目的：研究前交叉韧带（ACL）部分断裂后采用保守治疗与射频修整手术的疗效差异，指导临床治疗。方法回顾性收集37例 ACL 部分断裂患者，根据治疗方法区别分成2组：保守治疗组（n ＝21）和关节镜下射频修整组（n ＝16）。所有患者随访2年。评价指标包括：国际膝关节文献委员会膝关节评估表（IKDC 评分）、Lysholm 评分、Tegner 评分、膝关节活动度（ROM）和 Kneelax 关节动度测量仪测量结果。结果2组患者膝关节功能评分和 ROM 随访2年结果显著强于受伤后结果（P ＜0．05），kneelax 测量结果伤后2年与受伤时差异无统计学意义（P ＞0．05）。2组患者随访2年时的膝关节功能评分结果、ROM 和 kneelax 测量结果差异无统计学意义（P ＞0．05）。结论ACL 部分断裂后采用保守治疗和关节镜下射频修整疗法都可以显著改善患膝功能，但对膝关节稳定性的恢复没有帮助。%Objective The purpose of this study was to compare the outcomes between conservative treat-ment and thermal modification technique for partial anterior cruciate ligament (ACL)tears.Methods Thirty-seven patients with partial ACL tears were divided into conservative treatment group (n =21)and thermal modification group (n =16).Minimum follow-up was 2 years.Patients were evaluated just after the injury and at the latest follow-up with several parameters,including the International Knee Documentation Committee (IKDC)score,Ly-sholm knee score,Tegner activity rating,range of motion (ROM)and the kneelax arthrometer.Results The func-tional examination outcomes were improved significantly between the results just after injury and at 2 years follow-up in both groups (P <0.05),and the knee laxity outcomes were similar between the two time points (P >0.05). Meanwhile,in terms of functional examination,there were no statistically difference for ROM and knee stability outcomes between the two groups at 2 years follow-up (P > 0.05).Conclusion Our study indicates that both conservative treatment and thermal modification for partial tears of the ACL could improve the knee function,ex-cept for knee stability.
