Abstract: In accordance with one or more embodiments herein, a patellofemoral implant arrangement 200 for repairing damage in a patellofemoral articulation of a patient is provided. The patellofemoral implant arrangement 200 comprises a femoral trochlear implant 250, comprising an articulating surface 255, and a patellar implant 300, configured to be inserted, preferably with press-fit, into a recess 620 in a patella 600 in such a way that the perimeter of an articulating surface 310 of the patellar implant 300 does not extend beyond a surrounding articulating surface of the patella 600. The articulating surfaces 255, 310 of the femoral trochlear implant 250 and the patellar implant 300 are designed to allow that they at least partly interact with each other when the implants 250, 300 are implanted into the knee joint and the patella 600 lies in the intercondylar groove of the femur.

Abstract: Embodiments of the present disclosure relate to design methods for designing a mandrel for hammering, pressing and/or pushing an implant into position in a recess made in a joint and firmly attach the implant to the bone of a patient, the mandrel comprising a contacting surface adapted to be in contact with an articulate surface of the implant to be inserted, the method comprising designing the contacting surface of the mandrel to fit the articulate surface of the implant in that the contacting surface of the mandrel has a cross-sectional profile corresponding to the cross-sectional profile of the implant.

Abstract: A crib apparatus comprises a headboard and a footboard, the headboard and footboard being spaced from and arranged substantially parallel to one another, and first and second side rails. The first and second side rails are spaced from and arranged substantially parallel to one another and substantially orthogonal to the headboard and the footboard. Each of the first and second side rails is operatively attached to the headboard and footboard. The crib apparatus further includes a mattress frame for supporting a mattress, the mattress frame being operatively attached to at least the headboard and footboard and being substantially orthogonal to the headboard, footboard and side rails. At least one of the headboard and the footboard includes an access opening therein through which the mattress can be slidably removed from the crib apparatus.
