ACI or MACI for knee cartilage repairACI or MACI for knee cartilage repair
Both ACI and MACI require two operations: stage-1 biopsy yields too few chondrocytes for immediate repair, so stage-2 implantation must follow 3–6 weeks of laboratory expansion.Both ACI and MACI require two operations: stage-1 biopsy yields too few chondrocytes for immediate repair, so stage-2 implantation must follow 3–6 weeks of laboratory expansion.
MACI versus microfracture for knee cartilage repairMACI versus microfracture for knee cartilage repair
MACI outperforms microfracture for knee cartilage defects of 3 cm² or larger, according to the SUMMIT randomised trial, which found significantly greater improvements in pain and function at two years that persisted through five years.MACI outperforms microfracture for knee cartilage defects of 3 cm² or larger, according to the SUMMIT randomised trial, which found significantly greater improvements in pain and function at two years that persisted through five years.
ACI vs MACI for knee cartilage repairACI vs MACI for knee cartilage repair
MACI seeds harvested chondrocytes onto a collagen membrane secured with fibrin glue; first-generation ACI injects them as a liquid suspension under a sutured periosteal patch. This engineering difference has driven MACI's adoption: complication rates of approximately 10% versus 29%, with superior pain reduction and activity levels.MACI seeds harvested chondrocytes onto a collagen membrane secured with fibrin glue; first-generation ACI injects them as a liquid suspension under a sutured periosteal patch.

MACI vs Microfracture for Knee Cartilage RepairMACI vs Microfracture for Knee Cartilage Repair
For focal knee cartilage defects above 3 cm², MACI outperformed microfracture across all clinical measures: pain scores improved to 82.5 versus 70.9 at two years, with durability sustained at five-year follow-up.For focal knee cartilage defects above 3 cm², MACI outperformed microfracture across all clinical measures: pain scores improved to 82.5 versus 70.9 at two years, with durability sustained at five-year follow-up.
STACi vs MACI for knee cartilage repairSTACi vs MACI for knee cartilage repair
STACi performs knee cartilage repair in one operation by combining bone-marrow stem cells with patient chondrocytes on a three-dimensional scaffold — differing from MACI in cell composition and scaffold structure, though lacking randomised-trial evidence for long-term durability.STACi performs knee cartilage repair in one operation by combining bone-marrow stem cells with patient chondrocytes on a three-dimensional scaffold — differing from MACI in cell composition and scaffold structure, though lacking randomised-trial evidence for long-term durability.
ACI vs MACI for knee cartilage repairACI vs MACI for knee cartilage repair
Both ACI and MACI for knee cartilage repair follow a two-stage structure: cartilage biopsy with laboratory expansion, then implantation. The difference lies in the second stage's delivery mechanism—ACI injects expanded cells beneath a periosteal patch, while MACI pre-seeds them onto a collagen membrane secured with fibrin glue.Both ACI and MACI for knee cartilage repair follow a two-stage structure: cartilage biopsy with laboratory expansion, then implantation.

OATS and Mosaicplasty for Knee Cartilage RepairOATS and Mosaicplasty for Knee Cartilage Repair
OATS delivers genuine hyaline cartilage — the knee's native resilient material — to repair focal defects in one operation; marrow-stimulation techniques like microfracture instead produce fibrocartilage, scar-like tissue that begins to break down within two to three years under athletic demand.OATS delivers genuine hyaline cartilage — the knee's native resilient material — to repair focal defects in one operation; marrow-stimulation techniques like microfracture instead produce fibrocartilage, scar-like tissue that begins to break down within two to three years under athletic demand.
When Knee Alignment Must Come Before Cartilage RepairWhen Knee Alignment Must Come Before Cartilage Repair
Cartilage repair fails in a varus knee because the weight-bearing line runs through the damaged medial compartment instead of the joint's centre. High tibial osteotomy redirects that line toward the centre; expert guidance mandates combined surgery above 3° varus and forbids isolated repair beyond 5°.Cartilage repair fails in a varus knee because the weight-bearing line runs through the damaged medial compartment instead of the joint's centre.

When cartilage repair is the right choiceWhen cartilage repair is the right choice
Cartilage repair succeeds for a focal defect in otherwise healthy joint tissue in younger patients, but fails in diffuse arthritis. Lesion size, depth, patient age, and activity level determine the appropriate technique.Cartilage repair succeeds for a focal defect in otherwise healthy joint tissue in younger patients, but fails in diffuse arthritis.

How ACI and MACI differ for cartilage repairHow ACI and MACI differ for cartilage repair
MACI 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.

Injectable scaffold vs surgical knee cartilage repairInjectable scaffold vs surgical knee cartilage repair
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.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.
AMIC versus MACI for focal cartilage repairAMIC versus MACI for focal cartilage repair
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. 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.
