Chondral and osteochondral knee repair
Treat knee cartilage lesions and osteochondral defects in a single-stage procedure, even in the presence of mild to moderate osteoarthritis (Kellgren-Lawrence 0-3),1,2 with the porous, biocompatible CARTIHEAL◊ AGILI-C◊ Cartilage Repair Implant; shown to be clinically superior to the current surgical standard of care in level 1 clinical data.*1,2
Repair cartilage, restore bone, relieve pain1-3
The need for knee cartilage repair is expected to grow,4 with articularcartilage injuries already observed in 60-66% of knee arthroscopies5-7and knee cartilage repair procedures projected to increase through2031.4 However, conventional approaches currently result in an average1 in 4 patients not returning to sport.**8 Furthermore, many patientstreated with microfracture return to the operating room.***9
As an alternative to conventional surgical repair methods, theCARTIHEAL Implant is a naturally occurring, biomaterial scaffold thathelps repair cartilage and restore bone;1-3,10-14 shown to result in asignificantly greater improvement in overall KOOS scores*1,2 andreduced the risk of total knee arthroplasty or osteotomy by 87%.****1
Designed for off-the-shelf convenience, the procedure can be carried outin a single stage without any additional preparation of the implant.

Suitable for use across a range of indications
The CARTIHEAL Implant can be used to support a broad range of chondral and osteochondral repair indications, ranging from skeletally mature patients to older patients.
Defect types and application
Key features
Backed by level 1 clinical data,1,2 the CARTIHEAL Implant offers surgeons numerous clinical and procedural advantages.
Step 1: Position and drill
Position and verify the aligner perpendicular to the articular surface. Attach the K-wire to a drill and thread through the aligner, and drill until the indicator line is reached. After releasing the K-wire, the aligner is removed. After attaching the drill bit to a drill, thread it into the positioned drill sleeve and over the K-wire until it reaches a stop.

After connecting the quick-connect handle, insert the reamer over the K-wire and manually rotate clockwise until the indicator line is no longer visible from all sides. With the K-wire still in place, remove the reamer and rinse with saline.
Connect the shaper to the quick-connect handle and insert the shaper over the K-wire. Manually rotate clockwise until the indicator line is no longer visible and rinse with saline to remove debris.
Step 3: Trim peripheral cartilage
Remove the K-wire, then use the cartilage cutter or a scalpel to trim the peripheral cartilage to provide smooth edges and avoid tissue entrapment during CARTIHEAL Implant insertion.
Step 4: Insert the CARTIHEAL Implant
Firmly insert the CARTIHEAL Implant using your thumb until the implant is flush with the articular cartilage. Using the tamper, gently push the implant into its final position 2mm below the surface of the articular cartilage. When using multiple implants, maintain a bone bridge of at least 5mm between implants to avoid impingement.
Please refer to the full surgical technique guide for full details and precautions.
CARTIHEAL Implant mechanism of action
After implantation, the CARTIHEAL Implant has a distinct, two-phase mode of action.
In the bone phase, mesenchymal stem cells (MSCs) adhere and differentiate into osteogenic cells, which form new bone (demonstrated in vitro).12
In the cartilage phase, a modified porosity helps MSCs differentiate into chondrocytes. On the surface, chondrocyte cells migrate from the surrounding native cartilage and form new cartilage (demonstrated in vitro and in vivo).10,14,16,17
