OATS mosaicplasty for sports knee cartilage repair
In a ten-year trial of athletes, osteochondral autograft transfer showed 14% treatment failure versus 38% for microfracture, a divergence emerging between years five and ten because fibrocartilage stimulated by microfracture degrades under repetitive athletic loading whilst transplanted hyaline cartilage retains structural integrity.In a ten-year trial of athletes, osteochondral autograft transfer showed 14% treatment failure versus 38% for microfracture, a divergence emerging between years five and ten because fibrocartilage stimulated by microfracture degrades under repetitive athletic loading whilst transplanted hyaline cartilage retains structural integrity.

ACI versus MACI for knee cartilage repair
Cartilage defect size on MRI drives the choice between single-stage repair (AMIC, OATS) and two-stage cell therapy (MACI): below 2–4 cm², simpler alternatives often provide comparable results; at 3 cm² or larger, MACI demonstrates superiority.Cartilage defect size on MRI drives the choice between single-stage repair (AMIC, OATS) and two-stage cell therapy (MACI): below 2–4 cm², simpler alternatives often provide comparable results; at 3 cm² or larger, MACI demonstrates superiority.

AMIC versus ACI for knee cartilage repair
AMIC completes knee cartilage repair in a single operation using bone-marrow stem cells held by a collagen scaffold; ACI requires two procedures to culture and reimplant the patient's own cartilage cells. A 2024 meta-analysis found outcomes between the two approaches broadly equivalent.AMIC completes knee cartilage repair in a single operation using bone-marrow stem cells held by a collagen scaffold; ACI requires two procedures to culture and reimplant the patient's own cartilage cells.

Knee Cartilage Repair and Preservation
Articular cartilage lacks blood vessels, so when damaged it forms fibrocartilage—a mechanically inferior scar tissue that typically deteriorates within two to three years. This biological constraint shapes every treatment option, from temporary symptom relief to procedures attempting true cartilage regeneration.Articular cartilage lacks blood vessels, so when damaged it forms fibrocartilage—a mechanically inferior scar tissue that typically deteriorates within two to three years.

When cartilage repair is the right choice
Cartilage repair is suited to younger, active patients with isolated damage in otherwise healthy joints where conservative care has not worked. It is mechanistically impossible when underlying bone is worn smooth, degeneration spans multiple compartments, or malalignment and instability persist uncorrected.Cartilage repair is suited to younger, active patients with isolated damage in otherwise healthy joints where conservative care has not worked.

Knee cartilage repair versus stem cell therapy
Established cartilage repair using autologous chondrocytes shows 10–17 year durability for focal knee defects; mesenchymal stem cell therapies have not been tested in large-scale trials against them.Established cartilage repair using autologous chondrocytes shows 10–17 year durability for focal knee defects; mesenchymal stem cell therapies have not been tested in large-scale trials against them.

Ten-Year Success Rates for OATS Mosaicplasty
Ten-year success rates for OATS mosaicplasty span 72–89% in young, active patients; failure rates drop to 12.5–14% in optimal candidates (under 40, lesion under 3 cm²) but rise to 38–40% in older patients with larger defects.Ten-year success rates for OATS mosaicplasty span 72–89% in young, active patients; failure rates drop to 12.5–14% in optimal candidates (under 40, lesion under 3 cm²) but rise to 38–40% in older patients with larger defects.

Cartilage specialist or general orthopaedic surgeon for a knee defect
Knee cartilage repair without correcting underlying malalignment results in reoperation in 47.4% of cases, versus 17.3% when alignment is corrected simultaneously — a surgical integration that general orthopaedic surgeons often omit from initial assessment and planning.Knee cartilage repair without correcting underlying malalignment results in reoperation in 47.4% of cases, versus 17.3% when alignment is corrected simultaneously — a surgical integration that general orthopaedic surgeons often omit from initial assessment and planning.

Choosing between ACI and MACI for cartilage repair
MACI cartilage grafts show 90% fill at two years but decline to 49% by ten years; 73% become fibrocartilage rather than the hyaline cartilage needed for durability.MACI cartilage grafts show 90% fill at two years but decline to 49% by ten years; 73% become fibrocartilage rather than the hyaline cartilage needed for durability.

OATS versus osteochondral allograft for large knee defects
Defect size determines which procedure: OATS, harvesting cartilage plugs from the patient's own knee, suits lesions up to 4 cm²; osteochondral allograft, using donor tissue, handles larger defects without an equivalent size limit.Defect size determines which procedure: OATS, harvesting cartilage plugs from the patient's own knee, suits lesions up to 4 cm²; osteochondral allograft, using donor tissue, handles larger defects without an equivalent size limit.

OATS or MACI for mid-size knee cartilage defects
Within the 2–4 cm² range, cartilage defects are large enough that a single plug fails to cover them, yet small enough that two repair techniques remain viable: osteochondral autograft restores cartilage and bone in one operation but creates coverage gaps, whilst matrix-induced autologous chondrocyte implantation requires two operations with laboratory…Within the 2–4 cm² range, cartilage defects are large enough that a single plug fails to cover them, yet small enough that two repair techniques remain viable: osteochondral autograft restores cartilage and bone in one operation but creates coverage gaps, whilst matrix-induced autologous chondrocyte implantation requires two operations with laboratory culture but accommodates irregular shapes without gaps.
