Can blood flow restriction therapy improve quality of life and function in dissatisfied knee arthroplasty patients?

Aims: Approximately 10% to 20% of knee arthroplasty patients are not satisfied with the result, while a clear indication for revision surgery might not be present. Therapeutic options for these patients, who often lack adequate quadriceps strength, are limited. Therefore, the primary aim of this study was to evaluate the clinical effect of a novel rehabilitation protocol that combines low-load resistance training (LL-RT) with blood flow restriction (BFR).

International consensus-based ranking of definitions for poor response to primary total knee arthroplasty: a Delphi study.

Introduction: This study aimed to rank definitions for measuring poor response one year after TKA, after assessing the face validity and feasibility of existing or newly proposed definitions.

Materials And Methods: An international, three-round, online modified Delphi study was conducted with sixty-nine panelists from twenty-three countries. Definitions were derived from a literature review or were newly proposed by an expert group.

Exploration of adverse consequences of total knee arthroplasty by patients and knee specialists: a qualitative study.

Objectives: A successful outcome according to the knee specialist is not a guarantee for treatment success as perceived by patients. In this study, we aimed to explore outcome expectations and experiences of patients with OA before and after total knee arthroplasty (TKA) surgery and knee specialists that might contribute to the negative appraisal of its effect, and differences in views between patients and knee specialists.

Methods: Semi-structured interviews were held in Belgium and the Netherlands.

Condylar constrained and rotating hinged implants in revision knee arthroplasty show similar survivorship and clinical outcome: a systematic review and meta-analysis.

Purpose: In revision total knee arthroplasty (TKA) ligament instability and bone defects might require more constraint implants such as a condylar constrained knee (CCK) or rotating hinged knee (RHK). When both implants are suitable, the choice remains controversial. The purpose of this systematic review and meta-analysis was to compare the survivorship and clinical outcome between CCK and RHK in revision TKA.

Digital Rehabilitation after Knee Arthroplasty: A Multi-Center Prospective Longitudinal Cohort Study.

Rehabilitation for total knee replacement (TKA) often involves in-person therapy sessions, which can be time consuming and costly. Digital rehabilitation has the potential to address these limitations, but most of these systems offer standardized protocols without considering the patient's pain, participation, and speed of recovery. Furthermore, most digital systems lack human support in case of need.

Efficacy of total knee arthroplasty (TKA) revision surgery depends upon the indication for revision : a systematic review.

The number of revision total knee arthroplasty (TKA) surgeries has increased over the years and it is expected that its number will keep rising. Most frequent reasons for revision are known to be aseptic loosening, infection, instability, periprosthetic frac- ture, arthrofibrosis and component malposition. The influence of the indication for revision on the outcome scores is not fully understood.

Conservative treatment of knee osteoarthritis.

Osteoarthritis of the knee causes chronic knee pain, loss of function and disability in the ageing population. When no treatment is applied, a guaranteed onset of symptoms and/or structural damage can be observed in the diseased knee. This work reviewed the different published guidelines, proposing combinations of weight reduction, physical therapy and rehabilitation, self-management education programs and pharmacological treatment.

An evaluation of the influence of force- and weight bearing (a)symmetry on patient reported outcomes after total knee arthroplasty.

It has been reported that balance impairments and asymmetrical movement patterns occur in patients after total kne arthroplasty (TKA). The purpose of this study was to evaluate if force- and weight-bearing asymmetry correlate with patient-reported outcomes (PROMs). Twenty patients were prospectively analysed up to 6 months after TKA.

Prevention of Infection and Disruption of the Pathogen Transfer Chain in Elective Surgery.

The COVID-19 pandemic has caused us all to stop our normal activities and consider how we can safely return to caring for our patients. There are many common practices (such as an increased use of personal protective equipment) which we are all familiar with that can be easily incorporated into our daily routines. Other actions, such as cleaning more surfaces with solutions such as dilute povidone iodine or changing the air filtration systems used within operating room theaters, may require more extensive efforts on our behalf.

Are TKA Kinematics During Closed Kinetic Chain Exercises Associated with Patient-reported Outcomes? A Preliminary Analysis.

Background: Kinematic patterns after TKA can vary considerably from those of the native knee. It is unknown, however, if there is a relationship between a given kinematic pattern and patient satisfaction after TKA.

Questions/purposes: Is there an association between kinematic patterns as measured by AP translation during open kinetic chain flexion-extension and closed kinetic chain exercises (rising from a chair and squatting) and a custom aggregate of patient-reported outcome measures (PROMs) that targeted symptoms, pain, activities of daily living (ADL), sports, quality of life (QOL), and patient satisfaction after TKA?

Methods: Thirty patients who underwent TKA between 2014 and 2016 were tested at a minimum follow-up of 6 months.

Improved walking distance and range of motion predict patient satisfaction after TKA.

Purposes: The focus in the evaluation of total knee arthroplasty has shifted from objective measures of implant position and knee function, to patient-reported outcome measures (PROMs). The relation between these two measures was investigated and the possibility of prediction of the patient satisfaction level was evaluated by defining thresholds for improvement of (1) range of motion (ROM), (2) 6-min walk test (6MWT), (3) sit-to-stand test (STS) and (4) quadriceps force after TKA?

Methods: Fifty-seven patients were prospectively tested at preoperative and 6 months postoperative intervals. The ROM, 6MWT, STS-test and quadriceps force were evaluated.

A New Prediction Model for Patient Satisfaction After Total Knee Arthroplasty.

Background: Total knee arthroplasty (TKA) is a proven and cost-effective treatment for osteoarthritis. Despite the good to excellent long-term results, some patients remain dissatisfied. Our study aimed at establishing a predictive model to aid patient selection and decision-making in TKA.

3D printed guides for controlled alignment in biomechanics tests.

The bone-machine interface is a vital first step for biomechanical testing. It remains challenging to restore the original alignment of the specimen with respect to the test setup. To overcome this issue, we developed a methodology based on virtual planning and 3D printing.

Can we predict the natural course of femoroacetabular impingement?

We conducted a multivariate regression analysis (including both radiographic and activity related variables) in patients with osteoarthritis of the hip and structural changes related with femoroacetabular impingement. The purpose of this study was to investigate whether the age at which total hip arthroplasty may have to be performed, can be predicted in patients with femoroacetabular impingement (FAI). In 121 patients with FAI-related osteoarthritis, radiographic variables describing FAI-related parameters were obtained and the patients were questioned about their activity during early adulthood by means of the validated Baecke et al questionnaire.
