Arthroscopic Anterior Cruciate Ligament Reconstruction Using and Autogenous Composite Graft with Bioabsorbable Implant Fixation

In this prospective study, we used a composite graft (bone-hamstring tendon-bone enrolled with fibrin clot) and adopted a biologic fixation aided by a single-incision arthroscopic technique for patients with a deficient anterior cruciate ligament (ACL). The study included 20 patients (15 men and 5 women) with a mean age of 23.7 years (range, 18 to 27 years) at the time of surgery The graft was fixed by a alternate surgical technique (in the femur, with bioabsorbable pins; in the tibia, using bioabsorbable interference screws with centering interpositional fixation). All cases were follow-up at least 18 months (average: 25.6). All cases showed a firm endpoint in Lachman's test. We used the Lysholm score system and Tegner scale for postoperative evaluation. The results of Lysholm score showed were 51.8±7 preoperatively and improved to 87.5±5 postoperatively (range, 79 to 94). The Tegner score was 3.0 ± 0.6 preoperatively and improved to 6.6 ± 1.0 postoperatively. The IKDC rating system was shown the normal to near normal 83%. Knee laxity showed that all knees were within 3 mm of anterior displacement (2.3±0.9 mm). The muscular thigh force showed less than 5% deficiency in both extensor and flexor muscles compared with the uninvolved limb. There were no significant complications in any patient. This autogenous bone-hamstring tendon-bone graft with fibrin clot can allow patients to undergo a more aggressive rehabilitative program. These short-term clinical results are promising, but long-term follow up is needed.
