Finite element analysis of the tibial component alignment in a transverse plane in total knee arthroplasty.

The research aims to analyze the tibial component rotation using the finite element method by resecting the tibia in a transverse plane at an angle between 1.5° (external rotation) and -1.5° (internal rotation).

Posteromedial Release versus Ponseti Treatment of Congenital Idiopathic Clubfoot: A Long-Term Retrospective Follow-Up Study into Adolescence.

Purpose: Although many short-term studies have shown the superiority of Ponseti treatment to surgical treatment, studies with long-term follow-up of patients into adolescence are lacking. The aim of this study was to compare the morphological, functional and radiological results of the two methods into and during adolescent age, when both soft tissue and bony procedures can be performed to correct residual deformities.

Patients And Methods: We retrospectively evaluated two groups of patients diagnosed with congenital idiopathic clubfoot and treated with either the Ponseti method (34 clubfeet) and surgery in the form of posteromedial release (31 clubfeet).

Methods of intra- and post-operative determination of the position of the tibial component during total knee replacement.

Aim Of The Study: To identify the most reliable anatomical landmarks and imaging techniques for assessing the rotation of the tibial component in total knee arthroplasty (TKA).

Methods: An extensive literature review (from January 2016 to March 2019) was performed. We included studies about primary TKA with details concerning the anatomical landmarks used for implanting the tibial component and also imaging studies assessing tibial component rotation.

Relevance of Finite Element in Total Knee Arthroplasty - Literature Review.

Total knee arthroplasty (TKA) is a key surgical procedure for the treatment of severe knee osteoarthritis. Although TKA has very good clinical results, revision knee arthroplasty can sometimes be necessary due to prosthetic components malalignment which leads to early polyethylene wear, instability and aseptic loosening. Currently, the revision risk of TKA at ten years is 5%.

Radiographic Evaluation of Alignment Following Total Knee Arthroplasty - a Systematic Review. Part II.

The aim of this second part is to review the existing described methods for measuring postoperative total knee arthroplasty (TKA) alignment in sagital and axial plane as well as the existing literature regarding the axial plane evaluation with the use of computer tomography. Given that the most frequent mistakes when positioning the total knee arthroplasty components are made in the axial plane, it is necessary to know what are the limits of radiographic evaluation, for which CT scan is the most valuable tool in assessing the rotation of the components.

Radiographic Evaluation of Alignment Following TKA, a Systematic Review.

Postoperative assessment is of paramount importance in primary total knee arthroplasty. A thorough postoperative analysis helps the surgeon anticipate any postoperative potential issues and correlate the preoperative planning with the postoperative result, and provides better understanding of the importance of surgical principles of primary total knee arthroplasty. In addition, postoperative analysis helps the surgeon understand surgical errors and improve future outcomes.

The effect of high tibial osteotomy on the posterior tibial slope.

Introduction: High tibial osteotomy remains a useful procedure for delaying total knee arthroplasty for young patients with unicompartimental medial osteoarthritis of the knee. The tibial posterior slope is essential for both ligament function and knee kinematics. Even though many articles were published in the literature, the long term influence of open wedge high tibial osteotomy on the posterior slope of the tibial plateau remains unknown.

Outcome of iatrogenic collateral ligaments injuries during total knee arthroplasty.

Soft tissue balance is an essential step in total knee arthroplasty by providing a good knee stability and an even distribution of load over the prosthesis components. During surgery, because of the need of having a good balance in most cases is necessary to do some soft tissue release in the medial compartment. Lateral release is far more rare and is generally needed for patients with valgus knees after high tibial osteotomy.
