Clinical outcomes and survival comparison between NexGen all-poly and its metal-backed equivalent in total knee arthroplasty.

Purpose: This study aims to compare total knee replacement (TKA) with NexGen All-Poly (APT) and NexGen Metal-Backed (MBT) in terms of implant survivorship, reasons leading to implant failure and functional results of defined age categories.

Methods: A single-centre, retrospective evaluation of 812 patients who underwent knee replacement with NexGen CR between 2005 and 2021, comparing a modern congruent APT component to a modular MBT equivalent component using a similar surgical technique at a notable mean follow-up duration. Implant survival, functional outcomes using the Knee Society Score and range of motion were evaluated and compared in different age categories.

Biomechanical analysis of all-polyethylene total knee arthroplasty on periprosthetic tibia using the finite element method.

Background And Objective: Total knee arthroplasty (TKA) with modern all-polyethylene tibial (APT) components has shown high long-term survival rates and comparable results to those with metal-backed tibial components. Nevertheless, APT components are primarily recommended for older and low-demand patients. There are no evidence-based biomechanical guidelines for orthopaedic surgeons to determine the appropriate lower age limit for implantation of APT components.

Advantages in Prognosis of Adult Patients with Ewing Sarcoma: 11-years Experiences and Current Treatment Management.

Ewing sarcoma (ES) is an exceptionally rare tumor in adults. Data regarding outcomes of adult patients with ES and experiences with age-adapted therapeutic strategies are very limited. The aim of this study was to evaluate prognostic factors and clinical outcome in a cohort of adult patients treated according to pediatric protocols in the Czech Republic.

Severe cobalt intoxication following hip replacement revision: clinical features and outcome.

Context: Cobalt intoxication has become more frequent due to the wide use of metal hip implants.

Case Details: A 56-year-old male patient underwent total hip prosthesis, with a ceramics-on-ceramics implant. Almost 3 years later, it was replaced by metal implant containing cobalt, chromium, and titanium.

Use of the harmonic system in total hip arthroplasty: a prospective, comparative, observational study.

We compared technical issues, postoperative outcomes and surgical complications of total hip arthroplasty when using the harmonic scalpel (HS) when compared with conventional techniques (CT) in a prospective, comparative observational study. Thirty patients undergoing total hip arthroplasty were assessed. Operative time, blood loss in drains, postoperative pain, soft tissue injury and complications were recorded.

Total hip replacement with the CLS expansion shell and a structural femoral head autograft for patients with congenital hip disease.

Background: Reconstruction of a dysplastic acetabulum in a patient with osteoarthritis of the hip may be accomplished with a variety of surgical techniques. The aim of our study was to assess the outcomes of total hip replacement with the uncemented CLS expansion shell and a structural femoral head autograft to augment the deficient acetabulum in patients with osteoarthritis secondary to congenital hip disease.

Methods: Between 1990 and 1994, we used a CLS expansion shell with a structural femoral head autograft in forty-three consecutive patients (forty-three hips) with osteoarthritis secondary to congenital hip disease.
