Abstract: Methods and systems for cartilage restoration. A 3-dimensional anatomic map is obtained for a recipient joint tissue that includes a normal area and a diseased area. A 3-dimensional patient-specific graft model is developed that will restore the diseased area to its healthy form. A 3-dimensional anatomic map is obtained for a donor joint tissue and the recipient anatomic map and/or the graft model are compared to the donor anatomic map to determine the suitability of the associated donor joint tissue to restoring the recipient joint to its healthy form. The donor joint tissue is shaped to conform to the graft model, thereby forming a patient-specific graft.

Abstract: A system, a machine-readable storage medium storing instructions, and a computer-implemented method are directed to a Digest Engine that identifies a feature(s) that is predictive of relevance, to a target member account in a professional social network, of content from a member group(s) to which the target member account is subscribed. Based on the feature(s), the Digest Engine determines a portion(s) of relevant content created amongst respective member accounts subscribed to the member group(s). The Digest Engine generates a persistent message providing access to the portion(s) of relevant content. The Digest Engine sends the persistent message to the target member account.
