Single-stage vs two-stage ACI for cartilage repairTraditional two-stage ACI involves two general anaesthetics separated by a four-to-six-week cell culture period; STACI performs both stages in a single theatre session, requiring one general anaesthetic and eliminating the inter-stage gap.Traditional two-stage ACI involves two general anaesthetics separated by a four-to-six-week cell culture period; STACI performs both stages in a single theatre session, requiring one general anaesthetic and eliminating the inter-stage gap.

Who qualifies for ChondroFiller Liquid Cartilage injectionChondroFiller is an outpatient ultrasound-guided injection—not surgery—of acellular collagen that recruits the patient's own progenitor cells to regenerate cartilage damage, without upper age or defect-size limits.ChondroFiller is an outpatient ultrasound-guided injection—not surgery—of acellular collagen that recruits the patient's own progenitor cells to regenerate cartilage damage, without upper age or defect-size limits.

What ChondroFiller's CE approval means for UK patientsChondroFiller recruits the body's progenitor cells to repair focal cartilage defects, achieving symptom relief in 70–85% of selected patients, though it offers no benefit for widespread osteoarthritis.ChondroFiller recruits the body's progenitor cells to repair focal cartilage defects, achieving symptom relief in 70–85% of selected patients, though it offers no benefit for widespread osteoarthritis.

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 a ChondroFiller injectionChondroFiller targets ICRS Grade III–IV cartilage damage, where more than half the cartilage is lost or bone is exposed. Delivered as an ultrasound-guided outpatient injection, the collagen scaffold recruits the patient's own progenitor cells to initiate repair.ChondroFiller targets ICRS Grade III–IV cartilage damage, where more than half the cartilage is lost or bone is exposed.

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.

Is OATS knee surgery worth itCartilage damage beyond a certain point cannot self-repair. OATS transplants healthy cartilage plugs to replace it, with 85–93% achieving clinical success and improvements sustained at ten and twenty years, though 10–15% experience persistent donor-site pain.Cartilage damage beyond a certain point cannot self-repair.

ChondroFiller combined with BMAC for cartilage repairA collagen scaffold traps bone-marrow stem cells in cartilage defects, preventing the clearance by synovial fluid that normally occurs within hours and enabling repair in a single outpatient appointment without surgery.A collagen scaffold traps bone-marrow stem cells in cartilage defects, preventing the clearance by synovial fluid that normally occurs within hours and enabling repair in a single outpatient appointment without surgery.
