<b>Objective:</b> To identify and evaluate the main functional assessment tools applied in the postoperative monitoring of patients undergoing total knee arthroplasty (TKA), and to synthesize the functional outcomes reported through these instruments in the current scientific literature. <b>Method</b><b>ology</b><b>:</b> A structured review was conducted following PRISMA 2020 guidelines. Thirty-one peer-reviewed studies were selected through a targeted manual search based on predefined eligibility criteria. Included studies evaluated functional recovery following TKA using validated outcome measures such as the WOMAC, KSS, KOOS, IKDC, SF-36, and SANE. Data extraction focused on the instruments used, patient population characteristics, and reported outcomes. A descriptive synthesis was compiled in Table 1. Additionally, 15 studies with quantitative data were analyzed using a forest plot to illustrate risk ratios (RR) and 95% confidence intervals (CI) for functional improvement. Risk of bias was assessed qualitatively based on methodological rigor, clarity of reporting, and validation of the outcome tools. <b>Results:</b> All included studies reported improvements in functional status following TKA. Most risk ratios ranged from 0.66 to 0.85, indicating a consistent reduction in the risk of postoperative functional limitation. High-quality studies demonstrated more precise effect estimates and greater internal validity. The SANE scale emerged as a valid and practical tool with high responsiveness, including in its culturally adapted Brazilian version. Despite heterogeneity in study design, the direction of effect remained consistent across all included studies. <b>Conclusion:</b> Validated functional assessment tools are essential for monitoring recovery after total knee arthroplasty. Instruments such as WOMAC and SANE demonstrate strong clinical utility and psychometric validity. Their systematic use enhances outcome comparability, supports individualized rehabilitation planning, and improves decision-making in orthopedic care.

This systematic review aimed to evaluate the biomechanical properties, functional performance, and clinical outcomes of different hip prosthesis materials and designs used in total hip arthroplasty (THA). A comprehensive search strategy identified 34 peer-reviewed studies published between 2015 and 2024. The materials investigated included cobalt-chromium-molybdenum (CoCrMo), titanium alloys, PEEK, ceramics, and advanced surface coatings such as polycrystalline diamond (PCD). In addition, dual mobility systems, lattice structures, and additively manufactured and patient-specific implants were assessed. The studies utilized clinical trials, finite element analysis, and biomechanical testing to compare outcomes such as wear resistance, stress distribution, osseointegration, and range of motion. The findings demonstrated that titanium alloys and porous lattice structures reduce stress shielding, while ceramics and CoCrMo provide superior wear resistance. Dual mobility implants improved joint stability and range of motion, particularly in high-risk patients. PEEK and PCD showed promising properties but lacked robust long-term data. The integration of advanced manufacturing technologies and material innovations has led to more personalized and biomechanically efficient solutions for THA. Further longitudinal studies are needed to validate these developments. This review provides a critical synthesis of the biomechanical, functional, and clinical implications of contemporary hip prosthetic systems.

<b>Objective:</b> This integrative review aims to critically examine the clinical management of periprosthetic joint infections (PJI) in total hip arthroplasty (THA), emphasizing decision-making strategies, diagnostic advancements, and therapeutic innovations. The study focuses on the complexity of infection control, microbial resistance, and individualized treatment planning. <b>Methods:</b><b> </b>A systematic review of the literature was conducted using PubMed, Scopus, Web of Science, and Google Scholar, targeting studies published between 2015 and 2025. Articles were selected based on their contribution to understanding the clinical, microbiological, and surgical aspects of PJI in THA. Fifty-five studies met the inclusion criteria and were analyzed descriptively.<b> </b><b>Results:</b><b> </b>PJI in THA is influenced by multifactorial risk profiles, including obesity, diabetes, and immunosuppression. Staphylococcus aureus, particularly MRSA, remains the most frequently isolated pathogen, followed by Gram-negative organisms and fungal species. Diagnostic innovations such as next-generation sequencing have enhanced pathogen detection, while two-stage revision remains the gold standard for chronic infections. Emerging strategies—such as antimicrobial coatings, tailored antibiotic protocols, and multidisciplinary care models—demonstrate promise in improving clinical outcomes. <b>Conclusion:</b><b> </b>Managing PJI in THA necessitates a comprehensive and individualized approach, integrating early and accurate diagnosis, pathogen-specific treatment, and advanced preventive measures. The integration of emerging technologies and personalized care pathways is critical to optimizing outcomes and reducing the clinical and economic burden of PJI.

