Abstract: A graft preparation instrument includes a first mold including first protrusions disposed on a first working surface of the first mold. The first protrusions are separated by first spaces. A second mold includes second protrusions disposed on a second working surface of the second mold. The second protrusions are separated by second spaces. The first and second molds are movable from an open position of the instrument to a closed position of the instrument. In the open position, the first and second working surfaces are separated by an open position distance large enough to place a graft therebetween. In the closed position, the first and second working surfaces are separated by a closed position distance such that the first protrusions are operable to form indentations in a first surface of the graft and the second protrusions are operable to form indentations in a second surface of the graft.

Abstract: A method of repairing an articular cartilage defect with the partial joint resurfacing implant includes surgically creating an opening in the articular cartilage defect site. The method also includes obtaining a partial resurfacing implant which is implanted into the opening. The partial resurfacing implant includes a top articulating portion, an implant fixation portion, and a locking mechanism. The implant fixation portion including an upper segment coupled to the top articulating portion and a bone interfacing segment configured to facilitate insertion into the articular cartilage defect site. The method further includes the bone interfacing segment being inserted into the opening with the top articulating portion and adjacent articular cartilage being positioned to each other to facilitate motion and load transfer over the defect site.

Abstract: Surgical instruments for use in mapping tissue defects include telescoping rulers and tubes. One of the instruments has a pointed anchoring tip for piercing tissue near the site of the defect. Another instrument has a hook for catching an anatomical landmark. Measuring portions of the rulers of both instruments include distance indicia so that a coordinate system can be established for mapping the location of the defect or of an implant at the defect site. The coordinate system can be re-established at a later time using the same fixation point for the anchoring tip and the same landmark for the hook to evaluate the clinical effects of the treatment selected. The method of using the instrument set is also described.

Abstract: An articular cartilage fixation device and method for repairing and regenerating diseased or injured soft tissue such as articular cartilage of the knee, hip, shoulder, and the like. A cartilage flap or cartilage repair device is retained within the chondral or osteochondral defect for a sufficient amount of time such that the cartilage repair device can perform its function and facilitate an appropriate healing response. A plurality of biocompatible anchors are attached to a plurality of flexible members and are shaped to seat into the tissue beneath or near the defect such that the cartilage flap is retained within the defect.
