Total Knee Arthroplasty and Clinical Findings

July 23, 2020 updated by: Murat EMİRZEOĞLU, Karadeniz Technical University

Investigation of the Effect of Total Knee Arthroplasty on Proinflammatory Cytokine Level, Pain Severity, Functional Status, Joint Position Sense and Radiographic Findings

Knee osteoarthritis is a common disease that causes pain and loss of function. Total Knee Arthroplasty (TKA) is a frequently used surgical method in the treatment of severe knee osteoarthritis. The aim of this study was to investigate the effect of TKA on IL-6, TNF-α and IL-1β cytokine levels, pain intensity at rest and walking, knee joint valgity angle,malaligment, functional status and knee joint position sense.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Twenty-nine patients (female/male: 24/5) with grade 4 osteoarthritis were included in the TKA group (study group) and 22 patients (female/male:13/9) with <grade 4 osteoarthritis were included in the control group. Systemic venous blood samples of the patients were taken to evaluate the cytokine level (IL-6, TNF-α, IL-1). The Visual Analogue Scale was used to assess pain intensity, and the WOMAC (Western Ontario and McMaster Universities Osteoarthritis Index) score was used to evaluate the functional status. Valgity and malaligment measurements were calculated using antero-posterior X ray Digital goniometer was used to evaluate the knee joint position sense (at 35, 55 and 70 degrees knee flexion angles). Measurements were taken once from patients in the control group, and twice in pre-op and post-op sixth weeks from study group.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

45 years to 70 years (ADULT, OLDER_ADULT)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Description

Inclusion Criteria:

  • Patients with grade 4 degeneration levels who had surgical indications between the ages of 45-75 were placed in the study group.
  • Patients without surgical indication, lower than 4 OA severity included in the control group

Exclusion Criteria:

  • Patients with surgical history of the ipsilateral side, neuropathic pain, loss of sensation, systemic, chronic and infectious disease were excluded from the study

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
EXPERIMENTAL: Study group
Twenty-nine patients (female/male: 24/5) with grade 4 osteoarthritis were included in the study group. These patients underwent total knee arthroplasty
Procedure: Total Knee Arthroplasty
Osteoarthritis (OA) is one of the most common chronic peripheral joint diseases increasing among the aging population.Pathogenesis is not fully known.One of the most common risk factors and causes are loss of pain and function. Knee joint osteoarthritis adversly affects the person's life quality. Total Knee Arthroplasty (TKA) is a surgical approach to restore tibiofemoral joint alignment, especially in the severe level of knee OA.
NO_INTERVENTION: Control group
Twenty-two patients (female/male:13/9) with <grade 4 osteoarthritis were included in the control group.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
