Proximal tibial replacement in revision knee arthroplasty for non-oncologic indications [PDF]

Arthroplasty Today, 2020
Proximal tibial metaphyseal bone loss compromises the alignment and fixation of components during revision total knee arthroplasty. In massive, segmental defects with loss of collateral ligamentous support and lack of bone to support the use of ...

Distal femoral replacement in complex revision knee arthroplasty

Nigerian Postgraduate Medical Journal, 2020
Revision knee arthroplasty is often complicated by the presence of bone loss, making the use of conventional revision implants impossible, due to inadequate bone stock and ligamentous stability.

Anatomical and Biomechanical Features of the Lateral Compartment of the Knee and Associated Technical Aspects of Unicompartmental Knee Arthroplasty: Lecture [PDF]

Travmatologiâ i Ortopediâ Rossii, 2023
The frequency of lateral unicompartmental knee arthroplasty is estimated at 1% of the total volume of knee arthroplasties, according to contemporary literature. Recent studies analyzing this type of surgical intervention indicate that when performed with

Impact of Nordic Arthroplasty Register Association (NARA) collaboration on demographics, methods and revision rates in knee arthroplasty: a register-based study from NARA 2000–2017

Acta Orthopaedica, 2022
Background and purpose: We have previously observed differences in treatment and outcome of knee arthroplasties in the Nordic countries. To evaluate the impact of Nordic collaboration in the last 15 years we aimed to compare patient demographics ...

Impact of patient and prosthesis characteristics on common reasons for total knee replacement revision: a registry study of 36,626 revision cases from Australia, Sweden, and USA

Acta Orthopaedica, 2022
Background and purpose: Total knee replacement (TKR) studies usually analyze all-cause revision when considering relationships with patient and prosthesis factors. We studied how these factors impact different revision diagnoses.

Variation and trends in reasons for knee replacement revision: a multi-registry study of revision burden

Acta Orthopaedica, 2021
Background and purpose — Studies describing time-related change in reasons for knee replacement revision have been limited to single regions or institutions, commonly analyze only 1st revisions, and may not reflect true caseloads or findings from other ...

The effect of patient and prosthesis factors on revision rates after total knee replacement using a multi-registry meta-analytic approach

Acta Orthopaedica, 2022
Background and purpose: Characteristics of patients receiving total knee arthroplasty (TKA) and prostheses used vary between regions and change with time. How these practice variations influence revision remains unclear.

Treatment of Unicompartmental Cartilage Defects of the Knee with Unicompartmental Knee Arthroplasty, Patellofemoral Partial Knee Arthroplasty or Focal Resurfacing

Life, 2021
Focal chondral defects are common lesions of the articular cartilage. They are predominantly found on the medial femoral condyle and often progress to osteoarthritis of the knee. Various conservative treatment options are available.

Adverse Local Tissue Reaction Secondary to Corrosion at Multiple Junctions in a Modular, Segmental, Distal Femoral Replacement

Arthroplasty Today, 2023
While adverse local tissue reactions are well described in the total hip arthroplasty literature, there have only been case reports and case series in the total knee arthroplasty literature.

Increases in the rates of primary and revision knee replacement are reducing: a 15-year registry study across 3 continents

Acta Orthopaedica, 2020
Background and purpose — Rates of knee replacement (KR) are increasing worldwide. Based on population and practice changes, there are forecasts of a further exponential increase in primary knee replacement through to 2030, and a corresponding increase in
