title: Clinical results of meniscus repair with the meniscus arrow: a 4- to 8-year follow-up study.
abstract: The short-term clinical results of meniscus repair with the meniscus arrow were promising. Unfavorable outcomes were reported in two studies, with longer follow-up, raising concerns about the efficacy of this device. We retrospectively reviewed 62 patients (mean age 23.7 years; range 14-37 years) that underwent all-inside meniscus repair, using the meniscus arrow. Seventeen patients had an isolated meniscus tear (ACL intact group) and 45 patients concomitant ACL rupture that was reconstructed at the same time with the meniscus repair (ACL reconstructed group). All patients followed a non-aggressive rehabilitation protocol. Follow-up was assessed by clinical examination, Lysholm and Tegner score, IKDC knee examination form and KT-2000 arthrometry for the anteroposterior laxity of the reconstructed knees. At an average follow-up of 73 months (range 49-96 months) there were three failures (4.8%), one from the ACL intact group and two from the ACL reconstructed group. One patient developed arthrofibrosis (ACL reconstructed group) that resolved conservatively. Soft tissue irritation at the repair site was noted in three patients. In two patients the symptoms were transient. In the third patient the arrow tip was cut off under local anaesthesia due to saphenous infrapatellar branch irritation and the symptoms resolved (inappropriate arrow size). KT-2000 arthrometry showed that sagittal knee laxity was less than 3 mm in all reconstructed knees. The mean Tegner activity score decreased from 6.7 (pretrauma) to 6.2 (postoperatively). The average Lysholm score was 96, with normal or nearly normal function of all success knees, according to the IKDC knee examination form. Our results show a high clinical success rate of meniscus repair with the meniscus arrow. We found this device both safe and effective.
