GENEVA — Bone-patellar tendon-bone and double-looped semitendinosus and gracilis grafts for ACL reconstructions produced results that were not significantly different at short- and long-term follow-up, according to a presenter at the European Society of Sports Traumatology Knee Surgery and Arthroscopy Congress 2012 here.

The researchers found bone-patellar tendon-bone (BPTB) and double-looped semitendinosus and gracilis (DLSG) grafts proved successful for ACL reconstruction, but they noted one technique was not necessarily superior to another in their comparative study of 114 patients. In the study, results for 58 patients in the BPTB group were compared to 56 patients in the DLSG group at 1 year, 2 years and 7 years postoperatively.
“Both groups presented satisfactory objective outcomes in [the] results,” Tone Gifstad, MD, at St. Olavs Hospital, in Trondheim, Norway, said. “There were no differences in anterior knee pain at the 7-year follow-up and there [was] inferior muscle strength in the injured knee compared to the uninjured knee in the hamstring [DLSG] group.”
Furthermore, investigators found no significant differences for the Knee Injury and Osteoarthritis Outcome Scores, Tegner activity scores, mobility, anterior knee pain and Lysholm functional scores. A comparison of mean peak torque and extension in both groups yielded no significant differences, according to the abstract.
Patients reported good or excellent knee function in 73% of cases in the BPTB group and 71% of cases in the DLSG group, according to the abstract. Using the Lachman test, researchers found no significant difference for laxity or maximum manual force with the KT-1000.
Final results were obtained by examination or phone interview for 102 patients (89%), showing 19 patients in the DLSG group and 10 patients in the BPTB group underwent subsequent procedures. Of those surgeries, three patients in the DLSG group and two patients in the BPTB group were ACL revisions, according to the abstract.
All patients followed the same postoperative rehabilitation programs, investigators noted.
