Repaired or replaced
Torn ligaments that lead to surgery are either repaired, replaced, or augmented (repaired and supplemented with other tissue).
Tissues commonly used for other than a repair include locally harvested tissue referred to as an autograft (a hamstring or central third of a patellar tendon). Allograft
tissues (donated cadaveric tissue) are more numerous with regards to tissue options. Discuss w/ your md.
