Implication

Randomized trial demonstrates superior cartilage filling and tissue quality with BST-CarGel in knee cartilage lesions, indicating enhanced structural repair over standard microfracture.

Key Points

To evaluate the structural repair quality and clinical outcomes of BST-CarGel combined with microfracture versus microfracture alone for knee cartilage lesions.
International, multicenter randomized controlled trial enrolling 80 patients aged 18–55 years with a single symptomatic focal femoral condyle lesion.
Patients were randomized to BST-CarGel combined with microfracture (n = 41) or microfracture alone (n = 39) with a 12-month follow-up.
Repair tissue quantity (lesion filling) and quality (T2 relaxation time) were assessed at 12 months via quantitative 3D MRI, alongside WOMAC clinical scores and SF-36 safety evaluations.
BST-CarGel achieved statistically superior lesion filling at 12 months compared with microfracture alone (92.8% ± 2.0% vs 85.2% ± 2.1%, p = 0.011).
BST-CarGel produced more hyaline cartilage-like repair tissue, demonstrated by significantly lower T2 relaxation values (70.5 ± 4.5 ms vs 85.0 ± 4.9 ms, p = 0.033).
Both treatment groups demonstrated significant improvements from baseline in WOMAC scores for pain, stiffness, and function (p < 0.0001), with equivalent clinical benefits and safety profiles.
