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.

This procedure creates a natural healing response as a result of the bleeding and clotting caused by the microfracture, restoring the lesion. Please review our privacy policy. Baseline demographic characteristics of the 80 patients were similar in the two treatment groups, including age, race, gender, BMI, smoking habits, and activity levels.

Location not identified by Google services Location data is sourced from multiple external providers and UKCTG is not responsible for and cannot guarantee the accuracy of data.

Furthermore, the trial outcomes reported here at 5 years are likely conservative estimates since 2 negative prognosticators, higher BMIs and larger lesions, were found in the enrolled patients compared with those who did not enroll in the extension study, although neither were found to be significant statistical covariates.

Support Center Support Center. Open the catalog to page 7. One 1 serious AE SAE was reported by 1 subject in the MFX group, which was moderate in severity and not related in any way to the study treatment or index knee but required surgery and radiotherapy.


Mean T2 is derived from the entire repair cartilage volume. This multi-centre randomized, controlled trial will assess the impact of BST-CarGel scaffold with microfracture versus microfracture alone on short and long term clinical benefit in patients with cartilage lesions of the femoral condyle requiring operative management.

An analysis of the quality carrgel cartilage repair studies. Microfracture for knee chondral defects: Autologous chondrocyte implantation compared with microfracture in the knee. Factors predictive of outcome 5 years after matrix-induced autologous chondrocyte implantation in the tibiofemoral joint. This investigation was performed at 26 clinical sites in Canada, Spain, and South Korea complete list is given in the Acknowledgments section.

Pain, Stiffness, and Physical Function. Durability of cartilage repair—does histology matter? Baseline Characteristics of Patients with 5-Year Data. 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. One or more of the authors received payments, either directly or indirectly i.

The trial was single-blind since the independent third party carrying out the analyses of primary endpoints was unaware of patient treatment. Go back to results. J Orthop Sports Phys Ther. Ultimately, the determination of what factors are predictive of clinical outcome following cartilage repair will be multivariate, considering the numerous patient-specific and cartilage lesion—specific variables.
