Blinded MRI analysis demonstrated that BST-CarGel®-treated patients showed a significantly greater treatment effect for lesion filling (P = ) over 5 years. BST-CarGel is an advanced bioscaffold technology for enhancing cartilage regeneration. BST-CarGel was developed to stabilize the blood clot in the cartilage lesion by dispersing a soluble and adhesive polymer scaffold containing chitosan.

Patients were randomized 1: Clinical efficacy of the microfracture technique for articular cartilage repair in the cargfl Approximately participants with full-thickness grade III and IV cartilage lesions will be randomised in a 1: T2 or transverse relaxation time is well known to be sensitive to, and highly dependent on, the extracellular cartilage matrix and particularly the collagen network structure, orientation, as well as macromolecular concentration, and tissue hydration.

cragel The equivalent clinical improvements found in this trial add to accumulating evidence that when performed properly, 9 microfracture can effectively improve clinical caryel and function for the mid- to long-term despite the widely purported clinical outcome expectancy of 2 to 3 years linked to a mechanically deficient fibrocartilaginous repair tissue and excessive intralesional bony overgrowth.

J Bone Joint Surg Br ; Clearly, more and longer studies are required both with structural tools and patient-reported clinical measures that are specific enough cagrel detect improvements following cartilage repair before the relationship between clinical and structural outcomes will emerge. Values represent least squares means adjusted for lesion volume and the standard error. The same follow-up procedures and outcome methodologies were applied in the 5-year extension protocol https: Thank you for helping us grow and improving medical research!

Durability of cartilage repair—does histology matter? All subjects who participated in the initial 1-year trial were asked to provide written informed consent prior to study activities to be part of this extension study, which was approved by the institutional review boards at each of the clinical sites prior to initiation of activities.

BST-CarGel does not interfere with the normal clotting process; however, it enables a prolonged healing time due to the increased stabilization of the clot within the lesion and the inhibition of clot retraction.
