SYSTEM AND METHOD FOR REPAIRING TENDONS AND LIGAMENTS
An implant and method for the repair of a tendon or a ligament along at least one load direction. The implant includes at least one first anchor portion and at least one tension member oriented along a load direction. The first anchor portion preferably has a larger surface area of engagement with the tendon or ligament to spread loads across more tissue. The tension member is preferably secured to the first anchor portion with an overlapping attachment. Tension on the tension member is preferably adjustable by the surgeon.
Systems, apparatuses and methods for securing tissue to bone using a bone anchoring system are described. Methods and apparatuses may allow transformation between locked and unlocked states, thereby allowing adjustment of the tension in the suture. The apparatus and/or methods may allow unidirectional movement of a suture, while preventing slippage or movement of the suture and tissue in the opposite direction. Ends of a suture may be individually tensioned to adjust positioning of a tissue with respect to a bone.
