摘要： A suture system including a suture construct having a first reduction construct configured to be selectively arranged in an expanded state and a reduced state. The first reduction construct includes a first locking limb, a first contractible loop, and a first opposed loop disposed generally opposite to the first contractible loop, wherein reduction of the first opposed loop contracts the first contractible loop from the expanded state into the reduced state and secures the suture construct in the reduced state. The suture construct may also include a second reduction construct. Optionally, the suture system includes a first and a second pusher tube defining a first and a second lumen, respectively, wherein each pusher tubes are advanced over portions of opposed loops, respectively, and wherein distal portions of opposed loops extend beyond the pusher tubes, respectively.

摘要： An implant system for a knee comprising a femur and a patella. The implant system includes a patella implant comprising an implant body. The implant body comprises a bone facing surface, an articular facing surface, and at least one dimple. The bone facing surface engages bone beneath an implant site formed in the patella. The articular facing surface faces towards an articulating surface of the femur and has a non-anatomical shape (such as a dome). The dimples are formed in the articular facing surface and have a load bearing surface to engage against the articulating surface of the femur. The load bearing surface may have a contour that substantially corresponds to a spherical portion of a generally spherical segment or has an elongated, partially oval shape, and may be configured to increase contact area with the articulating surface of the femur, reduce stress concentrations, and increase resistance to dislocation subluxation.
