Outcome Measures

Primary Outcomes (5)

  • side-to-side difference

    The side-to-side difference was measured at final follow-up by KT-2000 arthrometer (MEDmetric, San Diego, California) at 15 lb, 20 lb, and 30 lb in 30° and 90° of flexion.

    Before and 2 to 5 years after the operation

  • total anteroposterior (AP) laxity

    the total AP laxity (by back-pushing KT-2000 arthrometer measurement) of the knee joint were measured. The technique of the back-pushing KT-2000 arthrometer is as follows: at 30° or 90° of flexion, the patient relaxed himself or herself; next, the examiner pushed back the handle of the KT-2000 arthrometer with 20-lb force and set the zero point of the arthrometer while the tibia was kept in a back position. Then, the examiner applied an anterior force of 15 lb, 20 lb, and 30 lb, respectively, and recorded the results as the total AP laxity of the knee joint.

    Before and 2 to 5 years after the operation

  • pivot shift

    The pivot shift test of the knee joint is a test with an accuracy of 99% in the detection of knee anterior cruciate ligament injury.

    Before and 2 to 5 years after the operation

  • range of motion (ROM)

    Knee joint range of motion. Normal flexion 0 to 130°, extension 0°, flexion internal rotation 0 to 30°, flexion external rotation 0 to 40°.

    Before and 2 to 5 years after the operation

  • isokinetic muscle strength evaluation

    muscle strength was evaluated by Biodex dynamometer (Biodex, Shirley, New York) according to the manufacturer's guidelines. Strength testing was performed for knee flexion and knee extension at 60 and 120 deg/s. The mean peak torque of 5 maximal repetitions for each velocity was assessed to analyze the quadriceps and hamstring isokinetic strength, and the results of the operated leg were expressed as a percentage of that of the nonoperated side.

    Before and 2 to 5 years after the operation

Secondary Outcomes (3)

  • International Knee Documentation Committee (IKDC) score

    Before and 2 to 5 years after the operation

  • Tegner score

    Before and 2 to 5 years after the operation

  • Lysholm score

    Before and 2 to 5 years after the operation

Study Arms (3)

BPTB double-bundle allograft group

EXPERIMENTAL

Procedure: BPTB double-bundle allograft

BPTB single-bundle allograft group

ACTIVE COMPARATOR

The patient underwent arthroscopic single-bundle anterior cruciate ligament (ACL) reconstruction with bone-patellar tendon-bone (BPTB) allograft.

Procedure: BPTB single-bundle allograft group

BPTB single-bundle autograft group

ACTIVE COMPARATOR

The patient underwent arthroscopic single-bundle anterior cruciate ligament (ACL) reconstruction with bone-patellar tendon-bone (BPTB) autograft.

Procedure: BPTB single-bundle autograft group

Eligibility Criteria

Age16 Years - 50 Years
Sexall
Healthy VolunteersNo
Age GroupsChild (0-17), Adult (18-64)

You may qualify if:

  • From July 2005 to June 2008, 3757 ACLRs were performed in our department. A total of 111 patients chose to use allografts, and the other patients chose autologous semitendinosus and gracilis tendons (STGs). The patients selected DB or SB reconstruction based on their understanding about the information from the surgeons. Following the criteria of a prospective randomized study, 56 patients undergoing ACLRs with BPTB allografts were included in our study and were divided into a DB group and a SB group, each with 28 patients. 25 DB and 27 SB patients completed the final follow-up. Only patients between 16 and 50 years old who were undergoing primary operation were included, and younger patients had to have radiographic confirmation of a closed epiphysis.
