Clinical effects of arthroscopic reconstruction of anterior cruciate ligament and minimally invasive reconstruction of posteromedial corner / 中国骨伤

ABSTRACT

<p><b>OBJECTIVE</b>To evaluate the clinical effects of arthroscopic reconstruction of anterior cruciate ligament (ACL) and minimally invasive reconstruction of posteromedial corner (PMC).</p><p><b>METHODS</b>There were 22 cases of ACL and PMC tear were performed with reconstruction from March 2012 to February 2014. The patients were 29.4 years old on average, including 8 males and 14 females. ACL reconstruction was performed under arthroscopy and PMC reconstruction was performed minimally invasively through the ACL incision. The stability of knee was assessed by anterior drawer test,Lachman test,vulgus stress test and Slocum test. The function of knee was assessed by Lysholm score and Tegner activity rating. MRI of knee was checked 12 months after operation.</p><p><b>RESULTS</b>The stability tests of all patients were negative at 2 and 6 months after operation, and there was one positive case in anterior drawer test and another positive case in vulgus stress test at 12 months after operation. Lysholm score of all patients 12 months after operation was 96.8 +/- 6.8, which was significantly better than 32.0 +/- 11.2 before operation. Tegner activity rating of all patients at 12 months postoperatively was 6.1 +/- 0.9, which was significantly better than 0.9 +/- 0.5 before operation. It showed the grafts were very well in the MRI 12 months postoperatively.</p><p><b>CONCLUSION</b>Arthroscopic ACL reconstruction and minimally invasive PMC reconstruction can restore the stability of knee.</p>
