When OATS mosaicplasty beats other ankle cartilage repairsLesions exceeding 150 mm² require OATS mosaicplasty: marrow stimulation produces fibrocartilage that breaks down within two to three years, whilst transplanted hyaline cartilage lasts decades.Lesions exceeding 150 mm² require OATS mosaicplasty: marrow stimulation produces fibrocartilage that breaks down within two to three years, whilst transplanted hyaline cartilage lasts decades.
ChondroFiller injection after tibial plateau fractureCartilage damage from tibial plateau fractures does not repair itself, leading to progressive joint wear. ChondroFiller, a collagen scaffold injected under ultrasound, recruits the patient's own cells to generate hyaline-like repair tissue; three-year data show functional improvement of 32.4 points, exceeding the threshold for meaningful clinical benefit.Cartilage damage from tibial plateau fractures does not repair itself, leading to progressive joint wear.

OATS or microfracture for active knee patientsMicrofracture improves early but deteriorates progressively beyond two years because it deposits fibrocartilage, whilst OATS transplants intact cartilage that remains stable long-term.Microfracture improves early but deteriorates progressively beyond two years because it deposits fibrocartilage, whilst OATS transplants intact cartilage that remains stable long-term.
ChondroFiller injection cost and what affects itChondroFiller injection costs £3,000–£8,000 depending on cartilage defect size: one box £3,000, two boxes £5,500, three boxes £8,000, each including consultation, ultrasound guidance, implant, injection and six-week follow-up.ChondroFiller injection costs £3,000–£8,000 depending on cartilage defect size: one box £3,000, two boxes £5,500, three boxes £8,000, each including consultation, ultrasound guidance, implant, injection and six-week follow-up.
Osteochondral Allograft for Ankle Cartilage DefectsLesions on the talus larger than 15mm fail with microfracture repair; osteochondral allograft instead restores the cartilage and bone using donor tissue, achieving 85% survivorship at ten years.Lesions on the talus larger than 15mm fail with microfracture repair; osteochondral allograft instead restores the cartilage and bone using donor tissue, achieving 85% survivorship at ten years.
Who qualifies for ChondroFiller injectionChondroFiller recruits the patient's own cells into a collagen scaffold placed within focal cartilage defects; candidacy requires mechanical joint stability and absence of widespread degeneration.ChondroFiller recruits the patient's own cells into a collagen scaffold placed within focal cartilage defects; candidacy requires mechanical joint stability and absence of widespread degeneration.
Allograft vs autograft for large knee cartilage defectsAutograft for knee cartilage defects larger than roughly 2–4 cm² risks replacing one area of cartilage loss with another at the harvest site. Osteochondral allografts from cadaveric donors eliminate this trade-off and achieve 5-year survival of 79–87.8%.Autograft for knee cartilage defects larger than roughly 2–4 cm² risks replacing one area of cartilage loss with another at the harvest site.

How strong is ChondroFiller's clinical evidenceChondroFiller produces clinically meaningful functional improvement of approximately 30 IKDC points in knee patients, sustained at three-year follow-up, but published evidence extends no further, leaving long-term durability unproven.ChondroFiller produces clinically meaningful functional improvement of approximately 30 IKDC points in knee patients, sustained at three-year follow-up, but published evidence extends no further, leaving long-term durability unproven.
How ACI and MACI differ for cartilage repairMACI pre-seeds cultured chondrocytes onto a collagen membrane fixed with fibrin glue, eliminating the sutures required in earlier ACI variants. The technique enables arthroscopic implantation and supports faster recovery than open surgical approaches.MACI pre-seeds cultured chondrocytes onto a collagen membrane fixed with fibrin glue, eliminating the sutures required in earlier ACI variants.

ChondroFiller injection vs knee replacementChondroFiller is a collagen scaffold injection that recruits the patient's own repair cells to treat focal cartilage defects. Knee replacement suits end-stage, widespread wear; the choice between them depends on imaging findings, not age.ChondroFiller is a collagen scaffold injection that recruits the patient's own repair cells to treat focal cartilage defects.

ChondroFiller injection vs PRP for cartilage repairChondroFiller fills focal cartilage defects with a collagen scaffold; PRP modulates inflammation in diffuse wear. MRI findings, not symptoms, determine which applies.ChondroFiller fills focal cartilage defects with a collagen scaffold; PRP modulates inflammation in diffuse wear.

Injectable scaffold vs surgical knee cartilage repairFor focal knee cartilage defects, injectable collagen scaffolds provide a non-surgical treatment by acting as an acellular matrix that guides the patient's own progenitor cells in regenerating cartilage-like tissue, overcoming cartilage's inability to repair itself due to lacking blood supply.For focal knee cartilage defects, injectable collagen scaffolds provide a non-surgical treatment by acting as an acellular matrix that guides the patient's own progenitor cells in regenerating cartilage-like tissue, overcoming cartilage's inability to repair itself due to lacking blood supply.
