Balanced: The acl is sacrificed. If the PCL is torn a posterior stabilized prosthesis is used. The mcl & lcl are balanced.

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.
