Knee Cartilage Repair and PreservationArticular cartilage lacks blood vessels, so when damaged it forms fibrocartilage—a mechanically inferior scar tissue that typically deteriorates within two to three years. This biological constraint shapes every treatment option, from temporary symptom relief to procedures attempting true cartilage regeneration.Articular cartilage lacks blood vessels, so when damaged it forms fibrocartilage—a mechanically inferior scar tissue that typically deteriorates within two to three years.

Is MACI Knee Surgery Worth It?MACI harvests, cultures, and implants the patient's own cartilage cells across two surgeries weeks apart. It delays knee replacement—7.4% progression over a decade—but requires 12–18 months of recovery and works best for younger patients with focal defects of 3 cm² or more.MACI harvests, cultures, and implants the patient's own cartilage cells across two surgeries weeks apart.

Ultrasound guidance in ChondroFiller hip injectionUltrasound-guided hip injection achieves 89% placement accuracy versus 58% for landmark guidance — a gap that determines whether ChondroFiller, a collagen scaffold that works only when positioned within a focal cartilage defect, succeeds or the material is simply resorbed.Ultrasound-guided hip injection achieves 89% placement accuracy versus 58% for landmark guidance — a gap that determines whether ChondroFiller, a collagen scaffold that works only when positioned within a focal cartilage defect, succeeds or the material is simply resorbed.

Can ChondroFiller delay joint replacement?An injectable collagen scaffold called ChondroFiller recruits the patient's own repair cells to regenerate cartilage in 30–45 minutes. Clinical trials show IKDC score improvements averaging 32.4 points — nearly double the threshold for clinically significant change — when administered in early focal cartilage damage where joint space remains.An injectable collagen scaffold called ChondroFiller recruits the patient's own repair cells to regenerate cartilage in 30–45 minutes.

How long osteochondral allografts lastFresh osteochondral allografts achieve approximately 82–86% graft survival at five years and roughly 70% beyond 20 years; outcomes depend substantially on patient BMI, prior knee surgery, and adherence to structured post-operative support.Fresh osteochondral allografts achieve approximately 82–86% graft survival at five years and roughly 70% beyond 20 years; outcomes depend substantially on patient BMI, prior knee surgery, and adherence to structured post-operative support.

ChondroFiller vs Liquid Cartilage for focal cartilage defectsAn injectable collagen scaffold sets into a gel at body temperature and recruits the body's own progenitor cells to repair cartilage over 12–24 months. ChondroFiller is the device name; Liquid Cartilage denotes the same scaffold combined with the patient's own mesenchymal cells in a single appointment.An injectable collagen scaffold sets into a gel at body temperature and recruits the body's own progenitor cells to repair cartilage over 12–24 months.

ChondroFiller™ durability compared with ArthrosamidChondroFiller™ recruits the patient's own progenitor cells to build new cartilage tissue within a collagen scaffold. Three-year published follow-up shows mean IKDC scores of 80 — a 32.4-point improvement from baseline — with durability reported to extend beyond five years.ChondroFiller™ recruits the patient's own progenitor cells to build new cartilage tissue within a collagen scaffold.

ChondroFiller injection for knee cartilage defectsThe injected collagen scaffold gels in place and recruits the body's own progenitor cells to repair the cartilage defect without surgery or general anaesthetic. Functional scores improve from 48 to 80 on the IKDC scale over three years in independent European cohorts, with most of that improvement within six months.The injected collagen scaffold gels in place and recruits the body's own progenitor cells to repair the cartilage defect without surgery or general anaesthetic.
