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.

When is it too late for cartilage repair?Once cartilage loss becomes generalised and surfaces contact bone, no restoration procedure works; repair is viable only for focal defects.Once cartilage loss becomes generalised and surfaces contact bone, no restoration procedure works; repair is viable only for focal defects.
ChondroFiller availability across EuropeChondroFiller is an injectable collagen scaffold that gels in place and recruits the patient's own cells to repair cartilage defects. CE-marked Class III in Europe, it is available in UK private clinics under the brand Liquid Cartilage™, from £3,000 per injection.ChondroFiller is an injectable collagen scaffold that gels in place and recruits the patient's own cells to repair cartilage defects.

AMIC versus MACI for focal cartilage repairAMIC repairs focal cartilage defects in one operation: drilling channels into damaged cartilage releases a blood clot rich in stem cells, which a collagen membrane then stabilises and concentrates to guide tissue repair. A 2025 trial found it equivalent to MACI at two years.AMIC repairs focal cartilage defects in one operation: drilling channels into damaged cartilage releases a blood clot rich in stem cells, which a collagen membrane then stabilises and concentrates to guide tissue repair.

ChondroFiller durability vs Arthrosamid and hyaluronic acidChondroFiller's collagen scaffold breaks down in six to twenty-four months, but the clinical benefit lasts one to five years or longer because the material recruits the patient's own progenitor cells to support cartilage repair, not to act as permanent filling.ChondroFiller's collagen scaffold breaks down in six to twenty-four months, but the clinical benefit lasts one to five years or longer because the material recruits the patient's own progenitor cells to support cartilage repair, not to act as permanent filling.
Chondroplasty for knee cartilage damageChondroplasty removes loose cartilage fragments that cause catching and grinding, relieving mechanical symptoms, but does not rebuild the cartilage itself; it is palliative, not restorative.Chondroplasty removes loose cartilage fragments that cause catching and grinding, relieving mechanical symptoms, but does not rebuild the cartilage itself; it is palliative, not restorative.
ChondroFiller success rates in practiceChondroFiller, which recruits a patient's own cells to fill cartilage defects, produces meaningful pain reduction and improved joint function in 70–85% of patients within one to five years; but success depends on selecting younger patients with focal defects in otherwise healthy joints.ChondroFiller, which recruits a patient's own cells to fill cartilage defects, produces meaningful pain reduction and improved joint function in 70–85% of patients within one to five years; but success depends on selecting younger patients with focal defects in otherwise healthy joints.
Who benefits from an unloader knee braceUnloader braces use three-point pressure to shift load away from damaged cartilage. They work only for single-compartment osteoarthritis, and success depends more on professional fitting and follow-up than the device itself.Unloader braces use three-point pressure to shift load away from damaged cartilage.

Choosing ACI, MACI or single‑stage cell surgeryACI and MACI are two-stage repairs for localised full-thickness cartilage defects, while single-stage techniques place cells or cell-rich material into the defect in one operation. MACI has the strongest long-term follow-up, but single-stage methods still rest mainly on smaller, less comparable series.ACI and MACI are two-stage repairs for localised full-thickness cartilage defects, while single-stage techniques place cells or cell-rich material into the defect in one operation.

Do you need a knee or ankle cartilage specialistPersistent knee or ankle pain, swelling or loss of function despite simple self-care usually warrants orthopaedic assessment; a cartilage or joint-preservation specialist is most useful when MRI shows a focal defect in a relatively healthy joint, while diffuse wear-and-tear or advanced arthritis usually suits a general orthopaedic or sports surgeon.Persistent knee or ankle pain, swelling or loss of function despite simple self-care usually warrants orthopaedic assessment; a cartilage or joint-preservation specialist is most useful when MRI shows a focal defect in a relatively healthy joint, while diffuse wear-and-tear or advanced arthritis usually suits a general orthopaedic or sports surgeon.
