Abstract

Purpose: To compare the functional and clinical outcomes of knee joints in patients over a 10-year period following posterior cruciate ligament (PCL) reconstruction with single-bundle versus double-bundle.

Methods: Patients who underwent PCL reconstruction were retrospectively analyzed. Based on the surgical approach, they were divided into the single-bundle reconstruction group and the double-bundle reconstruction group. Preoperative and postoperative Lysholm score, International Knee Documentation Committee (IKCD) score, and Tegner activity score were evaluated, and the stability of the joints was assessed using KT-2000 arthrometer. Radiographs were taken at the final follow-up to evaluate the progression of osteoarthritis.

Results: A total of 61 patients were included in the analysis: 26 in the double-bundle group and 35 in the single-bundle group. Baseline data were comparable between the two groups (P > 0.05). There were no significant differences between the two groups in preoperative Lysholm, IKDC score, and Tegner activity score. Postoperatively, these scores were significantly higher at two and ten years follow-up (P < 0.05), with no significant difference between the groups (P > 0.05). There was no significant difference in side-to-side differences (SSD) at 30° and 90° of knee flexion preoperatively between the groups (P > 0.05). Postoperatively, SSD decreased significantly at the two year and ten year follow-up (P < 0.05), with no significant difference between the groups (P > 0.05). For osteoarthritis progression, there were four cases of Kellgren-Lawrence grade ≥ II in the single-bundle group and three cases in the double-bundle group, with no significant difference in the progression of osteoarthritis between the groups (P > 0.05).

Conclusion: Both single-bundle and double-bundle reconstructions for PCL result in good joint stability and mobility, with similar progression of osteoarthritis in long-term follow-up.

Level of evidence: Level III.

后交叉韧带关节镜单束重建与双束重建的临床疗效：一项回顾性研究。

目的：比较单束与双束后交叉韧带（PCL）重建术后 10 年间膝关节的功能和临床疗效：方法：对接受 PCL 重建术的患者进行回顾性分析。方法：对接受 PCL 重建术的患者进行回顾性分析，根据手术方法将其分为单束重建组和双束重建组。评估术前和术后的 Lysholm 评分、国际膝关节文献委员会（IKCD）评分和 Tegner 活动评分，并使用 KT-2000 关节测量仪评估关节的稳定性。最后随访时拍摄X光片以评估骨关节炎的进展情况：共有 61 名患者被纳入分析：26 名在双束组，35 名在单束组。两组的基线数据具有可比性（P > 0.05）。两组患者术前的 Lysholm、IKDC 评分和 Tegner 活动评分无明显差异。术后两年和十年随访时，这些评分明显更高（P 0.05）。两组患者术前膝关节屈曲 30°和 90°时的侧向差异（SSD）无明显差异（P > 0.05）。术后两年和十年随访时，SSD明显下降（P 0.05）。在骨关节炎进展方面，单束组有4例Kellgren-Lawrence分级≥II级，双束组有3例，两组骨关节炎进展无明显差异（P>0.05）：结论：PCL单束重建和双束重建均可获得良好的关节稳定性和活动度，长期随访的骨关节炎进展情况相似：证据等级：三级

期刊介绍： International Orthopaedics, the Official Journal of the Société Internationale de Chirurgie Orthopédique et de Traumatologie (SICOT) , publishes original papers from all over the world. The articles deal with clinical orthopaedic surgery or basic research directly connected with orthopaedic surgery. International Orthopaedics will also link all the members of SICOT by means of an insert that will be concerned with SICOT matters. Finally, it is expected that news and information regarding all aspects of orthopaedic surgery, including meetings, panels, instructional courses, etc. will be brought to the attention of the readers. Manuscripts submitted for publication must contain a statement to the effect that all human studies have been approved by the appropriate ethics committee and have therefore been performed in accordance with the ethical standards laid down in the 1964 Declaration of Helsinki. It should also be stated clearly in the text that all persons gave their informed consent prior to their inclusion in the study. Details that might disclose the identity of the subjects under study should be omitted. Reports of animal experiments must state that the "Principles of laboratory animal care" (NIH publication No. 85-23, revised 1985) were followed, as well as specific national laws (e.g. the current version of the German Law on the Protection of Animals) where applicable. The editors reserve the right to reject manuscripts that do not comply with the above-mentioned requirements. The author will be held responsible for false statements or for failure to fulfil the above-mentioned requirements.
