Different clinical therapeutic choices for injuries of the medial collateral ligament Ⅲ grade and anterior cruciate ligament / 中国医师进修杂志

ABSTRACT

Objective To compare the clinical efficacy of different treatments for injuries of medial collateral ligament (MCL) Ⅲgrade and anterior cruciate ligament (ACL). Methods Forty-six patients with MCLⅢgrade and ACL injuries admitted to Dalian Central Hospital from June 2013 to April 2017 were retrospectively analyzed, including 28 males and 18 females. Sixteen patients underwent arthroscopic reconstruction of the ACL, and medial collateral ligament was repaired with two anchors simultaneously in 2 weeks (group A); 15 patients were treated with reconstruction of the ACL in 2 weeks, and 4 times extracorporeal shock wave therapies were performed 2 weeks after surgery (group B); 15 patients were treated with reconstruction of the ACL in 2 weeks, and fixed with external fixation (group C). Patients were assessed in 3 months, 6 months and 12 months after surgery, and the Lysholm knee function score, the international knee documentation committee knee evaluation form (IKDC) score and the knee joint range of motion (ROM) were recorded. Results Three months after operation, the levels of Lysholm scores, IKDC scores and ROM in three groups were significantly improved compared with those before operation (P < 0.05). The IKDC scores and Lysholm scores in both group A and group B [IKDC score (51.8 ± 3.1), (49.7 ± 3.9) scores; Lysholm score (70.3 ± 3.7), (69.5 ± 3.4) scores] were better than those in group C [(44.5 ± 3.4), (59.3 ± 4.7) scores], and there were significant differences (P<0.05). Six months and 12 months after operation, the IKDC score, Lysholm score and the knee joint ROM in group A were better than those in group B and group C (P<0.05). Conclusions For knee joint MCLⅢgrade combined with ACL injuries, surgical treatment will obtain better functional scores and activity, and the effect of conservative treatment of MCL injury with extracorporeal shock wave therapy is not good.
