RESUMEN
AIM AND OBJECTIVE: Software-guided realignment is proposed as an easy and accurate method of achieving simultaneous multiaxial correction. The accuracy and efficacy in periarticular problems have not been investigated fully. This study investigates the results and possible clinical benefits. MATERIALS AND METHODS: A retrospective review was performed in 24 patients with 27 periarticular deformities of the lower limb treated by the Ilizarov technique. Bony realignment was achieved by a software-guided hexapod realignment device. The deformity category, deformity severity score (DSS) and individual deformity component scores were measured for objective quantification of each deformity. The periarticular level, number of manoeuvres, correction period and any difficulties in the execution of the correction manoeuvre were noted. Pre-procedure and post-procedure values of deformity parameters were analysed to estimate the accuracy and efficacy of the realignment device. RESULTS: The correction manoeuvre was accomplished successfully in all patients except two. The mean correction period was 14.9 days (range, 5-38 days). The mean pre-procedure DSS was 18.7 (range 6.3-27.3), which reduced to a mean post-procedure value of 1.5 (range, 0-7.9) with a 92.0% deformity correction (p-value < 0.001)). There was a significant reversal of individual deformity components. DSS values were achieved to an excellent level (< 3.5) in 25 deformities and to good and poor levels in one deformity, respectively. CONCLUSION: Software-guided realignments are effective for accurate realignment of periarticular deformities using Ilizarov fixators. These devices offer simultaneous multidimensional corrections even in complex multiplanar deformities and simplify the task of deformity correction. CLINICAL SIGNIFICANCE: The present study assesses the accuracy and efficacy of software-guided realignments using novel concepts of deformity category, DSS and individual deformity component scores, which may overcome some of the shortcomings of conventional assessment methods.

RESUMEN
PURPOSE: The proximal tibiofibular joint (PTJF) can be injured with the structures in the lateral aspect of the knee in a multi-ligament knee injury (MLKI) patient. Such injuries are scarce but require attention in the management of the complex MLKIs. The assessment and management of such injuries are not well described in the English literature. This study describes the frequency of PTFJ injuries, clinical assessment and functional outcomes of such injuries in MLKI patients. METHODOLOGY: The data were collected retrospectively from the cohort from 2013 to 2018. The 84 MLKI were included in the study, out of which 9 patients had associated PTFJ injury. All the PTFJ injuries were operated by one single surgeon (D.S) which involves stabilization with K-wires (Kirschner wire) and fixation with 4 mm cancellous cannulated screw along with reconstruction surgery for MLKI in single stage. RESULTS: The frequency of PTFJ injury in our patient cohort is 10.71%. Three patients out of the nine patients received Larson procedure apart from the fixation of PTFJ. At a mean follow-up of 13 months, the Lysholm score was 77.4 (range: 69-86) and mean modified Cincinnati score was 62 (range: 52-72). There was grade I posterior laxity present in one patient with PCL and PLC injury, one patient with ACL, PCL and PLC injury, and one patient with ACL, PCL, MCL and PLC injury at final follow-up. Terminal flexion of 15° or more restriction was noted in six patients. All patients were satisfied with the outcome. CONCLUSION: Evaluation of PTFJ should be an integral part of preoperative as well as an intraoperative examination of MLKI patients. The fixation of this joint is of utmost importance for the reconstructive ligament procedures on the lateral aspect of the knee. The dial test used for the assessment of the integrity of PLC injury should have a prerequisite of proximal tibiofibular joint stability, otherwise, it can lead to erroneous assessment. LEVEL OF EVIDENCE: IV.
RESUMEN
BACKGROUND: An anatomical double bundle ACL reconstruction replicates the anatomy of native ACL as the tunnels are made to simulate the anatomy of ACL with AM and PL bundle foot prints. The goal of anatomic ACL reconstruction is to tailor the procedure to each patient's anatomic, biomechanical and functional demands to provide the best possible outcome. The shift from single bundle to double bundle technique and also from transtibial to transportal method has been to provide near anatomic tunnel positions. PURPOSE: To determine the position of femoral and tibial tunnels prepared by double bundle ACL reconstruction using three dimensional Computed tomography. STUDY DESIGN: A prospective case series involving forty patients with ACL tear who underwent transportal double bundle ACL reconstruction. METHOD: Computed tomography scans were performed on forty knees that had undergone double bundle anterior cruciate ligament reconstruction. Three-dimensional computed tomography reconstruction models of the knee joint were prepared and aligned into an anatomical coordinate axis system for femur and tibia respectively. Tibial tunnel centres were measured in the anterior-to-posterior and medial-to-lateral directions on the top view of tibial plateau and femoral tunnel centres were measured in posterior to anterior and proximal-to-distal directions with anatomic coordinate axis method. These measurements were compared with published reference data. RESULTS: Analysing the Femoral tunnel, the mean posterior-to-anterior distances for anteromedial and posterolateral tunnel centre position were 46.8% ± 7.4% and 34.5% ± 5.0% of the posterior-to-anterior height of the medial wall and the mean proximal-to-distal distances for the anteromedial and posterolateral tunnel centre position were 24.1% ± 7.1% and 61.6% ± 4.8%. On the tibial side, the mean anterior-to-posterior distances for the anteromedial and posterolateral tunnel centre position were 28.8% ± 4.3% and 46.2% ± 3.6% of the anterior-to posterior depth of the tibia measured from the anterior border and the mean medial-to-lateral distances for the anteromedial and posterolateral tunnel centre position were 46.5% ± 2.9% and 50.6% ± 2.8% of the medial-to-lateral width of the tibia measured from the medial border. There is high Inter-observer and Intra-observer reliability (Intra-class correlation coefficient). DISCUSSION AND CONCLUSION: Femoral AM tunnel was positioned significantly anterior and nearly proximal whereas the femoral PL tunnel was positioned significantly anterior and nearly distal with respect to the anatomic site. Location of tibial AM tunnel was nearly posterior and nearly medial whereas the location of tibial PL tunnel was very similar to the anatomic site Evaluation of location of tunnels through the anatomic co-ordinate axes method on 3D CT models is a reliable and reproducible method. This method would help the surgeons to aim for anatomic placement of the tunnels. It also shows that there is scope for improvement of femoral tunnel in double bundle ACL reconstruction through transportal technique.
