Comparative Analysis of Surgical Techniques for Anterior Cruciate Ligament Reconstruction: A Prospective Analysis

Introduction: Anterior cruciate ligament (ACL) injuries are common in active individuals and athletes, necessitating effective surgical interventions for optimal recovery. There are various techniques available for ACL reconstruction. This prospective study aimed to compare the outcomes of different surgical techniques used in ACL reconstruction. Materials and methods: Patients with diagnosed ACL injuries were randomly assigned to one of three surgical groups: autograft hamstring tendon reconstruction, autograft patellar tendon reconstruction, and allograft reconstruction. Preoperative assessments included clinical evaluations, imaging studies, and functional scoring. Postoperative follow-up assessments were conducted at regular intervals, examining clinical outcomes, graft integrity, and patient-reported functional scores. Statistical analysis employed appropriate tests to compare the groups. Results: Preliminary findings indicate that all three surgical techniques resulted in improved stability and function postoperatively. However, detailed analysis revealed nuances in outcomes, such as differences in recovery time, graft integration, and complication rates among the three groups. Notably, the autograft hamstring tendon reconstruction group demonstrated superior functional scores in the early postoperative period. Conclusion: This study contributes valuable insights into the comparative effectiveness of different surgical techniques for ACL reconstruction. While all approaches improved stability and function, nuances in outcomes emphasize the importance of tailoring surgical decisions to individual patient characteristics. Further long-term follow-up and subgroup analyses are warranted to refine recommendations for optimizing ACL reconstruction strategies

Influence of Cobalt (II) Chloride Catalysed on the Thermal and Optical Characterization of PEO Based Solid Polymer Electrolytes

Solution-casting technique was employed for the preparation of solid polymer electrolyte based polyethylene oxide (PEO) with 0, 1, 3 and 5 weight percentage cobalt chloride (CoCl2) films were characterized by X-ray Diffractometry (XRD), Differrential Scanning Calorimetry (DSC), Scanning Electron Microscope (SEM) and Ultra Violet-Visible (UV-Vis.) Spectroscopy methods. The optical band gaps, absorption band edges and Urbach energy shows decrease with increasing of Co+2 ion concentration in the polymer matrix because of the formation of free radicals or cluster. The Thermogravimetry (TG) and Derivative Thermogravimetry (DTG) were used to examine the thermal stability of the film and it was found that the stability of the complexes is higher than that of the pure PEO due to the addition of CoCl2. The wavelength position of a fluorescence emission band varied by increasing of a dopant wt % of salt
