A bio-absorbable cartilage repair system for regenerating damaged or destroyed articular cartilage on the surface of a bone by establishing a chondrogenic growth-supporting matrix between an area of removed damaged or destroyed articular cartilage and the adjacent healthy cancellous bone. The system is at least one assembly of a bio-absorbable delivery unit, configured and dimensioned to be mounted in both the removed area and the adjacent healthy area, and a porous bio-absorbable insert supported by and in the delivery unit and establishing communication between the removed area and the adjacent healthy area for a chondrogenic growth-supporting matrix. The insert preferably includes a repair factor (e.g., a growth factor, an attachment factor, or both) releasably disposed in the insert to assist in establishing the chondrogenic growth-supporting matrix.
A bio-absorbable cartilage repair system for regenerating damaged or destroyed articular cartilage on a joint surface of a bone by establishing a chondrogenic growth-supporting matrix between an area of damaged or destroyed articular cartilage that has been removed and an adjacent healthy area of articular cartilage and subchondral cancellous bone, said system comprising an assembly of:
A bio-absorbable cartilage repair system for regenerating damaged or destroyed articular cartilage on a joint surface of a bone by establishing a chondrogenic growth-supporting matrix between an area of damaged or destroyed articular cartilage that has been removed and an adjacent healthy area of articular cartilage and subchondral cancellous bone, said system comprising an assembly of:
A cartilage repair system adapted to be mounted on a joint surface of a bone to establish a chondrogenic growth-supporting matrix, comprising a delivery unit consisting substantially of completely bio-absorbable material which is dimensionally stable against substantial expansion by absorption of synovial joint fluid and configured and dimensioned to be mounted on and within the bone, said unit including a support frame and means for mounting said unit on and within the bone, and a porous insert consisting substantially of completely bio-absorbable material, defining at least 95% voids by volume, and supported by said support frame to provide a chondrogenic growth-supporting matrix.
A bio-absorbable cartilage repair system for regenerating damaged or destroyed articular cartilage on a surface of a bone by establishing a chondrogenic growth-supporting matrix between an area of damaged or destroyed articular cartilage that has been removed and an adjacent healthy area of articular cartilage and cancellous bone, said system comprising an assembly of:
A bio-absorbable cartilage repair system for regenerating damaged or destroyed articular cartilage on a joint surface of a bone by establishing a chondrogenic growth-supporting matrix between an area of damaged or destroyed articular cartilage that has been removed and an adjacent healthy area of articular cartilage and subchondral cancellous bone, said system comprising an assembly of:
A cartilage repair system adapted to be mounted on a joint surface of a bone to establish a chondrogenic growth-supporting matrix, comprising a delivery unit consisting substantially of completely bio-absorbable material and configured and dimensioned to be mounted on and within the bone, said delivery unit including a support frame and means for mounting said delivery unit on and within the bone, said delivery unit including means for retaining itself in the bone without either an expansion of the dimensions thereof or a relative rotation thereof, and a porous insert consisting substantially of completely bio-absorbable material and supported by said support frame to provide a chondrogenic growth-supporting matrix.
