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.

Correlation between magnetic resonance imaging and clinical outcomes after cartilage repair surgery in the knee: J Bone Joint Surg Br. Impedes blood clot retraction while allowing for normal clotting to occur. General estimating equations were used for longitudinal statistical analysis of repeated measures.

Second, optimal MFX surgical technique was strictly obeyed in both groups. Debrided lesions quantified using 1-month posttreatment scans represented baseline values for lesion surface area and volume. Author information Copyright and License information Disclaimer.

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

Trial Detail – UK Clinical Trial Gateway

A polarized light microscopy method for accurate and reliable grading of collagen organization in cartilage repair. Check availability of results on the Clinicaltrials. This interpretation for T2 MRI and its relationship to collagen organization is substantiated by a previous statistical correlation between T2 and polarized light microscopy scoring of 38 repair tissue biopsies retrieved at 1 year posttreatment in this same study.

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. Repair tissue quantity and quality; Up to 24 months post-surgery; Adverse events related to treatment; Up to 24 months post-surgery; Economic evaluation; surgical visit, 2 weeks, 6 weeks, 3 months, 6 months, 9 months,12 months and 24 months post-surgery.

Study Design and Participants The initial 1-year trial 26 enrolled 80 patients at 26 clinical sites.

Journal List Cartilage v. Unique to this trial was the new level of evidence brought by the use of validated 3-dimensional quantitative MRI, which assessed the structural outcomes of repair tissue quantity and quality over 5 years with a high level of standardization and precision not previously achieved in a Good Clinical Practice—compliant RCT for cartilage repair.
