Reinjuries in Repaired Meniscus. Three Cases Report.

we examined the causes of reinjuries in repaired meniscus of three cases more than one year after repairing. Case 1 was a 60-year-old male who had a medial meniscus peripheral tear and PCL injury. 21 months after repairing we underwent a partial meniscectomy. The removed meniscus had a degenerative change and we concluded that the reinjury causes were from the PCL injury and degeneration in the meniscus. Case 2 was 20-year-old male with an initial medial meniscal injury from playing baseball. Partial meniscectomy was done 17 months after the initial operation. The torn region was covered by an avascular tissue like a synovial membrane, and so we conculuded that the cause was from incomplete healing of the repaired meniscus. Case 3, a 16-year-old was reinjured 15 months after ACL reconstruction and a medial meniscus suture. The removed meniscus did not have a degenerative change. We conculuded that the meniscal tear of case 3 was a traumatic injury with no relation to the initial repair.
