Osteochondral Allograft for Ankle Cartilage DefectsLesions on the talus larger than 15mm fail with microfracture repair; osteochondral allograft instead restores the cartilage and bone using donor tissue, achieving 85% survivorship at ten years.Lesions on the talus larger than 15mm fail with microfracture repair; osteochondral allograft instead restores the cartilage and bone using donor tissue, achieving 85% survivorship at ten years.

Allograft vs autograft for large knee cartilage defectsAutograft for knee cartilage defects larger than roughly 2–4 cm² risks replacing one area of cartilage loss with another at the harvest site. Osteochondral allografts from cadaveric donors eliminate this trade-off and achieve 5-year survival of 79–87.8%.Autograft for knee cartilage defects larger than roughly 2–4 cm² risks replacing one area of cartilage loss with another at the harvest site.

How ACI and MACI differ for cartilage repairMACI pre-seeds cultured chondrocytes onto a collagen membrane fixed with fibrin glue, eliminating the sutures required in earlier ACI variants. The technique enables arthroscopic implantation and supports faster recovery than open surgical approaches.MACI pre-seeds cultured chondrocytes onto a collagen membrane fixed with fibrin glue, eliminating the sutures required in earlier ACI variants.

ChondroFiller injection vs knee replacementChondroFiller is a collagen scaffold injection that recruits the patient's own repair cells to treat focal cartilage defects. Knee replacement suits end-stage, widespread wear; the choice between them depends on imaging findings, not age.ChondroFiller is a collagen scaffold injection that recruits the patient's own repair cells to treat focal cartilage defects.

Injectable scaffold vs surgical knee cartilage repairFor focal knee cartilage defects, injectable collagen scaffolds provide a non-surgical treatment by acting as an acellular matrix that guides the patient's own progenitor cells in regenerating cartilage-like tissue, overcoming cartilage's inability to repair itself due to lacking blood supply.For focal knee cartilage defects, injectable collagen scaffolds provide a non-surgical treatment by acting as an acellular matrix that guides the patient's own progenitor cells in regenerating cartilage-like tissue, overcoming cartilage's inability to repair itself due to lacking blood supply.

When is it too late for cartilage repair?Once cartilage loss becomes generalised and surfaces contact bone, no restoration procedure works; repair is viable only for focal defects.Once cartilage loss becomes generalised and surfaces contact bone, no restoration procedure works; repair is viable only for focal defects.

Chondroplasty for knee cartilage damageChondroplasty removes loose cartilage fragments that cause catching and grinding, relieving mechanical symptoms, but does not rebuild the cartilage itself; it is palliative, not restorative.Chondroplasty removes loose cartilage fragments that cause catching and grinding, relieving mechanical symptoms, but does not rebuild the cartilage itself; it is palliative, not restorative.

Tibial Plateau Fracture Recovery Beyond One YearRecovery from tibial plateau fracture typically extends five years; at 12–24 months post-surgery, most patients have not returned to normal function and only 31% have regained meaningful sporting ability.Recovery from tibial plateau fracture typically extends five years; at 12–24 months post-surgery, most patients have not returned to normal function and only 31% have regained meaningful sporting ability.

Choosing cartilage repair pathways for knee and ankleSmall focal cartilage defects in the knee and ankle are treated differently from diffuse arthritis: first with physiotherapy and symptom control, then with repair procedures such as microfracture for lesions under about 1.0 cm², scaffold augmentation for larger defects, and OATS or osteochondral allograft for bigger or cystic lesions.Small focal cartilage defects in the knee and ankle are treated differently from diffuse arthritis: first with physiotherapy and symptom control, then with repair procedures such as microfracture for lesions under about 1.0 cm², scaffold augmentation for larger defects, and OATS or osteochondral allograft for bigger or cystic lesions.

High tibial osteotomy recovery and joint preservationHigh tibial osteotomy shifts load away from a damaged knee compartment and is best suited to younger, active patients with correctable medial osteoarthritis. Recovery takes months, full weight bearing depends on fixation and healing, and long-term success is strongest when arthritis remains localised.High tibial osteotomy shifts load away from a damaged knee compartment and is best suited to younger, active patients with correctable medial osteoarthritis.

Which knee cartilage repair fits your situationKnee cartilage repair choice is driven by defect size, bone involvement and whether treatment is single-stage or staged. OATS or mosaicplasty uses the patient's own osteochondral plugs for small focal defects of roughly 1 to 4 cm², while OCA uses donor tissue when the defect is larger, post-traumatic or involves…Knee cartilage repair choice is driven by defect size, bone involvement and whether treatment is single-stage or staged. OATS or mosaicplasty uses the patient's own osteochondral plugs for small focal defects of roughly 1 to 4 cm², while OCA uses donor tissue when the defect is larger, post-traumatic or involves significant bone loss. AMIC is a single-stage marrow stimulation with a collagen membrane; MACI takes two stages but has 15- to 17-year follow-up data, while head-to-head AMIC-vs-MACI ev...

Cartilage repair or knee replacementThe first split between cartilage repair and knee replacement is whether damage is a focal defect in an otherwise intact knee or diffuse wear across the joint. Joint-preserving treatment fits localised lesions, often in younger or active patients, with alignment, meniscus status and stability shaping the plan. Smaller focal defects…The first split between cartilage repair and knee replacement is whether damage is a focal defect in an otherwise intact knee or diffuse wear across the joint. Joint-preserving treatment fits localised lesions, often in younger or active patients, with alignment, meniscus status and stability shaping the plan. Smaller focal defects under about 2 to 4 cm² may still be treated with microfracture, but the SUMMIT trial showed MACI gave better 2-year pain and function for larger defects. OCA addresse...
