[The treatment of meniscal tear with bio-absorbable arrow--3 years follow-up]

The introduction of bio-absorbable materials has improved the ability to offer a simple fast and friendly solution to meniscal tears. The technique of meniscal suture with bio-absorbable arrows is associated with lower morbidity and complication rates.

The clinical evaluation of treatment of meniscal tear by suture with bio-absorbable arrows.

During the period 1997-2004, 14 patients underwent arthroscopic all-inside meniscus repair. The "Biofix" bio-absorbable arrows fixation technique was used. Fourteen patients were followed--11 males and 3 females. Their mean age was 23 years (range 16-34 years). Follow-up period was an average of 34 months (range 6-72 months). Sport injuries were the main cause of meniscal tear (60%). Other causes included: work accidents (20%) and military accidents (20%). All the tears were located in an area suitable for suture in the "red-red" or "red-white" zone.

One patient had a tear of the lateral meniscus. Four patients had anterior cruciate ligament (ACL) tear. The mean length of the tear was 9.6 mm. Tears were fixed with 2.5 arrows in average. The clinical evaluation was by the Lysholm Score. Excellent results were reported in 10 patients, good in one patient, fair in 2 patients and poor in 1 patient. One patient suffered from a transient tender point on the medial joint line due to protruded arrow tip, one patient needed a menisectomy due to unresolved symptoms and one patient underwent ACL reconstruction.

Meniscal suture with bio-absorbable arrows is an easy and reliable suture technique compared to the classical methods and it seems to have a lower complication rate. Further studies are needed to establish the quality of the repair and the associated morbidity.
