OATS or OCA for osteochondral knee repairDefect size is the primary determinant in osteochondral knee repair: lesions under 2–4 cm² are treated with OATS (autograft plugs), larger defects with OCA (fresh donor tissue), a distinction reflecting the limits of safe tissue harvest from the patient's own knee.Defect size is the primary determinant in osteochondral knee repair: lesions under 2–4 cm² are treated with OATS (autograft plugs), larger defects with OCA (fresh donor tissue), a distinction reflecting the limits of safe tissue harvest from the patient's own knee.

ChondroFiller injection for hip cartilage defectsChondroFiller is a liquid collagen scaffold injected into the hip, where it gels at body temperature and recruits the patient's own cells to progressively repair damaged cartilage. Delivered as an outpatient ultrasound-guided injection under local anaesthetic, it suits isolated cartilage defects where surrounding tissue remains intact.ChondroFiller is a liquid collagen scaffold injected into the hip, where it gels at body temperature and recruits the patient's own cells to progressively repair damaged cartilage.

ChondroFiller on the NHS or privately in the UKChondroFiller is a cell-free collagen hydrogel injected under ultrasound guidance as an outpatient procedure to recruit the body's own repair cells for focal cartilage defects; it is unavailable on the NHS as it has not entered the NICE appraisal process, but is accessible privately through self-referral.ChondroFiller is a cell-free collagen hydrogel injected under ultrasound guidance as an outpatient procedure to recruit the body's own repair cells for focal cartilage defects; it is unavailable on the NHS as it has not entered the NICE appraisal process, but is accessible privately through self-referral.

ChondroFiller or Arthrosamid for knee cartilageChondroFiller and Arthrosamid are not interchangeable fillers — they address different anatomical targets within the knee. ChondroFiller is a collagen scaffold placed directly on the cartilage surface to recruit the patient's own repair cells; Arthrosamid is a permanent hydrogel in the synovial lining that provides mechanical cushioning.ChondroFiller and Arthrosamid are not interchangeable fillers — they address different anatomical targets within the knee.

When ankle sprain needs more than A&EA&E correctly rules out fractures but cannot assess ligament damage; most ankle sprain patients leave with rest-ice advice alone, yet structured physiotherapy reduces 12-month re-injury rates by roughly 40 per cent compared with routine care.A&E correctly rules out fractures but cannot assess ligament damage; most ankle sprain patients leave with rest-ice advice alone, yet structured physiotherapy reduces 12-month re-injury rates by roughly 40 per cent compared with routine care.

ChondroFiller repeat injections and long-term repairChondroFiller recruits the patient's progenitor cells into a collagen scaffold that degrades over 12–18 months whilst repair tissue develops; 81% of hip patients achieved good or excellent outcomes at three to five years, but success depends heavily on whether osteoarthritis is early-stage or advanced.ChondroFiller recruits the patient's progenitor cells into a collagen scaffold that degrades over 12–18 months whilst repair tissue develops; 81% of hip patients achieved good or excellent outcomes at three to five years, but success depends heavily on whether osteoarthritis is early-stage or advanced.

Knee Cartilage Repair and PreservationArticular 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.

Is MACI Knee Surgery Worth It?MACI harvests, cultures, and implants the patient's own cartilage cells across two surgeries weeks apart. It delays knee replacement—7.4% progression over a decade—but requires 12–18 months of recovery and works best for younger patients with focal defects of 3 cm² or more.MACI harvests, cultures, and implants the patient's own cartilage cells across two surgeries weeks apart.
