Background: The treatment of anterior cruciate ligament (ACL) rupture complicated with posterior lateral meniscus root (PLMR) tears remains controversial. The goal of this study was to evaluate clinical outcomes of PLMR tear refixation versus left untreated at the time of reconstruction.

Material and Methods: From August 2001 to January 2012, 31 patients who undergone repair of PLMR tears were evaluated and compared with a matched control group with untreated PLMR tears. Clinical evaluation consisted of the Lysholm scale, subjective International Knee Documentation Committee (IKDC) questionnaires, and radiographic evaluation with MRI.
Results: Regarding to the Lysholm score and the subjective questionnaire score, there were no statistical difference between the 2 groups. However, patients after operative treatment reach higher functional scores and lower rates of osteoarthritis (normal: group A, 80%, and group B, 48%, respectively) with statistical significance (P<0.05) compared to the matched control group.
Conclusions: Surgical and conservative treatment of the PLMR can both effectively improve knee function. However, a tendency towards higher functional scores and lower rates of osteoarthritis for patients with operative treatment was observed.
