ChondroFiller vs Liquid Cartilage for focal cartilage defectsAn injectable collagen scaffold sets into a gel at body temperature and recruits the body's own progenitor cells to repair cartilage over 12–24 months. ChondroFiller is the device name; Liquid Cartilage denotes the same scaffold combined with the patient's own mesenchymal cells in a single appointment.An injectable collagen scaffold sets into a gel at body temperature and recruits the body's own progenitor cells to repair cartilage over 12–24 months.

ChondroFiller injection versus knee replacement for focal defectsChondroFiller, a gelling collagen scaffold that recruits the patient's own cells to repair cartilage, suits isolated focal defects; knee replacement addresses widespread multi-compartment osteoarthritis.ChondroFiller, a gelling collagen scaffold that recruits the patient's own cells to repair cartilage, suits isolated focal defects; knee replacement addresses widespread multi-compartment osteoarthritis.

ChondroFiller injection for knee cartilage defectsThe injected collagen scaffold gels in place and recruits the body's own progenitor cells to repair the cartilage defect without surgery or general anaesthetic. Functional scores improve from 48 to 80 on the IKDC scale over three years in independent European cohorts, with most of that improvement within six months.The injected collagen scaffold gels in place and recruits the body's own progenitor cells to repair the cartilage defect without surgery or general anaesthetic.

Cartilage specialist or general orthopaedic surgeon for a knee defectKnee 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.

MACI recovery and return to sportMACI recovery takes twelve to eighteen months before high-impact sport. Most patients return to some sport, but only one-third reach their pre-injury level — a gap significantly driven by kinesiophobia, which clinical teams can screen and address through sports psychology support.MACI recovery takes twelve to eighteen months before high-impact sport.

OATS versus osteochondral allograft for large knee defectsDefect 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.

When knee cartilage repair is worth consideringCartilage 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 untreatedKnee 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.

How defect size and age decide OATS or OCADefect size determines whether focal cartilage repair uses autograft (OATS, harvested from the patient's own knee) or donor allograft (OCA): below 2 cm², autograft is viable; above 4 cm², only allograft remains before arthroplasty.Defect size determines whether focal cartilage repair uses autograft (OATS, harvested from the patient's own knee) or donor allograft (OCA): below 2 cm², autograft is viable; above 4 cm², only allograft remains before arthroplasty.

Who qualifies for MACI knee surgeryMACI grows hyaline-like cartilage from the patient's own cells and maintains superior pain and function scores at five years, unlike microfracture, whose fibrocartilage typically deteriorates within two to three years.MACI grows hyaline-like cartilage from the patient's own cells and maintains superior pain and function scores at five years, unlike microfracture, whose fibrocartilage typically deteriorates within two to three years.
