ABSTRACT:
A method of assembling an improved bio-absorbable cartilage repair system includes the step of directly inserting the insert into a cavity in the delivery unit so as to leave a top of the insert exposed. A flexible, porous fabric piece, consisting substantially of bio-absorbable material, is then applied over the exposed top of the inserted insert and through a plurality of the windows of the delivery unit sidewall. The fabric piece includes a central body portion configured and dimensioned to substantially cover the exposed top of the inserted insert, and a plurality of leg portions extending outwardly from the body portion, the leg portions being configured and dimensioned to fit through the windows. Substantially all of each leg portion is next pulled through a respective window to cause the body portion to deform the inserted insert into assuming the shape of the cavity therebelow. Finally, the leg portions projecting from the windows are trimmed. The remaining fabric piece retains the inserted insert within the delivery unit. Preferably, the pulling also causes the body portion to deform the exposed top of the inserted insert into assuming a desired shape or contour.
