We present a technical note on 2 patients with post-traumatic symptomatic hyperextension of the knee treated with a new arthroscopic technique. Both patients were of similar ages with similar injuries resulting in an excess of hyperextension at the knee with resulting instability and pain. Both patients had not improved with a variety of nonoperative measures and 1 attempt each at simple arthroscopic debridement of the damaged tissue. Our technique involves carefully scarring the damaged posterior capsule arthroscopically, followed by extension block bracing for 12 weeks. In 2 patients who had not improved with previously described techniques, we achieved a correction of the excess hyperextension with resulting improvement in their symptoms. Two years after surgery, both patients had significantly improved Lysholm and Tegner activity scores and had returned to work. We believe this technique to be reliable and reproducible.
我们介绍了 2 例采用新关节镜技术治疗创伤后膝关节过度伸展症状的患者的技术说明。这 2 例患者年龄相似，损伤相似，导致膝关节过度伸展，出现不稳定和疼痛。这 2 例患者都没有通过各种非手术措施和 1 次简单的关节镜下清创术改善病情。我们的技术包括仔细地在关节镜下对受损的后囊进行瘢痕化处理，然后进行 12 周的伸展固定支具固定。在 2 例先前描述的技术治疗无效的患者中，我们成功地纠正了过度伸展，症状得到了改善。术后 2 年，2 例患者的 Lysholm 和 Tegner 活动评分均显著改善，且已恢复工作。我们认为该技术可靠且可重复。
