Reconstruction Surgery of the posterior cruciate ligament (PCL) has not yet been fully standardized, and associated rehabilitation protocols have not been clearly defined. The aim of this study is to report the results of a consecutive series of patients who underwent the same surgical technique for isolated PCL reconstruction and were submitted to the same specific rehabilitation protocol. A non-aggressive rehabilitation protocol which protects the graft from excess mechanical stress produces satisfying and reproducible clinical and laxity results in the knee.
Our series included 17 patients who underwent single bundle arthroscopic reconstruction of the PCL with an autologous quadriceps tendon graft and who followed the same non-aggressive rehabilitation protocol. All patients were followed up for an average of 30 months (range 12-60 months). The preoperative evaluation and the last follow-up included objective and subjective IKDC scores as well as the Tegner & Lysholm knee scales. The side to side laxity was measured radiologically with the Telos stress testing device. A statistical analysis was performed to compare preoperative and postoperative results.
Preoperatively, no patients were classified as A or B on the IKDC objective score. At last follow-up visit, 88.2% of patients were classified as A or B. Average side to side anteroposterior laxity was 11.9 mm (range 8-18) in the preoperative evaluation and 3.8mm (range 1-7) in the final follow-up (p=0.01) The average subjective IKDC score was 37.7 before surgery and 74.7 at last follow-up (p< 0.01). The Tegner & Lysholm scores were significantly improved by surgery.
Although the results are still less successful than ACL reconstruction, successful PCL reconstruction results were obtained with a standardized single bundle reconstruction technique and an adapted specific postoperative rehabilitation protocol. A non-aggressive rehabilitation protocol can limit postoperative mechanical stress on the graft.
Retrospective Level IV.
后交叉韧带（PCL）的重建手术尚未完全标准化，相关康复方案也尚未明确界定。本研究旨在报告一组连续患者的结果，这些患者接受了相同的手术技术进行孤立的 PCL 重建，并采用了相同的特定康复方案。非侵袭性康复方案可保护移植物免受过度机械应力的影响，从而在膝关节中产生令人满意且可重复的临床和松弛结果。
我们的系列包括 17 名接受单束关节镜下 PCL 重建术的患者，使用自体股四头肌肌腱移植物，并遵循相同的非侵袭性康复方案。所有患者平均随访 30 个月（范围 12-60 个月）。术前评估和最后随访包括客观和主观 IKDC 评分以及 Tegner 和 Lysholm 膝关节评分。侧方松弛度通过 Telos 压力测试设备进行放射学测量。进行了统计分析以比较术前和术后结果。
术前，没有患者在 IKDC 客观评分中被归类为 A 或 B。在最后随访时，88.2%的患者被归类为 A 或 B。术前平均侧方前后松弛度为 11.9 毫米（范围 8-18），最后随访时为 3.8 毫米（范围 1-7）（p=0.01）。术前平均主观 IKDC 评分为 37.7，最后随访时为 74.7（p<0.01）。Tegner 和 Lysholm 评分通过手术显著改善。
尽管结果仍不如 ACL 重建成功，但通过标准化的单束重建技术和特定的术后康复方案，可以获得成功的 PCL 重建结果。非侵袭性康复方案可以限制移植物的术后机械应力。
