Reamer instruments and related methods are disclosed for use in preparing bone, such as a glenoid bone surface, to receive an implant requiring one of two or more possible surface geometries. Described reamer instruments can have a modular or multi-component design. A minimal number of components can be particular to a particular required geometry, which can allow assembly and use of reamer instruments of the present disclosure to be flexible, intuitive, and efficient. In some embodiments, a disposable reamer head assembly can be driven by a disposable drive tip through a pin-on-pin connection. The remaining components of the reamer instrument can be sterilized and re-used. To prepare bone for a half-wedge implant, a half-wedge housing can be coupled to a reamer instrument handle and a depth stop can be coupled to the housing to achieve the required geometry. Alternatively, a full-wedge housing can be coupled to the instrument handle.

Devices, systems, and methods are provided for ligament repair procedures, and can be used to establish a location and trajectory for forming a bone tunnel in bone. One exemplary embodiment of a surgical guide for using in a ligament repair procedure includes a guide arm and a carriage that can be selectively locked along the guide arm to define an angle of the bone tunnel. The guide arm also defines a location of a distal end of the bone tunnel. In some embodiments the carriage is configured to have a bullet side-loaded into it, and the bullet can be used to define a location of a proximal end of the bone tunnel. The present disclosure also provides for a gage that limits the distance a drill pin that drills the bone tunnel can travel. A variety of other, devices, systems, and methods are also provided.

A method of treating an articular surface of a metal orthopedic implant includes polishing the surface, blasting the surface with a blast media after the first polishing step and polishing the blasted surface of the metal orthopedic implant after the blasting step. The blasting step roughens the surface to create a surface skew R/Sdefined by peaks and valleys. The second polishing step reduces the surface skew to a negative skew R/Sand produces an average roughness R/Sthat is acceptable. Lubrication at the interface of the treated articular surface and the corresponding bearing articular surface is improved, thereby improving wear resistance. Both polishing steps may be performed by drag finishing the surface through an abrasive media.
