■在前交叉韧带重建(ACLR)后6个月的短期随访中,通过超声成像研究股四头肌腱供体部位的愈合情况,并研究临床结果。
■在2019年3月至2020年8月之间,本研究回顾性纳入了61个膝盖。术中,长度,测量收获的QT移植物的宽度和厚度。在6个月的随访中,患者由五名放射科医生中的一名进行评估,遵循相同的协议来计算缺陷体积,患者在视觉模拟量表上对疼痛进行了自我评估,国际膝关节文献委员会(IKDC)和膝关节损伤和骨关节炎结果评分(KOOS)。
■术中,QT移植物的体积为4635.4±912.5mm3。术后,在6.5±0.7个月时进行超声检查,缺损体积为323.3±389.2mm3,代表供体部位的93%±9%的愈合率。在至少6个月的随访中,IKDC为61.6±16,KOOS为70.2±16.6。年龄与治愈率显着相关(β:-0.005;p=0.032)。
■随访6个月时,根据超声测量,QT供体部位的缺损大小已愈合93±9%,留下的平均缺损体积为323.3mm3.这表明QT在移植物收获后具有很高的愈合能力,10例患者在手术后6个月达到完全缺损闭合。这些发现的临床相关性是股四头肌腱供体部位的愈合率高,但是外科医生应该意识到老年患者的治愈率较低。

UNASSIGNED: To investigate the healing of the quadriceps tendon donor site after partial thickness graft harvesting through
ultrasound imaging at a short-term follow-up of 6-month following anterior cruciate ligament reconstruction (ACLR) and to investigate the clinical outcomes.
UNASSIGNED: Between March 2019 and August 2020, 61 knees were retrospectively included in this study. Intraoperatively, the length, width and thickness of the harvested QT graft were measured. At a 6-month follow-up, patients were assessed by one of five radiologists, following the same protocol to calculate the defect volume, and patients performed a self-evaluation of pain on the Visual Analogue Scale, International Knee Documentation Committee (IKDC) and the Knee injury and Osteoarthritis Outcome Scores (KOOS).
UNASSIGNED: Intraoperatively, the QT grafts had a volume of 4635.4 ± 912.5 mm3. Postoperatively,
ultrasound was performed at 6.5 ± 0.7 months, and the defect volume was 323.3 ± 389.2 mm3, representing a healing rate of 93% ± 9% of the donor site. At a minimum 6-month follow-up, IKDC was 61.6 ± 16 and KOOS was 70.2 ± 16.6. Age was significantly associated with the healing rate (β: -0.005; p = 0.032).
UNASSIGNED: At 6 months follow-up, the defect size of the QT donor site had healed by 93 ± 9% leaving a mean defect volume of 323.3 mm3 according to
ultrasound measurements. This suggests that the QT has a high capacity for healing after graft harvesting, with 10 patients reaching full defect closure 6 months after surgery. The clinical relevance of these findings is that the quadriceps tendon donor site has high rates of healing, but surgeons should be aware of lower healing rates in older patients.
UNASSIGNED: Level IV, retrospective
case series.
