Don't let knee pain define your life
Cartilage defects generally do not heal on their own. RECARTA is an autologous chondrocyte therapy that uses the patient’s own cartilage cells.
RECARTA is an autologous chondrocyte therapy manufactured by KELI Therapeutics in a licensed GMP facility in Kaunas, Lithuania. The treatment is performed in two surgical stages: cartilage biopsy, then cell culture and manufacture, followed by implantation.

RECARTA | Autologous Chondrocyte Therapy

Cartilage damage doesn't heal on its own
Articular cartilage is the smooth, protective tissue covering the ends of bones in your joints. Unlike other tissues in your body, cartilage has no blood supply and very limited ability to repair itself.
When cartilage is damaged — whether from injury, sports, or wear — the defect tends to worsen over time, leading to pain, swelling, and reduced mobility. Without proper treatment, this can progress to osteoarthritis.
Your own cells, regenerating your cartilage
RECARTA is autologous chondrocyte therapy (ACT). It uses your own cartilage cells, cultivated and implanted to regenerate healthy tissue.

RECARTA uses the patient’s own cartilage cells.
Licensed GMP manufacture
KELI Therapeutics manufactures RECARTA in a licensed GMP facility in Kaunas, Lithuania.
Individual treatment planning
Suitability, surgery, and rehabilitation are planned with the treating orthopaedic surgeon.
Published clinical research
The evidence base draws on published research in autologous chondrocyte implantation, including matrix-associated techniques.

Meet the chondrocytes
What you see in this image are chondrocytes — the specialized cells responsible for producing and maintaining cartilage tissue. These are the very cells that RECARTA uses to regenerate your damaged knee cartilage.
In RECARTA process, a small sample of your own chondrocytes is harvested during a minimally invasive biopsy. They are then carefully multiplied in our licensed facility over approximately four weeks, producing millions of healthy, patient-specific cells.
Once cultivated, these cells are applied to a biocompatible membrane and implanted into the cartilage defect — where they integrate with surrounding tissue and produce new, hyaline-like cartilage that closely resembles the original.
The RECARTA treatment process
The treatment involves two surgical stages, with a controlled laboratory manufacturing phase in between.
Stage 1: Cartilage biopsy
The surgeon collects a small cartilage biopsy to prepare the individual treatment.
First surgical procedureLaboratory phase: cell culture and manufacture
The cartilage cells are isolated from the biopsy sample and cultured under controlled conditions in KELI Therapeutics’ licensed GMP facility in Kaunas, Lithuania.
Licensed GMP facilityStage 2: Implantation
The prepared RECARTA product is implanted into the cartilage defect.
Second surgical procedureRehabilitation
The rehabilitation plan is agreed individually with the treating specialist.

View all FAQsWho is a good candidate for RECARTA?
RECARTA may be considered for people with focal knee cartilage defects. A qualified orthopaedic specialist must assess the cartilage lesion, knee stability, alignment, other joint changes, and rehabilitation plan before determining suitability.
How long does recovery take?
The rehabilitation plan and timing of return to activities are agreed individually with the treating specialist.
Is RECARTA covered by insurance?
Coverage and insurance options depend on the country and insurer.
How effective is the treatment?
Published research on autologous chondrocyte implantation, including matrix-associated techniques, reports clinical and imaging outcomes in selected patient groups. Individual results vary, and an orthopaedic specialist can explain how the evidence relates to your condition.

Why Knee Cartilage Doesn’t Heal on Its Own
Cartilage lacks blood vessels and nerves, which is why it cannot self-repair like other tissues in the body.
