Borchers et all studied meniscus and cartilage injuries in primary ACL and revision surgeries through the Multicenter Orthopaedic Outcomes Network and the Multicenter ACL Revision Study. This research found that meniscus injuries are the most common additional injury found in both primary procedures and revision. Having history of meniscectomy is also the most important factor associated with cartilage damage. This indicates that in the presence of a meniscus injury the best course of treatment, if possible, to to repair the meniscus injury. Roman et all reviewed a different study of 437 ACL reconstructions with 82 meniscus repairs and found that the repair had a ninety-two per cent success rate at a two year follow up. So it appears that meniscus repairs are quite successful and that this is the best way to maintain the integrity of the structures in the knee which protect from future wear and tear.
