Weight-bearing Recommendation After Replacement of the Hip or Knee Joint

April 4, 2016 updated by: Thoralf R Liebs, Verein zur Förderung der Rehabilitationsforschung in Schleswig-Holstein

A Randomized Trial of Weight-bearing Recommendations After Total Hip or Total Knee Arthroplasty

Despite the widespread use of total hip and knee arthroplasty, there is a notable lack of consensus regarding postoperative treatment, mostly because of the lack of well-designed studies testing the efficacy and effectiveness of such practices. In particular, there are no evidence-based recommendations on the amount of weight that the patient should be advised to bear on the operated leg after the operation.

Study Overview

Status

Status

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.

Study Type

Enrollment

Enrollment

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.

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.

Arms and Interventions

Participant Group / Arm

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: weight-bearing recommendation
Weight-bearing recommendation after THA and TKA
Behavioral: Recommend full weight-bearing
The full weight-bearing group is trained in 4-point gait with crutches and is recommended to put as much weight as tolerated on the leg on which surgery has been performed, immediately after surgery
Behavioral: Recommend parital weight-bearing
The partial weight-bearing group is trained in 3-point gait with crutches and is instructed to limit weight-bearing of the affected leg to 20kg for a period of six-weeks. Scales are used to train these participants not to exceed 20kg

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.
Outcome Measure
Time Frame
Physical function, measured by means of the Western Ontario and McMaster universities (WOMAC) osteoarthritis index
Time Frame: Baseline, 3, 6, 12 and 24-months after surgery
Baseline, 3, 6, 12 and 24-months after surgery

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Time Frame
Leg specific stiffness and pain, both measured by the WOMAC.
Time Frame: Baseline, 3, 6, 12 and 24-months after surgery
Baseline, 3, 6, 12 and 24-months after surgery
Physical component summary of the SF-36
Time Frame: Baseline, 3, 6, 12 and 24-months after surgery
Baseline, 3, 6, 12 and 24-months after surgery
Lequesne Hip resp. Knee Score
Time Frame: Baseline, 3, 6, 12 and 24-months after surgery
Baseline, 3, 6, 12 and 24-months after surgery
