When knee cartilage repair is worth considering
Cartilage lacks a blood supply and cannot self-heal, but surgical or minimally invasive repair can restore focal defects in otherwise healthy joints, potentially delaying knee replacement by years or decades.Cartilage lacks a blood supply and cannot self-heal, but surgical or minimally invasive repair can restore focal defects in otherwise healthy joints, potentially delaying knee replacement by years or decades.

The cost of leaving a knee cartilage defect untreated
Knee cartilage defects do not heal because cartilage lacks blood supply; defects widen under load with each step, spreading damage to surrounding tissue and progressing towards osteoarthritis if untreated.Knee cartilage defects do not heal because cartilage lacks blood supply; defects widen under load with each step, spreading damage to surrounding tissue and progressing towards osteoarthritis if untreated.

AMIC vs MACI for knee cartilage repair
Standalone microfracture for knee cartilage defects has less than 60% survivorship at three years; AMIC adds a collagen membrane to stabilize repair, whilst MACI uses cultured chondrocytes and shows superiority in the SUMMIT trial for lesions over 3 cm².Standalone microfracture for knee cartilage defects has less than 60% survivorship at three years; AMIC adds a collagen membrane to stabilize repair, whilst MACI uses cultured chondrocytes and shows superiority in the SUMMIT trial for lesions over 3 cm².

Cartilage Specialist or General Orthopaedic Surgeon
Focal cartilage damage—treated with progressive repair techniques from injections to cell-based therapy—warrants a cartilage specialist. Widespread arthritis, fractures, or joint replacement require a general orthopaedic surgeon. Damage type and location, not pain severity, determine which specialist is appropriate.Focal cartilage damage—treated with progressive repair techniques from injections to cell-based therapy—warrants a cartilage specialist.

OATS versus mosaicplasty for knee cartilage repair
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.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.

AMIC vs microfracture for knee cartilage repair
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.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 UK
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.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.

Symptoms That Warrant a Cartilage Specialist
Articular cartilage cannot repair itself because it contains no blood vessels or nerves; defects exceeding approximately 1 cm in size tend to deteriorate rather than stabilise, and the window for joint-preserving intervention is finite.Articular cartilage cannot repair itself because it contains no blood vessels or nerves; defects exceeding approximately 1 cm in size tend to deteriorate rather than stabilise, and the window for joint-preserving intervention is finite.

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.
