[TREATMENT OF SEVERE MEDIAL COLLATERAL LIGAMENT RUPTURE IN MULTI-LIGAMENT INJURY].Zhongguo Xiu Fu Chong Jian Wai Ke Za Zhi. 2016 Aug 08; 30(8):956-960.ZX
To compare the clinical efficacy between medial collateral ligament (MCL) repair and MCL reconstruction in multi-ligament injury.
Thirty-one patients with MCL rupture and multi-ligament injury of knee joint were treated between August 2008 and August 2012, and the clinical data were retrospectively analyzed. Of 31 patients, 11 cases underwent MCL repair (repair group), and 20 cases underwent MCL reconstruction (reconstruction group). There was no significant difference in gender, age, body mass, injury side, injury cause, and preoperative knee Lyshlom score, International Knee Documentation Committee (IKDC) subjective score, range of motion, and medial joint opening between 2 groups (P>0.05). The postoperative knee subjective function and stability were compared between 2 groups.
All incisions healed by first intention, and no postoperative complication occurred. All patients were followed up 2-4 years (mean, 3.2 years). At 2 years after operation, the IKDC subjective score, Lyshlom score, and range of motion were significantly increased in 2 groups when compared with preoperative ones (P<0.05). The range of motion of reconstruction group was significantly better than that of repair group (P<0.05). No significant difference was found in IKDC subjective score and Lyshlom score between 2 groups (P>0.05). The medial joint opening was significantly improved in 2 groups at 2 years after operation when compared with preoperative one (P<0.05), but no significant difference was found between 2 groups (P>0.05).
Both the MCL reconstruction and MCL repair can restore medial stability in multi-ligament injury, but MCL reconstruction is better than MCL repair in range of motion.
