When knee pain needs an orthopaedic assessmentMost knee pain settles with rest and physiotherapy; the threshold for orthopaedic assessment is persistent dysfunction despite weeks of conservative care, or acute structural changes—and assessment maps options rather than commits to surgery.Most knee pain settles with rest and physiotherapy; the threshold for orthopaedic assessment is persistent dysfunction despite weeks of conservative care, or acute structural changes—and assessment maps options rather than commits to surgery.

High tibial osteotomy as a first step in knee preservationHigh tibial osteotomy repositions the tibia to shift weight-bearing from damaged inner knee cartilage to the healthier outer compartment. For younger, active patients, the procedure preserves the natural joint and potentially extends its working life by a decade or more.High tibial osteotomy repositions the tibia to shift weight-bearing from damaged inner knee cartilage to the healthier outer compartment.

ChondroFiller vs Liquid Cartilage for focal cartilage defectsAn injectable collagen scaffold sets into a gel at body temperature and recruits the body's own progenitor cells to repair cartilage over 12–24 months. ChondroFiller is the device name; Liquid Cartilage denotes the same scaffold combined with the patient's own mesenchymal cells in a single appointment.An injectable collagen scaffold sets into a gel at body temperature and recruits the body's own progenitor cells to repair cartilage over 12–24 months.

Knee cartilage repair versus stem cell therapyEstablished cartilage repair using autologous chondrocytes shows 10–17 year durability for focal knee defects; mesenchymal stem cell therapies have not been tested in large-scale trials against them.Established cartilage repair using autologous chondrocytes shows 10–17 year durability for focal knee defects; mesenchymal stem cell therapies have not been tested in large-scale trials against them.

ChondroFiller™ durability compared with ArthrosamidChondroFiller™ recruits the patient's own progenitor cells to build new cartilage tissue within a collagen scaffold. Three-year published follow-up shows mean IKDC scores of 80 — a 32.4-point improvement from baseline — with durability reported to extend beyond five years.ChondroFiller™ recruits the patient's own progenitor cells to build new cartilage tissue within a collagen scaffold.

Medial knee pain that isn't a meniscus tearAround 850,000 meniscal surgeries are performed annually in the United States, yet five other structures in the medial knee generate pain so similar that clinicians commonly mistake them for meniscal tears.Around 850,000 meniscal surgeries are performed annually in the United States, yet five other structures in the medial knee generate pain so similar that clinicians commonly mistake them for meniscal tears.

What separates ChondroFiller from Liquid CartilageChondroFiller is a single collagen scaffold delivered two ways: as an outpatient injection alone, or combined with patient-derived cells under the clinical brand Liquid Cartilage™. Naming overlap at clinics obscures which is being offered.ChondroFiller is a single collagen scaffold delivered two ways: as an outpatient injection alone, or combined with patient-derived cells under the clinical brand Liquid Cartilage™.

The cost of leaving a knee cartilage defect untreatedKnee cartilage defects do not heal because cartilage lacks blood supply; defects widen under load with each step, spreading damage to surrounding tissue and progressing towards osteoarthritis if untreated.Knee cartilage defects do not heal because cartilage lacks blood supply; defects widen under load with each step, spreading damage to surrounding tissue and progressing towards osteoarthritis if untreated.

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.

ChondroFiller combined with BMAC for cartilage repairA collagen scaffold traps bone-marrow stem cells in cartilage defects, preventing the clearance by synovial fluid that normally occurs within hours and enabling repair in a single outpatient appointment without surgery.A collagen scaffold traps bone-marrow stem cells in cartilage defects, preventing the clearance by synovial fluid that normally occurs within hours and enabling repair in a single outpatient appointment without surgery.

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.

STACi vs MACI for knee cartilage repairSTACi performs knee cartilage repair in one operation by combining bone-marrow stem cells with patient chondrocytes on a three-dimensional scaffold — differing from MACI in cell composition and scaffold structure, though lacking randomised-trial evidence for long-term durability.STACi performs knee cartilage repair in one operation by combining bone-marrow stem cells with patient chondrocytes on a three-dimensional scaffold — differing from MACI in cell composition and scaffold structure, though lacking randomised-trial evidence for long-term durability.
