Healing potential of meniscal tears without repair in knees with anterior cruciate ligament reconstruction.
BACKGROUND
Few previous studies have documented the healing potential of meniscal tears that are left to heal without repair.


OBJECTIVE
To determine the healing rates of meniscal tears left without repair in knees with anterior cruciate ligament reconstruction.


METHODS
Prospective cohort study.


METHODS
One hundred and ninety-two knees were evaluated at the time of anterior cruciate ligament reconstruction and repeat arthroscopy. The healing rates of 41 medial and 42 lateral torn menisci without repair were evaluated by the same 2 surgeons in an identical fashion.


RESULTS
Of 41 medial torn menisci left without repair, 22 (56%) were considered completely healed, 3 (7%) were incompletely healed, 11 (24%) were unhealed, and 5 (10%) had expanded unhealed lesions. Of 42 lateral torn menisci, 31 (74%) were considered completely healed, 2 (5%) were incompletely healed, 6 (14%) were unhealed, and 3 (7%) had expanded unhealed lesions. The healing rate of a medial meniscal tear was length dependent and not related to reconstructed ligament stability.


CONCLUSIONS
Stable meniscal tears at the time of anterior cruciate ligament reconstruction possibly could be left in situ. However, longer medial meniscal tears are thought to require additional stabilizing procedures.
