1. A tendon repair implant for repair of a tendon, the tendon repair implant comprising:
an elongated sheet-like structure formed of a polylactic acid and a collagen material, the sheet-like structure having a first compact configuration for delivery from an arthroscopic instrument and a second planar configuration having a longitudinal dimension, a lateral dimension, and a thickness dimension and configured to be affixed to a surface of the tendon such that the longitudinal dimension of the sheet-like structure extends parallel to a load bearing direction of the tendon;
wherein the elongated sheet-like structure includes a plurality of longitudinal pathways extending along the longitudinal dimension of the elongated sheet-like structure in the thickness dimension for at least some tissue in-growth oriented in a longitudinal direction, the longitudinal pathways having a cross-section width of 150 microns to 200 microns; and
wherein the sheet-like structure is configured to have an initial load share representing between 1% to 50% of an anatomical load applied to the tendon and the sheet-like structure at the time that the sheet-like structure is affixed to the tendon.
