Publicação de artigo: “ Treatment and outcomes of lateral collateral ligament injury associated with anterior and posterior cruciate ligament injury at 2-year follow-up.


Injuries to the lateral collateral ligament (LCL) are most commonly associated with anterior cruciate ligament (ACL) injury than with posterior cruciate ligament (PCL) injury. There is currently a paucity in the literature in regards to treatment and outcomes of such lesions.


30 patients underwent surgical treatment of concomitant LCL and ACL injury or concomitant LCL and PCL injury with follow-up postoperative period of two years. The Lysholm score and varus stress radiographs was calculated and analysed before and at 6, 12, and 24 months postoperatively.


There was a significant increase in scores between two timepoints over the follow-up period for both groups: before surgery and after 6 months, and between 6 and 12 months (p < 0.05). The lateral joint opening measured on the varus stress radiographs was greater in group 2 than in group 1 before surgery (p = 0.04). When assessing each group separately, the lateral joint opening decreased at each timepoint in the first year for both groups (p < 0.05).


Patients diagnosed with combined LCL and PCL injuries were shown to have a higher degree of lateral opening at the time of injury when compared to patients with combined LCL and ACL injuries. However, there was no difference in lateral joint opening on stress radiography after 12 months postoperatively in either group. Finally Lysholm scores for both groups significantly increased between the preoperative period and 6 months postoperatively, as well as between 6 months and 12 months postoperatively.
