[Clinical outcome of arthroscopic anterior cruciate ligament remnant-preserving reconstruction].

OBJECTIVE: To evaluate the clinical outcome of arthroscopic anterior cruciate ligament(ACL)reconstruction with remnant cuff preservation.

METHODS: There were 42 cases of ACL tear were performed reconstruction in our department from January 2012 to December 2014. The patients were 28.4 years old on average, 17 males and 25 females. ACL reconstruction was performed under arthroscopy with remnant cuff preservation. The stability of knee was assessed by Lachman test and anterior drawer test. The function of knee was assessed through Lysholm score and Tegner activity rating. MRI of the knee was checked 12 months postoperatively.

RESULTS: The stability tests of all patients were negative postoperatively. Lysholm score of all patients 12 months after operation was 96.8±6.1, which was significantly better than 37.8±7.1 of preoperatively. Tegner activity rating of all patients 12 months after operation was 6.2±0.9, which was significantly better than 2.1±0.4 of preoperatively. It showed the grafts were very well in MRI 12 months after operation.

CONCLUSIONS: Arthroscopic anterior cruciate ligament remnant-preserving reconstruction could restore the stability of knee.
