Clinical Evaluation of dCELL® ACL Scaffold for Reconstruction of the Anterior Cruciate Ligament

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government. Read our disclaimer for details. Identifier: NCT02540811
Recruitment Status : Active, not recruiting

Brief Summary:
The safety and performance of dCELL® ACL Scaffold will be evaluated in 40 patients who have been implanted with the investigational product following a ruptured anterior cruciate ligament (ACL) of the knee.

Condition or disease Intervention/treatment Phase
Knee Injuries Device: dCELL® ACL Scaffold Not Applicable

Detailed Description:

The dCELL® ACL Scaffold is a novel device manufactured from porcine tissue using a patented variation of Tissue Regenix's platform technology to render the tissue biocompatible and free from cellular material, providing a biological scaffold that is safe for human implantation whilst preserving the biomechanical properties.

The device is used to reconstruct traumatic ACL tears to help restore normal knee function and therefore prevent further wear of the cartilage and future damage.

Arm Intervention/treatment
Experimental: dCELL® ACL Scaffold Device: dCELL® ACL Scaffold

Primary Outcome Measures :
  1. Arthrometric measurement of knee joint laxity [ Time Frame: 24 months ]
    Comparison of the magnitude of side-to-side differences in mm between the treated knee and the opposite normal knee using an arthrometric ligament testing device

  2. Number of Participants With Treatment-Related Adverse Events [ Time Frame: 24 months ]
    The frequency and seriousness of any adverse events or adverse device effects will be assessed

Secondary Outcome Measures :
  1. Outcome measure questionnaire of knee functional improvement in terms of symptoms, sport activities and ability to function [ Time Frame: 24 months ]
    Patient's subjective score of 1 to 100 points, with 100 implying the best results and 1 the worst results

  2. Evidence of integration of the investigational product by MRI [ Time Frame: 24 months ]
    Changes to the articular cartilage or joint space at follow up time points compared to pre-surgery
