Abstract
A cementless individual patellofemoral resurfacing system including a femoral lamellar sheet having an articular surface and a bone covering surface, at least one rib attached to the femoral lamellar sheet along at least one long border thereof, a patella lamellar sheet having a patella articular surface and a patella covering surface non-breachingly attached to bone in a joint-sparing manner. The cementless patellofemoral resurfacing system can also serve as a central supporting component for at least one attachable and detachable condylar articular surface resurfacing elements. The system can be implemented mutatis mutandis in other bony joints in the body.

1-58. (canceled)
A cementless bony joint resurfacing system, comprising:
- at least a first lamellar sheet having an articular surface and a bone covering surface configured to engage an articular surface of a first bone;
- at least a second lamellar sheet having an articular surface and a bone covering surface configured to engage an articular surface of a second bone;
- and
- at least one attachment tab coupled to at least one of said lamellar sheets ;
- and
- wherein said system is a joint sparing system, such that when in place:
- a) said system is non-breachingly attached to said bones;
- and
- b) said at least one tab is attached to said bone at a joint sparing location.
A method for cementless joint resurfacing, comprising:
- providing cementless joint resurfacing components including:
- at least a first lamellar sheet having an articular surface and a bone covering surface configured to engage an articular surface of a first bone;
- at least a second lamellar sheet having an articular surface and a covering surface configured to engage an articular surface of a second bone;
- wherein at least one of said lamellar sheets comprises at least one attachment tab;
- and
- locating at least a portion of said at least one tab over at least one para-cartilage area of the bone;
- positioning the first lamellar sheet over an articular surface of a first bone;
- positioning the second lamellar sheet over an articular surface of a second bone;
- and
- attaching said at least a portion of said at least one tab at said at least one para-cartilage area of the bone, thereby non-breachingly attaching the resurfacing components to a bone and/or cartilage in a joint-sparing manner.
A kit, comprising:
- at least one cementless bony joint resurfacing system, comprising:
- at least a first lamellar sheet having an articular surface and a bone covering surface configured to engage an articular surface of a first bone;
- at least a second lamellar sheet having an articular surface and a covering surface configured to engage an articular surface of a second bone;
- and
- a plurality of universal implant to bone fixation system anchors configured to attach said first and second lamellar sheets to said joint bones, such that when in place,
- a) said universal implant to bone fixation system anchors are attached to said bone at a joint sparing location;
- and
- b) said system is non-breachingly attached to said bones.