RESUMEN
BACKGROUND: The current COVID-19 pandemic has implications on the morbidities of orthopedic patients due to lack of routine follow-ups, and inpatient and outpatient-based interventions. Telemedicine has recently emerged as an alternative for healthcare delivery to the patients and providing them with important information about orthopedic self-care and medications that can be followed without a hospital visit. However, due to lack of physical assessment, telemedicine is bound to have some limitations as well. The aim of this study is to analyze the effectiveness of proactive telemedicine in maintaining follow-up of orthopedic patients, and their satisfaction with telemedicine as an alternative mode of treatment delivery. METHODS: This one-month cross-sectional study enrolled the follow-up patients that visited the orthopedic outpatient-department in February 2020. The patients were sequentially called according to the order of their registration, on a daily basis. Consenting patients were provided with telemedicine-based consultations, and those requiring physical evaluation were called for outpatient visits after documenting the valid reasons. The response-rates and the volume of patients requiring physical visits were measured for different diagnosis-based groups. Patients were asked to complete a questionnaire that included overall patient satisfaction with telemedicine, its effectiveness, and ease in following the telemedicine-based treatment. RESULTS: The response rate to telemedicine was 88.67%. Among the patients availing telemedicine, 71.43% were managed without needing physical visits to the outpatient-department. The need for physical examination and failed patient-doctor communication were the most common reasons for advising physical outpatient visits. The overall satisfaction-rate to telemedicine was 92%, and only 7.2% of patients had difficulty in understanding or following telemedicine-based advice. CONCLUSIONS: Telemedicine can effectively reduce the need for physical visits to outpatient-departments for follow up of orthopedic patients. The response-rate and overall patient-satisfaction rates to telemedicine are high. Further efforts in expanding the use of telemedicine and addressing its limitations, especially those related to the failed communications, are needed to develop it as an alternative to physical orthopedic consultations in the current situation.
RESUMEN
Adjustable-loop devices are relatively new but quite popular and have been routinely used for around a decade in arthroscopic anterior cruciate ligament reconstruction for hamstring graft fixation on the femur. They allow surgeons to adapt to different tunnel lengths, eliminate the need for multiple loop sizes, decrease the "bungee cord effect," maximize the amount of graft within the femoral socket available for incorporation, and allow retensioning of the graft. Apart from these advantages, certain complications are associated with the use of adjustable-loop devices. When the cortical button is being pulled up through the femoral tunnel, it may be pulled up with greater force, causing it to come out of the vastus lateralis, the iliotibial band, or even the skin. When the graft is pulled back from the tibial side, the cortical button may flip in the substance of the vastus lateralis or outside the iliotibial band. This soft-tissue interposition can cause ischemic necrosis of the interposed tissue, soft-tissue irritation, migration of the cortical button, or early loosening of the graft, leading to anterior cruciate ligament reconstruction failure. We describe a percutaneous solution to this common intraoperative technical complication. The outer sheath of a 4.5-mm arthroscope, 4.5-mm acromionizer, or notchplasty burr can be safely used to put the cortical button back against the lateral cortex of the femur.
RESUMEN
Seven new 2,3-dimethoxy-3-hydroxy-2-(1-phenyl-3-aryl-4-pyrazolyl)chromanones (5) have been synthesized by the oxidation of 3-hydroxy-2-(1-phenyl-3-aryl-4-pyrazolyl)chromones (4) with iodobenzene diacetate in methanol. The structures of compounds 5 were established by the combined use of (1)H NMR, IR and mass spectra. All the seven compounds (5) were tested in vitro for their antibacterial activity against gram-positive bacteria namely, Staphylococcus aureus, Staphylococcus epidermidis and Bacillus pumilus and two gram-negative bacteria namely, Salmonella typhi and Pseudomonas aeruginosa. Three compounds, 5d, 5f and 5g, have displayed antibacterial activity comparable to the commercial antibiotics, Linezolid, Cefaclor and Cefuroxime axetial.