Knee osteoarthritis (KOA) is a chronic degenerative joint disorder that significantly impairs mobility and quality of life. While surgical interventions such as total knee arthroplasty (TKA) are effective in severe cases, conservative treatments are critical for early and intermediate disease management. This review evaluates the efficacy, safety, and clinical applications of both conservative and surgical treatment approaches, including lifestyle modifications, physical therapy, pharmacological interventions, regenerative medicine, and surgical procedures. The integration of a multidisciplinary approach is emphasized as a key strategy for optimizing clinical outcomes and tailoring interventions to disease severity.

<b>Background:</b> Multiple epiphyseal dysplasia (MED) a rare form of skeletal dysplasia with early-onset osteoarthritis affecting the hip and knee joints. There is paucity of evidence regarding the long term outcomes of arthroplasty in this patient cohort. This is the first study to describe the outcomes of bilateral arthroplasty of the hip and knee in patients with MED. <b>Methods:</b> A prospective study of patients with MED who underwent bilateral staged total hip arthroplasty (THA) and bilateral simultaneous total knee arthroplasty (TKA) between July 2013 to April 2014. Preoperative and postoperative clinical and radiographic assessment including functional outcomes namely Merle d’aubigne score, Harris hip score (HHS), Knee society score (KSS) and numeric rating scale (NRS) for pain were recorded in prospective database and evaluated. <b>Results:</b> 3 patients (female - 1 / male - 2) with MED who underwent bilateral lower limb arthroplasty of the hip and knee were reviewed periodically with an average followup of 7.31 years. Mean preoperative Merle d'Aubigné score (6.33 ± 0.58), HHS (31.83 ± 5.31) and KSS (28.67 ± 7.97) increased following bilateral lower limb arthroplasty with mean postoperative Merle d'Aubigné score (16.33 ± 0.58), HHS (84.33 ± 5.99) and KSS (86.33 ± 7.09) (<i>P</i><0.001). Mean NRS decreased from 7.33 ± 0.58 in the preoperative period to 0.67 ± 0.58 at the most recent followup (<i>P</i><0.001). One patient had heterotrophic ossification following<b> </b>THA. There were no revisions.<b> </b><b>Conclusions:</b> Bilateral lower limb arthroplasty of the hip and knee is a good treatment option to restore function and mobility in MED patients with advanced degenerative arthritis. Careful preoperative planning, meticulous surgical techniques, patient focussed postoperative rehabilitation with multidisciplinary team approach are vital to ensure good functional outcomes and implant survivorship.

For the adequate treatment of bone fractures, it is necessary to have knowledge about mechanical concepts as the interaction of implants and bone. The understanding of the concept of stress riser must be clear for surgeon for adequate surgical planning, thus preventing refracture due to incorrect application of implants. This article presents the concept of stress riser applied to orthopedics and briefly discussion.

To date, numerous operative techniques for hallux valgus correction have been introduced by several authors. The past decades have seen a surge in minimally invasive techniques partly because of the increasing demand for cosmetic surgery. Undoubtedly, the 2<SUP>nd</SUP> generation minimally invasive procedure introduced by Bösch et al. largely has an advantage of minimizing scars; but the result can vary in the hands of different surgeons. More recently, the 3<SUP>rd</SUP> generation Chevron-Akin procedure has demonstrated good results for mild to moderate deformity correction, however, a special equipment such as Shannon burr is required to perform this procedure. In this study, we report the operative outcome of proximal transverse derotational metatarsal osteotomy followed by cannulated screws or Kirschner’s wires fixation across the osteotomy for three patients with moderate hallux valgus. Satisfactory to excellent correction was achieved by lateral translation and supination of the distal fragment for all three cases.
