A method for repairing a ligament or tendon, the method comprising: passing one or more sutures through and/or around each respective end of a completely or partially torn ligament or tendon; placing a generally cylindrical hollow body or ring over the respective ends of the completely or partially torn ligament or tendon; passing the one or more sutures through the generally cylindrical hollow body or ring; and tying the one or more sutures around or through the generally cylindrical hollow body or ring wherein the sutures are secured in place around or through the generally cylindrical hollow body or ring via one or more notches or holes defined by the generally cylindrical hollow body or ring. The method may further comprise tensioning the one or more sutures while tying them around or through the generally cylindrical hollow body or ring so that the respective ends of the completely or partially torn ligament or tendon are brought into and stay in contact with each other inside the generally cylindrical hollow body or ring after the tying is complete. The generally cylindrical hollow body or ring preferably is biodegradable and may be coated with an ECM.
