FIELD: medicine.

SUBSTANCE: articular implant device for fixing a meniscus to a bone comprises a cylindrical retainer with a sharp distal end and a flat proximal portion. Retainer comprises an eyelet configured to pass a surgical suture through it. Retainer is provided with at least one longitudinally extending inner channel, having a size sufficient for transporting at least one of the blood and nutrients from the distal end to one or more holes located in the lateral surface of the retainer at the proximal end. A kit for use in procedures for treating meniscus horn ruptures, preventing meniscus horn ruptures or degenerative meniscus ruptures comprises said articular implant device and a delivery device provided with a handle at the proximal end, detachably connected to the articular implant device at the distal end. A method for restoring an injured or weakened soft tissue, wherein the soft tissue depends on the influx of blood and nutrients from a nearby bone, wherein the method comprises steps of, on which the above articular implant device is inserted into the weakened soft tissue and into the bone or into the hole drilled in the bone. Articular implant device comprises a set of tubes extending from a distal end to a proximal end, wherein the set of tubes is configured to collect blood and nutrients from the inside of the bone and transport them from the proximal end into the weakened soft tissue.
