Mechanical or anatomical alignment techniques create a supposedly 'biomechanically friendly' but often functionally limited prosthetic knee.Alternative techniques for alignment in total knee arthroplasty (TKA) aim at being more anatomical and patient-specific, aiming to improve functional outcomes after TKA.The kinematic alignment (KA) technique for TKA has shown good early clinical outcomes. Its role in extreme anatomical variation remains to be defined.The restricted KA technique for TKA might be a reasonable option for patients with extreme anatomical variation.While unicompartmental knee arthroplasty (UKA) has many advantages over TKA, the revision rate remains higher compared with TKA. One major explanation is the relative ease with which a UKA can be converted to a TKA, compared with revising a TKA. This can be considered as an additional advantage of UKA. Another reason is that surgeons favour revising a UKA to a TKA in cases of degeneration of the other femorotibial compartment rather than performing a relatively simple re-operation of the knee by doing an additional UKA (staged bi-UKA).

5-year migration and inducible displacement of the uncemented LCS and ATTUNE rotating platform knee systems: a secondary report of a randomized controlled RSA trial.

Background And Purpose: Early migration of the uncemented cruciate-sacrificing rotating platform ATTUNE and Low Contact Stress (LCS) tibial components was classified as at-risk for aseptic loosening rates exceeding 6.5% at 15 years based on recent fixation-specific migration thresholds. In this secondary report of a randomized controlled trial (RCT) we aimed to evaluate whether the 5-year migration, inducible displacement, and the clinical outcome of the ATTUNE components were comparable to those of the LCS.

Background And Purpose: Measuring patient satisfaction after total hip (THA) and total knee arthroplasty (TKA) is important. We aimed to cross-culturally adapt and examine the psychometric properties of the self-reported Goodman Satisfaction Score (GSS) in a sample of Norwegian patients following primary THA and TKA.
Methods: The GSS was translated and adapted into Norwegian (GSS-NO) following standard guidelines.

Introduction: Multiple sclerosis (MS) may negatively influence the patient-reported outcomes measures (PROMs) when undergoing total knee arthroplasty (TKA). However, functional outcomes in this select population remains poorly characterized. This study aimed to compare clinical outcomes and rate of achieving Minimal Clinically Important Difference for Improvement (MCID-I) and Minimal Clinically Important Difference for Worsening (MCID-W) between MS and non-MS TKAs.

Introduction: Extraarticular deformity (EAD) with knee arthritis is a complex condition involving tri-planar bone deformity with pathological malalignment and chronic soft tissue contracture or laxity in the knee joint. Intraarticular correction by TKA, which was previously performed with conventional manual jig by mechanical alignment technique, had its limits and difficulties especially extensive soft tissue release and risk of jeopardizing the collateral ligaments. Robotic technology allows for reproducible and precise execution of surgical plan and allows adjustment to various new personalised alignment philosophy including functional alignment (FA).
