Purpose: This study aims to compare the 2-year clinical outcomes of meniscal reconstructions using allograft versus autograft tissue, with a focus on patient-reported outcomes, complication rates and surgical revision rates.
Methods: This prospective comparative cohort study included 60 patients (ages 18-60 years) undergoing meniscal reconstruction. Patients were divided into an allograft group (n = 31) and an autograft group (n = 29; Hamstring tendon = 25 and patellar tendons = 4).
Purpose: To compare the clinical outcomes between opening wedge high tibial osteotomy (OWHTO) and unicompartmental knee arthroplasty (UKA) in patients with Ahlbäck Grade 3 medial compartmental knee osteoarthritis (OA) using a propensity score matching (PSM) analysis.
Methods: This retrospective study included all OWHTO and UKA procedures performed between 2016 and 2021 at a single institution. Inclusion criteria were patients diagnosed with medial knee OA, specifically Ahlbäck Grade 3 arthritis.
Background: The applicability of the coronal plane alignment of the knee (CPAK) classification for unicompartmental knee arthroplasty (UKA) is not yet clear. The current study aimed to address the following questions: 1) what is the distribution of the CPAK classification among patients who underwent medial UKA? and 2) what would be the clinical outcomes for patients whose coronal alignment and joint line obliquity have either changed or been maintained postoperatively?
Methods: This retrospective study involved 325 patients treated with fixed-bearing medial UKA between 2017 and 2019 following a kinematic alignment strategy and using cemented resurfacing implants. Long-leg standing radiographs were utilized for all preoperative and postoperative measurements.
Purpose: To compare clinical and radiological outcomes of medial opening wedge high tibial osteotomy (MOWHTO) using two different alignment methods: the alignment rod (AR) versus the gap measurement (GM) method. The primary outcome was to report the surgical accuracy of coronal plane corrections in each method.
Methods: Patients who underwent MOWHTO with either AR or GM method between 2014 and 2022 at a single institution, with a minimum of 2 years of follow-up, were included.
Medicago truncatula Nod Factor Perception (MtNFP) plays a role in both the Rhizobium-Legume (RL) symbiosis and plant immunity, and evidence suggests that the immune-related function of MtNFP is relevant for symbiosis. To better understand these roles of MtNFP, we sought to identify new interacting partners. We screened a yeast-2-hybrid cDNA library from Aphanomyces euteiches infected and noninfected M.

In osteoarthritis, the direct anterior approach (DAA) has been promoted for improving early functional results compared with the posterolateral approach (PLA). The aim of this study was to compare these two approaches in FNF using DMC-THA.

Purpose: While the coronal plane alignment of the knee (CPAK) classification serves as a useful guide in personalising total knee arthroplasty (TKA), the extent of its correlation with segmental coronal extra-articular knee deformities remains uncertain. This study aims to investigate the potential correlation between CPAK matrix groups and segmental coronal extra-articular deformities in prearthritic knees, shedding light on the relationship between these two factors that seems to be both essential to perform personalised TKA.
Materials And Methods: A radiological assessment of 1240 nonarthritic knees was performed by evaluating lower limb measurements following the protocol established by Paley et al.
Purpose: This study aims to identify the demographic and morphological features of valgus knee deformity with unilateral osteoarthritic knee in the coronal plane. A secondary aim was to identify the distinct phenotypes of valgus knees in Hirschmann's phenotype and the coronal plane alignment of the knee (CPAK) classifications before and after a knee osteotomy (KO).
Methods: A total of 107 patients (57 female and 50 male) with a mean age of 42.
Purpose: The tipping point (TP) of the knee joint is the centre of rotation of the joint in the coronal plane. This study aimed to define the TP in medial opening wedge high tibial osteotomy (MOWHTO).
Methods: Data from 154 consecutive patients with varus knee malalignment, who underwent MOWHTO between 2017 and 2021, was retrospectively reviewed.
Background: Obesity can be a source of higher failure rates and inferior clinical outcomes after total knee arthroplasty (TKA). The aim of this study was to compare outcomes, failure rates, and stress distributions of TKA in obese patients using a short, long, or no tibial stem.
Methods: A matching process based on the type of stem used and the age allowed included 180 patients who had a body mass index (BMI) > 30 and underwent a TKA between January 2010 and December 2019, with a minimum follow-up of 2 years.
Introduction: Unicompartmental Knee Arthroplasty (UKA) and High Tibial Osteotomy (HTO) are two valid options in the treatment of Anteromedial Osteoarthritis (AMOA) of the knee with UKA being mainly performed in cases of Intraarticular deformity (IA) and HTO in cases of Extraarticular deformity (EA). The exact unintentional effect of UKA on EA deformity and HTO on IA deformity is still not well understood. The aim of this study was to assess this unintentional effect of UKA on EA and HTO on IA deformities respectively.

Thus, some surgeons have used a technique of osteochondral autograft using a rib to fix an articular bone loss to manage both of these tissue losses.
Presentation Of Case: We present the case of a 25-years-old patient, who had a complex open elbow injury.
Angiosperms represent most plants that humans cultivate, grow, and eat. However, angiosperms are only one of five major land plant lineages. As a whole lineage, plants also include algal groups.

Hypothesis: No change in PTS or PH would result after MOWHTO with the freehand technique, regardless of the degree of the coronal plane correction.
Background: Porous tantalum components and augments have demonstrated short to midterm fixation stability in acetabular total hip arthroplasty (THA) revision but do not offer a novel option to decrease the postoperative dislocation rate. Recently, dual mobility (DM) cups have gained interest to decrease the prevalence of recurrent hip instability after revision hip arthroplasty, but this issue was not confirmed combined with use of tantalum reconstruction devices. Therefore, we did a retrospective study aiming to: (1) evaluate at a 5-year minimum follow-up period the dislocation rate (and other intra- and postoperative complications), (2) assess radiographic results specifically looking at osseointegration and restoration of the hip center, (3) and also clinical results in a cohort of patients who underwent complex acetabular reconstruction with trabecular metal revision components associated with a cemented DM socket.

Anterior closing wedge high tibial osteotomy (ACW-HTO) for PTS correction is a validated procedure in revision ACL reconstruction (ACLR).
Purpose/hypothesis: The aim of this study was to evaluate the effect of combined ACW-HTO and at least a second revision ACLR procedure on knee stability, function, and sports performance in a large series of patients.
Mortality related to femoral neck fractures remains a challenging health issue, with a high mortality rate at 1 year of follow-up. Three modifiable factors appear to be under control of the surgeon: the choice of the implant, the use of cement and the timing before surgery. The aim of this research project was to study the impact on mortality each of these risk factors play during the management of femoral neck fractures.

Methods: Between January 2019 and October 2021, 59 DFO were performed in a single center. Following application of the eligibility and exclusion criteria, radiographic measurements and analysis was performed for 24 patients by two independent observers, then repeated after one month.
Background: It is estimated that surgical procedures account for 20%-30% of the greenhouse gases emissions from health-care systems. Total knee replacements (TKR) are one of the most frequently performed procedures in orthopaedics. The aim of this study was to identify and quantify the environmental impacts generated by TKRs, the factors that generate the most emissions, and those that can be easily modified.

Introduction: Associating posteromedial and anterolateral approaches should improve fracture line visualization and optimize bicondylar tibial plateau fracture reduction compared to a single midline approach. The present study aimed to compare postoperative complications rates and functional and radiographic results after double-plate fixation via either a single or a dual approach. The study hypothesis was that double-plate fixation using a dual approach provides equivalent complications rates with improved radiographic results compared to a single approach.
