Tibial tunnel enlargement and joint instability after anterior cruciate ligament reconstruction. A prospective comparison between autograft and allograft

Abstract

IVTibial tunnel enlargement and joint instability after anterior cruciate ligament reconstruction. A prospective comparison between autograft and allograft 1 Abstract Purpose: To investigate tibial tunnel widening and knee instability after ACL reconstruction with hamstring autograft or irradiated soft tissue allograft. Methods: Eight-two patients were divided into two groups: autograft group and allograft group. Radiographic and clinical evaluations were performed. Results: Seventy patients were followed up with median of 36.3 months (range 36-38 months). Tibial tunnel widening was at or greater than 30% for nine patients in the autograft group and 15 patients in the allograft group (P = 0.0417). The average percentage of tibial tunnel widening was 26.7 ± 4.0 % and 29.7 ± 5.3 % in autograft and allograft groups, respectively (P = 0.0090). Knee range of motion was not affected by the reconstruction operation or different grafts. Thigh atrophy improved significantly within 24 months after ACL reconstructions in both groups. ACL reconstruction with the allograft leaded to less knee stability than that with the autograft from one year after operation (P = 0.0023). There was no significant difference between two groups with respect to Lysholm score (P = 0.1925) and Tegner score (P =0 .0918) at the final follow-up. Conclusion:The allograft group reported significantly more tibial tunnel widening and knee instability compared with the autograft group.

“…[9,10] Lysholm Knee Rating Scale measured daily living activity level and eight factors were rated to produce an overall score on a point scale of 0 to 100. [11] The Lysholm scale is reliable for use in research on ligament and meniscal injuries, chondral injuries, and patellar dislocation. [12] In the present study, the effectiveness of surgery on patients with ACLR was determined by Lysholm knee score scale.…”

“…Following ACLR patients are at higher risk for ACL injury in bilateral knees, but especially in the contralateral ACL compared to healthy individuals of the same age in the same physical activity [35][36][37]. Tunnel widening/expansion is another gradual onset postoperative process associated with ACLR especially in HST grafts and allografts that may also be associated with knee instability [38,39]. Patients who have ACLR have been noted to have higher risk for osteoarthritis up to 13% if only the ACL is involved, however this number can be as high as 48% when associated with meniscal injury [40].…”
