Implementations may include one or more of the following features. The system in which the transosseous coupler applies tension on the implant, where the tension holds the joint-facing articular surface in place on a distal end of the bone. A first diameter of the joint-facing articular surface is smaller than a second diameter of the natural articular surface of the bone. A first diameter of the joint-facing articular surface is greater than a width of an osteochondral lesion (OCL) of the natural articular surface and smaller than a second diameter of the natural articular surface of the bone. The system may include an implant that may include a body having a joint-facing articular surface, a convex posterior surface, and an edge between the joint-facing articular surface and the convex posterior surface. The bone tunnel may include a distal end and a proximal end and the proximal end exits between a distal end of the bone and a proximal end of the bone; and the distal end of the bone tunnel exits within a bone pocket that extends proximally from the natural articular surface into the bone. The implant may be coupled to the bone anchor by a transosseous coupler. A body of the implant may seat within the bone pocket with the edge extending above the natural articular surface of the bone. The joint-facing articular surface may be convex and a top of the joint-facing articular surface may be congruent with cartilage around the implant. The joint-facing articular surface may be convex with the edge being circular. The convex posterior surface may have an implant radius greater than a bone radius of the bone pocket. The transosseous coupler may include a tether configured to engage with a first connector coupled to the implant and configured to engage with a second connector coupled to the bone anchor.
