Bone-patellar tendon-bone (BTB) autograft remains the most widely used graft source for anterior cruciate ligament reconstruction (ACLR). The drawback associated with BTB is increased donor-site morbidity, such as anterior knee pain. The purpose of this study was to evaluate and compare anterior knee pain after refilling the patella bony defect with bone substitute.
This is a retrospective analysis of consecutive patients who underwent BTB ACLR at a single institution between January 2015 and December 2020. The cohort was divided into two groups; one in which the patellar bony defect was refilled with bone substitute (Bone Graft group) and another in which this the bony defects were not treated (No Bone Graft group). Demographic variables, reported anterior knee pain, visual analog scale (VAS) score, complications, re-operation, and patient reported outcome measures, such as the IKDC, LYSHOLM and SF-12 scores, were compared between groups.
A total of 286 patients who underwent BTB ACLR were included. The No Bone Graft group included 88 (30.7%) patients and the Bone Graft group included 198 (69.3%) patients. The Bone Graft group had less anterior knee pain at last clinic follow up (33.3% vs. 51.1% p = 0.004) as well as lower VAS anterior knee pain scores (2.18 vs. 3.13, p = 0.004). The Bone Graft group had lower complications rates (21.7% vs 34.1, p = 0.027). No differences were found in the LYSHOLM, IKDC, and SF-12 scores.
Bone refilling in BTB ACLR significantly reduces prevalence and severity of anterior knee pain. Larger randomized trials are needed to confirm the benefits of bone refilling in ACLR patients.

骨-髌腱-骨（BTB）移植物仍然是前交叉韧带重建（ACLR）最广泛使用的移植物来源。BTB 的缺点是增加了供体部位的发病率，如前膝疼痛。本研究的目的是评估和比较用骨替代物填充髌骨骨缺损后前膝疼痛。
这是对 2015 年 1 月至 2020 年 12 月在一家机构接受 BTB ACLR 的连续患者进行的回顾性分析。该队列分为两组；一组髌骨骨缺损用骨替代物填充（骨移植组），另一组髌骨骨缺损未治疗（无骨移植组）。比较两组间的人口统计学变量、报告的前膝疼痛、视觉模拟量表（VAS）评分、并发症、再手术以及患者报告的结果测量，如 IKDC、LYSHOLM 和 SF-12 评分。
共纳入 286 例接受 BTB ACLR 的患者。无骨移植组 88 例（30.7%），骨移植组 198 例（69.3%）。骨移植组在最后一次临床随访时前膝疼痛较少（33.3%比 51.1%，p=0.004），VAS 前膝疼痛评分也较低（2.18 比 3.13，p=0.004）。骨移植组并发症发生率较低（21.7%比 34.1%，p=0.027）。LYSHOLM、IKDC 和 SF-12 评分无差异。
BTB ACLR 中的骨填充显著降低了前膝疼痛的发生率和严重程度。需要更大的随机试验来证实骨填充在前交叉韧带重建患者中的益处。
