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.

Approximately participants with full-thickness grade III and IV cartilage lesions will be randomised in a 1: One or more of the authors received payments, either directly or indirectly i. 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.

Quantitative T2 mapping of matrix-associated autologous chondrocyte transplantation at 3 Tesla: Which measures symptoms and disabilities most important to postoperative articular cartilage repair patients?

Some have been validated but are insensitive and incomplete. Scores have maximum change of 50 for Pain, 20 for Stiffness, and for Function.


Secondary and Tertiary Outcomes Clinical benefit was evaluated as a secondary outcome at initiation, 2, 3, 4, and 5 years posttreatment using the WOMAC questionnaire consisting of 3 subscales: Lower numbers represent better outcomes. National Center for Biotechnology InformationU.

Steps can be done by bzt non-sterile nurse while the lesion is being surgically prepared. Baseline demographic characteristics of the 80 patients were similar in the two treatment groups, including age, race, gender, BMI, smoking habits, and activity levels.

Screening and enrollment into the extension study took place from March to October and the 5-year follow-up was concluded in February A polarized light microscopy method for accurate and reliable grading of collagen organization in cartilage repair. Vst full description of the methodology used in the original 1-year multicenter RCT https: Location data is sourced from multiple external providers and UKCTG is not responsible for and cannot guarantee the accuracy of data.

None of the characteristics were found to be significant covariates leading to bias during bsy analyses, despite reports that clinical outcomes after microfracture are age dependent.

Food and Drug Administration. Journal List Cartilage v. Customized bzt resolution pulse sequences specific for morphological or T2 relaxation time analyses of regions of interest were used.


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. This procedure creates a natural healing response as a result of the bleeding and clotting caused by the microfracture, restoring the lesion.

When it did occur, it was linked to a predisposing factor e. Design The international randomized controlled trial enrolled 80 patients, aged 18 to 55 years, with grade III or IV focal lesions on the femoral condyles.
