful treatment approach contributes to faster rehabilitation and a quicker return to normal activities
A comprehensive comparative study on mid-term clinical and functional outcomes in Indian patients following bilateral total knee arthroplasty: assessing the impact of body mass index on post-total knee arthroplasty results
Background: Limited research exists on Indian obese patients undergoing simultaneous bilateral total knee arthroplasty (bTKA), necessitating a comprehensive and comparative analysis with non-obese counterparts. This study presents an observational and prospective assessment of Indian patients who underwent cruciate retaining/posterior stabilized (CR/PS) metal-backed implant surgeries from 2016 to 2019.
Methods: The study encompassed 190 patients (380 knees) undergoing bTKA, classified by World Health Organization (WHO) weight stratification: normal weight (cohort 1, n=51), overweight (cohort 2, n=85), and obese (cohort 3, n=54). Primary endpoints were implant survivorship and revision rates, with secondary endpoints including range of motion (ROM), knee society score (KSS), Western Ontario and McMaster Universities osteoarthritis index (WOMAC), and SF-36 scores.
Results: Female representation dominated all groups (88.24%, 87.06%, and 90.74%). End-stage osteoarthritis occurred in 94.12%, 96.47%, and 98.15%, respectively. Over the 3-year follow-up, four fatalities occurred, with 186 patients completing the study. ROM showed significant improvement after three years, with baseline values increasing from 93.29°±18.29° (cohort 1) to 123.97°±2.28°, 122.86°±5.03°, and 122.67°±4.77°, respectively (p<0.001). KSS demonstrated substantial improvement (cohort 1: 89.87±6.48, cohort 2: 90.47±8.40, cohort 3: 90.52±8.07) after three years. A 100% success rate and no revisions indicated implant durability. WOMAC and SF-36 questionnaires exhibited significant improvements in pain, stiffness, and overall well-being (p<0.001) after bTKA.
Conclusions: This mid-term CR/PS knee survival analysis underscores 100% implant functionality, improved knee function, and enhanced quality of life for all patients, irrespective of their body mass index (BMI). Simultaneous bilateral TKA with CR/PS implants demonstrates favourable outcomes, affirming its efficacy as a viable treatment option
Floating total knee: periprosthetic fracture of the distal femur combined with tibial plateau fracture in primary total knee arthroplasty
We are currently witnessing an increasing number of complications associated with arthroplasty, both due to its greater prevalence, whether primary or revision, and to the population's longer average life expectancy. Periprosthetic fractures associated with a floating knee, in the context of total knee arthroplasty, are rare and their treatment is challenging. We present a case of ipsilateral periprosthetic fracture of the distal femur combined with fracture of the tibial plate in total knee arthroplasty. The 80-year-old female patient was admitted to the emergency department after falling from her own height at home. She reported diffuse pain in her right knee and associated functional incapacity. The limb was stabilized and immobilized in a posterior long leg splint. Initial X-rays showed an ipsilateral periprosthetic fracture of the distal femur and medial tibial plate. The patient's only previous surgery was a total right knee arthroplasty performed in 2020. She underwent surgical treatment with osteosynthesis of the distal femur with a locked anatomical plate and arthroplasty revision of the tibial component. Periprosthetic fractures associated with knee arthroplasty typically involve the distal femur. Fractures involving the tibia are rare and usually occur in the medial tibial plate, in the presence of detachment of the tibial component. There is little published literature on this type of fracture in elderly patients. Periprosthetic fractures in total knee arthroplasty require individualized and planned treatment according to the personality of each fracture and the existence or not of prosthetic detachment
Advances in stem cell therapy for articular cartilage lesions: clinical evidence and future directions: a systematic review
The significance of articular cartilage, an essential connective tissue, cannot be overstated in relation to joint health and functionality. Nevertheless, the human body might have adverse effects due to traumatic incidents, degenerative conditions, or repetitive stress, resulting in the manifestation of pain, inflammation, and impaired functionality. The primary objective of this study is to assess the effectiveness of stem cell therapy in the treatment of articular cartilage damage such as lesions. The systematic review was conducted adhering to the PRISMA principles. Boolean logic is employed in the search technique to integrate phrases pertaining to stem cell therapy, articular cartilage diseases, and biological processes. The research employs a range of databases and medical subject headings (MeSH) in order to facilitate a thorough examination. The stem cell therapy in the treatment of articular cartilage lesions has great potential. It enhances management and treatment outcomes for individuals afflicted with cartilage abnormalities. It is beneficial particularly those diagnosed with osteoarthritis (OA). Encouraging outcomes, such as alleviation of pain and improvement in functionality have been reported. Additional investigation is required to enhance therapy regimens, encompassing cell dosage, delivery techniques, and supplementary medicines. The use of stem cell therapies necessitates the imperative collaboration among researchers, doctors and regulatory agencies
