MosaicPlasty: A Breakthrough Technique in Autogenous Osteochondral Grafting (AOCG)
MosaicPlasty is the result of more than a decade of animal and clinical experience, and refinements in surgical technique and instrumentation. In clinical use since 1992, MosaicPlasty has been shown to be an efficacious. reproducible and cost-effective means of restoring chondral defects. MosaicPlasty is indicated for the treatment of focal, full thickness, cartilage lesions of up to 9 cm2 in the knee and ankle. (Figure 1a).

The MosaicPlasty Procedure:
In a MosaicPlasty, small, cylindrical, autologous osteochondral grafts are taken from non-weight bearing areas of the femoral periphery at the patellofemoral joint. The graft are inserted into holes drilled at the site of the chondral defect, filling it with 60-80% transplanted hyaline cartilage (Figure 1b).
The specially developed MosaicPlasty technique ensures protection of the hyaline cartilage throughout the procedure. Fibrocartilage "grouting", growing upward from the prepared, cancellous bed, seals the interface between the grafts and the use of smaller, rather than larger, grafts in this procedure creates a smoother condylar contour (Figure 1c)
Long-term Animal and clinical studies
MosaicPlasty animal and clinical studies have been completed using grafts of 4.5mm or less in diameter and of 15mm (for cartilage defects) in length.
Hangody et al performed a MosaicPlasty in 152 patients with defects ranging in size from 1.0 to 8.5 cm2:
|
|
57 of 60 patients who were operated on three to five years ago were available for follow-up |
|
|
62% had condylar cartilage defects; 26% had an osteochondral defect; 12% had condromalasia patellae. |
|
|
An average of eight grafts were used to create the MosaicPlasty. |
|
|
Average non-weight bearing time was six to eight weeks. |
|
|
Average modified HSS score value was 90.7 |
