摘要: This study tested the hypothesis that serial dilation of tibial tunnel could provide a stronger anchorage graft-fixation-device complex compared to traditional extraction drilling. Forty patients (22 men and 18 women) undergoing ACL reconstruction were randomized either drilling (group ED) or compaction by SD) tunnel. Tantalum beads placed in tibia, femur, hamstring graft. Radiostereometric analysis (RSA) was performed postoperatively again after 6, 12, 24 weeks. Migration graft bone tunnels as well knee laxity assessed using RSA TELOS stress device. Six (three three excluded during follow-up, which resulted 17 group ED [median age 30 years (range 20–50)] SD 32 years 20–49)]. The mean migration canal 3 months 1.3 (SD 0.6) mm 0.8 0.5) (P = 0.02). overall 13.0 4.0) 10.9 3.1) SD. found less slippage dilated group. clinical relevance difference is unknown. No radiographic between two groups.
