OATS for Osteochondral Lesions of the TalusLesions larger than approximately 150 mm² fail bone marrow stimulation treatment 97% of the time. OATS transplants genuine hyaline cartilage to replace the weakening fibrocartilage scar that microfracture produces in larger defects.Lesions larger than approximately 150 mm² fail bone marrow stimulation treatment 97% of the time.

Which specialist to see for shoulder impingement painShoulder impingement is degenerative tendon wear, not acute inflammation, which explains why anti-inflammatory drugs fail and recovery takes months, not weeks.Shoulder impingement is degenerative tendon wear, not acute inflammation, which explains why anti-inflammatory drugs fail and recovery takes months, not weeks.

ACI for Ankle Cartilage DefectsMicrofracture produces fibrocartilage that deteriorates within two to three years for ankle cartilage lesions over 15 mm in diameter; autologous chondrocyte implantation regenerates more durable, hyaline-like cartilage that more closely resembles native tissue for larger defects.Microfracture produces fibrocartilage that deteriorates within two to three years for ankle cartilage lesions over 15 mm in diameter; autologous chondrocyte implantation regenerates more durable, hyaline-like cartilage that more closely resembles native tissue for larger defects.

Who Qualifies for OATS Knee Cartilage RepairOATS and mosaicplasty repair focal knee cartilage defects of 1–4 cm² with hyaline cartilage in a single operation; suitable for physically active patients aged 16–50, both achieve return to sport in 66–91% of cases.OATS and mosaicplasty repair focal knee cartilage defects of 1–4 cm² with hyaline cartilage in a single operation; suitable for physically active patients aged 16–50, both achieve return to sport in 66–91% of cases.

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.

OCA vs MACI for large knee cartilage defectsMACI (matrix-induced autologous chondrocyte implantation) is a surface repair requiring intact subchondral bone; osteochondral allograft (OCA) replaces both cartilage and bone. When knee cartilage defects breach underlying bone, OCA addresses what MACI cannot.MACI (matrix-induced autologous chondrocyte implantation) is a surface repair requiring intact subchondral bone; osteochondral allograft (OCA) replaces both cartilage and bone.

Who treats a rotator cuff tear in the UKMany NHS trusts refer rotator cuff tear cases first to an Extended Scope Practitioner — a senior physiotherapist who can order imaging, administer injections, and refer directly to a surgeon — rather than directly to an orthopaedic consultant. This deliberate pathway removes administrative steps rather than adding them.Many NHS trusts refer rotator cuff tear cases first to an Extended Scope Practitioner — a senior physiotherapist who can order imaging, administer injections, and refer directly to a surgeon — rather than directly to an orthopaedic consultant.

How single-stage ACI differs from MACIMACI repairs cartilage defects over two operations, with weeks between them for external cell expansion; STACi compresses the entire process—harvesting, processing, and implantation—into a single surgical session.MACI repairs cartilage defects over two operations, with weeks between them for external cell expansion; STACi compresses the entire process—harvesting, processing, and implantation—into a single surgical session.

ACI or MACI for knee cartilage repairBoth ACI and MACI require two operations: stage-1 biopsy yields too few chondrocytes for immediate repair, so stage-2 implantation must follow 3–6 weeks of laboratory expansion.Both ACI and MACI require two operations: stage-1 biopsy yields too few chondrocytes for immediate repair, so stage-2 implantation must follow 3–6 weeks of laboratory expansion.
