目的探讨关节镜下应用双极射频治疗前交叉韧带重建术后移植物松弛的方法.方法 2002年1月-2003年6月,对12例前交叉韧带重建术后移植物松弛的患者在关节镜下应用双极射频进行紧缩治疗.其中男11例,女1例;年龄18～45岁,平均30岁;采用髌韧带移植重建者5例,采用半腱肌肌腱移植重建者7例.术中双极探头输出功率284 W,组织内温度约为60℃.术后非限制性支架固定患肢,并进行患肢功能锻炼.对所有病例进行随访观察,记录其术膝Lysholm-Tegner评分及临床检查结果,并与术前相比.结果术中可见应用双极射频处理后松弛的韧带逐渐收缩变短.韧带的张力明显提高.麻醉状态下抽屉试验及Lachman试验呈阴性.术后随访5～13个月,平均8个月.术膝Lysholm-Tegner评分平均为88.5分,明显高于术前45.5分(P＜0.01),抽屉试验及Lachman试验呈阴性.所有患者均无不良反应.结论在关节镜下应用双极射频治疗前交叉韧带重建术后移植物松弛,可使松弛的韧带收缩变紧,提高关节的稳定性.该手术方法简单、操作方便.
Objective To introduce the application of bipolar radiofrequency energy in the treatment of elongated anterior cruciate ligament (ACL) reconstruction during arthroscopy.Methods From January 2002 to June 2003, 12 cases whose anterior cruciate ligament reconstruction were elongated accepted the therapy of bipolar radiofrequency energy during arthroscopy. The 12 patients included 11 men and 1 woman with an average age of 30 years ranging from 18 to 45 years old. The ACL grafts were composed of 5 patellar tendons and 7 semitendinosus tendons. The elongated reconstruction were treated by bipolar radiofrequency energy with an output of 284W. This was continued until the elongated reconstruction were tight. After the operation, the patients received unlimited orthosis and were conducted to do functional exercise of the knees. All the patients were followed up. The Lysholm-Tegner score and clinical examination of the knees were recorded and analyzed statistically with paired t text. Results The elongated ACL reconstruction became shrinkage and tighten after treated by bipolar radiofrequency energy. The palpation by hook and Lachman test showed negative results. The follow-up time was 5—13 months, averaged 8 months. The postoperative mean Lysholm-Tegner score of the knee was 88.5, which was significantly higher than that of preoperative score of 45.5(P<0.01). All the patients had no postoperative complications.Conclusion By application of bipolar radiofrequency energy, the elongated ACL reconstruction can be shrunk and tightened to make the knees stabilize. The shrinkage procedure is simple, convenient and effective.
