Knee Cartilage Repair and PreservationArticular cartilage lacks blood vessels, so when damaged it forms fibrocartilage—a mechanically inferior scar tissue that typically deteriorates within two to three years. This biological constraint shapes every treatment option, from temporary symptom relief to procedures attempting true cartilage regeneration.Articular cartilage lacks blood vessels, so when damaged it forms fibrocartilage—a mechanically inferior scar tissue that typically deteriorates within two to three years.

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.

Knee cartilage damage left untreated and when repair helpsCartilage lacks blood vessels, nerve fibres, and lymph channels, so repair cells cannot reach injuries and pain does not warn of damage, allowing lesions to expand silently until they become clinically serious.Cartilage lacks blood vessels, nerve fibres, and lymph channels, so repair cells cannot reach injuries and pain does not warn of damage, allowing lesions to expand silently until they become clinically serious.

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.

Meniscus tear: which specialist to see and whether surgery is neededThe meniscus's blood supply determines whether a tear can heal: the outer third can regenerate, the inner zone cannot. For degenerative tears, surgery does not improve outcomes and increases osteoarthritis progression; conservative physiotherapy leads to recovery within four to eight weeks.The meniscus's blood supply determines whether a tear can heal: the outer third can regenerate, the inner zone cannot.

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.

Telling a meniscus tear from knee arthritisA meniscus tear begins at an identifiable moment. Osteoarthritis doesn't—it accumulates silently over months or years. This difference in onset is the single most reliable way to tell them apart.A meniscus tear begins at an identifiable moment. Osteoarthritis doesn't—it accumulates silently over months or 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.

Getting a knee bursitis diagnosisKnee bursitis presents as a tender, fluid-filled lump; its location—over the kneecap, below it, or on the inner knee—identifies which bursa is inflamed and thereby the cause: chronic kneeling, mechanical stress, or direct injury.Knee bursitis presents as a tender, fluid-filled lump; its location—over the kneecap, below it, or on the inner knee—identifies which bursa is inflamed and thereby the cause: chronic kneeling, mechanical stress, or direct injury.
