The study is scheduled for presentation July 9 at the annual meeting of the American Orthopaedic Society for Sports Medicine (AOSSM) in Keystone, CO.
The so-called Trufit plug is designed to have mechanical properties that are similar to adjacent cartilage and bone. The top layer has properties similar to cartilage, whereas the lower layer has properties similar to bone.
The study found that the plug demonstrated a predictable process of maturation on imaging studies that paralleled the biology of their incorporation. With increasing postoperative duration, the repair tissue demonstrated encouraging properties with T2 values that resembled native articular cartilage, they said.
Quantitative MRI, when combined with morphologic assessment, helped researchers understand the natural history of the repair techniques and define those patients who are most likely to benefit from the surgery.
