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.
When cartilage repair makes sense before knee replacementTotal knee replacement achieves over 90% long-term success, yet patients under 55 face substantially higher revision risk within 20 years. For focal cartilage damage in the mid-40s, repair offers a joint-preservation pathway suited to this earlier disease stage—provided defect size and patient profile meet defined clinical criteria.Total knee replacement achieves over 90% long-term success, yet patients under 55 face substantially higher revision risk within 20 years.

Cartilage repair or knee replacementThe choice between cartilage repair and knee replacement hinges on whether damage is focal or diffuse. Isolated defects in otherwise healthy joints can be repaired; widespread bone-on-bone osteoarthritis affecting multiple compartments requires replacement instead.The choice between cartilage repair and knee replacement hinges on whether damage is focal or diffuse.

Choosing joint preserving surgery before knee replacementOne-compartment knee wear does not automatically mean replacement is next: bracing, osteotomy and focal cartilage repair can reduce pain and delay arthroplasty when alignment and damage remain localised. Microfracture is now usually limited to very small defects, while AMIC, MACI, OATS and OCA are chosen by lesion size, depth and…One-compartment knee wear does not automatically mean replacement is next: bracing, osteotomy and focal cartilage repair can reduce pain and delay arthroplasty when alignment and damage remain localised. Microfracture is now usually limited to very small defects, while AMIC, MACI, OATS and OCA are chosen by lesion size, depth and joint health.
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...
