The invention discloses an integrated artificial bone ligament bone graft and a preparation method thereof. The integrated artificial bone ligament bone graft comprises a first traction fiber part, a first bone tunnel weaving part, a central joint cavity part, a second bone tunnel weaving part and a second traction fiber part which are sequentially connected. The outer surface of the first bone tunnel weaving part and the outer surface of the second bone tunnel weaving part are sleeved with a first artificial bone and a second artificial bone respectively. Relevant complications generated by applying an autogenous or allogeneic bone patellar tendon bone graft can be avoided. Meanwhile, the bone graft and an autogenous bone can achieve bone-bone interface healing, compared with an existing artificial ligament product, an artificial bone ligament bone has enough strength and rigidity, and meanwhile healing of the graft and a bone tunnel is accelerated and is more reliable through artificial bone blocks at the two ends of the graft. Thus, healing of the graft and the bone after an operation can be obviously improved, therefore, the mid-long-term operation effect is improved, early postoperative rehabilitation is achieved, and a patient is helped to return to do exercise as soon as possible.
