OATS versus mosaicplasty for knee cartilage repairOATS and mosaicplasty are the same surgical technique applied at different scales: OATS transfers a single cartilage plug for knee defects under 2 cm², mosaicplasty tiles smaller grafts across 2–4 cm² lesions.OATS and mosaicplasty are the same surgical technique applied at different scales: OATS transfers a single cartilage plug for knee defects under 2 cm², mosaicplasty tiles smaller grafts across 2–4 cm² lesions.
ChondroFiller IKDC and MOCART scoresChondroFiller patients' functional-outcome scores (IKDC) gain approximately 30 points within 12 months, rising from ~48 to ~80, whilst structural MRI (MOCART) markers advance from 65 to 81–84 — dual tracks converging on tissue repair and restored joint function.ChondroFiller patients' functional-outcome scores (IKDC) gain approximately 30 points within 12 months, rising from ~48 to ~80, whilst structural MRI (MOCART) markers advance from 65 to 81–84 — dual tracks converging on tissue repair and restored joint function.
OCA or MACI for large knee cartilage defectsWhen subchondral bone is damaged alongside large knee cartilage defects, OCA — a single-stage transplant of donor bone and cartilage — is the preferred choice; MACI, which implants cultured cells, cannot restore bone stock once lost.When subchondral bone is damaged alongside large knee cartilage defects, OCA — a single-stage transplant of donor bone and cartilage — is the preferred choice; MACI, which implants cultured cells, cannot restore bone stock once lost.
Why ChondroFiller requires a specialist injection pathwayChondroFiller, a collagen matrix, self-polymerises within three to five minutes of injection; needle placement under ultrasound guidance must therefore be exact, as repositioning becomes impossible once gelation begins and structural repair unfolds over six to twelve months.ChondroFiller, a collagen matrix, self-polymerises within three to five minutes of injection; needle placement under ultrasound guidance must therefore be exact, as repositioning becomes impossible once gelation begins and structural repair unfolds over six to twelve months.
Osteochondral Allograft for Post-Traumatic Knee DefectsWhen post-traumatic knee injury damages both cartilage and underlying bone, osteochondral allograft transplants provide a single-stage solution that other repair methods cannot match. Roughly 75–82% of patients return to sport; grafts show 87% survival at five years, declining to 68% at twenty.When post-traumatic knee injury damages both cartilage and underlying bone, osteochondral allograft transplants provide a single-stage solution that other repair methods cannot match.

ChondroFiller NHS status and private access in the UKChondroFiller, an ultrasound-guided collagen scaffold that improves IKDC knee scores by roughly 30 points over 12 months, is unavailable on the NHS not for safety reasons but because it has not undergone formal commissioning appraisal. Private UK access costs £3,000–£9,500.ChondroFiller, an ultrasound-guided collagen scaffold that improves IKDC knee scores by roughly 30 points over 12 months, is unavailable on the NHS not for safety reasons but because it has not undergone formal commissioning appraisal.

MACI versus microfracture for knee cartilage repairMACI 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.
ChondroFiller injection vs surgery for focal knee cartilageAn ultrasound-guided collagen injection activates the joint's own regenerative cells to repair focal knee cartilage defects; 70–85% of treated patients report meaningful symptom relief within three to five years.An ultrasound-guided collagen injection activates the joint's own regenerative cells to repair focal knee cartilage defects; 70–85% of treated patients report meaningful symptom relief within three to five years.
ChondroFiller Injection Specialists in the UKAcross 19,000+ treated cases worldwide, ChondroFiller has a complication rate of 0.06%; 70–85% of patients with focal cartilage defects achieve meaningful symptom relief over 3–5 years through a collagen scaffold that recruits the patient's own repair cells.Across 19,000+ treated cases worldwide, ChondroFiller has a complication rate of 0.06%; 70–85% of patients with focal cartilage defects achieve meaningful symptom relief over 3–5 years through a collagen scaffold that recruits the patient's own repair cells.
AMIC vs microfracture for knee cartilage repairBoth AMIC and microfracture improve pain and function in the first two years; beyond that point, microfracture outcomes progressively deteriorate whilst AMIC maintains stable gains through a decade of follow-up.Both AMIC and microfracture improve pain and function in the first two years; beyond that point, microfracture outcomes progressively deteriorate whilst AMIC maintains stable gains through a decade of follow-up.
ACI knee cartilage repair in the UKACI harvests a patient's own cartilage cells, cultures them to roughly 20 times their original number, then implants them in a second operation; NHS funding applies only to patients with defects over 2 cm², no prior cartilage repair, minimal arthritis, and access to a specialist centre.ACI harvests a patient's own cartilage cells, cultures them to roughly 20 times their original number, then implants them in a second operation; NHS funding applies only to patients with defects over 2 cm², no prior cartilage repair, minimal arthritis, and access to a specialist centre.
How long ChondroFiller results lastChondroFiller's collagen scaffold biodegrades within 6–24 months, yet provides lasting clinical benefit by recruiting the patient's own cells to form repair tissue; 70–85% of well-selected patients maintain meaningful symptom relief at three to five years.ChondroFiller's collagen scaffold biodegrades within 6–24 months, yet provides lasting clinical benefit by recruiting the patient's own cells to form repair tissue; 70–85% of well-selected patients maintain meaningful symptom relief at three to five years.
