In addition, it is reinforced with a titanium-reinforced thread in the sense of an inner splint. This restores bone contact and strengthens the ligament structure. The special advantages are obvious. The blood supply to the cruciate ligament is guaranteed again and healing can take place. The special anatomy of the cruciate ligament is preserved and thus also its unique biomechanics. The proprioceptive abilities of the cruciate ligament are also preserved. No tendon has to be removed and transplanted. This means that the post-treatment period is significantly reduced, no tendon removal is necessary and the patient only has to undergo arthroscopic surgery.
