Abstract

PURPOSE
To evaluate the stability, activity level and clinical results of an autologous hamstring and Bone-patellar tendon-bone (BPTB) graft in an Anterior cruciate ligament (ACL) reconstruction.
MATERIALS AND METHODS
Between September 1997 and January 2003, 22 patients with an ACL reconstruction with an autologous four strand hamstring tendon, and 30 patients with a BPTB autograft were enrolled in this study. At the time of the final follow-up, the patients were evaluated by stress radiographs using a Telos instrument, the Lysholm score, Tegner activity score, IKDC activity grades, and anterior kneeling pain.
RESULTS
An evaluation of the anterior laxity using the Telos instrument revealed no significant difference in the hamstring and BPTB groups: side to side difference 2.6 mm in the hamstring group vs 2.3 mm in the BPTB groups (p>0.05). The Lysholm score improved from a preoperative score of 58 to a postoperative score of 88 in the hamstring groups and from 56 to 91 in the BPTB groups. The Tegner score for the hamstring groups was 2.4 preoperatively and 5.8 at the final follow up, and the Tegner score for the BPTB groups were 2.3 and 6.2 preoperatively and after the last follow-up, respectively. The Tegner score was similar in the two treatment groups (p>0.05). According to the IKDC rating system, 9% were normal and 64% were almost normal in the hamstring group. In the BPTB group, 10% were normal and 67% were almost normal. Anterior kneeling pain after a reconstruction with the hamstring tendon autograft (13%) was significantly less common than with the patellar tendon autograft (37%)(p<0.05).
CONCLUSION
The hamstring autograft for an ACL reconstruction decreased the incidence of anterior kneeling pain and produced equivalent clinical results to the BPTB autograft.
