The aim of this prospective study was to follow the development of repair tissue in the donor-site area using serial magnetic resonance imaging (MRI) evaluation and to assess whether the MRI findings were correlated with donor-site morbidity. Thirty-seven consecutive patients with unilateral anterior cruciate ligament injuries undergoing elective reconstruction of the ligament were included in the study. They were aged 27 (range 14-50) years. The graft was harvested through two 25-mm vertical incisions with the aim of protecting the infrapatellar nerve and sparing the paratenon. The tendon defect was left open. The patients underwent MRI evaluation at 6 weeks, 6 months and 27 months postoperatively. A final clinical follow-up was made 25 (range 23-29) months postoperatively. MRI demonstrated that the donor-site gap, i.e. the area corresponding to a pathological non-tendinous-like tissue signal, was 9 (range 4-18) mm at 6 weeks, 5 (range 2-14) mm at 6 months and 2 (range 0-5) mm at 27 months. The size of the donor-site gap had significantly decreased at 6 months compared with 6 weeks (P = 0.0001), as well as at 27 months compared with 6 months (P = 0.0001). We conclude that the patellar tendon at the donor site healed gradually, as expressed by a decrease in the area of non-tendinous-like tissue signal on the serial MRI evaluations.
这项前瞻性研究的目的是通过连续磁共振成像（MRI）评估来跟踪供区组织的修复发展情况，并评估MRI结果是否与供区并发症相关。该研究纳入了37例连续的单侧前交叉韧带损伤并接受择期韧带重建的患者。他们的年龄为27岁（范围14 - 50岁）。通过两个25毫米的垂直切口获取移植物，目的是保护髌下神经并保留腱旁组织。肌腱缺损处保持开放。患者在术后6周、6个月和27个月接受MRI评估。术后25（范围23 - 29）个月进行了最终的临床随访。MRI显示，供区间隙，即对应于病理性非腱样组织信号的区域，在6周时为9（范围4 - 18）毫米，6个月时为5（范围2 - 14）毫米，27个月时为2（范围0 - 5）毫米。与6周时相比，6个月时供区间隙大小显著减小（P = 0.0001），与6个月时相比，27个月时也显著减小（P = 0.0001）。我们得出结论，供区的髌腱逐渐愈合，这在连续的MRI评估中表现为非腱样组织信号区域的减小。
