Abstract

Backgroud: Allografts are preferred in certain cases of revision anterior cruciate ligament reconstructions to avoid additional graft harvesting and to fill in enlarged tunnels. The clinical outcomes of quadriceps tendon-patellar bone allograft in revision anterior cruciate ligament reconstruction are not well-known. This study was performed to evaluate the clinical outcomes of revision anterior cruciate ligament reconstructions using quadriceps tendon-patellar bone allografts.

Methods: Patients who underwent revision anterior cruciate ligament reconstructions with quadriceps tendon-patellar bone allografts with a minimum follow-up of 2 years were retrospectively reviewed. Their mean follow-up length was 33.5 ± 19.5 months. Outcomes including clinical scores (Lysholm, International Knee Documentation Committee [IKDC], Tegner scale, and Knee injury and Osteoarthritis Outcome Score [KOOS]), knee stability (physical examinations and knee arthrometer), return to sports, and any associated complications were assessed. Degrees of graft synovialization were also evaluated using arthroscopy.

Results: A total of 38 patients were reviewed and their age at the time of surgery and follow-up length were 37.2 ± 12.5 years (range, 17-66 years) and 2.8 ± 1.6 years, respectively. All clinical scores including KOOS, IKDC, Lysholm, and Tegner scale significantly improved at 2 years after surgery and 92.1% of the patients returned to sports. The mean preoperative side-to-side difference in knee arthrometer decreased from 4.5 ± 2.3 mm before surgery to 2.6 ± 1.5 mm after surgery (p < 0.001). Graft synovialization was observed in 13 of 16 patients (81.3%) who underwent second-look arthroscopy. Complication rate was 10.5% (n = 4). All complications were graft re-rupture and occurred at an average of 18 months after revision surgery.

Conclusions: Quadriceps tendon-patellar bone allograft showed satisfactory clinical outcomes in revision anterior cruciate ligament reconstruction and thus could be a good alternative when autograft harvesting is not optimal.

股四头肌腱-髌骨同种异体骨重建翻修前交叉韧带的临床效果满意。
背景:同种异体移植物在某些翻修前交叉韧带重建的病例中是首选的,以避免额外的移植物收获和填充扩大的隧道。股四头肌腱-髌骨异体骨移植在前交叉韧带翻修重建中的临床效果尚不清楚。本研究旨在评估采用股四头肌肌腱-髌骨同种异体骨重建翻修前交叉韧带的临床效果。方法:回顾性分析采用股四头肌肌腱-髌骨异体骨移植行前交叉韧带翻修重建的患者,随访时间至少为2年。平均随访时间为33.5±19.5个月。结果包括临床评分(Lysholm、国际膝关节文献委员会[IKDC]、Tegner量表、膝关节损伤和骨关节炎结局评分[oos])、膝关节稳定性(体格检查和膝关节计)、恢复运动和任何相关并发症的评估。用关节镜评估移植物的滑膜化程度。结果:共回顾38例患者,手术时年龄为37.2±12.5岁(范围17 ~ 66岁),随访时间为2.8±1.6岁。术后2年,包括kos、IKDC、Lysholm和Tegner评分在内的所有临床评分均显著提高,92.1%的患者恢复运动。术前膝关节计的平均侧差由术前的4.5±2.3 mm降至术后的2.6±1.5 mm (p < 0.001)。16例接受二次关节镜检查的患者中有13例(81.3%)观察到移植物滑膜形成。并发症发生率为10.5% (n = 4)。所有并发症均为移植物再破裂,发生时间平均为翻修术后18个月。结论:同种异体股四头肌肌腱-髌骨移植在翻修前交叉韧带重建中具有满意的临床效果,因此在自体骨移植不理想的情况下是一种很好的替代方法。
