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

Decalcification bone scaffold is a tissue engineering scaffold with the closest biomechanics and structure of normal cartilage. The objective of the study is to evaluate the clinical efficacy of arthroscopic decalcification bone scaffold combined with microfracture in the repairment of articular cartilage defects by randomized controlled trial. Sixty patients with clinically diagnosed knee cartilage injury according to 1: 1 were divided into experimental group and control group. The experimental group will be treated with decalcification bone scaffold combined with microfracture .The control group will be treated with microfracture . The patients will be treated by the same surgeon in this study group. MRI evaluation, Lysholm score, IKDC score, Tegner score, VAS score are selected as the measures of outcome, while the blood routine, blood biochemistry, urine, CRP, ECG and other laboratory tests will be recorded inclduing the incidence of adverse events.

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.

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
Measure Description
Time Frame
Appraise of magnetic reasonance imaging
Time Frame: 5 years
Evaluate the articular cartilage postoperatively by MRI.
5 years

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
Measure Description
Time Frame
Lysholm score
Time Frame: 5 years
The Lysholm score consists of eight items including limping, locking, pain, stair climbing, use of supports, instability, swelling, and squatting. The higher values represent a better outcome.
5 years
International Knee Documentation Committee (IKDC) 2000
Time Frame: 5 years
International Knee Documentation Committee (IKDC) 2000. The higher values represent a better outcome.
5 years
Tegner activity level score
Time Frame: 5 years
The highest level of activity that you participated in before your injury and the highest level you are able to participate in currently. The higher values represent a better outcome.
5 years
Visual analogue scale
Time Frame: 5 years
The visual analogue scale or visual analog scale (VAS) is a psychometric response scale which can be used in questionnaires. It is a measurement instrument for subjective characteristics or attitudes that cannot be directly measured. When responding to a VAS item, respondents specify their level of agreement to a statement by indicating a position along a continuous line between two end-points. From 0 to 10, no pain 0, worst pain imaginable 10. The higher values represent a worse outcome.
