Clinical evaluation of meniscus repair with a bioabsorbable arrow: a 2- to 3-year follow-up study.
In a clinical study with the bioabsorbable Bionx Meniscus Arrow we prospectively evaluated 113 consecutive patients (113 menisci) after all-inside meniscus repair. Repairs were performed in either the medial (80.5%) or lateral (19.5%) posterior horn in the red-red or red-white meniscal zone; 66% of patients underwent concomitant ACL reconstruction. Assessment was based on history, clinical examination, and Lysholm [37] and Cincinnati Knee Scores. After a mean follow-up was 33 months (range 24-43; n=105) 21 (20%) patients showed signs and symptoms consistent with a meniscus tear (16 medial, 5 lateral) and underwent partial meniscectomy. In 11 (52%) of the revised patients concomitant ACL reconstruction was performed; 4 (19%) of revised patients were older than 35 years. In the nonrevised the average Lysholm Score was 92.5 and the average Cincinnati Score 90.4. Two patients showed a distinct femoral cartilage damage. Patient's age did not significantly affect the revision rate. Meniscus repair with the bioabsorbable arrow leads to clinical results comparable to those of traditional suture techniques. When stabilized, patients with concomitant ACL reconstruction showed comparable results to patients without ACL rupture. The simple and time saving all-inside insertion obviates the need for additional incisions and avoids knot tying. A proper tear selection and arrow positioning is necessary and should avoid cartilage damage.
