目的探讨膝关节镜下外侧支持带松解联合内侧支持带紧缩术治疗儿童复发性髌骨脱位的疗效。方法 12例16膝髌骨脱位患儿,所有患膝均行关节镜下用等离子刀松解外侧支持带联合内侧支持带紧缩术。观察术后效果。结果术后随访12~36个月,平均随访23.5个月。术前和末次随访IKDC膝关节功能评分分别为(35.4±4.4)分和(90.1±5.3)分;Lysholm膝关节功能综合评分分别为(43.0±5.8)分和(95.7±4.2)分;Tegner下肢运动能力主观评分分别为(3.4±1.7)分和(8.7±0.9)分及患膝NRS疼痛评分分别为(8.9±0.8)分和(2.4±1.2)分,差异均具有统计学意义(P<0.05)。结论膝关节镜下外侧支持带松解联合内侧支持带紧缩术对治疗儿童复发性髌骨脱位有明显效果,术后膝关节功能、下肢运动功能及膝关节疼痛程度较术前均有明显改善,手术疗效满意。
Objective To evaluate the efficacy of knee arthroscopy with lateral support strip release and medial support strip compression in the treatment of recurrent patellar dislocation in children. Methods Twelve patients with patellar dislocation in 16 knees underwent arthroscopy with plasma knife to release the lateral support band and medial support band. Observe the postoperative effect. Results The patients were followed up for 12 to 36 months and were followed up for an average of 23.5 months. The scores of knee function of IKDC before and at the last follow-up were (35.4 ± 4.4) and (90.1 ± 5.3) points, respectively. The Lysholm knee scores were (43.0 ± 5.8) and (95.7 ± 4.2) points respectively. The subjective scores of motor ability were (3.4 ± 1.7) points and (8.7 ± 0.9) points respectively, and the scores of NRS pain scores were (8.9 ± 0.8) and (2.4 ± 1.2) points respectively, the differences were statistically significant (P < 0.05). Conclusions The knee arthroscopy with the release of the lateral support band and the medial support band are effective in treating recurrent patellar dislocation in children. The knee joint function, motor function of the lower extremity and the degree of knee pain were significantly improved after operation. Satisfactory results.
