The lengths of the anteromedial bundle (AMB) and posterolateral bundle (PLB) change during knee motion during double-bundle anterior cruciate ligament (ACL) reconstruction. However, the actual intra-articular graft length would be affected by the bone tunnel position and tunnel creation angle during ACL reconstruction. The aim of this study was to investigate the intra-articular length change of the AMB and PLB in patients who underwent anatomic double-bundle ACL reconstruction.
Hypothesis
We hypothesized that the PLB would show a more dynamic length change pattern than the AMB during knee flexion at ACL reconstruction.
Methods
Thirty-two patients (16?men and 16?women) who had isolated ACL injuries with intact menisci were investigated. Anatomic double-bundle ACL reconstructions were performed using semitendinosus tendon autografts at a mean age of 30.6?years. The graft and tunnel lengths were measured intraoperatively. Intra-articular graft lengths and length changes were calculated at 0 and 90 of knee flexion during ACL reconstruction. Intraoperative data were collected prospectively, and analyses were performed retrospectively.
Results
The intra-articular length of the AMB at 0 of knee flexion was 28.1}5.5mm. At 90 of knee flexion, the AMB intra-articular length decreased to 25.6}4.8mm. The intra-articular length of the PLB decreased to 17.7}4.6mm at 90 of knee flexion compared to 22.0}4.2mm at 0 of knee flexion. Changes in the intra-articular graft length during knee flexion were detected more in the PLB (4.1mm) than in the AMB (2.0mm, p=0.01).
Discussion
This study demonstrated that the intra-articular length change of the PLB during knee motion was larger than that of the AMB in anatomic double-bundle ACL reconstructions with semitendinosus tendon autografts and suspensory femoral fixation devices.
