目的针对关节镜下髌骨内侧支持带紧缩术治疗青少年复发性髌骨脱位的效果进行研究。方法选取2013年2月—2017年2月,到该院进行治疗的20例复发性髌骨脱位的青少年患者。对所有患者按照髌骨内侧支持带紧缩术操作标准进行手术治疗并进行术后护理。对患者进行回访,观察其治疗效果。结果在术后即刻,关节适配角、髌骨外侧角、髌骨倾斜角等指标基本恢复正常水平;术后12个月内,各项指标与术前相比,差异有统计学意义(P<0.05);对比髌骨外移距离,术后各个时期与术前对比,以及术后12个月内与24个月对比,差异有统计学意义(P<0.05);对比术后各个时期与术前的膝关节功能,差异有统计学意义(P<0.05)。结论对于青少年复发性髌骨脱位患者,关节镜下髌骨内侧支持带紧缩术治疗方案在矫正维持性方面,效果不够持久,但能够改善膝关节功能。
Objective To study the effect of arthroscopic medial patellar patella retraction for the treatment of recurrent patellar dislocation in adolescents. Methods Twenty patients with recurrent patellar dislocation were selected from February 2013 to February 2017 in our hospital. All patients underwent surgical treatment and postoperative nursing according to the operation standard of patellar medial support band. The patients were interviewed to observe the treatment effect. Results Immediately after operation, indexes such as joint adaptation angle, lateral patellar angle, and patellar tilt angle returned to normal levels. Within 12 months after operation, there were significant differences in various indexes between preoperative and postoperative (P <0.05 ); Compared with the distance of patellar shift, postoperative contrast with preoperative and postoperative 12 months and 24 months, the difference was statistically significant (P <0.05); comparison of postoperative and preoperative Knee function, the difference was statistically significant (P <0.05). Conclusion In patients with recurrent patellar dislocation of the adolescents, the arthroscopic treatment of patellar medial support band with tightening is not effective enough in the maintenance of orthopedic maintenance, but it can improve knee function.
