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.

When to See a Cartilage SpecialistA man in his fifties has a 35% lifetime risk of revision joint replacement surgery, versus 5% for a man in his seventies. Implants fail with time; addressable cartilage lesions in younger patients can be managed without joint replacement.A man in his fifties has a 35% lifetime risk of revision joint replacement surgery, versus 5% for a man in his seventies.

Who Qualifies for ChondroFiller InjectionChondroFiller injection is available to adults regardless of age or cartilage damage extent—from focal defects to widespread wear—across eight joints, provided the joint is mechanically stable and the patient lacks active infection, immunosuppression, or poorly controlled diabetes.ChondroFiller injection is available to adults regardless of age or cartilage damage extent—from focal defects to widespread wear—across eight joints, provided the joint is mechanically stable and the patient lacks active infection, immunosuppression, or poorly controlled diabetes.
ChondroFiller injection or knee replacement for younger patientsFor younger patients with diffuse knee wear, ChondroFiller injection places a collagen scaffold via outpatient ultrasound guidance, recruiting progenitor cells to regenerate cartilage tissue, deferring full knee replacement whilst preserving future surgical options.For younger patients with diffuse knee wear, ChondroFiller injection places a collagen scaffold via outpatient ultrasound guidance, recruiting progenitor cells to regenerate cartilage tissue, deferring full knee replacement whilst preserving future surgical options.
When a hamstring strain needs specialist careMost Grade 1 hamstring strains resolve within three weeks with self-care, but no improvement after 72 hours, spreading bruising, radiating symptoms below the knee, or competitive training demands all warrant specialist assessment to exclude a more serious tear.Most Grade 1 hamstring strains resolve within three weeks with self-care, but no improvement after 72 hours, spreading bruising, radiating symptoms below the knee, or competitive training demands all warrant specialist assessment to exclude a more serious tear.
ChondroFiller injection for ankle cartilage defectsChondroFiller is an acellular collagen scaffold injected under ultrasound into ankle cartilage defects, where it polymerises in situ to provide a structural matrix for the body's own repair cells — offering an outpatient alternative to surgery.ChondroFiller is an acellular collagen scaffold injected under ultrasound into ankle cartilage defects, where it polymerises in situ to provide a structural matrix for the body's own repair cells — offering an outpatient alternative to surgery.
Is cartilage repair right for your joint?Articular cartilage cannot heal itself: it lacks blood vessels and nerve supply, so focal defects enlarge rather than fill, requiring surgical repair when conservative management fails.Articular cartilage cannot heal itself: it lacks blood vessels and nerve supply, so focal defects enlarge rather than fill, requiring surgical repair when conservative management fails.
Why ChondroFiller injection differs from cartilage surgeryCartilage surgery is subtractive — it debrids bone and rebuilds upward; ChondroFiller injection is additive, depositing a collagen scaffold directly over worn cartilage without arthroscopy or debridement, and works where surgical repair cannot.Cartilage surgery is subtractive — it debrids bone and rebuilds upward; ChondroFiller injection is additive, depositing a collagen scaffold directly over worn cartilage without arthroscopy or debridement, and works where surgical repair cannot.
ChondroFiller Injection for Post-Traumatic Knee Cartilage DamageCartilage damage from knee fractures cannot heal spontaneously and carries elevated osteoarthritis risk; ChondroFiller, an injectable collagen scaffold, recruits the patient's own stem cells to repair these focal defects.Cartilage damage from knee fractures cannot heal spontaneously and carries elevated osteoarthritis risk; ChondroFiller, an injectable collagen scaffold, recruits the patient's own stem cells to repair these focal defects.
Single-stage cartilage repair versus ACI and MACISTACI harvests and implants cartilage within a single theatre session, combining it with bone-marrow cells to stimulate repair; conventional ACI and MACI require two procedures separated by six to eight weeks of external cell culture.STACI harvests and implants cartilage within a single theatre session, combining it with bone-marrow cells to stimulate repair; conventional ACI and MACI require two procedures separated by six to eight weeks of external cell culture.
When Achilles tendinopathy needs specialist assessmentAchilles tendinopathy causes a gradual ache that worsens with rest; eccentric calf loading is the first-line treatment. If meaningful improvement has not emerged by 12 weeks, specialist assessment is warranted.Achilles tendinopathy causes a gradual ache that worsens with rest; eccentric calf loading is the first-line treatment.
