Novel joint implants, delivery systems, and associated insertion techniques are presented. These may be used to cure meniscal root tears, prevent meniscal root tears or degenerative meniscal tears and the like, and prevent the progression or onset of osteoarthritis of the joint and rejuvenate the joint. The implants can also be used to repair and cure rotator cuff tears, labral tears and any tears of soft tissue that require the blood from bone (to which it is fixed) for healing. A minimally invasive technique for (i) repairing the meniscal root that recreates the natural anatomy without requiring violating trans tibial drill holes, as well as (ii) providing for recirculation of blood flow and nutritional healing elements into the meniscal root, using associated novel implant devices, are thus also described. Exemplary implants comprise an anchor and a washer, or an integrated tack device, or a suture anchor, that protrude into bone underneath a meniscal root attachment site. The implants contain microtubes that allow for blood and nutrients to flow from the bone interior into the meniscal root and meniscus. Thus, the implant functions as an "irrigation system" for the meniscus, which effectively revascularizes it, thereby allowing it to repair itself. As such, the novel implant and technique can slow down or even stop the progression of osteoarthritis by rejuvenation of the meniscal root and, subsequently, the meniscus itself. This allows for maintaining the dissipation of hoop stresses and, as a result, protection of the articular cartilage.
