To systematically review the literature for radiographic prevalence of osteoarthritis (OA) at a minimum of 10 years following anterior cruciate ligament (ACL) reconstruction (ACLR) with anatomic vs. non-anatomic techniques. It was hypothesized that the incidence of OA at long-term follow-up would be lower following anatomic compared to non-anatomic ACLR.
A systematic review was performed by searching PubMed, MEDLINE, EMBASE, and the Cochrane Library, for studies reporting OA prevalence by radiographic classification scales at a minimum of 10 years following ACLR with autograft. Studies were categorized as anatomic if they met or exceeded a score of 8 according the Anatomic ACL Reconstruction Scoring Checklist (AARSC), while those with a score less than 8 were categorized as non-anatomic/non-specified. Secondary outcomes included graft failure and measures of knee stability (KT-1000, Pivot Shift) and functional outcomes [Lysholm, Tegner, subjective and objective International Knee Documentation Committee (IKDC) scores]. OA prevalence on all radiographic scales was recorded and adapted to a normalized scale.
Twenty-six studies were included, of which 5 achieved a score of 8 on the AARSC. Using a normalized OA classification scale, 87 of 375 patients (23.2%) had diagnosed OA at a mean follow-up of 15.3 years after anatomic ACLR and 744 of 1696 patients (43.9%) had OA at mean follow-up of 15.9 years after non-anatomic/non-specified ACLR. The AARSC scores were 9.2 ± 1.3 for anatomic ACLR and 5.1 ± 1.1 for non-anatomic/non-specified ACLR. Secondary outcomes were relatively similar between techniques but inconsistently reported.
This study showed that anatomic ACLR, defined as an AARSC score ≥ 8, was associated with lower OA prevalence at long-term follow-up. Additional studies reporting long-term outcomes following anatomic ACLR are needed, as high-level studies of anatomic ACLR are lacking. The AARSC is a valuable resource in performing and evaluating anatomic ACLR. Anatomic ACLR, as defined by the AARSC, may reduce the long-term risk of post-traumatic OA following ACL injury to a greater extent than non-anatomic ACLR.

系统回顾文献，以评估在前交叉韧带（ACL）重建（ACLR）后至少 10 年，解剖学与非解剖学技术的放射学 OA 患病率。假设与非解剖 ACLR 相比，解剖 ACLR 在长期随访中 OA 的发生率会更低。
通过检索 PubMed、MEDLINE、EMBASE 和 Cochrane 图书馆，对使用自体移植物进行 ACLR 后至少 10 年的放射学分类量表报告 OA 患病率的研究进行系统评价。如果研究符合或超过解剖 ACLR 评分检查表（AARSC）的 8 分，则将其归类为解剖学，而得分低于 8 分的则归类为非解剖学/非特定。次要结局包括移植物失败以及膝关节稳定性（KT-1000、Pivot Shift）和功能结局[Lysholm、Tegner、主观和客观国际膝关节文献委员会（IKDC）评分]的测量。记录所有放射学量表上的 OA 患病率，并将其转换为归一化量表。
共纳入 26 项研究，其中 5 项研究在 AARSC 中达到 8 分。使用归一化 OA 分类量表，在解剖 ACLR 后平均 15.3 年的随访中，375 例患者中有 87 例（23.2%）诊断为 OA，而非解剖学/非特定 ACLR 后平均 15.9 年的随访中，1696 例患者中有 744 例（43.9%）患有 OA。解剖 ACLR 的 AARSC 评分为 9.2±1.3，而非解剖学/非特定 ACLR 的评分为 5.1±1.1。两种技术的次要结局相对相似，但报告不一致。
本研究表明，解剖 ACLR（AARSC 评分≥8）与长期随访中较低的 OA 患病率相关。需要进一步报告解剖 ACLR 的长期结果，因为缺乏高水平的解剖 ACLR 研究。AARSC 是进行和评估解剖 ACLR 的有价值的资源。根据 AARSC 定义的解剖 ACLR 可能比非解剖 ACLR 更能降低 ACL 损伤后创伤后 OA 的长期风险。
